B 3\nPART B.\nNORTH-WESTERN MINERAL SURVEY DISTRICT (No. 1).\nBY\nJoseph T. Mandy.\nSUMMARY.\nThe steady advance of the mining industry in this district that was evinced in 1936 has\ncontinued during 1937. Increased and continued production has been the governing objective,\nand the year has been featured by the achievement of progressive results in this respect from\npreparatory developments carried out in 1936. During the year production, especially of\ngold, has shown an increase, new producers have materialized, and further advance has been\nmade in the laying of a sound foundation for a possible progression of new producing mines\nin future years.\nActivity in silver and base metals has not shown any marked improvement during the\nyear.\nDuring the year, the B.C. Silver and Sebakwe properties, now consolidated with the\nPremier Gold Mining holdings and operated by the Silbak-Premier Mines, Limited, have been\nbrought into production. In the northern section, on the Taku River the Polaris-Taku\nMining Company, Limited, after considerable exploration and development, completed the\nconstruction of a 200-ton-capacity mill on the Whitewater group, and brought this property\ninto production in September. Steady progress in construction of the Big Missouri underground mill of 750-ton capacity at Stewart has continued, and this property will come into\nproduction early in 1938. Also in the Stewart area, the Dunwell mine and mill continued\nproduction during the season.\nIn the coastal section, the Surf Point and Edye Pass properties have been operated by the\nReward Mining Company, with production from the Surf Point mill. At Surf Inlet the Surf\nInlet Consolidated Gold Mines, Limited, has continued mining and milling as well as exploratory development throughout the year.\nDuring the year production has come from fifteen different properties, of which six were\nmilling operations. The construction of a Government sampling plant at Prince Rupert was\ncompleted in August. Through the purchase and advantageous marketing of ore systematically mined by prospectors, or produced during the course of preliminary exploration, and by\nbulk tests, guidance, and advice, it is hoped to speed up increased development and production,\nespecially along the Canadian National Railway's line into Prince Rupert. Since the plant's\ncompletion, many prospectors have taken advantage of this service and the scope of its utility\nhas expanded.\nThere has been much activity in exploration and development of old prospects by well-\nfinanced operators, especially in the Portland Canal and McDame Creek areas, also on the\npyritic deposits of the Ecstall River near Port Essington, Skeena River, and on the Hidden\nCreek copper deposits at Anyox.\nOperations in connection with placer gold have been active, especially in the Atlin area,\nwhich will show a substantial increase in output, and promises continued expansion with\nindications of the application of additional capital for the mechanized operation of new\nground. Of interest to placer-miners is the discovery of two large gold nuggets, one from\nSquaw Creek, Atlin Division, weighing 46 oz. 5 dwt., and the other from Alice Creek, a\ntributary of Boulder Creek, Turnagain (Little Muddy) River area, weighing 52 oz. 15 dwt.\nProspecting for lode and placer deposits has declined generally, but in some areas has\nbeen active and new discoveries of importance have been made in the American Creek area,\nPortland Canal Mining Division, the Turnagain area, and the Taku River area. Increasing\ninterest has been shown in prospecting for lode deposits in likely gold areas of the interior,\nsuch as the McDame Creek section of the Stikine Mining Division. B 4\nREPORT OF THE MINISTER OF MINES, 1937.\nLODE-GOLD DEPOSITS.\nBear River Area, Stewart, Portland Canal.\nThis group comprises the Oral M., Muriel S., Ann G., May No. 1, and May\nOral M. Group. No. 2 mineral claims and fractions, owned by Premier Gold Mining Company, Limited. The claims were staked by the Premier Company during\n1935 and 1936 on discoveries made by the company's prospectors at the time exploration was\nbeing carried out by the company on the adjoining Molly B. molybdenite showings on Indian\nReserve No. 19.\nOral M. Group, Portland Canal. Plan and Section.\nThe claims are located north of the Gold Axe group and east of Indian Reserve No. 19,\ntowards the base of the westerly slope of Mount Rainey, on the east side and towards the\nmouth of the Bear River, about half a mile easterly from the village of Stewart. The property is reached by boat from the Stewart dock to a location on the tide-fiats on the east bank\nof Bear River, determined by the stage of the tide, a distance of about 1 mile. At low water\nBear River can be crossed to its east bank by pack-horse from Stewart to the commencement\nof the trail at the foot of the hill, about 30 feet above sea-level. If a rowboat is used from\nStewart dock, the tide-fiat and its margin is traversed for about a quarter of a mile to the\ncommencement of the trail. From this point a pack-trail ascends the mountain-slope by a\nseries of switchbacks to the tent-camp at 640 feet elevation, and about three-eighths of a\nmile from the foot of the hill. From the camp a trail extends about 200 feet north-westerly\nto the adit-portal at 600 feet elevation.\nIn the locality of the claims the hill slopes at a general angle of about 20 degrees, and is\ndensely timbered with mainly cedar, hemlock, and spruce trees of appreciable size and is\nthickly overgrown with underbrush. Longitudinal benched rock ridges and knolls of \" roche\nmoutonnee \" form, fronted by rock bluffs, are typical topographical features. Glacial overburden of appreciable thickness in the bench and depression areas covers the hill-slope.\nThe locality is adjacent to a northerly contact of rocks of the Coast Range batholith.\nGranitic rocks outcrop about 750 feet north of the adit-portal, and the contact strikes northeasterly across the central section of the Oral M. and plunges south-easterly under the roof\nrocks which are argillaceous sediments. The rocks adjacent to the intrusive consist of highly\nmetamorphosed argillite of the Lower Hazelton group. Immediately adjacent to the contact, NORTH-WESTERN DISTRICT (No. 1). B 5\nand at the base of the hill, the rocks are hybridized and in the main silicified by marginal\neffects of the intrusive batholith. The marginal absorption-phase is gradually transitional\ntowards the south into a siliceous argillite now containing epidote and spessartite-garnet;\nthis altered rock is definitely banded by the epidote and spessartite. The altered sediments\nstrike north 55 degrees west and dip between 60 and 76 degrees south-westerly.\nThe mineral deposit consists of an irregular zone of silicification from 3 to 17 feet wide\nin the altered argillite and is conformable with the attitude of the formation. The zone has\nbeen exposed about 750 feet southerly of the batholith contact, and strikes at an obtuse angle\nto the contact. Silicification in this zone appears to be associated with slight shearing along\nfractures generally conformable with the bedding of the sediments, and to be best developed\nin the localities of slightly sheared cross-fractures striking north 26 to 31 degrees east, with\na vertical to 45-degree dip north-westerly. Stringers, bands, patches, and small lenses of\nquartz are irregularly distributed in the zone, especially in the locality of the cross-fractures.\nThe zone is generally mineralized with finely-disseminated pyrrhotite, but in some sections,\nespecially in the areas of cross-fractures, it contains stringers, blebs, and patches of massive\npyrrhotite with chalcopyrite across widths of from 2 to 9 feet.\nDuring 1935 and 1936, the zone was explored by stripping and open-cutting and traced\non the surface between 590 and 840 feet elevation for a distance of about 640 feet southeasterly from the east boundary of the Indian reserve. During 1936, the zone was also\nexplored by seven diamond-drill holes. In the 1937 season, a contract was let to K. F. Pond,\nof Stewart, for further exploration by drifting on the zone from an adit at 600 feet elevation.\nAt the time of examination on August 27th, a crew of four men was employed, and the drift\nhad been advanced 131 feet.\nAt 590 feet elevation on a knoll adjacent to the Indian reserve, stripping for 20 feet\nexposes silicified argillite with garnet and epidote bands, quartz stringers and patches, mineralized with films and blebs of pyrrhotite and chalcopyrite across a width of 40 inches. At\nthis locality the zone strikes north 54 degrees west and dips 65 degrees south-westerly. A\nsample across 37 inches assayed: Gold, 0.24 oz. per ton; silver, 1.8 oz. per ton; copper, 0.3\nper cent. The continuation of the zone down the face of the bluff to the north-west on the\nIndian reserve could be seen, but it was inaccessible for examination.\nAt 600 feet elevation, 40 feet south-easterly of this, slightly silicified argillite with some\nquartz stringers and sparsely disseminated pyrrhotite and a little chalcopyrite 1.5 to 4 feet\nwide is exposed in the face of a low bluff by stripping for a length of 55 feet. The adit-\nportal is in the face of the bluff on the hanging-wall side of the zone.\nAt 640 feet elevation, 30 feet south-easterly of this, silicified argillite with stringers,\nbands, and lenses of quartz from 9 to 14 feet wide is exposed by stripping and in the face of\na sloping bluff for a length of 108 feet to 710 feet elevation. In this section the zone strikes\nnorth 55 degrees west, dips 60 degrees south-westerly, and is generally well-mineralized with\nstringers, blebs, patches, and disseminated pyrrhotite and some chalcopyrite. Several transverse fractures striking northerly and dipping westerly cut across the zone in this exposure.\nA composite chip sample for a length of 46 feet along the easterly section of the exposure,\nand across an average width of 9 feet, assayed: Gold, 0.10 oz. per ton; silver, 0.30 oz. per\nton; copper, 0.8 per cent.\nSouth-easterly of this exposure, for a distance of 95 feet, continuity is obscured by deep\nglacial overburden. Two pits excavated in this had not encountered bed-rock.\nAt 740 feet elevation, silicified argillite with quartz stringers and bands is exposed for a\nlength of 70 feet by stripping, and in the sloping face of a rock knoll to 765 feet elevation.\nIn the westerly section of the exposure, stringers and bands of quartz are spread across a\nwidth of 17 feet, with one main band 2 feet wide converging into the zone from the foot-wall.\nThe lower section of the exposure is very sparsely mineralized, but the upper and more compact section is moderately mineralized across a width of 6.75 feet with films, blebs, and disseminated pyrrhotite and with some chalcopyrite. A chip sample across 34 inches of the best\nmineralized section assayed: Gold, 0.20 oz. per ton; silver, 1.6 oz. per ton; copper, trace.\nFor a distance of 190 feet south-easterly, to 840 feet elevation, the continuity of the zone\nis obscured by overburden. At 840 feet elevation, slight silicification with some quartz\nstringers and sparsely disseminated pyrrhotite in altered argillite is exposed in the face of\na bluff.

B 7\nAt 600 feet elevation an adit has been driven on the zone in a general direction of south\n58 degrees east. At the time of examination it had been advanced 131 feet. At the portal\nthe zone strikes north 55 degrees west and dips 65 degrees south-westerly. The adit starts\non the hanging-wall and for the first 15 feet veers easterly across the zone to the foot-wall,\nthen gradually angles southerly again to the hanging-wall. At 50 feet from the portal the\ndrift turns northerly at a cross-fracture towards the foot-wall, and continues in the zone to\nthe face. For the first 50 feet from the portal to this fracture the zone is fairly well-defined\nand composed of silicified argillite with quartz stringers and bands, and mineralized with disseminated pyrrhotite and some chalcopyrite. From this point for 50 feet the silicification\nand mineralization appears to weaken. For the last 30 feet to the face silicification increases,\nand quartz stringers and patches are erratically distributed in the zone with disseminated\npyrrhotite and some chalcopyrite. A sample across 19 inches of silicification on the north\nwall of the drift, 113 feet from the portal, assayed: Gold, 0.30 oz. per ton; silver, 1.80 oz.\nper ton; copper, 2 per cent.\nThis company, with head office at 101 Pemberton Building, Victoria, was\nDunwell Mines, incorporated in 1922 as a specially limited reorganization of Nass River\nLtd. (N.P.L.). Lands, Limited, which was incorporated in 1913. The capitalization of the\nDunwell Mines, Limited, was originally $350,000, but this was doubled in\n1925, and further increased in 1926 to $1,000,000, divided into 1,000,000 shares of $1 par\nvalue each, of which 840,000 have been issued. Late in 1933 a debenture issue of $18,000\nwas authorized to provide funds for rehabilitation and resumption of operations. The property was originally owned by Stewart Bros, and W. Noble, of Stewart, and in the holdings\nare now included the claims of the old Stewart Mining and Development Company.\nThe property consists of twenty-four Crown-granted claims and fractions on which taxes\nhave been paid to December 31st, 1937. The claims are situated on the north side of Glacier\nCreek, on the thickly-timbered south slope of the \" Dunwell \" hill towards the confluence of\nGlacier Creek with the Bear River, at elevations of 1,000 to 2,000 feet. The hill-slope in the\nlocality of the claims is featured by longitudinal bench and ridge areas with an average slope\nof about 20 degrees and a generally thick overburden of glacial debris, densely overgrown\nwith underbrush between the hemlock, balsam, and cedar trees.\nThe property is reached by the Stewart-Bear River Motor-road from Stewart dock to\nthe mill and power camp at 200 feet elevation, a distance of 5% miles. From this locality a\nbranch motor-road ascends the hill-slope for about 1% miles to the mine camp at 1,250 feet\nelevation. This camp is equipped with bunk-house, wash-room, dining-room, kitchen, and\noffice buildings. Branch trails extend to the various workings.\nThe mineral deposit occurs in a main sheared fault-zone constituting the west fault of\nthe \" Portland Canal Fissure Zone \" and striking northerly and dipping westerly, with lateral\nveins carrying silver-lead-zinc mineralization with gold values in places, striking north-westerly and dipping south-westerly. The formation is a series of argillaceous sediments of the\nLower Hazelton (Bitter Creek Series) group which strike northerly, dip from 30 to 60 degrees\nwesterly, and are on the westerly limb of an open anticlinal structure. The locality of the\nworkings is about a quarter of a mile east of the easterly contact of the southerly-plunging\n\" Ben Ali \" granitic stock, and about 1,000 feet east of the contact of the Bitter Creek argillite with the overlying tuffs, greenstones, and argillites of the Bear River Series. Granitic\nand grey lamprophyre dykes intrude the formation, and the veins are sometimes associated\nwith the latter.\nEarly exploration was carried out by the Stewart Mining and Development Company.\nIn 1926 an aerial tramway about 1 mile long and a concentrating-mill of 100 tons daily\ncapacity were constructed. Milling began early in 1927 and ceased later in the same year\nwith the depletion of the then-known ore reserves.\nProduction from this operation amounted to 27,067 tons of ore, from which was recovered\n4,805 oz. gold, 102,199 oz. silver, 1,264,787 lb. lead, and 1,608,634 lb. zinc. Some electrical\nprospecting by the Radiore Company of Canada, followed by diamond-drilling, was carried\nout during 1928 and 1929 with negative results. The property remained inactive until worked\nby lessees in 1932 and 1933, when from small-scale hand-operations about 1,767 tons of ore\nwas produced, yielding 640 oz. gold, 28,653 oz. silver, 4,744 lb. copper, 57,237 lb. lead, and\n2,400 lb. of zinc. Subsequent to this, more extended leasing operations by individual partner- B 8 REPORT OF THE MINISTER OF MINES, 1937.\nships and a Stewart syndicate were carried on until the season of 1935, when the property\nwas also operated for four months by the Dunwell Company. Production for this period\namounted to 7,139 tons of ore, from which was recovered 1,489 oz. gold, 44,331 oz. silver,\n2,184 lb. copper, and 19,553 lb. lead.\nIn the interval some of the mill machinery was sold to Bralorne Mines, Limited. In 1936\nthe Welldun Mining, Milling, and Power Company, Limited, composed mainly of Stewart\ninterests, took a four-year lease on the property. This is a private company incorporated in\nBritish Columbia on April 17th, 1936, and capitalized at $20,000, divided into 40,000 shares\nof 50 cents par value, of which 15,384 shares were reported issued as at July 1st, 1937. The\nhead office of the Welldun Company is at Stewart, and N. E. Nelson, Vancouver, is president.\nThis company reconditioned the mill to a daily milling capacity of 25 tons and operated\nseasonally until the early winter of 1937. Production from this operation to the end of 1937\namounted to 7,885 tons of ore, from which was recovered 1,702 oz. gold, 49,346 oz. silver,\n7,343 lb. copper, and 190,384 lb. lead.\nReferences to the property are contained in the Annual Reports of the Minister of Mines\nfor the years 1920, 1922 to 1929, inclusive, and 1932 to 1936, inclusive. The property is also\n\u00E2\u0096\u00A0described in Memoir 159, Geological Survey of Canada, 1929.\nSurface exposures on the Dunwell have not been sufficiently correlated to definitely\nidentify the vein-structures exposed. One main shear-structure (west fault) with a strike\nabout north and a dip 50 degrees west, extending throughout the length of the property, is\nindicated. Smaller more or less parallel lateral veins converge towards and join it at acute\nangles along the strike and dip. The vein-structures are frequently accompanied by pre-\nmineral lamprophyre dykes. These were probably intruded along already-formed shears and\nsubjected to subsequent stresses; they appear to have had a controlling influence on later\nmineralizing solutions. Mineralization of the ore-shoots and lenses consists mainly of a\nquartz-calcite gangue with sphalerite, galena, pyrite, and tetrahedrite. Argentite, ruby silver,\nnative silver, and probably some electrum constitute very high-grade ore in places.\nCommercial-grade ore in short shoots or lenses seems to favour intersections of the lateral\nveins with the main north-south structure, but occurs in both structures. There is no definite\nevidence to indicate that commercial ore is confined solely to these vein-intersections and their\nvicinity, and further development may show a wider ore-distribution. Underground mining\nin the old 1927 operation through No. 4, No. 3, and No. 2 adits was confined principally to\none ore-shoot occurring apparently around one such vein-intersection, but in the extensive\nunderground workings and in surface exposures commercial mineralization is indicated at\nplaces at appreciable distances north and south of this formerly mined area.\nIn the northern area of the group on the Sunbear.t there appears to be a main north-south\nstructure with lateral veins converging towards it in its southerly extension. On the extreme\nnorth end of the Sunbeam and adjacent to the Victoria group south line at 1,820 feet elevation and 570 feet higher than No. 4 adit, an open-cut and incline shaft about 8 feet deep\nexposes a well-defined vein 6 feet wide which strikes north 10 degrees east to about north,\nand dips 50 degrees west. This is the so-called \" Sunbeam \" vein. It is well mineralized in\nplaces with galena and sphalerite and contains an 8-inch stringer mineralized with tetrahedrite and some argentite. This showing is about 200 feet west of the so-called \" Dunwell \"\nvein which is probably the northerly continuation of the west fault, but the two structures\nseem to converge and possibly may join in this area. This locality is about 370 feet higher\nand about 1,700 feet north of the north end of the No. 3 adit north drift, which is the nearest\nmain underground working. From this point the \" Sunbeam \" vein is traced south for about\n450 feet by a series of pits and cuts along a well-defined depression to 1,780 feet elevation,\nand shows oxidized vein-material, mineralized in places with pyrite, galena, sphalerite, some\ntetrahedrite, argentite, and native silver, and generally associated with a grey dyke. In the\nsouthern 150 feet of this draw the vein is appreciably sheared, from 3 to 5 feet wide, strikes\nnorth and dips 40 to 50 degrees west. In places, a well-mineralized streak 8 to 10 inches wide,\nin places showing argentite and native silver, occurs on the hanging-wall.\nFrom this locality, lessees in 1932 and 1933 shipped about 100 tons of high-grade ore\nfrom shallow cuts and pits, and about 200 tons of possible milling-grade ore still remains on\nthe dumps. The northerly 300 feet which is covered by overburden may contain some continuation of the high-grade ore in this ore-shoot. NORTH-WESTERN DISTRICT (No. 1). B 9\nThe \" Sunbeam \" vein has been traced a further 150 feet, to 1,758 feet elevation, by two\ncuts and a short crosscut-adit. These workings are in bad condition for examination, but\nshow oxidized vein-structure and the grey dyke. About 200 feet easterly of the open-cut at\nan elevation of 1,780 feet, or about 70 feet higher, two oxidized and caved cuts expose what\nappears to be a more or less parallel structure, dipping 50 degrees west on the east side of\na wide felsite dyke. This is known as the \" Sulphide \" vein.\nAt 1,630 feet elevation and about 300 feet west of the cuts at 1,780 feet elevation, the\n\" Sunbeam \" crosscut adit, bearing south 85 degrees east and about 500 feet long, intersects\nat about 300 feet a sheared and brecciated siliceous vein, 4 feet in width. This strikes north\n10 degrees west, dips 60 degrees west, and is very sparsely mineralized. A short drift shows\nquartz stringers with very sparse mineralization. At about 170 feet from the portal a barren\nquartz vein with stringers across 2 feet is also intersected. Further exploration by raising\nwould be required to correlate these veins with the \" Sunbeam \" and \" Sulphide \" veins.\nAt 1,740 feet elevation, 300 feet south of the old lessees' workings, an old cut in the creek-\ndraw is reported to have crosscut two veins striking north and dipping west that may possibly\nbe the southerly continuation of the \" Sunbeam \" vein. About 40 feet east of this and on the\nnorth side of a branch creek-canyon bearing east-west, a short adit exposes crushed and\nsheared siliceous material in a structure striking north 10 degrees east and dipping 50 degrees\nwest. At intervals for 160 feet north-easterly of this, three cuts expose a vein striking northerly and dipping 45 degrees west, mineralized in places with pyrite, sphalerite, and galena.\nOn the south side of the branch-canyon, at its junction with the main creek-trough a short\nadit exposes a crushed and distorted quartz vein 4 feet wide. In the main north-south creek-\nbed about 50 feet southerly of the east-west creek a small exposure of vein-matter well-\nmineralized with galena, sphalerite, and some argentite is seen. The southerly extension of\nthe vein or veins exposed in the two short adits probably forms a junction in this locality with\nthe vein in the main creek-trough, which is probably the southerly extension of the \" Sunbeam \" vein. This locality is about 950 feet north of the face of No. 3 adit north drift and\nfrom 260 to 300 feet higher in elevation.\nAbout 60 feet east of the main creek-trough and along a distance of 200 feet south to\n1,705 feet elevation, four caved trenches and open-cuts expose oxidized argillite and some\nnarrow, grey lamprophyre dykes. About 300 feet east of the main draw and distributed\nalong a gently-sloping bench for a distance of about 700 feet south of the east-west branch-\ncanyon are several old caved and overgrown trenches and cuts.\nUnless intersecting faults have disturbed their alignment, the vein or veins occurring\nalong the trough of the main creek in the central section of the Sunbeam claim cannot be\ncorrelated with those exposed in the main underground workings of No. 1, No. 2, No. 3, and\nNo. 4 adits. It is probable that they are more or less \" en echelon \" veins aligned at acute\nangles to a main shear-structure which occupies the bed of the main creek-trough. This vein-\ncombination would then resemble a \" herring-bone \" form of structure.\nThe main underground workings and exposures from the old work in No. 4 adit, and\nbetween this and slightly above No. 3 adit, are discussed in detail in the Annual Report of\nthe Minister of Mines for 1933. Since then operations have proceeded with the stoping of\nore-lenses below the floor of No. 3 level and above the sub-level at 62 feet below No. 3, along\nthe dip of the vein, and for a length of about 300 feet. Some stoping in the back of No. 3\nlevel, lateral to the main stope between No. 3 and No. 2 levels, has also been done. On a\nmore recently discovered vein, on the hanging-wall side of the dyke which accompanies the\nNo. 3 level vein, stoping was started 45 feet above No. 4 level and carried to a slope-height\nof 290 feet above No. 4 level, and 120 feet above No. 3 level or 212 feet and 87 feet vertically\nabove these levels, at which point operations were proceeding in August, 1937.\nThese underground workings on the Ben Hur claim from No. 1, No. 2, No. 3, and No. 4\nadits are on the west fault structure, with closely-spaced and acutely-angled lateral veins.\nNo. 4 crosscut-adit at an elevation of 1,250 feet intersects this main vein-structure at 960 feet\nin. From the portal to about 480 feet, several small quartz veins from 2 to 30 inches wide\nare intersected and should receive some exploration in the direction of their possible junction\nwith the west fault. At 480 feet from the portal a silicified shear-zone 20 feet wide, with\nsome pyrrhotite and arsenopyrite mineralization, is worth exploration. At the end of the\ncrosscut adit a vein has been drifted on for 380 feet north. For the first 220 feet the vein is B 10\nREPORT OF THE MINISTER OF MINES, 1937.\n3 to 5 feet wide and fairly well-mineralized with galena, sphalerite, and pyrite, and sections\nof it may possibly make milling-grade ore. At 40 feet along the drift a crosscut-intersection\nstope and chute entry have been installed. Commencing 69 feet above the drift-level or 94\nfeet on the dip, the vein has been stoped out for 174 feet on the dip to No. 3 level along a\nlength of about 120 feet. Some milling-grade ore may still remain in the drift-back of the\nstope. Below the drift-level between station 412 and the main crosscut (a length of about\n220 feet) there is a possibility of developing ore along what appears to be the southerly rake\nof this ore-shoot. North of station 412 the drift continues 160 feet to the face, with the\nshearing gradually diminishing along the dyke which accompanies the vein. At about 100\nfeet along the drift north of the main crosscut, a winze reported to be 101 feet deep on the\nvein and a sub-level were inaccessible for examination.\nNo.I Level El. 1704'\nLongitudinal Projection in Plane of Vein\n(Strike North, dip 45-50\u00C2\u00B0W)\nBreast of new stope Aug.23^1937\nWidth (Mold 0z.5ilver%Lopper%Lead%Zmc\n3-4 D.OB 0.2 Tr.

B 11\nAt 1,450 feet elevation, No. 3 crosscut adit, 200 feet higher in elevation than No. 4 adit,\nintersects the main vein-structure at about 450 feet from the portal. Near the point of intersection an area about 190 feet in height (vertical) and averaging about 90 feet long was stoped\nout in 1927 between No. 1, No. 2, and No. 3 south raises along the upward extension of the\nore-shoot from No. 4 level through No. 3 level to slightly above No. 2 level. Since workings\non No. 3 level were described in detail in the Annual Report of the Minister of Mines for\n1933, stoping has been continued and extended south to No. 4 south raise and north to No. 2\nnorth raise for a height of from 15 to 30 feet above the drift-level in these lateral sections.\nNorth of this, further stoping has also been done in the back of the drift north of No. 4 north\nraise for a length of 110 feet and for a height of from 20 to 47 feet. A small amount of\nstoping was also done in the drift-back north and south of No. 9 north raise for a length of\n70 feet, and a few feet above the back.\nThe new hanging-wall stope on the hanging-wall side of the dyke and directly over and\nabout 50 feet in the hanging-wall of the old main stope at its breast has already been referred\nto. This is along the junction area of this vein with the west fault. At the time of examination in August, 1937, this stope had advanced about 87 feet above No. 3 level. In the back\nthe vein is 4 feet wide and well-mineralized with pyrite, galena, and sphalerite. A sample\non the south side of this stope-breast assayed: Gold, 0.08 oz. per ton; silver, 0.2 oz. per ton;\ncopper, trace; lead, nil; zinc, 0.1 per cent. A sample across 4 feet on the north side of the\nstope-breast assayed: Gold, 0.30 oz. per ton; silver, 0.7 oz. per ton; copper, trace; lead,\n2.1 per cent.; zinc, 0.4 per cent. The stope-breast is south of the actual junction of this vein\nwith the main north-south structure and could be extended to the north to the actual junction\nlocality. Further exploration of the junction could be done by raising to No. 2 and No. 1\nlevels.\nNo new work has been done in No. 2 and No. 1 adits, and further exploration of intersected structures towards the north would explore possible junctions of these with the west\nfault on its foot-wall side.\nIn the southern section of the property, on the George E. claim, about 200 feet lower than\nNo. 4 level, there are two old adits on the east and west side of a deep canyon. The canyon\nprobably coincides with the west fault or main north-south structure, and marked shearing\nwith siliceous vein-matter of appreciable width can be seen along its base, especially towards\nits south end on the George E. claim and extending into the Glacier Creek property. The old\nadits on the east and west sides of the canyon are probably on veins converging laterally\ntowards the west fault on its foot- and hanging-wall sides. The portal of the adit on the\neast side of the canyon at 1,015 feet elevation was caved.\nDuring the season of 1937, Art Cameron, of Stewart, with one man, carried out leasing\noperations on the George E. vein, which outcrops in the canyon-wall on the east side of the\ncreek and in the creek-bed, about 25 feet north of the east adit portal and at 10 feet higher\nelevation. At this point an old open-cut along the canyon-wall, 70 to 80 feet above the adit,\nwas excavated for a length of 70 feet to the brow of the canyon at about 100 feet higher\nelevation. At 1,077 feet elevation, and 10 feet south of the southerly side of this open-cut, a\ncrosscut adit to the east for 16 feet intersects a quartz vein 6 feet wide in the face, striking\nnorth 12 degrees west and dipping 48 degrees westerly and mineralized with pyrite and some\ngalena. An old open-cut in the south face of the main canyon open-cut at an elevation of\n1,143 feet exposes oxidized vein-material. At an elevation of 1,165 feet, an adit 6 feet long\nin the south face of the canyon open-cut exposes a vein 18 inches wide striking north 50\ndegrees west and dipping 60 degrees south-westerly. A sample across 10 inches on the\nhanging-wall of this vein assayed: Gold, 0.16 oz. per ton; silver, 24.6 oz. per ton; copper,\ntrace; lead, 2.8 per cent.; zinc, 1.2 per cent. It is reported by Cameron that about 25 tons\nof ore was mined and shipped from the open-cut in the wall of the canyon in the early days.\nDuring the 1937 season, Cameron continued the open-cut in the canyon-wall for a length\nof about 80 feet along its base. This work exposes a well-defined vein 4 to 5 feet wide, well-\nmineralized with galena, sphalerite, and pyrite. A sample across 5.1 feet in the hanging-wall\nof the main vein exposed in the floor of the cut towards its south end, and mineralized with\npatches and blebs of pyrite, galena, and sphalerite, assayed: Gold, 0.10 oz. per ton; silver,\n4 oz. per ton; copper, nil; lead, 2.7 per cent.; zinc, 5.4 per cent. A sample across 4.1 feet\nof the main vein in the floor of the north side of the cut, mineralized with massive galena and B 12 REPORT OF THE MINISTER OF MINES, 1937,\nappreciably oxidized, assayed: Gold, 0.46 oz. per ton; silver, 12 oz. per ton; copper, trace;\nlead, 7.4 per cent.; zinc, 0.2 per cent. From this open-cut A. Cameron mined and shipped to\nthe Dunwell mill during the 1937 season 5 tons, which yielded 2 oz. gold, 39 oz. silver, and\n865 lb. lead. Further exploration of this vein could be carried out by drifting north to its\njunction with the foot-wall of the West Fault and by raising and possibly stoping from the\nadit-level at an elevation of 1,015 feet.\nOn the west side of the canyon at 1,040 feet elevation and 60 feet north-westerly, an\nadit has been driven on a vein occurring on the hanging-wall of the west fault. This is about\n500 feet long and was started on a vein 4 to 5 feet wide which follows a dyke and strikes\nnorth 15 degrees east and dips 50 degrees west. The working is very crooked and appears to\ntrend to the east off the vein at 170 feet from the portal, following a slip. The vein is fairly\nwell mineralized from the portal to the winze, a distance of about 150 feet. At the winze,\nsaid to be 57 feet deep, the vein is 3 to 4 feet wide. The main working continues along a\nslip on a winding course and shows shearing, calcite, and a little pyrite in the face. At 100\nfeet from the face a small vein is intersected. A crosscut to the west from near the face\nintersects a vein, which is drifted on north and south for about 100 feet. The vein is 18\ninches to 6 feet wide and well mineralized in places. About 35 feet from the start of this\ndrift the vein is 4 to 6 feet wide and well mineralized, and a sample across 5 feet assayed:\nGold, 0.5 oz. per ton; silver, 17 oz. per ton; copper, trace; lead, 28 per cent.; zinc, 5 per cent.\nA small shoot of ore from this showing was mined out by lessees during 1934, and this\nworking has not been examined since that time.\nOn the Ben Ali claim, adjoining the Ben Hur on the west, a well-defined sheared quartz\nvein is exposed in open-cuts and adits along a horizontal length of 350 feet and height of 250\nfeet. The vein strikes north 40 degrees west, dips 80 degrees south-westerly, and varies from\n20 to 48 inches in width. Mineralization consists chiefly of pyrite with some sphalerite and\na little chalcopyrite. This ore assays about 0.5 oz. gold and about 1 oz. silver per ton. This\ndeposit and the workings on it are described in the Annual Report of the Minister of Mines\nfor 1933, and mining by lessees has been intermittently carried on up to and including the\n1937 season, when only a small tonnage of probable ore was evident in the workings.\nConclusion.\u00E2\u0080\u0094Examinations of the main Dunwell vein-exposures and workings have indicated a possible ore-horizon in the known veins of from 300 to 400 feet deep on the dip, raking\nfrom north to south. Its preservation in any given locality along the strike and dip of the\nstructure is dependent on the extent of erosion which has effected the topography. In this\nhorizon, mineral concentrations are lenticularly distributed, and appear to favour the localities of junctions of lateral veins with the west fault or with each other. Secondary enrichment of primary sulphides with silver minerals seems also to have occurred in sections of\nthese localities.\nIn the locality of junctions, the lateral veins appear to be dragged to more obtuse\nangles of strike relative to the west fault, both on its foot- and hanging-wall sides, suggesting\nfaulting by this structure and possible relation of the veins on the foot- and hanging-wall\nsides. Along the extension of the lateral veins south-easterly from the foot-wall and northwesterly from the hanging-wall, the lateral vein-fracturing appears to rapidly diminish in\nintensity.\nIt is indicated that the possible zonal ore-horizon may be structurally related to and\nconformable with the southerly plunge of the Ben Ali granitic stock, which outcrops about\n1,500 feet to the westward of the main Dunwell workings.\nThis company was incorporated in 1909, with a capitalization of 1,000,000\nGlacier Creek shares of 50 cents par value. R. M. Stewart, of Victoria, is president and\nMining Co., Ltd. managing director, and the registered office is at 101 Pemberton Building,\nVictoria. The property consists of the Nellie V., Riverside, Last Chance,\nLucky Boy, Lulu, Victory, Micmac, Nellie Fraction, O.K. Fraction, and Wolverine Fraction\nCrown-granted claims and fractional claims, totalling 308.81 acres, on which a total of\n$115.25 in taxes is due to the end of 1937. It is situated on the north side of Glacier Creek,\nbetween 400 and 1,200 feet elevation, about 4% miles by road from the town of Stewart, and\nadjoins the Dunwell on the south.\nOnly a very small amount of surface exploration has been done along the vein outcrops.\nStarting in 1910, intermittent exploration by cross-cutting, drifting, and a small amount of\ndiamond-drilling was done on the property up to about 1925, but in recent years no work was NORTH-WESTERN DISTRICT (No. 1).\nB 13\nSUNBEAM\nLEGEND\nGlacier Creek\nMining Cd.claims\nVei n\nFault\nDip\nGlacier Creek Mining Co., Ltd., and Dunwell Mines, Ltd. Main Workings. B 14\nREPORT OF THE MINISTER OF MINES, 1937.\ndone until 1934. In 1934, the main crosscut adit at about 830 feet elevation was continued\nfor about 200 feet to the intersection of a vein at 795 feet from the portal. Drifting on this\nvein was carried out in the early spring of 1935, and ceased in May of that year. Since that\ntime no work has been done except for a short period of leasing by one man on the Lucky\nBoy vein.\nThe property is reached by the Stewart-Bear River Motor-road from the Stewart wharf\nto Glacier Creek bridge at 200 feet elevation, a distance of 5% miles. From this point the\nbranch motor-road to the Dunwell mine ascending the 27-degree ridge-slope is followed for\nabout 1 mile to 850 feet elevation, whence a wide trail extends for about a quarter of a mile\nto the main workings at about 830 feet elevation.\nThe claims are located on the thickly-timbered, benched and ridged southerly slope to\nGlacier Creek of the \" Dunwell \" hill. In the locality of the claims, the hill-slope varies from\nabout 10 to 37 degrees and is thickly covered with glacial debris and a dense growth of\nunderbrush between the hemlock, cedar, and spruce trees.\nThe mineral-deposit, consisting of quartz veins generally sparingly mineralized with\npyrite, galena, and sphalerite, occurs in argillaceous sediments of the Lower Hazelton (Bitter\nCreek Series) group. The area embraces part of the westerly limb of an open anticlinal\nstructure. The veins occupy shears striking north-westerly and dipping from about 30 to 60\ndegrees south-westerly and are partly conformable to the attitude of the formation. They\nare characteristically brecciated and contain unaltered fragments of the argillite wall-rock.\nWith the exception of one vein occurring on the Lucky Boy claim at an elevation of 560 feet,\nall the known veins on this property occur between, and strike at a slight angle to, two\nmajor faults about 1,000 feet apart which strike north and dip west and constitute what is\nknown as the \" Portland Canal Fissure Zone.\" The Lucky Boy vein occurs on the west side\nof the more westerly fault. The structural difference between the veins on this property and\nthose on the adjoining Dunwell is that, if projected, they would intersect the hanging-wall\nof the east fault, whereas the Dunwell veins intersect the foot-wall of the west fault. This\ndifference may have influenced the process of mineralization. The projection of the Lucky\nBoy vein will intersect the hanging-wall of the west fault. Another factor which possibly\naffected mineralization in the locality of this property, as compared with the locality of the\nDunwell veins, is the location of the Glacier Creek veins in a higher horizon of the sediments\nabove the underlying and southerly-plunging Ben Ali stock. Suggestive of this is a generally\nless intense alteration and silicification of the argillite in the lower elevations of the hill\nwhich comprise the Glacier Creek property. Valley-glacier erosion has also more intensively\naffected the Glacier Creek valley as compared with the Bear River slope of the \" Dunwell \"\nhill. Exposures of the veins in the adits show no evidence of oxidation, leaching, or secondary\nenrichment; because of the small amount of back above the adits, it is not probable that this\ncondition would alter materially towards the surface.\nA feature of the area is the number of more or less parallel quartz veins varying from a\nfew inches to several feet in width. Where exposed on the surface and in the underground\nworkings they contain very little mineral. The best mineralization observed on the property\nis exposed in the main adit at approximately 830 feet elevation, along the 1935 north and\nsouth drifts, and also in the Lucky Boy vein.\nThree adits explore the ground, the main crosscut adit at 830 feet elevation; the \" Little\nWonder\" adit at 780 feet elevation; and a short adit on the O.K. Fraction at 670 feet\nelevation. A small amount of trenching was also done several years ago, but these surface\nworkings are caved and overgrown with brush.\nThe portal of the main crosscut adit at 830 feet elevation is about 370 feet lower than the\nDunwell No. 4 adit, and is located in the creek-canyon of the west fault, on its east side and\nabout 90 feet from the creek. It is driven south 75 degrees east for 618 feet, thence south\n82 degrees east for 177 feet to the north and south drifts. The formation is a series of bedded\nargillaceous sediments striking north 40 degrees west and dipping 70 degrees south-westerly.\nA grey lamprophyre dyke 3 feet wide cuts the formation at 480 feet from the portal and at\n540 feet from the portal a feldspar porphyry dyke is intersected.\nAt 180 feet from the portal a reticulated and brecciated zone of quartz stringers 5 feet\nwide, sparingly mineralized with pyrite, is intersected. This strikes northerly and dips\nwesterly at 45 degrees. NORTH-WESTERN DISTRICT (No. 1). B 15\nAt 330 feet from the portal the crosscut intersects a zone of barren and brecciated quartz\nstringers and bands across a width of from 4 to 5 feet. This strikes northerly and dips\n70 degrees westerly and constitutes the so-called \" Central \" vein. A drift has been driven\nnorth on it for 120 feet. In the face of this drift, the zone 6 feet wide strikes north 18\ndegrees west, dips 50 degrees west, and is composed of barren quartz stringers % to 6 inches\nwide.\nAt 390 feet from the portal a well-defined quartz vein 10 inches wide, containing some\npyrite, is intersected. At 470 feet from the portal the hanging-wall of a barren crushed\nzone 27 feet wide is intersected. This strikes north 10 degrees east, dips 60 degrees westerly,\nand is composed of crushed argillite and dyke-matter with quartz and calcite stringers and\nveinlets mainly on the hanging- and foot-wall sides. A winding drift and crosscut for 57 feet\nin a north to north-westerly direction commencing on the foot-wall of this zone exposes\ncrushed argillite with brecciated quartz and calcite stringers across a width of 4 to 4.5 feet,\nwith no evident sulphide mineralization. In places the quartz-calcite gangue shows patches\nof light greenish coloration from a finely-disseminated nickel-chromium silicate, on account\nof which this zone is locally named the \" Green \" vein. At 57 feet from the crosscut, the\n\" Green \" vein drift turns to a bearing of north 10 degrees east and continues along the\nhanging-wall of the zone for 63 feet to the face. The face is turned to a bearing of north\n7 degrees west and exposes a few stringers of quartz and calcite, mineralized very sparingly\nwith pyrite and dipping 60 degrees west in crushed argillite.\nAt 795 feet from the portal, the crosscut intersects an irregular and brecciated quartzose\nzone 4 to 6 feet wide, generally sparingly mineralized with blebs, stringers, and sparse dissemination of pyrite, sphalerite, and galena, striking about north 20 degrees west, and dipping\n30 degrees westerly. A drift south 20 degrees east for 51 feet appears to favour the\nhanging-wall side of this zone and exposes quartz stringers and pyritized argillite. The\nfollowing samples were taken in the south drift:\u00E2\u0080\u0094\n(1.) Selected sample of the best mineralization: Gold, 0.06 oz. per ton; silver, 0.08 oz.\nper ton; lead, nil; zinc, 2 per cent.\n(2.) Muck from the south-drift face: Gold, trace; silver, 0.3 oz. per ton; lead, nil;\nzinc, trace.\nA winding northerly drift has been driven along this zone for 198 feet, commencing with\na bearing of north 22 degrees east for 39 feet, and varying for the remainder of its length\nbetween north 43 degrees west, north 20 degrees east, and north 4 degrees west at the face.\nIt appears to favour the foot-wall and exposes irregular quartz bands, stringers, and patches,\nirregularly and sparingly mineralized with pyrite, sphalerite, and galena. At 39 feet from\nthe commencement of this north drift a crosscut south 70 degrees west for 15 feet through\nthe zone exposes the best mineralization. A sample for 12 feet along the walls and including\nthe face of this crosscut assayed: Gold, 0.08 oz. per ton; silver, 1 oz. per ton; lead, nil;\nzinc, 4 per cent. A selected sample of the best mineralization contained in the quartz bands\nand stringers along the north drift assayed: Gold, 0.20 oz. per ton; silver, 5.6 oz. per ton;\nlead, 4 per cent.; zinc, 4 per cent.\nFrom the face of this main adit to the boundary of the Victory and Barney claims is\nabout 540 feet. At about 300 feet northerly from the present face of the north drift, the\nboundary of the George E. claim of the Dunwell property would be crossed. At about 300\nfeet southerly from its present face the south drift would break through to the surface.\nWhere the north and south drifts start from the adit the vertical back is about 75 feet. Along\nthe easterly projection of the adit towards the Barney claim the surface slopes upward at\n15 degrees. On account of these factors, further development in the Glacier Creek Company\nground from this adit is comparatively limited. On the other hand, it would offer a convenient site for further depth exploration of the George E. showings of the Dunwell company,\nin the favourable location of their intersection with the foot-wall of the west fault. By\nextension of the Glacier Creek north drift from the adit towards the George E. workings for\na further distance of about 800 feet the vein would be explored further in this direction, and\na back of about 200 feet would be developed below the old George E. adit on the east side\nof the creek.\nAt 780 feet elevation, and about 1,050 feet southerly from the portal of the main adit,\nthe \" Little Wonder \" adit is located on the west side of the draw of the east fault. The adit\nis a crosscut driven along a bearing of north 45 degrees west in argillite striking north 15 B 16 REPORT OF THE MINISTER OF MINES, 1937.\ndegrees east and dipping 70 degrees westerly. At about 260 feet it intersects a sheared and\ncrushed zone with some bands and stringers of brecciated quartz and argillite striking north\nand dipping 70 degrees west. This is drifted on to the north for about 500 feet, and with\nthe exception of two short lenticular quartz bands well-mineralized with pyrite, sphalerite,\nand galena, it is mainly composed of crushed argillite. The face of the drift exposes the\nhanging-wall of the zone striking north 5 degrees east and dipping 70 degrees westerly. A\ncrosscut to the east would intersect the foot-wall and explore the full width of the zone. The\nhanging-wall side of the zone exposed in the face is composed of brecciated argillite with\nquartz bands and stringers very sparingly mineralized with mainly pyrite. The best mineralization observed occurs in a lenticular quartz band 2 to 18 inches wide starting 90 feet south of\nthe face. Of this, the first 30 feet of length in the adit-floor is well-mineralized across a\nwidth of 10 inches. A composite sample of this length (30 feet) across 10 inches in the\nadit-floor assayed: Gold, 0.28 oz. per ton; silver, 4.6 oz. per ton; lead, 6 per cent.; zinc,\n8 per cent. In a small stope 15 feet long and 10 feet high in the roof of the adit a well-\nmineralized lenticular quartz band pinching out at both ends in crushed argillite is exposed.\nA composite sample of this lens in the roof of the stope assayed: Gold, 1.84 oz. per ton; silver,\n4 oz. per ton; lead, 5 per cent.; zinc, 6 per cent.\nA raise reported to be 65 feet high connects this drift with an upper adit reported to be\n120 feet long. The latter is also connected with the surface by a raise. The raise to the\nupper adit is in a dangerous condition and inaccessible for examination. The portal of the\nupper adit could not be located and has probably caved. The raise from the upper adit to\nthe surface was located amongst the dense underbrush, unguarded, dangerously open, partly\ncaving, and inaccessible for examination. A back of about 110 feet is estimated from the face\nof the lower adit-drift to the surface.\nAt the portal of the lower \" Little Wonder \" adit three dumps of vein-material mineralized\nwith pyrite, sphalerite, and galena, estimated to contain 1, 3, and 15 tons each, have been\naccumulated. It has not been ascertained from what part or parts of the \" Little Wonder \"\nworkings this material originated. A composite sample of these dumps assayed: Gold, 0.56\noz. per ton; silver, 2.8 oz. per ton; lead, 5 per cent.; zinc, 6 per cent.\nAt an elevation of 670 feet, 100 feet above Glacier Creek and about 400 feet south of\nthe \" Little Wonder \" adit, a practically barren, brecciated, and reticulated quartz zone, 10\nfeet wide on the hanging-wall of a felsite dyke, outcrops in argillite on the face of a bluff\non the west side of the draw of the east fault. This zone strikes north 5 degrees east and\ndips 55 degrees westerly, and may possibly be correlated with the zone in the \" Little\nWonder \" adit. An adit 60 feet long has been driven on it.\nAt an elevation of 560 feet, about 100 feet above the bed of Glacier Creek and about\n1,400 feet south-west from the \" Little Wonder\" adit, the Lucky Boy vein outcrops in\nargillite for about 20 feet above the brink of Glacier Creek canyon. This vein is 2.5 feet\nwide, strikes north 30 degrees west and dips 35 degrees south-west. Continuity at both ends\nis obscured by overburden. For about 15 feet of its exposed length the vein is mineralized\nwith massive, fine-grained galena and sphalerite across a width of 18 inches, with 12 inches\nof fair mineralization in a quartz gangue on the hanging-wall. A sample of the 18 inches\nof solid mineralization assayed: Gold, 0.06 oz. per ton; silver, 23.5 oz. per ton; lead, 58\nper cent.; zinc, 16 per cent. A sample of the siliceous material on the hanging-wall across\n12 inches assayed: Gold, 0.06 oz. per ton; silver, 7 oz. per ton; lead, 4 per cent.; zinc, 6\nper cent.\nThis company was incorporated in British Columbia on April 4th, 1924, with\nLakeview Mines, registered office at 101 Pemberton Building, Victoria. It has a capitalization\nLtd. (N.P.L.). of $1,000,000, divided into 4,000,000 shares of 25 cents par value, of which\n2,743,828 shares are reported to be issued. The holdings consist of Lake-\nview No. 1, No. 2, No. 3, and Silver Bell Fraction Crown-granted mineral claims, totalling\n158.17 acres, on which taxes have been paid to December 31st, 1937. The property is located\non the north side of Glacier Creek, east of the Dunwell holdings, at elevations ranging from\nabout 2,000 to 3,000 feet above sea-level.\nThe property is reached by the Stewart-Bear River Motor-road from Stewart dock to\nthe Glacier Creek bridge at 200 feet elevation, a distance of 5% miles.

The main (\" Cabin \") vein has a general northwesterly strike and dips about 60 degrees south-westerly. It outcrops in a creek-bed immediately south of the old camp at 2,190 feet elevation. Several years ago a section of this\nvein was stripped and open-cut for about 100 feet and a shaft sunk in the hanging-wall. In\n1928 the shaft was unwatered and crosscuts were driven to the vein at depths of 25 and\n45 feet from the collar. The upper crosscut is reported to have intersected promising\nmineralization, consisting of galena, sphalerite, chalcopyrite, and pyrite, but the vein is\nreported not to be so well mineralized in the lower crosscut. In the open-cut the vein strikes\nnorth 72 degrees west and dips 68 degrees south-westerly -It is from 2 to 4.8 feet wide, and\nis generally mineralized with pyrite, galena, and sphalerite in a quartz-gangue, with a streak\nof massive galena and sphalerite mineralization 10 inches wide on the foot-wall. About\n1925 a long adit was driven with the objective of intersecting the vein at a depth of 250\nfeet below the collar of this shaft. Several narrow veins and stringers were cut in this\nworking, and at 760 feet from the portal a vein was intersected, striking north 71 degrees\nwest and dipping from 82 degrees north-easterly to vertical. A drift west for 75 feet exposes\nerratic, sparsely-mineralized quartz-lenses 12 to 16 inches wide in argillite on the south side\nof a felsite dyke.

This\nexposes a well-defined mineralized shear 8 to 10 feet wide containing siliceous lenses, pockets,\nand stringers well mineralized in places with galena, sphalerite, pyrite, and tetrahedrite\nacross widths of several inches. From these a small tonnage of high-grade ore is reported by\nlessees to have been shipped several years ago by McKay.\nAbout 300 feet south of these workings and at 95 feet lower elevation, the old\n\" Campbell \" adit extends north for 262 feet. At 187 feet from the portal a crosscut to the\nwest intersects a vein at 60 feet. A drift extends westerly along this vein for 250 feet, with\na winze at 112 feet from the face and a raise for about 25 feet at 165 feet from the face,\nreported to have been driven in 1928. East of the intersection in the crosscut the vein appears\nto be faulted or dragged. Along the drift the vein is 14 inches to 4 feet in width, lenticular\nand consists of quartz with generally sparse sulphide mineralization. At its easterly end,\nin the vicinity of the crosscut, it appears to be appreciably shattered and resolves into a series\nof barren quartz stringers and lenses. At the intersection by the crosscut the vein strikes\nnorth 43 degrees west and dips 40 to 50 degrees south-westerly. At 90 feet from the crosscut\nand in the vicinity of the raise it is joined by another vein and continues along the drift to\nthe face striking north 57 degrees west, dipping 50 degrees south-westerly, and adjacent to\nand associated with grey lamprophyre dyke. The best mineralization commences at about\n75 feet west of the crosscut in the vicinity of the junction of the two veins and continues\nfor about 60 feet to slightly west of the winze. Of this length about 55 feet is fairly well\nmineralized with galena, sphalerite, pyrite, and some tetrahedrite across widths of from 20\ninches to 4 feet. Beyond this to the face the vein-fissure is erratic, not so well defined and\nfilled mostly with dyke material and some quartz stringers. The winze 112 feet from the\nface was flooded and could not be examined.\nAbout 400 feet north-easterly from the old \" McKay \" cut and about 100 feet higher\nthere is an old shaft, short adit, and open-cut on a reticulated and brecciated quartz vein\n12 feet wide, striking easterly in argillite. In this, some quartz stringers and streaks carrying galena and pyrite are to be seen. It is reported by lessees working on the property that\nsome high gold assays were obtained from this showing by \" old-timers \" and that about 21\ntons of ore was shipped. This vein is in alignment with a cross-vein 10 feet wide, exposed\nby shallow stripping adjacent to the \" McKay \" cut and mineralized with pyrite, sphalerite,\nand some galena. To establish continuity and correlation of these two exposures interval\ntrenching would be required. The cross-vein adjacent to the \" McKay\" cut strikes east\nand dips 70 degrees north, and a chip sample across 10 feet assayed: Gold, 0.05 oz. per ton;\nsilver, 10.6 oz. per ton; lead, nil; zinc, 1.5 per cent.\nSince about 1933 the property has been operated intermittently by lessees, and further\nexploration in the effort to extract ore of shipping-grade resulted in the first shipment from\nthis operation of about 13 tons, reported by H. D. Rochfort, one of the lessees, to assay about:\nGold, 0.32 oz. per ton; silver, 167 oz. per ton; lead, 18 per cent. This ore came from a\nquartz vein about 50 feet easterly from the old \" McKay \" cut, where a lens 12 to 18 inches\nwide, well mineralized with galena, pyrite, and tetrahedrite in a quartz vein up to 4 feet\nwide, was stripped and open-cut for about 30 feet. This vein strikes north 70 degrees west\nand dips from 50 to 60 degrees south-westerly.\nWork by these lessees was also carried out at that time on the main (\" Cabin \") vein in\nthe open-cut at 2,190 feet elevation. From this locality a shipment of about 10 tons is reported\nby H. D. Rochfort to have assayed about: Gold, 0.12 oz. per ton; silver, 62 oz. per ton;\nlead, 12.9 per cent.\nA sample taken by the writer in 1934 across 10 inches of the foot-wall streak in the\nmain (\"Cabin\") vein open-cut assayed: Gold, 0.02 oz. per ton; silver, 20.15 oz. per ton;\nlead, 15 per cent.; zinc, 15 per cent. A sample of the hanging-wall side adjacent to this\nacross 4 feet assayed: Gold, 0.04 oz. per ton; silver, 10.5 oz. per ton; lead, nil; zinc, 3 per\ncent. Subsequent work by lessees on the main (\" Cabin \") vein has centered on the extension\nof the open-cut for a total length of 137 feet and a drift east on the vein from the floor of the\ncut for 73 feet. Resultant from this work 10 tons shipped to the Dunwell mill is reported by\nH. D. Rochfort to have assayed about: Gold, 0.16 oz. per ton; silver, 40 oz. per ton; lead,\n15 per cent. A further shipment of about 45 tons to the Dunwell mill from the main NORTH-WESTERN DISTRICT (No. 1). B 19\n(\"Cabin\") vein is reported by H. D. Rochfort to have assayed about: Gold, 0.12 oz. per\nton; silver, 52.5 oz. per ton; lead, 12 per cent.\nOn August 25th, 1937, two dumps of broken ore, estimated to contain about 20 tons each,\nwere accumulated at the main (\" Cabin \") vein workings. An average sample of the dump\nat the end of the \" Cabin \" adit track assayed: Gold, 0.04 oz. per ton; silver, 33 oz. per ton;\ncopper, trace; lead, 7.1 per cent.; zinc, 7.8 per cent. The other dump in the vicinity of the\ncabin was composed of vein-material with similar mineralization to this.\nRecent leasing operations were also carried out in the \" McKay \" cut. A shipment of\n6.96 dry tons by A. Cameron, Stewart, to the Prince Rupert sampling plant, reported to be\nfrom this locality, assayed: Gold, 0.08 oz. per ton; silver, 30.2 oz. per ton; copper, 0.1 per\ncent.; lead, 8 per cent.; zinc, 4.2 per cent.; silica, 28 per cent.; iron, 23.5 per cent.; lime,\n0.2 per cent.; sulphur, 27 per cent.; arsenic, 0.2 per cent.; antimony, nil.\nIn August, 1937, exploratory development-work was being done by H. D. Rochfort and\none man in the \" Campbell \" adit at 2,125 feet elevation. In this working a section of well-\nmineralized vein-material about 9 feet west of the raise was being stoped from the drift-back\nwith the object of accumulating shipping-grade ore. The stope had advanced for a length\nof 10.3 feet and a height of 3 feet above the drift-back. In this section the vein is 3.3 feet\nwide and fairly well mineralized with pyrite, sphalerite, tetrahedrite, and some galena, with\na well-mineralized streak 7.2 inches wide on the hanging-wall. A sample of the vein in the\nstope-back across 3.3 feet assayed: Gold, 0.10 oz. per ton; silver, 40 oz. per ton; copper, nil;\nlead, 0.4 per cent.; zinc, 2.3 per cent. A sample of the hanging-wall streak across 7.2 inches\nassayed: Gold, 0.30 oz. per ton; silver, 45 oz. per ton; copper, trace; lead, 0.6 per cent.;\nzinc, 4.7 per cent.\nThe following additional samples were taken in this drift:\u00E2\u0080\u0094\n(1.) North side, 8.4- feet west of raise, across 1 foot of the vein on the hanging-wall,\nplus 0.6 foot on the foot-wall, assayed: Gold, 0.06 oz. per ton; silver, 16 oz. per ton; copper,\nnil; lead, 0.2 per cent.; zinc, 0.4 per cent.\n(2.) At site of (1), 8 inches of mainly pyrite on the foot-wall assayed: Gold, 0.06 oz.\nper ton; silver, 15 oz. per ton; copper, nil; lead, 0.4 per cent.; zinc, 0.2 per cent.\n(3.) South side, opposite raise, across 2.6 feet, assayed: Gold, 0.02 oz. per ton; silver,\n0.1 oz. per ton; copper, nil; lead, nil; zinc, trace.\n(4.) North side, 4 feet east of raise, across 3.4 feet of sparsely-mineralized quartz and\ncalcite assayed: Gold, trace; silver, 0.8 oz. per ton; copper, nil; zinc, trace; lead, 0.2 per\ncent.\n(5.) North side, 15 feet west of stope, across 3.6 feet of silicified argillite and dyke with\nquartz stringers and disseminated pyrite, assayed: Gold, trace; silver, 5.5 oz. per ton;\ncopper, nil; lead, 0.2 per cent.; zinc, 0.3 per cent.\n(6.) At site of (5), 2 inches of mineralization in a streak on the hanging-wall assayed:\nGold, trace; silver, 9 oz. per ton; copper, 0.2 per cent.; lead, nil; zinc, nil.\nThese samples and assays represent the best-defined and mineralized section of the vein\nobserved in the \" Campbell \" adit.\nRecent work had also been done in the main (\" Cabin \") vein open-cut and adit at an\nelevation of 2,190 feet. This had been centered mainly in the driving of the \" Cabin \" vein\nadit as a drift south-easterly, starting from the bottom of the cut and extending for 73 feet\nto the face. This adit is timbered at the portal for a length of 12 feet with no back for this\nlength. Along the drift the back increases to about 10 feet at the face. Projected for\n12 feet ahead of this adit face, the back to the floor of the cut would increase to 15.5 feet.\nAt about 17 feet beyond the adit face, the face of the open-cut rises to give a projected back\nat this point of 20.5 feet to the surface. Easterly from this point for a distance of about 400\nfeet along the strike of the vein, there is an increasing surface-gradient of only 20 per cent.,\nwhich does not permit the attainment of any appreciable back at the horizon of the \" Cabin \"\nvein adit. It should also be noted that taking into consideration the strike and dip of the\n\" Cabin \" and \" McKay \" veins, and their relation to the topography, these two exposures\ncannot be correlated definitely. In this respect, however, the possibility of a cross-fault\nbetween these workings as indicated in the \" Campbell \" adit, should be considered.\nIn the \" Cabin \" vein drift the vein is well-defined and generally well-mineralized. Starting at 12 feet from the portal and extending for 60 feet along the drift, a band of massive B 20\nREPORT OF THE MINISTER OF MINES, 1937.\ngalena and sphalerite mineralization 0.5 to 8.2 inches wide and averaging 4.5 inches in width,\noccurs on the hanging-wall. The vein shows shearing and the walls are generally well-\ndefined with a development of gouge, especially on the hanging-wall. In the face of the adit\nthe fissure filling is composed of reticulated quartz veins and stringers and sheared formation\n4.6 feet wide with streaks, veinlets, and patches of pyrite, galena, and sphalerite. A sample\nin the face, across 4.6 feet, assayed: Gold, trace; silver, 12 oz. per ton; copper, 0.4 per cent.;\nlead, 4.2 per cent.; zinc, 4.5 per cent. A sample across 2 feet, 41 feet from the portal,\nassayed: Gold, 0.08 oz. per ton; silver, 5.6 oz. per ton; copper, 0.2 per cent.; lead, 4.2 per\ncent.; zinc, 4.5 per cent. A composite sample of the hanging-wall band in the \" Cabin \" adit\nfor a length of 45 feet and an average width of 4.5 inches, commencing at 6 feet from the\nface, assayed: Gold, 0.04 oz. per ton; silver, 37.5 oz. per ton; copper, 0.8 per cent.; lead,\n8.5 per cent.; zinc, 10.5 per cent.\nSurface continuity of the \" Cabin \" vein beyond the limits of the open-cut has not been\ndefinitely established. About 137 feet south-easterly a trench exposes an undelimited width\nof 6 inches of mineralized and oxidized quartz, assaying: Gold, 0.10 oz. per ton; silver, 6 oz.\nper ton; copper, trace; lead, 0.5 per cent.; zinc, 0.5 per cent.\nFor further exploration of the showings on this property more stripping, trenching, and\nopen-cutting is required to establish surface continuity and possible correlation of the \"Cabin\"\nand \" McKay \" showings in the interval between these workings. Surface continuity of the\n\" Cabin \" vein to the west of the \" Cabin \" workings and of the \" McKay \" vein to the east of\nthe \" McKay \" workings could also be investigated by means of stripping, trenching, and\nopen-cutting. Interval trenching, stripping, and open-cutting between the \" McKay \" workings and the old shaft at 2,300 feet elevation, 550 feet north-easterly, could also be done to\nestablish the possible correlation of the cross-structure at the \" McKay \" workings with the\nstructure at the old shaft.\nBased on the dip of the \" Cabin \" vein as exposed in the \" Cabin \" vein surface workings,\nit is improbable that the vein in the drift off the long crosscut at 1,945 feet elevation can be\ncorrelated with this. On the other hand, depth-projection of the \" Cabin \" vein and strike-\ncorrelation indicates its possible relationship with the third structure, 162 feet southerly of\nthe drift. Between these two levels is a vertical back of 237 feet and vein-back of 313 feet.\nA raise on this structure from the main crosscut adit to the \" Cabin \" vein shaft would\ndetermine possible correlation between the two veins, establish possible depth-continuity of\nthe \" Cabin \" vein, and would also explore two possible vein-intersection areas indicated as\npossibly occurring at about 100 and 194 feet along the projection of the raise. Any encouraging mineralization encountered in this work would require additional exploration by sub-level\ndrifting.\nFrom the \" Campbell \" adit workings, the continuation of the raise and sub-levelling\nfrom it would not only further explore the continuity of the mineralization in this section of\nthis vein, but would also establish some clarity in structural relationship between this vein,\nthe exposures in the \" McKay \" workings, and the possibly intersecting fault.\nThe results so far achieved by exploration of the property indicate that the objective of\nfurther exploration would be the possibility of indicating and proving a sufficient tonnage of\nmilling-grade silver-lead-zinc ore to warrant mill-concentrator construction.\nThe grade of mineralization exposed on the property by exploration to the present time\ndoes not indicate the possibility for accumulation of any appreciable quantity of shipping-\ngrade ore to assist appreciably in defraying the cost of further preliminary exploration.\nAmerican Creek Area, Stewart, Portland Canal.\nThis company was incorporated in British Columbia in 1930, to take over\nNorth-Western the properties of the North-Western Prospectors Syndicate.

From this point a tractor-trail extends up the west side of American Creek for\nabout 3% miles to the \" Mountain Boy \" ridge at about 1,000 feet elevation. At this point a\ntrail gradually descends to the moraine and slide-covered valley-bottom at about 800 feet\nelevation, along which it continues for about 2 miles and then ascends the timbered bench to\nthe old American Mining and Milling cabin at about 1,200 feet elevation.

With the rapid recession\nof the glacier this route has become impassable. At the present time the route crosses\nAmerican Creek to its east side at the foot of the glacier, and the trail continues up the steep\nsouth rock-slope of the bluffy ridge buttressing the glacier-front, and locally termed \" The\nPimple.\" This is ascended by a series of short and very steep switchbacks to an elevation\nof 3,800 feet, a distance of about 1% miles. From this point the trail gradually descends\nthe north slope of \" The Pimple \" to the valley-bottom at 3,200 feet elevation, a distance of\nIVz miles. At this point American Creek is crossed to its west side and a course of least\nresistance is followed, through the rocky and heavy talus-covered west flank of the valley-\ntrough, to the tent-camp at 3,500 feet elevation on the Camp claim.\nIn 1936, in the effort to avoid the ascent of \" The Pimple,\" a trail was constructed along\nthe east edge of American Creek glacier at the foot of the west slope of \" The Pimple.\"\nThis has now become impassable on account of extensive Assuring and rock-sloughing.\nThe rock formations in the locality of the claims consist of sediments and volcanics of\nthe Lower Hazel ton group (Bitter Creek and Bear River series). Black calcareous argillites,\nargillaceous limestone, sandy argillite, and quartzite of the Bitter Creek series outcrop for\na length of about 5 miles along the lower slopes up to about 500 feet above the valley-floor in\nan anticline plunging at the north and south ends beneath the Bear River Series volcanics.\nThe volcanics of the higher elevations comprise tuffaceous beds at the base of the series,\nimmediately overlying and transitional from the argillite. Above these is a complex of greenstone, in places schistose, and fine and coarse textured breccias. Rocks of porphyritic texture\noutcrop in irregular areas of the higher elevations and are possibly of intrusive origin. Light\nand dark coloured dykes intrude the sediments and volcanics.\nThe main mineral-showings are of four different structural and mineralogical types, and\nin the following text the letters A, B, C, D, E, F, G, and H refer to the showings as are\nindicated on the accompanying map:\u00E2\u0080\u0094\n(1.)

A, B, and H: Quartz replacement in a wide fracture-zone striking northerly along\nthe margin of the sediments and volcanics and adjacent to porphyritic rock, sparsely mineralized in places with pyrite, some sphalerite, and galena, and in one transverse quartz-\ncalcite stringer (B) with spectacular pockets of native gold.\n(4.) F and G: Siliceous replacement in sheared greenstone, mineralized with sphalerite,\ngalena, and pyrite, striking north-westerly and dipping south-westerly.\nThe claims have not been prospected in detail, and since the examination of the property ,\nby the writer other mineralized showings are reported by the management to have been discovered. In the following text the showings are described from the lowest to the highest\nelevation.\nAt 3,400 feet elevation (E) on the Moonlight No. 1 in the rock-knolled area bordering\nthe west side of the valley-bottom three quartz stringers, 1 to 3 inches wide, mineralized in\nplaces with blebs and patches of tetrahedrite, galena, and chalcopyrite, outcrop in bands of\ntuff. Some work has been done on a quartz stringer 1 to 2 inches wide outcropping in a\nlenticular band of limy tuff about 30 feet wide between narrow beds of calcareous argillite.\nThe argillite strikes north 27 degrees east and dips 40 degrees north-westerly. On the east\nside of the valley the sediments strike northerly and dip 40 degrees easterly. The quartz\nstringer strikes north 21 degrees east and dips 45 degrees north-westerly. It has been traced\nabout 100 feet by three shallow open-cuts and two open-cuts 4 feet deep and 50 feet apart. A\ncombined sample of the stringer in the bottom of the two deep cuts across a width of 1.5\ninches, mineralized with some tetrahedrite, pyrite, and galena, assayed: Gold, trace; silver,\n71.2 oz. per ton. A sample across 3 inches of pyritized tuff on the hanging-wall assayed:\nGold, nil; silver, 1 oz. per ton. During the 1935 season several sacks of sorted high-grade\nore from these stringers were shipped. NORTH-WESTERN DISTRICT (No. 1). B 23\nAt an elevation of 3,900 feet, a limy tuff-bed (C), mineralized with galena, tetrahedrite, some\nsphalerite, pyrite, and chalcopyrite, occurs slightly west of and just above a vertical bluff\nthat marks the crest of the underlying argillite. Adjacent and paralleling the tuff-bed on\nthe east is a bluffed ridge of porphyritic rock. The mineralized bed occupies the gently-\nsloping depression between the argillite bluff and the porphyry bluffs. The tuff-bed is\nappreciably oxidized, the iron oxide resulting mainly from siderite or ankerite. It has been\ntraced for about 270 feet by natural exposure and a series of small open-cuts and \" pop-\nholes,\" and is best exposed up to a width of 11.4 feet along 80 feet of its southerly section.\nIn this section a streak 1 to 10 inches wide of fairly solid galena with tetrahedrite, sphalerite,\nand chalcopyrite occurs on both the hanging- and foot-wall, with some cross-veinlets and blebs\nof mineralization extending into the central portion of the bed. A sample of selected mineralization from the hanging- and foot-wall streak 1 to 10 inches wide along the southerly 80\nfeet of the exposure assayed: Gold, 0.04 oz. per ton; silver, 147 oz. per ton; copper, 1 per\ncent.; lead, 56.4 per cent.; zinc, 2.3 per cent. To the north the possible continuity is obscured\nby talus. To the south, overburden obscures the possible continuity. Further continuity in\nthis direction is possibly prevented by a probable transverse fault striking north 51 degrees\neast. This is marked by a deep canyon in the argillite to the north-east and a defined depression in the direction of its south-westerly projection in the volcanics. In the bluffs of the\nnorth side of the canyon several lamprophyre dykes outcrop, and the fault is further indicated\nby their abrupt termination and absence in the argillite of the south bluff.\nAt about an elevation of 3,850 feet and 150 feet southerly of the last exposure of (C) a\nbrecciated quartz vein (D), mineralized with resinous sphalerite, galena, and chalcopyrite,\noutcrops in argillite along the face of the steep bluff. This was inaccessible for detailed\nexamination, but it is reported by the management to have been traced towards the south for\nabout 150 feet, where it tapers to 2 inches in width and appears to die.\nAt 4,000 feet elevation and 750 feet northerly from (C) a quartz-replacement zone (A),.\n50 to 75 feet wide, outcrops in the sediments and volcanics of the Bear River Series adjacent\nto and westerly of the argillite. Comparatively unaltered sections of the zone suggest replacement in a porphyritic rock that may be intrusive into the sediments. The zone is exposed\nalong a hummocky bench which in places is faced on its east side with abrupt vertical bluffs\nextending above the adjacent sediments. It strikes north 21 degrees east and appears to dip\nsteeply westerly into the hill. To the north from this point it can be traced by natural\nexposure for a distance of about 2,500 feet. The continuation of the zone to the south can\nbe seen but was not examined. The zone consists of a network of quartz veins, patches, and\nstringers, with intervening partly-replaced areas. From the main body many quartz veinlets\nand stringers strike at acute angles into the hanging- and foot-walls. In places these lateral\nstringers constitute a network of appreciable width. The rock between the stringers and\nquartz bands is generally sparsely mineralized with disseminated pyrite. The quartz of the\nzone is generally \" vuggy \" or cellular and barren, but a sparse mineralization with pyrite\nand sphalerite was seen in two small sections. With the exception of a few small \" pop-\nholes \" no work has been done on the main zone. A sample of selected mineralization from\ntwo \" pop-holes \" in the central section of the zone, showing sparse mineralization of pyrite\nwith some sphalerite and tetrahedrite, assayed: Gold, trace; silver, 32 oz. per ton. A chip\nsample across a width of 30 feet of the zone towards its north end assayed: Gold, trace;\nsilver, 0.04 oz. per ton. For preliminary prospecting and sampling of this zone, a series of\ntransverse open-cuts 3 to 4 feet deep would be required.\nAt 4,080 feet, on the south side of a creek-gulch, spectacular pockets of crystalline,\narborescent native gold, were discovered in 1936 in a lateral quartz-calcite stringer (B)\nbranching from the main replacement-zone (A) on its hanging-wall side and outcropping\nin the face of a small bluff flanking the creek-trough. Three stringers 1 to 4 inches wide,\n4 and 15 to 20 feet apart, striking north 16 degrees east and dipping steeply westerly, outcrop\nin the calcareous tuff of the bluff face. The gold occurs in the central stringer in its exposure\nin the bluff face between 4,080 feet elevation, 20 feet above the talus and snow-filled creek-\nbottom, and 4,140 feet elevation at the crest of the bluff. From the crest of the bluff the\nstringer, 1 to 5 inches wide, can be traced southerly for 50 feet towards the main zone, where\nit appears to pinch out. Beyond this to the south other stringers outcrop but cannot be\ndefinitely correlated with the gold-bearing one. To the north, towards the creek, continuity B 24\nREPORT OF THE MINISTER OF MINES, 1937.\nis obscured by talus and snow in the creek-trough. In the rock bluff on the north side of the\ncreek the stringer has not been located. In the bluff face on the south side of the creek and\njust above the talus-slope, the stringer has been opened up by a main open-cut 6 feet wide and\nabout 12 feet long, and in this cut the most spectacular gold-pockets were discovered. Above\nthis and about 15 feet apart two smaller cuts have also been excavated. In the main cut on\nAugust 18th the stringer was % to 1% inches in width, and consisted of calcite and \" vuggy \"\nor honeycomb quartz with sparse mineralization, mainly in the calcite, of galena cubes % inch\nin diameter, sphalerite, chalcopyrite, and an occasional small branch of arborescent gold.\nThe wall-rock for about 10 inches bordering the stringer showed silicification and disseminated pyrite. A sample of the stringer in the face of the cut, across a width of 1 inch\nand a height of 3 feet, assayed: Gold, 3.10 oz. per ton; silver, 6 oz. per ton. A sample\nacross 8 inches of the hanging-wall, showing silicification and disseminated pyrite, assayed:\nGold, trace; silver, 0.2 oz. per ton.\nIn late August, 1937, 61.378 dry pounds of selected vein-material from this showing (B)\nwas shipped to the Trail smelter and returned an assay of 387.7975 oz. gold per ton and\n164.4 oz. silver per ton. An additional lot of selected high-grade material weighing 55.575\ntroy ounces was also shipped to Trail and treated as bullion. This was fluxed and melted,\nand yielded 9.825 oz. of bullion of a fineness of 667.43 parts gold and 287.6 parts silver. Subsequent to the above shipments, additional selected high-grade gold ore is reported by the\nmanagement to have been mined from the stringer.\nAt 4,100 feet elevation and about 1,500 feet northerly of (B) a band of quartz and\nsiliceous replacement (H), 3 feet wide, mineralized with pyrite, occurs in an outcrop of porphyritic rock. The band strikes north 21 degrees east, parallel to the zone (A) the dip is\nnot clear, and it can be traced for only about 20 feet, continuity in both directions being\nobscured by talus.\nTraversing north-westerly from (H), a wide belt of coarse and fine breccias is crossed to\nabout 5,000 feet elevation. North-westerly from this, sheared greenstones form the bluffs\nof the range-crest and extend to the extensive glacier which blankets the summit.\nAt 5,100 feet elevation on the Northern No. 7, about 1,725 feet north-westerly from (H),\na quartz-replacement zone (F) in sheared greenstone, mineralized with streaks and blebs of\nresinous sphalerite, some galena and pyrite across 9 feet, outcrops at the base of a vertical\nbluff. The attitude of the zone is not clear, but it appears to strike north 39 degrees west and\ndip steeply south-westerly. To the south-east the possible continuity is obscured by talus,\nand towards the north-west the vertical bluff face does not permit examination.\nAt the crest of the bluff, between 5,260 and 5,270 feet elevation and about 225 feet northwesterly from (F), three open-cuts (G) along a distance of 60 feet expose a zone with\nmineralization across 4, 5, and 17 feet, similar to that seen at (F), in sheared greenstone.\nIn these cuts the mineralized zone strikes north 49 degrees west, but the dip is not clear. A\ncomposite chip sample from the three open-cuts, representing an aggregate width of 9 feet,\nassayed: Gold, trace; silver, 14 oz. per ton; copper, trace; lead, 1 per cent.; zinc, 4.2 per\ncent. The zone can be traced from near the edge of the bluff at its south-east extremity to\n20 feet north-westerly of the most westerly cut, a total distance of 80 feet. At its northwesterly end it is not so well defined. This zone cannot be definitely correlated with the\nshowing (F) at the foot of the bluff from which it is offset to the north. Continuity to the\nsouth-east is prevented by the inaccessible bluff face and to the north-west is obscured by\ntalus and the adjacent glacier of the summit.\nMcDame Creek Area.\nThis group, comprising the Martin, Bertha, Rowena, Viking, Blue Ribbon\nVollaug Group. Fraction, Alice, Mary, and Sunrise Fraction mineral claims, is owned by\nJohn Vollaug and Hans Erickson, of McDame Creek. The claims are\nstaked from east to west, between about 5,100 and 6,000 feet elevation along the ridged and\ndomed crest of Table Mountain, which flanks the headwaters basin of McDame Creek on the\nsouth. The three westerly claims straddle the west shoulder of the mountain, sloping northerly to McDame Creek and southerly to the Cottonwood River and Pooley Creek, tributaries\nof Dease River. The easterly claims occupy the southerly slope of Table Mountain to Pooley\nCreek. NORTH-WESTERN DISTRICT (No. 1).\nB 25\nn\nr -3'w x'^x-\"r
