British Columbia Mine Reclamation Symposium

Reclamation of mine openings at the historic Highland Mine and Kootenay-Florence Mines, Ainsworth, British Columbia Mchaina, David Mhina; Weirmeir, Michael


This paper discusses mine closure aspects of an abandoned mine workings located in southeast British Columbia. The Highland Mine and adjacent mines were discovered in the 1890's and produced at various intervals until the late 1950's. During the summer of 1997, one of the old Highland Mine portals collapsed and released an unknown quantity of iron-rich water into Cedar Creek. This event led to a review of all the surface openings of the Company's Ainsworth lands in terms of meeting the BC Health, Safety and Reclamation Code requirements. The closure aspects considered included preliminary assessment, site investigations, decommissioning and reclamation work planning, design implementation, cost estimates, alternative evaluation, contractor selection and implementation. The paper will also address environmental, stakeholder consultation aspects and follow-up.
