British Columbia Mine Reclamation Symposium

Preparing a high elevation tailings impoundment for final closure Witt, Peter; Hamaguchi, Bob A.


Highland Valley Copper (HVC), located in south-central British Columbia, 75 kilometres southwest of Kamloops, operates one of the world’s largest copper and molybdenum mines. This paper discusses the Highmont Tailings impoundment concerning its various steps toward final closure. After Highmont Mining ceased operations in 1984, it joined the partnership with HVC in 1988 and moved its concentrator to Lornex. Since then the Highmont tailings have been under care and maintenance and have slowly proceeded towards final closure. As we are now approaching the final phases, this paper explains the various steps taken to bring the Highmont tailings impoundment toward final closure.
