History
The Agnew Lake Mine was owned and operated by Kerr Addison Mines Ltd,[2][3] the mine began producing uranium in 1977, utilizing both underground and surface mining techniques.[4] Agnew Lake was the first biohydrometallurgy mining operation. Underground mining was done via sublevel stoping, with oversize rock skipped to surface via a shaft, bioleaching was carried out both underground and on surface stockpiles to produce Triuranium octoxide (U3O8). By the end of 1980 underground mining stopped, and by 1983 the mine closed.[2]
The Agnew Lake mine site was decommissioned, buildings removed, and the shaft capped. Monitoring of the site was carried out by Kerr Addison between 1983 and 1988, with the property being turned over to the Ontario government in the early 1990s.[3]
Geology
The uranium mineralization at Agnew Lake is contained within a pyritic quartz-pebble conglomerate that unconformably overlies granitic rocks.[2] This is similar to the style of mineralization found in the Elliot Lake uranium camp.
