Controlled implosion fells gold frame headframe.
Con Mine’s Robertson headframe, the tallest structure in Canada’s Northwest Territories, was levelled by a controlled explosion Saturday afternoon.
At 76 metres tall, the white and black mine shaft with a red top hat was visible from nearly any vantage point in Yellowknife.
The property was staked by Consolidated Mining and Smelting Company of Canada (Cominco) in September 1935 in response to the discovery of visible gold nearby.
The Con Mine entered production in 1938 and ceased operations in 2003. It produced over 160,000 kg of gold from 12,195,585 tons of ore processed. The mine was over 1,800 metres deep.
