Fonds 264 - Thompson-Lundmark Gold Mines Limited fonds

Thompson-Lundmark Gold Mines Limited was incorporated on August 31, 1938, following the staking of 46 claims the preceding month by Fred W. Thompson and Roy Lundmark at Thompson Lake, 48 kilometres northeast of Yellowknife. Work at the gold mine site began in 1939 and focused on the Kim and Fraser veins. Thompson-Lundmark Gold Mines Limited was hindered by a lack of funds in 1940, until Cominco Limited agreed to provide the necessary financial support to bring the mine into production. Through this arrangement, Cominco assumed management of the mine and developed a 96-ton/day mill that was underway by the summer of that year.

The mine was greatly affected by labour and supply shortages due to World War II, and in August 1943, Cominco recommended that the mine be shut down yet minimally maintained. Thompson-Lundmark Gold Mines Limited was eventually able to repay the Cominco loans, and by July 1946, operating control of the gold property had reverted back to its original owners. Work continued on the Island, Trail, Fraser, and Kim veins in the fall of 1946. Development of the property continued, particularly underground, and in late 1947 changes were implemented to make the operation of the mine more efficient. Despite these improvements, the Thompson-Lundmark Gold Mines Limited treasury was slowly being depleted due to high operational costs in manpower, mobilization, and power allocations, as well as a price of gold that did not rise. The mine closed in 1949 and was put on care and maintenance. The majority of the equipment was removed and sold; only the milling and boiler plant remained at the site.

Thompson-Lundmark Gold Mines Limited was amalgamated into Consolidated Thompson-Lundmark Gold Mines Limited on December 18, 1985, which then was itself amalgamated into Cliffs Quebec Iron Mining Limited / Cliffs Québec Mine de Fer Limitée on July 1, 1989.

A forest fire destroyed the Thompson-Lundmark Gold Mine site in the summer of 1998.
