Thor Lake Deposit

Resource estimates: 65 Mt @ 0.3% Ta, 0.4% Nb, 1.7% REE, 3.5% ZrProven-- 0.507 Mt @ 0.17% Y oxide, 1.11% Be oxide0.51 Mt @ 0.45% REO (1987)Thor Lake is a deposit of rare metals located in the Blachford Lake intrusive complex. It is situated 5 km north of the Hearne Channel of Great Slave Lake, Northwest Territories, Canada, approximately 100 kilometers east-southeast of the capital city of Yellowknife. Geologically located on the Canadian Shield it is mostly composed of peralkaline syenite (granitic rock with low quartz content). The deposit is divided in several sub-structures. In a small zone at the northern edge of the syenite, the T-Zone, minerals like bastnäsite, phenakite and xenotime can be found.

Within the Mackenzie mining district, Thor Lake may contain some of the largest deposits of light and heavy rare earth element (REE) ores. The major elements of these ores are europium, terbium, dysprosium, neodymium, gallium, niobium, thorium, zirconium and beryllium.
