The Moose Project
Great Slave Lake, Northwest Territories
TNR recently staked the Moose Lithium-Tantalum-Niobium occurrence located 115 km east-southeast of Yellowknife, near the shore of Great Slave Lake in the Northwest Territories. Access to the property is by barge in summer and across the ice in winter.
The Moose is one of the best-known members of the Hearne Channel -- Buckham Lake Pegmatites. Within 8 km of the Moose are another 4 occurrences of spodumene and columbite-tantalite bearing pegmatites: Best Bet, Moose 1 Dyke, Big Hill #2, and Blatchford Lake.
The Moose underwent minor production between 1947 and 1954:
• 1947: 33 tonnes of ore processed at a mill on site
• 1953 -- 1954: 4409 tonnes averaging 1.65 kg tantalite-columbite per tonne and 119 tonnes of lithium bearing amblygonite produced
The Moose is a zoned pegmatite that occurs as a series of exposures up to 25 m wide over a 425 m exposed strike length
. It consists of two distinct zones: 1) lithium-bearing zones, and 2) tantalum-niobium bearing zones. Historically the pegmatite body was estimated to contain 771,610 tonnes of ore, of which 471,784 tonnes are lithium-bearing, and 299,715 tonnes are tantalum-niobium-bearing zones. One spodumene-bearing zone has been estimated to contain 303,133 tonnes averaging 30% spodumene, which has assayed up to 7.44% Li2O. The tantalum-niobium-bearing ore pile averaged 0.104% Ta2O5, and concentrate from operation in 1947 reported to contained 35.03% Ta2O5 and 41.36% Nb2O5.
Since the Moose property has experienced only a limited amount of drilling, and the deposit is still open at depth and on strike, potential for significant expansion of tonnage exists on the property. In addition to confirming and expanding historic resources TNR aims to further explore the property for other lithium and tantalum enriched pegmatite dykes yet to be discovered.
