Building Canada’s Next Gold Mining District

TMAC has a 100% interest in the 1,101 square kilometre (approximately 80 km by 20 km) Hope Bay Property located in Nunavut, Canada. The Hope Bay Property is a high-grade gold district with established Measured and Indicated Mineral Resources totaling approximately 5.17 million ounces of gold at an average grade of 7.4 g/t Au and Inferred Mineral Resources totaling approximately 2.13 million ounces of gold at an average grade of 6.1 g/t Au. Proven and Probable Mineral Reserves total approximately 3.54 million ounces of gold at an average grade of 6.5 g/t Au (estimates have an effective date of December 31, 2019. Mineral Resources are inclusive of those resources converted to Mineral Reserves).

In addition to the Hope Bay property, in 2013, TMAC acquired from Newmont a 100% interest in the original Elu claims, a greenstone belt to the east of the Hope Bay claims covering 31,259 hectares. The Elu greenstone belt is similar in age to the Hope Bay belt and has the potential to host both gold and base metal deposits. In June 2016, TMAC staked the extension of the Elu greenstone belt, comprising 37,214 hectares, thereby linking the Elu claims with the Hope Bay claims. The Elu claims now form a land package that comprises an area of 685 square kilometers and is approximately 80 kilometers by 10 kilometers in extent. The majority of the Elu claims are on Inuit-owned lands that are not included in the Inuit-owned surface access rights provided through the Framework Agreement. The Crown owns 100% of the Elu subsurface mineral claims.
