The Trans-Canada Property is comprised of 28,550 hectares of mineral claims (including patents, leases and staked claims) located some 200 kilometres northeast of Thunder Bay within the Municipality of Greenstone. Major projects within the property include Hardrock, Brookbank, Key Lake, Northern Empire,Leitch-Sand River and Nortoba-Tyson.
The first discovery of gold in the property area was of a gold-bearing boulder found south of the Main Narrows of Kenogamisis Lake between 1916 and 1918. This was followed by a number of discoveries made across the property resulting insignificant gold mine production between 1930 and 1970.
As of February 5, 2015 the Trans-Canada Property contains only mineral resources. Mineral resource estimates have been completed on behalf of Premier Gold at the Hardrock, Brookbank, Key Lake and Kailey deposits.
Between 1970 and 2007, exploration was often limited in scope and duration; however, important discoveries such as Brookbank and Key Lake were made. Beginning in 2007, Premier Gold Mines Ltd. embarked on significant exploration campaigns, primarily in the eastern portion of the belt, that have resulted in important discoveries of mineralization potentially amenable to both open pit and underground mining methods. In excess of 700,000 metres of diamond drilling has been conducted in the ensuing period.
