About Core Nickel

Core Nickel Corp. is a junior nickel exploration company that controls 100% of five properties in the prolific nickel district, the Thompson Nickel Belt (TNB) in Northern Manitoba, Canada. The five properties consist of 150,000 hectares of land that is proximal to existing infrastructure, such as highways and operating mills.

Core Nickel has a large contiguous land package in the northern part of the TNB, situated approximately 16-20 km from the City of Thompson. Core Nickel's northern TNB projects consist of three properties: Mel, Hunter, and Odei River. The Mel property encompasses the Mel deposit, which is characterized by a historical NI-43-101 resource estimate with an indicated resource of 4.3 million tonnes at 0.875% nickel, equating to 82.5 million lbs contained nickel, and a historical inferred resource estimate of 1.0 million tonnes at 0.839% nickel, equating to 18.7 million pounds of contained nickel. The target stratigraphy (Pipe Formation) that hosts the Mel deposit, and other deposits in the Thompson Nickel Belt, extend onto the Hunter and Odei River properties and drill hole intersections into the target stratigraphy on the Hunter project have successfully intersected elevated nickel.

The Company also holds two properties in the southern TNB near Wabowden: Halfway Lake and Resting Lake. Both properties host the target Pipe Formation associated with known elevated nickel mineralization and are proximal to existing nickel deposits, mills, and other infrastructure.
