About Core Nickel Corp.

Core Nickel is a junior nickel exploration company that controls 100 per cent of five projects in the Thompson nickel belt (TNB), a prolific nickel district located in Northern Manitoba, Canada. The five projects consist of approximately 27,000 hectares of land that is proximal to existing infrastructure, including highways, railways, major hydroelectric transmission lines and operating mills.

Core Nickel has a large contiguous land package in the northern part of the TNB, situated approximately 15 to 20 kilometres from the city of Thompson. Core Nickel's Mel project encompasses the Mel deposit, which is characterized by a historical mineral resource consisting of an indicated resource of 4,279,000 tonnes grading 0.875 per cent nickel plus an inferred resource of 1.01 million tonnes grading 0.839 per cent nickel, at a cut-off of 0.5 per cent nickel. The target stratigraphy (Pipe formation) that hosts the Mel deposit and other deposits in the Thompson nickel belt extends onto the Hunter and Odei River projects and drill hole intersections into the target stratigraphy on the Hunter project have successfully intersected anomalous nickel.
