CORE NICKEL ANNOUNCES BOARD CHANGES

Effective immediately, Paul Reid and Marc Pais have been appointed to the board of directors for Core Nickel Corp., and in turn, Shane Shircliff and Karen Lloyd have each resigned from the board of Core Nickel, effective immediately.

Mr. Reid is the co-founder and past executive chairman of Arizona Metals Corp. He previously co-founded and served as executive chairman of Telegraph Gold Inc. (listed as Castle Mountain Mining Company Ltd.). Mr. Reid worked for 15 years in investment banking and has extensive experience in raising capital, going-public transactions and corporate advisory services.

Mr. Pais is the co-founder and former chief executive officer of Arizona Metals. He previously co-founded and served as CEO of Telegraph Gold Inc. (listed as Castle Mountain Mining Company). Mr. Pais worked for seven years as a mining research analyst, with a focus on exploration and development companies. Mr. Pais holds a BSc in geological engineering (mineral exploration) from Queen's University (Kingston, Ont.).

Mr. Reid, incoming director, commented: "Marc and I recently both became large shareholders of Core and now own 17 per cent and 10 per cent of the company, respectively. Our investment was based on Core's highly prospective exploration projects and strong geological team. The company's two primary assets are in the prolific Thompson nickel belt, with the Mel project located only 25 kilometres from Vale's Thompson mill and the Halfway Lake project located 15 kilometres from the Bucko mill. Based on Core's recent efforts in compiling and digitizing historic drill and geophysical data at both projects, we see the potential for a major new nickel discovery on Core's claims. The company is well funded to start testing a number of exciting drill targets in early 2025."

Misty Urbatsch, the company's CEO and president, stated: "Mr. Shircliff and Ms. Lloyd were instrumental in spinning Core Nickel out of Canalaska Uranium Ltd. and setting the company up for success. Their dedication and vision played a crucial role in getting the company moving forward and we are deeply grateful for their contributions during their time on the board. It is with great pleasure that we welcome Paul Reid and Marc Pais to the board of directors. Having served as key strategic advisers, they both bring a wealth of knowledge and a proven track record of success. Their support and belief in our vision will be invaluable as we continue to drive progress on our tier one assets in the Thompson nickel belt, Manitoba. Welcome Paul and Marc."

About Core Nickel Corp.

Core Nickel is a junior nickel exploration company that controls 100 per cent of five properties in the prolific nickel district, the Thompson nickel belt (TNB) in northern Manitoba, Canada. The five properties consist of approximately 27,000 hectares of land that is proximal to existing infrastructure, such as 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 16 to 20 kilometres 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 National Instrument 43-101 resource estimate with an indicated resource of 4.3 million tonnes at 0.875 per cent nickel, equating to 82.5 million pounds contained nickel, and a historical inferred resource estimate of one million tonnes at 0.839 per cent 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 central 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.
