CORE NICKEL ANNOUNCES ADOPTION OF ADVANCE NOTICE POLICY

The board of directors of Core Nickel Corp. has adopted an advance notice policy, establishing a framework for advance-notice nominations of directors by shareholders of the company. The policy includes, among other things, a provision that requires advance notice be given to the company in circumstances where nominations of persons for election to the board are made by shareholders of the company other than pursuant to: (i) a requisition of a meeting made pursuant to the provisions of the Business Corporations Act (British Columbia) (BCBCA); or (ii) a shareholder proposal made pursuant to the provisions of the BCBCA.

Additionally, the policy sets a deadline by which holders of record of common shares of Core Nickel must submit director nominations to the company prior to any annual or special meeting of shareholders, sets forth the information that a shareholder must include in the notice to the company, and establishes the form in which the shareholder must submit the notice for that notice to be in proper written form.

With respect to the annual general and special meeting of shareholders of the company to be held on Oct. 22, 2024, notice of any proposed nominations must be provided to the company no later than Sept. 22, 2024.

For all subsequent meetings of shareholders of the company:

1. In the case of an annual meeting of shareholders, notice of a director nomination must be given to the company not less than 30 days nor more than 65 days prior to the date of the annual meeting of shareholders; provided, however, that in the event that the annual meeting of shareholders is called for a date that is less than 40 days after the date on which the first public announcement of the date of the annual meeting was made, notice may be made not later than the close of business on the 10th day following such public announcement.
2. In the case of a special meeting of shareholders (which is not also an annual meeting) called for the purpose of electing directors (whether or not called for other purposes), notice of a director nomination must be given to the company no later than the close of business on the 15th day following the day on which the first public announcement of the date of the special meeting was made.

The policy is effective immediately. At the meeting, the company is seeking shareholder approval and ratification of the policy. In the event that shareholders determine not to ratify the policy by ordinary resolution, the policy shall terminate and be void and of no further force and effect following the termination of the meeting.

The full text of the policy is available under the company's profile on SEDAR+ and a copy and a summary of the policy will be included in the management information circular for the meeting, which will be sent to shareholders in due course.

About Core Nickel Corp.

Core Nickel is a junior nickel exploration company that controls 100 per cent of five properties in the Thompson nickel belt (TNB), a prolific nickel district, in Northern Manitoba, Canada. The five properties consist of approximately 27,000 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 kilometres 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 extends 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.
