Nickel 28 Files Supplement to Circular for Upcoming Annual General and Special Meeting of Shareholders

Supplement Highlights Reasons to Vote BLUE Proxy and Provides Additional Information about Nickel 28’s Highly Aligned Board

Pelham Has No Compelling Case for Change and No Real Plan for Your Investment

Nickel 28 Shareholders Vote Your BLUE Proxy Today!

TORONTO–(BUSINESS WIRE)–$NKL #mining–Nickel 28 Capital Corp. (“Nickel 28” or the “Company”) (TSXV: NKL) (FSE: 3JC0) announced that it has filed a supplement (the “Supplement”) dated May 27, 2023 that modifies and supplements its management information circular (the “Circular”) dated May 10, 2023 and related proxy materials in connection with its annual general and special meeting (the “Meeting”) of shareholders scheduled for June 12, 2023 at 10:00 a.m. (Toronto time).

The Supplement provides additional information about the Company’s five highly qualified nominees for the board of directors (the “Board”) on the BLUE proxy. In addition, the Supplement reminds shareholders that the chairman of the Meeting (the “Chairman”), advised by independent counsel, previously determined that Pelham Investment Partners LP’s (“Pelham”) failed to deliver a proper notice (the “Notice”) in compliance with the Company’s advance notice provisions under its articles.

As previously disclosed, the Chairman’s independent legal counsel has commenced a proceeding in the Supreme Court of British Columbia seeking a declaration confirming the decisions made by him in respect of the Notice and the Meeting. Pelham is purporting to solicit votes for its nominees in contravention of the Chairman’s determination that the director nominations contained in the Notice will not be considered for election to the Board at the Meeting.

While the Chairman remains resolute in his commitment to ensuring the Meeting occurs in accordance with the Company’s articles and applicable laws and has notified Pelham that it will not be entitled to nominate directors, the Company is reiterating the reasons why shareholders should vote their shares in favor of the Company’s nominees in the Supplement in the face of Pelham’s challenge to the Chairman’s determination.

The Supplement reiterates:

• The many important reasons to support Nickel 28’s recommended director nominees on the BLUE proxy, who have delivered for shareholders and positioned the Company to become a leading battery metals investment vehicle.

• The reasons to withhold your votes from Pelham’s nominees, (if their nominations are determined to be valid by the Court), including their lack of a plan to run the business and drive value for shareholders, and the nominees’ lack of the necessary skills, experience and expertise.

Vote the BLUE Proxy or BLUE VIF FOR Nickel 28’s five director nominees to continue Nickel 28’s proven strategy for value creation and strong momentum. Nickel 28 encourages you to vote well before the proxy voting deadline on June 8, 2023 at 10:00 a.m. (Toronto time).

The Circular and the Supplement provide important information on the business of the meeting, including Nickel 28’s Board, as well as related matters such as voting procedures and how to attend the Meeting. Shareholders are urged to read the Circular and Supplement carefully and in their entirety. The Circular and Supplement are available on Nickel 28’s website at www.ProtectNKL28.com and under the Company’s profile on SEDAR at www.sedar.com.
