NEW YORK,June 2,2023 -- Pelham Investment Partners LP ("Pelham","we","our" and similar pronouns),a New York-based investment fund and the single largest shareholder of Nickel 28 Capital Corp. (formerly Conic Metals Corp.) (TSXV: NKL) (FSE: 3JC0) ("Nickel 28" or the "Company"),is pleased to announce the positive momentum building behind its campaign to change the board of directors of Nickel28 (the "Board"),both in the form of public shareholder support and a recommendation for change from Institutional Shareholder Services ("ISS"),a leading independent proxy advisory firm.

Growing Shareholder Momentum in Support of Change at Nickel 28

Pelham is pleased to report that many shareholders – both larger institutions and retail holders – have already voted for all of Pelham's director nominees (the "Pelham Nominees"),using the YELLOW Proxy,at the upcoming annual general and special meeting of shareholders of the Company,currently scheduled to be held on June 12,2023 (including any adjournment(s) or postponement(s),the "Meeting").

One of these shareholders is Samara Capital Inc. ("Samara Capital"),a registered portfolio manager that holds voting control over approximately 7.4% of the outstanding shares of Nickel 28 as of the record date. Yesterday,Samara Capital publicly announced that it has elected to support the Pelham Nominees (who can be voted "FOR" using only the YELLOW Proxy). Many other fellow shareholders are doing the same. We encourage all shareholders to join our campaign for change and a better future for your investment in Nickel 28.

ISS Recognizes Need for Change to the Board of Nickel 28

ISS recently issued a report for its subscribers,where it recommended that Nickel 28 shareholders vote for change using only the YELLOW proxy,stating in its conclusion that:1

"…several credible governance and compensation issues have been raised and the responses taken by the company suggest a reactive posture due to revelations made by the dissident. Taken in totality,the historical board interlock and compensation issues highlighted are concerning enough to suggest there could be some benefit from additional independent oversight of management on the board."

The Company chose to reveal only part of the story when it came to ISS' report,grossly misrepresenting ISS' conclusions to shareholders in a self-serving news release issued yesterday. While Pelham feels that ISS' recommendation ultimately underestimates the degree of Board change needed to secure the best outcome for shareholders,Pelham is nonetheless pleased that ISS noted the following in its report:

On Governance Concerns Regarding Incumbent Directors

"Under ISS benchmark policy,shareholders would normally be recommended to withhold votes from management nominees Cochrane and Williams due to Cochrane's service as an executive director on the Audit Committee in the first case,and Williams being considered overboarded in the second case."

- and -

"Per an amended filing made on May 29,2023,the company has indicated that Williams is no longer identified as independent by the company; responding to a significant point of contention by the dissident but not clearing up (beyond admission of oversight) why shareholders were forced to accept this as practice for several years."

On the last-minute appointment of Lance C. Frericks to the Board:

"The board has taken some reactive steps to try and improve independence,however,this has resulted in an independent management nominee with weaker qualifications being added to the board in lieu of one of the more qualified dissident nominees."

- and -

"Although the board has recently added an independent director in Lance C. Frericks,he appears to provide the least relevant skills and experience to the board of the entire management slate and was not found through a formal search program."

On the need for more independent Board oversight of compensation:

"…the number of compensation issues and overall quantum of pay discussed in previous sections suggests that board independence at NKL could have contributed to some of the company's issues."

- and -

"…additional independent board oversight,specifically on the compensation committee,could serve to enhance and rationalize the company's compensation practices."

Further details concerning the Pelham Nominees,as well as Pelham's concerns regarding the Board's long–standing governance failures,lack of independent oversight and excessive executive compensation,are available in Pelham's information circular mailed to shareholders and which is available at savenickel28.com (as well as on the Company's SEDAR profile at www.sedar.com).

Vote ONLY the YELLOW Proxy

!

Pelham reminds shareholders that it has designed the YELLOW Proxy as a "universal" proxy,meaning that all of the Pelham Nominees,as well as management's nominees,are included as voting options. Pelham determined to provide shareholders with a universal proxy as the practice of utilizing a universal proxy in a contested meeting is becoming increasingly recognized as a governance best practice.

Regardless of the outcome of the litigation spurred by the Board's self-serving decision to reject Pelham's advance notice of nominations,votes cast using the YELLOW Proxy will count. If the Pelham Nominees are able to stand for election,votes cast for those nominees on Pelham's YELLOW Proxy will count. If Pelham's nominees are not able to stand for election,withhold votes cast against the current directors on Pelham's YELLOW Proxy will count.

Pelham urges shareholders to vote only the YELLOW Proxy,regardless of how shareholders intend to vote,and regardless of the outcome of the pending litigation,and disregard any proxies or voting instruction forms received from management.

Only the Pelham Nominees will hold the Company to a higher standard – one that the Company is certainly capable of meeting and shareholders deserve – but not under current management.

Time is of the essence.In order to ensure your vote is counted at the Meeting,please ensure that your YELLOW proxy or voting instruction form is received prior to the proxy voting deadline of 9:00 p.m. (Eastern time) on June 7,2023.

Even if you have already voted using a blue management proxy or voting instruction form,you have every right to change your vote by using the YELLOW form of proxy or voting instruction from to support the election of the Pelham Nominees,or the withholding of votes against management's nominees,or any combination thereof. A later-dated YELLOW Proxy or voting instruction form automatically revokes any and all previously submitted forms of proxy or voting instruction forms.
