PRESS RELEASE TSXV: ALT

Alturas Minerals Proposes Share Consolidation and Debt

Settlement

Toronto, Canada, March 10, 2026 – Alturas Minerals Corp. (the “Company”) (TSX-V) is pleased to announce

that the Company will be seeking shareholder approval for a consolidation of the Company's outstanding

common shares (the "Shares") on the basis of up to a maximum of ten (10) pre-consolidation Shares for

one (1) post-consolidation share (the "Consolidation") at the discretion of the Board of Directors. The

Consolidation will be put to a shareholder vote at the Company's forthcoming Annual General and Special

Meeting ("AGSM") scheduled for April 9, 2026, voting materials for which will be available shortly.

Management is seeking approval for the consolidation in its efforts to attract new opportunities.

Prior to giving effect to the proposed Consolidation, which will also affect all outstanding options and

warrants of the Company, the Company currently has 145,632,143 Shares issued and outstanding.

Assuming a Consolidation on the basis of ten (10) pre-Consolidation Shares for one (1) post Consolidation

Share, the Company will have approximately 14,563,214 post-Consolidation Shares issued and

outstanding. No fractional Common Shares will be issued upon the Consolidation. In the event a holder of

Common Shares would otherwise be entitled to receive a fractional Common Share in connection with the

Consolidation such fractional Common Share that is less than ½ of one (1) post-Consolidation Share will

be cancelled and each fractional Common Share that is at least ½ of one (1) post-Consolidation will be

rounded up to one (1) whole post-Consolidation Share. No cash consideration will be paid in respect of

fractional shares. Shareholders' proportional ownership in the Company will remain unchanged following

the Consolidation. The Consolidation is subject to the receipt of all necessary regulatory approvals,

including the approval of the TSX Venture Exchange, and approval by at least two thirds of the votes cast

by the holders of Shares present in person or by represented proxy at the AGSM. It is anticipated that the

Consolidation will take effect some weeks following the April 9, 2026, AGSM. A letter of transmittal will

be mailed to registered shareholders providing instructions with respect to surrendering share certificates

representing pre-Consolidation Shares in exchange for post-Consolidation Shares issued as a result of the

proposed Consolidation. All registered shareholders who submit a duly completed letter of transmittal along

with their respective share certificate(s) representing the pre-Consolidation Shares to the Company's

transfer agent, Computershare Trust Company of Canada, will receive a certificate representing the post-

Consolidation Shares. Until surrendered, each certificate representing pre-Consolidation Shares will be

deemed to represent the number of post-Consolidation Shares the holder would be entitled to receive as a

result of the Consolidation. Shareholders who hold their Shares in brokerage accounts or in book-entry

form are not required to take any action. Outstanding securities convertible or exercisable into Common

Shares will also be adjusted by the Consolidation ratio, and the exercise price of such securities will be

adjusted accordingly.

upon exemptions from the valuation and minority shareholder approval requirements of MI 61-101
