La Mancha Exercises Right to Subscribe for Additional Shares of

G Mining Ventures

BROSSARD, QC, March 9, 2026 – G Mining Ventures Corp. (“GMIN” or the “Corporation ”) (TSX:GMIN,

OTCQX:GMINF) announces that the Corporation’s largest shareholder, La Mancha Investments S.à r.l.

(“La Mancha” ), has elected to exercise its top-up right pursuant to the investor rights agreement

between the Corporation and La Mancha that was initially entered into on July 22, 2022 and

subsequently updated on July 15, 2024 , which allows La Mancha to increase its ownership to up to

19.9%. This transaction represented the final opportunity for La Mancha to exercise its right to increase

its ownership to such level, after which La Mancha retains only customary anti-dilution rights.

Louis-Pierre Gignac, President and Chief Executive Officer , stated: “This additional investment by La

Mancha further demonstrates its long -term support and its strong conviction in our ability to create

shareholder value as we continue our evolution into a leading intermediate gold producer . “

In connection with the exercise of La Mancha’s long-standing top-up right, the Corporation has agreed

to issue 9,311,745 common shares (the “Top-Up Shares”) to La Mancha at a price of CAD45.89 per

Top-Up Share, for aggregate gross proceeds of approximately CAD427 million. There are no fees or

commissions payable on the La Mancha subscription, which is expected to close on or about March

11, 2026, subject to customary closing conditions, including receipt of the Toronto Stock Exchange

approval. Following the issuance of the Top-Up Shares, La Mancha will beneficially own approximately

19.9% of the issued and outstanding common shares of the Corporation.

Vincent Benoit, Managing Partner and Chief Investment Officer of La Mancha, commented: The

investment reflects that La Mancha continues to see significant value creation potential in the

Corporation . G Mining’s strong performance and execution to date have reinforced La Mancha’s original

investment thesis, which remains firmly supported by the Corporation’s growth strategy, portfolio of high-

quality gold assets in Latin America, and highly experienced management team with a proven track

record of building and operating mines. ”

The Oko West Gold Project remains on-budget and on-schedule for first gold pour in the second half

of 2027 and continues to be fully funded by the Corporation’s balance sheet and cash flow. The

Corporation intends to use the proceeds from the issuance of the Top -Up Shares to reduce reliance

on debt pertaining to Oko West Project development, increase exploration efforts, accelerate debt

repayment, and for general corporate purposes.
