LEADING INDEPENDENT PROXY ADVISORY FIRM RECOMMENDS G2 GOLDFIELDS' SHAREHOLDERS VOTE FOR THE ARRANGEMENT WITH G MINING

Institutional Shareholder Services Inc. (ISS), a leading independent proxy advisory firm, has recommended that G2 Goldfields Inc. shareholders vote for the plan of arrangement with G Mining Ventures Corp. to be approved at the upcoming special meeting of shareholders to be held on Tuesday June 16, 2026, at 10 a.m. (Toronto time).

ISS commented: "The merger and connected spinout transaction makes strategic sense as shareholders will henceforth hold shares of two separate publicly listed companies. The board undertook a robust strategic review process, obtained multiple fairness opinions and the independent special committee negotiated an implied value transfer at a level not observed by G2 shareholders since September, 2011."

Board recommendation

The board of directors of the company unanimously recommends that the G2 shareholders vote for the arrangement. The board also unanimously recommends that the G2 shareholders vote for all resolutions pertaining to the spinout of G3 Goldfields Inc.

Your vote is important. Cast your vote well in advance of the proxy voting deadline.

G2 shareholders are encouraged to read the management information circular of the company dated May 12, 2026, and vote your G2 shares as soon as possible, in accordance with the instructions accompanying the form of proxy or voting instruction form mailed to G2 shareholders together with the circular.

The proxy voting deadline is 10 a.m. (Toronto time) on Friday, June 12, 2026.

The company also wishes to provide the following additional disclosure to supplement the disclosure in the circular.
