The Arrangement

On April 9, 2026, G2 entered into a definitive agreement with G Mining Ventures Corp. (“GMIN”) and G3 Goldfields Inc. (“G3”) pursuant to which GMIN will acquire all of the common shares of G2 (the “G2 Shares”) and G2 will complete a spin-out transaction with G3 (the “Spin-Out”) pursuant to a plan of arrangement under the Canada Business Corporations Act (the “Arrangement”). At the Meeting, the G2 Shareholders will be asked to consider and, if deemed advisable, pass a special resolution (the “Arrangement Resolution”) approving the Arrangement and resolutions approving matters relating to the Spin-Out.

If the Arrangement becomes effective, G2 Shareholders will be entitled to receive (i) 0.212 (the “Exchange Ratio”) of a common share of GMIN (each whole share, a “GMIN Share”) and (ii) 0.5 of a common share of G3 (each whole share, a “G3 Share”), resulting in approximately 19.9% of the issued and outstanding GMIN Shares and 100% of the issued and outstanding G3 Shares being owned by G2 securityholders upon completion of the Arrangement.

Subject to the receipt of shareholder and court approvals, the Arrangement is anticipated to be completed in early July 2026.

• Immediate and significant premium of 72% based on the 30-day volume-weighted average prices of the GMIN Shares and G2 Shares on the Toronto Stock Exchange as of April 8, 2026 (prior to any incremental value from G3).

• Creation of a Tier-1 Gold District in Guyana through the combination of G2’s Oko-Ghanie Project with GMIN’s adjacent Oko West Project, with self-funded, meaningful long-term exploration upside.
