Average plant throughput: 12,372 tpd
Average grade processed: 1.33 g/t Au
Gold recovery: 92.0%

"Our third quarter operational results were solid and delivered the step-up in production we expected to support a strong second half of the year, with higher grades and improved gold recoveries driving production of 44,960 ounces for the quarter,” commented Louis-Pierre Gignac, President and Chief Executive Officer of GMIN. “TZ continues to perform very well, with mining rates averaging 74,209 tpd during the quarter, a 7% increase over Q2 2026. Throughput rates at the processing plant averaged 12,372 tpd with gold grades of 1.33 grams per tonne and gold recoveries of 92.0%, representing the strongest quarterly results year-to-date.”

“Mining activities remain closely aligned with the mine plan, enabling access to higher-grade Phase 2 mineralization and positioning the operation for a significant increase in grade and production in Q4,” continued Mr. Gignac. “Building on the strong operational performance delivered this quarter and together with the continued advancement of our exploration programs, we expect to deliver a strong finish to 2026 and carry that momentum into 2027."

Forward-looking statements are based on expectations, estimates and projections as of the time of this press release. Forward-looking statements are necessarily based upon several estimates and assumptions that, while considered reasonable by the Corporation as of the time of such statements, are inherently subject to significant business, economic and competitive uncertainties and contingencies. These estimates and assumptions may prove to be incorrect. Such assumptions include, without limitation, those relating to GMIN continuing to improve operational results and generate free cash flow as well as profitability, those relating to the price of gold and currency exchange rates, those outlined in feasibility and other technical studies relating to GMIN’s mining assets, and those underlying the items listed on the above section entitled “About G Mining Ventures Corp.”.

Many of these uncertainties and contingencies can directly or indirectly affect, and could cause, actual results to differ materially from those expressed or implied in any forward-looking statements. There can be no assurance that, notably but without limitation, (i) TZ will continue operating and delivering production, recoveries and costs that will remain in line with expectations; (ii) GMIN will achieve the midpoint of full-year production guidance; (iii) a meaningful increase in grade and production will take place in Q4-2026; (iv) mining activities will remain closely aligned with the mine plan; (v) the higher-grade Phase 2 mineralization will be accessed in Q4-2026, or at all; (vi) Oko West will be brought into commercial production in 2028, or at all; or (vii) GMIN will use TZ and Oko West to grow into the next mid-tier precious metals producer, as future events could differ materially from what is currently anticipated by the Corporation. In addition, there can be no assurance that Brazil and/or Guyana will remain mining friendly and prospective jurisdictions.

By their very nature, forward-looking statements involve inherent risks and uncertainties, both general and specific, and risks exist that estimates, forecasts, projections and other forward-looking statements will not be achieved or that assumptions do not reflect future experience.
