G MINING VENTURES REPORTS FOURTH QUARTER 2025 OPERATIONAL RESULTS

G Mining Ventures Corp. has provided its preliminary production results for the fourth quarter and full year ended Dec. 31, 2025, for the Tocantinzinho gold mine (TZ), located in the state of Para, Brazil.

During the fourth quarter, TZ produced 47,346 ounces of gold, with the mill processing 1,077,000 tonnes of ore at an average grade of 1.49 grams per tonne gold and achieving recoveries of 91.8 per cent.

For the full year, TZ produced 171,871 ounces of gold, from the processing of 4,086,000 tonnes of ore at an average grade of 1.44 grams per tonne gold and recoveries averaging 90.6 per cent.

"Tocantinzinho delivered a strong fourth quarter, successfully closing its first full year of commercial production," commented Louis-Pierre Gignac, president and chief executive officer. "Continued optimization initiatives are driving improvements in mine and plant productivity. These strong operational results were achieved alongside a solid safety performance, with only two lost-time incidents, resulting in a lost-time injury frequency rate of 0.15."

Fourth quarter and full-year 2025 production results highlights:

• The average mining rate increased to 64,700 tonnes per day, representing an 18-per-cent rise compared with Q3 2025 following the commissioning of additional mining equipment;

• Gold sales amounted to 47,457 ounces for the fourth quarter and 172,093 ounces for the full year.
