G MINING VENTURES REPORTS Q2 2026 PRELIMINARY PRODUCTION RESULTS

G Mining Ventures Corp. has released preliminary production results for the quarter ended June 30, 2026, from its 100-per -cent-owned Tocantinzinho gold mine (TZ) in Para state, Brazil.

TZ produced 36,845 ounces of gold (Au) in the second quarter of 2026, a 16-per-cent increase from Q1 2026. On a year-to-date basis, the corporation has produced and sold 68,691 ounces of gold and 71,215 oz Au, respectively. The corporation remains on track to achieve full-year production guidance of 160,000 to 190,000 ounces of gold.

Preliminary second quarter 2026 operational results highlights:

• Gold produced: 36,845 oz;
• Gold sold: 37,439 oz;
• Average plant throughput: 11,121 tonnes per day;
• Average grade processed: 1.23 grams per tonne Au;
• Gold recovery: 91.9 per cent;
• Strip ratio: 2.78 times.

"Second quarter operational results tracked broadly to plan, with results reflecting the sequencing of lower-grade material as mining activities focused on waste stripping and pit advancement," said Louis-Pierre Gignac, president and chief executive officer. "This work supports access to higher-grade phase 2 mineralization and positions the operation for a meaningful increase in grade and production in the second half of 2026, in line with our guidance."

Operational review

The TZ mine achieved record quarterly mining of 6.3 Mt (million tonnes) in Q2 2026, a 15-per-cent increase over Q1 2026. The planned commissioning of additional haul trucks and a front-end loader in Q3 2026 is expected to further support increased mining rates. 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 during the second half of 2026 allowing for substantially lower costs, consistent with guidance. Stockpile rehandling and blending continued to support stable and consistent plant feed throughout the quarter.

TZ maintained steady plant throughput during the quarter, processing 1,012 kt (thousand tonnes) or ore at an average rate of 11,121 tonnes per day (tpd). The average processed grade was 1.23 g/t Au and the average recovery was 91.9 per cent. In the second quarter of 2026, 36,845 ounces of gold were produced and 37,439 ounces of gold were sold. Differences between gold ounces produced and gold ounces sold are primarily due to shipment and refining timing differences.

On track to deliver 2026 guidance

The corporation maintains its 2026 production guidance of 160,000 to 190,000 ounces of gold. Production is expected to be weighted toward the second half of the year, with approximately 62 per cent of annual output forecast for H2 2026 as higher-grade phase 2 mineralization is accessed in accordance with the mine plan.
