G Mining Ventures Reports Q2 2026 Preliminary Production Results

G Mining Ventures Corp. ("GMIN" or the "Corporation") (TSX: GMIN,OTC:GMINF, OTCQX: GMINF) is pleased to report preliminary production results for the quarter ended June 30, 2026 from its 100%-owned Tocantinzinho Gold Mine ("TZ") in Pará State, Brazil.

TZ produced 36,845 ounces of gold ("Au") in the second quarter of 2026, a 16% 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 tpd
• Average grade processed: 1.23 g/t Au
• Gold recovery: 91.9%
• Strip ratio: 2.78x

"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."

¹ Q2 2026 operating results are preliminary and subject to final reconciliation. Comparative Q2 2025 operating data are derived from the Corporation's previously reported results.

Operational Review
The TZ mine achieved record quarterly mining of 6.3 Mt in Q2 2026, a 15% 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 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%. 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% of annual output forecast for H2 2026 as higher-grade Phase 2 mineralization is accessed in accordance with the mine plan.
