G MINING VENTURES REPORTS Q1 2026 PRELIMINARY GOLD PRODUCTION OF 31,846 OZ

G Mining Ventures Corp. has released its preliminary production results for the quarter ended March 31, 2026, from its 100-per-cent-owned Tocantinzinho gold mine (TZ) in Para state, Brazil. Results were in line with the corporation's expectations.

Q1 2026 preliminary highlights

• Gold produced: 31,846 ounces;
• Gold sold: 33,776 oz;
• Average plant throughput: 11,811 tonnes per day;
• Average grade processed: 1.03 grams per tonne Au (gold);
• Gold recovery: 90.3 per cent;
• Strip ratio: 4.40 times.

"TZ delivered consistent operating performance during the first quarter, with results reflecting the planned 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 commentary

TZ delivered stable operating performance during the first quarter, with throughput and recoveries in line with the company's operating plan. Slightly lower metallurgical recoveries were expected with a lower head grade. With the plant now operating at steady state, quarterly production variability is primarily driven by mine sequencing and grade profile.

Gold production reflected the planned processing of lower grade, which was the primary driver of lower output relative to previous quarters. Stockpile rehandling and blending supported consistent plant feed during the quarter.

Mining activities focused on accelerated waste stripping and pit advancement to access higher-grade phase 2 mineralization. As a result, the strip ratio increased to 4.4 times and total material movement reached 5.5 Mt (million tonnes). This elevated stripping is taking place in phase 2 and positions the operation for improved grades and stronger production in the second half of the year, in line with the corporation's mine plan.

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 (second half) 2026 as higher-grade phase 2 mineralization is accessed in accordance with the mine plan.
