BROSSARD, QC , July 8, 2025 /CNW/ - G Mining Ventures Corp. ("GMIN" or the "Corporation") (TSX: GMIN) (OTCQX: GMINF) is pleased to announce that its Tocantinzinho Gold Mine ("TZ") in the State of Pará, Brazil reached a major operational milestone, with the processing plant operating at an average of 12,890 tonnes per day ("tpd") over 30 consecutive days. The Corporation also reports gold ("Au") production for the second quarter of 2025 of 42,587 ounces ("oz").

Second Quarter 2025 Production Highlights

• No lost time or recordable incidents in Q2 2025
• Q2-2025 gold production of 42,587 ounces, a 20% increase over Q1 2025
• Gold recovery improved to 90.3% (from 87.7% in Q1 2025)
• Average mining rate of ~47,900 tpd, an 18% increase from Q1 2025
• Average plant throughput of 11,100 tpd or 86% of nameplate
  • April: 8,600 tpd (67% of nameplate)
  • May and June: 12,300 tpd (96% of nameplate)

"The team at TZ has delivered an impressive Q2 following the SAG mill liner challenges earlier this year, leading to a successful ramp up to nameplate throughput," said Louis-Pierre Gignac, President & Chief Executive Officer. "Since implementing the new liner, the mill has operated with excellent stability, higher throughput, and robust gold recoveries. These results demonstrate our technical capabilities and disciplined execution, keeping us firmly on track to achieve our 2025 production targets."

Tocantinzinho Key Production Highlights:

Tocantinzinho Processing Update

During the ramp-up phase of the TZ mine, GMIN identified premature wear of the poly-met liners in the Semi-Autogenous Grinding ("SAG") mill, which resulted in frequent unscheduled downtime for liner replacements. While the mill performed as designed when running, these repeated shutdowns lowered the plant availability, resulting in less tonnage processed. To resolve the issue, the Corporation completed a permanent replacement of the rubber liners with a steel system in April, effectively eliminating the need for unplanned stoppages with normal wear expected going forward.

Since the installation of the steel liners in April, the mill has performed to expectations, achieving an average throughput of 96% of nameplate for the months of May and June, with an exceptional 103% of nameplate for the month of May. This performance demonstrates the robustness of the permanent solution and highlights the stability of the TZ processing circuit.

The expert control systems installed on the SAG mill and flotation circuit have contributed to increased plant throughput, enhanced stability and improved gold recoveries.

Tocantinzinho Mining Update

The mine delivered strong operational performance in Q2, achieving an average mining rate of 47,900 tpd — an 18% increase over Q1, which had been adversely impacted by above-average rainfall relative to historical data. During the quarter, additional mine fleet equipment was delivered to Brazil, with assembly and commissioning scheduled for Q3. This deployment is expected to further elevate mining production in the second half of the year. The newly acquired equipment will be classified as sustaining capital and will be reflected in the Q2 AISC cost metrics accordingly.

Strong Operational Performance Underway

2025 production guidance for the TZ mine is forecast to be between 175,000 to 200,000 gold ounces, with a 44% of the production targeted for H1 and 56% in H2.

Second-quarter gold production totaled 42,587 ounces, representing 23% of the midpoint of annual guidance, slightly above the planned 22%.

First-half 2025 gold production totaled 78,165 ounces, representing 42% of the midpoint of annual guidance, slightly below the planned 44%.

2025 Outlook Reaffirmed

Following the successful resolution of the SAG mill issue, GMIN reiterates its previously issued 2025 production guidance for the TZ mine of 175,000 to 200,000 oz. Commentary on cost guidance will be provided with the upcoming Q2 results.

2025 Catalysts

Over 2025, the Corporation will focus on the following activities:

• Final environmental permit for Oko West (early Q3 2025)
• Oko West financing and construction decision (H2-2025)
• Greenfield and brownfield exploration (TZ, Oko West and Gurupi) (2025)
