G Mining Ventures Releases 2025 Production and Cost Guidance

All amounts are in USD unless stated otherwise.

BROSSARD, QC, Jan. 21, 2025 /PRNewswire/ - G Mining Ventures Corp. ("GMIN" or the "Corporation") (TSX: GMIN) (OTCQX: GMINF) announces its 2025 operational and cost guidance for Tocantinzinho Gold Mine ("TZ"), along with planned capital expenditures to progress the Oko West Gold Project ("Oko West") in Guyana and the Gurupi exploration Project ("Gurupi") in Brazil.

Highlights
Production, unit cost and capital expenditure guidance for the full year 2025 are outlined in the table below.

Figure 1: Full Year 2025 Operational and Cost Guidance

"We expect to build on GMIN's 2024 operational success in the year ahead, as TZ ramps up throughput, reaching nameplate capacity early in the year, generating meaningful free cash flow to advance development activities at Oko West," commented Louis-Pierre Gignac, President & Chief Executive Officer, "TZ will remain our focus in 2025 but will be complemented by Oko West development initiatives, including permitting and early works activities. We plan to increase our investment in greenfield and brownfield exploration across our portfolio to uncover low-cost, high-value ounces."

Tocantinzinho Gold Mine

The Corporation is focused on ramping up production and controlling operating costs at TZ. Annual gold production at TZ is forecasted to range between 175,000 and 200,000 ounces. The mill is expected to operate at its nameplate capacity of 12,890 tonnes per day, processing a blend of fresh rock and softer ores, as successfully demonstrated in 2024. Gold output is anticipated to be higher in the second half of the year (56% of the total) as higher-grade mineralization becomes accessible according to the mine plan. The grade segregation and low-grade stockpiling strategy will remain in place in 2025 to manage excess ore mined. Furthermore, in Q1 2025, we aim to complete the installation of an advanced process control system to enhance the efficiency of the grinding and flotation processes at the plant.

Cash Costs and All-in-Sustaining-Costs ("AISC") are expected in the ranges of $590 and $655 per ounce sold and $995 and $1,125 per ounce sold, respectively. The midpoint of cost guidance assumes an average Brazilian Real ("BRL") to US dollar exchange rate of 5.25 for the full year. Approximately 75% of costs are denominated in local currency. The AISC incorporates three years of inflation since the publication of the Feasibility Study, includes corporate costs, and reflects timing variations in sustaining capital expenditures. Mining and processing costs primarily align with standard inflationary trends, while general and administrative ("G&A") costs have increased beyond the Feasibility Study estimates due to higher camp and site service expenses, as well as an expanded G&A team headcount.

Total sustaining capital expenditures for 2025 are projected at $60 to $70 million, which includes $23 million for capitalized stripping and $2 million for near-mine exploration. The near-mine exploration, included in sustaining capital (AISC), encompasses approximately 5,600 meters of drilling to test depth extensions of the deposit and further delineate the northwest extension explored in 2024.

Sustaining capital expenditures, excluding capitalized waste stripping, are estimated at $35 to $45 million. This includes $20 million for mining equipment, $10 million for major components of the mobile fleet, $4.5 million for tailings management, and additional minor expenditures related to the process plant and other capital items.

Regional exploration in the Tapajos within the mining concession and surrounding claims is classified as non-sustaining and excluded from AISC. A budget of $9 million is planned for 2025 to test 23 targets within a 5km radius with the primary goal to identify additional deposits.

Oko West Project

This year, the focus is advancing the Oko West Gold Project by progressing permitting activities to secure a full environmental license from the Guyana Environmental Protection Agency. In the meantime, with the interim environmental permit already in hand, the plan is to commence early works, including site preparation, earthworks, and the construction of the barge landing, permanent camp facilities, and other support infrastructure. To align with the project delivery timeline, the procurement of long-lead items including grinding mills, primary crusher, power generators and mobile equipment fleet will also be initiated. A total budgeted expenditure of $200M to $240M has been allocated, part of the project's initial capital cost. This expenditure is funded by cash on hand and free cash flow generated from TZ.

The Feasibility Study, scheduled for publication in Q2 2025, will feature updated mineral resource and mineral reserve estimates. A favorable outcome from the study, combined with the receipt of final permits, is anticipated to support an official construction decision.

To support the objective of expanding the mineral resource inventory to improve future mine plans and extend the mine's operational life, the Oko West exploration program has been allocated a budget of $8 million. The program focuses on increasing resources within the pit footprint, exploring underground mineralization in Blocks 5 and 6, evaluating additional mineralized saprolite material, and identifying new deposits across the land package.

Gurupi Project

The primary objective at the Gurupi Project is to restart exploration activities this year to expand mineral resources. The plan is also to strengthen relationships with government agencies and regional stakeholders. Exploration efforts will focus on data compilation and interpretation, machine learning-based core relogging, conducting a high-resolution survey across 720 km² of highly prospective terrain, and completing soil sampling on targeted areas. These activities aim to prioritize exploration targets and streamline GMIN's future efforts. Additionally, in Q1 2025, the Corporation plans to release a NI 43-101 compliant mineral resource estimate for the Contact, Blanket, and Chega Tudo deposits. A budget of $2 to 4 million has been allocated for the project.

The guidance ranges reflect the Corporation's operating plans, which include known risks and uncertainties. Unit costs are calculated based on planned production volumes, and variances from estimated production ranges may impact unit costs.

2025 Catalysts

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

• Commencement of early works at Oko West (Q1-2025)
• Oko West FS publication (Q2-2025)
• Oko West financing (Q2-2025)
• Formal construction decision on Oko West (H2-2025)
• Continuation of detailed engineering at Oko West (2025)
• Greenfield and brownfield exploration (2025)
