• Tocantinzinho Gold Mine completed on time and on budget, ramping up to nameplate capacity
• 2024 gold production of 63,566 ounces
• Acquired and is fast-tracking the development of the Oko West Gold Project, a globally significant gold discovery with excellent potential to support a large, long-life mine complex
• Acquired the CentroGold Project, an advanced exploration asset in Brazil with a significant existing JORC-compliant resource base
• 94% appreciation in share price during calendar 2024, outperforming the gold price (+26%) and GDXJ (+13%)

BROSSARD, QC, Jan. 8, 2025 /PRNewswire/ - ("GMIN" or the "Corporation") (TSX: GMIN) (OTCQX: GMINF) celebrates a number of key milestones achieved at GMIN's 100% owned Tocantinzinho Gold Mine ("TZ" or the "Mine") in the State of Pará, Brazil, and the Oko West Gold Project ("Oko West" or the "Project") in Guyana. Among the key development and corporate activities accomplished in 2024, GMIN is particularly pleased to report gold ("Au") production of 40,147 ounces ("oz") during the fourth quarter, and full-year gold production since first pour of 63,566 oz. Gold sold during the quarter was 39,938 oz resulting in full-year gold sales of 57,082 oz. The difference between gold sold versus produced was due to the timing of pours at year end and gold in circuit. All figures are as of December 31, 2024, unless stated otherwise.

Table 1. Preliminary Fourth Quarter and Full-Year 2024 Operational Results

Operational results are preliminary in nature and subject to final reconciliation. Financial and operational results for the fourth quarter and year-end 2024 will be released at the end of March, followed by a conference call hosted by senior management.

"Our 2024 milestones mark important steps in GMIN's evolution from developer to producer, and reflect our strategic execution, backed by a best-in-class management team, strong partnerships, and a high-quality portfolio of long-life, low-cost assets that offer multiple value-creation catalysts," commented Louis-Pierre Gignac, President & Chief Executive Officer. "I would like to extend my appreciation to the GMIN team, our supportive shareholders, our partners and communities for all your invaluable contributions and for making 2024 a remarkable year in which we achieved numerous milestones. I am excited about the opportunities ahead as we enter 2025: we remain committed to creating the next leading intermediate gold producer, further ramping up production at TZ, advancing Oko West's feasibility study and making a construction decision on the Project, and advancing exploration at our newly acquired CentroGold project in Brazil."

2024 Highlights:

Tocantinzinho Gold Mine

During the fourth quarter of 2024, the plant achieved several days above 100% of nameplate capacity and GMIN continues to work on increasing plant availability. All aspects of the process plant including crushing, gravity, flotation and leaching circuits are performing well with higher recoveries of 89.2% achieved in Q4‑2024 in line with estimates in the Feasibility Study dated February 09, 2022.

In Q1-2025, the Corporation plans to ramp up production at TZ toward nameplate capacity and confirm exploration plans for greenfield and brownfield targets near the Mine. Potential exploration targets include a 15 km untested parallel trend southwest of the main trend, and underexplored portions of the main 35 km mineralized trend which contains the TZ deposit.

Oko West Gold Project

In 2024, GMIN continued to execute its "Buy. Build. Operate." strategy and remains focused on identifying and developing quality advanced-stage precious metals projects in Tier 1 jurisdictions that demonstrate a path to near-term production.

In 2024, GMIN announced and completed the business combination with Reunion Gold to acquire the high-quality Oko West Gold Project located in Guyana. Shortly after announcing the close of this transaction, GMIN reported PEA results for Oko West, demonstrating after-tax net present value at 5% of US$1.4 billion, internal rate of return of 21% and a payback period of 3.8 years at $1,950/oz base case gold price (long-term consensus). The average annual gold production is estimated to be 353,000 ounces at an AISC of $986/oz over a 12.7-year mine life. The initial capital cost is estimated to be $936 million, with sustaining capital costs of $537 million over the life of mine (see news release dated September 9, 2024). During 2024, a definition drilling program was completed at Oko West in support of the upcoming Feasibility Study ("FS"). Additionally, a new regional exploration drilling program began at Oko West to investigate structures identified through geophysics and geochemical soil anomalies.

Environmental Impact Assessment and Environmental Impact Statement submissions (jointly, "ESIA") were made to the Environmental Protection Agency of Guyana in November 2024. The submission marks a significant step forward in advancing Oko West, emphasizing GMIN's on-going commitment to sustainable and environmentally responsible mining practices. A notice of submission was published in local newspapers in Guyana, with the submission available to the public locally via the ESIA reports in the National Library, University Library, the RDC Region 7 office in Guyana. In addition, the complete ESIA submission has been posted on GMIN's website (Oko West project page).

CentroGold Project

Portfolio growth was a significant theme for GMIN in 2024. GMIN entered into a purchase and sale agreement to acquire tenements in the Gurupi Gold Belt from wholly owned subsidiaries of BHP, and is pleased to announce that this transaction is closed ahead of schedule at the end of 2024. In 2025, GMIN plans to publish a National Instrument 43-101 ("NI 43-101") compliant and updated resource on the project and continue advanced exploration activities.

Corporate Update

In Q4-2024, GMIN welcomed two new Directors to its Board of Directors, bringing the total to 11 members. Mr. Naguib Sawiris and Mr. Vincent Benoit were appointed on October 11 and December 20, respectively. Both highly esteemed individuals bringing significant experience and expertise in corporate finance, business development and M&A in the mining, telecom, real estate and energy sectors. GMIN looks forward to benefiting from their guidance and La Mancha group's continued support.

2025 Catalysts

Over 2025, the Corporation will be focused on the following activities:

• Commencement of early works at Oko West (Q1-2025)
• Full-year production and cost guidance at TZ (Q1-2025)
• Oko West FS publication (Q2-2025)
