Toronto, Ontario — January 8, 2026 — Leads & Copy — Omai Gold Mines Corp. (TSXV: OMG) (OTCQB: OMGGF) has released a summary of its 2025 achievements and outlined upcoming milestones for its 100%-owned Omai Gold Project in Guyana. The company anticipates that these milestones will lead to shareholder returns in 2026.
In 2025, drilling results expanded the mineral resource base, which was announced in August. By the end of the year, an additional ~18,000m had been drilled, with assay results expected shortly. This drilling will inform an updated MRE in Q1, followed by a Preliminary Economic Assessment (PEA) in early Q2 2026. The upcoming PEA is expected to include an expanded mine plan, incorporating both the Wenot open pit deposit and the adjacent Gilt Creek underground deposit.
Last year was marked by project advancements including resource growth, exploration success, permitting progress, and work on the Gilt Creek underground mine plan, tailings plan, metallurgy, and baseline studies. According to the press release, these advancements contributed to Omai Gold’s (OMG.V) >500% share appreciation in 2025. The company also completed two private placements to strengthen its balance sheet, added new institutional shareholders, and increased analyst coverage.
Omai Gold reported the stage is set for project advancements, market recognition, and value creation in 2026.
2025 Highlights:
The company completed approximately 39,000 meters of diamond drilling on the Omai property, leading to a mid-year resource expansion at Wenot, exploration success at satellite targets, a 708.1m 1.06 g/t Au mineralized drill intersection across the Gilt Creek gold deposit, and the discovery of Wenot’s down dip extension.
An updated NI 43-101 mineral resource estimate (MRE) showed 4.4 Moz Inferred gold at 1.95 g/t Au in 31.9Mt and 2.1Moz Indicated gold at 2.07 g/t Au in 69.6Mt, representing an increase of over 50% since February 2024. The Wenot open pit gold deposit resources increased by 96%, adding 2.2 Moz gold Inferred.
Drill intercepts from Wenot included:
Hole 25ODD-119
31.7 g/t Au over 7.5m
1.61 g/t Au over 36.4m
3.89 g/t Au over 13.2m
Hole 25ODD-102
28.04 g/t Au over 9.3m
8.90 g/t Au over 5.0m
3.36 g/t Au over 12.5m
4.55 g/t Au over 7.0m
The company confirmed Wenot expansion potential along strike, including new step out zones discovered of 11.07 g/t Au over 14.7 metres at East Wenot and 2.63 g/t Au over 27.5m at West Wenot.
Exploration of the down dip potential of the Wenot deposit led to the discovery of the shear’s extension at a depth of 700m below the known deposit, with multiple gold zones intersected. Drilling across the Gilt Creek deposit intersected multiple higher grade intervals, with near pervasive mineralization resulting in 708.1m averaging 1.06 g/t Au.
Omai Gold closed two private placements, resulting in a year-end cash position of C$57 million. They also submitted an Environmental Impact Assessment application, engaged ERM International to advance permitting, and completed formal Community Consultations.
Elaine Ellingham, President & CEO, said that 2025 was a successful and impactful year for Omai, with strong exploration results and progress on a 2026 updated PEA to include an expanded Wenot open pit deposit and the Gilt Creek underground deposit.
In 2026, the company is focused on the PEA, advancing permitting activities, delivering an updated mineral resource estimate, and commencing work towards a PreFeasibility or Feasibility Study.
In 2025 Omai Gold maintained an aggressive drill program with five drills turning much of the year. Drilling commenced January 13th and continued through to December 22nd. This resulted in approximately 39,000 metres of diamond drilling being completed in 2025 on the Omai Project in Guyana. Much of the program focused on testing the limits of the large Wenot shear-hosted deposit with the goal of expanding the resource along strike, on the flanks and at depth, as well as continuing to fill in gaps within the deposit. This met with great success as reflected in the surprisingly increased Mineral Resource Estimate announced in August. A strong positive outcome was that despite aggressive drilling, the limits to the Wenot deposit still remain open for further expansion. To boldly explore the depth potential of this large gold-mineralized Wenot shear system, the Company drilled a 2,014-metre drill hole (25ODD-122W) that first intersected 699m of the adjacent Gilt Creek gold deposit and then continued further and successfully discovered the down dip extension of the Wenot Shear Corridor at a depth of approximately 700m below the known Wenot deposit. Not only was the favourable geological structure and lithologies intersected but seven significant gold zones were also encountered. This “proof of concept” drill hole sheds a new light on the ultimate size potential of the Wenot deposit and opens the possibility for a multi-decade mine life. The upper part of this same hole provides strong support for the current Gilt Creek Mineral Resource Estimate with extensive gold mineralization along over 700m of core.
On August 25, 2025, Omai Gold announced a materially expanded NI 43-101 MRE on its flagship project. The updated estimate reflects the success of ongoing drilling programs and reinforces the strength of the Omai assets as a multi-million oz gold system with robust open pit grades at Wenot.
The Omai Property hosts two orogenic gold deposits: the shear-hosted Wenot Deposit and the adjacent intrusive-hosted Gilt Creek Deposit, which have a combined updated August 2025 MRE (over the February 2024 MRE) of:
2,121,000 ounces of gold (Indicated MRE), a 7% increase, averaging 2.07 g/t Au in 31.9Mt, and
4,382,000 ounces of gold (Inferred MRE), a 92% increase, averaging 1.95 g/t Au in 69.6Mt
Omai Gold made strides in permitting in 2025, progressing from an interim environmental permit received in late 2024 to engaging ERM International to assist in the Environmental Impact Assessment (EIA) application process. The application was submitted and formal community consultations were completed before year end with assistance from the EPA(Guyana).
To support its exploration and development objectives Omai Gold successfully closed a C$25.3 million (@$0.30/share) bought-deal private placement in February 2025, and in late October raised a further C$40 million (@$1.15/share). This greatly enhanced the Company’s financial capacity to execute expanded drilling, resource studies, permitting initiatives, and PEA work.
Looking ahead, Omai Gold is focused on delivering an updated MRE in Q1 2026 and a much expanded PEA in Q2 2026. The PEA is expected to integrate the expanded mineral resource base and revised pit optimization at Wenot and, for the first time, the Gilt Creek underground deposit.
Drilling is recommencing this week to continue exploring the limits of Wenot deposit, as well as working to upgrade the resources, work necessary for a Prefeasibility/Feasibility Study (PFS/FS). Certain promising exploration targets will be further drilled and modelled. Permitting will continue to advance with the defined Terms and Scope for the EIA expected early in the year.
