Omai Gold Mines Corp. reports exploration and project-advancement developments for its 100% owned Omai Gold Project in Guyana, South America. Company updates focus on drill assays and gold mineralization at the Wenot deposit, resource-definition work under NI 43-101, and technical study activity tied to the Wenot open pit and adjacent Gilt Creek underground deposit.
Recurring corporate news also includes mineral resource estimate updates, preliminary economic assessment work, permitting, metallurgy, tailings and baseline studies, as well as capital-structure items such as private placements and incentive stock option grants.
Omai Gold Mines (OMGGF) is mobilizing a sixth diamond drill to explore targets at its Omai Project in Guyana. An initial 5,000m program is planned, starting with eight holes at BBH, west of the Gilt deposit. Five drills continue infill and expansion drilling at Wenot following completion of the preliminary economic assessment.
BBH extends approximately 600m along strike. Late-2025 drilling intersected gold mineralization in all but one of seven widely spaced holes, including 20.33 grams of gold per tonne over 5.3m in hole 131 at a vertical depth of only 50m. Earlier trenching also returned gold-bearing samples. The company aims to identify a new near-surface deposit and is planning programs for additional exploration targets.
Omai Gold Mines (OMGGF) has filed a technical report supporting the preliminary economic assessment of its wholly-owned Omai Gold Project in Guyana. The report, dated October 2, 2026, covers the Wenot open pit and Gilt underground deposits. At $3,600/oz gold, the assessment projects a $4.0 billion after-tax net present value, discounted at 5%, and a 24% after-tax internal rate of return.
Projected payable production totals 6.327 million ounces over 18 years, averaging 351,488 ounces annually, with peak production of 435,667 ounces. Initial capital is estimated at $1.427 billion, plus $928 million in sustaining and growth capital. Average cash operating costs are $1,501/oz and all-in sustaining costs are $1,608/oz. At $4,200/oz gold, projected after-tax net present value rises to $5.5 billion and the return rate to 30%. Omai plans to expand and optimize the project while advancing toward a feasibility study.

Omai highlights a recently announced Preliminary Economic Assessment for its 100%-owned Omai Gold Project in Guyana, outlining a mine plan to produce 6.3 million ounces of gold over 18 years, averaging 351,000 ounces per year, and indicating a $4.0 billion net asset value at a $3,600/oz gold price base case.
Omai Gold (OTCQB: OMGGF) reported new assay results from 11 diamond drill holes at the Wenot Deposit within its 100%-owned Omai Gold Project in Guyana, part of an ongoing 50,000 m program. Hole 26ODD-193 in central Wenot intersected 5.12 g/t Au over 40.5 m, including 11.29 g/t Au over 10.4 m, within the Dike Corridor, while wedge hole 26ODD-197W in east Wenot cut 2.68 g/t Au over 40.7 m with multiple higher-grade sub-intervals. Five rigs are active; 74 holes totalling 35,149 m have been completed this year, and 77 additional holes (37,077 m) are not yet in the April 2026 Mineral Resource Estimate. According to Omai Gold, drilling over the past 16 months increased the Omai MRE by 86% and underpins a PEA mine plan averaging 351,000 oz Au per year over 18 years, with a stated NPV of $6.2 billion at 5% using a $4,500/oz gold price.
Omai Gold (OTCQB: OMGGF) reported a positive Preliminary Economic Assessment for its 100%-owned Omai Project in Guyana, combining the Wenot open pit and Gilt underground deposits. The study outlines an 18-year mine life with total payable gold production of 6.33 million ounces, averaging 351,488 oz/year and peaking at 435,667 oz.
At a base case gold price of $3,600/oz, the project shows an after-tax NPV5% of $4.0 billion, a 24% IRR, and a 4.1-year payback. Initial capital is estimated at $1.427 billion, with sustaining and growth capital of $928 million, for total life-of-mine capex of $2.396 billion. Average cash operating costs are projected at $1,501/oz and AISC at $1,608/oz, with average head grade of 1.35 g/t Au and 93% process recovery. Sensitivity analysis indicates after-tax NPV5% rising to $5.5 billion and IRR to 30% at $4,200/oz gold. The PEA is preliminary, relies on both Indicated and Inferred Mineral Resources, and does not declare Mineral Reserves.
