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.
