Omai Gold Files NI 43-101 Technical Report Supporting a Preliminary Economic Assessment Indicating After-Tax NPV5% of $4.0 Billion at a $3,600/oz Gold Price for its Omai Gold Project
Omai’s Guyana Gold Project PEA confirms a $4 billion net present value, 24% internal rate of return, and a 351,000 ounces per year production target.
Omai Gold Mines Corp. filed a National Instrument 43-101 Technical Report on October 2, 2026, supporting the Preliminary Economic Assessment (PEA) previously announced on August 19, 2026. The report covers the Wenot Open Pit and Gilt Underground Deposits in Guyana.
Key economic metrics remain unchanged from the August announcement, including a $4.0 billion after-tax net present value (NPV) at a 5% discount rate based on a base case of $3,600/oz gold, a 24% after-tax internal rate of return (IRR), and a 4.1-year payback period. The production profile targets an average of 351,488 ounces of gold per year over an 18-year mine life, with peak production of 435,667 ounces.
Capital requirements are outlined as $1.427 billion in initial capital and $928 million in sustaining and growth capital over the life of mine. Operating costs are projected at $1,501/oz in cash costs and $1,608/oz in All-In Sustaining Costs (AISC). The filing serves as a standard regulatory submission following the initial PEA release, confirming the technical and economic parameters previously disclosed to the market.
OMAI Gold Mines Corp. (OMG) filed a NI 43-101 document in mid-August 2026, a procedural regulatory follow-up that confirms the Preliminary Economic Assessment (PEA) metrics already absorbed by the market. The filing introduces no changes to the mine plan, capital expenditure, production targets, or cost structure.
The update serves as an incremental validation of the August PEA without altering the underlying investment thesis or valuation model. Consequently, the impact on the stock price is likely neutral to marginally positive, as the regulatory filing provides institutional compliance comfort, though the absence of new data limits upside momentum.
Omai Gold Mines Corp. is a 100%-owned exploration and development company focused on the Omai Gold Project in the Potaro Mining District of Guyana. The project is a past producer, having generated 3.8 million ounces of gold between 1993 and 2005. The flagship asset comprises two primary deposits: the Wenot open-pit deposit, which is shear-hosted and open to depth, and the Gilt underground deposit, which is intrusion-hosted.
Infrastructure advantages include an existing airstrip, tailings facilities, known metallurgy with 93–95% CIL recovery, and road connections to Georgetown and Linden. The company is transitioning from exploration to early development, with a focus on resource conversion, metallurgical optimization, and economic studies.
