About Omai Gold Mines
Omai Gold Mines Corp. is a Canadian gold exploration and development company focused on its 100%-owned Omai Gold Project in mining-friendly Guyana, South America. The project hosts two adjacent orogenic gold deposits. An updated NI43-101 Mineral Resource Estimate of 4.4 million oz (Inferred) at 1.95 g/t Au (in 69.6Mt) plus 2.1 million oz (Indicated) at 2.07 g/t Au (in 31.9Mt) was announced August 25, 2025. This includes both the Wenot shear-hosted open pit deposit and the adjacent Gilt Creek intrusion-hosted underground deposit. A baseline Preliminary Economic Assessment (PEA) in April 2024, detailed an open pit-only development scenario and included only 45% of the Omai Gold Project resources with an NPV5% of US$556m at a US$1,950/oz gold price for production of 1.84 Moz. An updated PEA is underway to incorporate the new significantly expanded Resources in both the Wenot and Gilt Creek gold deposits, expected by year end.
Four diamond drills are turning focused at further exploring the limits of the very large 2.5km long Wenot deposit, testing the depth potential, as well as exploring nearby known higher grade gold occurrences for potential satellite deposits on this prolific past-producing gold camp.
The Omai Gold Mine produced over 3.7 million ounces of gold from 1993 to 20052, ceasing operations when gold was below US$400 per ounce. Omai benefits from being a brownfields site with some existing infrastructure and is connected by road to the two largest cities in Guyana, Georgetown and Linden.
