About Omai Gold Mines
Omai Gold Mines Corp. is a Canadian gold exploration and development company focused on rapidly expanding the two orogenic gold deposits at its 100%-owned Omai Gold Project in mining-friendly Guyana, South America. The Company has quickly established the Omai Gold Project as one of the fastest growing and well-endowed gold camps in the prolific Guiana Shield greenstone belt. In February 2024 the Company announced an updated NI 43-101 resource estimate1 of 29 million tonnes grading 2.15 g/t Au and containing 2.0 million ounces of gold (Indicated) and 31 million tonnes grading 2.26 g/t Au and containing 2.3 million ounces (Inferred), comprised of both the Wenot open pit deposit and the adjacent Gilt Creek underground deposit. An initial baseline Preliminary Economic Assessment 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$560m at a US$1,950/oz gold price.
Three drills have been turning most of 2025 focused on expanding gold resources at the Wenot deposit. Almost 30,000 metres of drilling have been completed since the 2024 resource estimate. An updated resource estimate is planned for Q3 2025 to be followed by an updated Preliminary Economic Assessment which would include an expanded Wenot open pit deposit and an underground mining scenario at Gilt Creek.
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.
