ABOUT OMAI GOLD

Omai Gold Mines Corp. holds a 100% interest in the past producing Omai gold property in Guyana which it is exploring for its resource potential to support large-scale, long-lived, gold production starting at shallow depths. The Company announced a Preliminary Economic Assessment ("PEA") on its Wenot deposit at Omai on April 4, 2024, supporting an open pit operation to produce 1.84 million ounces of gold over a 13-year period, with an NPV5% of US$556 million at a US$1950/oz gold price¹. An updated NI 43- 101 Mineral Resource Estimate ("MRE") announced February 8, 2024 for both the Wenot and Gilt Creek deposits includes 2.0 million ounces of gold (Indicated) and 2.3 million ounces (Inferred)¹. Once South America's largest producing gold mine, Omai produced over 3.7 million ounces of gold from two open pits between 1993 and 2005 before closing when the average gold price was less than US$400 per ounce. Historic mining only extended to 150-180 metres depth on part of the known deposits and considerable current resource remains at very shallow depths, including along the flanks of the historic pits. As a brownfields project, Omai benefits from good access and a wealth of historical data that provides knowledge of the geology, nature of the gold mineralization on the property, as well as metallurgy and historical recoveries. The Company's priorities through 2024 and 2025 are to: i) Drill to expand the resource base and overall property Mine Plan, ii) Enhance the economics beyond the initial baseline PEA, and iii) Advance permitting, engineering and baseline studies.
