ABOUT OMAI GOLD

Omai Gold Mines Corp. holds a 100% interest in the Omai Prospecting License that includes the past-producing Omai Gold Mine in Guyana, and a 100% interest in the adjoining Eastern Flats Mining Permits. The Company announced a Preliminary Economic Assessment ("PEA")¹ on its Wenot Deposit at Omai in April 2024, showing an open pit operation to produce 1.84 million ounces of gold over a 13-year period, with an NPV_5% of US$556 million at a US$1,950/oz gold price. This baseline PEA incorporates only 45% of the property's MRE and management believes that with additional work the mine plan can be significantly expanded, the economics enhanced, and the open pit resources further increased. An updated NI 43-101 Mineral Resource Estimate ("MRE")¹ of 2.0 million ounces of gold (Indicated) and 2.3 million ounces (Inferred) reflects a notable increase as a result of 2023's successful drilling. Once South America's largest producing gold mine, Omai produced over 3.7 million ounces of gold between 1993 and 2005². Mining ceased at a time when the average gold price was less than US$400 per ounce. As a brownfields project, Omai benefits from good road access and a wealth of historical data that provides knowledge of the geology and gold mineralization on the Property, as well as metallurgy, historical processing recoveries and many other relevant mining parameters.

¹ NI43-101 Technical Report dated May 21, 2024 "UPDATED MINERAL RESOURCE ESTIMATE AND PRELIMINARY ECONOMIC ASSESSMENT OF THE OMAI GOLD PROPERTY, POTARO MINING DISTRICT NO.2, GUYANA" was prepared by Eugene Puritch, P.Eng., FEC, CET, President of P&E Mining Consultants Inc. is available on SEDAR+ and on the Company's website.
