ABOUT OMAI GOLD

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 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 Mineral Resource Estimate¹ ("MRE"), followed by the announcement of an initial baseline Preliminary Economic Assessment ("PEA"), both reported in an NI 43-101 Report filed in April 2024, available on www.sedarplus.ca. The 2024 PEA contemplated an open pit-only development scenario and included only 45% of the Omai Gold Project MRE. The Company announced an updated, significantly increased Mineral Resource Estimate on August 25, 2025 and is commencing the preparation of an updated PEA that is expected in early 2026. Four drills are currently active on the property: at Wenot the focus is to optimize the upcoming PEA, to further test the limits of the deposit, including both east and west, and to upgrade some of the large Inferred Resource to Indicated. Additional drilling will explore certain known gold occurrences for possible near surface higher-grade satellite deposits.

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. The Omai site significantly benefits from existing infrastructure and will soon be connected to the two largest cities in Guyana, Georgetown and Linden, via paved road.
