Core Viewpoint - Omai Gold Mines Corp. has significantly increased its Mineral Resource Estimate (MRE) for its Omai Gold Property in Guyana, with notable expansions in both the Indicated and Inferred resources at the Wenot and Gilt Creek deposits, positioning the project as one of the largest gold projects in the region [4][33]. Summary by Category Mineral Resource Estimates - The updated MRE includes Indicated resources of 2,121,000 ounces of gold at an average grade of 2.07 g/t Au, and Inferred resources of 4,382,000 ounces at an average grade of 1.95 g/t Au [3][9]. - The Wenot Deposit's Inferred MRE increased by 130% to 3,717,000 ounces at a grade of 1.82 g/t Au, while the Indicated MRE rose by 16% to 970,000 ounces at a grade of 1.46 g/t Au [3][4]. Deposit Details - The Omai Property hosts two main deposits: the Wenot Deposit, which utilizes both open pit and underground mining methods, and the Gilt Creek Deposit, which is primarily underground [2][4]. - The Gilt Creek Deposit has an Indicated MRE of 1,151,000 ounces averaging 3.22 g/t Au, and an Inferred MRE of 665,000 ounces averaging 3.35 g/t Au [8][17]. Economic and Technical Assumptions - The updated MRE is based on a gold price assumption of $2,500 per ounce, which allowed for a lower cutoff grade of 0.30 g/t Au compared to the previous 0.35 g/t Au [12][24]. - The MRE incorporates extensive drilling data, with 639 diamond drill holes and 12,028 assay results for the Wenot Deposit, and 46 drill holes with 7,056 assay results for the Gilt Creek Deposit [11][21]. Future Plans - The company plans to continue aggressive drilling to further expand the gold zones at both deposits and aims to advance towards a Feasibility Study by late 2026 [5][34]. - An updated Preliminary Economic Assessment (PEA) is expected to be completed in late 2025, incorporating the expanded MRE for both deposits [24][34].
