Omai Gold Mines (OMG) investor relations material

Project overview and resource highlights

• Omai project in Guyana hosts two adjacent gold deposits with a combined resource of about 8 million oz, including 2.5 million oz indicated and 5.5 million oz inferred, both at robust grades for open pit and underground mining.

• Wenot deposit, the main focus, has been drilled extensively to 2.5 km length and 500 m depth, showing higher grades at depth and multiple vertical mineralized zones.

• The project benefits from existing infrastructure, including a paved highway, airstrip, and tailings facility, and is located in a mining-friendly jurisdiction with a clear permitting path.

• Historical production and strong metallurgical recoveries (92-95%) support the potential for a long-life mine, with the site previously contributing significantly to Guyana's GDP.

• The property is 100% owned, with simple land tenure and ongoing environmental permitting, and is well-positioned for interest from major gold producers seeking large, de-risked projects.

Exploration, development, and operational plans

• Aggressive drilling program with five rigs operating year-round, targeting both resource expansion and infill to support a preliminary economic assessment (PEA) and future feasibility study.

• The upcoming PEA, expected by early August, will outline a mine plan combining open pit (Wenot) and underground (Gilt Creek) operations, with a projected mine life of 16-20 years.

• Updated resource estimate anticipated in Q4, with ongoing drilling expected to add ounces and reduce mining costs and strip ratio.

• Processing plant capacity is being revised upward to 20,000-25,000 tons per day due to the scale of the deposit, with underground mining to follow after initial open pit years.

• Exploration focus remains on Wenot and its extensions, with step-out drilling at east Wenot and satellite targets along a 7-km shear zone.

Financials, valuation, and market positioning

• Well-financed with CAD 33 million in cash, a market cap of $1.2 billion U.S., and a share price around CAD 1.75; less than two million warrants outstanding and 8% options.

• Analyst consensus values the company at 0.2-0.3x NAV, with expectations for a re-rating as the PEA and further de-risking milestones are achieved.

• No major shareholders; largest is Mackenzie Funds at 6-7%, with strong institutional representation from U.S. and European funds.

• Inclusion in indexes like GDXJ is possible, which could further improve liquidity.

• Ongoing news flow expected from continuous drilling and resource updates through 2026, with improved assay turnaround anticipated.
