Omai Gold reports up to 95% gold recovery in Guyana project

Omai Gold Mines (TSX-V: OMG) has reported gold recoveries of 93% to 95% from phase one metallurgical testwork at its Omai Gold Project in Guyana. Results are based on 72 composite samples totalling 558 kilograms from the Wenot and Gilt deposits through SGS Canada’s Lakefield facility.  Gold extraction from fresh rock averaged 93% at a head grade of 1.0 grams per tonne gold and reached up to 95% at 3.20g/t gold.

Phase one testwork aimed to determine the amenability of the Wenot and Gilt deposits to a standard bottle leach and carbon-in-leach (CIL) circuit, in preparation for an upcoming preliminary economic assessment (PEA).

CEO Elaine Ellingham says the results of phase one testwork are “very favourable” and consistent with historical production results. “This will assist the project team, working towards the preliminary economic assessment, to assess sensitivity to initial capital expenditures, and support iterative engineering work to right-size the production capacity of the Omai Gold Project,” Ellingham says.

Omai Gold has completed five successive mineral resource estimates (MRE), with an April 2026 update showing Wenot indicated resources increased 49.8% to 1.45 million ounces at 1.59g/t gold. The company says follow-up testwork is planned for this year to advance project engineering in preparation for a 2027 Feasibility Study.

Ellingham says Omai expects to deliver the PEA within four to six weeks. Omai Gold Mines is focused on the expansion and development of its 100%-owned Omai Gold Project in Guyana.
