en.Wedoany.com Reported - Omai Gold Mines (TSX-V: OMG) has achieved gold recovery rates of 93% to 95% in the first phase of metallurgical testing at its Omai Gold Project in Guyana.

The tests were based on 72 composite samples totaling 558 kilograms from the Wenot and Gilt deposits, conducted at SGS Canada's Lakefield facility.

Gold extraction from fresh rock averaged 93% at a grade of 1.0 g/t and reached 95% at a grade of 3.20 g/t.

The first phase of testing aimed to evaluate the suitability of the Wenot and Gilt deposits for standard bottle roll and carbon-in-leach (CIL) circuits, providing data for the upcoming preliminary economic assessment (PEA).

CEO Elaine Ellingham stated that the first-phase results were "very favorable" and consistent with historical production data.

Ellingham said this will help the project team advance the preliminary economic assessment, evaluate initial capital expenditure sensitivities, and support iterative engineering work to reasonably determine the capacity of the Omai Gold Project.

Omai Gold has completed five consecutive mineral resource estimates (MREs), with an April 2026 update showing a 49.8% increase in Wenot indicated resources to 1.45 million ounces at a grade of 1.59 g/t gold.

The company plans follow-up testing this year to advance project engineering in preparation for a feasibility study in 2027.

The company has also started a large-diameter diamond drill hole at Gilt to evaluate crushing and grinding parameters for mill design, with a similar hole to begin shortly at Welt.

Ellingham said Omai expects to submit the preliminary economic assessment within four to six weeks.

Omai Gold Mines is focused on the expansion and development of its wholly-owned Omai Gold Project in Guyana.
