Omai Gold Mines announces high-grade and broad zones of gold from the first two holes at the Wenot Pit, including 16.0 meters of 9.0 g/t gold and 32.1 meters of 3.6 g/t gold

TORONTO, April 21, 2021 (GLOBE NEWSWIRE) — Omai Gold Mines Corp. (TSX VENTURE:OMG) (“Omai” or the “Company”) is pleased to announce that results from the first two holes of diamond core drilling at the Omai Project confirm that high-grade mineralization continues below the historically-producing Wenot Pit. The 5,000-meter drill program is focused on expanding the open-pit potential of the Wenot Pit that produced 1.8 million ounces of gold at 1.6 grams per tonne to a depth of 190 meters.

Highlights of the drill program:

• Holes 21ODD-001 and 21ODD-002 were drilled from the north side of the pit to test multiple mineralized structures below the Wenot Pit, on section lines approximately 350 meters apart.
• 21ODD-001 intersected multiple high-grade and thick intervals including 19.5 meters (m) of 2.2 grams per tonne (g/t) gold (Au), 13.5 m of 3.6 g/t Au, and 16 m of 9 g/t Au including 1 m of 127.7 g/t
  Au.
• 21ODD-002 intersected 32.1 m of 3.6 g/t
  Au including 26.7 g/t (0.4 m) and 25.7g/t (1 m) and an additional intersection further downhole of 18.4 m of 2.2 g/t Au.
• Mineralized zones are both in the basalt sequence as well as the sedimentary sequence close to the Wenot Shear.
• Drilling confirms high-grade mineralization extends at least 100 meters below the historical pit with indications it remains open at depth.

Mario Stifano, Chief Executive Officer of Omai Gold Mines, commented: “We are pleased with our assay results from the first two holes we drilled at Omai, that complement the assay results we announced in February. These results demonstrate that the grades and thicknesses of gold mineralization continue at least 100 to 150 meters below the historically-producing Wenot Pit, and remain open to depth and on strike. We look forward to updating our stakeholders with further results from our 5,000-meter drill program in the coming months.”

Holes 21ODD-001 and 21ODD-002 were drilled to confirm that gold mineralization continues at depth under the Wenot Pit. The higher grade zones are drilled on sections separated by 350 m, and are associated with sheared structures that host extensional veins. Gold, quartz-carbonate-sericite alteration and pyrite are associated with hornblende diorite intrusions within the basalt units under the pit. A second target type is the contact between the rhyolite dikes and basalts, which host highly sheared zones with strong iron and magnesium carbonate-sericite alteration and sulfides.

Gold grades are significant in both holes. The mineralization proximal to the Wenot Shear has also been confirmed by these holes with 21ODD-002 intersecting 18.4 m @ 2.2 g/t Au within the Lithic wacke close to the highly sheared and altered contact of the Wenot Shear.

Drilling is currently on the south side of the pit and drilling back to the north side. Songela, a well-established Guyanese company, is the drilling contractor. A single rig with two shifts is being used.

Sample collection, assaying and data management

​An experienced technician is stationed at the rig to record hole recovery, core orientation, and related geotechnical parameters. Core samples are collected at 1- to 2-meter intervals for assaying and consist of ½ core. Standards, blanks and duplicates are entered in the sample stream at regular intervals. Samples are sealed in plastic bags and shipped to the Actlabs certified laboratory in Georgetown, Guyana, respecting the best chain of custody practices. At the laboratory, samples are dried, crushed up to 80% passing 2 mm, riffle split (250 g), and pulverized to 95% passing 105 μm, including cleaner sand. 30 g of pulverized material is then fire assayed by atomic absorption (AA). Initial assays with results above 3,000 ppb gold are re-assayed with gravimetric finish. Standards and blanks are with QA/QC specifications.

About Omai Gold Mines Corp.

Early prospectors identified Guyana’s vast mineral wealth 130 years ago, and at the heart of the country’s gold mining history is the Omai mine: a multi-million-ounce deposit that was once South America’s largest producing gold mine. We’re building on this past success with new tools, relationships and vision to bring this under-explored gold district back to life, providing a unique opportunity for all stakeholders to participate in value creation.

Avalon Gold Exploration Inc., a wholly owned subsidiary of Omai Gold Mines Corp., holds a 100% interest in the Omai Prospecting License covering 4,590 acres, including the past producing Omai gold mine.
