• Drill results include 3.08 g/t Au over 25.8m, 6.84 g/t Au over 9.5m, and 1.52 g/t Au over 37.5m from six holes at Wenot Deposit
• Deep exploration hole 25ODD-122 reaches 1,860m depth, intersecting Wenot shear corridor 605m below known deposit limits
• Results received after cutoff date for updated Mineral Resource Estimate will contribute to upcoming Preliminary Economic Assessment
• Four drill rigs active on property focusing on resource optimisation and deposit extension testing
• Exploration underway at Camp Zone and Blueberry Hill targets for potential satellite deposits

Omai Gold Mines Corp. (TSXV: OMG) (OTCQB: OMGGF) is a Canadian gold exploration and development company focused on expanding two orogenic gold deposits at its 100%-owned Omai Gold Project in Guyana, South America. The company operates within the Guiana Shield greenstone belt, where the historic Omai Gold Mine produced over 3.7 million ounces between 1993 and 2005. The project benefits from existing infrastructure and planned road connections to Georgetown and Linden.

Drilling Results from Wenot Deposit

Omai Gold reported assay results from six drill holes totalling 3,782 metres at the Wenot Deposit. Hole 25ODD-127 returned 3.08 g/t Au over 25.8 metres, including 17.06 g/t Au over 3.1 metres, and 1.52 g/t Au over 37.5 metres. Hole 25ODD-125 at West Wenot intersected 6.84 g/t Au over 9.5 metres, including 27.51 g/t Au over 1.2 metres.

The drilling targeted down-dip extensions of previously identified mineralised zones across multiple geological units including the Central quartz-feldspar porphyry zone and Dike Corridor. Results confirmed continuity of mineralisation in areas between existing drill holes, with intercepts correlating to zones identified in previous drilling programmes.

These results were completed after the cutoff date for the company's updated Mineral Resource Estimate announced in August 2025. According to the company, the intercepts will contribute to the updated Preliminary Economic Assessment expected in early Q1 2026. A total of 43 drill holes have been completed this year, totalling 23,500 metres.

Deep Exploration and Blue Sky Potential

The company continues drilling hole 25ODD-122, which has reached 1,860 metres depth in its test of potential mineralisation below the Wenot deposit. The hole intersected the targeted Wenot shear structural corridor at 1,598 metres downhole, at a vertical depth of approximately 1,100 metres below surface and 605 metres below the deepest known parts of the deposit.

The Wenot deposit consists of near-vertical gold zones within a 400-metre-wide shear corridor extending at least 2.5 kilometres along strike. The hole has continued within the shear corridor for 267 metres since intersection, with sampling commenced on the lower zone. Results from the upper portion of the hole, which intersected the Gilt Creek deposit, are pending analysis using metallic screening methods.

CEO Elaine Ellingham stated:

"Given the strike length and width of the Wenot deposit, should this deposit continue to greater depths and at economic grades, it could significantly increase the potential size and ultimate mine life of the Omai project."

Project Development Progress and Future Plans

Four drill rigs are currently active on the property with different objectives. At Wenot, drilling focuses on optimising the resource for the upcoming Preliminary Economic Assessment by targeting large gaps within the deposit to reduce strip ratio and upgrade Inferred Resources to Indicated category in the Central quartz-feldspar porphyry zone and northern Dike Corridor.

Two drills have been deployed to exploration targets while the Mineral Resource Estimate was being prepared. Five holes have been completed at the Camp Zone, located 500 metres west of current Wenot limits along the projected strike of the regional shear structure. Six holes have been completed at the Blueberry Hill trend, which extends 500 metres northeast towards the northern edge of the old Gilt Creek pit.

Ellingham commented:

"These zones have the potential to add higher grade mill feed early in the mine life, potentially improving project economics."

The company has indicated that work is underway on an updated Preliminary Economic Assessment.

Conclusion

Omai Gold has completed six drill holes at Wenot Deposit returning results including 3.08 g/t Au over 25.8m and 6.84 g/t Au over 9.5m. The deep exploration hole successfully intersected the target shear corridor 605 metres below known deposit limits. With four active drill rigs and an updated Mineral Resource Estimate recently announced, the company is advancing towards an updated Preliminary Economic Assessment expected in early Q1 2026. The technical report for the updated resource estimate will be filed within the coming weeks.
