Omai Gold Mines drills 20.33 g/t gold over 5.3 metres at Omai Gold Project, Guyana
Omai Gold Mines Corp. [TSXV: OMG; OTCQB: OMGGF] reported assay results from the next phase of drilling at its 100%-owned Omai Gold Project in Guyana, South America. The current positive drilling results are from two near-surface exploration targets that were identified from trenching, geophysics and historical data. Assays are reported for 11 drill holes totalling 2,615 metres with six holes on the BBH target and 5 holes from the Camp Zone. A total of 64 drill holes have been completed to date this year on the Omai property, totalling 30,297 metres.
The deep hole 25ODD-122, testing the blue-sky potential at depth below the Wenot deposit, ended at a downhole depth 2,014 metres. It was successful in intersecting approximately 280m of the Wenot shear corridor at a depth of approximately 1,120 metres from surface or 600 metres below the known Wenot gold deposit. Assays are pending.
Five rigs are currently drilling on the Wenot deposit with the goal of completing an additional 8,000 metres before year end.
Highlights from the recent exploration holes include the BBH Target where Hole 25ODD-131 returned 20.33 g/t gold over 5.30 metres, including 35.61 g/t gold over 3 metres.
Camp Zone Target: Hole 25ODD-135 returned 2.72 g/t gold over 16.30 metres, including 9.05 g/t gold over 4 metres. Hole 25ODD-136 returned 2.05 g/t gold over 7.50 metres, including 11.32 g/t gold over 1 metre. Hole 25ODD-138 returned 0.85 g/t gold over 12.70 metres , including 1.32 g/t gold over 6 metres.
Elaine Ellingham, President & CEO, commented, “We are pleased to provide these exciting results from two of our exploration targets, both nearby the Wenot and Gilt Creek gold deposits. Although we have kept our focus on expanding the Wenot open pit deposit and driving forward to an updated Preliminary Economic Study with a much expanded Omai mine plan, we still believe that identifying and working to define additional satellite deposits will create further value to the project. A few of our exploration targets have evidence of higher grade mineralization and present possibilities for satellite pits that could positively impact early cash flow and overall NPV. With today’s results, we will further model these targets to guide additional drilling in these clearly prospective areas.”
“We are also pleased to announce that the deep hole 25ODD-122, drilled to test the blue sky potential of the Wenot deposit at depth successfully reached 2,014m. The hole flattened significantly, not unexpectedly but this allowed us to cross over 280m of the Wenot shear corridor at a vertical depth of about 1,120m, which is at least 600m below the deepest known extent of the Wenot deposit. Since we have identified the Wenot deposit along a 2.5 km strike length, this potential depth extension bodes well for the long-term potential of the project.
“Proving the shear extends this far to depth is a great win. We await assay results. Although the Omai Mineral Resource Estimate is quite sizeable, the geological extension to depth of the shear corridor that hosts the gold mineralization in the upper part of Wenot provides the possibility for an even longer mine life. Large-scale mine developments support long-term employment and sustainable communities. Omai is located 10km from the only road from Georgetown, the capital city of Guyana, to Brazil. Paving is well underway on this road and there are longer-term plans to establish this as an access to a major deep-water port planned on the coast of Guyana, east of Georgetown. This infrastructure would further benefit the Omai project.”
BBH Target Drill Results: A series of trenches and historical and recent drill holes identified significant near-surface high-grade gold mineralization. A series of flat-lying, saprolite-hosted ladder veins have also been observed in fresh rock within a nearby old adit (likely Anaconda, circa 1948). These ladder veins appear to occur between two northeast-trending structures. Drilling in 2021 intersected 1.7 g/t Au over 7.5m, and 3.15 g/t Au over 3.0m and six of eleven 2022 trench samples assayed over 6 g/t Au, including three that assayed over 10 g/t Au. Seven drill holes were recently completed along the interpreted 600m trend of this zone. Results for five of the seven holes have been received and results for the additional two holes are pending.
Most successful, hole 25ODD-131 tested the continuity of the shallow gold mineralization within a series of flat-lying quartz veins and veinlets identified in trenches located 100m to the west and also 300m to the northeast. Hole 131, drilled vertically, intersected a near-surface, high-grade zone of 20.33 g/t Au over 5.30m that included 35.61 g/t Au over 3.0m, at a depth of -50m. Another zone, although lower grade, returned 0.31 g/t Au over 6m at a depth of -86m.
This exploration further demonstrates significant near-surface gold mineralization in this area and additional drilling is warranted. These holes proved useful in better understanding the orientation and distribution of gold zones. A small near-surface high-grade resource in this area could be beneficial as a smaller, higher grade, satellite pit to a future mine plan for the larger Omai project. Results from an additional two holes in this area are pending.
The Camp Zone Target is located approximately 300-500m west of the Wenot deposit. The Wenot shear corridor extends through this area, with the expected Central Quartz Feldspar Porphyry (CQFP) occurring at the volcano-sedimentary contact, as usual. In this area, the shear corridor and CQFP appear slightly offset or splayed off the otherwise straight-line projection of the main Wenot shear.
Most significant new results from the Camp Zone include 2.72 g/t Au over 16.3m in hole 25ODD-135 at a depth of -115m, 6.81 g/t Au over 1m and 2.05 g/t Au over 7.5m in hole 25ODD-136 at a depth of -180m, and 0.85 g/t Au over 12.70m in hole 25ODD-138, also above -200m depth. In all of these cases, the mineralization occurred within the felsic dikes, believed to be correlated to the preferentially mineralized “Dike Corridor” seen at the main Wenot deposit, and to previously drilled gold-bearing felsic dikes along strike in the Camp Zone.
Drilling in the Camp Zone area has now identified mineralization occurring along a 450m strike. The best historical intersections include 1.56 g/t Au over 10.5m, 1.57 g/t Au over 7.5m, 3.0 g/t Au over 10.5m, and 5.75 g/t Au over 9.9m. More recently, the Company intersected 2.53 g/t Au over 9.9m in hole 22ODD-047, and early this year hole 25ODD-098 intersected 0.59 g/t Au over 10.5m and 0.42 g/t Au over 18.4m within the same horizon (News Release Dated March 27, 2025). Most of these intersections are at a depth of less than -150m, so attractive as a potential satellite pit. However, it is possible that with further drilling the Camp Zone may prove to be a continuation of the Wenot West gold mineralization, with a minor offset or deflection. Seven close-spaced holes were drilled in this area in September and assays are pending for two holes. Additional drilling will be planned once all results are received and reviewed.
Omai Gold Mines is focused on rapidly expanding the two orogenic gold deposits at its 100%-owned Omai Gold Project in mining-friendly Guyana. The company has established the Omai Gold Project as one of the fastest growing and well-endowed gold camps in the prolific Guiana Shield.
In August 2025, the company announced a 96% increase to the Wenot Gold Deposit NI 43-101 Mineral Resource Estimate (MRE) to 970,000 ounces of gold (Indicated) averaging 1.46 g/t Au, contained in 20.7 Mt and 3,717,000 ounces of gold (Inferred MRE) averaging 1.82 g/t Au, contained in 63.4 Mt.
This brings the global MRE at Omai, including the Wenot and adjacent Gilt Creek deposits, to 2,121,000 ounces of gold (Indicated MRE) averaging 2.07 g/t Au in 31.9 Mt and 4,382,000 ounces of gold (Inferred MRE) averaging 1.95 g/t Au in 69.9 Mt.
A baseline PEA announced in April 2024, contemplated an open pit-only development scenario and included less than 30% of the new Mineral Resource Estimate for Omai. Five drills are currently active on the property: at Wenot the focus is to optimize the upcoming PEA, to further test the limits of the deposit, including both east and west, and to commence upgrading the large Inferred MRE to Indicated.
Additional drilling will continue to explore certain known gold occurrences for possible near-surface higher-grade satellite deposits. An updated PEA is planned for H1 2026 to include the expanded Wenot open pit deposit and the adjacent Gilt Creek underground deposit. The Omai Gold Mine produced over 3.7 million ounces of gold from 1993 to 20052, ceasing operations when gold was below US$400/oz. The Omai site significantly benefits from existing infrastructure and is connected to the two largest cities in Guyana, Georgetown and Linden.
