Omai Gold Mines Company (TSXV: Oh, my God; OTCCP: Oh, my God) Assay results have been reported from eight additional drill holes from the recent drilling program at the 100% owned Omai Gold Project in Guyana, South America.
Five of the eight holes in the west of the Waynut, two in the center of the Waynut and one at the eastern end of the Waynote deposits are cordoned off. All holes intersect multiple zones of gold mineralization. The aim of these holes was to fill gaps within the wider Wenot deposit, to convert some of the mineralized areas to a higher confidence ‘indicated’ level and to provide further testing of the boundaries of the Wenot gold system. Holes at West Wynot showed continued significant gold mineralization within the southern deposit.
Five diamond drilling rigs are now drilling at the Wenot deposit, all working on a series of holes in the northeastern part of Wenot. These tests are focused on the abundant Dike Corridor at depths ranging from -150 to -400 meters (DC holes), in areas that have not been previously tested. Since these holes are ringed to the north, they will also explore potential northern breaks.
Early next week, a single drilling rig will be deployed to test an interesting geophysical anomaly known as “the knob” which corresponds to a high magnetic trend northeast of the Wenot deposit. An additional drilling rig will also begin drilling two additional holes in the target area of East Wenot.
Recent drilling highlights – Hole 25ODD-158 include: 7.74 g/t Au at a depth of 13.5 metres, including 28.03 g/t Au at a depth of 3.1 metres, and 1.45 g/t Au at a depth of 44.4 metres, including 6.0 g/t Au at a depth of 3.6 metres.
Hole 25ODD-162: 6.30 g/t Au over 9.8 m, including 37.31 g/t Au over 1.1 m and 4.15 g/t Au over 6.7 m.
Hole 26ODD-166: 10.02 g/t Au over 5.4 m, 2.55 g/t Au over 10.5 m, and 1.48 g/t Au over 14.4 m. Hole 25ODD-161: 5.06 g/t Au over 9.4 m, including 26.96 g/t Au over 1.2 m. Hole 26ODD-163: 2.61 g/t Au over 15.4 metres.
Hole 26ODD-164: 2.93 g/t Au over 10.0 m, 2.78 g/t Au over 11.5 m, including 7.41 g/t Au over 3.0 m and 2.46 g/t Au over 11.0 m.
Eileen Ellingham, President and CEO, commented: “As these drilling results continue to reinforce confidence in Omai as a Tier 1 gold asset, we are advancing several aspects of the work towards the next phases of the project. The company expects to complete its updated Mineral Resource Estimate (MRE) within the next two weeks, and a Preliminary Economic Assessment (PEA) is expected to be conducted two months after the MRE is completed. We have already set our sights on the work that will move us towards a pre-feasibility or feasibility study. Mineral work, tailings studies and important permitting initiatives are front and center. At the same time, we will continue our very aggressive drilling program with a focus on upgrading the large Wenot resource, expanding the frontier and testing some priority exploration targets.“
Central Wenot: Hole 25ODD-158 It was drilled from the northern flank of the Wenot deposit to evaluate down-dip extensions of mineralization across the broad Wenot shear corridor. The hole confirmed the continuity of the depth of mineralization previously observed in holes 153 and 153W (particularly within the felsic dikes).
Hole 158 intersects numerous visible gold occurrences associated with quartz, ancrete and quartz veins, shear zones and altered dikes within the northern volcanic sequence, including 7.74 g/t gold over 13.5 metres, including 28.03 g/t gold over 3.1 metres.
Further downhole within the Dike Corridor, 1.45 g/t Au over 44.4 meters including 3.6 g/t Au over 6.0 meters were intersected in quartz veins within altered felsic dikes and surrounding volcanics. The CQFP zone was assessed at 1.18 g/t Au over 10.6 m. Only a small amount of gold has been found in the southern deposits in this area, the best being 1.79 g/t gold at a depth of 2.3 metres.
Hole 26ODD-164 was cordoned off 120 meters in front of Hole 158 on the same section line and was also drilled to the south. Hole 164 provided good evidence of upward continuity of areas intercepted by earlier holes 25ODD-153 and 25ODD-158. In this hole, the Dike Corridor contains 10 mineralized zones, most notably 2.93 g/t Au over 10.0m with VG, 2.12 g/t Au over 9.0m with VG and 2.78 g/t Au over 11.5m (which includes 7.4 g/t Au over 3m).
The Dike Corridor is very strong in this area, and as drilling density increases, the extent of gold mineralization becomes more apparent. The CQFP in hole 164 contains two modest zones of 1.8 g/t Au over 1 m and 2.7 g/t Au over 1.2 metres. Some gold zones within the deposit contain VG and the best intercepts are 2.4 g/t Au over 10m (including 4.43 g/t Au over 4m) and 2.46 g/t Au over 11m (including 16.5 g/t Au over 1.2m). The final intersection to the south, near the end of the hole is 1.6 g/t gold over 5.3 meters within the Southern Porphyry Zone (SPOR). This SPOR is a narrow rock unit that continues along the full extent of the Wenot shear occurring typically about 125 meters south of the central contact which itself hosts a broad, well-mineralized quartz-feldspar (CQFP) porphyry.
East Wenot: Hole 25ODD-160 was drilled northward at the eastern end of the Wenot deposit. The dip in contact between the volcanics and the deposits is consistently steep to the north or nearly vertical along the entire length of the Wenot deposit. However, at this eastern end, there is evidence that the dip has turned towards the south.
Hole 160 demonstrates this. This hole is located within a gap between holes 24ODD-82 (3.19 g/t Au over 22.8 meters and 3.65 g/t Au over 4.5 metres) and 22ODD-46 (1.85 g/t Au over 12.7 metres). In hole 160, a series of six gray to reddish-gray felsic dikes are located 50 m from the central contact and the CQFP. In this area, the Dike Corridor appears to converge with the central zone and extends 50 m from the CQFP to the north with up to 1-2% disseminated pyrite and quartz veins with some VG. Mineral intervals within the 53m-wide dam passage include 2.64 g/t Au over 2.7m, 0.59g/t Au over 4.2m, 1.01g/t Au over 7.0m, and 7.17g/t Au over 1.5m.
West Wynot: Holes 25ODD-161 and -162 were drilled from the south side of the Wynot deposit. Hole 161 was drilled to explore the shallow extension of gold mineralization near the central contact above hole 25ODD-126 which returned 2.08 g/t gold over 18 metres, including 9.68 g/t gold over 1.5 meters at CQFP. Hole 161 encountered CQFP in contact with 5.06 g/t Au over 9.4 m (including 26.96 g/t Au over 1.2 m) approximately 70 m from areas in hole 126 that assayed 2.08 g/t Au over 18.0 m. Up 150m of the CQFP zone in hole 161, hole 20 intersected 1.28 g/t Au at 25.7m, and this continuity of gold mineralization is quite typical within the CQFP zone.
Further downhole at 161, several narrow intervals of intravolcanic mineralization occur with up to 0.5% disseminated pyrite, best assayed 8.47 g/t Au over 1.5 metres.
Hole 25ODD-162, located 200 meters east of hole 161, was also drilled from the south side of the Wenot deposit. Several separate mineralized zones intersected the deposit, the best of which was 7.1 g/t gold over 1.2 meters associated with a diorite dike. CQFP mineralization measured 6.3 g/t Au over 9.8 m (including 37.31 g/t Au over 1.1 m) with several zones of VG. A number of gold zones within the Dike Corridor include 4.15 g/t Au over 6.7m, 4.56 g/t Au over 3m with VG and 2.11 g/t Au over 2.2m.
Hole 26ODD-165 It was drilled at the westernmost end of the Wenot to explore the possibility of extending the deposit to the west. Shallow in the northern volcanoes, 0.86 g/t was intersected at 10.2 m before CQFP sampled 0.61 g/t at 15.5 m. The southern deposit contains six small gold zones, the best of which is 1.46 g/t gold at a depth of 3.0 metres. The zones are clearly continuous and deeper drilling may identify more robust mineralization, with continued Wenot shearing towards the camp zone.
Holes 26ODD-163, 26ODD-166 They were drilled on the same section line, with Hole 166 being 70 meters in front of (southern) Hole 163. They were cordoned off on the north side of the wynot. These holes were tested throughout the Wenot shear corridor. As at the western end of Wynot, the main gold zones have migrated to the south side of the contact, being dominant within the southern deposits. Both holes encountered a large amount of visible gold, which is characteristic of this area of the deposit.
Hole 166 first encountered gold mineralization at a vertical depth of 150 meters with a zone grading 10.02 g/t gold over 5.4 meters on the north side of the CQFP. Hole 163 intersected 2.61 g/t over 15.4 meters at a vertical depth of 260 metres, which would represent the same area as hole 166.
Significant intercepts of gold mineralization were encountered, as expected, within the southern deposits in both holes: the deposit-hosted gold zones in hole 163 include 2.84 g/t gold at 6.4 m, 1.97 g/t gold at 6.8 m, and 9.07 g/t gold at 1.0 m. In hole 166 updip, the deposit zones include a number of zones along a core interval of 100 metres, including: 2.55 g/t Au over 10.5 m, 1.48 g/t Au over 14.4 m, 1.76 g/t Au over 6.0 m, 1.37 g/t Au over 11.1 m and 1.64 g/t Au over 4.2 m. In total, hole 166 intersected more than 69 meters of gold mineralization within 175 meters downhole of sedimentary rock, or approximately 40% of this sedimentary interval.
One drilling rig is being deployed to test a potential geophysical anomaly known as the ‘Knob’, which trends to the northeast of the Wenot deposit. The Wenot deposit corresponds to a high magnetic anomaly related to the magnetite content and the handle is similarly magnetic high. Historical blast hole data indicate that northeast-oriented structures play a role in mineralization in some areas along the Wenot deposit. This geophysical anomaly is consistent with this trend and represents an interesting drill target.
Omai Gold Mines is focused on the rapid expansion of provenance 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 richest gold camps in the prolific Guiana Shield region.
In August 2025, the company announced a 96% increase in the Mineral Resource Estimate (MRE) for the Wenot Gold Deposit NI 43-101 to 970,000 ounces of gold (indicated) averaging 1.46 g/t Au, contained in 20.7 million tonnes and 3,717,000 ounces of gold (inferred MRE) averaging 1.82 g/t Au, contained in 63.4 mt, taking the global MRE at Omai, including the Wenot deposit and adjacent gilt deposits, to 2,121,000 ounces of gold (indicated MRE) averaging 2.07 g/t Au at 31.9 mt and 4,382,000 ounces of gold (inferred MRE) averaging 1.95 g/t Au at 69.9. metric tons.
The company completed 39,000 meters of diamond drilling in 2025. A drilling update is scheduled for the first quarter of 2026, followed by an updated preliminary economic assessment (PEA) in the second quarter, which will include the open-pit Wenot deposit and the adjacent underground Gilt reservoir. Three exercises have begun the 2026 drilling program: At Wenot, the focus is to continue testing the deposit boundaries, including east and west, and begin upgrading the large inferred to indicated MRE.
Additional drilling will continue to explore some of the known gold deposits for high-grade, near-surface satellite deposits. The Omai Gold Mine produced more than 3.7 million ounces of gold from 1993 to 2005.2Operations were halted when gold was below US$400 per ounce. The Omai brownfields project takes advantage of known mineral recoveries, existing tailings facilities, and infrastructure, including an on-site airstrip and road access, linking Guyana’s two largest cities, Georgetown and Linden.
