Omai Gold Mines drills 7.74 g/t gold over 13.5 metres at Wenot and commences drilling exploration target at Omai Gold Project, Guyana
Omai Gold Mines Corp. [TSXV: OMG; OTCQB: OMGGF] reported assay results from eight additional drill holes from the recent drill program at its 100%-owned Omai Gold Project in Guyana, South America.
Five of the eight holes were collared in West Wenot, two in Central Wenot and one at the east end of the Wenot deposit. All holes intersected multiple zones of gold mineralization. The objective of these holes was to fill gaps within the broader Wenot deposit, to convert some mineralized areas to the higher “indicated” confidence level and to provide further testing of the limits of the Wenot gold system. The holes at West Wenot showed continued significant gold mineralization within the southern sediments.
Five diamond drill rigs are now drilling on the Wenot deposit, all working on a series of holes at the northeast portion of Wenot. These are focused on the prolific Dike Corridor at depths between -150 to -400 metres (the DC holes), in areas not previously tested. As these holes are collared further to the north, they will also explore potential northern splays.
Early next week, one drill rig will be deployed to test an intriguing geophysical anomaly known as “the Handle” that corresponds to a magnetic high trending northeast off of the Wenot deposit. An additional drill rig will also commence an additional two holes stepping out on the East Wenot target area.
Highlights from the recent drilling include – Hole 25ODD-158: 7.74 g/t Au over 13.5 metres, including 28.03 g/t Au over 3.1 metres and 1.45 g/t Au over 44.4 metres, including 6.0 g/t Au over 3.6 metres.
Hole 25ODD-162: 6.30 g/t Au over 9.8m, including 37.31 g/t Au over 1.1m and 4.15 g/t Au over 6.7m.
Hole 26ODD-166: 10.02 g/t Au over 5.4m, 2.55 g/t Au over 10.5m and 1.48 g/t Au over 14.4m. Hole 25ODD-161: 5.06 g/t Au over 9.4m, including 26.96 g/t Au over 1.2m. Hole 26ODD-163: 2.61 g/t Au over 15.4m.
Hole 26ODD-164: 2.93 g/t Au over 10.0m, 2.78 g/t Au over 11.5m, including 7.41 g/t Au over 3.0m and 2.46 g/t Au over 11.0m.
Elaine Ellingham, President and CEO commented: “As these drill results continue to add to the confidence in Omai as a Tier 1 gold asset, we are advancing many aspects of work towards the next stages for the project. The company is expecting the completion of its updated Mineral Resource Estimate (MRE) within the next couple of weeks and the Preliminary Economic Assessment (PEA) is expected a couple months following completion of the MRE. We have already set our sights on the work that will advance us towards a Pre-Feasibility or Feasibility Study. Metallurgical work, tailings studies and the important permitting initiatives are front and centre. At the same time, we will continue our very aggressive drill program with a focus on upgrading the large Wenot resource, extending the limits and testing certain priority exploration targets.”
Central Wenot: Hole 25ODD-158 was drilled from the north side of the Wenot Deposit to evaluate down-dip extensions of mineralization across the wide Wenot shear corridor. The hole confirmed the depth continuity of the mineralization observed earlier in holes 153 and 153W (especially within felsic dikes).
Hole 158 intersected multiple visible gold occurrences associated with quartz-ankerite and quartz veining, shear zones and altered dikes within the northern volcanic sequence, including 7.74 g/t Au over 13.5m including 28.03 g/t Au over 3.1m.
Further downhole within the Dike Corridor, 1.45 g/t Au over 44.4m including 3.6 g/t Au over 6.0m was intersected in quartz veining within altered felsic dikes and the enclosing volcanics. The CQFP zone assayed 1.18 g/t Au over 10.6m. Only minor gold was encountered within the southern sediments in this area, the best being 1.79 g/t Au over 2.3m.
Hole 26ODD-164 was collared 120m in front of hole 158 on the same section line and also drilled to the south. Hole 164 provided good evidence of the upward continuity of zones intercepted by previous holes 25ODD-153 and 25ODD-158. In this hole, the Dike Corridor has 10 mineralized zones, the most notable of which are 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 included 7.4 g/t Au over 3m).
The Dike Corridor is very robust in this area and with the increased drilling density, the extent of this gold mineralization is becoming more apparent. The CQFP in hole 164 has 2 modest zones of 1.8 g/t Au over 1m and 2.7 g/t Au over 1.2m. A couple of gold zones within the sediments have 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 last intercept to the south, near the end of hole is 1.6 g/t Au over 5.3m within the southern porphyry (SPOR) zone. This SPOR is typically a narrow rock unit that persists along the full extent of the Wenot shear typically occurring about 125m south of the central contact that itself hosts the typically wide and well mineralized quartz-feldspar porphyry (CQFP).
East Wenot: Hole 25ODD-160 was drilled northward at the east end of the Wenot deposit. The dip of the contact between the volcanics and sediments is consistently steep to the north or sub-vertical along the full Wenot deposit. However, at this eastern end, there is evidence that the dip has rotated to the south.
Hole 160 illustrates this. This hole lies within a gap between holes 24ODD-82 (3.19 g/t Au over 22.8m and 3.65 g/t Au over 4.5m) and 22ODD-46 (1.85 g/t Au over 12.7m). In hole 160, a series of six gray to reddish gray felsic dikes occur within 50m of the central contact and CQFP. In this area, the Dike Corridor appears to converge with the central zone and it extends 50m from the CQFP to the north with up to 1-2% disseminated pyrite and quartz veining with some VG. Mineralized intervals within this 53m wide Dike Corridor include 2.64 g/t Au over 2.7m, 0.59 g/t over 4.2m, 1.01 g/t over 7.0m and 7.17 g/t Au over 1.5m.
West Wenot: Holes 25ODD-161 and -162 were drilled from the south side of the Wenot deposit. Hole 161 was drilled to explore the shallower extension of gold mineralization near the central contact above hole 25ODD-126 which returned 2.08 g/t Au over 18m, including 9.68 g/t Au over 1.5m in the CQFP. Hole 161 encountered the CQFP at the contact with 5.06 g/t Au over 9.4m (including 26.96 g/t Au over 1.2m) approximately 70m updip from the zones in hole 126 that assayed 2.08 g/t Au over 18.0m. 150m updip from the CQFP zone in hole 161, hole 20 intersected 1.28 g/t Au over 25.7m, this continuity of gold mineralization quite typical within the CQFP zone.
Further downhole in 161, several narrow mineralized intervals occur within the volcanics with up to 0.5% disseminated pyrite, the best assaying 8.47 g/t Au over 1.5m.
Hole 25ODD-162, collared 200m east of Hole 161, was also drilled from the south side of the Wenot Deposit. It intersected several discrete mineralized zones in the sediments with the best being 7.1 g/t Au over 1.2m associated with a diorite dike. The CQFP mineralization assayed 6.3 g/t Au over 9.8m (including 37.31 g/t Au over 1.1m) with several spots of VG. A number of gold zones within the Dike Corridor include 4.15 g/t Au over 6.7m and 4.56 g/t Au over 3m with VG and 2.11 g/t Au over 2.2m.
Hole 26ODD-165 was drilled at the far west end of Wenot to explore the potential to extend the deposit further to the west. Shallow in the northern volcanics, 0.86 g/t over 10.2m was intersected before the CQFP which assayed 0.61 g/t Au over 15.5m. The southern sediments host six minor gold zones, the best being 1.46 g/t Au over 3.0m. The zones clearly continue and deeper drilling may identify more robust mineralization, as the Wenot shear continues towards the Camp Zone.
Holes 26ODD-163, 26ODD-166 were drilled on the same section line, with hole 166 being 70m in front of (south) hole 163. Both were collared from the north side of Wenot. These holes tested across all of the Wenot shear corridor. Typical of the west end of Wenot, the major gold zones have migrated to the southern side of the contact, to be dominantly within the southern sediments. Both holes encountered significant visible gold, typical of this area of the deposit.
Hole 166 first encountered gold mineralization at a vertical depth of 150m with a zone running 10.02 g/t Au over 5.4m on the north side of the CQFP. Hole 163 intersected an impressive 2.61 g/t over 15.4m at a vertical depth of 260m that may represent the same zone as in hole 166.
Significant intercepts of gold mineralization were encountered, as expected, within the southern sediments in both holes: Hole 163’s sediment-hosted gold zones include 2.84 g/t Au over 6.4m, 1.97 g/t Au over 6.8m and 9.07 g/t Au over 1.0m. In hole 166 updip, the sediment zones include a number of zones along a 100m core interval including: 2.55 g/t Au over 10.5m, 1.48 g/t Au over 14.4m, 1.76 g/t Au over 6.0m, 1.37 g/t Au over 11.1m and 1.64 g/t Au over 4.2m. In all, hole 166 intersected over 69m of gold mineralization within a 175m downhole interval of sedimentary rocks, or roughly 40% of this sediment interval.
One drill rig is being deployed to test a prospective geophysics anomaly known as the “Handle”, that trends NE from the Wenot deposit. The Wenot deposit corresponds to a high magnetic anomaly related to magnetite content and the Handle is similarly a magnetic high. Historical blast hole data suggests northeast-trending structures play a role in the mineralization in some areas along the Wenot deposit. This geophysics anomaly conforms to this trend and presents an interesting drill target.
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 oz gold (Indicated) averaging 1.46 g/t Au, contained in 20.7 Mt and 3,717,000 oz 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 deposit, to 2,121,000 oz gold (Indicated MRE) averaging 2.07 g/t Au in 31.9 Mt and 4,382,000 oz gold (Inferred MRE) averaging 1.95 g/t Au in 69.9 Mt.
The company completed 39,000 metres of diamond drilling in 2025. An updated MRE is planned for Q1 2026 to be followed by an updated Preliminary Economic Assessment (PEA) in Q2, that will include the Wenot open pit deposit and the adjacent Gilt underground deposit. Three drills have commenced the 2026 drill program: at Wenot the focus is 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. 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 brownfields project benefits from known metallurgical recoveries, existing tailings facilities, and infrastructure, including an on-site airstrip, and road access, connecting to the two largest cities in Guyana, Georgetown and Linden.
