Omar Gold Project Reports Multiple Zones Of Gold Mineralization

TORONTO – Omai Gold Mines Corp. reported on eight additional drill holes from the 2025 drilling program at its Omai Gold Project in Guyana, South America. Multiple zones of gold mineralization were intersected in each of these holes, most notably, central Wenot Hole 25ODD-150 intersected both 11.48 g/t Au over 10.2m and in a separate zone 10.65 g/t Au over 9.0m. The remaining 2025 drilling results are expected shortly.
A total of 79 diamond drill holes (35,300m) were completed on the Omai project in 2025. Of these, 31 were drilled at Wenot subsequent to the August 2025 Mineral Resource Estimate (MRE). These will contribute to an updated MRE that is underway and is expected to be completed in Q1. Drilling recommenced last week employing three of the five rigs that are currently on the property. Initially, drilling will continue at Wenot to focus on areas that have the potential to further expand the resource, including follow up on the new high grade zone discovered at the east end of Wenot (11.07 g/t Au over 14.7m) in late 2025. Drilling will also continue to test between depths of -300m to -450m depths, where many areas are still open, as well as starting drilling to upgrade the large Wenot Inferred MRE.
Holes 25ODD-145, 145w and 145w2 were all drilled from the south on section line 304980E, located in the central Wenot area. Hole 145 is the parent hole and 145w and 145w2 were both wedged from the parent hole. Hole 145w (previously released December 8, 2025) intersected multiple gold zones including 13.54 g/t Au over 13.3m (including 27.82 g/t Au over 6.2m) in the central Quartz Feldspar Porphyry (CQFP), a very continuous dike located at the contact between the sedimentary rocks on the south and the volcanic rocks on the north.
25ODD-145 first intersected four minor gold zones within the sedimentary sequence, then intersected 4.79 g/t Au over 14.5m within the CQFP and adjacent sheared diorite. Further downhole, within the Dike Corridor, a wide interval of smoky grey rhyolite with andesite and a diorite dike returned 2.61 g/t Au over 19.2m with a subinterval of 5.46 g/t Au over 5.8m. Further yet downhole, an interval of rhyolite with up to 2% pyrite and a high density of quartz veining with visible gold returned 2.26 g/t Au over 9.5m.
25ODD-145w2 is the second wedge of hole 145, drilled above hole 145w. The hole started in the sedimentary sequence on the south side and intersected four mineralized zones within the sediments, the best being 2.32 g/t Au over 3.9m. The CQFP was intersected from 373.0 to 385.1m down hole where it graded 1.65 g/t Au over 12.1m. Further downhole nine mineralized zones were encountered within the volcanics and Dike Corridor, including a quartz ankerite vein with visible gold that returned 15.74 g/t Au over 1.0m at 448.5m downhole. Intersections within rhyolite and diorite dikes include 4.24 g/t Au over 9.3m (including 12.25 g/t Au over 2.2m), as well as multiple minor zones including 1.03 g/t Au over 5.9m and 1.22 g/t Au over 4.1m.
Section 304980E: With the recent drilling on this section, multiple drill holes better outline the continuity of the gold zones. For example, on this section there are now six (6) intersections of the CQFP gold zone ranging from vertical depths of -200m to -400m. The additional holes and wedges were designed to reduce the drill spacing on all gold zones. This was particularly effective on the CQFP zones. These new and previous results highlight the vertical continuity of the gold mineralization within this very predictable, near-vertical, CQFP zone that occurs at the contact between the sediments and volcanics.
25ODD-149, located approximately 800m east of hole 145, was drilled from the south side of Wenot. Within the upper part of the hole, 0.37 g/t Au over 11.6m was intersected within the sediments only 111m downhole. The sedimentary sequence continued to 428.6m downhole, with the southern porphyry intruding at 302.5m to 305.4m and assaying 1.11 g/t Au over 2.9m. Four gold mineralized zones were intersected within the sediments, the best being 2.28 g/t Au over 19.7m associated with quartz veining and visible gold within spotted sediments with up to 3% pyrite. The CQFP returned 0.81 g/t Au over 10.1m on this section. North of the contact, in the volcanic sequence and Dike Corridor, abundant mineralization was encountered. A 42.0m wide interval averaged 1.58 g/t Au, which included several higher grade intervals the best being 4.63 g/t Au over 8.6m (including 15.95 g/t Au over 2.4m) in fine-grained andesite with quartz veins, pyrite and visible gold.
25ODD-150, collared 350m west of hole 149, was drilled from the south side of Wenot. The sedimentary sequence, intruded by several diorite dikes, continued downhole to 401.7m. Within this sequence, eight gold zones were encountered including 3.37 g/t Au over 8.3m in zones with intensely altered halos around quartz-ankerite veins with pyrite and visible gold. Additional zones within the sediments returned 1.18 g/t Au over 14.5m, 1.08 g/t Au over 11.3m, and 1.02 g/t Au over 8.5m. These can be expected to contribute to reducing the strip ratio along the southern side of the Wenot deposit. The central zone from 402m to 422m, consists of protomylonite and diorite and 2m of weakly altered CQFP. A transition zone from sediments to sheared protomylonite assayed 10.65 g/t Au over 9.0m, associated with visible gold-bearing quartz veins. Further downhole, the volcanic sequence hosts eight mineralized zones, the best being 11.48 g/t Au over 10.2m (including 28.54 g/t Au over 4.0m) in pyritic basalts with visible gold in milky quartz veins. Additional zones include 6.70 g/t Au over 2.5m, 1.1 g/t Au over 7.7m and 0.42 g/t Au over 21.0m far north within the volcanic sequence.
25ODD-150w is a wedge-up from hole 150 drilling from the south side of Wenot. The hole intersected several spots of visible gold in weakly altered sediments with seven minor gold zones, the best being 1.36 g/t Au over 6.8m. Not as impressive as hole 150, however again intersecting additional mineralization on the southern side of the deposit. The protomylonite and CQFP were only weakly mineralized in this hole assaying 1.72 g/t Au over 2.6m and 1.97 g/t Au over 1.3m, respectively. The best mineralized intercept was in a diorite dike within the Dike Corridor on the north side of the deposit, assaying 2.27 g/t Au over 4.2m.
25ODD-152 was collared on the south side of Wenot, 100m east of hole 145. No significant gold intervals were intersected within the sedimentary sequence and the protomylonite-CQFP assayed only 0.66 g/t Au over 9.4m. Only two minor zones were encountered within the volcanics, however the hole was terminated before the targeted depth was reached due to excessive azimuth deviation. Hole 152w was subsequently drilled, with assays pending.
West Wenot Drilling
25ODD-148 was collared from the south side, drilling north at the far west end of the Wenot deposit, well beyond previous historical mining. Results were as expected with minor mineralization in the saprolite followed by the sedimentary sequence that included veined diorite dikes before reaching the CQFP from 209.8m to 228.5m with up to 2% pyrite. A pyritic diorite dike with silica alteration and visible gold assayed 2.22 g/t Au over 12.5m from 115m downhole. This interval included a slightly higher-grade interval of 3.69 g/t Au over 3.1m from 120m downhole. The CQFP assayed only 0.62 g/t Au over 5.9m. Modelling of the main zones at this far west end of Wenot is ongoing. Additional drilling is needed in this area to locate the extensions of the nearby very wide and high-grade gold zones.
25ODD-151 was collared as a further westward step out from 25ODD-148, only 50m away. The hole intersected the sedimentary rocks down to 273m, then the central zone extended 23 m to 296m, then continued in volcanics to the end of hole at 361.4m. The best intercept encountered was 0.32 g/t Au over 4.8m in altered and sheared volcanics. Additional drilling is needed to locate the extensions of the nearby deeper gold zones.
