Toronto, Ontario--(Newsfile Corp. - May 29, 2025) - Omai Gold Mines Corp. (TSXV: OMG) (OTCQB: OMGGF) ("Omai Gold" or the "Company") is pleased to announce additional assay results from its ongoing 2025 drill program, focused on expanding the large Wenot deposit at the Company's
Assays are reported for five holes totaling 3,117m drilled (Table 1). A total of 24 holes have been completed to date this year totalling 15,639m, having surpassed the original planned 15,000m program as results continue to extend the known limits of gold mineralization at Wenot (Figure 1). Results are pending for an additional 12 holes (Table 2). Drilling continues with two rigs on Wenot and a third rig on a long Gilt Creek-Wenot drill hole (see News Release May 23, 2025). An updated NI 43-101 MRE has commenced and is expected to be completed in the third quarter of 2025.
Highlights include:
- Hole 25ODD-116
- 2.63 g/t Au over 27.5m
- Includes 4.68 g/t Au over 9.5m
- Includes 4.68 g/t Au over 9.5m
- 2.63 g/t Au over 27.5m
- Hole 25ODD-106
- 2.64 g/t Au over 21.0m
- 1.62 g/t Au over 16.5m
- 1.18 g/t Au over 17.1m
- Hole 25ODD-111
- 4.87 g/t Au over 9.5m
- 1.45 g/t Au over 9.9m
- Hole 25ODD-109
- 2.37 g/t Au over 15.0m
- 1.73 g/t Au over 6.7m
Elaine Ellingham, President & CEO, commented: "We are excited that we are still discovering new gold zones around our large Wenot deposit. The 27.5m intersection averaging 2.63 g/t Au in hole 25ODD-116 is within the volcanics to the north of the main contact zone, and about 100m north of any signficant known gold zones at West Wenot. It effectively extends the known gold mineralization to the northwest and opens the possibility of extensions both east and west into areas that have seen little drilling. We have already started an additional drill hole to explore along strike of this new zone. The balance of today's drill results are yet another batch of encouraging and high-grade step outs, including 2.64 g/t Au over 21.0m and 4.87 g/t Au over 9.5m, which continues to bode well for the updated MRE anticipated next quarter. The long Gilt Creek-Wenot hole that commenced last week is progressing well and just passed through the diabase dike and entered the Gilt Creek intrusion yesterday morning."
West Wenot:
A number of holes have been drilled in West Wenot in 2025, an area which lies outside of any previous mining, other than for surficial saprolite. A significant part of the Wenot MRE lies within this area that management believes could be suitable for a starter pit in a production scenario. Holes 25ODD-109/109W and hole 25ODD-116 are additional holes that were designed to test the continuity of the deeper gold zones to surface, which could contribute to a low-strip resource.
Hole 25ODD-116 (Figure 2) was drilled from the south side of West Wenot at a similar easting as holes 108 and 109, which were drilled from the north. Hole 25ODD-116 was primarily targeting near-surface extensions of known gold zones in the southern sediments and in the central quartz feldspar porphyry dike "CQFP". While gold mineralization dominantly occurs in the volcanics on the northern side of the central contact for much of the Wenot deposit, at West Wenot, mineralization has been dominantly identified at the contact zone (CQFP) and most prominently within the southern sedimentary sequence. Hole 25ODD-116 successfully intersected the shallow gold mineralization in the southern sediments, with four intervals between 100 and 200m depth, including 1.15 g/t Au over 8.3m (with 4 occurrences of visible gold). However, hole 25ODD-116 was continued in order to test the unexplored area to the north. This paid off with the intersection of a new gold zone of 2.63 g/t Au over 27.5m (including 4.68 g/t Au over 9.5m), approximately 120m north of the central contact in the volcanics at a vertical depth of just over 300m. Some of the impressive core is shown in Figure 3. This is a promising new discovery, and the Company has already started a follow-up drill hole to explore the size potential.
Hole 25ODD-109/109W (Figure 2) was drilled from the north side of West Wenot targeting shallow near-surface mineralization where a potential "starter pit" would benefit from a low strip ratio given the lack of historical mining in the area. Hole 109 was drilled to a total depth of 399m with a wedge at 98.5m downhole. It successfully intersected 21 separate occurrences of visible gold and, as expected, mostly within the sedimentary rocks south of the central contact. At a shallow depth of approximately 50m below surface, a 15.0m interval of 2.37 g/t Au included 4 occurrences of visible gold within a highly altered rhyolite dike with an extensive quartz vein stockwork. The nearby central quartz feldspar porphyry ("CQFP") at the main volcanic-sediment contact, hosts 1.73 g/t Au over 6.7m. Within the southern sediments, as is typical of this part of the deposit, hole 109 intersected several gold zones including 2.0 g/t Au over 7.5m, 1.25 g/t Au over 5.0m, and 2.06 g/t Au over 2.5m.
Central Wenot:
Hole 25ODD-106 (Figure 3) was drilled from the south, at a similar easting to hole 23ODD-064 (see News Release August 22, 2023) and approximately 100m west of hole 25ODD-103 (see News Release May 12, 2025) - both drilled from the north side. The hole was wedged part way down and had a final depth of 609m. Hole 25ODD-106 intersected broad zones of gold mineralization within the southern sedimentary sequence, including 1.59 g/t Au over 9.2m, 1.18 g/t Au over 17.1m, and 2.0 g/t Au over 5.5m. The hole went on to intersect 2.64 g/t Au over 21.0m, 1.01 g/t Au over 10.5m, and 1.62 g/t Au over 16.5m - all within the within the most prolific historically mined zone, known as the "Dike Corridor". The Dike Corridor is one of five dominant subparallel, near-vertical gold zones that comprise the large 2.5km long Wenot deposit. Lying within the broader Wenot Shear, the roughly 100-200m wide Dike Corridor is typically 25-100m north of the central volcanic-sedimentary contact, that itself hosts gold mineralization within a persistent quartz feldspar porphyry unit. The Dike Corridor is comprised of a series of felsic and diorite dikes that intruded into the volcanic sequence and were later subjected to varying degrees of shearing, alteration and stockworks of quartz veining.
Hole 25ODD-111 was drilled from the north at Central Wenot, targeting 75m down-dip from hole 21ODD-002 and 100m east of hole 24ODD-085. The hole intersected 4.87 g/t Au over 9.5m within the northern volcanics at a depth of approximately 200m from surface. This intersection is within the northern flank of the 2024 MRE pit shell, but ~50m below the 2024 PEA pit shell. Our 2025 drilling has continued to focus on exploring the limits of the Wenot gold system and this hole again demonstrates continued success. The hole continued on to intersect 1.45 g/t Au over 9.9m within the Dike Corridor, and 0.99 g/t Au over 16.4m at the central QFP at the main sediment-volcanic contact.
Hole 25ODD-104 was drilled from the south at Central Wenot along a similar easting to hole 24ODD-091 and 021 drilled from the north. Within the southern sedimentary rock sequence, the hole intersected 0.79 g/t Au over 27.5m at a depth of approximately 250m from surface. The central Quartz Feldspar Porphyry dike at the central contact assayed 0.87 g/t Au over 22.7m, that included a 5.5m interval grading 2.17 g/t Au. Further downhole 2.04 g/t Au over 8.9m was intersected in altered volcanics, close to the main contact, and 0.72 g/t Au over 20.5m was intersected within the Dike Corridor at a depth of approximately 400m.
