Omai Gold Drills High-Grade Zones at Wenot:

11.48 g/t Au over 10.2m, 23.79 g/t Au over 3.8m and 4.79 g/t Au over 14.5m

Toronto, Ontario – (January 15, 2026) – Omai Gold Mines Corp. (TSXV: OMG) (OTCQB: OMGGF)

(“Omai Gold” or the “Company”) is pleased to announce assay results from eight additional drill holes

from the 2025 drilling program at its 100% owned 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.

Highlights* from the recent drilling include:

Central Wenot Drilling

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 (Figure 2). 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. Intercepts from -200m to the -400m depths are as follows:

1.65 g/t Au over 12.1m (hole 145W2),

13.54 g/t Au over 13.3m (hole 145W)**,

4.79 g/t Au over 14.5m (hole 145),

4.05 g/t Au over 20.6m (hole 12WED11)**,

3.13 g/t Au over 43.0m (hole 24ODD-078)**, and

2.31 g/t Au over 24.6m (hole 25ODD-107)**

(** previously released)

OMG.V - OMGGF: OTCQB News Release 2026/1/15

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.

OMG.V - OMGGF: OTCQB News Release 2026/1/15

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.

Quality Control

Omai maintains an internal QA/QC program to ensure sampling and analysis of all exploration work

is conducted in accordance with best practices. Certified reference materials, blanks and duplicates

are entered at regular intervals. Samples are sealed in plastic bags.

Drill core samples (halved-core) were shipped to Act Labs and some batches to MSALABS, both

certified laboratories in Georgetown Guyana, respecting the best chain of custody practices. At the

laboratory, samples are dried, crushed up to 80% passing 2 mm, riffle split (250 g), and pulverized to

95% passing 105 μm, including cleaner sand. Fifty grams of pulverized material is then fire assayed

by atomic absorption spectrophotometry (AA). Initial assays with results above 3.0 ppm gold are re-

assayed using a gravimetric finish. For samples with visible gold and surrounding samples within

deemed gold zones, two separate 250g or 500g pulverized samples are prepared, with 50 grams of

each fire assayed by atomic absorption spectrophotometry, with assays above 3.0 ppm gold being re-

assayed using a gravimetric finish. Certified reference materials and blanks meet with QA/QC

specifications.

ABOUT OMAI GOLD

Omai Gold Mines Corp. is a Canadian gold exploration and development company focused on rapidly

expanding the two orogenic gold deposits at its 100%-owned Omai Gold Project in mining-friendly

Guyana, South America. 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 Estimate1 (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.

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. An updated MRE and PEA are 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 2005 2, ceasing operations when

gold was below US$400 per ounce. The Omai site significantly benefits from existing infrastructure,

including an on-site airstrip, and is connected by road to the two largest cities in Guyana, Georgetown

and Linden.
