Omai Gold Drills 5.12 g/t Au over 40.5m and 2.68 g/t Au over 40.7m at Wenot
Omai Gold Drills 5.12 g/t Au over 40.5m and 2.68
g/t Au over 40.7m at Wenot
Toronto, Ontario--(Newsfile Corp. - September 1, 2026) - Omai Gold Mines Corp. (TSXV: OMG)
(OTCQB: OMGGF) ("Omai Gold" or the "Company") is pleased to announce assay results from eleven
additional diamond drill holes from the ongoing 50,000 metre ("m") drilling program at its 100% owned
Omai Gold Project in Guyana, South America. Each drill hole on the Wenot Deposit encountered multiple
gold zones. Hole 26ODD-193 in central Wenot intersected 11 discrete gold zones including 5.12 g/t Au
over 40.5m, which included 11.29 g/t Au over 10.4m at a vertical depth of between -260 to -290m within
the prolific Dike Corridor. Given that an economic cut-off grade of 0.3 g/t Au was applied to the Wenot open
pit deposit, these intersections are very significant.
Five rigs continue to drill at Omai. To date this year, 74 drill holes have been completed, totalling 35,149m.
Hole 26ODD-208, testing the depth potential of the Gilt Deposit, was completed at a downhole depth of
1,438m (~1,200m vertical depth). Samples from the upper part of the hole have been submitted for
assaying. Certain selected whole core samples are being prepared for mineral processing testing.

Elaine Ellingham, President & CEO, commented: "We are pleased to deliver further strong drill results from
Wenot. Drilling is expected to continue through to mid-December with the five rigs. Our Preliminary
Economic Assessment ("PEA")1 recently announced for the Omai Project, exceeded our long-established
target for a 250,000 to 300,000 ounce per year mine, as we delivered a mine plan for production averaging
351,000 oz per year over an 18-year mine life. Our drilling continues to be highly effective; over the past 16
months, we increased the Omai Mineral Resource Estimate (MRE) by 86%, allowing us to reach this much
larger mine plan and also a much lower than market-anticipated strip ratio. With a larger mine comes
increased upfront capital requirements, however, this optimizes economics and further establishes Omai
as one of the largest undeveloped gold projects in South America. With the current gold price around
$4,500/oz, the Omai PEA supports a net present value (NPV) of $6.2 billion, at a 5% discount. With this
strong PEA, we are on a clear trajectory for advancing Omai to the next milestones.
Today's drill results continue to demonstrate the potential for the Wenot open pit deposit to continue to
expand, while we upgrade the resources and better delineate the very wide and robust zones, particularly
in the dike corridor. These new drill results also reinforce our confidence in future expansion of the gold
zones on the southern side of the Wenot deposit, within the sedimentary sequence. Significant new,
sediment-hosted gold zones announced include: 4.61 g/t Au over 9.4 m (hole 198), 1.67 g/t Au over 16.9m
(hole 193), 6.54 g/t Au over 3.0m (hole 194), and 2.0 g/t Au over 9.8m. To date, we have completed an
additional 77 holes, totalling 37,077m, that are not included in the April 2026 MRE. The results from this
program will contribute to our next resource update, planned for completion before year end, and support
our objective of advancing the project towards a feasibility study."
The current results from the Wenot deposit can be expected to contribute to both upgrading some of the
large inferred resource while continuing to expand several of the gold zones. The geological model was
refined for the April MRE update, after significant additional drilling. Subsequent drilling continues to show
that the model is performing well.
CENTRAL WENOT
26ODD-188 (305130E) is an upper cut to holes 21ODD-003 and 26ODD-183. The upper portion of hole
188 intersected two main gold zones within the dike corridor, including 4.14 g/t Au over 6.7m and 1.30 g/t
Au over 7.6m. These correlate to the intercept in hole 183 of 2.96 g/t Au over 14.3m approximately 40m
below.
The hole continued into the CQFP where it intersected 1.97 g/t Au over 8.0m, including 4.25 g/t Au over
2.6m. Within the southern sediments, four mineralized zones were intersected, the best being 1.25 g/t Au
over 7.8m and 1.44 g/t Au over 4.8m. The very predictable southern porphyry ("SPOR") marker unit
assayed 18.91 g/t Au over 0.6m. This narrow unit can be identified the full strike length of the Wenot
deposit, over 2km. The gold grade is highly variable, possibly related to coarse gold.
26ODD-192 (305380E) was collared on the north side of central Wenot and drilled to the south. This hole
tested the up-dip extension of multiple gold zones intersected in hole 172 in the Dike Corridor within the
volcanics, which returned 4.19 g/t Au over 6.0m, 4.48 g/t Au over 6.0m, and 2.18 g/t Au over 8.0m.
Similarly, hole 192 intersected several gold zones within the Dike Corridor, including 4.12 g/t Au over
10.7m (including 11.16 g/t Au over 3.7m), 2.71 g/t Au over 14.0m (including 17.08 g/t Au over 1.3m), 4.15
g/t Au over 5.6m (including 15.47 g/t Au over 1.4m), and 0.97 g/t Au over 35.0m. In aggregate, 67.6m
within the Dike Corridor are mineralized. Gold mineralized intervals in the sediments assayed 1.55 g/t Au
over 5.5m and 1.24g/t Au over 2.2m.
26ODD-193 (305230E) (see Figure 2. Cross Section) was drilled to the south and most notably intersected
an impressive 5.12 g/t Au over 40.5m at a vertical depth of between 260m to 290m, which includes a
high-grade zone of 11.29 g/t Au over 10.4m within wide, extensively-altered felsic dikes within the prolific
Dike Corridor. Approximately 125m below, hole 124W intersected 2.64 g/t Au over 41.8m within this same
horizon. This felsic unit is roughly 75m north of Wenot's central contact between the sedimentary and
volcanic sequences. Typical of the drill holes in the Central Wenot area, hole 193 intersected all of the
main lithologic units in sequence from north to south, including the volcanics, Dike Corridor, central contact
quartz feldspar porphyry ("CQFP"), protomylonite, sedimentary sequence and through to the southern
QFP ("SPOR"). A total of 11 gold zones were intersected. Two minor gold zones were intersected in the
volcanics, 1.82 g/t Au over 3.7m at a vertical depth of 90m and 4.66 g/t Au over 1.1m at a vertical depth of
136m.
Six separate gold zones were encountered within the Dike Corridor. The best zone, assaying 5.12 g/t Au
over 40.5m, as mentioned above. Additional zones from the Dike Corridor include 1.53 g/t Au over 4.9m,
1.10 g/t Au over 4.2m, 6.94 g/t Au over 1.4m, 3.17 g/t Au over 2.1m, and 6.45 g/t Au over 2.6m. The CQFP
assayed 1.48 g/t Au over 14.0m.
Within the southern sediments, a wide gold zone of 1.37 g/t Au over 26.0m was intersected.
26ODD-194 (304880E) intersected gold zones in all lithologies drilled. It was collared on the north side of
Wenot. It tested the up-dip extension of two very wide gold zones encountered in hole 23ODD-065 that
returned 4.54 g/t Au over 27.5m and 1.83 g/t Au over 25.5m in the Dike Corridor.
The Dike Corridor was intersected starting 77m downhole, consisting felsic and diorite dikes intruding the
volcanic sequence. Five gold zones were intersected in silicified felsic dikes with up to 1% disseminated
pyrite and multiple visible gold (VG) specks within quartz-ankerite veins. The best intercepts in the dike
corridor include 2.20 g/t Au over 14.7m (including 24.79 g/t Au over 0.9m) and 5.24 g/t Au over 7.9m.
Further downhole, at 308m, the Central contact complex was intersected consisting of the quartz feldspar
porphyry ("CQFP"), diorite, and protomylonite with quartz-ankerite veins, approximately 1% disseminated
pyrite, and one VG speck. Gold intercepts include 1.11 g/t Au over 17.9m and 1.27 g/t Au over 7.0m.
Within the southern sedimentary sequence, seven gold zones were intersected, the best being 6.54 g/t Au
over 3.0m including 12.68 g/t Au over 1.5m.
26ODD-196 (305630E) was collared in the sediments and drilled to the north, drilled to test the shallower
areas. An assay of 1.52 g/t Au over 3.0m was intersected in the saprolite, very far south of known Wenot
zones. Six zones were encountered within the sediments, the best being 2.46 g/t Au over 4.5m, including
6.92 g/t Au over 1.0m. A minor gold interval in a felsic dike north of the sediment-volcanic contact returned
1.29 g/t Au over 1.5m. The CQFP was intersected at 390m downhole (-260m vertically) but was not
mineralized. This section in the east central pit is unusual in that the CQFP did not run gold. A hole cutting
the CQFP about 35m below ran 1.68 g/t Au over 7.0m. This hole was not extended far past the central
contact since other holes had well tested the area to the north.
26ODD-198 (305330E) was drilled to the south almost 100m above hole 121 that returned several high-
grade intercepts in the dike corridor including 9.85 g/t Au over 2.9m, 13.74 g/t Au over 3.5m, and 11.26 g/t
Au over 2.0m. Hole 198 intersected eight impressive gold-mineralized intervals in the dike corridor with the
best include 5.32 g/t Au over 6.0m, 2.36 g/t Au over 16.4m (including 24.34 g/t Au over 1.0m), 1.64 g/t Au
over 10.0m and 4.43 g/t Au over 2.3m. The hole continued into the CQFP with mineralized quartz veins
that returned 1.01 g/t Au over 10.9m. Further downhole, five mineralized intervals were intersected in
diorite-intruded sediments with several occurrences of visible gold. The best intervals include 2.29 g/t Au
over 21.5m, 4.61 g/t Au over 9.4m (including 12.2 g/t Au over 1.3 m and 9.79 g/t Au over 1.4m), and 1.37
g/t Au over 5.2m.
WEST WENOT
26ODD-190 (304604E) was drilled above hole 020, which intersected high-grade intervals of 9.91 g/t Au
over 1.4m and 22.05 g/t Au over 1.7m within the dike corridor. Hole 190 similarly encountered high-grade
intervals of 3.15 g/t Au over 13.9m, including 22.95 g/t Au over 1.4m and 8.03 g/t Au over 2.6m
approximately 30m above hole 020. Two other mineralised intervals in the dike corridor assayed 1.60 g/t
over 6.5m and 1.29 g/t Au over 2.7m. The CQFP assayed 1.63 g/t Au over 8.3 m. Further south, nine (9)
additional gold zones were encountered within the southern sediments, including 2.0 g/t over 9.8m (which
included 7.83 g/t Au over 1.3m), 5.85 g/t Au over 1.0m, 2.73 g/t Au over 4.4m and 3.52 g/t Au over 3.3m.
26ODD-199 (304767E) was drilled south, targeting the upper extensions of several mineralized zones
encountered in hole 24ODD-077, including 2.46 g/t Au over 18.9m in the CQFP, and 1.01 g/t Au over
25.5m, 2.08 g/t Au over 10.8m, and 4.19 g/t Au over 4.8m in the sediments. Hole 199 intersected four gold
zones in the dike corridor, with a best interval of 3.78 g/t Au over 9.7m, including 7.75 g/t Au over 3.6m.
The CQFP hosted gold-mineralization, assaying 1.67 g/t Au over 10.6m. Four gold zones were
encountered in the sediments highlighted by 1.80 g/t Au over 15.0m, that includes 9.00 g/t Au over 1.4m.
At the southern edge of the Wenot shear corridor the very predictable, but typically narrow porphyry
returned 0.88 g/t Au over 6.1m.
EAST WENOT
26ODD-191 (305729E) was drilled to the south above hole 181 and as a scissor hole to 106 which was
drilled northward from the sediments. In hole 191, a total of nine mineralised zones were intersected in the
Dike Corridor including three separate high-grade intervals of 5.17 g/t Au over 7.4m (including 8.04 g/t
Au over 4.4m), 4.37 g/t Au over 7.5m (including 6.90 g/t Au over 3.0m), and 4.67 g/t Au over 2.3m in
silicified and sulphide-bearing zones with up to 15 occurrences of visible gold. The CQFP returned a
modest mineralized interval of 0.48 g/t Au over 5.3m.
26ODD-197W (305680E) was drilled to the south, wedged from hole 197 which deviated. Most noteable,
the Dike Corridor spanned 157m downhole (324m to 481m) with multiple gold zones that, in aggregate,
cover 46m within that interval. The best zones include 2.68 g/t Au over 40.7m, 2.72 g/t over 12.9m, and
2.16 g/t over 16.0m. The 40.7m interval contains 3 separate high-grade sub-intervals of 3.81 g/t over 15.7
m (including 7.20 g/t Au over 4.9m), 3.77 g/t Au over 5.7m and 5.38 g/t over 5.0m. This highly mineralised
section of the Dike Corridor is marked by abundant sulphides, quartz-ankerite veining within felsic dikes,
with multiple occurrences of visible gold. The CQFP hosts two minor zones of 0.39 g/t Au over 6.9m and
1.25 g/t Au over 2.7m. The adjacent protomylonite assayed 1.2 g/t Au over 1.1m. The best gold zones
within the southern sediments include 2.76 g/t Au over 2.4m and 0.87 g/t Au over 6.8m.
Geophysical Anomaly Tested
26ODD-189 was one of two holes drilled to test a geophysical anomaly (a magnetic high) that extends
northeast from the Wenot deposit, which itself is associated with a strong magnetic geophysical signature.
Hole 187 was previously reported. It encountered a sequence of andesitic volcanics with minor diorite
dikes. A minor gold zone in hole 187 within andesitic volcanics ran 0.50 g/t Au over 1.5m. A deformed
quartz vein with disseminated pyrite and patchy alteration that resembled parts of Wenot, appeared
interesting but assayed only 1.0 g/t Au over 3.0m. Hole 189 did not intersect any anomalous gold
mineralization. The magnetic susceptibility of the core identified a few high magnetic zones that may
correlate to the airborne signature. They do not appear to correlate to the gold zones intersected in hole
187.
