Omai Gold Announces Final Wenot 2021 Drill Results Including

15.2 g/t Au over 6.0 metres and 2.3 g/t over 10.5 m and Drilling

Commenced at Broccoli Hill

December 8, 2021 Toronto, Ontario — Omai Gold Mines Corp. (TSX V: OMG) (“Omai” or the

“Company”) is pleased to report that the 2021 drilling program has been completed on the Wenot

gold deposit at its Omai project in Guyana. Drilling commenced in late November on the Broccoli

Hill target area. Results for the final three diamond drill holes at Wenot are reported, with highlights

including1:

• 15.2 grams per tonne gold (“g/t Au”) over 6.0 metres (“m”), 1.38 g/t over 16.5 m and 1.8

g/t over 13.5 m in hole 21ODD-024 (Section 305730E)

• 2.3 g/t Au over 10.5 m in hole 21ODD-025 (Section 305300E)

• 2.12 g/t Au over 10.5 m and 1.15 g/t over 19.5 m in hole 21ODD-026 (Section 305840E)

1A list of mineralized intervals in holes 21ODD-024, 025 and 026 appear in Table 1. Hole locations are

provided on Table 2 and are shown in figure 1.

At Wenot, a program of 16 diamond drill holes (8,181 m) was completed in 2021. E very hole

intersected the wide deformation corridor that hosts multiple, near-vertical, gold mineralized

shears. A longitudinal section (figure 2) shows the drill holes testing along the strike length of the

mineralization beneath the past producing pit. This drilling confirms that the mineralized zones

continue to depths of at least 150 to 225 m beneath the past producing pit and extend along the

full 1.7 km strike. The Wenot pit produced 1.4 million ounces 2 of gold at an average grade of 1.5

g/t Au between 1994 and 2003.

A comprehensive list of the 2021 Wenot drill results is provided on our website

www.omaigoldmines.com/press-releases/. The best intersections from the 2021 program

reported to date include:

- 21ODD-001: 9.0 g/t Au over 16.0 m and 3.6 g/t over 13.5 m

- 21ODD-002: 3.6 g/t Au over 32.1 m

- 21ODD-008: 6.6 g/t Au over 9.0 m

- 21ODD-009: 36.2 g/t Au over 2.0 m

- 21ODD-013: 6.92 g/t Au over 19.0 m

- 21ODD-021: 5.16 g/t Au over 8.4 m

- 21ODD-022: 16.77 g/t Au over 6.0 m and 4.63 g/t Au over 20.0 m

- 21ODD-023: 3.30 g/t Au over 14.1 m

- 21ODD-024: 15.20 g/t Au over 6.0 m

OMG NEW S RELEASE 2

An independent Qualified Person (“QP”) with P&E Consulting completed a site visit during the

first week of November and is advancing towards a NI 43-101 mineral resource estimate for the

Wenot deposit, which is expected to be completed before year end.

Elaine Ellingham, CEO, commented “Completing the drilling of the Wenot deposit along a 1.7 km

strike length and to depths of 150 to 225 metres below the pit is a great achievement for this year.

The continuity of the deformation zone that hosts the deposit has proven to extend to depth with

mineralization at similar grades and widths as was seen in the upper parts of the deposit, and

these zones remain open with further depth potential . Every drill hole completed at Wenot

intersected multiple gold mineralized zones . We look forward to delivering our first NI 43-101

resource before year end.”

“We commenced field exploration in late September on one of our next priority targets, Broccoli

Hill. I t has been an area of small scale and artisanal mining operations within the saprolite for

over a hundred years, but surprisingly has seen relatively little modern exploration or drilling. Our

trenching and mapping has already uncovered clusters or packets of quartz veinlets , similar to

those that often host gold mineralization at Omai. A limited initial drill program commenced a few

weeks ago to test some of these exposed quartz veinlet systems , areas identified by our

trenching, and the historic gold anomalies defined by soil and auger sampling. The drilling will

also provide a better understanding of the bedrock geology of this sizeable target area. Its

proximity to the Fennell deposit just 200 metres to the west, that produced 2.4 million ounces of

gold2, together with similarities in the geophysic al signature, has suggested the potential for

another Fennell-type deposit. We look forward to results from our initial drilling in the next week

or two.”

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. Standards, blanks and duplicates are

entered at regular intervals. Samples are sealed in plastic bags and shipped to ActLabs, a certified

laboratory 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. 30 g of pulverized material are then fire assayed

by atomic absorption (AA). Initial assays with results above 3,000 ppb gold are re-assayed with

gravimetric finish. Standards and blanks meet with QA/QC specifications.

About Omai Gold Mines Corp.

Omai Gold Mines Corp., through its wholly owned subsidiary Avalon Gold Exploration Inc., holds

a 100% interest in the Omai Prospecting License covering 4,590 acres (18.575 sq. km) , that

includes the past producing Omai gold mine. Once South America’s largest producing gold mine,

Omai produced over 3.8 million ounces of gold between 1993 and 2005. Mining ceased at a time

when the average gold price was less than US$400 per ounce, leaving significant drilled

resources untapped and prime exploration targets untested. The Company’s short-term priorities

are to verify and expand the known resources, while advancing exploration on key targets,

providing a solid opportunity to create significant value for all stakeholders.
