OMG NEWS RELEASE 1

Omai Gold Acquires Eastern Flats Mining

Permits Adjoining Omai Property

December 22, 2021 Toronto, Ontario — Omai Gold Mines Corp. (TSXV: OMG) ("Omai"

or the "Company") is pleased to report the closing of the acquisition of the Eastern

Flats property, a 1,519 acre property consisting of prospecting and mining rights,

located immediately east and contiguous to Omai’s 4 ,590 acre prospecting licence,

which includes the past producing Omai Mine. The a cquisition of a 100% interest in

the Eastern Flats prospecting and mining rights is completed upon payment of a

residual US$1, with no royalty or further obligations.

The Company entered into an exclusivity agreement ( the “Exclusivity Agreement”)

dated July 13, 2020, and a subsequent prospecting a nd licence management

agreement (“Prospecting and Licence Management Agreement”) dated April 16, 2021

between Omai Gold Mines Corp. and a non-arm’s length party, Guyana Sunrise Mining

Inc. (together, the “Agreements”). Pursuant to the terms of these Agreements, the

Company (i) in July 2020, issued 6,000,000 common shares to the Vendor at the time

of signing of the Exclusivity Agreement, and (ii) will pay USD$1 in cash to the Vendor.

The transaction was subject to TSX Venture Exchange approval, which has been

granted.

The Eastern Flats property is strategically located along strike of the Wenot shear

corridor that extends 1.7 km along the axis of the past producing Wenot pit. The

Wenot pit produced over 1.4 million ounces of gold at an average grade of 1.5 g/t

before ceasing operations in 20031.

Recent airborne geophysics over the Eastern Flats l icences, consisting of magnetics

and radiometrics, highlighted several prospective t argets bearing geophysical

signatures which are similar in nature to those ass ociated with gold deposits on the

adjoining Omai property. Additionally, many of thes e geophysical targets are co-

incident with anomalous gold values in auger soil s amples that were collected at

(shallow) depths of <1 meter, along thirteen N-S lines spaced 400 m apart. While these

results reveal several impressive and sometimes bro ad gold-in-soil geochemical

anomalies no further work was carried out on the Eastern Flats.

OMG NEWS RELEASE 2

Omai’s chief geologist, John Spurney stated "the broad gold-in-soil geochemical

anomalies at Eastern Flats, impressive as they are, saw little follow up investigations

during the 1990's mine era, even though at greater than 100 ppb gold and in some

instances up to 500 ppb. Some of these areas appear large enough to conceal another

deposit the size of Fennell or Wenot. Our technical team is currently compiling data

and developing a plan to evaluate Eastern Flats as part of our 2022 exploration

program.”

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, that

includes the past producing Omai gold mine. Once So uth America’s largest

producing gold mine, Omai produced over 3.7 million ounces of gold between 1993

and 2005. Mining ceased at a time when the average gold price was less than US$350

per ounce, leaving significant drilled resources untapped. The Company’s short-term

priorities are to verify and expand the known resou rces, while advancing exploration

on nearby targets, providing a solid opportunity to create significant value for all

stakeholders.
