Omai Gold Announces Changes to the Board of Directors

April 4 2023, Toronto, Ontario — Omai Gold Mines Corp. (TSXV: OMG) (OTC: OMGGF) (“Omai

Gold” or the “Company”) announces the following changes to the Board of Directors:

- Renaud Adams is stepping down from his position as Chairman and director as a result

of his increased responsibilities associated with his recent appointment as CEO of Iamgold

Corp. Mr. Adams has offered to join Omai’s Advisory Board;

- Don Dudek, a director of Omai Gold since June 2022, has been appointed as the

Chairman, effective immediately.

The Company wishes to thank Mr. Adams for his contributions since the Company went public in

late 2020. Renaud commented: “It has been a pleasure serving on the Omai Gold Board and it

has been an exciting couple of years as we quickly established a significant gold resource at this

past-producing mine property in Guyana. I look forward to continuing to contribute through Omai’s

Advisory Board as I see a path for Omai to again become a significant gold producer.”

Mr. Dudek joined as a Director of Omai Gold in June 2022. Don is a geologist with over 40 years

of experience in senior technical and corporate roles with junior to senior exploration and mining

companies. He recently served as President and CEO of Savary Gold Corp., which was sold to

Semafo Inc. in 2019. He has held senior technical roles for a number of mining companies

including Endeavour Mining Corporation, Avion Gold Corporation and Aur Resources, and is

currently Vice President Exploration for Wolfden Resources Corporation and Technical Director

for Desert Gold Ventures. Don brings considerable board experience with publicly traded

companies. He holds a B.Sc. Geology (Honours) from the University of Saskatchewan.

“We are pleased to welcome Don Dudek as the new Chairman of Omai Gold . He brings a

tremendous amount of experience over a long and successful career which will be valuable as

we advance the Omai project. His hands-on experience with West African gold deposits is

particularly salient for our work in the Guiana Shield. On behalf of the Board of Directors I would

like to thank Renaud Adams for the role he played in the building of our substantial resource base

and look forward to having him as a member of our Advisory Board.” said Elaine Ellingham, CEO.

Don Dudek, Omai Gold’s newly appointed Chairman commented: “Omai’s gold project in Guyana

is an intriguing story. Not only has it produced 3.7 million ounces of gold, which rates it as a

significant-sized gold deposit but Omai Gold has added almost as much in new mineral resources.

After visiting the site last year , reviewing the detailed exploration data and comparing these

deposits to similar -age deposits in West Africa, I am convinced that the Wenot and Gilt Creek

gold zones are predictable and robust and I believe that Omai will be able to further increase the

size of these deposits. I look forward to my new role as Chairman and working more with the team

as we develop this asset.”

ABOUT OMAI GOLD

Omai Gold Mines Corp. holds a 100% interest in the Omai Prospecting License that includes the

past producing Omai gold mine in Guyana, and a 100% interest in the adjoining Eastern Flats

Mining Permits. The Company announced an updated Mineral Resource Estimate that includes

the Wenot shear-hosted gold deposit and the adjacent Gilt Creek intrusion- hosted deposit. The

recent NI 43-101 Mineral Resource Estimate includes: 1,907,600 ounces of gold (Indicated) at an

average grade of 2.07 g/t gold and 1,777,600 ounces of gold (Inferred) at an average grade of

2.10 g/t gold. Once South 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$400 per ounce. As a brownfields project, Omai benefits from good access and

a wealth of historical data that provides knowledge of the geology, nature of the gold

mineralization on the property, as well as metallurgy and historical recoveries. The Company’s

priorities for 2023 are to drill the key exploration targets that hold potential for significant new

discoveries while continuing to expand the Wenot deposit.
