OMG NEWS RELEASE 1

Omai Gold Grants Incentive Stock Options

Toronto, Ontario – (March 10, 2025) – Omai Gold Mines Corp. (TSXV: OMG) (OTC: OMGGF)

(“Omai Gold” or the “ Company”) announces that it has granted incentive stock options to 12

individuals, including Officers, Directors, employees and consultants of the Company to purchase

up to 11,300,000 common shares of the Company pursuant to the Company's stock option plan.

The options have a five-year term at an exercise price of $0.33 per share, with one third vesting

upon the date of grant, one third on the first anniversary of the date of grant and the final third on

the second anniversary of the date of grant.

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 a Preliminary Economic Assessment (“PEA”)1 on its

Wenot Deposit at Omai in April 2024, showing an open pit operation to produce 1.84 million

ounces of gold over a 13 -year period, with an NPV 5% of US$556 million at a US$1 ,950/oz gold

price. This baseline PEA incorporates only 45% of the property’s MRE and management believes

that with additional work the mine plan can be significantly expanded, the economics enhanced,

and the open pit resources further increased. An updated NI 43-101 Mineral Resource Estimate

(“MRE”)1 of 2.0 milli on ounces of gold (Indicated) and 2.3 million ounces (Inferred) reflects a

notable increase as a result of 2023’s successful drilling. Once South America’s largest producing

gold mine, Omai produced over 3.7 million ounces of gold between 1993 and 2005 2. 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 road access and a wealth of historical data that provides

knowledge of the geology and gold mineralization on the Property, as well as metallurgy, historical

processing recoveries and many other relevant mining parameters.

1 NI43-101 Technical Report dated May 21, 2024 “UPDATED MINERAL RESOURCE ESTIMATE

AND PRELIMINARY ECONOMIC ASSESSMENT OF THE OMAI GOLD PROPERTY, POTARO

MINING DISTRICT NO.2, GUYANA” was prepared by Eugene Puritch, P.Eng., FEC, CET,

President of P&E Mining Consultants Inc. is available on SEDAR+ and on the Company’s website.

It includes a Wenot resource of 834,000 indicated ounces of gold averaging 1.48 g/t Au and

1,614,000 inferred ounces of gold averaging 1.99 g/t Au, and the adjacent Gilt Creek resource of

1,151,000 indicated ounces of gold averaging 3.22 g/t Au and 665,000 inferred ounces of gold

averaging 3.35 g/t Au.

2 Past production at the Omai Mine (1993-2005) is summarized in several Cambior Inc.

documents available on SEDARplus.ca, including March 31, 2006 AIF and news release August
