OMAI INCREASES INDICATED MINERAL RESOURCES TO 2.1 MOZ AU (2.07 g/t Au, 31.9Mt) AND INFERRED MINERAL RESOURCES TO 4.4 MOZ AU (1.95 g/t Au, 69.6Mt) WITH EXPANSION OF WENOT DEPOSIT
August 25, 2025, Toronto, Ontario – Omai Gold Mines Corp. (TSX.V: OMG) (OTCQB: OMGGF) (“Omai Gold” or the “Company”) is pleased to report an updated Mineral Resource Estimate (“MRE”) on its 100%-owned Omai Gold Property in Guyana.
The MRE includes an expansion to the Wenot Deposit and incorporates the previously disclosed Gilt Creek Deposit.
Most significantly, for the Wenot Mineral Resource Estimate (“MRE”), the Inferred MRE increased 130% to 3,717,000 oz grading 1.82 g/t Au, contained in 63.4 million tonnes (“Mt”), and the Indicated MRE increased 16% to 970,000 oz grading 1.46 g/t Au, contained in 20.7 Mt.
.
HIGHLIGHTS:
The Omai Property hosts two orogenic gold deposits: the shear-hosted Wenot Deposit and the adjacent intrusive-hosted Gilt Creek Deposit (Figure 1), with a combined updated MRE (over the February 2024 MRE) of:
• 2,121,000 ounces of gold (Indicated MRE), a 7% increase, averaging 2.07 g/t Au in 31.9Mt &
• 4,382,000 ounces of gold (Inferred MRE), a 92% increase, averaging 1.95 g/t Au in 69.6Mt
Wenot Deposit (a constrained pit and underground approach is applied)
• 970,000 oz of gold in 20.7Mt (Indicated), a 16% increase in ounces over the Feb 2024 MRE
• 3,717,000 oz of gold in 63.4Mt (Inferred), a 130% increase in ounces
• 1.46 g/t Au grade of Indicated MRE, a 1.4% decrease*
• 1.82 g/t Au grade of Inferred MRE, an 8.5% decrease*
• *Increased gold price assumption to $2,500/oz from $1,850/oz allowed cutoff lower to 0.30 g/t Au
from 0.35 g/t Au, resulting in lower average grades however increased ounces
• ~60% above 350m depth from surface (Figure 2a)
• ~30% of Wenot MRE is west of the historical open pit, an area considered to be well suited to initial mining.
• Expansion potential is evident along a minimum 2.5 km length of the host Wenot shear corridor, including within, adjacent to, below, and along strike Gilt Creek Deposit (an underground mining approach is applied)
• 1,151,000 ounces of gold (Indicated) averaging 3.22 g/t Au, in 11.1Mt (Feb 2024 MRE)
• 665,000 ounces of gold (Inferred) averaging 3.35 g/t Au, in 6.2Mt (Feb 2024 MRE)
• Hosted within a 500m by 300m quartz diorite intrusive “Omai stock” that produced 2.4 million ounces of gold (1993 to 2005) from the upper 250m
• Located 500m north of the Wenot Deposit and below the past-producing Fennel open pit
• Characterized by very wide sub-horizontal zones of gold mineralization (Figure 5)
• Open to depth and holds demonstrated potential for lateral expansion.

Elaine Ellingham, President & CEO commented,
“We are pleased to be delivering yet another very substantial increase to the Mineral Resource Estimate for our Omai Gold Project in Guyana.
“This firmly positions Omai as one of the top two largest gold projects in Guyana. Omai has many benefits as a brownfields project, not the least of which is road access (mostly paved), an airstrip, a cleared site, established tailings sites and known past production parameters.
“In addition to these clear advantages, Guyana has proven to be a favourable jurisdiction, now recognized by the Fraser Institute as the 9th best jurisdiction for mining investment in the world, with a Government and people that are supportive of large-scale mine development.
“This updated Mineral Resource Estimate reinforces the potential for accelerated large-scale mine re-development at Omai, a project that continues to deliver superior value
creation for all stakeholders.
“With each successive milestone it becomes clearer that Omai has the potential to be a multi-decade world-class gold mining operation.
“Notwithstanding this large gold Mineral Resource Estimate we announced today, we still see very significant potential to further expand the gold zones at both the Wenot and the Gilt Creek Deposits.
“We will continue to aggressively drill to increase these Mineral Resources and to upgrade the Inferred Mineral Resource Estimate, in order to advance the project towards a Feasibility Study later in 2026.
“Two drills are currently turning on nearby known gold occurrences, exploring for near-surface satellite deposits, while the third drill continues on a deep hole (25ODD-122) that drilled across the Gilt Creek Deposit and continues, with the goal of testing the blue sky depth potential of the adjacent Wenot Deposit.”
