Omai Gold Mines Corp.
Omai Gold Mines holds 100% of the historic, past-producing Omai gold mine site in Guyana's Guiana Greenstone Belt, which produced 3.8 million ounces between 1993 and 2005, comprising the shear-hosted Wenot deposit and the adjacent intrusion-hosted Gilt (Gilt Creek) deposit. An April 2026 resource update lifted the combined estimate to 2.5 million ounces Indicated at 2.04 g/t (38.1 Mt) plus 5.465 million ounces Inferred at 1.59 g/t (106.6 Mt) -- an 8-million-ounce system, of which Wenot holds 1.45Moz Indicated and 4.0Moz Inferred and Gilt holds 1.04Moz Indicated and 1.47Moz Inferred. A maiden Preliminary Economic Assessment covering the Wenot open pit and the Gilt underground deposit together was published on 19 August 2026: after-tax NPV5% of US$4.0 billion at a US$3,600/oz base case (US$5.5 billion and a 30% IRR at US$4,200/oz), a 24% IRR, 4.1-year payback and an 18-year mine life producing 6.33Moz of payable gold (351,488 oz/year average, peaking at 435,667 oz) for US$1.426 billion of initial capex at US$1,608/oz AISC.
Notable vs. Peers
- Jurisdiction risk score of 6/10 is meaningfully riskier than the peer average of 7.8/10.
Lifecycle Milestones
Not in place: mill. Not yet determined: grid power.
Jurisdiction (40%)6/10
Guyana is currently one of South America's most stable, fastest-growing economies, but its hard-rock mining regulatory framework and infrastructure are less mature than Tier-1 jurisdictions.
Infrastructure (40%)5.7/10
No confirmed mill, confirmed road access, and a confirmed tailings facility at Omai Gold Project (Wenot and Gilt Creek), Potaro Mining District, Guyana; grid power not yet researched, counted at a neutral 5/10 until established.
Nearby producing mine (20%)Not yet researched
No producing mine within 50 km in our reference list (nearest listed: Rosebel (Zijin Mining Group), 400 km). That list doesn't cover every mining district yet, so a longer distance isn't scored as remote.
Acquisition Susceptibility
A relative ranking of how closely this company matches the profile of juniors that have actually been acquired — not a probability, and not a reason to buy. Acquisitions are rare: only a few dozen significant deals happen a year across a universe of thousands of juniors, so even a high score here describes a long shot. The strongest signal in the research, a producer that already owns part of the company, is scored from its disclosed strategic shareholders. A producer that is a joint-venture or earn-in partner on the project, rather than a shareholder, isn't captured yet.
How this score is built
- Disclosed pending dealSub-score: Not scored
No pending acquisition or merger disclosed (checked)
Not scored: having no deal in flight isn't held against a company.
Weight 26.25% - Producer's strategic stakeSub-score: Not scored
No producer holds a disclosed stake on file (holder register researched) See holders
Not scored: most juniors that do get bought had no prior toehold, so a missing stake says little either way.

Insiders, Investors & Smart Money
Notable shareholders and insiders whose involvement is worth knowing about, plus what we're seeing from institutional/large-investor activity.
The Franklin Gold & Precious Metals Fund holds 3.2%, and unusually for this dataset that figure is current -- it is dated 10 August 2026, five days before this assessment. It is a genuine actively managed precious-metals fund rather than an index vehicle, though the position is below the size that would signal real conviction. Director David Stewart bought 50,000 shares on the open market in February 2025 and no insider has ever sold. Institutional ownership is 27.5%.
