Omai Gold Mines has pushed its Guyana project into sharper focus after raising total contained resources by 22% to 8 million ounces. The April 14 update matters because it moves the company closer to the scale that often attracts larger producers in gold M&A.
The market responded quickly. Omai shares rose 10% after the announcement. At the same time, investors began to focus on what the larger resource could mean for the next economic study and for strategic interest in Guyana.
As gold prices stay firm, Omai’s scale and production history are drawing attention from operators looking for long-life assets in stable mining jurisdictions.
Resource Update Lifts Omai to 8 Million Ounces
The updated estimate follows an 18,000-meter drill program completed over the past year. The new figures increase both total ounces and confidence in parts of the deposit.
The project now hosts 38.1 million indicated tonnes grading 2.04 grams of gold per tonne (g/t), containing about 2.5 million ounces. It also hosts 106.6 million inferred tonnes grading 1.59 g/t, containing about 5.5 million ounces.
A key part of the update was the conversion of higher-grade inferred material into the indicated category. That matters because it lowers development risk and gives the next round of economic work a stronger base. The 22% increase came mainly from the Wenot and Gilt Creek deposits.
Wenot Remains the Open-Pit Anchor
The Wenot deposit remains the main driver of Omai’s open-pit case. After the latest drilling, indicated resources at Wenot rose to 1.45 million ounces at 1.59 g/t, up from 969,000 ounces.
Inferred resources at Wenot also increased to about 3.9 million ounces. That near-surface inventory matters because it could support early years of production and cash flow. Omai is also looking to improve mine design by using modern open-pit mining technologies.
Gilt Creek Adds Underground Scale
While Wenot provides open-pit scale, Gilt Creek adds higher-grade underground potential. Total resources at the Gilt Creek underground deposit expanded to about 2.5 million ounces grading 3.26 g/t.
That increase followed geological reinterpretation and targeted deep drilling. As a result, Omai lifted tonnage while keeping a strong average grade. This is important because the company’s broader plan depends on combining open-pit and underground mining into one long-life operation.
Next Catalyst Is the Updated PEA
The next key milestone is the Preliminary Economic Assessment, which is expected within the next two to three months. The market is watching closely because the larger resource could support a much bigger operation than earlier plans suggested.
In 2024, the PEA focused on an open-pit-only mine producing about 142,000 ounces a year. The 2026 resource update changes that picture. Analysts now estimate production could reach 250,000 to 300,000 ounces per year. If that holds, Omai would rank among the larger gold projects in South America.
The company is also still drilling. A 50,000-meter program is underway to expand the resource and upgrade part of the 5.5 million ounces now classified as inferred. That work matters because it could strengthen a future feasibility study.
Market Reaction Fuels Takeover Talk
Investor reaction was swift. After the announcement, Omai Gold shares rose 10% to a record C$2.34 on the Toronto Stock Exchange. That lifted the company’s market value to about C$1.58 billion, or $1.14 billion.
However, the move reflects more than the new resource total. It also reflects rising speculation that a larger producer could take interest. Large gold projects with this kind of scale are hard to find, especially in jurisdictions seen as supportive of mining.
Omai’s 8 million-ounce inventory adds to that appeal. So does its existing infrastructure, including road access and power, and its operating history. The original Omai mine produced 3.7 million ounces between 1993 and 2005. Because of that legacy, the project is often viewed as more advanced than a typical greenfield asset.
On common mining investment valuation metrics, Omai’s value per ounce in the ground still appears competitive against peers, even after the rally. Guyana also adds a jurisdictional advantage because it has attracted more international capital in recent years.
Guyana’s Broader Mining Push Supports the Story
Guyana is no longer a fringe mining market. The government has set a 2026 gold declaration target of 510,450 ounces, and projects such as Omai are central to that ambition.
The country is also seeing more capital flow into mining. Oko West is expected to begin production in 2027, while Aurora continues to post strong output. That growing pipeline supports the case for Guyana as a more important regional gold hub.
However, faster growth also brings pressure. Competition for skilled labor is rising, including for mining engineers and technical staff. At the same time, the government is formalizing the sector and expanding oversight. That matters because major producers and institutional investors generally want clearer rules and permitting visibility.
What Comes Next for Omai Gold
Omai Gold has moved further from pure exploration and closer to a development decision. The 22% increase to 8 million ounces gives the project more scale and a stronger case for major capital investment.
As the company heads toward its updated PEA, the main question is whether a combined Wenot-Gilt Creek plan can deliver the size and economics the market now expects. However, the answer will depend on mine design, capital needs, and how much inferred material can be upgraded.
For now, Omai stands out as one of the larger undeveloped gold stories in the Guiana Shield. Because of that, it is likely to stay on the radar of operators, investors, and policymakers watching Guyana’s mining expansion.
