Omai Gold Mines: Heavy Drilling and a $6.2 Billion PEA Build a Majors-Scale Case in Guyana

Omai Gold Mines is halfway through a 50,000-meter drill program at its 100%-owned Omai project in Guyana, and the September 1 Lab Report on CEO.CA argues that fresh high-grade intersections plus a newly announced economic study are building the profile major gold producers look for: meaningful production, a long mine life, and room to keep growing.

The host's central point is scale. The recently announced preliminary economic assessment (PEA — an early-stage study of whether a deposit can be mined at a profit) points to a mine producing 250,000 to 300,000 ounces of gold per year, and he highlights a plan averaging 350,000 ounces per year over an 18-year mine life. In his framing, that sits squarely in the range majors want — 250,000 to 500,000 ounces per year with a long life — and assets offering that combination are scarce.

## What the drills are returning

The company just reported results from 11 holes, with five drill rigs active and 74 holes totaling 35,000 meters completed of the 50,000-meter program. The headline hole, 193, cut 11 discrete gold zones, including 5.12 grams per tonne of gold (g/t — grams of gold per tonne of rock) over 40.5 meters. Inside that interval sat 11 g/t over 10.4 meters, at a vertical depth between 260 and 290 meters. With gold trading above $100 per gram, the host values that 5.12 g/t rock at roughly $600 per tonne — his arithmetic, offered as a way to size the grade.

Hole 192 added 11 g/t over 3.7 meters and 2.7 g/t over 14 meters, and the host describes the release as strong results "hole after hole after hole." President and CEO Elaine Ellingham is quoted welcoming the continued strong drill results, and drilling runs through mid-December 2026 — which the host reads as a steady flow of news well into 2027.

The program also reaches downward. A hole testing the deposit's depth potential was completed at a vertical depth of 1,200 meters, and the host argues the high-grade zone between 260 and 290 meters would be attractive ground for a future underground operation — a second way to mine the deposit alongside the open pit under study.

## Reading the grades

The deposit is being evaluated at a cut-off grade of 0.3 g/t for open-pit mining. A cut-off grade is the line between ore and waste: rock above it is expected to pay for its own mining and processing, rock below it does not. A low line like 0.3 g/t matters because a broad band of material between that threshold and the high-grade cores still counts as ore, and deposits that clear a low bar profitably tend to be forgiving ones to mine.

## Why the PEA matters

Drilling has already lifted the resource estimate by 86%, the host notes, and he ties that growth to the larger mine plan and a lower anticipated strip ratio — the tonnage of waste rock moved for each tonne of ore. Lower means less digging of barren rock before the gold-bearing material arrives. At a $4,500 per ounce gold price, he says the PEA supports a net present value (NPV — the project's expected future cash flows translated into today's dollars using a discount rate) of $6.2 billion at 5%.

## The valuation argument

That $6.2 billion figure is set against a market value of about C$1.7 billion — roughly 0.3 times the NPV the host cites. He argues the gap is reasonable given how rare it is to find a multi-million-ounce deposit with an 18-year mine life at the PEA stage producing around 350,000 ounces per year, calls it the kind of project major mining companies would want to own, and places the company about three-quarters of the way up the left side of the Lassonde curve — an industry chart that tracks how a developer's valuation tends to build from discovery toward production. In a takeover scenario, he says it is "quite easy to imagine" a $2.5 billion to $3 billion valuation, and that an offer for Omai "would not surprise" him at any time. Those are his projections, not company guidance.

## What to watch

The near-term catalyst is drilling: five rigs running to mid-December, with results expected into 2027 and further work building on the PEA. The caveats matter. A PEA is preliminary by definition, and its economics can move with metal prices, engineering choices, and additional drilling.
