Why Oko West Trades Below NAV With First Gold 18 Months Away

G Mining Ventures is building one of the largest gold projects currently under construction anywhere in the world, and the market is pricing the company at a discount to what its assets are worth.

That tension sits at the heart of the Oko West story. With gold trading at elevated levels and genuinely large, low-cost projects advancing toward production in short supply, a development on this scale should command a premium. Instead, consensus values the company below its net asset value.

The commercial production timeline matters here. First gold is targeted for the second half of 2027, with commercial production expected in January 2028. That is close enough to reshape how investors think about entry points now, not a distant aspiration. What follows breaks down whether the discount is an opportunity or a reflection of risks the market has correctly priced, using the construction data, expansion logic, and capital structure that are actually on the table right now.

How far along is Oko West, and is the schedule holding?

Overall project progress reached 28% on an earned-value basis at the end of Q2 2026, according to management on the Q2 2026 earnings call held on 13 August 2026. That figure sat marginally below the company’s internal 30% target for the period.

The physical milestones tell a more encouraging story than the headline percentage alone.

• Detailed excavation of the carbon-in-pulp (CIP) area is complete
• Mass excavation for the primary crusher is complete
• Ball mill foundations have been poured
• Rebar and formwork preparation for the SAG mill piers is underway
• Tailings storage facility clearing reached 36% completion as of the Q1 2026 update

Detail engineering was expected to finish in Q3 2026, with procurement approximately 99% complete at the Q2 close. Both grinding mills were scheduled for delivery in July 2026, a sequencing that supports commissioning and operation by August 2027. Concrete works across the grinding circuit and main power plant engine hall stood at roughly 20% completion as of the Q1 2026 update, with volumes rising monthly.

Earned-value progression March 2026: 19.7% June 2026: 28%

That jump of more than eight percentage points in a single quarter shows the pace beginning to build. The two-point miss against the internal target is not itself alarming. What it signals is where the pressure sits: the steepest part of the construction ramp is still ahead.

The schedule math from here to first gold

The remaining window is tight. From Q3 2026 through the second half of 2027, roughly 12 to 15 months of peak activity separates the current position from first gold.

For context, the formal construction decision on 23 October 2025 cited 36% engineering complete at that point, which gives a baseline for measuring progress since. As of September 2026, the company continued to describe the project as on schedule and on budget.

Here is what that leaves you watching. Peak construction activity in late 2026 and early 2027 is where schedule risk concentrates, and the first gold timeline carries limited buffer. A slip to late 2027 or early 2028 would push back the cash flow inflection that the entire re-rating thesis rests on. For anyone evaluating G Mining Ventures now, the construction clock is the single most important variable on the board.

Why the Goose/G2 acquisition transforms the scale argument

Before April 2026, the Oko West investment case was straightforward: a Phase 1 operation producing approximately 350,000 ounces per year from January 2028, positioned favourably on the global cost curve, with a multi-year mine life. A strong project by any measure, but a defined one.

Then the ceiling moved.

On 9 April 2026, G Mining Ventures announced the acquisition of G2 Goldfields, combining Oko West with the adjacent Goose/G2 (Oko-Ghanie) deposits. The company describes the combined asset as “one of the largest lowest cost gold operations in the Americas” and “a tier-one gold mining hub in Guyana.”

The logic rests on geography and shared infrastructure. The integration creates a contiguous mineralised corridor, meaning the expansion can lean on the processing plant, power, tailings, and site infrastructure already being built for Oko West rather than duplicating them in a separate greenfield project. That capital efficiency is what supports the target of approximately 500,000 ounces per year with relatively modest incremental spending.

The April 2026 combination is designed to create what the company calls a tier-1 gold complex, where shared processing infrastructure across a contiguous mineralised corridor is the mechanism that converts two separately viable assets into a single operation with materially lower incremental capital requirements.

Permitting is a material part of the thesis, not a footnote. Oko West is fully permitted, and the acquisition release notes that combining with it is expected to accelerate Oko-Ghanie’s regulatory path relative to a standalone application.

That final row is the one to weigh carefully. As of September 2026, no formally published integrated feasibility study consolidates the combined economics into a single updated capex and cash flow case. The 500,000-ounce target is currently backed by strategic rationale and drilling results, not a completed technical study. When you assess the uplift, treat that distinction as central rather than incidental.

What the drilling and permitting pipeline actually shows

The company is advancing the expansion on drilling results and operational knowledge rather than a traditional staged feasibility process. Multiple drill rigs are active on infill programmes, with significant meterage targeted for resource definition, and updated studies incorporating those results are planned.

The regulatory framework has already demonstrated it functions. Guyana’s Environmental Protection Agency (EPA) processed the Oko West interim environmental permit in December 2024, authorising early works. Oko-Ghanie permitting, however, remains a gating factor without a firm end date.

The Guyana EPA environmental authorisation process requires a multi-stage submission, screening, and public consultation sequence before large-scale mining operations receive a full environmental permit, which explains why Oko-Ghanie’s regulatory path does not carry a firm closure date despite the precedent set by Oko West.

The working timeline runs like this: expansion pre-production expected in 2028, with expanded throughput targeted for 2029. Whether the shared-infrastructure model delivers on its capital-efficiency promise depends on drilling conversion and a permitting path that has not yet closed.

The capital structure behind a nearly US$1 billion build

The initial capital cost for Oko West is US$973 million, established at the construction decision on 23 October 2025. No subsequent company document has explicitly revised that figure, which makes it the anchor for any assessment of how the build is tracking.

US$973 million Initial capital cost, set at the 23 October 2025 construction decision and not formally revised as of September 2026.

The more useful question is how much of that exposure is already locked in versus how much still sits in front of the company. The commitment curve answers it.

1. September 2025: US$334 million committed, roughly 33% of the total
2. January 2026: approximately US$423 million committed, roughly 44% of the total
3. 2026 growth capex guidance: US$514-568 million, the largest single year of deployment

Pricing had been generally in line with expectations, per the January 2026 operational outlook. A revolving credit facility remains available, and the share buyback programme is active.

Read the commitment curve carefully and the risk window becomes obvious. With approximately 44% committed by January 2026, more than half the US$973 million total still lay ahead at the start of the peak construction year. That is precisely where cost overrun risk concentrates in large mining builds: the back half of the spend, deployed during the busiest construction phase.

The company’s capital allocation philosophy shapes how any surplus gets used. Organic exploration is preferred where discovery costs beat acquisition costs per ounce, selective M&A is deployed for strategic near-term ownership, and share buybacks are used when shares trade below net asset value.

Large-scale gold project financing at the US$500 million level increasingly involves hybrid structures that blend senior debt, stream components, and equity to manage the concentration risk that comes with single-project development companies during their most capital-intensive construction phase, a dynamic directly relevant to how investors should read G Mining Ventures’ commitment curve through 2026.

For you as an investor, the US$514-568 million guidance band is the clearest near-term signal available. How closely the actual outturn tracks that range will tell you whether the US$973 million budget is holding or slipping, well before first gold arrives to settle the question definitively.

Is the P/NAV discount an opportunity or a fair reflection of the risks?

Consensus price-to-net-asset-value (P/NAV) for G Mining Ventures sits at approximately 0.86x, below the company’s peer group, according to Crux Investor commentary from October 2025. P/NAV measures the market price against the estimated worth of the company’s assets, so a figure under 1.0x means the market is valuing the company at less than analysts calculate its projects are worth. With a market capitalisation of approximately CAD 15 billion as of late September 2026, the size of that discount is not trivial.

Two interpretations compete for the reading, and both deserve genuine weight.

The company’s own framing “One of the largest lowest cost gold operations in the Americas” and “a tier-one gold mining hub in Guyana.”

The opportunity case leans on that characterisation and on management’s history of delivery. The risk case points to the jurisdiction, where interior mining areas lack the mature grid, road, and port infrastructure of established hubs, forcing the project to self-fund power, logistics, and tailings capacity. The portfolio context adds texture: Tocantinzinho (TZ/TZI) is already producing and contributing value, while Gurupi carries a lower assigned valuation pending advancement.

District-scale buyout activity on the Oko shear provides a market-derived reference point for valuing contiguous mineralised ground; the A$4 billion in acquisitions already completed on the same geological trend suggests that third-party buyers have formed a view on the district’s value that is not fully captured in G Mining Ventures’ current 0.86x P/NAV.

Here is where the earlier sections sharpen the read. The construction data shows execution holding but the steepest ramp still ahead. The expansion data shows a compelling scale story that lacks a completed technical study. Neither thesis is wrong; they are describing different stages of the same clock.

The most telling signal comes from the company itself. The active share buyback is management’s own statement that it believes 0.86x understates intrinsic value. You have to decide whether you share that conviction before the construction milestones that would settle the debate arrive in 2027.

Because the valuation question will not resolve in a spreadsheet. It will resolve in the Q3 and Q4 2026 construction updates, and then definitively when first gold is poured. Positioning ahead of those catalysts is a bet on execution, not simply on the gold price.

What needs to happen for Oko West to deliver on its scale promise

Strip the story back to what remains genuinely open, and three variables will decide whether the scale promise is met.

1. Construction execution through peak activity in late 2026 and early 2027. This is the window where schedule risk concentrates and where the first gold timeline has the least buffer.
2. The integrated feasibility study. A formal study consolidating the combined economics is what would convert the 500,000-ounce target from strategic rationale into a validated technical case.
3. Guyana’s permitting timeline for Oko-Ghanie. The expansion cannot advance without it, and it currently lacks a firm end date.

The shared-infrastructure platform is the thread that ties all three together. If it works, the capital-efficiency argument is validated and the expansion economics fall into place. If any leg fails, whether a construction slip, a disappointing study, or a permitting delay, the upside case narrows materially.

The company’s stated sequence puts development first, followed by shareholder returns and selective growth. Strong free cash flow generation is expected once the full production profile is achieved, drawing on the April 2025 feasibility study economics, though no formal revision to those figures has been published as of September 2026.

That points to the milestone that matters most. January 2028 commercial production is not merely a calendar date; it is the moment free cash flow moves from projection to actuality. How closely the initial production profile tracks the feasibility study numbers will set the terms of the re-rating conversation for years afterward.

For anyone tracking this now, the next twelve months of construction updates form the most information-dense period in Oko West’s development history. The gap between today’s discount and a potential re-rating to peer multiples will narrow or widen based on what those updates show.
