Why GMIN’s Oko-Ghanie Figures Aren’t Certified Resources Yet

On 29 July 2026, GMIN closed its acquisition of the Oko-Ghanie Project in Guyana and, in the same press release, included a disclosure that many investors may have read past. The mineral resource figures circulating since the 9 April 2026 joint announcement are not current mineral resources under NI 43-101. They are historical estimates, and GMIN’s Qualified Person has not done sufficient work to classify them as current.

That distinction matters. The Oko-Ghanie figures had already entered investor discussions as a proxy for the project’s resource base following the April announcement. Investors who absorbed those numbers as certified now need to understand what historical classification actually means, why GMIN made this disclosure, and what must happen before those figures carry the regulatory standing that investment decisions require.

This piece explains the regulatory difference between historical and current mineral resource estimates under National Instrument 43-101 (NI 43-101), maps the specific technical workstreams GMIN must complete before reclassification, and lays out the three-step disclosure pathway the company has committed to, including a 2027 technical report targeting mine plan optimisation.

What GMIN’s closing announcement actually said about the Oko-Ghanie resource figures

The Oko-Ghanie resource figures entered public circulation through a two-event sequence:

• 9 April 2026: Joint announcement of the arrangement between GMIN and G2 Goldfields; Oko-Ghanie mineral resource figures publicised alongside the gold opportunity in Guyana.
• 29 July 2026: Closing of the arrangement announced; GMIN clarified the regulatory standing of those resource figures as historical estimates, not current mineral resources under NI 43-101.

The April headlines carried the numbers. The July closing carried the regulatory context those numbers require.

GMIN’s Qualified Person “has not done sufficient work to classify the historical mineral resources estimates of the Oko-Ghanie Project referenced therein as ‘current’ mineral resources” and “is not treating such historical estimates as current mineral resources.”

GMIN is not disputing the project’s geological context or casting doubt on the quality of G2 Goldfields’ prior technical work. It is stating a specific regulatory position: under NI 43-101, the figures are historical estimates that require verification before they can be treated as current. Investors who read the April announcement and treated those numbers as a certified resource base are operating on an incorrect premise.

The NI 43-101 difference between “historical” and “current” mineral resources

Under Canada’s NI 43-101, a current mineral resource estimate must be prepared or verified by a Qualified Person (QP) in accordance with the standard before it can be formally relied upon by investors. The QP’s role is to independently assess the data, methods, and assumptions underpinning the estimate and to certify that the figures meet the threshold for investor reliance.

A historical estimate, by contrast, predates the current company’s own QP validation. The issuer is required to disclose it explicitly as historical and to caution investors against treating it as a current resource or reserve.

The framework exists because mineral resource figures drive investment decisions. NI 43-101 is designed to ensure that the figures investors rely upon have been independently validated by a qualified professional acting under the acquiring company’s own disclosure obligations.

The CIM Definition Standards underpin the resource classification categories referenced throughout NI 43-101, establishing the precise criteria a Qualified Person must apply when assigning Inferred, Indicated, or Measured classification to a mineral resource estimate.

Why G2’s prior technical work does not automatically transfer to GMIN

The change in corporate ownership is the trigger. G2 Goldfields completed a Preliminary Economic Assessment (PEA) on the Oko Gold Project with an effective date of 8 December 2025, and its mineral resource estimate (MRE) carries an effective date of 20 November 2025. That work covered resource zones including the Oko Main Zone and Ghanie.

The technical rigour of G2’s programme is not the issue. Under NI 43-101, GMIN’s own QP must independently assess and verify those figures before they can be classified as current under GMIN’s disclosure framework. Until that independent verification is complete, the figures remain historical, regardless of the quality of the work that produced them.

The three technical workstreams GMIN must complete before reclassification

GMIN has defined a sequenced verification programme rather than a vague commitment to “further work.” Three workstreams must be completed before the historical estimates can be reclassified, and each addresses a specific gap between the inherited G2 data and the larger combined project GMIN is now evaluating.

1. Data consolidation: Combining all data from the Oko-Ghanie Project with data from GMIN’s adjacent Oko West Project, creating a unified dataset across the enlarged land package.
2. Combined geological modelling: Building geological models that span both project areas, reflecting the geological relationships across the combined footprint rather than treating the two projects as separate entities.
3. Additional drilling: Conducting drilling campaigns to infill data gaps, test geological continuity between the two project areas, and generate modern QP-reliant data that supports the combined resource model.

Each workstream is necessary because GMIN is not simply re-running G2’s analysis. The inclusion of Oko West means the verification exercise is building a combined resource model across a larger project area, requiring new data and new modelling.

Upon completion of these workstreams, GMIN has stated that a press release will be issued reflecting the combined mineral resources of the Oko-Ghanie Project and the Oko West Project. That announcement will, by regulatory necessity under NI 43-101, reflect the work and judgement of GMIN’s Qualified Person.

Knowing what each workstream involves helps investors distinguish substantive progress updates from cosmetic ones. An announcement about data consolidation completing, for instance, signals a genuine milestone. An announcement about “ongoing work” without specifying which workstream it advances does not.

GMIN’s three-step disclosure pathway to a certified combined resource

The verification workstreams feed into a defined disclosure sequence. Each step builds on the last, and each delivers a discrete increase in the regulatory standing of the Oko-Ghanie figures.

1. Combined resource press release: Issued once data consolidation, geological modelling, and additional drilling are complete. This is the point at which the Oko-Ghanie figures transition from historical estimates to QP-certified current mineral resources under NI 43-101.
2. NI 43-101 technical report (within 45 days): Canadian securities regulations require a supporting technical report to be filed within 45 days of the combined resource press release. This report provides the full technical documentation behind the resource figures.
3. Follow-up technical study (targeting 2027): A further NI 43-101 technical report focused on mine plan optimisation, covering mining sequences, production rates, and throughput for the combined projects.

The logic is cumulative. Step 1 resolves the historical classification. Step 2 certifies it with full technical documentation. Step 3 adds the operational layer that tells investors what a mine based on that resource could look like.

What the 2027 technical study will and will not tell investors

The 2027 report is a distinct NI 43-101 technical report, separate from the combined resource report in Step 2. Its focus is mine plan optimisation: determining the optimal mine plan, sequencing, and throughput for the combined projects.

Investors should note what the 2027 report is not designed to do. The historical classification question is resolved at Step 1 (the combined resource press release) and certified at Step 2 (the supporting technical report). The 2027 study builds on that certified foundation, adding the operational planning layer that represents a materially higher level of project definition.

How to read the Oko-Ghanie figures responsibly right now

The Oko-Ghanie historical figures provide directional context about project scale and grade. They are legitimately useful as an indicative framing of the opportunity GMIN has acquired.

They are not, as of 29 July 2026, a bankable, certified resource base.

GMIN’s Qualified Person has not verified the Oko-Ghanie figures for use as current mineral resources. Investors must not treat them as current mineral resources or reserves.

The underlying G2 technical work carries specific effective dates: MRE effective 20 November 2025; PEA technical report effective 8 December 2025. Three milestones are worth monitoring: advances in the data consolidation and geological modelling workstreams, the timing of the combined resource press release, and the subsequent 45-day NI 43-101 technical report filing.

The regulatory logic behind GMIN’s disclosure is investor protection, not project doubt

NI 43-101’s requirement to distinguish historical from current estimates exists for one reason: to prevent investors from relying on figures that have not been independently validated under the acquiring company’s own Qualified Person. The framework is a safeguard, not a signal of geological weakness.

GMIN’s disclosure follows exactly the pattern the system is designed to produce. The company completed the acquisition, identified the classification gap between the inherited G2 figures and NI 43-101’s requirements for current resources, disclosed that gap clearly, and defined the verification pathway to close it.

The verification workstreams ahead are the mechanism by which the Oko-Ghanie Project transitions from an acquired geological opportunity to a certified, investable resource base. The data consolidation, combined modelling, and additional drilling are not regulatory box-ticking; they are the technical foundation upon which a QP-certified combined resource will stand.

Investors who understand how NI 43-101 classification works are better positioned to read any mining company’s disclosure language and to distinguish genuine project risk from standard regulatory process.

The Oko-Ghanie story is still in its early chapters

The Oko-Ghanie figures are directional context, not certified resources, and the path from one to the other is defined and underway. Three technical workstreams (data consolidation, combined geological modelling, additional drilling) feed into a three-step disclosure pathway (combined resource press release, NI 43-101 technical report within 45 days, and a 2027 mine plan optimisation study).

The 2027 NI 43-101 technical report, if delivered on schedule, could represent the point at which GMIN’s Oko-Ghanie acquisition transitions from a geological thesis to an operationally defined project. Until then, the regulatory framework is working as intended, and informed investors will track the milestones accordingly.
