MM8 Secures Last Approval, Starts Underground Mine Development

Medallion Metals (ASX: MM8) has spent 18 months assembling every piece of the regulatory puzzle for its Ravensthorpe Gold Project. As of early August 2026, the last piece is in place. The company has secured its final government approvals, completing a permitting framework that now clears the legal path to underground mine development at the Kundip Mining Centre in Western Australia. For junior gold developers on the ASX, the transition from “subject to approvals” to “approvals in hand” is one of the most consequential de-risking events a project can achieve. What follows breaks down what the completed approval suite means, when shareholders can expect boots on the ground and ore in the plant, and why the stock’s 70% gain over the past year may represent only the first chapter.

From permitting story to execution story: what the final approvals actually mean

The single largest binary risk for any junior miner is statutory approval. Projects can be redesigned and re-financed, but they cannot legally proceed without regulatory consent. As of early August 2026, that risk has been removed from Medallion Metals’ ledger entirely.

The completed approval suite spans both federal and state levels, with no further primary environmental consents outstanding. Three components make up the package:

• EPBC Act approval (federal): Granted 3 February 2026, covering the sulphide production plan and underground mining operations. The company described this as the final primary environmental approval required.
• Mining Development and Closure Plan (MDCP) (state): The Western Australian instrument enabling commencement of box-cut excavation and underground development at Kundip.
• Section 45C amendment to Ministerial Statement 1143 (state): The complementary WA instrument completing the regulatory package.

The investor framing shifts accordingly. Regulatory risk, the kind that can permanently strand capital, has been largely replaced by executional risk: whether management can deliver on time and on budget. That is a categorically different and generally more manageable risk profile.

Managing Director Paul Bennett stated that securing these approvals completes the foundational phase of the project and shifts the company’s priority to disciplined operational delivery.

The 18-month permitting journey and the project it produced

Approvals did not arrive in isolation. The 18-month permitting window doubled as a construction period for every other element a development-ready project requires: a technically robust resource, a funded capital stack, and a guaranteed sales channel for concentrate.

Resource confidence and capital-efficient infrastructure

The sulphide Mineral Resource Estimate stands at 0.95Moz gold equivalent at 5.2 g/t AuEq, comprising 0.84Moz Au and 37kt Cu contained. Published in August 2025, the majority of metal sits in the Indicated category following an 18,000m drilling programme. Additional 2026 drilling at Gem and other KMC lodes continues to target resource-to-Indicated conversion and mine plan strengthening.

The Cosmic Boy Concentrator (CBC) is an existing processing facility whose utilisation significantly reduces upfront capital intensity compared with building a new plant. Front End Engineering and Design (FEED) for CBC modifications was nearing completion as of the March 2026 quarterly report.

The Trafigura funding and offtake arrangement

A US$50 million senior secured prepayment facility from Trafigura, accompanied by a 7-year copper-gold concentrate offtake agreement, provides both development capital and a guaranteed sales channel for initial production. Medallion reported an A$65.3 million cash balance at the end of the March 2026 quarter. Drawdown of the Trafigura facility is targeted for the second half of CY2026, subject to conditions precedent.

The result is a project that arrives at development commencement with funding locked in, a technically de-risked resource, and concentrate offtake in place, a combination that distinguishes it from many junior developers who secure approvals but remain reliant on further capital raises.

Nine months to first ore: the development roadmap shareholders will be watching

With approvals in hand, the execution clock starts. Three defined milestones now give investors a clear scorecard against which to assess management delivery:

1. Kundip box-cut excavation and underground development commencement, targeted early Q3 CY2026 (August 2026), now that the MDCP has been obtained.
2. Cosmic Boy Concentrator modifications completion, with FEED nearing finalisation as of March 2026.
3. First delivery of Ravensthorpe ore to CBC, scheduled Q2 CY2027.

The approximately nine-month window between development start and first ore delivery constitutes the core execution phase. Development rates, cost control, and concentrator modification completion will all be tested against guidance in real time.

First delivery of Ravensthorpe ore to the Cosmic Boy Concentrator is scheduled for Q2 CY2027, the milestone that would turn the development story into a production story.

Ongoing 2026 drilling at Gem and other KMC lodes is expected to run in parallel, targeting resource conversion and mine plan strengthening. These results could provide incremental catalysts as the underground development advances.

What the 70% share price gain tells investors about where the value now sits

The numbers are clear. Medallion Metals shares appreciated approximately 70% over the prior 12-month period to approximately August 2026. Over the same timeframe, the ASX All Ordinaries Index (XAO) gained roughly 2%.

MM8 shares gained approximately 70% over the prior 12 months, against an approximate 2% gain for the ASX All Ordinaries Index over the equivalent period.

That outperformance reflects the milestones already delivered: permitting progress, the 0.95Moz AuEq resource upgrade, a positive FID, and a funded capital stack. The market has progressively repriced MM8 as each binary risk was removed.

The question for current and prospective holders is what remains unpriced. The forward value drivers that have yet to be earned include:

• Development performance versus guidance: Whether box-cut and underground advance rates match the stated timeline.
• Grade delivery at start-up: Whether realised grades and recoveries confirm the resource model once ore reaches the concentrator.
• Resource extensions from ongoing drilling: Whether 2026 programmes at Gem and other KMC lodes convert additional material to Indicated and expand the mine plan.

The gap between what is already priced in and what must still be delivered is where risk and opportunity intersect. Understanding this distinction is essential for anyone evaluating MM8 as a current or prospective position.

How to read a junior miner’s permitting milestone (and why this one matters more than most)

For junior miners, regulatory approval functions as a binary gate. A project can be redesigned, re-scoped, or re-financed, but it cannot legally commence without statutory consent. That is why permitting milestones are value-inflection events rather than administrative checkboxes.

Medallion’s approval package spans two distinct regulatory layers, and understanding each is useful for assessing future permitting news across the ASX mining sector.

The federal layer: EPBC Act approval

The Environment Protection and Biodiversity Conservation Act 1999 (EPBC Act) is Australia’s primary federal environmental framework. Obtaining approval under the EPBC Act signifies that the proposed activity has been assessed against national biodiversity and environmental impact standards and cleared for commencement. The EPBC approval granted 3 February 2026 covered the sulphide production plan and was described as the final primary environmental approval required.

The state layer: MDCP and Section 45C amendment

The Mining Development and Closure Plan (MDCP) is the Western Australian instrument that specifically enables commencement of physical development activity, including box-cut excavation and underground mine development at Kundip. The Section 45C amendment to Ministerial Statement 1143 is the complementary state-level instrument.

The three components together form the complete core regulatory clearance:

• EPBC Act approval: Federal environmental consent covering underground mining operations and the sulphide production plan.
• MDCP: WA state instrument enabling physical development commencement.
• Section 45C amendment: Complementary WA state instrument completing the package.

This particular permitting completion carries more weight than a single-approval milestone because it represents the full primary package required for underground development, with no further primary consents outstanding.

Medallion Metals enters the development phase with a clear scorecard

Medallion Metals now sits in the category of a permitted, funded junior developer where the investment thesis stands or falls on execution. The regulatory gates are cleared. The capital stack is assembled. The offtake agreement is signed.

Three near-term milestones form the practical scorecard over the next nine months: underground development commencement at Kundip in Q3 CY2026, completion of Cosmic Boy Concentrator modifications, and first ore delivery to CBC in Q2 CY2027. Ongoing drilling, CBC modification progress, and development ramp-up rates are the catalysts that will define the next leg of the story.
