Medallion Metals Locks in $50M Fixed-Price Build Contract Targeting Q2 2027 Gold Output

Medallion Metals has locked in a binding $50 million lump sum EPC contract with GR Engineering for the Cosmic Boy Concentrator refurbishment — tracking exactly to feasibility study estimates and putting first gold production on course for Q2 2027.
By William Hadrian -
  • Medallion Metals has executed a binding $50 million lump sum EPC contract with GR Engineering Services for the Cosmic Boy Concentrator refurbishment — matching the $49 million feasibility study estimate almost exactly.
  • GR Engineering originally built Cosmic Boy in 2009, bringing deep institutional knowledge of the plant and Ravensthorpe mineralogy that materially reduces execution risk on the refurbishment.
  • Construction is already underway — GRES personnel and subcontractors are on site, earthworks are complete, and concrete pouring is expected to commence in the first week of September 2026.
  • Processing at Cosmic Boy is targeted to commence October 2026 on third-party ore under the Early Processing Strategy, with first mine production from Kundip targeted Q2 2027.
  • Progress is running in parallel at Forrestania, where second ball mill components arrive at Port of Fremantle on 17 September 2026 and early processing of third-party ore is expected to begin in early October 2026.

Medallion Metals locks in $50M EPC contract for Cosmic Boy Concentrator

Medallion Metals (ASX: MM8), through its wholly owned subsidiary Myamba Minerals Pty Ltd, has executed a $50 million lump sum Engineering, Procurement and Construction (EPC) contract with GR Engineering Services Limited (ASX: GNG) for the refurbishment and modification of the Cosmic Boy Concentrator (CBC). This is a binding contract, not a letter of intent, covering the full design, procurement, construction and commissioning of a standalone facility capable of producing copper concentrate and gold doré from Ravensthorpe Gold Project ore at a targeted throughput of 650,000 tonnes per annum.

The $50 million contract value sits in line with the $49 million estimate from the Ravensthorpe Gold Project Feasibility Study, providing early confirmation that costs are tracking to plan. It replaces the preceding $7.6 million Early Works Agreement (EWA) that commenced in June 2026, under which front-end engineering and design (FEED) was completed and long-lead items were ordered.

Managing Director Paul Bennett

“The contract value has been agreed in line with the Feasibility estimate and on terms that provide cost certainty. Its execution is another important operational step that brings us closer to production.”

Why GR Engineering is the right partner for this build

The selection of GR Engineering Services (GRES) is not a cold-start relationship. GRES originally designed and constructed Cosmic Boy in 2009, bringing detailed institutional knowledge of the existing plant and extensive familiarity with Ravensthorpe mineralogy. That history makes the transition from FEED to full EPC considerably lower risk than bringing in a new contractor at this stage.

Key indicators that the project is already in motion:

  • GRES completed the FEED programme under the Early Works Agreement
  • Long-lead items are being procured and are progressing
  • Site earthworks for the expanded plant footprint are complete
  • GRES personnel and subcontractors are already on site
  • Concrete pouring is expected to commence in the first week of September 2026

The transition from FEED to full EPC scope is underway, with the same contractor already mobilised on site.

What is an EPC contract and why does it matter for investors?

An Engineering, Procurement and Construction (EPC) contract means a single contractor takes full responsibility for designing the facility, sourcing all materials, and physically building it. The “lump sum” structure is the critical detail for investors: the price is agreed at $50 million, providing cost certainty through to commissioning.

This contrasts with the earlier Early Works Agreement, which was a preparatory phase covering FEED and site readiness. The EPC is the full build. For Medallion shareholders, the practical implication is cost certainty from here to commissioning, removing one of the most common sources of financial risk in mine development projects.

Development advancing across both project sites

Progress is running across both the Forrestania Gold Project (FGP) and Ravensthorpe Gold Project (RGP). The table below captures the current status and near-term timelines at each site.

Site Key Milestone Status Timeline
Forrestania (FGP) Surface earthworks Complete —
Forrestania (FGP) Second ball mill components In transit Arrive Port of Fremantle 17 Sep 2026
Forrestania (FGP) Early Processing (third-party ore) Stockpiling underway Processing expected early Oct 2026
Ravensthorpe (RGP) Box cut excavation Preparation underway Scheduled to commence Sep 2026
Ravensthorpe (RGP) Mine development / first production Infrastructure relocating First production targeted Q2 2027

At Ravensthorpe, civil works and infrastructure readiness activities are progressing ahead of the box cut excavation. Accommodation rooms are being relocated from Forrestania to the Ravensthorpe camp, and mine offices and underground infrastructure are being relocated from Spotted Quoll to RGP in preparation for mine development.

The near-term production sequence is now clearly defined. Processing at Cosmic Boy is expected to commence in October 2026, initially on third-party ore under the Early Processing Strategy, while mine development at Kundip advances towards first production targeted in Q2 2027.

Why did Medallion Metals choose GR Engineering for the Cosmic Boy refurbishment?

GR Engineering Services originally designed and constructed the Cosmic Boy Concentrator in 2009, giving them detailed institutional knowledge of the existing plant and Ravensthorpe mineralogy — they also completed the front-end engineering and design under the preceding Early Works Agreement and already have personnel on site.

How does the $50 million EPC contract compare to the feasibility study estimate?

The executed EPC contract value of $50 million is in line with the $49 million estimate from the Ravensthorpe Gold Project Feasibility Study, providing early confirmation that project costs are tracking to plan.
