Maritana Minerals Clears Final Permit Hurdle Paving Way for First Gold in H2 2027
Key Takeaways
- Maritana Minerals has secured all three statutory approvals required for full construction of the Black Swan Processing Hub, with the final Native Vegetation Clearing Permit granted by LGIRS on 19 September 2026.
- The early works agreement with GR Engineering Services has been extended to 31 October 2027, adding an A$6.5 million commitment on top of the existing A$25.0 million already committed.
- Long-lead procurement is actively advancing on critical path items including elution columns, CIL bolted tanks, intertank screens, and platework packages — locking in equipment before the EPC contract is finalised.
- Boorara mining restart is targeted for mid-2027 to supply ore to the 2.5Mtpa processing hub, with first gold production targeted for H2 CY2027.
- A 60,000-metre resource conversion drilling campaign is continuing across the Maritana Kalgoorlie project area to upgrade inferred resources into higher-confidence categories that can underpin mine plans.
All permits secured as Black Swan Processing Hub clears final regulatory hurdle
Maritana Minerals (ASX: MRT) has secured the final statutory approval needed for full construction of the Black Swan Processing Hub (BSPH), a 2.5Mtpa processing facility located approximately 50km northeast of Kalgoorlie in the Western Australian Goldfields. The Native Vegetation Clearing Permit (NVCP), granted by LGIRS on 19 September 2026, was the last approval required. With all permits now in place, the company has also extended its early works agreement with GR Engineering Services (ASX: GNG) to 31 October 2027 at an additional committed cost of A$6.5 million, adding an A$6.5 million commitment to the existing A$25.0 million commitment. First gold is targeted for H2 CY2027.

Q4 CY2026 construction milestones — what’s now in place
The final approval that unlocks full construction
The BSPH required three statutory approvals before construction of the process plant could proceed. All three have now been granted:
- Mining Development and Closure Proposal — approved by DMPE on 27 July 2026
- Works Approval for the carbon-in-leach circuit — granted by DWER on 5 August 2026
- Native Vegetation Clearing Permit (NVCP) — granted by LGIRS on 19 September 2026
The NVCP was the final piece of the regulatory puzzle. All statutory approvals and permits required for construction of the process plant are now in place.
For investors, this matters beyond the headline. Regulatory risk — the possibility that a missing permit halts or delays a project mid-build — has been one of the most common destroyers of construction timelines in Australian mining. With every approval secured before the Engineering, Procurement and Construction (EPC) contract is finalised, Maritana can proceed to full construction without the threat of regulatory interruption.
Early works extended — A$6.5 million additional commitment on top of existing A$25.0 million to keep construction momentum
The early works agreement with GR Engineering, originally announced on 20 July 2026 with a committed expenditure of A$25.0 million, has been extended to 31 October 2027. The extension adds an additional committed cost of A$6.5 million, adding an A$6.5 million commitment to the existing A$25.0 million commitment.
The purpose of extending the agreement is to maintain continuity of detailed engineering, long-lead procurement, demolition and bulk earthworks while the EPC contract for the process plant is finalised. Long-lead procurement is advancing across several critical path items:
- Elution columns
- CIL bolted tanks
- Intertank screens
- Platework packages
Long-lead procurement refers to equipment and materials that require extended manufacturing and delivery times. Delays here cascade into the broader project schedule, so locking in these items early is a genuine risk management measure, not just a formality.
Grant Haywood, Managing Director and CEO
“The Native Vegetation Clearing Permit (NVCP) was the last statutory approval required for the full processing plant; this is a significant milestone for Maritana and the development of the Black Swan Processing Hub in preparation for first gold in H2 CY2027.”
What is a processing hub — and why does the BSPH model matter for investors?
A central processing hub is a single, large-scale facility that receives ore from multiple nearby mines rather than each mine building its own dedicated plant. The economic logic is straightforward: shared infrastructure means lower capital cost per tonne of ore processed, and a single hub can draw on ore from different deposits as they come online or ramp up.
The BSPH, at 2.5Mtpa capacity, is designed to service ore from the Maritana Kalgoorlie project area. As additional deposits reach development-ready status, the hub model allows that ore to be directed into existing processing infrastructure rather than requiring fresh capital expenditure.
The permit sequencing also carries a specific message for investors. In Australian mining, statutory approvals are routinely the longest lead-time item in a project’s development. Securing all required approvals before EPC contract finalisation means construction can advance on engineering and commercial timelines rather than regulatory ones. That sequencing, now complete, removes a category of risk that often surfaces unexpectedly in comparable projects.

Boorara restart and the road to first gold
Mining restart at Boorara is targeted for mid-2027, providing ore supply to the BSPH once the processing facility is operational. A 60,000 metre resource conversion campaign is continuing across the Maritana Kalgoorlie project area. Resource conversion drilling upgrades inferred resources (lower-confidence estimates) into indicated or measured categories (higher-confidence estimates that can underpin mine plans and production schedules).
The pathway to first gold can be tracked through a sequence of milestones now actively in progress:
| Milestone | Detail | Date / Target | Status | Significance |
|---|---|---|---|---|
| NVCP granted | Final statutory approval | 19 Sep 2026 | Complete | Clears all regulatory hurdles |
| Early works extended | GR Engineering agreement | To 31 Oct 2027 | Active | A$6.5M additional commitment |
| EPC contract | Process plant construction | Being finalised | In progress | Locks in full construction scope |
| Boorara mining restart | Ore supply to BSPH | Mid-2027 | Targeted | Feeds processing hub |
| First gold | BSPH production | H2 CY2027 | Targeted | Key investor milestone |
Grant Haywood, Managing Director and CEO
“Extending the early works agreement with GR Engineering to 31 October 2027 keeps the engineering, long-lead procurement, on-site works and construction activities running while the EPC contract is being finalised.”
With all statutory approvals secured, an additional A$6.5 million committed to early works on top of the existing A$25.0 million commitment, long-lead procurement advancing on critical path items, and Boorara restart targeted for mid-2027, Maritana’s timeline to first gold in H2 CY2027 is now supported by a clear, permit-free construction pathway.
