- Interest is building in WA copper and critical minerals assets with clear development pathways
- Develop Global’s Trafigura-backed funding and offtake package puts mid-tier copper plays in focus
- Juniors with infrastructure, scale, technical clarity and momentum are better placed to win capital
Copper’s next investment cycle is being driven less by bullish sentiment and more by the hard limits of project delivery.
Demand remains robust, but supply is struggling to keep pace. New discoveries are rare, development timelines are stretching out, and capital is increasingly selective about where it deploys.
The result is a more profound market focus on projects that offer more than simple copper exposure.
Strategic investors are prioritising assets with grade, infrastructure, restart potential or technical momentum, projects that can be de-risked as credible development options without waiting decades to come to fruition.
For WA copper hopefuls, the funding environment is tougher but also more constructive for those able to demonstrate real project momentum.
Companies with established resources, a history of mining, strong logistics or district-scale potential now have a clearer window to demonstrate how they fit into the next phase of supply.
GreenTech Metals (ASX:GRE) CEO James Rattenbury said that it was already changing how investors and funders thought about the sector.
“We’ve seen a shift in focus from strategics and funding providers,” Rattenbury said.
“They’ve realised that to facilitate the pipeline of projects, they need to come in earlier and support projects through de-risking, rather than only putting an offtake agreement in place as part of project financing.”
He said that shift could put projects such as Whundo in a stronger position.
“Large-scale greenfields copper discoveries can take decades to discover and de-risk,” Rattenbury said.
“Smaller historical projects, including VMS-style deposits like Whundo, have a role to play because they can offer high grades, scalability and a more de-risked base.”
Filling the gap
GreenTech has built a West Pilbara base metals position around Whundo and Munni Munni, giving it exposure to copper, zinc, PGMs and nickel in a region with established roads, ports, power and mining services.
Whundo already has a JORC 2012 indicated and inferred resource of 6.2Mt at 1.12% copper and 1.04% zinc.
The next step is to test whether the project has more value than the resource currently captures.
GreenTech is drilling to confirm gold and silver credits across the orebody, which have not yet been included in the resource.
By September, Rattenbury expects a clearer view of Whundo’s upside as those credits and shoot extensions are added to the picture, potentially shifting the development case beyond copper grade alone.
GreenTech widens the lens
And Munni Munni adds further depth to GreenTech’s portfolio.
The project is best known for platinum-palladium, with a historical JORC 2004 estimate of 23.6Mt at 2.9g/t 4E for 2.2Moz that GreenTech is working to validate and restate under JORC 2012.
But Rattenbury said the company was looking at Munni Munni through a more extensive copper and polymetallic lens.
“Munni Munni is known as a high-grade platinum reef, but GreenTech sees a much broader copper opportunity across the 225km2 intrusive,” he said.
“There is copper associated with the platinum reef, copper in the surrounding halo and a larger geochemical copper signature across the intrusive.”
Copper was not a focus of previous exploration, making its discovery by GRE another layer to the Munni Munni proposition.
Munni Munni now brings a layered mafic intrusion and the surrounding land package under one explorer. Combined with Whundo, this lifts GreenTech’s West Pilbara footprint to more than 500km2.
The deal also gives GreenTech access to 21km of Ferguson Reef strike, where historical drilling has outlined continuous PGE-copper-nickel mineralisation.
Rattenbury said investors should watch whether GreenTech’s bulk-system approach – incorporating sulphide zones and using a net smelter return cut-off that captures copper, nickel and PGEs – can support a larger resource and a more scalable development case.
Pilbara advantage
Location remains central to the funding equation.
With cost inflation, permitting delays and infrastructure bottlenecks derailing many juniors, the Pilbara is regarded as an advantage.
GreenTech’s Whundo project sits beside a highway and about 60km by sealed road from Karratha.
Rattenbury said the Pilbara’s established industrial base was central to GreenTech’s positioning.
“The Pilbara has established infrastructure, access and existing mining operations,” he said.
“There has also been extensive prior mining and exploration, which gives GreenTech a strong base for further work rather than starting from a greenfields position.”
GreenTech still has funding, approvals and technical work ahead, but its Pilbara infrastructure advantage gives funders something tangible to lean into as copper scarcity sharpens the hunt for faster development options.
From exposure to execution
GreenTech could well have the right project in the right location at the right time.
Its push to accelerate exploration comes hot on the heels of major US$400m funding deal from global trading giant Trafigura, which will help Bill Beament’s Develop Global (ASX:DVP) progress two projects.
One is the Pioneer Dome lithium mine near Norseman, with the other the brownfields Sulphur Springs copper-zinc project in the Pilbara.
For advanced developers, defined resources, credible technical studies and offtake potential at present provide a more direct route to demonstrating financeability.
Brownfields and historical projects are also finding new openings in a stronger copper market – LME copper is at an historically strong US$13,371/t while zinc is up ~30% in the past year at US$3492/t.
GreenTech could be well placed to latch onto this narrative. Other WA copper hopefuls, including Caravel Minerals (ASX:CVV), are also better placed as the market looks for projects that can turn scale, technical work, approvals and strategic interest into a fundable development pathway.
Caravel is a large beast, a low grade project that could run upwards of 60,000tpa. While it will carry a higher capital cost, the porphyry already has real ballast behind it, with Indian conglomerate Adani on board as a proposed offtaker.
Strategic capital is targeting projects that fit supply chains, deliver products buyers need, offer a clear development path for funders and sit in jurisdictions where construction and operations are viable.
Sulphur Springs is a useful marker for this shift.
Artemis tests the frontier
There remains optimism among firms searching for true companymaker copper discoveries as well. Artemis Resources (ASX:ARV) has established gold resources in the Pilbara, but its most exciting asset could be a greenfields copper exploration play in the frontier Madura province.
Its backers seem to understand the strategy, with Artemis recently securing firm commitments for an $8m placement cornerstoned by Jupiter Asset Management, to fund gold and copper exploration across its portfolio.
The immediate focus is the aforementioned Madura, east of Kalgoorlie, where Artemis has built a 2100km2 belt-scale position and is preparing maiden drilling at the Cassowary IOCG target, pending heritage clearance.
Sharon Dam, supported by EIS co-funding through Red Metal (ASX:RDM), adds a second copper-gold target.
That gives Artemis a different proposition: exposure to the possibility of a new copper-gold province emerging under cover, rather than a conventional near-mine development story.
Executive director Matthew Greentree said the Develop Global-Trafigura deal reinforced copper’s strategic importance and showed major trading houses were willing to back high-quality Australian projects.
“It also underscores the premium being placed on district-scale opportunities in emerging copper provinces,” he said.
While Madura is still early stage, Greentree said it offered scale, a favourable jurisdiction and a clear path to first drilling.
Early exploration is unlikely to prove an economic discovery on its own, but it can test whether Madura has the alteration, structures, host rocks and geochemical signals needed to support a fertile IOCG-style system.
“The first holes are designed to answer critical questions regarding the nature of the source bodies, alteration systems and structural controls,” Greentree said.
“Even if the first holes do not intersect significant mineralisation, they will provide valuable information that can rapidly improve targeting across the broader project area.”
Magnetic data, iron-rich alteration and early copper hits at Cassowary or Sharon Dam would help shape the next round of drilling and could lift interest in the targets.
