McLaren builds WA titanium story from Eucla sands

Promising resources developer McLaren Minerals is looking less like a freshly rebranded junior and more like a small-cap building serious mineral sands muscle from the broad, flat country of WA’s Eucla Basin.

The company began its life on the ASX as Allup Silica, with its original flagship Sparkler silica sands project in WA’s Great Southern region, backed by a broader early-stage silica portfolio that included the Pink Bark project near Esperance and its Cabbage Spot prospect in the Kimberley.

The decisive turn came in August 2024, when Allup acquired the McLaren heavy mineral sands project, 150km east of Norseman and 42km west of Balladonia.

The deal shifted the company’s focus from high-purity silica sands to titanium-bearing heavy minerals and ultimately gave the renamed McLaren Minerals a flagship asset more suited to the extensive mineral sands experience of its managing director, Simon Finnis and non-exec Peter Secker.

The shift has quickly changed the company’s scale and prospects. Less than a year later, McLaren was sitting on a 529-million-tonne JORC-compliant indicated and inferred resource grading 4.5 per cent heavy minerals for 23.7Mt of in-situ heavy minerals.

It has also since completed a pre-feasibility study and a 13,000m drilling campaign, feeding its next stage of resource upgrade and expansion work.

The appeal in McLaren’s project case is not hard to spot. Its project spans 333 square kilometres of advanced heavy mineral sands ground on crown land in a mining-friendly state, within 2km of the Eyre Highway and linked by 350km of sealed road to WA’s port of Esperance.

The company says the mineralisation is shallow, broad and continuous, with free-flowing sands well suited to conventional bulk mining and processing. In mineral sands, that mix of scale, access and simplicity can matter almost as much as grade.

McLaren’s February prefeasibility study gave the story its first proper economic frame, outlining a 15.9-year mine life, a pre-tax net present value of $252.2M, an internal rate of return of 26 per cent, a life-of-mine EBITDA of $899.7M and a payback period of 3.7 years.

Under a base-case scenario, the mine would process 186 Mt at 5.85 per cent heavy minerals, little more than one-third of the total resource. That leaves the balance of the resource outside the company’s initial mine inventory for further testing, optimisation, expansion, or later set-aside.

The planned primary product from McLaren is sulphate ilmenite, a titanium feedstock used mainly in titanium dioxide pigment but also linked to titanium metal and industrial applications.

McLaren says its concentrate has the flexibility to feed sulphate pigment production and potentially chloride slag processing, while titanium’s use in aerospace, defence and energy technologies adds a strategic angle as titanium feedstocks attract growing critical-minerals attention.

A current drilling campaign is aimed at turning that broad story into a tighter bankable-feasibility dataset. The program was designed to upgrade parts of the resource from indicated to measured, lift selected blocks of inferred material to indicated status, support a maiden ore reserve and test other likely extensions, including the company’s Eastern Shoreline target.

The program has already thrown up the sort of eye-catching results that catapulted McLaren back onto Bulls N’ Bears’ Big Hits radar only 10 days ago. The company reported bonanza peak heavy mineral grades up to 34.6 per cent, with standout intercepts including 22m from surface at 7.62 per cent heavy minerals in one hole in the south-eastern extension area.

A second hole in the same emerging area delivered 24m from surface at 4.75 per cent heavy minerals, while drilling within the broader resource returned 24m from surface at 8.01 per cent heavy minerals.

The key point is not just the shine in the peak numbers, but where they sit within the mineralised envelope. The headline drill intercepts all start from surface. The first holes in the south-eastern extension lit up strongly enough for McLaren to put in another 12 follow-up holes on a 300m-by-300m spacing, with assays still pending.

By mid-June, drilling had reached 9768m across 551 holes, representing 75 per cent of the planned program. Managing director Simon Finnis has pointed to the consistency of mineralisation across the deposit as a confidence builder, rather than hanging the whole story on one or two strong intercepts.

Finnis also flagged a broader area of higher-grade mineralised sands in the northwest of the deposit that could have implications for the early years of any mining operation.

McLaren has not stopped at one project. In March, the company moved to add the Barossa zircon project in South Australia’s eastern Eucla Basin, identifying a 54km-long zone of zircon-rich mineral sands with associated rare earths potential from historical data.

Heavy mineral grades across the project area average an estimated 4.6 per cent, with mineralisation interpreted as stacked shoreline strandlines developed along an ancient regional palaeo-shoreline.

The project contains the Kalahari, Mojave and Gobi prospects, with more than 580 historical drill holes and high-grade zones assaying more than 10 per cent heavy minerals. McLaren says the valuable heavy mineral suite includes 16 per cent zircon, 60 per cent ilmenite and two per cent rutile, with monazite pointing to rare earths potential.

For now, the company’s McLaren heavy mineral project remains the main game, with the near-term work program aimed at completing phase-two drilling, collecting the pending assays, running metallurgical and variability test work, updating the mineral resource, moving into reserve estimation, and keeping the bankable feasibility study (BFS) workstreams moving.

As with all budding developments, funding is part of that equation. McLaren launched a fully underwritten share purchase plan after the March quarter to raise $1.5M, with funds earmarked for McLaren project BFS work, Barossa exploration and working capital.

For now, McLaren has the kind of intriguing profile that keeps a junior in the conversation. The company still has plenty of work ahead before it can claim a place among Australia’s next generation of mineral sands producers. However, the building blocks look to be falling nicely into place.

With a resource already measured in the hundreds of millions of tonnes, a bankable feasibility study gathering momentum and fresh drilling continuing to hint at even more upside, the company appears to be steadily shifting from explorer to developer.

If the pending assays and resource upgrade continue the trend, McLaren’s heavy mineral sands story could soon become much harder for the market to ignore.
