VRX Silica secures Arrowsmith site as Muchea resource expands

Arrowsmith North advances despite approval slippage

VRX Silica Limited (ASX:VRX) has moved its proposed Arrowsmith North processing plant onto firmer ground, completing the purchase of the adjacent 2,091-hectare Arramall farm and securing a 21-year general purpose lease for the site. The more immediate constraint is regulatory: final amendments needed for the plant relocation were not completed during the September quarter after regulators requested additional information.

“Arrowsmith North Project Area”

VRX now expects the approval process to finish in the current quarter. The company said it does not expect further material delays to the overall schedule and is still targeting early trial shipments in early 2028. The Arramall site is intended to host the processing plant, access roads, stockpiles, water infrastructure and a potential solar farm, while reducing native vegetation disturbance compared with the originally approved location.

The project holds a 221 million tonne proved and probable ore reserve grading 99.5% SiO₂. However, the timetable remains dependent on the completion of the regulatory amendments, detailed engineering, early works and financing. The latest filing says the 2026 Updated BFS estimates capital expenditure of approximately A$74.5 million for a 2 million tonne per annum processing plant, with no required project capital yet secured.

Strategic capital supports early works, not construction

During the quarter, VRX completed the previously announced A$4.5 million strategic placement, with Nebari Natural Resources Credit Fund II providing approximately A$3.5 million and Delphi group a further A$1 million. Nebari held 10.46% of VRX after the issue, while Delphi’s undiluted interest stood at 13.66%.

The funds supported the Arramall purchase and are earmarked for early works, detailed engineering, Muchea activities and working capital. The quarterly cash flow report recorded A$4.548 million in equity proceeds, A$2.041 million in borrowings and A$5.009 million of investing outflows. VRX finished the quarter with A$4.364 million in cash and reported estimated funding of 3.22 quarters at the period’s operating and exploration expenditure rate.

That cash position is measured against near-term corporate and project-development spending, not the full construction bill. VRX said it continues to engage potential funding partners and is considering a mix of equity, debt and prepaid offtake for Arrowsmith North. The company’s earlier project case included six binding offtake agreements covering 960,000 tonnes per annum, but the funding required to turn that commercial position into a producing operation remains unresolved.

Muchea lease expands high-grade resource footprint

“Muchea project area (post-land swap)”

Muchea delivered a more concrete tenure milestone after the quarter closed, with Mining Lease M70/1414 granted for 21 years as part of VRX’s land swap proposal. Combined with the retained M70/1390 area, the revised project area is intended to provide access to a substantially larger volume of high-grade sand across land the company says has a lower environmental impact.

VRX reports a 208 million tonne JORC-compliant Muchea Mineral Resource grading 99.6% SiO₂. The project is being positioned around ultra-clear glass and other downstream products, including silica flour and powder for applications ranging from solar-panel encapsulants and specialised glass to semiconductor-related manufacturing. The company plans to submit environmental, mining and other regulatory referrals during this and the next quarter, followed by an update to Muchea’s 2019 bankable feasibility study in 2027.

The Muchea land swap, which was previously backed by the Western Australian Government, also changes the practical question facing the project: not whether the resource is large, but whether VRX can progress the approvals, technical studies and downstream case without stretching its funding capacity. At Arrowsmith North, the next decisive evidence will be the approval outcome and a finance package capable of closing the gap between early works and construction.
