VRX Silica’s updated 2026 Bankable Feasibility Study for Arrowsmith North confirms robust economics with an ungeared NPV8 of A$179.2 million and binding offtake contracts securing nearly 1 million tonnes annually.
- Ungeared NPV8 of A$179.2 million over 25-year mine life
- Proved and Probable Ore Reserve of 221 million tonnes at 99.5% SiO2
- Capital expenditure estimated at A$74.5 million with 4.6-year payback
- Conditional binding offtake contracts for 960,000 tonnes per year
- 1 for 5 renounceable rights issue to raise up to A$6.2 million
Updated BFS Confirms Strong Project Economics
VRX Silica Limited (ASX:VRX) has delivered another vote of confidence in its Arrowsmith North Silica Sand Project, unveiling a 2026 updated Bankable Feasibility Study (BFS) that underpins the development of a world-class silica sand operation. The study reveals an ungeared net present value (NPV8) of A$179.2 million based on a 25-year mine life, anchored by a substantial Proved and Probable Ore Reserve of 221 million tonnes grading 99.5% SiO2. This positions Arrowsmith North as a long-life, high-purity producer targeting the expanding Asian foundry and glass markets.
The BFS update incorporates a comprehensive re-tendering of capital and operating costs following the strategic relocation of the processing plant to the adjacent Arramall freehold property. Despite an overall capital expenditure increase of approximately A$8.3 million compared to the 2024 update, the project maintains strong capital efficiency with an estimated payback period of 4.6 years. Key cost savings stem from reduced site clearing, road construction, and a shorter haulage distance to Geraldton Port, partially offset by higher prices for OEM components and construction materials.
Advancing Approvals and Environmental Strategy
Regulatory momentum continues with mining and environmental approvals largely secured. The company has received mining proposal approval from the Western Australian Department of Mines, Petroleum and Exploration, environmental approval from the Minister for the Environment, and works approval for plant construction from the Department of Water and Environmental Regulation. An amended offset strategy involving the purchase of the 2,091-hectare Arramall farm site is nearing finalisation, reducing environmental impact by minimising native vegetation disturbance and enabling the installation of a solar farm to lower power costs and emissions.
This relocation and offset approach follows VRX’s earlier conditional contract to acquire the Arramall site, a move that has been highlighted as a significant cost and sustainability win for the project. The site’s proximity to Brand Highway facilitates efficient transport logistics to Geraldton Port. VRX’s proprietary vegetation direct transfer (VDT) mining and rehabilitation methodology further strengthens its environmental credentials, promising superior restoration outcomes post-mining.
Offtake Commitments and Market Positioning
Backing the project’s commercial viability, VRX has secured conditional binding contracts for 960,000 tonnes per annum of silica sand products, predominantly foundry sand, with customers across South Korea, Taiwan, the Philippines, and China. These contracts form a solid foundation for initial production volumes and reflect strong demand in Asia-Pacific markets, where supply shortages of high-quality silica sand are expected to tighten further.
The company’s product suite includes four distinct silica sand grades tailored to the foundry and glassmaking industries, which demand stringent specifications on purity, grain size, and hardness. VRX’s conservative pricing assumptions, ranging from US$38 to US$43 per dry metric tonne FOB, leave room for upside given prevailing upward pricing pressures in the market.
Capital Raising to Propel Project Development
To advance Arrowsmith North towards a Final Investment Decision (FID), VRX has launched a 1 for 5 renounceable rights issue priced at 4 cents per share, aiming to raise up to A$6.2 million before costs. The offer includes a free attaching option for every two new shares subscribed, exercisable at 10 cents until 30 June 2028. The rights issue is partially underwritten up to A$2 million by Mahe Capital, the lead manager and underwriter. Proceeds will fund early works, detailed engineering, and the Arramall property acquisition, as well as support ongoing development activities at the Muchea silica sand project and working capital needs.
While the company anticipates funding the bulk of the approximately A$74.5 million capital expenditure through a mix of equity, debt (up to A$60 million), and prepaid offtake, no final funding decisions have been made. The rights issue represents a discount of 18.4% to the last closing price and 27.3% to the 90-day VWAP, reflecting a pricing strategy to encourage shareholder participation.
These funding efforts build on recent capital raises and debt financing preparations, including the appointment of Pareto Securities to manage debt arrangements, and follow VRX’s earlier major offtake deals that underpin the project’s commercial foundation.
Long-Term Resource Base and Strategic Outlook
Arrowsmith North’s Ore Reserve and Mineral Resource estimates remain consistent with prior updates, supporting a mine life exceeding 100 years at current production rates. The project’s location outside sensitive heritage and conservation areas, combined with advanced approvals and infrastructure planning, lays the groundwork for a sustainable and economically viable operation.
VRX’s broader portfolio includes the ultra-high-grade Muchea project near Perth and the Boyatup project near Esperance, both advancing towards production readiness. The company actively explores additional silica sand and downstream processing opportunities across Australia, aiming to capitalise on the growing global demand for high-purity silica sand, especially in the renewable energy and high-tech glass sectors.
Investors will be watching closely as VRX navigates the next critical phases of project financing and execution, with the upcoming FID and regulatory amendments on the processing plant relocation at Arramall key milestones. The company’s ability to secure full funding and maintain offtake momentum will be pivotal in translating the robust BFS economics into operational reality.
Bottom Line?
VRX’s updated BFS and capital raise set the stage for a pivotal year, but securing full funding and finalising regulatory amendments remain critical hurdles before Arrowsmith North can transition from study to production.
Questions in the middle?
- Will VRX secure the full A$60 million debt facility anticipated for project funding?
- How will ongoing global supply chain pressures, including the Middle East conflict, impact final capex and opex?
- Can VRX expand offtake contracts beyond the current 960,000 tonnes to support ramp-up to full production?
