ASX Announcement 28 July 2025 June 2025 Quarterly Activities Report Highlights: Office of the Appeals Convenor confirms completion of appeal process for Arrowsmith North WA Minister for Environment confirms adequacy of EPA assessment process and Arrowsmith North Silica can proceed without further assessment Awaiting formal notification from Minister approving the Arrowsmith North project Proposal VRX Silica Limited (VRX or Company) is pleased to provide this activities report for the June 2025 quarter. Arrowsmith North Environmental Approval VRX has continued to focus on progressing approvals for the development of the Company’s 100% owned Arrowsmith North Silica Sand Project (Proposal), approximately 270km north of Perth in Western Australia. In early January 2025 the Environmental Protection Authority of Western Australia (EPA) published its Assessment Report (Report) for the Proposal and recommended to the Minister for the Environment that the Proposal may be implemented, subject to conditions that had been accepted by VRX following consultation with the EPA. Publication of the Report triggered commencement of a three-week review period during which appeals against the content and recommendations in the Report may be submitted to the Office of the Appeals Convenor (OAC). An appeal was lodged in late January 2025, and the OAC commenced its investigation on behalf of the Minister for the Environment, in consultation with the appellant, EPA, the Company and other public authorities or individuals with an interest in the subject matter of the appeal.

Geothermal Energy Dandaragan Geothermal Energy Permit, 145km north of Perth, WA The Company is actively assessing other silica sand and downstream processing projects in Australia. During the quarter, in early May 2025, the OAC confirmed to VRX that its investigation into the appeal was complete and the OAC had provided its report to the Minister for Environment. The report by the OAC can be downloaded at: https://appeals-system.appealsconvenor.wa.gov.au/search-appeals/ In late June 2025, VRX received confirmation from the Minister for the Environment that he had determined the EPA assessment of the Proposal was adequate, consistent with the policy framework and implementation of the Proposal can proceed without further assessment. The Minister advised that he had considered the information available, including the EPA response to the appeal, the appellant’s submissions, VRX’s response to the appeal, advice from the Department of Biodiversity, Conservation and Attractions, and the OAC’s report and recommendation. The Minister allowed the appeal in part and accepted the OAC’s recommendations to amend conditions addressing dieback. VRX had previously considered and accepted the amendment. This determination by the Minister is final and cannot be appealed. It serves as an important step in the environmental approvals process as VRX moves towards development of Arrowsmith North. The Company now awaits formal notfication from the Minister to approve the Proposal under Part IV of the Environmental Protection Act 1986. Arrowsmith North has the potential to support a new, long-term industry for Western Australia with substantial benefits to the State and Mid West region including long-term direct and indirect employment opportunities and royalties. The project has considerable support from a range of stakeholders, including local indigenous groups, local shires, the Mid West Development Commission, the Mid West Chamber of Commerce & Industry and State and Federal Governments. It boasts robust economic metrics for the supply of multiple silica sand products for a growing Asian market. Arrowsmith North Offtake VRX has offtake interest under non-binding term sheets for the supply of an aggregate of 640,000 tonnes of AFS20, 35 and 55 certified foundry sand and Mid Wst Premium glass sand. Indicative pricing is within the range of the Company’s financial modelling for Arrowsmith North as provided in the updated bankable feasibility study (BFS) for the project announced to ASX on 6 March 2024. Key assumptions for the BFS include a target price range of US$38-43 per dry metric tonne, dependent on product type, product quality, contract terms and quantity, and a targeted production schedule of 2.2 million tonnes per annum over the full mine life with a conservative ramp up from a minimum 800,000 tonnes to 1.1 million tonnes per annum in years 1 and 2. The offtake parties are all significant suppliers in their respective countries. Namgwang Casting Materials Ind Co., Ltd and Woori Corporation, are leading suppliers of sand to the foundry industry in South Korea. Yamakawa Sangyo Co., Ltd is a leading supplier to the foundry industry in Japan. FarnHwa Enterprise Co., Ltd is a leading supplier of foundry and glassmaking sand in Taiwan. Strong interest in silica sand products from Arrowithsmith North remains, as potential offtake partners await final approvals. Discussions continued during the quarter with existing and new potential partners. 2 Arrowsmith North Project Financing During the quarter the Company continued to explore project financing alternatives, including debt and offtake finance for Arrowsmith North. VRX has mandated Argonaut PCF to act as the Company’s financial advisor in connection with potential debt financing for Arrowsmith North. In the light of progress towards conclusion of the environmental approvals process for Arrowsmith North, interest from potential debt financiers has increased markedly and the Company is finalising an independent technical review for the project.

Silica sand is the most used commodity on the planet after air and water. It is the main ingredient in all types of glassmaking, including specialty solar panel and hightech glass, and foundry casting. It is a finite resource that is running out, with the Asia-Pacific region experiencing an evergrowing supply shortfall that is driving up prices. Arrowsmith is located 270km north of Perth. Arrowsmith North boasts a minimum 25-year mine life capable of producing more than 2Mt tonnes per year of highgrade (99.7% SiO2)* silica sand for export to the foundry, container glass and flat glass markets in Asia, with permitting well advanced, and will lead production. Muchea, located 50km north of Perth, is an ultra-high-grade (99.9% SiO2)* silica sand project capable of producing sand required for ultra-clear glass for solar panels and other high-tech glass applications. Boyatup, located 100km east of Esperance, is under development and capable of producing sand for the glass market. *Information relating to grades are extracted from releases to ASX on 28 August 2019, 11 November 2022 and 6 March 2024 (Arrowsmith North) and 18 October 2019 (Muchea). The company is not aware of any new information or data that materially affects this information. 7 Rule 5.5 Appendix 5B Mining exploration entity or oil and gas exploration entity quarterly cash flow report Name of entity VRX SILICA LTD ABN Quarter ended (“current quarter”) 59 142 014 873 Consolidated statement of cash flows 1.
