Announcement PDF ASX Announcement 1 July 2026 Management and Board Update VRX Silica Limited (VRX or Company) (ASX: VRX) is pleased to announce the finalisation of its management succession plan, with Tony Swiericzuk formally commencing in the role of VRX chief executive officer on a full time basis today, 1 July 2026. As announced to ASX on 23 December 2025, the Company implemented the succession plan to allow for an orderly transition to new leadership following Bruce Maluish indicating his intention to retire from the managing director role in the medium term. Mr Swiericzuk, a seasoned mining executive with over 30 years of leadership experience and a distinguished career including in large scale mines and bulk ports, commenced in the CEO role on a part-time basis on 1 February 2026, allowing him to transition into the role and wind down from other engagements in that interim period. Given his significant experience in mining, and deep industry knowledge and contacts in silica sand markets, particularly in Asia, Mr Maluish has agreed to remain with the Company and moves to a non-executive director role as from today, 1 July 2026. In another change at Board level, long-standing VRX Chairman Paul Boyatzis has decided to retire from the role with effect from the end of yesterday, 30 June 2026, to coincide with the end of the financial year and as part of a broader wind- down of his ASX-listed company roles over recent years. Non-executive director, Peter Pawlowitsch, will step into the role of Interim Chairman as the Company commences its search for a permanent replacement for Mr Boyatzis. Mr Pawlowitsch commented: “I am delighted that Tony Swiericzuk is formally commencing as full-time CEO of VRX as we look towards the construction phase of our Arrowsmith North silica sand project early next year and accelerating development of our world class Muchea silica sand project. “Tony is ideally-placed to take on this challenge and has the deep mining industry knowledge and experience to lead the Company from explorer to producer. “I also take this opportunity to thank Paul Boyatzis and Bruce Maluish for their many years of service to VRX, with both of them having been with the Company since the 2011 IPO.” ASX: VRX Capital Structure Shares on Issue: 850.5 million Options on issue: 87.7 million Corporate Directory Peter Pawlowitsch Interim Non-Executive Chairman Tony Swiericzuk Chief Executive Officer Bruce Maluish Non-Executive Director David Welch Non-Executive Director Ian Hobson Company Secretary Silica Sand Projects Arrowsmith Silica Sand Projects, 270km north of Perth, WA.

About VRX Silica Limited VRX Silica Limited (ASX: VRX) is the most advanced pureplay silica sand company listed on the ASX, developing its 100% owned silica sand projects at Arrowsmith (North, Brand and Central), Muchea and Boyatup in Western Australia. Silica sand is the most used commodity on the planet after air and water. It is the main ingredient in foundry casting and in all types of glassmaking, including specialty solar panel and high-tech glass. It is a finite resource that is running out, with the Asia-Pacific region experiencing an ever-growing supply shortfall that will drive up prices in the long term. VRX has significant Resources to underpin very long-life silica sand projects. 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 high-grade (99.7% SiO2)* silica sand for export to the foundry, container glass and flat glass markets in Asia, with first production planned for late 2027. Muchea, located 50km north of Perth, is a very 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 27 May 2026 (Arrowsmith North) and 18 October 2019 (Muchea).
