2 May 2019 ASX ANNOUNCEMENT High Recoveries from Silica Sand Process Plant Design Highlights: • Confirmation of high recoveries of commercial silica sand products from Arrowsmith and Muchea Silica Sand Projects • Demand for these products strong across the Asia Pacific region. • Full catalogue of products available for customers VRX Silica Limited (VRX Silica or Company) (ASX: VRX) is pleased to announce the results of testwork and confirmation assays for recoveries of silica sand commercial products from its Arrowsmith (Arrowsmith), located 270km north of Perth, WA, and Muchea (Muchea), 50km north of Perth, WA Silica Sand Projects. The Company has now conducted three iterations of the testwork, with the final iteration completed in March of this year by CDE Global, a renowned testwork laboratory and process plant fabricator based in Northern Ireland. The Company has since completed confirmation assays on final products from that testwork through Nagrom Laboratories in Perth, WA. The Company recently released a process circuit design, engineering and cost estimate by CDE Global for a plant which was based on this testwork 1 and the final determination of recoveries is based on this circuit design, which included the attritioning step being conducted twice.1 Attritioning is a high energy interaction of grains rubbing on grains which liberates attached fine particles and reduces particle size by breakage on corners and grain boundaries. This reduces contaminants and improves particle shape. VRX Silica Managing Director Bruce Maluish said: “We are now confident in the process circuit design and the final silica sand products capable of production, which have been compiled into our products catalogue.” “We will continue to distribute our catalogue and gauge the response, which to-date has been extremely positive,” said Maluish. 1 See ASX announcement of 27 March 2019.

About VRX Silica VRX Silica Ltd (VRX Silica) (ASX: VRX) has significant silica sand projects in Western Australia. The Arrowsmith Silica Sand Project, located 270km north of Perth, comprises four granted exploration licences with one exploration licence and two mining lease applications pending. The Muchea Silica Sand Project, located 50km north of Perth, comprises one granted exploration licence, with one exploration licence and one mining lease applications pending. Testwork has confirmed a range of silica sand produc t s whic h are capable of production at both projects. Further work is underway to enable feasibility studies to be completed. The recently purchased Boyatup Silica Sand Project, located 100kms east of Esperance, comprises one granted exploration licence and since acquisition the Company has applied for an additional Exploration License to extend the holding. Initial indications are that this project will complement both Arrowsmith and Muchea while adding to the silica products VRX Silica will potentially produce. Also, in Western Australia, 40km south of Newman, is VRX Silica’s Warrawanda HPQ Project, which is prospective for high purity quartz and nickel sulphides. VRX Silica also has granted tenements at its Biranup Project, adjacent to the Tropicana Gold Mine in Western Australia’s Goldfields that are prospective for gold and base metals. Proven Management The VRX Silica Board and management team have extensive experience in mineral exploration and mine development into production and in the management of publicly listed mining and exploration companies.
