4 ANNUAL REPORT ALLUP SILICA Year Ending 30 June 2023 E70/5447 Sparkler A Metallurgical beneficiation of the Sparkler A sands produced a premium low-iron high-grade silica suitable for the “Ultra-Clear” glass used by the photovoltaic industry. The Company’s processing results show the beneficiated silica sand has an average grade of 99.8% SiO2, and most encouragingly 84ppm FeO2, below the “Ultra-Clear” specification of <100 ppm Fe2O3. In Q2 2023, consultants and leading global sand processing specialist, CDE Global were engaged with a bulk sample sent to their Lab in Northern Ireland for process plant design and scaling metallurgical testwork. Consultants Mining Plus have also been engaged to manage and complete the technical and environmental studies, and to draft the mining proposal and mine closure plans required to support the granting of the Mining Lease. E70/5920 Sparkler C The Company completed its maiden drill program, identifying high purity target areas for a follow-up drill campaign subject to approvals, which have now been granted. From the initial 30 auger samples taken across the target area, 21 holes returned results above the 98% cut-off, with the unprocessed raw sand achieving an average SiO2 grade of 96.6% and an average of 2094ppm Fe2O3.
