Allup Silica (APS.AX) released the results from its metallurgical test program completed on the Sparkler Silica project. Those tests have confirmed the company is able to produce SiO2 with an average grade of 99.7% with only 84 ppm Fe2O3 (and some aluminum and titanium values as deleterious elements), which makes the silica amenable for use in photovoltaic applications (which requires a SiO2 grade of in excess of 99.5% and a Fe2O3 grade of less than 100 ppm).
