MONTREAL, QUEBEC–(Marketwired – Nov. 1, 2017) – HPQ Silicon Resources Inc (“HPQ”) (TSX VENTURE:HPQ)(FRANKFURT:UGE)(OTC PINK:URAGF) is pleased to inform its shareholders that PyroGenesis Canada Inc (“PyroGenesis”) has submitted to HPQ a report entitled “Final Report-Silicon Metal Purity Enhancement” pertaining to the final series of the 96 metallurgical tests completed using the Gen 1 PUREVAPtm Quartz Reduction Reactor (“QRR”). The effect of various operating parameters on the final purity of the Silicon Metal produced was rigorously tested. The findings validated the concept, and extrapolating the results suggests that under a semi-continuous PUREVAPtm process, we can transform Quartz (SiO2) into Silicon Metal (Si) with purity levels acceptable to the solar wafer industry (4N+ or 99.998% Si)1. The recently commenced Gen 2 PUREVAPtm metallurgical testing program aims to confirm this and to allow us to make samples for downstream product testing as we finalize plans and prepare to assemble the Pilot Plant.
