HPQ Silicon Resources Inc.: Final Gen 1 PUREVAP™ Purity Enhancement Test Identifies Pathways To Producing Solar Grade Silicon Metal with the Gen 2 PUREVAP™
November 1, 2017 (Source) — 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 PUREVAPtmQuartz 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.
Bernard Tourillon, Chairman and CEO of HPQ stated, “Results to date are spectacular, in less than 18 months the PUREVAP™ QRR process has demonstrated a one-step capacity to produce very pure Silicon Metal. Traditional industrial processes need to deploy multiple expensive steps to reach the same purity level. The Gen 2 PUREVAP™ will allow us to test, over the comings months, a number of purification options including slow cooling, as we continue our methodical metallurgical testing protocol. Our goal is straightforward, we seek to produce a Solar Grade Silicon Metal that can be used to manufacture solar cells as efficient as the one produced by Elkem Solar of Norway, the only commercially successful UMG Solar producer in the World.”
PYROGENESIS CEO REMARKS
“We are extremely happy with the Gen 1 PUREVAP™ results, however, this first-generation reactor was limited in its ability to push yield which directly relates to purity. The second stage testing program, or Gen 2 PUREVAP™, will allow us to test those limits, thereby increasing the probability of success when assembling the pilot plant”, said P. Peter Pascali, President and CEO of PyroGenesis. “We are pleased to join HPQ in announcing both the reaching of this new milestone and the commencing the second stage testing program.”

About HPQ Silicon
HPQ Silicon Resources Inc is a TSX-V listed resource company planning to become a vertically integrated and diversified Metallurgical Grade and Solar Grade Silicon Metal producer. Our business model is focused on developing a disruptive one step High Purity and Solar Grade Silicon Metal manufacturing process (patent pending). Solar Grade Silicon being the key ingredient required to transforms the sun energy into electricity.
HPQ plans to generate high yield returns and significant free cash flow within a relatively short time line. The process will have a greatly decreased carbon footprint, energy footprint, and will eliminate the use of the toxic chemical reagents and by products now in use by the current solar silicon production technologies, which fundamentally date from designs made in the mid 1900’s.
