  • Advanced, second stage bench testing program is about to commence
  • Gen 2 PUREVAPtm Quartz Reduction Reactor (“QRR”) reactor, 1/250 scale model of the planned 200 tonnes per annum (tpa) Pilot Plant will be operational in the coming weeks

MONTREAL, QUEBEC–(Sept. 19, 2017) – HPQ Silicon Resources Inc (“HPQ”) (TSX VENTURE:HPQ)(FRANKFURT:UGE)(OTC PINK:URAGF) is pleased to advise shareholders that an advanced, second stage bench testing program is about to commence. PyroGenesis Canada Inc (PyroGenesis) has informed HPQ that the Gen 2 PUREVAPtm Quartz Reduction Reactor (“QRR”) reactor, 1/250 scale model of the planned 200 tonnes per annum (tpa) Pilot Plant will be operational in the coming weeks.

Bernard J. Tourillon, Chairman and CEO of HPQ Silicon stated, “The design and construction of the Gen 2 PUREVAPtm QRR is another exciting step toward commercialization and is a result of the collaborative efforts of PyroGenesis and HPQ. Building on our success to date the Gen 2 PUREVAPtm QRR will allow for further refinements to the silicon purification and testing of the numerous process improvements now planned for the Pilot Plant. This will greatly de-risk our project and provide valuable information sooner as we continue to make the process adjustments needed to produce Solar Grade Silicon Metal.”


The first generation batch lab scale PUREVAPtm QRR (now referred to as Gen 1 PUREVAPtm) was built to prove the concept that quartz could be transformed in one step into Silicon Metal (Si), for the solar panel industry. A series of tests using the Gen 1 PUREVAPtm were ordered (September 2, 2016 PR) to generate key technical data required for the design of the 200 tpa pilot plant capable of producing Solar Grade Si (SoG Si). The Gen 1 PUREVAPtm process succeeded, demonstrating significant impurity removal, in one step, transforming low purity SiO2 (Quartz) into 3N+ Purity Si (99.97% Si) (May 16, 2017 PR, January 26, 2017 PR, November 29, 2016 PR, November 2, 2016 PR and September 29, 2016 PR). This product exceeds the highest purity level of the Metallurgical Grade Silicon Metal (Mg Si) industry, a US$5.5 billion dollar per year industry1.

Our next key milestone is to produce quantities of solar grade silicon for testing of its electrical characteristics, sending material to industry participants and finalize Pilot plant design en route to commercialization. CEO Bernard Tourillon commented, “Our Gen 1 PUREVAPtm was a great success and we believe the reactor will eventually make its way to a science and engineering hall of fame. It has currently reached its maximum operational efficiencies and nothing more could be gained by additional tests.”


The Gen 2 Purevapâ„¢ QRR will focus on Process Refinement, Characterization, Metallurgical Testing and purity improvements using the new semi-continuous feed 1/250 scale pilot-plant (May 4, 2017, PR).

Based on Gen 1 PUREVAPtm results, PyroGenesis completed the detailed engineering and design of the 200 tpa pilot plant, including substantial process modifications. Gen 2 PUREVAPtm therefore is an upgraded version of the Gen 1 Purevaptm that will be a true 1/250 scale replica of the planned larger pilot plant (Gen 3 PUREVAPtm). The Gen 2 PUREVAPtm is undergoing final manufacturing, assembly and testing and will be operational during the first weeks of October 2017.

The start of this new metallurgical testing program using The Gen 2 PUREVAPtm represents major de-risking of the Pilot Plant program for the following reasons:

  • Gen 2 will allow specific process design improvements and modifications derived from Gen 1 PUREVAPtm test work to be implemented and perfected;
  • The Gen 2 produces larger silicon Metal (Si) samples to test improvements to the purification process;
  • Gen 2 allows an intermediate step in scaling up to the Pilot Plant, mitigating that scaling up risk;
  • Gen 2 will allow the following Milestones to be reached sooner than originally planned;
    • Producing larger Si samples for testing by potential purchasers;
    • Allows HPQ and Pyrogenesis to test the electrical parameters of the High Purity Si;
    • Produce enough material to send samples to Solar industry participants;
    • Provide data to demonstrate the economics of PUREVAPâ„¢ QRR.


We are pleased to join HPQ in announcing both reaching this new milestone and commencing the second stage testing program,” said P. Peter Pascali, President and CEO of PyroGenesis. “I also wish to commend the team, both at PyroGenesis and HPQ, for having persevered through the many challenges to date and for all the discoveries they made along the way (the ability to transform low purity Quartz into 3N+ Silicon Metal in one step at lab scale not being the least of them). As we have said in the past, it will not be a straight line to success, but given the results to date we are more confident then ever before that we will have a commercial success. What level of success, is yet to be determined. As in all projects, delays will occur, but I firmly believe we are on the right track to have a significant impact in the high purity silicon and solar markets.


Further to our June 23, 2017 press release, the company continued to work with PyroGenesis and a number of specialized laboratories on silicon analysis protocols. Specifically, efforts focus on analytical procedures, certification, and analysis turn around time. We are working with our partners to resolve the analytical bottlenecks.

Results will be reported in a comprehensive report on the proof of concept and phase one process characterization and metallurgical testing programs, being prepared by PyroGenesis.

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). 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.
