Gen2 PUREVAP Tests Restarting, Early Warrant Exercise Program Results

MONTREAL, July 19, 2018 -- HPQ Silicon Resources Inc (“HPQ”) (TSX Venture:HPQ) is pleased to notify shareholders that PyroGenesis Canada Inc (“PyroGenesis”) (TSX Venture: PYR) has completed a scheduled audit of the Gen2 PUREVAP™ equipment for wear and tear following the first 14 tests of our ongoing Commercial Scalability Proof of Concept testing program. The audit helped identify critical operational parameters for the Gen3 PUREVAP™ pilot equipment and allowed the evaluation of additional design modifications that could be implemented for further tests using the Gen2 PUREVAP™.

Gen2 PUREVAP™ TESTING RESTARTING

The Gen2 PUREVAP™ equipment having been refurbished, re-assembled and incorporating the latest design modifications, is now ready to start a new series of at least 8 additional tests focused on:

• Increasing the Yield¹ and the Production Yield² of the Gen2 PUREVAP™ above test #14 results;
• Testing the Purity of the Si produced using ICP-OES³ from both our low purity feed stock (98.84% SiO₂) and specifically sourced ultra high purity feed stock (> 99.9% SiO₂);
• Finding the optimum operation conditions for the Gen2 PUREVAP™ and gaining information about future Gen3 PUREVAP™ operation.

Bernard J. Tourillon, Chairman and CEO of HPQ Silicon stated, “Our Gen2 PUREVAP™ testing program has successfully pushed the project from the lab to a semi-industrial scale. We have leaned a lot and our data driven, empirical and methodical approach is de-risking our project as we move toward demonstrating to industry participants the commercial scalability of our PUREVAP™ QRR process and its unique capacity of converting quartz into Si, while simultaneously increasing its purity toward the purity required for the solar industry. Our objective for 2018 continues to be building on our technical successes as we get ready to commence the Gen3 PUREVAP™ Pilot Equipment phase with our “Solar Silicon Team” of Pyrogenesis and Apollon Solar, as well as, building market awareness of our progress and plans.”

EARLY WARRANT EXERCISE INCENTIVE RESULTS

On June 13, 2018, HPQ announced its intention to implement a warrant exercise incentive program between June 18, 2018 and July 17, 2018 in order to encourage the early exercise of up to 6,674,600 out of the 12,305,000 of its outstanding unlisted 7 cents warrants. At the close of the period the Corporation is happy to announce that 4,152,000 (62%) of the eligible outstanding unlisted 7 cents warrants were exercised and that the Corporation received $290,640 in gross proceeds. The 2,522,6000 eligible warrants that were not exercised during the early exercise period remain outstanding and continue to be exercisable for shares of the company on their current terms.

As a result of the early exercise program, the company will be issuing 4,152,000 share purchase warrants entitling the holder to purchase one additional share of HPQ for a period of 18 months from the date of issuance at a price of 17 cents, subject to a four-month hold period from the date of issuance. The warrants issued under the incentive program are subject to the receipt of all regulatory approvals, including the final approval of the TSX-V.

HPQ CHAIRMAN AND CEO INCREASED HIS HOLDING IN HPQ SILICON

Bernard Tourillon, HPQ Chairman and CEO used the early warrants exercised to invest $50,050 in HPQ and increase his holding by 715,000 shares and 665,000 share purchase warrants, entitling the purchase one additional share of HPQ for a period of 18 months from the date of issuance at a price of 17 cents in accordance with the incentive warrant exercise program.
