• Provided interim progress report to HPQ Silicon Resources highlighting GEN2’s significantly higher silicon metal production yield
• A new operational parameter that increases the Pure Silicon Metal Production Yield¹ of the PUREVAP™ Quartz Reduction Reactor and (ii) a test using the GEN2 PUREVAP™ was completed

MONTREAL, April 25, 2019 (GLOBE NEWSWIRE) — PyroGenesis Canada Inc. (http://pyrogenesis.com) (TSX-V: PYR) (OTCQB: PYRNF) (FRA: 8PY), a high-tech company, (the “Company”, the “Corporation” or “PyroGenesis”) that designs, develops, manufactures and commercializes plasma atomized metal powder, plasma waste-to-energy systems and plasma torch products, today announced that it has provided an interim progress report to HPQ Silicon Resources (“HPQ”), highlighting GEN2’s significantly higher silicon metal production yield.

PyroGenesis informed HPQ that (i) the technical team identified a new operational parameter that increases the Pure Silicon Metal (Silicon Nugget) Production Yield¹ of the PUREVAP™ Quartz Reduction Reactor and (ii) a test using the GEN2 PUREVAP™ was completed which together provided the following information:

1. The PUREVAP™ reactor can be modified from a stationary reactant² mixtures load to a dynamic one, without affecting other key operational parameters of the reactor which, as a result, improves production yield significantly;
2. That changing the reactant mixture load to a dynamic flow positively affects Production Yield;
3. That it is feasible to modify the GEN3 PUREVAP™ Pilot Plant to integrate these advantages into the new design.

IMPROVING REACTANT FLOW IN THE REACTOR SIGNIFICANTLY IMPROVES PRODUCTION YIELD

The scope of the potential of the new parameter became apparent when the test produced the largest single individual silicon nuggets of all tests to date; weighing ~ 6.5 grams.

REACTOR MODIFICATION MORE THAN DOUBLES SILICON METAL NUGGET (PURE SILICON) PRODUCTION YIELD

Comparing³ the 3.3% pure silicon nugget production yield of test #14 to the 7.0% pure silicon nugget production yield obtained by test M-001 validated the modification potential. Further tests will be needed to optimize the process and its operation, but the results clearly indicate that pure silicon production yield more than doubled with the modification. Producing 4N+ silicon with the PUREVAP™ assumes a 90%+ production yield at commercial scale. These results are part of our trendline that indicate that we are on the right track to reach that goal with our GEN3 PUREVAP™ Pilot Plant.

“It has always been important to maintain or improve production yield while scaling up to a commercial system,” said Mr. Pierre Carabin, Chief Technology Officer and Chief Strategist of PyroGenesis. “Being able to improve it, with results such as today’s, and thereby further mitigating the risk of the project, is a significant achievement in itself, and it validates the decision to proceed with the GEN2 middle step. We have ticked off another box in our goal to create both a low cost and green metallurgical approach to producing solar grade silicon metal.”

GEN2 PUREVAP™ QRR CONTINUES TO BE AN INVALUABLE BENCH TEST PLATFORM

These latest results confirm the strategic decision to incorporate the GEN2 as a middle step towards the GEN3 pilot plant. It provides us the ability to immediately test new concepts and design modifications using the GEN2 PUREVAP™ platform while the GEN3 PUREVAP™ pilot plant is being assembled. This unique proposition not only reduces the risk profile of the project, but it also reduces the project commercial validation timeline. It is also extremely cost effective since tests done using the GEN2 R&D platform are substantially less expansive then they would be if the tests were done using the GEN3 PUREVAP™ pilot plant.
