Message: HPQ Gen2 Testing Confirms PUREVAP™ Process Can Significantly Reduce the Cost of Making Silicon Metal by Lowering Raw Material Costs
MONTREAL, June 17, 2019 -- HPQ Silicon Resources Inc. – (www.HPQSilicon.com) (TSX-V: HPQ), (OTCPink: URAGF), (FWB: UGE) is pleased to announce the receipt of a report from PyroGenesis Canada Inc (“PyroGenesis”) (TSX-V: PYR) comparing the performance of the PUREVAP™ Quartz Reduction Reactor (QRR) process using a low cost highly reactive carbon source, versus conventional processes used by all the Metallurgical Grade Silicon Metal (Mg Si) producers such as Ferroglobe, Dow-DuPont, Elkem, Rima and Rusal, which use high cost, higher purity carbon sources.
PUREVAP™ CAN MAKE 99+% SILICON USING ONE REDUCTANT: LOWER COST HIGHLY REACTIVE CARBON
Having a process that uses less feedstock to make 1 MT of Mg Si and allows the substitution of costly high purity Reductant with readily available lower cost material will reduce the cost of making Mg Si, giving that process a competitive advantage, which is what the PUREVAP™ QRR can offer.
As part of the ongoing R&D, PyroGenesis decided to push the envelope of the process by using only one Reductant, a highly reactive carbon source (92.1% Total Carbon) and HPQ off spec SiO2 (98.839% VS 99.83%), Fe2O3 (0.121% VS 0.05%) and Al2O3 (0.182% VS 0.04%) in the Gen2 PUREVAP™ reactor1.
In this test, Gen2 PUREVAP™ produced commercially viable 99.73% Si with 0.166% Fe and 0.0424% Al, representing chemical grade Mg Si2, a product with great commercial value. By comparison, PyroGenesis calculated that similar material input in a conventional smelter would produce 96.95% Si, a product with little commercial value.1
“These results are a testament to our methodical approach, the Gen2 PUREVAPTM QRR platform has allowed us to check off this tremendous major milestone. These spectacular results are not only further de-risking the project, they are also opening up additional segments beyond solar energy applications where HPQ PUREVAPTM QRR could have direct application,” stated Bernard Tourillon, President and CEO of HPQ Silicon Resources Inc. “Market research indicates that demand for chemical grade Mg Si will drive demand for Mg Si from 2.8 Million MT worth US$ 7.5 B in 2018 to 3.8 Million MT worth US$ 12B by 20233. HPQ is very well positioned to benefit from this increase in demand.”
A PUREVAP™ QRR PROPRIETARY ADVANTAGE: REDUCING RAW MATERIAL COSTS TO MAKE Si
Depending on the producer, making Mg Si (98.0% to 99.5% Si) in 2018 cost between US$ 1,450/MT and US$ 2,000/MT4. More than 40% of that cost5 (US$ 580/MT to US$ 800/MT) is directly attributable to the 6+ metric tonnes of raw material (SiO2 and Reductant) needed to produce 1 MT of Mg Si6.
The carbon reductant used in traditional processes to make Mg Si accounts for 30% of the total cost3. That cost is divided between two different sources, woodchip counting for 10% (US$ 145/MT to US$ 200/MT) and Carbon (low ash coal & charcoal) counting for 20% (US$ 290/MT to US$ 400/MT).
For conventional process producers, high purity coal procurement and cost have been identified as critical elements for their operations because: a) there are only 2 coal mines in the world that can supply it (the 100% Ferroglobe-owned Blue Gem Coal and Colombian coal)7; and B) a US$ 10/MT increase in its cost has a US$ 13 per MT produced impact on the producer’s bottom line7.
GEN2 TEST WORK INDICATES POTENTIAL SAVINGS, GEN3 PILOT PLANT WILL VALIDATE SCALE AND SCOPE OF SAVING
While being able to use lower cost raw material represents significant potential cost savings, the other biggest factor that differentiates the PUREVAP™ QRR is that it should be capable of using highly reactive carbon as Reductant, and therefore only need to process 4.5 MT of raw material8 (lower purity SiO2 and cheaper Reductant) to produce 1 MT of Mg Si.
As more than 40% of the cost of conventional processes is directly attributable to the 6+ metric tonnes of raw material (SiO2 and Reductant) needed to produce 1 MT of Mg Si3, it is possible to estimate that a PUREVAP™ QRR could cut in half raw material cost, representing a 20% reduction in the cost of making chemical grade Mg Si.
Gen3 pilot plant testing will allow us to refine and validate these numbers at commercial scale.

About HPQ Silicon
HPQ Silicon Resources Inc. is a TSX-V listed resource company that focuses on becoming the lowest cost producer of Silicon Metal and a vertically integrated and diversified High Purity, Solar Grade Silicon Metal (SoG Si) producer and a manufacturer of multi and monocrystalline solar cells of the P and N types, required for production of high performance photovoltaic conversion.
HPQ’s goal is to develop, in collaboration with industry leader PyroGenesis (TSX-V: PYR) the innovative PUREVAP™ “Quartz Reduction Reactors (QRR),” a truly 2.0 Carbothermic process (patent pending), which will permit the transformation and purification of quartz (SiO2) into Metallurgical Grade Silicon Metal (Mg Si) at prices that will propagate it clean energy potential.
HPQ’s goal, working with industry leader Apollon Solar, is also to develop a metallurgical approach to producing Solar Grade Silicon Metal (SoG Si) that will take full advantage of the PUREVAP™ QRR production of high purity silicon metal (Si) in one step and reduce by a factor of at least two-thirds (2/3) the costs associated with the transformation of quartz (SiO2) into SoG Si. The pilot plant equipment that will validate the commercial potential of the process is on schedule to start in 2019.
