HPQ Silicon Welcomes Canada's Recognition of Silicon Metal as a Critical Mineral

MONTREAL, June 18, 2024 (GLOBE NEWSWIRE) -- HPQ Silicon Inc. ("HPQ" or the "Company") (TSX-V: HPQ) (OTCQB: HPQFF) (FRA: O08), a technology company specializing in green engineering processes for silica and silicon material production, is pleased to announce its support for the Government of Canada's latest expansion of the Critical Minerals List, which now recognizes Silicon Metal as a critical mineral resource key to domestic industry and security.

The news release, published on Monday, June 10th, 2024, summarizes the Government of Canada's Critical Minerals List. Announced by the Honourable Seamus O'Regan Jr. and Natural Resources Canada, the update highlights the growing importance of silicon metal in modern technologies that drive a low-carbon economy, including semiconductors, batteries, solar panels, and more.

The move will offer greater certainty for Canadian mining and manufacturing businesses while further building out the nation's capacity to meet the growing global demand for sustainably sourced minerals.

"We are thrilled that the Government of Canada has finally recognized silicon metal (Si) as a critical mineral," said Bernard Tourillon, President and CEO of HPQ Silicon. "This validates our strategic vision of developing the PUREVAPtm QRR technology, a new proprietary process to produce, in one step, a zero-carbon footprint, high purity silicon metal material. Our Innovative solutions will not only help meet the growing demand for high-purity silicon, it will also allow silicon metal manufacturing to evolve from being the largest emitter of CO2 among all metals and non-ferrous metal, based on tonnes (t) of CO2/t of product basis [1] to a manufacturing process that can help Canada and the world reach its carbon reduction targets. We are committed to advancing our technology and doing our part to ensure Canada realizes its full potential as a global mineral powerhouse."

Significance for HPQ Silicon

HPQ, leveraging its proprietary PUREVAPtm Quartz Reduction Reactor (QRR) technology, will benefit from the recognition of silicon's strategic importance. The company is well-positioned to play a leading role in being the only Company capable of supplying Canada and the world market with silicon materials with zero carbon footprint (June 27, 2023, release).

HPQ's PUREVAPtm QRR represents a significant breakthrough in silicon production; unlike traditional methods, which require large scale facilities for their multi-stage, energy-intensive, and polluting processes, the PUREVAPtm process is a small footprint scalable process that can efficiently convert raw quartz into high-purity silicon metal (3N+) in a single step, a material that is ideal for high-tech industries, including metallurgy, electric vehicles, aluminum alloys, silicones, renewable energy, battery storage, and electronics. Furthermore, the system reduces raw material input by approximately 25%, versus traditional process [2].

Finally since the QRR, by design, operates under controlled atmospheric conditions, this ensures that the CO gas ("Co(g)") generated during the carbothermic reaction remains unoxidized. Consequently, in addition to producing high purity silicon, the QRR also produces a gas composition enriched with CO(g), which can be readily captured and valorize by combining it with green hydrogen to produce valuable green synthetic fuels.

"This designation will likely unlock federal and provincial funding opportunities to bolster domestic supply chains for critical minerals, assisting HPQ in scaling its commercial operations," said Mr. Tourillon. "Adding silicon to the Critical Minerals List also serves as a strong market signal to investors and industry partners about the importance of a sustainable and reliable silicon supply chain."

PUREVAPtm QRR's Economic Advantage

The QRR's clear economic advantage over competing silicon metal production techniques empowers the repatriation of industry back to Canada's ESG-friendly markets. With the potential to displace dirty silicon production primarily produced overseas while supporting North American industrialization, the QRR offers an efficient and sustainable solution that aligns with Canada's decarbonization efforts.
