Homerun Resources Inc. Patent Application for Antimony-Free High-Purity Silica Glass Composition for Solar Glass Applications
Homerun advances its antimony-free glass patent roadmap while continuing to face persistent liquidity constraints.
Homerun Resources Inc. announced a patent application (PCT/BR2026/050512) for an antimony-free soda-lime-silica glass composition tailored for photovoltaic solar panels and high-transparency industrial applications. The formulation replaces traditional antimony-based refining agents with sulfur trioxide (SO₃) to eliminate air bubbles, reducing toxic heavy metal leaching risks and meeting restrictive international environmental standards.
The process achieves ultra-low ferric oxide (Fe₂O₃) levels below 0.020% using high-purity purified silica, removing the need for chemical bleaching agents. The composition retains standard physical-chemical properties, ensuring compatibility with existing commercial float glass production lines. Applications include photovoltaic solar panel encapsulation, architectural float glass, optical components, electronic display covers, and automotive uses. The patent will be published in the "Revista de Propriedade Industrial" (Industrial Property Gazette) of INPI Brazil.
Homerun Resources Inc. (HMR) filed a patent application as part of its ongoing intellectual property protection strategy, following a Bankable Feasibility Study completed in May 2026, a letter of intent with SORG Group, a partnership with CEITEC, and a collaboration with UC Davis. The filing validates the technical pathway for producing antimony-free solar glass, aligning with emerging regulatory trends from the EU Ecolabel and the US EPA. However, the patent does not de-risk the more than $400 million in capital expenditure required for plant construction.
Projections from the Bankable Feasibility Study remain unchanged, with a net present value of $670 million and an internal rate of return of 20.2%. The patent does not alter the financial model, construction timeline, or financing requirements. The release aligns with the company’s stated vertical integration roadmap but provides no new capital, revenue, or near-term operational catalysts.
Homerun Resources Inc. faces a working capital deficiency of $195,299 and holds only $482,150 in cash. The patent does not address the immediate liquidity crunch or the explicit going concern flag.
Homerun Resources Inc. (HMR) is developing a vertically integrated, silica-powered clean energy platform in Bahia, Brazil. Its flagship project is a 1,000-tonne-per-day antimony-free solar glass manufacturing plant in Santa Maria Eterna, designed to be Latin America's first dedicated facility.
The company controls over 200 million tonnes of high-purity silica sand (>99.6% SiO₂) across three fully permitted leases. Its strategic verticals include high-purity silica processing, solar glass manufacturing, silica-based thermal energy storage (Enduring system with NREL), and AI-enabled energy management solutions.
Key partnerships include SORG Group (technology/provider), CEITEC (semiconductor SiC development), UC Davis (laser purification), and NREL (thermal storage IP).
