Homerun Resources Inc. Announces Future Production of 100% Antimony-Free Solar Glass in Brazil

Vancouver, British Columbia--(Newsfile Corp. - October 8, 2025) - Homerun Resources Inc. (TSXV: HMR) (OTCQB: HMRFF) ("Homerun" or the "Company") is pleased to announce that our technical partners in the Belmonte (BA) Solar Glass Manufacturing project have confirmed that the exceptional purity of the silica sand from the Company's resources in the Santa Maria Eterna District will allow the Company to offer customers a portfolio of solar glass that is 100% free of added antimony compounds.

In traditional solar glass manufacturing, antimony improves refining, prevents oxidation of iron ions, resulting in higher transmittance and fewer defects. However, the global solar industry is at an inflection point. Concerns are rising about the environmental toxicity and recyclability challenges posed by antimony, a heavy metal flagged by the USEPA as hazardous at even minuscule concentrations. Leading regulatory bodies in Europe and the U.S. are increasingly emphasizing antimony-free standards for solar glass, with Germany's latest PV manufacturing guidelines and the EU's Ecolabel directive setting new environmental boundaries for imported and locally produced panels.

Homerun's technical partners advise that the Company will produce solar glass that is 100% free of added antimony from the initiation of production. Equipment and furnace design are already prepared, with the same or less CAPEX required. Operational adjustments are minor and within the existing specifications and should result in reduced OPEX since antimony substitutes are less costly. This is only possible because of the exceptionally low oxidizable iron ions levels, below 20ppm, of the Company's HPQ silica sand in Santa Maria Eterna, Belmonte, Bahia, Brazil.

Bans and restrictions on antimony use in solar glass are increasing global demand for high-purity, low-iron silica sand as glassmakers shift to safer, more sustainable feedstocks that can deliver the required optical clarity and durability without chemical additives. As antimony-free manufacturing becomes the industry standard, only silica sand with extremely low iron content is suitable for premium solar glass. This should add demand and add increased value in the marketplace for these scarce low iron feedstocks.
