Homerun Resources Inc. Announces Positive Results of Confirmation Testing by Minerali Industriali Engineering on the Santa Maria Eterna Silica Sand for the Manufacture of Antimony-Free Solar Glass

KEY HIGHLIGHTS:

• MIE has successfully completed testing, confirming suitability of Santa Maria Eterna silica sand for high quality, antimony-free glass manufacturing.
• Initial material quality is extremely high allowing for minimal upgrades to achieve the technical requirements for solar glass manufacturing.

Homerun Resources Inc. (TSXV: HMR,OTC:HMRFF) (OTCQB: HMRFF) (‘Homerun’ or the ‘Company’) is pleased to announce that the Company has received a Lab Scale Treatment Test Report from Minerali Industriali Engineering Srl (‘MIE’ and MIE Report) (see press release from November 18th, 2025) of the high purity, low iron silica sand from Santa Maria Eterna, Belmonte, Bahia, Brazil, confirming its application for the manufacture of antimony-free solar glass. This work is a key third-party deliverable under the Company’s ongoing Bankable Feasibility Study.

As previously announced, Homerun has completed a 43-101 compliant Technical Report with Mineral Resource Estimate containing a preliminary resource of 25.56 Mt Measured and 38.35Mt Inferred of high-purity silica sand (>99.6% SiO2). This Mineral Resource Estimate is from only one of the three assets controlled by Homerun in the District.

The MIE Report starts with a characterization of the unwashed raw silica sand, which confirms the inherent low-contaminant nature of this unique material, with purity of 99.7% and only 24ppm of Iron/Fe.

Two sets of tests are conducted: (1) the basic solution, consisting of wet screening; and (2) the complete solution, consisting of attrition washing and grain size classification, gravimetric separation and magnetic separation. XRF analysis was performed on all treatment outputs:

1. The basic solution showed a reduction of almost all residual contaminants within the desired range (Iron/Fe was reduced to 14 ppm), and only one contaminant was slightly above the desired range (Titanium/Ti).
2. The complete solution test showed 100% compliance on the first stage (attrition washing and screening), with Iron/Fe reduced to 8ppm and all other contaminants well below acceptable ranges.

These results are encouraging, confirming that very simple silica sand processing techniques meet or exceed the required specifications.

‘These results confirm our initial expectations, that mother nature has performed most of the work needed to make the Santa Maria Eterna silica sand a very unique material, giving Homerun an important competitive edge in the production of antimony-free solar glass,’ stated Armando Farhate, COO of Homerun.
