Homerun confirms silica sand meets solar-glass specs

Executive Summary

• Homerun Resources Inc. received a lab-scale treatment test report from Minerali Industriali Engineering Srl (MIE) confirming that its Santa Maria Eterna silica sand is suitable for the manufacture of antimony-free solar glass.
• The testing serves as a key third-party deliverable for the company's continuing bankable feasibility study.
• Results indicate the raw material has extremely high initial purity (99.7% SiO2, 24 ppm Fe), requiring minimal processing upgrades to meet solar glass manufacturing specifications.

Key Details

• Testing Provider: Minerali Industriali Engineering Srl (MIE).
• Material Source: Santa Maria Eterna, Belmonte, Bahia, Brazil.
• Raw Material Quality:
  • Purity: 99.7% SiO2.
  • Iron (Fe) content: 24 parts per million (ppm).
  • Characterized as having an inherent low-contaminant nature.
• Mineral Resource Estimate (NI 43-101 Compliant):
  • Measured: 25.56 million tonnes (Mt).
  • Inferred: 38.35 million tonnes (Mt).
  • Grade: High-purity silica sand (>99.6% SiO2).
  • Note: This estimate covers only one of the three assets controlled by Homerun in the district.
• Processing Test Results:
  • Basic Solution (Wet Screening): Reduced residual contaminants to desired ranges; Iron reduced to 14 ppm. One contaminant (Titanium/Ti) was slightly above the desired range.
  • Complete Solution (Attrition washing, grain size classification, gravimetric separation, magnetic separation):
    • Achieved 100% compliance on the first stage.
    • Iron (Fe) reduced to 8 ppm.
    • All other contaminants well below acceptable ranges.
• Conclusion: Very simple silica sand processing techniques meet or exceed required specifications for antimony-free solar glass.

Notable Quotes

• "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," — Armando Farhate, Chief Operating Officer.
