HOMERUN RESOURCES INC. ADVANCES PHASE 2 OF ITS THREE-PHASE PURIFICATION PLATFORM DORFNER ANZAPLAN COMMISSIONED FOR COMPLEMENTARY LEACHING TEST WORK ROUTE CONFIRMATION AND CAPEX DEVELOPMENT FOR THE SME HIGH-PURITY (+4N) SILICA PURIFICATION PLANT

Homerun Resources Inc. has advanced to the final pre-CAPEX phase of its ambitious three-phase silica purification platform, commissioning Dorfner Anzaplan GmbH to perform complementary chemical leaching test work on samples from the Santa Maria Eterna deposit in Belmonte, Bahia, Brazil. This Phase 2 development targets production of +99.99% SiO₂ (+4N) and +99.999% SiO₂ (5N) purity grades, building directly on exceptional metallurgical results announced in December 2024 that demonstrated industry-leading purification capabilities.

The previous Anzaplan program validated multiple purification routes, reducing total impurities from 306 ppm to as low as 74 ppm and achieving iron levels as low as 0.89 ppm - exceeding specifications for Type I optical glass. The starting material quality of 99.694% SiO₂ with exceptionally low aluminum content provides a distinct competitive advantage, as aluminum is among the most difficult impurities to remove from silica. These results confirmed applications across high-value markets including solar glass, optical glass, fused silica, and silicon carbide.

The additional test work represents a strategic optimization rather than remediation, targeting a simplified process route that could meaningfully improve operating economics before locking in the final plant design. Upon completion, Anzaplan will deliver a comprehensive CAPEX package including process design, block flow diagrams, mass balance, major equipment specifications, and AACE Class 5 capital cost estimates for the approximately 30,000 tpy Phase 2 facility.

Homerun's integrated approach advances all three phases concurrently: Phase 1 (350,000 tpy industrial grade), Phase 2 (advanced purified), and Phase 3 (ultra-high purity for semiconductors and AI infrastructure). The company reports active engagement with finance parties throughout the development process, positioning the project for potential funding decisions upon CAPEX completion. This systematic approach to high-purity silica development addresses growing demand across the energy transition value chain, from solar glass manufacturing to advanced semiconductor applications.
