Homerun Resources Inc. Confirms Optimized +4N Purification Plant Pathway and Advances CAPEX Configurations for the SME High-Purity Silica
Homerun confirms its silica purification pathway while advancing a capital expenditure study alongside C$15 million in bridge financing.
Homerun Resources Inc. (HMR) has confirmed that calcination, or thermal treatment, followed by acid leaching is the preferred processing pathway for its +4N silica. Dorfner Anzaplan GmbH is currently conducting process design and AACE Class 5 CAPEX development for two +4N purification plant configurations: a traditional calcination and acid leaching setup, and an acid leaching-only configuration following alternative thermal pre-treatment.
The company is also evaluating a hybrid configuration that integrates the Enduring Energy Storage system for thermal pre-treatment. This system uses silica sand for heat storage and provides grid and PV electricity storage. An exclusive global IP agreement with Alliance for Sustainable Energy LLC (NREL) covers a recently filed patent for thermal energy storage integrated with silica sand purification. This announcement follows previous updates regarding the Bankable Feasibility Study (BFS) for the solar glass plant and the completion of the 3N plant CAPEX budget.
Homerun Resources Inc. (HMR) announced progress that validates the engineering direction for its Phase 2 (+4N) purification plant, moving the project to the CAPEX estimation stage. This development aligns with the company’s stated 2026 development roadmap.
The announcement does not introduce unexpected financial metrics, new offtake contracts, or regulatory approvals, representing an incremental technical milestone. While the technical validation supports the company's vertical integration strategy, it does not immediately alter the cash burn profile or near-term liquidity position. The recent C$15M bridge financing, announced on July 8, 2026, addresses the immediate capital need.
Homerun Resources Inc. (HMR) is developing a vertically integrated, silica-powered clean energy platform in Bahia, Brazil. The company’s flagship project is the Santa Maria Eterna (SME) Silica Sand District, which contains more than 200 million tonnes of high-purity, low-iron silica sand.
The development strategy involves a three-phase purification platform. Phase 1 consists of a 350,000 tpa 3N industrial-grade silica sand plant. Phase 2 will add a +4N advanced purified silica sand plant, followed by Phase 3, which targets 5N ultra-high purity silica for semiconductors and photonics.
Additionally, Homerun Resources plans to construct a 1,000 t/d antimony-free solar glass plant, aiming to establish Latin America's first dedicated facility of its kind. The company is also developing energy solutions, including an AI-driven energy management system known as "The Hub" and silica-based thermal energy storage (TES) technology developed in collaboration with NREL.
