Homerun Resources Inc. (TSXV: HMR,OTC:HMRFF) (OTCQB: HMRFF) ("Homerun" or the "Company") is pleased to provide an update on Phase 2 of its Three-Phase Integrated Purification Platform for the Santa Maria Eterna ("SME") silica sand district in Belmonte, Bahia, Brazil, following completion of the complementary leaching test work by Dorfner Anzaplan GmbH ("Anzaplan"), see News Release dated May 28, 2026.
Based on the reported test work and technical review, Homerun and Anzaplan have determined that the preferred pathway for processing to +99.99% SiO₂ (+4N) silica in the Company's planned Purification Plant is calcination (thermal treatment) followed by acid leaching of the silica feedstock produced by the 350,000 tonne per annum 99.9% SiO₂ (3N) Purification Plant (see news release dated June 8th, 2026).
Anzaplan's testing and the previous research and development conducted by the Company with the US Department of Energy (NREL/NRL) provides two potential configurations that are both expected to produce +4N silica from the planned +4N Plant for commercial sales and as a critical feedstock for Homerun's +99.999% SiO₂ (5N) Silica and Advanced Materials development. As the next step, Anzaplan will proceed with process design and AACE Class 5 CAPEX development for two +4N Purification Plant configurations:
- Traditional calcination (thermal pre-treatment) followed by acid leaching.
- Acid leaching only (after alternative thermal pre-treatment)
Homerun is simultaneously advancing an integrated CAPEX study which will utilize the Enduring Energy Storage system to thermally pre-treat the silica prior to acid leaching, in a hybrid +4N purification plant configuration. The Company's overall plan incorporates the Enduring Energy Storage system utilizing the SME silica sand as the medium of energy storage, in the form of heat as a key component of the general industrial development at Santa Maria Eterna. The Enduring Energy Storage system would provide electricity storage of both grid and PV inputs and output both industrial heat and power for the Silica Valley operations.

THE ENDURING ENERGY STORAGE SYSTEM INTEGRATION
The Enduring Energy Storage System is under an exclusive global intellectual property (IP) agreement between Homerun and Alliance for Sustainable Energy, LLC, the manager and operator of the U.S. Department of Energy's National Renewable Energy Laboratory )"NREL" which is now the National Laboratory of the Rockies "NLR"), and this IP includes the recently filed patent application covering a thermal energy storage system integrated internally with silica sand purification. The successful R&D testing with NLR thermally pre-treated Homerun's raw silica sand at 1,000°C.
The Enduring Energy Storage integration into the Silica Valley Industrial Facilities is strategically important because it creates a purification and commercial extension of the Company's Phase 1, 350,000 tonne per year 3N primary silica sand purification, enabling purified silica streams to move up the value chain while at the same time improving the power and thermal efficiency of the Silica Valley Industrial Facilities and avoiding the need to allocate capital and build traditional dedicated calcination into the purification processing.
This new Dorfner Anzaplan test specifically compared direct acid leaching without thermal pre-treatment against acid leaching after thermal pre-treatment at 1,000°C. The results support the Company's decision to proceed with processing the 3N Feedstock through a calcination plus acid leaching configuration as the preferred route for the best purification pathway for +4N silica.
The recently announced 3N Plant CAPEX is for a minimum 350,000 tonne per year primary purification plant targeting industrial grade 99.9% SiO₂ silica sand, establishing the upstream base from which higher value +4N and future 5N modules will be developed. Under Homerun's integrated model, the 3N plant is expected to provide a strong feedstock and commercial foundation for modular higher-purity processing, while the Enduring system offers integrated thermal processing and energy storage into the same high-purity silica powered value chain.
Brian Leeners, CEO of Homerun, stated: "When I first encountered the NRL Enduring System almost three years ago, it immediately presented as an opportunity to provide an integrated energy storage and silica purification strategy. Now after the combined testing with NRL and Anzaplan we have confirmed that view. Enduring calcination followed by acid leaching is the preferred pathway for achieving the +4N product at our Silica Valley Facilities. Homerun and its partners will now advance the CAPEX planning under both the traditional and Enduring-integrated configurations, which preserves operating flexibility while quantifying a potentially important capital and operating advantage. This reflects how the Homerun operating team and its partners continue to leverage strategic disruption to build an integrated value chain for silica purification into advanced materials for energy and tech."
Further updates will be provided as Homerun advances the process design, mass balance, equipment definition and CAPEX cases for the +4N Purification Plant in the Silica Valley of Belmonte, Bahia, Brazil.
