Vancouver, British Columbia--(Newsfile Corp. - May 6, 2025) - Homerun Resources Inc. (TSXV: HMR) (OTCQB: HMRFF) ("Homerun" or the "Company") is pleased to announce that the Company has sent >99.99% Si02 samples purified previously through lab testing with NREL (US Dept of Energy), using traditional calcination and leaching techniques, to UC Davis for further purification using the femtosecond laser. On June 19^th, 2024 Homerun announced the successful production of 99.999% Si02 using femtosecond thermal laser purification of raw silica sand from the Company's Belmonte Silica Resource in Bahia, Brazil. UC Davis will now start the laser purification process with Homerun's already purified silica sand from NREL to test whether the laser purification can achieve even higher purity levels.

As Dorfner Anzaplan GmbH continues to develop final calcination and leaching test work, process design and the CAPEX estimate for our initial 120,000 tonnes per year silica processing plant in Belmonte, Homerun would like to make it clear to shareholders that the advanced purification work completed by UC Davis will be complimentary to the planned production of the Homerun Ultra-Pure Silica Sand with less than 100 ppm of impurities. Higher silica content and lower impurities correlate directly with higher market prices.

Since the origin of the Company's high purity silica plan, Homerun has worked to achieve the highest levels of silica purity for both known industrial uses and emerging markets like battery anode materials. According to ICCSINO, the global output of anode materials in 2024 was 2.1673 million tons, a year-on-year increase of 23%, of which China's anode material share further increased to 98.5 %. In terms of sales volume.

Homerun is also working with UC Davis to process the Company's Silica Sand to Silicon and Silicon Carbide. Silicon currently represents a small, but growing percentage of the Li-ion anode market. Production capacity of silicon anode materials is estimated to be less than 2% of the total anode market, by weight. While silicon's potential for high energy density and faster charging is significant, graphite remains the dominant anode material. The silicon anode market is experiencing rapid growth, with projections exceeding $15 billion by 2035, according to a report by IDTechEx.

UC Davis Partnership

Homerun and Bahia Graphite Corp. have an investment commitment to the research and development partnership with the University of California at Davis (UC-Davis). The UC-Davis Material Science and Engineering's materials research and development is conducted in the laboratories headed by Prof. Subhash Risbud. Prof. Risbud and his students are mandated to utilize their extensive expertise to continue to pioneer disruptive processing methods and advanced materials product development for the silica and graphite provided by Homerun and Bahia Graphite. The focus is on scaling production where all commercial outcomes will target zero waste and zero emissions as all industrial streams are integrated into commercial advanced materials and industrial outputs.

NREL (US Dept of Energy) Partnership

Homerun and NREL are conducting their partnership under a co-operative research and development agreement (CRADA) with the United States Department of Energy's National Renewable Energy Laboratory (NREL). NREL has completed the following works under the current CRADA:

• Developed thermal cycle testing plan;
• Screened purification methods by thermal and thermochemical processes;
• Measured Homerun sand particle size distributions;
• Measured Homerun sand heat capacity;
• Measured Homerun sand acid utilization;

The Parties are now actively working within the partnership to develop commercialization strategies for the Enduring Energy Storage System.

Executive Director Appointment - Welcoming Stephen Burega

Homerun is also pleased to announce the appointment of Stephen Burega as a new Executive Director. With more than 30 years of leadership experience across the finance, mining, communications, and public affairs sectors, Stephen brings a proven track record of strategic execution and organizational growth.
