HOMERUN RESOURCES INC. COMPLETES DISTRICT CONTROL STRATEGY WITH PURCHASE AGREEMENT FOR 582 HECTARES OF LAND AND SURFACE RIGHTS OVER SANTA MARIA ETERNA HIGH PURITY SILICA SAND DISTRICT, IN BELMONTE, BAHIA, BRAZIL

Homerun Resources Inc. has signed a purchasing agreement over the Fazenda Conjunto Sao Jose e Nova Esperanca, located in the municipality of Belmonte, Bahia, Brazil, in the district of Santa Maria Eterna. The agreement covers a total area of 582 hectares and represents the final component of the district control strategy initiated in first quarter 2023 and secures long-life economic interests and control over the SME silica sand district, providing security of supply, scale and the location for the company's planned high-purity silica sand industrial complex.

Completing the SME district control strategy

Over the past three years, Homerun has executed a staged consolidation strategy over the SME silica sand district, starting with a stated plan but no initial position in the SME district. The company has secured mineral leases, supply agreements, surface rights and direct land ownership within the SME district. This strategy has delivered the competitive advantage of effective district-scale control of this unique high-purity silica resource which can provide decades of substantial silica sand supply for downstream industrial use.

The land being acquired under the agreement for Fazenda Conjunto Sao Jose e Nova Esperanca is directly contiguous with Homerun's 99-year, renewable surface rights over Fazenda Sao Jose, which were secured in December, 2025, specifically for the installation of the company's silica sand industrial complex, including processed silica and solar glass manufacturing. Together with Homerun's three CBPM mineral lease acquisitions and its long-term material supply agreements, this land position completes the SME district control strategy.

Brian Leeners, chief executive officer of Homerun, stated: "Just over three years ago, we were the only party to identify the globally unique value of the SME silica sand district as a critical material supply for the global solar and energy storage sectors. At that time, we set about on an ambitious plan to commercially control the SME silica sand district, an ambitious plan considering Homerun had no position in the district and minimal financial resources at that time. That original plan has manifested today into Homerun obtaining that desired control of the SME silica sand district through direct resource ownership, resource partnership and direct land ownership. Homerun's SME control is a key requirement for the execution of the next phases of the company's strategic plan -- developing and capitalizing Homerun's high-margin silica processing and antimony-free solar glass manufacturing in the SME silica sand district on the industrial site now controlled by Homerun."

The $1.1-million (U.S.) purchase price under the agreement is to be paid as follows:

• $500,000 (U.S.) by wire transfer in five equal and successive monthly instalments, the first instalment being due on June 25, 2026;
• $600,000 (U.S.) in Homerun common shares, priced at market value at the time of the agreement, which is $1 (Canadian), subject to TSX Venture Exchange approvals and the four-month statutory hold period and to repurchase and anti-dumping clauses.

The agreement also transfers the standard Brazilian mineral lease/royalty rights for mineral exploration with third parties from resources within land/surface rights areas.
