Homerun Resources

11/06/2026

One high-purity silica resource. Multiple pathways to value.

Over this series, we have followed Homerun’s silica journey from resource access in Bahia, Brazil, through independent validation, processing, solar glass, advanced materials, and long-duration energy storage.

Each partner plays a distinct role in that journey:

• CBPM supports Homerun’s long-term access to high-purity silica resources in Bahia.
• Dorfner Anzaplan and Minerali Industriali Engineering contribute technical validation, process development, and engineering support.
• Jundu, with Sibelco’s industrial context, represents a potential supply, extraction, and primary-processing pathway.
• SORG and Cebrace bring glass-manufacturing technology and Brazilian industry expertise to the proposed solar-glass facility.
• Sengi Solar provides a potential commercial pathway for solar glass in Brazil.
• CEITEC supports cooperation on silicon-carbide substrates and wafers for advanced materials.
• NLR collaborates with Homerun on the ENDURING thermal energy-storage system.

Together, these relationships illustrate Homerun’s vertically integrated strategy: connecting a high-purity silica resource to solar energy, advanced materials, and long-duration energy storage.

The journey starts with silica. It continues toward solutions.

Yesterday, Homerun announced the appointment of Leonardo Cunha to it's board of directors.

Regarding his appointment, Mr. Cunha stated:

"I look forward to working with the Board and management team as the Company progresses its industrial development plans and pursues strategic opportunities across the silica, solar, energy-storage and advanced-materials sectors.”

Mr. Cunha’s appointment complements Homerun’s strategy to build an integrated industrial platform anchored by its high-purity, low-iron silica resource in the Santa Maria Eterna district of Bahia, Brazil.

A new chapter for Sibelco in Brazil. A strategically important addition to Homerun’s Board.

Following Sibelco’s announcement that it has completed the separation of its Jundu joint venture, Homerun welcomes Leonardo Passos da Cunha to our Board of Directors.

Leonardo previously served on Jundu’s board representing Sibelco. His experience across Sibelco and Jundu brings a highly relevant perspective to Homerun as we advance our silica-to-solar-glass strategy in Brazil.

With Santa Maria Eterna among the operations designated to become part of Sibelco, that experience is particularly relevant: an understanding of the businesses, industrial markets and commercial priorities connected to the district where Homerun is building its future.

For Homerun, this appointment is about bringing relevant industry experience into the boardroom as we work to translate our resource position into industrial opportunity.

Welcome to the board, Leo.

The Landscape Has Shifted in Brazil’s Silica Valley

Today, Rockstone News has published a report on Homerun, examining Homerun’s progress in Santa Maria Eterna, Bahia, where the company is developing a vertically integrated platform to convert high-purity silica sand into purified silica, solar glass, and advanced materials.

In this report, 3 recent developments were highlighted:

•⁠ ⁠Homerun completed the acquisition of 442.7 hectares of land adjacent to its planned industrial site, securing space for processing, solar glass, and future expansion.
•⁠ ⁠Homerun received an AACE Class 5 CAPEX estimate for a modular scalable 4N silica purification plant targeting +99.99% SiO2
•⁠ ⁠Leonardo Cunha joined Homerun’s Board of Directors, bringing experience from leading materials and industrial minerals corporations like Sibelco and Jundu.

Welcome, Sibelco, to the Santa Maria Eterna Silica District! 🇧🇷

Homerun Resources welcomes Sibelco as it begins a new chapter in Brazil following the completion of the Jundu joint-venture separation, with Santa Maria Eterna among the sites designated to become part of Sibelco.

As a global industrial minerals company, Sibelco brings valuable expertise to a district central to Homerun’s strategy, from high-purity silica to solar glass and advanced materials.

We look forward to this next chapter for the district and the opportunities ahead for Brazil’s high-purity silica value chain.

Homerun’s silica strategy extends beyond solar and advanced materials into long-duration energy storage.

Homerun Energy USA has entered a global intellectual property agreement with Alliance for Sustainable Energy, manager and operator of the U.S. Department of Energy’s National Laboratory of the Rockies (Formerly National Renewable Energy Laboratory, NREL), covering NLR’s particle-based ENDURING thermal energy-storage technology.

The ENDURING system is designed to store renewable or off-peak electricity as heat in high-purity silica sand, with the potential to dispatch electricity and heat when needed.

Homerun’s collaboration with NLR began under a Cooperative Research and Development Agreement to evaluate integrating silica-sand refinement into the ENDURING system. It has since advanced to a global IP agreement including a patent application for a thermal energy-storage system integrated with silica purification.

This work positions Homerun’s silica as a potential foundation for long-duration energy storage, supporting greater use of renewable power.

Next, we bring the full silica-to-solutions journey together.

Beyond solar, Homerun’s silica strategy extends into advanced materials for the semiconductor economy.

Homerun has executed a three-year memorandum of understanding with CEITEC, Brazil’s state-owned semiconductor company, to cooperate on silicon carbide substrate and wafer technologies.

CEITEC brings national semiconductor expertise and a mandate to develop advanced electronic technologies in Brazil. The collaboration is intended to support the development, qualification, and eventual manufacturing of semiconductor-grade silicon carbide substrates and wafers.

For Homerun, the MOU creates a potential pathway to connect its high-purity silica resource and materials capabilities to a vertically integrated Brazilian silicon-carbide supply chain.

Next: how Homerun’s silica could support long-duration energy storage.

Earlier this week, Homerun announced that it has received the final AACE Class 5 CAPEX estimate.

But now that the CAPEX estimate is complete, what does this mean for Homerun?

Homerun’s next steps are expected to focus on:

(i) completion of the review of the pilot-scale and bulk-sample test work already undertaken,

(ii) continued customer sample qualification work following delivery of the 4N bulk sample,

(iii) selection of the preferred 4N purification plant configuration, including the determination of the role of the ENDURING TES system,

(iv) advancement of the financing approach and capital structure for the staged 3N and 4N plant development, and

(v) continued permitting and site-preparation planning to support early earthworks at Santa Maria Eterna, subject to applicable approvals.

Further updates are expected as Homerun progresses configuration selection, customer qualification, financing strategy, and the engineering steps required to advance the project toward implementation.
