HOMERUN RESOURCES INC. AND UC DAVIS PRODUCE FUSED SILICA GLASS FROM SME SILICA SAND USING FAST JOULE HEATING AND FILE PATENT APPLICATION FOR FEMTOSECOND SILICA PURIFICATION PROCESS

Homerun Resources Inc. has achieved a significant technological breakthrough in collaboration with the University of California, Davis, successfully producing fused silica glass directly from raw silica sand using a one-step thermoelectric Fast Joule Heating (FJH) process. This innovation eliminates the need for chemical reagents and multi-step conventional processing methods, potentially revolutionizing the production of high-purity fused silica materials. The process utilizes a novel tube-within-tube configuration where silica is confined to an inner tube while the outer tube contains conductive substrate, sustaining temperatures above 2000°C necessary for silica conversion.

The achievement builds upon previous validation work by Dorfner Anzaplan that confirmed SME silica sand's suitability for fused silica production using conventional methods. The FJH breakthrough addresses a critical market constraint - the limited supply and high cost of high-purity fused silica due to expensive conventional processing techniques. This technology positions Homerun to supply premium markets including semiconductor fabrication, high-performance optics, and advanced electronics applications.

The timing of this development aligns strategically with significant market developments, notably Nvidia's recent $4 billion investment in photonics companies Lumentum and Coherent to advance AI data center capabilities. Fused silica serves as a critical substrate material for photonics applications, which use light instead of electrical signals for faster, more energy-efficient data transfer in AI systems. The technology's applications span lithography lenses, wafer substrates, fiber optics, laser systems, and emerging quantum computing components.

Homerun has also filed a new patent application for a femtosecond laser ablation process that purifies silica sand to ultra-high purity levels (from 99.75% to +99.99%) without hazardous chemicals. The company's next phase involves scaling the FJH production capacity using off-the-shelf equipment, with testing already initiated. This integrated approach from raw material extraction at their Brazilian silica resource through advanced processing positions Homerun across the entire silica value chain, from basic industrial applications to cutting-edge technology markets driving the energy transition and digital transformation.
