GSTX outlines U.S., Australia and New Zealand silicon wafer supply chain plan

By AI, Created 2:46 PM UTC, June 04, 2026, /AGP/ – Graphene & Solar Technologies Limited said it is building an integrated solar materials supply chain across the U.S., Australia and New Zealand to produce high-purity quartz, polysilicon, silicon ingots and wafers. The company expects first U.S. wafer sales in the first half of 2027 as it tries to reduce solar materials dependence on Asia.

Why it matters: - GSTX is targeting a supply-chain gap in solar materials manufacturing outside Asia. - The plan aims to add domestic capacity for key inputs used by solar cell and module makers. - The company is positioning Quartz & Silicon Materials as an integrated supplier across multiple stages of the solar materials chain.

What happened: - Graphene & Solar Technologies Limited outlined an integrated solar materials strategy covering high-purity quartz, polysilicon, monocrystalline silicon ingots and silicon wafers. - The work is being carried out through Quartz & Silicon Materials Corporation subsidiary companies in the United States, Australia and New Zealand. - GSTX said the model is designed to speed commercialization, shorten time to market and build an order book. - Executive Chairman and CEO Jason May said the company is executing in a structured, methodical way across sales, engineering, planning and procurement. - GSTX said initial wafer sales are expected in the first half of 2027 from its first U.S. plant.

The details: - The company plans sequential expansion, starting with nearer-term silicon wafer manufacturing and later moving upstream into monocrystalline silicon ingots and polysilicon. - In the U.S., the QSM supply chain is designed to comply with Foreign Entity of Concern rules addressed by the One Big Beautiful Bill Act. - GSTX said its next steps depend on permitting, contracting, logistics and other factors. - The stated project steps include finalizing project readiness, confirming equipment costs and completing implementation documentation. - GSTX also plans to secure upstream supply arrangements and existing off-take agreements while pursuing additional customers. - Site selection will include evaluation, diligence, permitting and utilities planning. - Equipment procurement will be coordinated with logistics and site readiness. - The final phase calls for installation, commissioning, qualification and the start of wafer production. - QSM intends to serve a broad range of downstream solar cell and module manufacturers as an independent supplier. - GSTX said QSM has a U.S.-based entry into the solar materials industry focused on an integrated supply chain from high-purity quartz and silicon materials to silicon wafers. - GSTX is headquartered in Phoenix and trades on the OTCID Basic Market under the symbol GSTX. - More information is available at the company’s website.

Between the lines: - The staged approach suggests GSTX is trying to reduce execution risk by moving from wafers first to upstream materials later. - The geographic footprint across the U.S., Australia and New Zealand may be intended to diversify sourcing and manufacturing options. - The first U.S. plant and 2027 sales target make the plan dependent on a long development cycle, not an immediate revenue ramp. - The forward-looking language signals meaningful uncertainty around financing, permitting, contracting and market conditions.

What’s next: - GSTX will work through site selection, equipment contracts and project readiness before installation begins. - The company will need to complete commissioning and qualifications before wafer production starts. - If the schedule holds, the first U.S. wafer sales would come in the first half of 2027. - GSTX said it will continue pursuing financing plans, project development timelines and manufacturing plans subject to risk and uncertainty.
