Silex Systems (SLX) Mining Forum Americas 2026 summary

Technology and development

• Third-generation laser enrichment technology, invented in Sydney, is licensed in perpetuity to GLE; the classified technology has no IP sunset and carries a minimum 7% perpetual royalty.

• Large-scale demonstration reached technology readiness level 6 last year; full-scale commercial equipment demonstration in Wilmington is targeted in about a year, followed by engineering completion around then.

• Laser enrichment is described as more efficient than centrifuges, with higher throughput, lower operating costs and potentially half the capital cost; commercial construction is planned for Paducah, Kentucky.

• GLE is 51% owned by Silex and 49% by Cameco; Cameco has an option, exercisable through April 28, to acquire 26% from Silex at fair market value and reach 75%.

DOE tails project and market opportunity

• A 2016 DOE agreement gives GLE access to over 200,000 tons of depleted uranium tails for its first project; the material averages just above 0.3% U-235, with each cylinder logged by DOE.

• At Paducah, the planned plant would reprocess tails from ~0.3% to 0.7% assay, producing 5m lb/year of natural-grade uranium for 30 years; Cameco is GLE's sole customer under a recently signed offtake agreement.

• Natural-grade output represents 150m lb over the project life and ~$500m of revenue value at current prices; conversion value is included in the ~$30/lb AISC estimate and is worth about one-third of that cost.

• Planned initial LEU capacity of 2m SWU could generate $360m of annual revenue for 30 years at a stated $180/SWU price; capacity could expand to 10m SWU or more as Russian fuel imports into the U.S. are banned from Jan. 1, 2028.

• Further expansion could produce HALEU, up to 20% U-235, for small modular reactors; the presentation also cited potential LEU-plus demand from utilities.

Milestones and funding

• Full operating and construction license is targeted for Q1 2027; engineering completion is expected around late 2027, with FID targeted for late 2027 or early 2028.

• If approved, EPC for the first plant would take 2–3 years, with first production targeted before end-2030; full 2,000-ton and 2m-SWU production is an aspirational target for 2033–34, subject to market demand and Cameco's contracts.

• First-plant cost is estimated at ~AUD 1.3b; potential funding includes ~70% debt, including a U.S. DOE financing program, with all options under consideration and a possible IPO described as early-stage.

• Cash balance was AUD 180m, with annual cash burn of ~AUD 50m this year and next; project finance is expected to follow for the first commercial plant.

• Site clearing is underway; Wilmington includes a manufacturing facility, and GLE is arranging contract manufacturers and supply-chain capacity.
