ASP Isotopes (NASDAQ: ASPI) has completed construction of its Silicon-28 enrichment facility in Pretoria, South Africa, and begun commissioning phase. The facility's annual capacity is now expected to exceed 50 kilograms of Silicon-28 enriched to 99.995%, up from previous guidance of 10 kilograms. The company has secured two purchase agreements with US-based customers and anticipates first commercial deliveries in 1H 2025. The facility processes silane directly, potentially offering higher quality product without additional chemical conversion. The plant operates under International Atomic Energy Agency oversight, and the company plans to expand with additional facilities in Iceland and the United States.
