Cornish Metals plc (LSE:TIN) has reported progress at its South Crofty project, pushing mine dewatering past a depth of 400 meters. The mining company has completed the setup of its service winder and has started installing the production winder. In addition, bulk excavation work for the processing plant is now largely finished, while recent drilling confirmed tin mineralization west of the current resource estimate along with high-grade tungsten. Shares of the company were trading up 0.48 percent at 104.5 GBX following the update.

The underground progress and site preparation mark a shift from initial setup to active construction. Reaching deeper levels through steady mine dewatering is essential to gain physical access to underground ore bodies. Installing hoisting machinery and preparing the processing plant site set up the core infrastructure necessary to support future production capacity and mine development.

Looking ahead, the company aims to reach the 400-level target in the first half of 2027. Key upcoming catalysts include meeting further dewatering and shaft refurbishment targets, awarding plant construction contracts, and delivering updates to the mineral resource estimate and operational timelines.
