Cornish Metals has completed front-end engineering design (FEED) for the process plant at its South Crofty tin project as it ramps surface and underground activity.
The mineral exploration and development company advancing the wholly owned and permitted South Crofty project in Cornwall says the tin price near US$53,000/tonne lifts the project's NPV6% to roughly £500m at current spot prices.
"Dewatering is underway through the fully commissioned 195-level pump station for the first time in over 28 years," CEO Don Turvey said.
Surface work at Roskear is progressing with the winder house structure and cladding in place and civil works at Roskear and NCK shaft underway to support planned winder mechanical installation in the second half of 2026.
A new workshop and stores building is nearing completion, the New Cook’s Kitchen offices are operational, and excavation for the pre-concentration building is about 50% complete.
Underground, development at the 25-level continues and pre-production development at the 290-level is now expected to start in Q4 2026 with an underground drilling programme to follow shortly after.
Dewatering is on track toward the 400-level (about 730m below surface) in H1 2027, detailed engineering continues under Ausenco and Optimult, and orders for long-lead items including shaking tables, skips and cages are being placed.
