en.Wedoany.com Reported - Cornish Metals is advancing underground development at the South Crofty tin mine project in Cornwall, UK, with ongoing shaft refurbishment and dewatering activities.

Underground operations are progressing in multiple directions, including shaft refurbishment and ongoing design work. At the New Cook's Kitchen shaft, dewatering activities are proceeding as planned, targeting the 400 level approximately 730 meters below surface by the first half of 2027. The shaft refurbishment includes removing headgears, installing scaffolding and work platforms, and preparing infrastructure to support production and service hoists.

On the engineering front, front-end engineering design for the loading, unloading, and hoisting system is underway, undertaken by Optimult. Development of the 25 level, extending from the Tuckingmill decline approximately 45 meters underground, is progressing alongside staff training. This area is used to meet rock handling and skip discharge infrastructure requirements and to develop workforce skills ahead of anticipated production.

Early refurbishment has begun at the Roskear shaft, located 850 meters west of the NCK shaft, including scaffolding installation and headgear removal, with its planned use as a primary ventilation shaft and secondary emergency exit. Surface civil and engineering activities continue, with updates emphasizing underground progress. Pre-production development of the 290 level is expected to begin in Q4 2026, followed by an underground drilling program.

Long-lead items such as skips and cages for the NCK shaft have been ordered. Cornish Metals CEO Don Turvey stated that strong progress continues across multiple work streams at South Crofty, with the new NCK office on surface now operational and the workshop and warehouse building nearing completion. Construction of the Roskear hoist room is progressing well, early shaft refurbishment has begun, and the completion of front-end engineering design for the process plant marks a significant step.

Tin prices of approximately $53,000 per ton support the project's economic outlook, with an estimated net present value of around £500 million ($669.35 million) at current market prices.
