Cornish continues refurbishment work at South Crofty
None
The most recent news, dated December 1, 2025, is an operations update for the South Crofty Tin Project. The company, Cornish Metals Inc., reports that the work program at South Crofty is progressing in line with its latest guidance.
Key operational highlights include: - NCK Mid-Shaft Pump Station Refurbishment: Expected to be completed before the end of 2025. - Mine Dewatering to Lower Pump Station: Expected by mid-2026. - Underground Development at No. 1 Level: 600 metres of development has been completed, serving as a training platform for newly recruited miners. - New Workshop and Stores Facility Completion: Targeted for the end of Q1 2026. - Mine Dry Phase 2 Completion: Targeted for Q1 2026.
Don Turvey, CEO, emphasized that activities continue to advance following the successful fundraise in Q1 2025.
This news release is an operational progress update, and its impact is assessed as Routine - Neutral. - Consistency with Previous Expectations: The timelines provided in this update, particularly for the NCK Mid-Shaft Pump Station refurbishment (expected before year-end) and mine dewatering to the lower pump station (expected mid-2026), are consistent with the guidance provided in the Q2 and Q3 2025 financial statements (August and November 2025 releases). In July 2025, the company had already revised the dewatering completion to the lower pump station from Q4 2025 to mid-2026, and this update simply reiterates that revised timeline. - Progress Metrics: The update includes specific progress metrics like 600 metres of underground development at No. 1 Level, which demonstrates tangible advancement. The targets for the New Workshop and Stores Facility and Mine Dry Phase 2 completion (Q1 2026) also show ongoing construction. - Lack of New Information: There are no new financial results, changes to project economics (like the recently updated PEA), or significant corporate developments (such as financing or strategic partnerships) announced. The CEO's statement confirms that the work is "progressing in line with our latest guidance," implying no material deviations from prior expectations. - Overall Project Timeline: The overall target for first tin production remains mid-2028, a timeline that was adjusted in July 2025 from an earlier 2027 expectation. This news does not alter that overarching timeline. - Market Reaction: Given the routine nature of the update and its alignment with previous guidance, it is unlikely to elicit a significant market reaction or materially impact the stock price beyond daily fluctuations.
Cornish Metals Inc. is a mineral exploration and development company focused on the South Crofty Tin Project in Cornwall, United Kingdom. The company's primary objective is to restart tin production at this historical, high-grade underground tin mine. If successful, South Crofty would be the only primary producer of tin in Europe or North America, positioning the company strategically in the critical minerals supply chain, as tin is essential for electronics and energy transition technologies.
The South Crofty Tin Project has existing infrastructure, including multiple shafts. The company holds permits for underground mining (valid until 2071), construction of a new processing facility, and all necessary site infrastructure. An updated Preliminary Economic Assessment (PEA) in September 2025 (filed October 2025) indicated robust economics, with an after-tax NPV6% of £180 million (US$235 million), an After-tax IRR of 20%, and a capital payback period of 3.3 years. The PEA projects average annual tin production of over 4,700 tonnes for years two through six, with All-In Sustaining Costs (AISC) under US$13,500 per tonne for the same period. The pre-production capital requirement is estimated at £198 million (US$177 million).
Current development activities at South Crofty include: - Mine dewatering and refurbishment of the New Cook's Kitchen (NCK) shaft. - Construction of surface facilities like the new workshop, stores, and mine dry. - Excavation and earthworks for the new processing plant area. - Underground development at No. 1 Level. The company aims for first tin production by mid-2028.
