Cornish Tin & Lithium (CTL) appointed four former Imerys British Lithium senior managers on two-year contracts to speed its tin-lithium assets to production. Hanno Buys (20+ years, 70+ projects) was Head of Mining; Ben Cordier, a chartered extractive metallurgy engineer, Head of Process; Caroline Viles, Financial Controller; Gavin Palmer, Head of Project Delivery, who earlier led EPC delivery of a 2.4 billion USD low-carbon chemical plant in Louisiana. The team will first support drilling at Tregonning South, where Phase 3 drilling completed in January 2026 showed lithium mineralisation continuity over 3.27 km; CTL also found a new tin system with over 10 new tin lodes. The Vor Project covers 26 historic tin mines, with 2022-2024 drilling defining 28 high-grade targets peaking at 6.28% tin. CEO Sally Norcross-Webb said the aim is a producing-asset portfolio, prioritising Tregonning South.

Researchers in Goa, India, have converted tin recovered from waste printed circuit board solder into functional tin dioxide nanoparticles, as reported in the Journal of Nanoparticle Research. Acid leaching brings tin into solution before conversion into nanostructured SnO2. X-ray diffraction confirmed a tetragonal rutile phase and XPS showed tin almost entirely as Sn(IV). Electron microscopy revealed nearly spherical particles averaging 7.6 nm, giving a large surface fraction for photocatalysis. Under UV light, the material removed 100% of Rhodamine B in 165 minutes and cut chemical oxygen demand by 95.2%, indicating near-mineralisation; kinetics were pseudo-first-order with a rate constant of 0.0114 per minute. Efficiency stayed at 91.96% after five cycles.

The most-traded SHFE tin contract closed up 0.69% today at 379,980 yuan/mt, with an intraday range of 374,580-384,000 yuan/mt and a turnover of 53.1 billion yuan. According to SMM's latest weekly data released last Friday (October 16), China's tin ingot social inventory fell to 7,770 mt, with a single-week destocking of 980 mt, and warehouses in all three locations pulled back simultaneously. SHFE tin warrants continued to decline to around 3,280 mt, leaving exchange-deliverable supply tight. The domestic spot market remained in a premium state, with spot prices against the most-traded contract reported at a premium of 2,000 yuan/mt in mid-October, significantly wider than before the holiday, and the backwardation structure in near-month contracts provided spot support to futures. Core logic: Tin ingot inventories in China and overseas are destocking in tandem to historically low ranges, compounded by slow production resumptions in Wa State, Myanmar, and disruptions from Indonesia's export policies, with the tight spot supply supporting a sustained backwardation structure. Going forward, attention should be paid to the possibility of a deepening backwardation structure on the LME.
