Ann: Mining of First Ore Block at Granville Tin Project, page-234

Below is from a couple of articles on Metal Bulletin. It's interesting that they note that participants are looking to China's tin supply but now their tin supply is looking shaky too. The price rise on tin has legs.

"The three-month tin price increased by more than 1% over the afternoon, making its most significant approach toward $22,000 per tonne since January 2018. Prompting the metal’s strong performance of late – typified in an incremental rise of more than 15% since its 2018-low of $18,145 per tonne on November 27 – continued delays to exports from Indonesia, the world’s second largest tin producer, remain price supportive. In addition, the LME’s depleting inventory, which sits at just over 1,300 tonnes on-warrant has prompted tin participants to seek alternative supply, with the International Tin Association estimating as much as 30,000 tonnes of material sitting off-warrant in China"

"Market participants pointed to a possible tighter tin concentrate supply outlook from China after Yinman Mining was suspended and alongside lower tin ore production in Myanmar. The Emergency Management Agency of West Ujimqin Town, Inner Mongolia, ordered Yinman Mining Industry to suspend operations on Sunday February 24 following a security incident, Yinman parent company Xingye Mining Industry Co said. The security incident resulted in 21 deaths and 29 injuries when a commuter truck that transports Yinman miners underground lost control, crashing into the subservient tunnel, Xingye Mining said on Monday. The cause of the incident is still under investigation, according to the company."
