A government push to shut down around 1,000 illegal tin mines in Bangka Belitung is being viewed by analysts as a potential catalyst for PT Timah Tbk (TINS) to lift output and bring supply back into the formal chain. Indonesian President Prabowo Subianto has estimated that informal mining may account for roughly 80% of the region's total tin output, while the Indonesian Tin Exporters Association has put illegal exports at up to 12,000 tonnes per year. Hans Kwee, co-founder of Pasar Dana, said the crackdown is a positive catalyst for TINS because ore that previously flowed to informal channels could re-enter the formal supply chain.
