Same here, none of us expected this and most of us are really disappointed.
Tin will be very important in next 10-20 years and car manufacturers will need more of it so there is good future for Tin. I still like the project and will be really happy when in production . KAS is extremely cheap now. 127,000t of Tin (could be more) in the ground x $21,000USD = USD$2.6Bil
