It may be a temporary low but demand exceeded supply for the 2nd year running last year and looks like 2012 will have a shortfall as well.
When prices plummet the mines shut down. It takes some time to get them back up to full production again. Indonesia is the main supplier and capped exports late last year although I believe they have loosened up on that now.
2010 hammered many commodities. But check out a graph of the tin price. It fell 50% and certainly has a long way to go to get back over 50,000 a tonne again.
But SOLDER is tins saviour. No tin - no solder. Solder is a must for technology consumer items and electronics.
Do a google search on tin +stocks +lme and also tin investing news.
