Margin of safety?

Am a big fan of Seth Klarman's margin of safety book, and since MGX has near its market cap in cash I think it possibly fits this analysis. I am just trying to work out a few worst case scenior's and how stock price would fare in these situations, such as the sea wall collapsing and or the iron ore price going back to 2004 levels of $10-$15, is it possible that MGX would stop mining in this situation and cut their losses at say 150million? what do you guys think would happen in these situations and can you think of any other potentially negative situations? I know some people will say IO can't go back to those levels because of inflation but here's a chart of the wheat price which last year was at the same price as it was 30 years ago
