As SR was kind enough to send me the DB analysis I feel I should respond. The difference between my spreadsheet and DB is that they assume a decrease in production costs with volume,I kept it at a constant percentage. It will probably fall but I'm not sure it will be as large as they say. Maybe I'm wrong.Also DB do not put much share price value on the exploration rights,maybe they're wrong. So it looks a good company but I don't see their available cash being enough to purchase the volume of output to justify the present share price. I won't go further as it's outside my personal risk/reward criteria and I don't want to set off a lot of flack on this civilised thread. For all holders I hope I'm wrong. Good luck.
