Would need to look at net assets as per Balance Sheet and divide by issued shares.
At a guess I would say 3 to 10c per share, but I am not interested in calculating !!. If you do, you can post so we all know. (pretty sure the figure has been stated...maybe look at one of the research reports where they provide an estimate of the share price.
As this value is based on cost and not future discounted cashflows, my guess is most of the share price is based on thin air. ie intangible assets not reflected on the Balance Sheet.
