As you may or may not know i went out and spent £5.99 on a new calculator with lots of 000000000000 (think the £5.99 bit might be new information)
and this is what it told me (my old one told me error)
max 40000 m long max 3500m deep @4m wide @2.5 tonnes per meter = 1,400,000,000 tonnes @21g a tonne = 2,940,000,000,000g divide by 31.01 to get troy oz = 948,081,264 oz with in ground value of $140 per oz = $13,2731,377,000 divide by 88,000,000 shares =$1508 a share
but i will take $32 a share am i being greedy!
