If you read page 2 of the ann, there is one metre of 19.55 ounces per tonne.
A tonne of that ore, with a probable SG of 2.3 - 2.6 would be approximately .4 to .5 of a cubic metre.
Work that a little further, a cubic metre of that lot is worth around $50k.
Not bad.
Wish I had some more cash.........
