Ann: Copper Projects Update - Peru, page-8

any geologist able to comment on the possible resource we may be sitting on?

from my calculations 1200 x 500 x 350 (assumed depth based on the drill hole depth provided, over 400m seems low grade) = 210 million tonnes
specific gravity of 4.5 (copper is around 9 and moly higher), but since grades of copper equivalent itself it around 3-6% I would assume 4.5 for specific gravity.

so 210 million x 4.5 = 945 million tonnes x 3% average grade (we do have as high as 6%, but looks like averaging 3%) = 28.35 million tonnes equivalent of copper? or at current prices and recovery of say 80% about - $181 billion of value in ground.

disclaimer - I am just doing a rough calculation and by no means an expert, just estimating what we may have, any experts care to check the numbers above.
