A few rough calculations as to total value:
1 ton=2000 lbs; so 4%Cu=80lbs/t; Cu@~$3/lb=$240 income/t
Mining costs=~$60/t.
Profit=~$180/t.
AU is trading at ~$1100/oz. III has a grade of 8.83 g/t=0.311469 oz/t=$342 income/t. Profit=$342/t (We already paid the $60 to get the ore out of the ground above!).
Let's add 'em up:
Au=$342/t
Cu=$180/t
$$=$522/t
Drill hole is ~152 Meters.
Lets say the cross section when delineated by further drilling is 100M X 100M (a wild ass guess!) then over a 1000 M length of strike (another WAG!) we have 100X100X1000=10,000,000 cubic Meters of ore and that converts at ~2000kg/cubic meter weight of copper ore to 20,000,000,000kg of ore and that =~22,000,000 tons which at a profit of $522/t=~$11.5Billion total value.
With a mine life of 20 years makes the profits= ~$0.575 Billion/year=~$575Million/year.
