Hi Jonnyash They are funny numbers. 10,000t over 1/4 = 111t/day. (10,000 ÷ 90 days) The stockpile is supposed to be 4g/t (we are waiting for that announcement) ... transporting 1000t/day is more likely but lets be conservative and say CAI transports 600t/day of 4g/t ore to the mill. The mill processes 300t/hour. 22 hours @ 0.85g/t = 170 ozs/day (22 x 300 x .85 ÷ 33) 2 hours @ 4g/t = 72.5 ozs/day (2 x 300 x 4 ÷ 33) = 242.5 ozs per day production = 88,500 ozs per year production. The additional high grade blended into the feed supplies an extra 26,400 ozs of gold. CAI's share of that is 15,850 ozs (60%) which at current spot prices adds $46,750,000 straight to the bottom line.

Nice calcs but how does a 1.5g/t stockpile over double to 4g/t. That’s weird?
