RE: how it works Its a story of run time and rate. Quick numbers show an average processing rate of 23,000 tpd for Q1. 89% availability for March end and compared to the budgeted 92%.
23,333 tpd @ 0.377% yields = 88 tonnes tpd Cu x 90 days x 2000 lbs = 15,833,770 lbs GROSS
Produced 13.7 mmlbs / 15.8 mmlbs = 87% Recovery - on target
35,000 tpd from the average 23,333 tpd on the quarter is 50% increase and using the above numbers yields 6.85 mmlbs/quarter totaling 20.5 mmlbs per quarter or 82.2 million per year excluding incremental recovery they achieve as the process continues.
Rough numbers, expand where you see fit.
