Your math is off. 55,375t of stacked ore, at 2% copper = 1,107.5t of contained copper, 80% recovery = 886t of copper potentially recovered * copper price (US$8150/t today) = US$7.2M of revenue. BUT a key variable is the timing it takes to leach copper - lets say it's a 90 day residence time for the copper to leach (and for simplicity, a linear leach curve) that means that each day the ore is on the pad gets you another 0.889% of copper recovery up to 80% (again, overly simplified). Therefore ore placed on the heap at the beginning of the quarter has been 80% recovered, but ore placed 1 month in only has 53% of its copper recovered, with 26% left to go for the next quarter, and so on. This is how heap leaches work.
Once the operation is steady state this doesn't matter so much, but at the beginning of the operation this ramp up time for the leach matters quite a bit. So for this first quarter estimate 40% recovery _from the leach_ for the quarter, or lets say 443t of contained copper. The reported heap leach recovery will take this leach curve into account, so that's why they are still reporting 80% (i.e. the copper in solution matches what they would expect based on their met test curve, therefore validating their recovery assumptions).
Since they only have 30.9t of copper produced from the sulfate plant (they aren't producing cathode), this suggests the sulfate plant commissioning isn't going well (to say the least).
