Scout,
You are correct, last quarters sales did not include the gold pyrite. If the value of the ore milled in Q2 includes the gold pyrite, the sales value should be $18.03/tonne higher which makes it $103.90/tonne sales.
Also the payment rate varies depending on the product. For the gold dore which goes straight to a refinery, we probably get about 96% of contained metal. For the lead and zinc concentrates we probably get a little less than 90%, and for the gold pyrite concentrate we probably get about 65%
