RE:RE:zinc 1.12$
actually we do produce copper but as a bulk con so we do get paid almost the market price. Obviously we get paid more once the ratios of chemicals are fine-tuned. You have complex mineralogy transitioning from supergene to primary as you have a redox change so you''re going to get unanticipated 'strange' minerals in this thin window. Once they get past this redox interface into pure primary it will be very simple to deal with.
