You tell me the quantity of copper and silver used as a flux, and then price that in. You tell me the amount of energy consumed in this process and its cost.
Show me where they were able to recover and re-use the copper and silver used in this process.
If you don't have an assay technique how do you know where or what to mine? If you can't recover or produce gold in the met. test or pilot plant (or its costs more than the value of the gold recovered) how are you going to pay for this operation?
