100,000 tonnes per year @ 3 grams per ton 300,000 grams or about 10,000 ounces
About $3,000 per ounce atm so gives a total available of $30mil per year.
Capture 70% at gekko plant and 25% at tailing treatment = 95% for a gross $28.5mil per year if everything works. ( I watch a lot of gold mining shows and old machines break down often)
What we don't know is the costs of the two gold processes.
