I know it was stated at onetime MXSG could produce for $400/ounce
While I doubt that is still their estimate I also doubt that the MXSG will have "all in sustaining COST" WOULD BE $1000"
Remember that the Julio vein has sections that assy out at greater than 5 ounces per ton that would greatly reduce all in costs. That is Bonanza grades
Many of the mines that have an all in cost of $1000/ounce are working with very poor grades / ounce when compared to MXSG grades / ounce that could be the biggest factor in the "all in cost" equation
