kilotonnes. For an exponentially smoothed stockpile, the average "age" of the ore is 1/a1 kiloton-nes. So to emulate a stockpile size of T kilotonnes we should use a smoothing constant a1 per kilotonne, where: α1 = 2/Q (4) Thus, for a CSMS to be equivalent to a stockpile size of 200 kilotonne, α1 should be 0.01 per kilotonne.
