The rate of recovery of gold and silver from the leach pad is a significant area of estimation. Whilst inventory is shown as a current asset it is probable that some portion of the gold and silver on the leach pad will be recovered more than a year from the balance sheet date, depending on the length of the leaching cycle and on management's strategy for optimizing the recovery from the leach pad.
