Cut-off grade estimation -

Stockpiling is the storage of unprocessed ore, which can be sent to the mill for processing at a later time. Typical scenarios when stockpiling is utilised are when an abundance of high grade material is mined early in the mine life, or when lower grade material is mined and it would be more financially beneficial to sell the low grade material at a later time when the sale price of the
