May 27, 2009· The second reson that a gold mine has to control the grade is that the milling process is usually designed to be most efficient at a certain grade. When mining a high grade zone, some of the gold may be lost and end up in the tailings unless the high grade ore is blended with low grade material, to provide the mill with a grade that it can handle.

The essence of ore grade reconciliation is to identify, analyse and manage variance between planned and actual results in a way that highlights opportunities. A consistent record of poor reconciliation is an indication that this variance has not been adequately managed. This would inevitably result in significant economic impact on mining companies.

Initial ore grade control was based on blast hole samples collected in two stages by an “automatic” sample collection device (sometimes called a rocket sampler). A sample was collected for the top 3 m (10 ft) in a holes and then the bag was changed so that a sample was collected for the lower 3 m (10 ft). Each of these samples was prepared and assayed by fire assay to determine the grade.
