Average grade (H35) = available contained gold (H30 + H31) / available ore mined (H24 + H25) The stockpile calculations are a critical component of a mining financial model. Modelling stockpiles is a crucial component of a financial model in a mining project, because most likely mining companies are not able to mill all the ore that they mine.

Using a gold wash plant, exposed gold-bearing gravels are mined using a bulldozer that pushes and stockpiles the gravel near a wash plant.The stockpiled gold-bearing gravel is then fed into the wash plant by a front-end loader or large backhoe. This practice promotes equipment efficiency by allowing the bulldozer to continue mining while the loader or backhoe feeds the wash plant at a steady rate.

Initial ore processing commenced in early February 2019 using low-grade stockpiles. The mill employs a conventional gold circuit comprising crushing, grinding, gravity separation and cyanide leaching with a carbon-in-leach circuit, followed by cyanide destruction and filtration of the tailings for dry stacking.
Both transported and residual laterites, up to 15 m thick, host gold mineralisation, which typically averages gold grades of 0.5 to 2.0 g/t, over extensive lateral areas. Saprolite mineralisation tends to be of higher gold grade (1.5 to 5.0 g/t), but is generally developed over more restricted zones 2 …
