Oct 01, 2010 Traditional methods for ore tonnage and average grade estimation in a single ore deposit can be roughly classified as either geometric or geostatistical Henley, 2000. In exploration, both of these methods utilize the orebody thickness and the grade over a given thickness e.g., in drillholes or drifts located in a grid to estimate the reserve.Online Chat
These methods include panning, sluicing, hydraulic mining, and dredging. Draglines were used to mine some placers. Cut-off grades are also dependent on the value of gold during the period, or periods, of operation. Some placer deposits were excluded due to grade or tonnage figures not compatible with the majority of placers found in the model.Online Chat
