Ore Reserve Estimation Method

Ore-reserve estimates include the determination of 1 tonnages of ore and 2 average grade or value per ton. Since the grade or content of valuable metal establishes the difference between rock that may and may not be classed as ore tonnage cannot be estimated without considering the question of grade. Consideration of grade in connection ...
