    MINERAL ORE RESERVE Case 1 When all holes have positive values, let a, b and c, be the depth of ore in the three holes forming the prism; to find the average depth of the ore influenced by any given hole, use the formula: d = 4a + b + c/6 Then,An "ore deposit" is a mineral deposit which has high enough grades of metal that makes it economic to mine Essentially this means that per tonne of rock containing the desired minerals, the costs of removing the minerals from the rock and separating the metal from the minerals are lower than the value of metal per tonne of rockGeology: What is a Mineral Deposit? — Mining Focus
