of widespread use, such as iron ore and limestone, exploration more than replaces the stock of resources consumed through mining. A case in point is Australia whose iron ore resources have increased a hundred fold in 40 years through a process of increased exploration and beneficiation, as cited in the Hoda Committee Report 2006.

The actual extraction of limestone is made by separating the rock in quarry ledges and dividing it into blocks. Here is an overview of Vetter's Stones extraction process: On one exposed side, a 50-foot horizontal hole is drilled at the base of the ledge where limestone will be extracted. Another 50-foot hole is drilled every eight to ten feet.

Abstract Limestone is a fundamental raw material in various industrial sectors. It is formed due to biochemical precipitation of calcium carbonate, and further com-paction over long periods of time. A high market for limestone products and its use in a growing number of industries has led to its widespread exploration and exca-vation.
