Arthashastra on Mines:

Arthashastra gives detailed information on mines, minerals and metals. The way Chanakya describes each and every facet of mines, minerals and metals, proves that the Indians were concerned in this regard even in that age. In the treatise, Chanakya asserts that “Mines are the very source from which springs all temporal power for the strength of government and the earth, whose ornament is the treasury, which is acquired by means of treasury”.  Chanakya’s Arthashastra is a promising guide to change each and every passing moment of life.
