Introduction
Background, Objective and Method
The development of mining industry in the world is in the fast growing pace as mineral commodity continue to gain good price and high demand continue to come from the fast growing new economic centers like China and India. The two factors contributed to expansion of mining industries into areas not yet entitled to any concession. This has also brought resurgence of existing concessions that are not yet developed due to uneconomic price and financial institutions’ reluctance to finance projects that would yield only small revenues.
