Feasibility studies for mining projects – AMC

Scoping StudiesPre-Feasibility StudiesFinal Feasibility StudiesA scoping study may be carried out very early in the exploration phase, as a basis for acquiring exploration areas or making a commitment for exploration funding. At this stage the investment risk may be relatively small but it is obviously undesirable to expend further funds on something that has no chance of being economic.The major risk is that a viable mining project is relinquished due to an inadequate assessment. As there is a very low probability of an exploration project proceeding to...
