These deposits were estimated to contain over 400 million ounces of gold; however, only 2 pct of this amount was found to be exploitable at $35 per ounce. A 400-pct increase in the price of gold within a period of 1 or 2 years caused a remarkable reevaluation of the type of material that constitutes ore.

Gold usually occurs in these ores as discrete particulates (<0.1 µm in diameter) within sulfide minerals (mainly in pyrite and arsenopyrite) (Hausen, 1981; Radtke, 1985; Hausen et al., 1986; Wang et al., 1992, 1994). In gold ores, pyrite and arsenopyrite often occur in three morphological types: coarse, porous (blastic) and fine-grained.
