More on Gold Prospecting: Sulphides and Gold

Sulphide ores can contain gold in various forms, including those that are "free-milling" and the harder-to-process refractory types of ores and ore bodies. As small-scale or recreational gold miners we are most likely to spot and exploit "free-milling" ores where the gold particles are visible to the naked eye or under slight magnification.

Three different classifications may be made in the preliminary examination of ores; first, pure quartz (very glassy or vitreous); second, no quartz (plastic and free from grit); third, a mixture of these two extremes which may be assumed to be the average as to siliciousness.
