How To Find Gold
Get to know the characteristics of the various ores. No two gold ores are the same, but ores in the same general areas may be similar. Look for iron stained quartz. The more oxidized or rust colored the better. The more porous or vuggy the better. High grade gold ore often has an almost melted sponge like appearance.
