Alteration: Quartz-sericite-pyrite. Ore control: Economic gold mineralization occurs within two felsite (rhyolite) breccia pipes. Gold occurs as fine, rounded inclusions inside of coarse, euhedral pyrite or in contact with pyrite as fracture fillings or along grain boundaries (Corbett, 1980, cited in Sharp, 1984, pg. 138).

It is not unusual for a beginner to wonder about the difference between gold and the other materials found inside of a streambed or lode deposit. Sometimes a beginner will puzzle over shiny rocks; and quite often, iron pyrites (fool's gold) or mica are mistaken for the real thing. In fact, this is so much the case that there is a story of an entire shipload of iron pyrites having been shipped over to England from America during the 1500's, the yellow stuff having been mistaken for gold.
