Gold Ore. High-grade gold ore from a quartz vein near Alma, Colorado. The appearance is typical of very good gold-quartz ore. Metal ores are generally oxides, sulfides and silicates of “native” metals (such as native copper) that are not commonly concentrated in the Earth’s crust. Ore bodies are formed by a variety of geological processes.

Gold vein stockwork in limonite from Colorado, USA. (public display, Denver Museum of Nature & Science, Denver, Colorado) The Colorado rock shown above, nicknamed “Tom’s Baby”, is an extremely high-grade gold ore. It was found in 1887 at Farncomb Hill, Colorado
Also consider that gold concentrations in ore is never consistent, often occurring in pockets rather than consistently throughout. So a mine that produces some high-grade ore will also process tons of ore with almost no value. To the naked eye, these ores may look exactly the same.
