So gold ore is not necessarily gold colored, but rather it can looks like any other rock that you might encounter. The exception to this would be truly high-grade gold ore that has actual gold veins running through it. This type of gold is exceedingly rare. People almost NEVER find it picking up the random rock off of the ground.

The above pre-treatment stages can be changed based on ore mineralogy. For a complex Au–Ag ore, direct cyanide leaching resulted in only about 47% and 19% extraction of gold and silver even after very fine grinding at <38 µm.Diagnostic leaching was carried out to assess the nature of refractoriness [29].Depending on the results of the diagnostic test results, extraction strategies …

This type of argillitization followed the emplacement of the volcanic and volcaniclastic rocks and may be called as "autohydrothermal" with no direct effect on the ensuing gold ore mineralization (Table 1).
