Many ores that contain gold contain other metallic metals in them also, so there are likely to be a lot of shiny minerals mixed into the rock which may or may not be valuable. The other challenge in visual inspecting gold ores for possible gold content is the fact that the total concentration of gold in a piece of ore is generally negligible.
Before you stake a claim on a spot where you''ve found a possible gold mine, take a mineral sample to an assayer. Assayers analyze the entire metallurgical content of the rock, which can help you determine whether to file a gold claim on the location. Keep in mind that many rocks contain gold – just not enough to cover the cost of extracting it.
