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.
