Fortunately, there are several clues that most folks seek. The most underrated gold clue is the presence of mica in places where you can find gold. You can find gold together with several metal indicators, including mica and quartz. In fact, at the Canadian Malartic, Gold mineralization is associated with white mica potassic and Microline-biotite.
