How do you find a gold vein?

These might be directly under your feet, or they may be in nearby hills or cliffs. If your prospecting site is near a gold-rich river or stream, keep in mind that gold is heavy and may have eroded out of the banks or any nearby high places. Look for quartz in the rock veins you’ve found.
