If it has free-milling gold you will be able to pan it out if you crush the rock to a powder first. Did you find it in a gold-producing area?
Also maybe we should consider writing a sticky thread for this forum with the basic information that people usually come to this site looking for. Not that it's a bad thing, I got hooked on T-Net after coming around asking how to see if there was gold in my black sand (there was not ), just might help a lot of people get answers more quickly and avoid redundant threads.
