I went to the Daintree today for work. We went to the beach while we were waiting for materials to arrive. On the beach there was a lot of different coloured quartz rocks, some yellow, pinkish, white with black infusion and some snow white. Some stones were tumbled smooth and some more like they were crushed. The beach has a number of freshwater creeks feeding onto it. Is Quartz an indicator of gold on it's own or should there be some indication of past discoveries? Thanks, Rick
