How to Recognize Hard Rock Gold Ores. September 2017 by Chris Ralph. I regularly get inquiries along the line of Hey I found this rock and I think it might be gold ore. How can I tell Prospectors are always on the lookout for gold-bearing rocks that may be the source of any nearby placer gold.

How To Identify A Gold Bearing Area Sciencing

Apr 25 2017 Gold prospecting and identifying gold-bearing areas have become increasingly more feasible due to research developments on the geological process of gold formation. See References 1. Gold bearing areas mostly throughout the western United States have drawn and sprouted entire communities based on prospecting. .
