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.
When you approach a location, even if you've been there before, you should consider all the factors and conditions present at the site. This includes both natural and man-made factors.
...if you have a good, rich spot, hand-operated systems can produce some decent gold.
I love to dry wash old nugget patches found by detector operators, and I have found my fair share of gold dry washing those areas. I have also found a few nuggets using a detector on the bedrock exposed by dry washing the patches.
When doing your initial armchair research and selecting potential areas to explore, consider all the indicators, both natural and man-made.
Kimberlite is very difficult for geologists to find, let alone prospectors and rock hounds. This is because kimberlite is rarely exposed on the surface and few people know how to identify the rock.
Once I have established the presence of gold in the sample, I collect five-gallon bucket quantities of the rock material for processing back at my shop.
So far this year we have recovered over three pounds of gold and the hard rock veins seem to go on forever. We now have three claims that can produce good enough gold to set up a productive operation.
