How To
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.
Hard Rock 101: Mechanical Techniques
Since we know that the secret to breaking rock is applying force from the inside out (putting tension on the rock), we will be looking at ways we can generate force using human and machine power.
Finding Gold with a VLF Detector—Part II
It is this ability to hear and respond to the faintest of audio signals that I believe separates the best nugget hunters from everyone else.
Some Tips and Tricks for Dredgers: Determining Pulley Size and Belt Length
If Epd is larger, then the compressor will be spinning faster than the manufacturer’s maximum specified RPM and might destroy itself. If this happens, then the compressor again might not produce enough air to support a diver. Neither is a desired outcome.

Pocket Gold
Once a seam is found it can be traced for miles in either direction. While you are tracing a clay line, you are looking for indicators. The indicators that I look for are ironstone, hematite, different color clays intermingled with the clay line, and a very iron-rich, brown gritty soil.
Prospecting for Liberated Gold
Some will doubt its value given the ultra-fine particle size… Some will become encouraged about not having to incur significant time and expense to break rock.
