Speed Prospecting for Hard Rock Gold
July 2020 by Keith Bowen
An online video gave me some ideas, and with a lot of trial and error I developed a reliable method of panning free gold particles down below 35 microns quickly and easily.
Down around 10 or 12 inches I hit a large cobble that appeared to be one type of hot rock for this area. I thought bad things about the new technology until I checked the rock.
The type of mine dump that is best for metal detecting are the ones that consist of mixed sizes of rock and are located near some sort of excavation, commonly a shaft or adit. Sometimes the piles located along a trench dug by the miners can be productive as well.
Gold is a fairly widespread mineral in the Italian Alps and in the Northern Apennines. It is found both in primary mineralization and in past and recent floods.
The fact that mineral deposits can contribute specific types of heavy minerals is why the analysis of the heavy mineral concentrates in the streams of an area can be an important prospecting technique for finding undiscovered mineral deposits.
During my adventures I’ve learned a few key best practices that help me to consistently find gold nuggets with my detectors. You can apply many of these best practices to any type of prospecting. These best practices are really common sense; however, they are easy to neglect.
It is important to note that discrimination is a type of electronic filtering. The signal is analyzed, and depending on the discrimination setting, identified as either a target to be dug or a target to be ignored.
