Prospecting & Detecting
Ask the Experts

What are the tell signs of garnet deposits?Selectable Frequency vs Multi Frequency Detectors
I like to think in terms of “conductive mass” because it is a combination of both the conductivity of the metal and the size of the target that determine how a detector sees conductivity.
My Introduction To Gold Prospecting
At the end of the day, Jerry showed me how to clean out the sluice box and then how to pan out the concentrates. As we finished panning, there it was—a little tiny smile of gold...
Sulfides and Intergrain Gold Wire Nuggets
...these nuggets have not traveled far from the lode because the golden wire lattices would have been torn apart or flattened during weathering of rock and deposition by violent stream action.
Proper Placer Sample Processing
...your sampling procedures should not be designed to catch gold your mining technique will never recover.
What Have You Got to Lose?
It’s accepted knowledge that wet methods will recover more fine gold than dry methods and processing the gravel as a whole will get more gold than only using a metal detector. The question is how much more?
Proper Spacing of Placer Sample Sites
The zone of influence of each sample must be carefully considered when deciding how far sample sites should be spaced from each other.
Chasing Float Gold—The Starry Night Wash
The sun was beginning to set, which put the light at just the right angle against the hillsides to where I believed that I spotted a very small dig and tailings pile up the hill near the top of the second wash.
