Want to find a lot more gold when you get out there to prospect? Well I’ve put together ten ideas that I think will help you become more successful…
Pumps can be set up quite a distance away horizontally from the sluice, even hundreds of feet. It will work so long as there is sufficient water at the source where the pump is located. Vertical distance is more of a problem than horizontal distance; 30 to 40 feet is the maximum vertical climb for most pumps.
Gold and jade are actually only minor mineral resources for the Northwestern Alaska region as a whole. Modern prospecting has focused more on base metal than precious metal resources.
So much of gold detecting depends on attention to detail. Every gold area offers its own distinct geological markers and as prospectors we must pick up on those markers.
Within this area, about two million ounces of gold and fifty million ounces of silver have been mined. Faults, dikes, veins and fissures that carry the ore form a concentric radial pattern—like spokes on a wagon wheel—around the caldera core.
