The Pearce Mineralized Area, Dragoon Mountains, Arizona—Part II


There are many prospects within the known mineralized area and along the margins of the mineralized area that should be examined for gold and silver.

The Birimian Greenstone Belts of West Africa


A few years ago I had a tremendous opportunity to visit Australia and hunt for gold there. The geology of the gold deposits there was somewhat different from what I was used to here in the US.

Eolian Gold Deposits


Prospectors who specialize in electronic detecting for nuggets in desert areas are especially interested in this type of deposit, as it yields nuggets that are close to the surface of the ground...

Heavy Sands Mining


Lately my mind has been involved with group 4 of the transition elements, namely titanium, zirconium, and hafnium. They all have similar chemical properties. Of greatest interest to economic geologists and miners is that these valuable elements often occur together in sands.
