Green Valley Gold District, Payson, Arizona
March 2016
Most gold-bearing quartz veins found in the district were fracture fillings in faults enclosed by crushed quartz zones along their margins. Since the host rocks were often extensively weathered, portions of the veins stood out as positive, resistant outcrops. The gold-bearing veins ranged from a few inches wide to the vein at the Gowan mine that was as much as 12 feet wide.

February 2004
Geology books are best used by geologists, but many of the old-time books can be understood by most anyone who has an interest in rocks and minerals.

Some of the old-time mining geology books should be in every small miner’s collection.

The Silver Islet Mountains of Utah
January 2014
I set up my dry washer on the north side of the cut and sampled the bed rock and dumps around me. As I was only sampling, I ran for 20-30 minutes, shoveling from a variety of areas.
