A Word from the Editor

I've received a few letters over the past year regarding assays and assayers. Most wanted to know how to tell the good ones from the bad. You'll find most of these questions answered by Ralph Pray in his article, "Fake Assays and Assayers," in this month's issue.

Green Valley Gold District, Payson, Arizona
March 2016

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.
