Mineralized Faults and Contacts in the Search for Gold

When I was a student in the College of Mines at the University of Utah, the Verde district was used as an exploration model for “submarine volcanogenic massive sulfide deposits.” So I looked forward to visiting this district and the town of Jerome in central Arizona in the spring of 2012.
This was one of those stories where you have no doubt that the person telling it believes it to be true. But was it?
Every time we prospected here we found gold, sometimes some really coarse flakes, but no large nuggets (yet).
While both zinc and lead deposits also are enriched by the surface weathering process, in part two we will look at the enrichment process for copper and also gold deposits, and at the interpretation of leached outcrops to figure how rich the concentrated deposits below them may be.
For a time uranium was more popular with prospectors than gold, but this is no longer true, and it has been decades since it was common to see individuals armed with Geiger counters out in the field.
I couldn’t wait to get started. With no field budget, an assay budget of $100/year, a 1975-Ford Bronco that was a road hazard, a gas card, a topo map and full support of the director, I headed to the State Line district near Tie Siding along US Highway 287 to begin mapping kimberlite.
