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.
In some ways, silver is the forgotten precious metal because it straddles both the world of precious metals and jewelry, while having many important industrial applications like a base metal. The price of silver reflects both the precious metal investment demand as well as the industrial demand.
For the prospector, knowing what oxidized hydrothermal alteration looks like in the field is an important exploration tool.
