Prospecting & Detecting
Critical Minerals: Titanium
July 2018 by Chris Ralph
The metal is expensive, not because it is rare but because of the expense to produce and work it.

Gold in the San Francisco District Oatman, Mohave County, Arizona
I suspect detailed geological mapping and prospecting would lead to discovery of one or more overlooked gold deposits in the district even though it has been heavily prospected in the past.
Fault Zones and Prospects
As we walked back we were just reaching the point of where the faulting should be and there, covered with deep grass, was very faint evidence of an old road going up the mountainside! What was that old road doing there?
