Prospecting & Detecting
Critical Minerals: Titanium—Part II
August 2018 by Chris Ralph
There are both hard rock and beach sand types of titanium deposits, but the hard rock deposits need to be at least 10 percent titanium while the beach sands often are economic with only two or three percent titanium.
Trying Out the New Highbanker
The 2011 gold season had finally got underway on the Middle Fork of the Feather River near Quincy, California. Cold weather and high water had pushed gold mining into mid-summer, but things were looking up.
Take it to Bedrock
Picking the right spot to placer has to do with years of experience, and a little luck. The textbooks can tell you where it should be, but sometimes the rules just don’t seem to apply.
What About Palladium?
Palladium may well be an underexplored element and therefore an opportunity for prospectors and geologists. This is because they are often less than obvious and other than the native metals, a chemical analysis of samples is required to identify PGM-enriched rocks.

Weathering, Erosion and Placers
The big interest to prospectors thinking about the effect of erosion is not what might happen long into the future, but what they might find in the rivers later this summer when the water levels go down.
Nevada's Lithium Boom
When prospecting for lithium, after confirming for macro attributes through research and field work, including examination of surface geology, the main tool is an accurate lithium assay.
Sampling Placer Stockpiles
Sampling other people's stockpiles or dumps has some inherent risks that sampling undisturbed ground does not have.
