Prospecting & Detecting
Geobotany: Plants Associated With Mineral Deposits
November 2014 by Alex Dolbeare
Science has shown, over the past few centuries, that there is a direct correlation between certain plants and their geophysical surroundings.
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.
To Foam or Not to Foam
George was considering filling his dredge floats with closed-cell foam, ensuring that there would be no area available within each float for flooding.
A Day On The Yuba River
There weren’t as many pieces of gold, but what I did find was bigger. As I worked my way down towards the spot that I had been working the first three days, I noticed a large crack that crossed the river.
Prepping Your Gold Detecting Spots
All bedrock cracks that appear to be wide and deep should be cleaned out completely, and if you cannot clean it out thoroughly then you should break the bedrock apart…
Selecting A Low-Risk Region To Explore, Mine or Invest
“The evidence is clear—mineral deposits alone are not enough to attract precious commodity investment dollars...”
Lessons Learned From Geologists
Not long after this, I was camped out with the geologist beside the Similkameen River where he showed me the evidence that an ancient channel existed on our claim.
Determining the Amount of Gold in Rich Ores
This is just the type of specimen that could have been easily ignored by the old-time miners. It felt a little heavier in my hand than a chunk of quartz of that size ought to have been.
