Prospecting & Detecting
Determining the Amount of Gold in Rich Ores
February 2016 by Chris Ralph
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.
A Few Pointers About Cracks and Crevices
Because these crevices catch and hold gold so well, it's worthwhile to learn how they form, which ones are good for catching gold and which ones are not.
Detecting at the Sixteen to One Mine
A while back I was given a very special opportunity to take my metal detector to one of the most famous gold mines in all of California, the Original Sixteen to One mine in Alleghany.
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.
Prospecting for Liberated Gold
Some will doubt its value given the ultra-fine particle size… Some will become encouraged about not having to incur significant time and expense to break rock.
Revisiting the Rocker Box
The first location we worked was a small, dry ravine cutting through many mineralized zones in an area where some hard rock mining had taken place in the past.
Critical Minerals: Titanium
The metal is expensive, not because it is rare but because of the expense to produce and work it. The minerals mined for titanium are all oxides, unlike many base metals that are mostly mined as sulfide minerals.
Sniping for Gold
Sniping for gold… what does it mean to you? To me, sniping is taking a mask and snorkel along with a screwdriver and squeeze bottle to search for gold lying on or in bedrock.
