Determining The Optimal Crushing Size for Gravity Recovery
It’s not easy to figure out what is best without testing, and so a certain level of confusion has developed about how small the ore ought to be crushed.
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.
Following Man-Made Ditches to Recover More Gold
Because of multiple take-out points along a ditch line, the ditches themselves become a wealth of knowledge to us present-day miners.
Sixteen to One Gold Mine: Going Underground - Pt II
We descended hunched over, down a long, steep, wooden staircase to the 1,000-level.
All About Native Silver
Some of the wire forms are strange and fantastic, with wires sticking out in twisted, seemingly random directions. Others have deformed crystals and all of them have significant value to collectors.
Internet Forum Gold
I made my way up past where I left off and the wash was going to end in about 100 feet. It was then I got a sweet signal.
Gold In The Midwest—Part II: Illinois, Indiana, and Ohio
In this article, I am going to take a look at three Midwest states and go through some of the prime places for prospectors to find nice local gold there.
21st Century American Gold Rush: Rare Earth Elements
The burning question I needed answered was why didn’t the deposit ever get mined of at least one of the valuable minerals? A couple of reasons have come to light.
Exceptions to the Rules: Re-Thinking Prospecting Rules of Thumb
Looking at the exceptions to the basic rules is sort of an advanced prospecting discussion, but the readers of ICMJs Prospecting and Mining Journal are plenty able to handle it.
Prospecting The East Fork San Gabriel Canyon, Southern California
I have found gold more than 200 feet above the river. It was not unusual for nuggets of an ounce or more to be found in these deposits, but fine gold and flakes are much more common.
Hit the Slopes to Find More Gold
Watching for these areas is one of my primary targets during the winter. It doesn’t take but a few inches of the surface moving away to give a fantastic target response that you didn’t hear prior to the washing of the surface.
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.
Back to Green Valley--With A Sluice
As I planned for my trips, I concentrated on how to lighten my pack yet still carry enough gear to make the trip productive and enjoyable.
A Lesson In Underwater Sniping
Of course, I know a bit about crevicing, but Steve seems to really have a knack for it, and I’m all about continual learning. I can always learn a few tricks from the pros.
Gold in The Midwest--Part I
Gold can potentially be found in all the glaciated areas of the Midwest, but to find it in any appreciable amount one needs to look to areas where the gold gets concentrated by more recent water flows.
Achieving Accurate Metal Detector Discrimination
Your odds of going home with gold will be higher using the discrimination mode, even if you might have misread one of the targets you rejected.
My New Passion--Crystal Hunting
I decided to dig near it to see if there were any more and immediately uncovered others. In total I found a pocket with over 100 crystals in it. I was hooked.
The Half-Mile Claim
We dug and extracted for two more hours. This time, as I dumped the concentrates, I saw a piece of gold three-fourths of an inch long and as big around as a pencil.
Montana Gold and Sapphires Revisited
I had a chance to visit the operation in person and talk with Neal. I was very impressed and I think our readers could learn a lot about building up a commercial placer operation from scratch…
Crumb Hunting With A VLF Detector
Chris got a nice target signal on the edge of rising bedrock, but still in a low, but washed area. After breaking up the bedrock, he recovered several pieces of gold amounting to almost three pennyweight.
