Uphill Battle Continues for California Dredgers


There are currently three controlling agencies or entities over suction dredging in California—and you can make that four if the state legislature decides to further muddy the waters with additional legislation to block suction gold dredging in the state.

Understanding Skim Bar Placers


Perhaps the most notable thing about skim placers is that they form on the top surface of gravel bars, as opposed to coarser gold placers where the weight of the gold particles allows the gold to settle down on or near bedrock.

Detecting Canyon Bedrock in The Sierras


My plan was to go up the canyon along a ridge and then drop into the canyon whenever I came across a spot that might give me reasonable access.

Mining Journal Receives Honor


For the 20th consecutive year, ICMJ’s Prospecting and Mining Journal was voted “Prospecting Magazine of the Year”...

Gold Prospecting: For Better or Worse


We all love to see that first glimmer of gold when it peeks out from under the black sand in our pan, or feel the weight of a nugget in our scoop when we dig a good target. But sometimes things don’t go quite so smoothly.

Old Mine Sites and New Technology


We’ve had two trips to the deserts of Nevada and explored mines and mill sites, hiked miles of ravines in California, and swung our detector coils over thousands of square yards of bedrock.

What Happened to The Gold Prospecting and Mining Summit?


We continue to seek out a patented mining property with an owner who is willing to host such an event with a water supply and enough remaining gold to make it worthwhile for the students.

Highbanking for Gold


Pumps can be set up quite a distance away horizontally from the sluice, even hundreds of feet. It will work so long as there is sufficient water at the source where the pump is located. Vertical distance is more of a problem than horizontal distance; 30 to 40 feet is the maximum vertical climb for most pumps.

Gold Placers in Italy


Gold is a fairly widespread mineral in the Italian Alps and in the Northern Apennines. It is found both in primary mineralization and in past and recent floods.

Critical Minerals: Titanium—Part II


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.

Detector Brings New Life to An Old Lode Mine


…it was immediately evident the previous owner had not been using a detector. During just a few months of working the dumps part-time, he recovered gold in quartz specimens valued in excess of $40,000.

The Batteries Metal Rush


There is a major change coming in the economy of the world and now is the time for prospectors and miners to grab a ticket and get on board.

Blackberries and Gold


There were iron stains all over and even a few places where I could see iron trash sticking out of the bedrock. These would be ideal spots to start with as the gold travels with the iron and lead.

Mining Pegmatite Deposits


With successively lower temperatures as the water mixture cools, new sets of minerals are formed and many of those stable at a higher degree of heat became subject to alteration as the temperature progressively moved lower.

SS Central America Gives Up Millions in Gold Rush Era Gold


A treasure-seeking young man whose name will forever remain anonymous made the months-long journey either over land or by sailing ship to California after word spread about the gold strike in 1849.

PLP Update: Back to The 'Swamp' on Behalf of Small Miners


We spent the morning in a meeting with one of the higher-ups at the US Forest Service. I presented him with 412 complaints received from our readers, along with a summary of the complaints to make his job easier.

Falcon Fanatic: Journey of a Novice Detectorist


My first day using my pinpointer I detected an area where the fellas’ big guns had swooped in and cleaned up all the “big gold” and I got over sixty tiny pieces of gold.

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.

Putting Together A Small Free Gold Mill—Part II


There are many smaller old hard rock mines out there—more than you might think. There are some small hard rock properties that are even open to be claimed if one does the right amount of research to find them.
