Q: How do I improve my small-scale mining operation’s gold production?
by Chris Ralph
Detectors: Past, Present and Future
Detectors were invented long before I was born, but it was in the 1960s when they started to become an item popular enough to power a fledgling industry. The key development was miniature transistor technology replacing the old fashioned tube technology of the 1950s, making lightweight, affordable detectors possible.

The Heavy Minerals in Your Concentrates
The fact that mineral deposits can contribute specific types of heavy minerals is why the analysis of the heavy mineral concentrates in the streams of an area can be an important prospecting technique for finding undiscovered mineral deposits.

MMAC & PLP Update
Each separate Mining District is a federally recognized entity. There are huge advantages—picture yourself going to an oversight meeting where 2, 3, 4, or even more Mining District representatives have obtained voting positions on the board.

Pocket Gold
Once a seam is found it can be traced for miles in either direction. While you are tracing a clay line, you are looking for indicators. The indicators that I look for are ironstone, hematite, different color clays intermingled with the clay line, and a very iron-rich, brown gritty soil.

Critical Metals: Antimony
I’ve been taking a look at the mining and uses of a number of critical metals in series of articles, and it’s time to take a look at antimony.

Care and Lubrication of a Model 13 Laboratory Wilfley Table
A Wilfley table works best when all of the mineral being run across it (the pulp) is about the same size.  For this reason, I took a good look at each of the samples.

Mining Districts: A Short Review of Legal Authorities
Mining Districts are the private regulatory authority granted by Congress recognized to regulate the mineral lands held by the United States and for the disposal to citizens of the United States, by means of development and potentially perfected by patent.
by Clark Pearson
Melman on Gold & Silver
Another area of growing international concern for business and industry is the recent astonishing proliferation of new government regulations and laws. Despite the presumably good intentions behind these measures it is now becoming apparent that they are imposing true costs  to our economic society. The sheer variety  of these laws and regulations is mind-boggling.

Think You Got It All? Guess Again!
Is your gold recovery actually 95%, 90%, or even a really poor 50%? If you are not testing to know what it really is, you just don’t know. Some do regular testing, but most do not.

Nevada's Silver City Gold District -- Part II
...this district has had a continuous life of gold mining and milling that spans 150 plus years, and it appears that it will keep pressing on for many more years of production.
by Alex Dolbeare
MMAC & PLP Update
PLP had been attempting to raise funds to hire a lobbyist. The excessive cost made it prohibitive, so Clark and Joe packed up their bags and headed off to make this trip themselves.

Hard Rock Prospecting With Rusty
As we talked, Rusty stopped, backed up, bent down and began chipping at some rock in the road. He said he suspected there was a stringer right here that crossed the road.

Another Successful Gold Prospecting and Mining Summit
Chad Lewis of Sacramento got into a good bedrock seam on Monday and was pulling out small chunks of bedrock with embedded gold from he lower pit. Mark Dayton of El Dorado was about ten yards away on the same line, but his spot had some visible quartz mixed in.
by Scott Harn
Drywashing in Black Canyon, Arizona
After the hike and a quick snack break we gathered a few buckets of material to really dial in the drywasher for the most efficient recovery. This involves leveling the unit, setting the riffle box drop angle and regulating the speed in which the material is processed.

Melman on Gold & Silver
In terms of gold and silver, if this mountain of unbacked debt, now reaching several trillions of dollars, Euros, Yen or other currencies begins to truly collapse into an inflationary spiral, we will witness the onset of the mother of all precious metals bull markets.

How to Stake Your Own Mining Claims—Part II
I’d like to offer some practical comments about staking and maintaining mining claims. Owning your own claim is the dream of many prospectors. I’ve made good money off my mining claims, both from the minerals I have found on them as well as from leasing out some of my claims to larger mining and exploration companies.
by Chris Ralph
Dry Washer, Wet System or Metal Detector?
I love to dry wash old nugget patches found by detector operators, and I have found my fair share of gold dry washing those areas. I have also found a few nuggets using a detector on the bedrock exposed by dry washing the patches.
by Jeff Snyder
Multiple Use Lands, Symbiotic Relations and Conflict Resolution
The automatic discrimination and exclusion of man from nature, like his access and use of the land, presupposes man as a destructive force for change, absent a relative hard look at the natural forces of change. Setting aside lands for non-use does not encourage wise use symbiotic tenets, which man has traditionally formed in his coexistence with nature.
by Clark Pearson
Enrichment of Mineral Deposits by Weathering—Part II
While both zinc and lead deposits also are enriched by the surface weathering process, in part two we will look at the enrichment process for copper and also gold deposits, and at the interpretation of leached outcrops to figure how rich the concentrated deposits below them may be.
by Chris Ralph
MMAC & PLP Update

The Tombstone Silver-Lead District, Arizona
In 1877, a prospector named Ed Schieffelin discovered silver in “the middle of nowhere” and staked two claims: “Tumbstone” and “Graveyard.” Soon a town and mining district were organized and acquired the name “Tombstone” after making a spelling correction.

Sold: 87-Ounce Nugget
A gold prospector in central Victoria, Australia stumbled across an 87-ounce gold nugget in early February 2015, after his wife told him to head outside to get some air. He had given up smoking a few weeks prior and was getting a bit “grumpy,” she told him.

Melman on Gold & Silver
...the much more important question is this: does this short-term strong rally necessarily portent a genuine turnaround from the metals share bear market that has been ongoing since mid-2011? For a possible answer, we turn to the long-term, five-year XAU chart.

Addressing EPA Overreach: What Dredgers Need to Know
The Environmental Protection Agency (EPA) has been attempting to extend their authority and intimidate miners and other public land users for decades. Suction gold dredgers are no exception, and we want to highlight a recent example of how to deal with this federal overreach.

by Scott Harn
Green Valley Gold District, Payson, Arizona
Most gold-bearing quartz veins found in the district were fracture fillings in faults enclosed by crushed quartz zones along their margins. Since the host rocks were often extensively weathered, portions of the veins stood out as positive, resistant outcrops. The gold-bearing veins ranged from a few inches wide to the vein at the Gowan mine that was as much as 12 feet wide. 

by W. Dan Hausel
Nevada's Silver City Gold District—Part I
The name Silver City is quite ironic as it doesn’t really fit the area’s metal production. The area encompassing the Silver City district is a great, stand-alone gold district, where the production value of gold has been much more than that of silver. Since the initial discovery of gold-bearing veins in the mid-1850s, the area has been a center of continuous small and large-scale gold production.

by Alex Dolbeare
Enrichment of Mineral Deposits by Weathering—Part I
The exact minerals formed in the concentrated supergene deposits depends much on the type of country rock around the deposit and the chemistry of the deposit itself, but if conditions are right, this process will form some rich patches of bonanza ore, in some places valued at thousands of dollars to the ton.

Alaska: Kodiak Islands Mineral Resources
The fresh material is worked and concentrated by the waves on the flat, wide beach platform. The waves wash away the lighter minerals, leaving the heavies near the bluffs and in depressions on the beach.

MMAC & PLP Update
Just prior to our press deadline, we learned that a bill had been introduced in the Idaho House of Representatives to redefine suction gold dredging as a preferred use in public waterways in Idaho.

by Scott Harn
Melman on Gold & Silver
...we may now be witnessing the onset of a major turn toward a period when precious metals investments outperform conventional markets as the Dow and S&P 500 now appear to be turning toward the downside at the same time when gold and silver are showing signs of rallying.

Gold in Quartz
Because quartz and gold may be deposited together across a considerable range of temperatures, not all quartz veins are the same, and there are several different types of gold-quartz deposits.
