Proper Spacing of Placer Sample Sites
September 2013
The zone of influence of each sample must be carefully considered when deciding how far sample sites should be spaced from each other.

Underground in the Original 16-1 Mine
August 2013
These days they employ the use of metal detectors and carefully scan the shattered rocks, hoping to hear that sound we detectorists love to hear.

Romancing the Rock
July 2013
With the exception of well-established operators with proven reserves and years of field experience, the high price of gold brought a flood of speculators, con men, and real estate brokers into the mix who were not previously engaged in the gold mining market.

Placer Channel Sampling
July 2013
Sampling gold placers can be rewarding, but remember to treat the samples so you are not high grading or low grading your results. Learn the rules and apply them so your samples are accurate.

Gold Rush in the Congo—Part II
June 2013
We needed something to cook on, so we brought most of our kitchen with us including our full-size oven, which was pretty funny to see in the middle of a rainforest. Food was always a concern, but fortunately for us...

Spanish Gold Ledge Still Producing Gold
June 2013
The Gold Eye placer claims, located in the La Cholla district of Arizona, are still producing some beautiful gold. From the days of the Spanish explorers and Mexican miners, men have tunneled into the earth in search of gold in this area.

Gold Rush in the Congo
May 2013
It all started with a phone call from my friend and prospecting partner Pat Keene. He told me that he knew of an investor who was just starting out in the gold industry and was looking for a gold consultant to go to Africa to prospect and analyze a 400 sq. mile concession in the middle of the Congo rainforest. I waited for the “just kidding” line...

Excavator Testing Wet Placer Ground
April 2013
The excavator or backhoe has become the tool of choice for testing placer ground. These machines are the best way to explore and sample a placer deposit if the ground is not too wet or frozen and bedrock is not beyond the reach of the machine.

Hard Rock Milling: A Matter of Scale
April 2013
Most prospectors understand placer mining a lot better than hard rock mining and don’t realize the amount of work that goes into processing different types of hard rock ore.

Selenium, Mercury and Suction Dredging—Studies Contradict CA State Water Resources Board
April 2013
Federal and state regulatory agencies often cite mercury and methyl mercury in our waterways as a major factor for further restrictions on placer mining, and on suction gold dredge mining, in particular. However, these regulatory agencies are minimizing selenium and its neutralizing effects.

Gold Deposits of Montana
March 2013
Historically, Montana has been an important gold producer, in terms of both lodes and placers, and it still produces gold for the prospector today.
Refractory Gold Processing
February 2013
After your excitement peaks when you first receive the high gold assay from the vein you just exposed, you ponder how you will extract and sell your gold. You will need to develop a flow sheet for your process to optimize your recovery and minimize your costs and permit requirements.

Extracting & Smelting Your Gold
February 2013
Unfortunately, not all the gold that we prospectors find is pretty, or appealing to the eyes. They are not all nice, bright, shiny nuggets with lots of character that carry high collector value.

Customizing Your Dredge
January 2013
I am going to suggest dozens of ways you can increase suction power, dredge to greater depths, and improve recovery methods in your sluice box.

Scams, Scammers and Schemes
December 2012
Gold mining has received many black eyes from many scams, scammers and schemes throughout the years. Unscrupulous scammers have swindled naive people for millions of dollars in the past and will, no doubt, continue into the future.

Gold Dredging on Oregon's South Umpqua
November 2012
Familiarizing oneself with an unfamiliar part of the country is often a requirement of successful gold prospecting. In the pursuit of gold, it may become necessary for a prospector to branch out into new hunting grounds.

Proper Assaying of Placer Samples
November 2012
The whole purpose of sampling mineralized ground is to measure the values in a small volume of material that would be representative of a much larger volume of similar material. The key word is representative. Chemical and fire assaying will not accurately represent placer deposits by themselves.

Dredging Backwards?
October 2012
Before I tell you what dredging backwards is, I’ll tell you why my team and I decided to give this very unconventional dredging method a try.
