March 2015 by Bruce Mann
Once I have established the presence of gold in the sample, I collect five-gallon bucket quantities of the rock material for processing back at my shop.

Northwestern Alaska Mineral Resources

The Heavy Minerals in Your Concentrates
June 2016
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.

The Oregon Claim
December 2010

The Jenkins Mine Project, Conclusion—Recovery Operations & Summary
November 2010
This project taught me that you don’t need to be Albert Einstein to apply a little science to your prospecting. I learned that most of the science related to suction dredging is actually common sense. All we need to do is take the time to apply it.

Wyoming's Billion Dollar Nugget—The Trilogy Ends
August 2011
Our testing over the past 15 years was to confirm or deny the USGS report completed in 1978. Besides the half acre test dig, we completed many additional test digs by hand and with the backhoe.
