How To
A Data Miner Builds A Power Sluice
October 2012 by Greg Mast
Data mining involves processing huge amounts of digital information to find hidden patterns and financial relationships. To executives, the findings are like gold, but on the weekends, I prefer seeing the real thing in the bottom of my pan.
Where Should I Start?
Digging in the right spots will produce excellent results, like this group of nuggets taken by the author while metal detecting during the last few months. The biggest nugget is over an ounce.
Evolution Of A Desert Wash Plant
The water instantly dropped though the screen, leaving a pile of mud behind! I was so excited that I replaced it with a 150-mesh screen, and the same thing happened!
Iron Minerals, Your Detector and Gold
It’s worthwhile for the prospector using a metal detector to know a little bit more about the association of iron and gold as well as how iron minerals affect your metal detector.
The Basics of Froth Flotation
I thought it might be worthwhile to take a look at the basics of this important mineral separation technique and how a miner can use it to recover the values out of an ore.
Proper Assaying of Placer Samples
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.
Making A Big Discovery
We sent them a lot of information, including my presentation about the area and its potential. We were excited to learn a couple weeks later that the company was interested in the property.
Speed Prospecting for Hard Rock Gold
An online video gave me some ideas, and with a lot of trial and error I developed a reliable method of panning free gold particles down below 35 microns quickly and easily.
