Basic Geology for the Independent Miner—Part V Geology of Hardrock Gold Deposits
May 2006 by Chris RalphIn this installment we will finish up our discussion of how primary hardrock gold deposits form. Understanding how rock alteration works can lead to some good ideas for exploring around old mining districts.
How many more clays seams lie adjacent to known shear zones and quartz veins in the pocket areas of southwestern Oregon?
Senator Richard Bryan (D-NV) is assuring gold producers in Nevada and around the world that Congress will block the Clinton administration's attempt to sell off international gold reserves to help some debt-laden poor countries.
The article that appeared in the October 2002 Issue of ICMJ, “Confessions of a Professional Nuggetshooter,” by Lunk, is an example of how to use a “deep-seeking-type” metal detector to lay down a grid pattern to “mine” eluvial placer gold after prospecting and finding the first nugget as the locus.
Tabling and jigging are two relatively inexpensive methods of recovering the “free particle values” from the noble metal ores. However, not all ores contain their values as free particles. In fact, many gold ores contain appreciable amounts of “metallic gold salts,” some of which readily dissolve in the system water and continue to migrate right along with it.
• What goes up, must come down.
“It is with great sadness that after more than 30 years in business in Pasedena, Cal-Gold will close its doors,”
- Some mining claim fees increase
- Oregon miners file appeal
- US Fish & Wildlife law enforcement policing powers restrained
