More Tips for Evaluating Ores
July 2007 by Charles L. Butler
Tabling and jigging are two relatively inexpensive methods for recovering the “free particle values” from the noble metal ores. However, not all ores contain their values as free particles. In fact, many ores contain appreciable amounts of “metallic salts” that readily dissolve in one’s system water and continue to migrate right along with this water.Additional articles that might interest you...

Alluvial Fans
April 2002
Alluvial fans are essentially dry land “deltas” which can be found in all climates. However, they are best developed in arid and semi-arid regions, where they may be many square miles in area. They are built up by outpourings of silt, sand, and gravel caused by seasonal run-off, as well as by boulders and cobbles carried by flash floods.

Connecting With The Past With Gold Rush Coins
September 2023The Keystone Gold-Copper District, Medicine Bow Mountains, Southeastern Wyoming
May 2002
The Keystone district includes a group of mineralized shear zones and veins that are associated with the Keystone Quartz Diorite in the Medicine Bow Mountains of southwestern Wyoming. Gold production from this district is unknown, although some estimates suggest that 7,500 to more than 12,000 ounces were produced.
