March 2000 by Carolyn DobbsWithout a telephone, electricity, or television in his isolated cabin, Olson led a simple and peaceful life. He enjoyed living in a remote canyon surrounded by a vast wilderness. Mining for gold absorbed his days.
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.
The Interior Department is proposing a moratorium on new mining and grazing in a 176-square-mile area of central Arizona dotted with American Indian ruins, a possible first step toward a new national monument.
PLP is also concluding its funding and review of a scientific study which names the suction dredge as the preeminent tool for reclaiming American waterways to counter atmospheric mercury impacts coming from China.
The placer deposits of Utah occur in two distinct types of environments. These are 1) placers found adjacent to, and derived from, gold, silver and base-metal deposits; and 2) placers found in major rivers and derived from unknown, distant sources.
A Wilfley table works best when all of the mineral being run across it (the pulp) is about the same size. For this reason, I took a good look at each of the samples.
Most of the old large gold dredging operations used a trommel. The trommel consisted of a long metal cylinder made of heavy punch plate in which the small gravel, black sands, and gold would fall though holes and end up in banks of sluices.
Ditches almost always started in the high country and contoured the mountainsides, making a long drop, usually many miles away, to the goldfields. There are ditches in Trinity County that originate at seven and eight thousand feet in the Trinity Alps that carried water almost thirty miles.
