Dredging Tips From The Golden Rogue
September 2011 by Jack W. PetersEveryone has a bucket list, and one of my items has always been to dredge and dive in a major river, Oregon’s Rogue, with the opportunity to find some chunky gold.
It’s not easy to figure out what is best without testing, and so a certain level of confusion has developed about how small the ore ought to be crushed.
Palladium may well be an underexplored element and therefore an opportunity for prospectors and geologists. This is because they are often less than obvious and other than the native metals, a chemical analysis of samples is required to identify PGM-enriched rocks.
There are three basic power sources for rock drills—electricity, gasoline and compressed air. Before we go into big pneumatic drills, we’ll start with a quick rundown of each.
If there is misleading wording anywhere, it will be in the sample data and in reserve/resource estimates.
A two-pronged approach is necessary to restore suction dredging; federal preemption needs to be established as addressed above via petition; and clarification from the EPA is needed to establish that no Section 402 permit is necessary when there is no “addition” of a pollutant.
These days they employ the use of metal detectors and carefully scan the shattered rocks, hoping to hear that sound we detectorists love to hear.
The favorable geology of the northeastern and central parts of the Seven Troughs Range are the parts most interesting to prospectors. They are underlain by a thick sequence of Tertiary volcanic rocks, mostly rhyolites and andesites.
