How to Make a Rock Sled for Dredging
August 2017 by Ron Kliewer
When my “anonymous” friend told me the rock tub was probably a hundred miles from where he safely stashed it, I decided to build another sled and improve on my old design.
Once I have established the presence of gold in the sample, I collect five-gallon bucket quantities of the rock material for processing back at my shop.
Oleophilic means "affinity to or attracted to oils," and this includes gold an diamonds.
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.
Depending on the ore and if significant sulfides are present, a hard rock miner may be able to get away with simply using a flux to digest the other minerals that may be present.
Gold and jade are actually only minor mineral resources for the Northwestern Alaska region as a whole. Modern prospecting has focused more on base metal than precious metal resources.
The fact that mineral deposits can contribute specific types of heavy minerals is why the analysis of the heavy mineral concentrates in the streams of an area can be an important prospecting technique for finding undiscovered mineral deposits.
We panned out maybe three gold pans of the material and we were shocked at the gold that was there. This rock appeared to be rich.
