Something to Consider When You Go Dredging
August 2002 by Dave Varabioff
I have been a gold dredger for 9 years. The first dredge I bought was a 4-inch, with a 5hp engine. It had 15 feet of suction hose, a beat up regulator, a patched air reservoir, and floats that were sun baked and cracked—what a beauty. Vaughn and Darrel sold me this dredge, and could tell that this crazy “Canuck” was excited. We talked for many hours that first day I met them, and I was eager to learn...Additional articles that might interest you...

March 2003
Two landmark golden gatherings took place in Vancouver, British Columbia near the end of January, and while they both related to the world of gold, they each had a completely different emphasis.

Mud Men: Pocket Miners of Southwest Oregon Part III
April 2011
The amount of gold in the traces from the low-grade scattered veinlets may be much more than the traces from the small but rich pocket, at least until the pocket hunter closes in on the rich pocket. Further confusion arises if the prospector stumbles across a placer deposit on one of the higher peaks.

A Guide to Overlooked Gold Deposits—Part III
November 2003
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.

Synclinal Oil
April 2005
Most oilfields are found in anticlinal faults, or stratigraphic traps. Oil floats on water, so that it will rise to the highest point possible, above the water. If the porous or fractured sandstone or limestone that contains the oil is overlain by impervious shale, the oil can no longer rise. If the porous bed is arched upward...
