The Jenkins Mine Project, Conclusion—Recovery Operations & Summary
This project taught me that you don’t need to be Albert Einstein to apply a little science to your prospecting. I learned that most of the science related to suction dredging is actually common sense. All we need to do is take the time to apply it.
Spanish Gold Ledge Still Producing Gold
The Gold Eye placer claims, located in the La Cholla district of Arizona, are still producing some beautiful gold. From the days of the Spanish explorers and Mexican miners, men have tunneled into the earth in search of gold in this area.

There were nice sections of vein material at the end of several drifts, like they just stopped work one day and walked away.
Exploring Placers with Auger Drills
Augers can be used effectively for placer exploration with certain limitations.
