John--- you are absolutly right about a VAC PAC. I checked my back issues of Popular Mining--- Page 32, December 1990. "Product Test Report: VAC-PAC" by Phil Hontz of Albuguegue, New Mexico. It was manfactured by Mike Gajda in Marysville California. However "vacuum devices" were not new. Industrial type vacuum cleaners were used with varying results for many years. Sam Ege in Colton California was using a homemade unit back in the 1970's.

But as I best remember(?), units such as the VAC-PAC, and also the Mack-Pack (Peo-Mack Mining supplies) were only collectors. However, Phil was very impressed at the V-P'a suction power.

At this time-- as I remember(?) they were powered by small two-cyle gasoline engine and required an oil&gas mixture for lubrication.

John, correct me if I'm wrong but you were once involved with PESCO? A leading-edge constant air drywasher? In the design? Gosh this was years ago when the constant air
principle first became popular.

As I remember, the PESCO units were "design" efficient. If properly ran, there would be little lost in the tailings.
Actually, a surprising amount of gold can still be found by drywashing.
