Peru Case
Peru Case History - 2000
These four pictures were taken in Peru. There, the Beep Mat responded to a gossan hidden under 3 meters of alluvion. The gossan occurs over a horizon of sulfides. Fresh sulfides begin 50 meters below the surface.
The Beep Mat was carried 60 cm above the ground by two men. Where the Beep Mat responded, in order to reach the gossan, we dug pits through the superficial sand and talus. Then, samples were taken to assay the gossan for precious metal. By collecting cuttings from a hand-held percussion drill, we were able to collect samples 5 meters below the top of the gossan.
GDD suggests this low-cost approach to discover and sample near-surface gossans for precious metals.

To initialize the Beep Mat raise it high in the air. | |
Carrying the Beep Mat above the ground increases the penetration. | The Beep Mat beeps ! A conductor has been localized. |
