The Challenge

Rob Opie needed a faster feedback loop. When opening a new cut, he faced the "prospector's blind spot":

Slow Verification: Traditional #4 expanded metal and angle iron riffles took too long to clean out mid-shift.
Uncertainty: He couldn't quickly tell if he was actually "in the gold" or just moving dirt.
Potential Loss: He suspected his traditional riffle system was bypassing gold that wasn't being caught in the expanded metal.

The Solution

Rob opted for a Hybrid Sluice Setup, integrating Dream Mat® technology alongside his existing equipment:

The 20" Swap: He removed a section of #4 expanded metal and placed a 20" Dredge Mat right below the angle iron riffles.
Lunch Break Cleanouts: Designed for speed, the mat allowed him to pull "super concentrates" and pan them out in minutes.
The Scavenger Effect: The mat was positioned to catch any gold that the high-profile angle iron missed.

The Results

What started as a temporary testing tool quickly became a permanent fixture in Rob's sluice run:

Found "Invisible" Gold: The Dredge Mat caught gold that had completely bypassed the angle iron and was never visible in the expanded metal.
Reduced Downtime: By verifying his gold count during lunch, Rob could adjust his mining location immediately without waiting for a full end-of-day teardown.
Permanent Conversion: The results were so undeniable that Rob stated he "never took it out and never will."

"The Dredge Dream Mat worked so well, catching gold that the angles missed and that we never saw in the expanded metal, that we never took it out and never will... it was so fast to pull it and pan out the super concentrates."
