Vortex Drop Riffle (VDR) Rubber Mats (for sluices and highbankers)
Upgrade your sluice into a flour gold catching beast with these VDR mats by Infinity and Devin Gold. Popularized by shows like Yukon Gold these VDR mats are the gold standard for fine gold recovery. If you can get the small gold, you can definitely catch the big stuff!
Compared to mainstream mats these VDR inserts significantly increase the recovery of flour gold particles that would normally be washed away into tailings. Every dot adds up! Put every speck possible into a jar where it belongs instead of leaving it behind!
These mats are the perfect production companion to a mini sluice, allowing a prospector to recover significantly more fine gold and then process the concentrates in a simple, efficient process.
The mat inserts also fit common sluice and highbanker designs like the Keene MiniMax Power Sluice concentrator.
7x36 inch mats available upon request. ($168)
A sluice with VDR mats is best set up at approximately 8-12 degrees (8 recommended to start). The sluice should be placed on level ground and be level across its width. The vortex riffles work with varying water flow levels but they should have enough flow over the vortices to slowly displace lighter material and the black sand from gold (about an inch of water). You should adjust the angle and flow rates to match the material being processed until your tailings checks come up nearly clean.
