Gold Hog - Sluice Mat
What started as a study focused on riffles quickly turned into something else. We ended up looking at the ENTIRE sluice box and the role of each component. After watching literally hundreds of hours of recorded video and testing, something became VERY clear. The “riffle” played a role in the sluice box, but its role had been given TOO MUCH focus as well as a mischaracterization.
We came to the ABSOLUTE conclusion that the RIFFLE does NOT
hold gold. The riffle creates a break in flow and a low pressure zone, what
we call a LOW CURRENT zone. This low current zone allows material to build
up based on the vortex that the riffle creates. However, you will notice
that the material is sitting on the MATTING, not on the riffle. Therefore
we removed the phrase “riffles holding gold” from our conclusions and
verbiage. The riffle creates a DISTURBANCE of the lower level of the MIX.
This lower level now must go over the riffle and HOPEFULLY settle back down
when it hits the vortex. This DOES happen to an extent, but we did find
issues with “launching” of heavies and gold from the lower levels to the mid
to upper levels of the mix.
Also, vortexes during a normal run can and do break down often releasing the “stored material” behind the riffle. It now becomes the matting’s job to hold the gold. This is where our UR matting does a great job. The hidden sub-chambers give a place for gold to hide, out of the vortex pattern and all currents. It remains ACTIVE regardless of the flows direction. (which varies with vortex impact zone) A flow may be forward, down the sluice, backwards, up the sluice, or straight down from the back edge of the vortex. In each case the UR mat gave resting and hiding places that passive mats do not have. (Miner’s moss and carpet)
It was VERY clear that most passive mats rely on water flow
and current “blow out” to clean themselves. They create little to no active
reduction on their own. Hence the design of the Gold Hog™ UR mat. It quickly
cleans yet does so in an active reduction manner, retaining the heavier
