Gold Hog Recovery Rates

Gold Hog Recovery Rates and Testing

OK… Here’s a question that gets asked quite often. “What is the recovery rate of the mat?”
Man, did you just open a can of worms…
With ALL the variables and configurations that currently exist in the “mining world” it is IMPOSSIBLE to test them all. So, here is our answer.

The Gold Hog UR mat will outperform ANY passive matting or active matting on the market today when used in most high volume dredges, highbankers, or other sluice box set ups.  This is how and why it was designed.  It was designed to SELF CLEAN quickly, exposing more material to more matting surface during its travel down your sluice box.  It was designed to offer both large and small gold protective areas (low pressure zones) with little to no disturbance even under VERY high water flows. “It’s kind of like putting “bedrock” on the bottom of your sluice.” is how one person described it.  

With this in mind, the mat offers more material more exposure to holding areas, and hence greater gold recovery rates under REAL WORKING CONDITIONS.

Previous tests…

Why don’t we do comparisons like former tests did?  We did, and found our UR mat performed as good or better under these conditions. However, these tests were often limited… running “clean gravel”, limited amounts, lower water flows, or not enough material.  We felt that many of these tests were not close enough to “real life” run conditions.  (The tests weren’t tough enough.)  

Next variable…
What type of riffles?  Was the test run with riffles or expanded metal? What were the riffle setups? What happens when someone runs the same matting under a different setup? Hence our LONG and exhaustive comparison runs on HUNDREDS of riffle styles and expanded metal sizes.  Again, in ALL cases our mats performed better than any passive matting under higher water flows to even extreme water flows.

Remember, our mats were designed to perform LONG TERM under high volume conditions. Testing “recovery rates” or “loss rates” under these conditions is near to impossible.  To make a CLAIM of 99% recovery rates would not only be an assumption, it would be false.  If you WERE going to make these claims, and have them be TRULY accurate, one would have to “pan out” ALL THE MATERIAL that ran through the testing period, and not just a sampling.

Therefore and as an example, if we ran a “consumer test” we would run 150, 5 gallon buckets through a highbanker.  To truly judge losses and recovery rates, one would have to sit and PAN out  ALL the material that came off of the sluice.  Sorry, not going to happen.

“Salting the material” would not give an accurate test either.  Running LARGE amounts of heavy mineral bearing material would add non-known gold to the recovery amounts.   

This is where one needs to make the connective assumption of lower variables. 

1) Our mat is designed to handle more, higher, faster water flow than any other passive mat.

2) Our mat was designed to hold BOTH small gold and large gold under these conditions. Something passive mats are not designed to do.

3) Material, running down the sluice, under these conditions are exposed to MORE matting SURFACE during the run due to higher clean rates and exchange rates.

4) Our matting was designed to “kick off” lighter waste material such as light sands, clay, etc, that often filled up passive matting.

Number 4 is VERY important when it comes to REAL LIFE running and tests.  You can NOT claim recovery rates without also running natural materials through that would exist in normal conditions.  Clay, sands, mica, black sand, and other material that WILL easily have an impact on passive mattings’ long term effectiveness on recovery.  These materials GREATLY impact passive mats such as miner’s moss, which quickly fills up even with these lighter materials.

Large Scale Testing:
Most of the commercial operations that tested our mattings found they had increased recovery rates.  Most of these operations were using the standard setup of riffles, expanded metal, and miner’s moss.  Most saw a 10 – 20% increase in recovery rates when replacing the miner’s moss with the Gold Hog UR mat.  A couple of these operations also placed a section of the Wild Boar scrubber mat high in the recovery sluice.  They found significant amounts of gold in this matting as well.  

In summation….

The GOLD HOG™ UR mat performs better under real life conditions than any other passive mat. That claim we can make. Adding the Gold Hog ™ Wild Boar Scrubber mat is a better alternative higher in the sluice bed than riffles. It allows gold to settle and works material in a low turbulence environment.
