I began the experiments aged 14 which resulted in invention some years later. I was attempting to find a way to recover micron gold from Michigan sands and gravels. They are prevalent, just like in other United States gold bearing regions. However, the problem was the gold was very fine and powdery.

Toward the end of the 1990s I became particularly focused on how to trap this fine gold.

Twelve prototypes ensued of varying configurations and finally on No.13 I had trapped all the micron gold (400 Mesh and greater) as determined by legal assay.

The only issue, which in fact turned out to be quite a substantial ancillary benefit was not only did I recover all the micron gold, I recovered every single mineral of higher density or specific gravity too. This included silver, lead, mercury, platinum, copper, chromium, molybdenum, zinc, zirconium, uranium, cobalt, vanadium, arsenic and the entire Lanthanide Series of the Periodic Table.

This represents a great moment of discovery and breakthrough for me. The invention is also highly environmentally friendly which is in keeping with my own philosophy. My invention helps “renu the Earth”.

Nusluice can also be used for remediation of coal fly ash and dredging of channels to remove industrial toxins. I have also successfully used the sluice to remove toxins in frac sand thereby improving the crush rate (or K value) for proppants used in fracking. I have cleaned Flint drinking water from “unfit for consumption” to “undetectable” after only 2 feet exposure to the sluice.

Uses in mining of all types as a second source of revenue and also to ensure that toxic minerals are removed during the handling of mining overburden.

This was the first indication that I was on to something special when this garnet became trapped in my sluice, and would not leave. I pulled it out, and later recognized it as a garnet.
