Itronics announced the signing of a contract to test its Rock Kleen on heap leach and mill tailings for an operating gold mining company. While identifying potential new salable products and industrial materials, the test will also focus on possible solutions for environmental issues identified by the mining company. The total test work timeline is anticipated to be approximately five months.

The revolutionary Rock Kleen Technology recovers a high percentage of residual silver and gold, recovers base metals, neutralizes residual cyanide, recovers nitrogen blasting residue, and recovers the critical minerals manganese, magnesium, and potassium from mine tailings. Due to Rock Kleen's efficiency at cleaning the rock, the host rock is then suitable for Industrial Minerals sales making this a "Zero Waste Energy Saving Technology".
