Harpe, Itronics has already tested it on virgin ore with satisfying results.
They've stated in the Jan 12 PR that The new concept was developed as an outgrowth of laboratory testing that was recently completed to evaluate the leaching capabilities of the Rock Kleen Technology. Several mining companies have inquired about gold recoverability using Rock Kleen. Testing has confirmed that Rock Kleen including conventional gold recovery technologies makes it possible to optimize recovery of both silver and gold. The new processing concept neutralizes cyanide after use and leaves the rock without cyanide residuals, making this an environmentally desirable process without the negatives normally associated with cyanide use. From this and earlier Press Releases I believe they can process virgin ore using cyanide along with RockKleen. However, they are still conducting tests looking for a way to make use of RockKleen technology without needing to use cyanide at all.
