"The metwork is top notch. CYM have managed to leach the full suite of copper minerals including secondary sulphides. The acid consumption past operators experienced is opposite to what CYM found using their expertise."
"They also managed to leach copper sulphides in Indonesia at a copper price under $3 very successfully. They are well experienced and have intellectual property that is worth patenting in regards to leachng copper sulphide including the holy grail."
CYM Hollandaire leach results had Executive Director Barry Cahill commenting “We are exceptionally pleased with the results received to date. Our expectation was that our unique leaching process would have the ability to both accelerate the leach time and produce excess acid on the Hollandaire material. The rapid leach time of the copper, using our unique leaching processes and parameters, has been astounding and outperformed our expectations.
Hollandaire VMS Massive sulfide consists dominantly of pyrite (>75%) and chalcopyrite (<25%), and lesser sphalerite and galena, although chalcopyrite is variably replaced by chalcocite, covellite and bornite.
Hollandaire Copper extraction of 91.9% on Column A in only 34 days. Copper extraction of 91.7% on Column B in only 21 days. Columns A and B net acid producing.
The initial Hollandaire metallurgical test results have shorter leach time than expected. The effect of the very short leach times on a potential project is significant as it decreases the size of the heap leach pads, and consequently reduces the capital and operating cost requirements over the life of the operation.
