Jetti Resources has signed an agree-ment with Teck Resources to evaluate the use of Jetti's patented catalytic technology to extract copper from low-grade primary sulphides, such as chalcopyrite, bornite and enargite at Teck's copper assets. Jetti's technology integrates with existing leach technology to recover copper in ore that was previously not considered for traditional processing, including waste piles, low-grade stockpiles and areas with potential copper resources outside of existing mine plans.
