Could a new Jetti Resources breakthrough unlock low grade

These low grade resources contain more than 70 of the world s copper reserves and they cannot be processed using traditional leaching processes Standard leaching techniques on primary copper ores are blocked by a hard non reactive coating which forms around the crystal structure of the ore.
