Recovery of Copper by Solution Mining Methods 3 Supplementing production from conventional heap leach operation the in-place rubble leaching project at Silver Bell is estimated to recover 20 to 25% of the contained copper The relatively low recovery achieved by this method is most likely due to the presence of insoluble hypogene Phase 1 - a small project based on a near-surface oxide copper A definitive feasibility study ('DFS') was conducted during 2014 This has now been revised to a smaller "Mini Mining" proposal in order to expedite project development Phase 2 - a much larger project based on the deeper sulphide copper resource
