McEwen Copper Reports Improved Copper Recovery
The test results were produced utilizing conventional bio-heap leaching technology and generated an average copper recovery of 76.0%.
- The test results were produced utilizing conventional bio-heap leaching technology and generated an average copper recovery of 76.0%.
- The recovery results for the residual copper (CuRES) component shown in Figure 2 indicated an average recovery of 25%, an increase of 10% from the 15% preliminary recovery assumption used in the PEA.
- The additional residual copper recovery when applied to the entire resource increases the overall average recovery from 72.8% to 76.0%.
- Figure 3 below illustrates the increase in potential copper production throughout the mine life, attributable to the improved recovery, in comparison with the PEA assumptions.
