Northern Vertex Mining Corp. (TSXV:NEE) announced metallurgical results from heap leach cyanidation (column leach) testwork on a mineralized material low grade bulk sample from the Moss Mine Gold-Silver project in Mohave County, Arizona, USA. Metallurgical lab test results indicate that lower grade mineralized material was readily amenable to agglomeration – heap leach cyanidation treatment at the 95% -1/4″ crush size with respect to Au recovery.
As quoted in the press release:
- Lower grade mineralized material was readily amenable to agglomeration – heap leach cyanidation treatment at the 95% -1/4″ crush size with respect to Au recovery
- Gold recovery rate was more rapid for the lower grade mineralized material vs. the higher grade mineralized material (previously reported in the Amended Preliminary Economic Assessment dated June 18, 2013)
- The column leach test recoveries were 82.7% for Au and 36% for Ag
- Lower NaCN consumption was observed for the low grade mineralized material vs. high grade mineralized material
- A relatively low cement addition (4 lb/ton ore) was required for agglomeration pretreatment of the low grade mineralized material
