The third year (April 2015 to March 2016) saw the project progress to phase two drilling. A program of RC and diamond core drilling (DD) totalling 11,389m was completed. In parallel to the drilling there were studies on the metallogeny and geochronology, mapping and logging (both lithological and geotechnical) and airborne geophysics. Preliminary metallurgical testing was also carried out on two RC holes which showed amenability to sulphide flotation and oxide leaching. These programs confirmed JO as major, newly-discovered PCD, hosting oxide and sulphide mineralization as well as identifying numerous other targets delineated across B62, including new PCD targets around JO.
With the confirmed identification of JO as a PCD, the mapping and logging practices were converted to the “Anaconda” style during year four (April 2016 to March 2017). This was a major change in approach and it enabled the various veining systems within the porphyry to be correctly described and mineralising domains identified. Phase two drilling continued into phase three with a total of 13,130m being drilled. Three dimensional modelling of the deposit commenced to firstly complete an in-house JO mineral inventory demonstrating significant content of Cu & Au and secondly in preparation for the maiden Mineral Resource Estimate (MRE).
