Spartan Resources (ASX:SPR) said that metallurgical test work on the Never Never stages five and six, as well as Pepper orebodies, part of the Dalgaranga gold project in Western Australia, showed high average gold recoveries, according to a Wednesday Australian bourse filing.
It achieved an average gold recovery of 94.7% from test work on Never Never stages five and six master composites, and of 94% from test work on Pepper master composites, both at a grind size of 53 micrometers.
Gravity recoverable gold content averaged around 60.4% and 50.7% for Never Never and Pepper, respectively. Gravity/leach tests on master composites using base case operating conditions gave average overall gold recovery of 92.8% and 90.9% for Never Never and Pepper, respectively.
The firm and Ramelius Resources (ASX:RMS) are undertaking an integration study regarding the combination of the firm's Dalgaranga operations with Ramelius' Mt. Magnet operations. As part of this study, further metallurgical test work will be conducted to test the impact of metallurgical recovery rates when ore from Never Never and Pepper is blended with ore from the Mt. Magnet operations.
