Asanko Gold Inc. (TSX:AKG,NYSEMKT:AKG) announced positive results from a metallurgical test work program conducted at its recently discovered, near-surface Dynamite Hill deposit. It is located 7 kilometers from the soon-to-be-constructed processing facility at Asanko’s Ghana-based Asanko gold mine.
As quoted in the press release:
The metallurgical test work program, conducted by Metallurgy Pty Ltd in Western Australia, was undertaken to assess the gravity and cyanide leach amenability of the oxide, transitional and fresh material from the Dynamite Hill deposit, as well as the comminution characteristics.
The results have confirmed that the material from the deposit presents consistent and similar leach kinetics to the other deposits which make-up the Project. It is expected that the Dynamite Hill material will blend well with the ore from the other four Phase 1 Project pits; Nkran, Adubiaso, Abore and Asuadai and confirms that the standard gravity and Carbon-in-Leach processing facility designed for Phase 1 is appropriate for treating material from Dynamite Hill.
Results of metallurgical testing show that the gold recovery averages between 93.2 and 96.2% across the various mineral types with an average of 95%. Gravity gold separation test work indicates that approximately 50% of the gold is expected to be recovered in the gravity circuit. Comminution testing indicates that the Bond work index varies between 10 kWh/t for softer oxide ore and 16 kWh/t for the harder fresh material, which is a similar range as the other deposits at the Project.
