Hatches Creek EL 22912 and EL 23463 Annual Report 25 July 2013 to 24 July 2014

Abstract

Work in 2013-2014 focused on establishing an estimate of the above ground resource available for exploitation in the hatches Creek Mineral field and a process to extract the economic minerals Wolfram, Scheelite, Copper and gold. A total of 107 bulk and rock samples were taken from historically mined areas; Pioneer, Black and Green Diamond, Treasure Group, Hit and Miss and other minor historic workings. Results from the sampling work indicated that grade of the waste dumps and tailings averaged between 0.5 percent and 1 percent WO3. A volume survey was also completed establishing that approximately 200,000 tonnes of waste rock material in the form of waste (mullock) dumps and battery tailings could be available for treatment. Preliminary metallurgical testwork was completed and indicted that economic recoveries could be achieved with the best result of coming from the Hit or Miss Area with test work on the composite sample C (generated from the mullock sampling) producing a concentrate of 47.5 percent WO3 recovering 74 percent of the contained WO3.
