Hatches Creek EL 22912 and EL 23463 Annual Technical Report 25 July 2014 to 24 July 2015 GR262

Abstract

The Hatches Creek tungsten project consists of two tenements EL 22912 and EL 23463, located approximately 320km north east of Alice Springs. Work undertaken during the year ending 24 July 2015 consisted of resource estimation, metallurgical testwork and a sacred site survey. A maiden Inferred Resource estimate of the surface mineralised stockpiles and dumps surrounding the historical mine workings was completed identifying an Inferred Resource of 225,000 tonnes grading 0.58 percent WO3. Investigative metallurgical test work was completed on two bulk samples collected from Pioneer and Treasure waste dumps and this has shown that it is possible to produce a 42 percent WO3 concentrate with a recovery of 66 percent. The test work has also produced significant grades of Cu, Mo, and Au in the pre-float sulphide concentrate, showing potential for these to be recovered as saleable by-products. The concentrates from Pioneer also produced high Bi which is deleterious, however high Bi is only present at Pioneer and Green Diamond.
