The Kilba project is located within the Ashburton Region of Western Australia, 250km southwest of Karratha. To date, Tungsten Mining have focused on the historic Zones 8, 11 and 12 that Union Carbide discovered in the 1970s. Drilling has targeted high-grade tungsten mineralisation associated with skarns and calc-silicate units situated close to the Kilba granite.
This work has defined a JORC 2012 compliant Mineral Resource of 5.0Mt at 0.24% WO3 (0.10% WO3 cut-off). A breakdown of this resource is presented below in the JORC Resource Statements section.
Metallurgical testwork shows that the tungsten is present as coarse-grained scheelite that will respond well to conventional gravity separation. Testwork completed in 2015 has demonstrated the ability to produce an extremely high grade tungsten concentrate.
