Slide 5: Project Status
PROJECT STATUS • Drilling to increase the resources has not been possible since acquisition due to permitting delays which are now essentially resolved • Drilling around the historical Burnt Hut, Wild Kate and Mt Everard workings is scheduled to commence in January 2017 pending favourable weather co
Slide 6: Mineral Processing and Products
MINERAL PROCESSING AND PRODUCTS • The host rock is silexite, composed mostly of an intergrowth of quartz 80% and topaz 20% • The tungsten occurs as Ferberite, a tungsten-iron oxide in large masses or finely disseminated • Ferberite has a high density and can be separated after crushing using simple
Slide 7: Results of Bulk Sample Testing Phase
RESULTS OF BULK SAMPLE TESTING PHASE CRUSHING AND SCREENING: • Following earlier phases of testwork on portions of the bulk sample to formalise a processing route, the remaining 720kg with an average grade of 0.36% W was then processed accordingly • First step was wet impact crushing to minus 1mm an
Slide 8: Results of Bulk Sample Testing Phase (Cont)
RESULTS OF BULK SAMPLE TESTING PHASE (Cont) PRIMARY SPIRAL CONCENTRATION OF +300MICRON PRODUCT: • The calculated head grade of the +300micron fraction was 0.14%W • Spiral concentration on the +300micron fraction showed a recovery of 58.4% of the test feed to concentrate grading 3.2% W in 5.2% mass y

Slide 12: Criteria Applied for Tungsten Plant Flowsheet
CRITERIA APPLIED FOR TUNGSTEN PLANT FLOWSHEET A much simpler flowsheet (see next slide) compared to what was envisaged has resulted from (a) the highly successful X-ray Transmission (XRT) ore sorting trials (ASX 18 October 2016) and (b) the equally successful magnetic separation testwork on cleaning
