Tungsten Mining NL is pleased to report that drilling continues to intersect significant high-grade tungsten mineralisation at the Kilba Project in the Gascoyne Region of Western Australia. To date the Company has drilled 24 diamond holes and 43 reverse circulation (RC) holes for a total of 7116 metres. The Company commenced drilling in November 2012 to confirm the presence of high-grade tungsten mineralisation indicated by historic drilling completed by Union Carbide Corporation in the 1970s/1980s. Current drilling is targeting Zone 11 located on the 100% owned and granted Mining Lease 08/314 (Figure 1). Exploration has completed an 80 metre by 40 metre spaced drill pattern over the main 900 metres of outcropping mineralisation at Zone 11. Broader spaced drilling has also tested strike extensions on 80 to 160 metre spaced sections, for a further 300 metres.

Tungsten Mining Managing Director, Paul Berndt, said the excellent high-grade results received from the drilling confirms the Company’s belief in the Kilba Project and justify its focus on the rapid evaluation and development of the Kilba Project. “To this end the Company has engaged CSA Global to model mineralisation present at Zone 11 with the objective of producing a JORC-compliant Resource by May,” Mr Berndt said. “We are on target to create significant project value at Kilba, by completing a feasibility study within a year." The final analytical results have been received from 46 of the 59 holes drilled in 2013, confirming the high-grade nature of coarse grained scheelite mineralisation present.

Work undertaken to date indicates tungsten mineralisation dips at 30 to 70 degrees toward the south to southwest and is associated with skarns and calc-silicate units. Typically high-grade mineralisation is associated with retrograde skarn units that are often surrounded by low to medium grade disseminated scheelite mineralisation in calc-silicate and sedimentary units. Figures 3 and 4 show the different styles of mineralisation and geometry. Three diamond core holes were drilled to twin RC holes to compare drilling techniques and local variability or the nugget-effect of tungsten mineralisation. Diamond holes generally intersected similar widths of mineralisation to the RC holes, however the grade of mineralisation was highly variable as shown in table 3. Further diamond twinning will be conducted to evaluate the best method to cost-effectively define mineralisation present at the Kilba Project.
