Development of Tungsten Ore Industry-V

In 2012-13, Thomson Resources continued exploratory drilling of magnetic targets within the southern part of the undercover Thomson Orogen in northwest NSW. Drilling on the eastern flank of the company's F1 anomaly (Falcon project) in early 2013 intersected anomalous tungsten (best intercept of 0.3% W over one metre), molybdenum and minor gold (Au) in what may be a zoned system. Previously, Thomson Resources reported on earlier drilling on other prospects in the Thomson Orogen which intersected evidence of mineralised hydrothermal systems. Two of these targets (Cuttaburra project) gave high grade polymetallic intercepts, with grades up to 3.7 grams per tonne (g/t) Au and to 113 g/t silver (Ag) as well as to 0.4% Bi, to 0.5% Cu, to 1.8% Pb, to 0.8% Sn, to 0.6% W and to 4.25% Zn. Mineralisation is reported to occur as sheeted and stockwork veins up to one metre wide within zones of altered basement rocks of the Thomson Orogen. On the basis of the polymetallic assemblages and presence of granite, Thomson Resources has suggested an intrusion related gold style of mineralisation for the mineral systems intersected so far. Tungsten, present as scheelite, appears to be a common feature of the majority of these mineral systems.  Thomson Resources announced in June 2013 that it had reached agreement with Cuttaburra project joint venture partner Raptor Minerals Ltd to acquire 100% of the project.
