Abstract: Work over the licence area included sampling programs, costeaning and drilling. Rock chip sampling at Troutbeck prospect returned peak values of 5.73 g/t Au, 7300 ppm Cu and 657-ppm As. Highly anomalous results were received from three areas. Trout 1 zone recorded a peak value of 7.04 g/t Au and 6160 ppm As. Trout 2 gave results up to 521 ppb Au and 300 ppm As. Trout 3 gave a best value of 182 ppb Au and 9900 ppm As. Costean at Trout1 confirmed the gold mineralisation and returned 8m @ 5.6 g/t Au. At Trout 2 costean assays defined a zone of 35 m @ 0.13 g/t Au. Ten rock chip samples were collected to define the source of mineralisation identified in costeaning. Additional costeans were excavated at the Trout1, 2 and 3 and results confirmed that anomalous zones are confined to metasediments at the margin of dolerite. Higer grades are associated with the Troutbeck Fault. Follow up RAB drilling delineated several anomalous gold zones with greater than 200 ppb Au. The extensive width and open strike length of gold mineralisation of Trout 2 suggests that this zone may have greater economic potential than Trout1, which exhibits high grade but poddy gold distribution. The 3 ground magnetic traverses were surveyed to determine the magnetic susceptibility of subcropping dolerite dykes within the prospect area. Gold mineralisation is localised at the boundaries of these dykes and the Lander Rock Beds, therefore any technique, which could define, that margins of these dolerites would be advantageous. Six RC drill holes were drilled to test for primary gold mineralisation beneath a supergene blanket. Drilling intersected siliceous, sericite altered interbedded sandstone and mica schist, with lesser doleritic rocks. Results from drilling included 8m @ 9.42 g/t Au from 32m (including 1m @ 70.1 g/t Au). Generally low order gold anomalism with occasional high values were intersected. It was concluded that gold mineralisation was sporadic and there was limited potential for economic mineralisation.
