TREK METALS
Nichel, Copper & Cobalt (Ni-Cu-Co)
Historic data review and re-modelling of raw data has identified several highly conductive off-hole targets at the 100%-owned Jimblebar Project in the Pilbara region of WA. The results highlight the potential for massive sulphide nickel-copper-cobalt mineralisation.

Summary
Hampton Hill Mining NL intersected semi-massive nickel-copper sulphide with 2 metres returning 1.36% nickel & 0.62% Cu from 54m in drill-hole CP007 at the Millipede East Prospect (WAMEX A089942, Figure 1). These results are indicative of a fertile magmatic sulphide system at Millipede East. The defined mineralisation correlates with modelled EM plates. The defined plates plunge in a south-easterly direction and there is potential for additional mineralisation at depth.
Previous drilling at Millipede West did not intersect the modelled downhole EM conductive plates and represents a compelling nickel-copper sulphide target (Figures 1 & 2).
Additional to the nickel-copper sulphide mineralisation the Jimblebar Project is also highly prospective for gold, sediment-hosted base metals, and iron ore.
Gold mineralisation in the district is known to be structurally controlled where subsidiary structures cross-cut major faults, shears and lithological contacts. The various Jimblebar historic gold mines and occurrences were explored extensively by Warwick Resources and Atlas Iron from 2003 to 2014. Warwick also completed a gradient array IP geophysics survey across the main workings Shearers, Sunny South and Pilliwinkle (Figure 3). The tenement covers the southern extension of the Sunny South Prospect which is located north of the company’s tenement boundary. The mineralisation at Sunny South is hosted by a 30m to 50m wide felsic to intermediate intrusive that occurs stratigraphically above the banded iron formation (BIF) and dips moderately to the east.
John Beeson of Jigsaw Geoscience reviewed the controls on mineralisation at Jimblebar and observed the gold mineralisation to be associated with a strongly pyritic and quartz-veined dacite porphyry intrusive. These intrusive rocks are interpreted by Beeson to be reminiscent of ‘mafic-series’ granitoids intimately associated with gold mineralization in the Yilgarn Craton for example Granny Smith and Sunrise Dam.
The Jimblebar Project (E52/3605, E52/3672 & ELA52/3983, Figure 4) is located 40km south-east of Newman and includes the western arm of the Jimblebar greenstone belt, a constituent of the Achaean Sylvania Inlier.
