Exploration of an onshore area located immediately north of Murat Bay aimed to discover beach or shallow marine placer concentrations of zircon-rich heavy mineral sands, possibly formed within significant thicknesses of prospective Upper Tertiary Ooldea Sand that occur beneath Quaternary dune cover on the eastern margin of the Eucla Basin. The Ooldea Sand unit comprises shallow marine - reworked dunal sands incorporating fossil beach strandlines, which elsewhere in the region contain known significant heavy mineral resources. During June-July 2006 exploratory shallow aircore drilling (37 holes for a total penetration of 856 m, being part of a joint venture programme of 157 holes totalling 4156.6 m spread across both Watraba Project ELs 3363 and 3364) was carried out to test an interpreted J-shaped bay and headland feature visible in the satellite imagery digital terrain data: this feature was inferred to have existed in a similar palaeogeomorphic setting and at a comparable topographic level to other such features that host Iluka's Ambrosia, Jacinth, Tripitaka and Gulliver heavy mineral discoveries. Red Metal's drill traverses were regularly spaced around the interpreted headland feature, with drilling restricted to fence lines and road verges; drillhole spacings varied from 800 to 1600 m along these traverses. Most of the drillholes reached the Precambrian basement (saprolitic clays and quartz derived from granite). The drilling and sampling failed to disclose any significant concentrations of economic heavy minerals. It was found that the present-day exposed basement high is flanked by Ooldea Sand sequences comprising fine to very fine grained quartz sands, which are interpreted to represent offshore (littoral) depositional facies. It appears that Recent erosion of the Ooldea Sand sequences has exposed the basement high, forming the present-day headland like topography. It is now believed that with respect to the Murat Bay licence area the historic Ooldea shoreline prospective for heavy mineral sand deposits is located further east, or has been eroded from the profile. It is also thought that only limited potential remains in this area for finding Gulliver-type heavy mineral concentrations in the deeper water Ooldea Sand facies. Following the exit of farminee Rio Tinto, Red Metal conducted an unsuccessful search for another joint venture partner during 2007-2008. In July 2008, 7 RAB holes totalling 238 m were drilled on an aeromagnetic low (possible mafic/ultramafic intrusion within the basement) to assess its magmatic nickel potential. As expected, weathered mafic rocks were encountered, but the downhole sample assay results were not anomalous for trace metals. Because of the lack of exploration success, the licence was surrendered in April 2009.
