An area centred ~185 km west of Tarcoola, and lying immediately south of the Trans Australia Railway line, was taken up to explore for possible economic buried IOCG type mineralisation hosted by buried basement rocks of the western Gawler Craton, as well as for any large heavy mineral sand placer deposits that may occur within the overlying Tertiary Eucla Basin fluvio-marine sedimentary cover. During the 2005-2007 reporting period, Red Metal's initial activities included interpretation of historic drillhole data for evidence of a palaeo-strandline that may have buried mineral sand potential, and the planning of shallow aircore drill traverses to test for inferred concealed mineral sand occurrences in the eastern part of the licence area. During the 2007-2008 reporting period, Red Metal prepared, and then lodged with PIRSA for approval, a Declaration of Environmental Factors (DEF) for its proposed drilling programme. A field trip to the remote licence area was undertaken in mid-2008 to evaluate access for a drilling rig. During October 2008, Geosolutions were contracted to fly a 593.3 line km airborne EM (REPTEM) survey across the eastern part of the licence along ENE-SSW orientated flight lines spaced 500 m apart, using a sensor mean terrain clearance of 35 m, to try to map the stratigraphy of the Tertiary sediments and to define the underlying basement topography. During the 2009-2010 reporting period, intended drill sites were pegged and a Work Area Clearance Survey was completed with representatives of the Far West Coast Native Title Claimant Group, which did not identify any sites of cultural sensitivity in their vicinity. The commencement of drilling was then delayed to allow for the conduct of complementary drilling on associated joint venture tenements in the Eucla Basin. On EL 3495, up to 3600 m of drilling was planned at nominal 400 m hole spacing along four traverses occupying the interdunal corridors to minimise environmental impacts. 87 vertical aircore holes with a total penetration of 3291 m were completed during May 2010, to test targets recognised in the AEM survey data. Hole spacing over ~25 line km of traverses 3-4 km apart averaged 300 m, closing down to 150 m in places of interest. These holes encountered a thin, broad low grade HMS mineralised strandline over 15 km of its strike length, within part of the Barton palaeo-coastal embayment. No high grade HMS accumulations were found, and Valuescan laboratory analysis of composite cuttings samples covering the best 3 mineralised intervals showed a lower than expected valuable heavy mineral grain content, indicating a strand placer mineralogy that is strongly affected by weathered rock trash. However, AEM targets lying nearer the southern headland of the embayment remained to be fully tested, so it was hoped that they could hold higher grade HM deposited in more effective trapping situations. Following the renewal of the JV's licence tenure for a second term, the partners reviewed the drilling results from EL 4777 in conjunction with those obtained from other Eucla Basin tenements operated by Cristal Mining, to allow for the ranking of untested or partly tested prospective targets. During licence Year 7, in July 2013, Cristal Mining acquired part of a multi-licence, 10,946 line km fixed wing airborne magnetic/radiometric/DTM survey over all of EL 4777, along east-west flight lines spaced 100 m apart, using a 20 m mean sensor height above the ground surface. The relevant 6699 line km subset of survey data is herewith released to open file. Data were sent to contractor Vector Research Pty Ltd for signal enhancement processing and gridding, using radiometric channel spectral ratios to try to resolve coherent anomalies. The stated aim of flying this detailed regional survey was primarily to map basement geophysical features which could be prospective for metallic mineralisation. During licence Year 8, Cristal Mining received and interpreted the processed 2013 airborne radiometric survey data to generate four HM exploration targets. Financial constraints meant that these targets could not be drilled immediately, but the preliminary office based planning and permitting work was begun, including the writing of a Program for Environment Protection and Rehabilitation to submit to DSD for approval. The company planned to drill ~60 holes along four traverses that follow interdune corridors (swales). During licence Year 9, no field work was done. Cristal Mining finalised preparations for its intended drilling campaign of 63 holes for 2268 m. However, protracted dealings with the Far West Coast Aboriginal Corp. for gaining land access permissions caused the delay of the start of drilling. A partial relinquishment of 286 square km or 49.5% of the former area of EL 4777, in two separate portions running down its eastern and western sides, was made on 28/9/2015. During licence Year 10 (2015-2016), no work was done. During licence Year 11 (2016-2017), the joint venture between Red Metal and Cristal Mining Australia was concluded on 21/6/2016. EL 5888 was granted 29/9/2016 as a subsequent tenement to EL 4777; the area was reduced from 578 to 292 square km. Red Metal sought a replacement joint venture partner with expertise in heavy mineral sands. No field work was done within the reporting period. During licence Years 12 and 13, no work was done, pending clearance by the native title group. During licence Year 14, no field work was done, pending clearance by the native title group. During the current period, Red Metal assessed the potential for the tenement to host base metal mineralisation by compiling and modelling regional geophysical and drilling data, with an aim of outlining targets in the Proterozoic basement rock that may have potential to host nickel-copper mineralisation. A magnetic anomaly in the north – western corner of EL 5888 was identified as a possible target for further exploration. During licence Year 15, no field work was done pending field clearance by the native title group. Following on from a review completed in the previous reporting period, Red Metal concluded that the identified basement anomalies probably do not represent a viable exploration target, which downgraded the area’s basement potential. However, significant potential for heavy mineral sands was still recognised, which warrants further investigation. A renewal application for the tenement was made (but was subsequently withdrawn in 2022). During the final licence year (Year 16), no work was done.
