An area surrounding the historic copper-mining town of Blinman in the central-northern Flinders Ranges has been explored for possible economic diapir-related copper mineralisation, similar to that encountered nearby at the formerly significant Blinman and Nuccaleena mines. These mined-out occurrences are located within breccia-cored domal features that have often been ascribed to the effects of mobilised Willouran salt plugs. The mineralisation is generally hosted within dolomitic units that are surrounded by variably brecciated rocks, these being predominantly heavy mineral - banded and halite cast - bearing quartzite and siltstone lithologies. The intersection of structural features with mainly N-S, NE-SW and NW-SE orientations, which are evident in regional magnetic data and are translatable to veinlet orientations within the various prospects, suggests that moderate to strong fault activity may have increased host unit permeability at the time of mineralisation. Sedimentary units such as dolomite and grey shale seem to be the most common hosts to mineralisation, probably by virtue of their reactivity to the saline and relatively oxidised fluids that are interpreted to have transported the copper within the mineralising system. During the first licence year, 41 rock chip samples collected from sites spread across the tenement gave several significant copper values, and revealed associated elevated antimony, a potential pathfinder. 8 of these rock chips were sent off for petrographic examination. At three prospects located on the Blinman Dome (Blinman Extension, Breakneck Gorge and China Wall), auger soil sampling was conducted on 100 m x 25 m grid spacing (1033 samples collected). A particular sampling method was chosen which it was hoped would reduce the effect that a long history of mining activity may have had on near- surface soils, as well as to reduce any dilutant effect that clays and sands might impose on detection of a soil response from weathered sulphide mineralisation or supergene oxide and carbonate mineral - sequestered mineralisation. A statistical correlation of the soil sample assay results indicated a strong relationship between copper and arsenic. Several very anomalous copper values were returned. Additional re-assays were planned, using a multi-acid digest method (near total digest) that would include Al, Mg and Ca to allow better differentiation between the geochemical responses coming from different soil compositions. 1:2500 scale geological mapping was also conducted on these prospects, which Helix had chosen on the basis of its reprocessing and interpretation of available geophysical and drillhole information. Over the period June-July 2008, Helix acquired a detailed airborne magnetic/radiometric survey across EL 3814, at 100 m line spacing and 40 m sensor flight height, for an overall coverage of 7509 line km. During the second licence year, another 26 rock chip samples were collected and assayed. Samples from the China Wall prospect returned up to 0.4% Cu, others from the Mafic Alley prospect returned up to 2.7% Cu, and up to 4.6% Cu was returned from an historic small mine located east of Oratunga Homestead. 13 of these rock chips were sent off for petrographic examination. In further auger soil sampling, a total of 2925 samples of the minus 40 mesh soil fraction were collected on a range of grid spacings, usually along 100 m spaced lines with sampling intervals varying between 100 m, 50 m or 25 m. Attention was directed at the Mafic Alley, Eastern and Blinman North prospects in an effort to define and interpret the anomalous footprint of mineralisation in these areas. This sampling successfully outlined several broad geochemical anomalies. Values of greater than 500 ppm Cu were usually related to visible Cu mineralisation in nearby outcrops. Two 100 m x 25 m grids of gradient array IP surveying were completed at the Blinman North and China Wall prospects to try to identify chargeable features in the subsurface which could reflect prospective rock units. A further 5 traverses of dipole-dipole IP readings were acquired over the Blinman North prospect to confirm a mapped chargeability response (indicated buried sulphides) and to allow modelling of the depth and dip of target bodies. During September-October 2008 Helix directly investigated its newly defined geochemical and geophysical anomalies in the Blinman North area by drilling 14 RC holes (60 m rotary mud plus 2233.5 m RC) with 3 diamond cored tails (BLN001, BLN005, BLN007 : 819.6 m cored), as a PACE Initiative Year 5 partly government-subsidised project: this was followed by another 3 RC holes for 414 m (BLN008-BLN010) drilled in the China Wall area. RAB hole PTNB001 was also drilled as a water bore at Patterson Pool on Gum Creek Station, to provide water for the drilling programme. Helix concluded that significant correlatable lithology, alteration and mineralisation may exist beneath the Blinman mine, as determined by drillhole BLN001. In addition, RC hole BLN011 drilled from a position located approximately 700 m west of the mine returned a 120 m wide, average 600 ppm Cu mineralised intercept lying below a soil geochemical anomaly and close to a strong dipole-dipole chargeability response. However, inversion models of the IP chargeability response indicated that the drillhole was completed down dip/plunge of the anomaly, so this then suggests that the true width of the mineralisation intercepted may not be as substantial as the drilling results seem to indicate. No other field work was performed on EL 3814 during licence years 3, 4 and 5. An office-based review of the remaining untested exploration targets led eventually to a decision to surrender tenure.
