Copper Range is exploring a number of the Springfield Project mineral tenements for base and precious metals under the terms of a joint venture agreement that it made with licensee Flinders Diamonds on 19/3/2007, whereby the latter retains all rights to conduct diamond exploration, while Copper Range could earn up to a 90% interest in the non-diamond rights by conducting said exploration over a three-year period. The farminee company's interest in this particular acreage within the Adelaide Fold Belt is predominantly focussed on exploration for copper, where it may occur as near-surface oxide deposits and as sediment-hosted stratiform sulphide mineralisation. Large alteration zones formed within formerly porous and permeable extensive sandstone units are being targeted for preference as being sites wherein copper-bearing fluids potentially may have penetrated along favourable structures that cross-cut the strata, and may subsequently have precipitated copper at reducing horizons, onto available organic material or disseminated pyrite. Copper Range's initial interpretation of airborne radiometric and ASTER satellite imagery, with inputs from expert-assisted studies of lithology, basin subsidence and Adelaide Fold Belt regional geology, identified several base metal targets within the Springfield Project tenements. During 2007, the following exploration activities occurred: - At the Kanyaka mine prospect on EL 3265, copper oxide mineralisation contained in small shears exposed in old workings was investigated by drilling 11 RC holes for a total penetration of 670 m. This drilling did not disclose a structurally-controlled oxide blanket within siltstones of the Parachilna Formation, as had been hoped, although patchy and low grade copper carbonates were encountered by almost every drillhole. However, mobile metal ion (MMI) soil sampling (199 samples) done over a fault zone identified further base metal anomalies that might be tested by drilling. Further drilling was also planned to test the Pound Quartzite, a potential host to primary copper sulphide mineralisation at depth. - At the Kanyaka North prospect on EL 3265, MMI soil sampling (84 samples) was undertaken over a showing of copper oxides found in a small costean. The sample analysis results did not suggest any significant extension of the known mineralisation. - At the Black Jack prospect on EL 3265, MMI soil sampling (191 samples) was undertaken along lines laid out across strike, to follow up anomalous stream sediment results recorded from previous exploration. The results were inconclusive. - At the Cradock Road prospect on EL 3265, MMI soil sampling (176 samples) was undertaken along lines laid out across the strike of prospective strata. No geochemical anomalies were detected, and no further work is planned at this prospect. - At the Radford Creek prospect on EL 3693, MMI soil sampling (361 samples) was undertaken on a grid that covered both an area of previous surface copper oxide workings, and the extension of the inferred controlling structure. This sampling highlighted significant anomalies along strike to the east of the workings, that require further geochemical sampling and possibly drilling. - At the James Range which is located on ELs 3919 and 3070, stream sediment sampling (66 samples) was performed to look for copper anomalism associated with altered quartzite bedrock mapped by ASTER imagery. No anomalies were detected. - At the Copper Claim deposit on EL 3131, a sediment-hosted copper occurrence that does not outcrop, a review of Utah Development Co.'s past exploration work and a compilation of previous drilling and sampling data were undertaken. In addition, University of Sydney student Rosemary Elkington's B.Sc. (Honours) project was completed on her mineralogy and petrology studies of Copper Claim drill cores. During 2008, Copper Range undertook further exploratory RC drilling at Kanyaka in order to test a buried sandstone/quartzite unit that occurs physically (but not stratigraphically) beneath the outcropping Parachilna Formation siltstone that hosts the copper oxide mineralisation. Six holes for 362 m were drilled in total : 3 were drilled in the vicinity of the mine workings, while 2 were drilled at Kanyaka North prospect to test zinc soil anomalies, and another hole was sited to test an IP anomaly located by Kennecott in the 1970s. In the Kanyaka mine area, the two holes drilled near the pit did not reach their target depths due to water influx and boggy ground conditions. The third hole successfully penetrated sandstone beneath silcreted cover, but did not encounter any sulphide or oxide mineralisation. At Kanyaka North, no mineralisation was located that is associated with the soil zinc anomalies, nor was the source of the IP anomaly able to be identified. At Black Jack prospect, further MMI soil sampling (105 samples) was undertaken to follow up on several anomalies detected in 2007. Four additional lines perpendicular to strike were sampled. No significant anomalies were detected, and it was decided that no further work was warranted. A magnetic anomaly was located in EL 3265 near Wilson. It occurs within Cambrian limestones and was considered to have potential for finding Beltana-style zinc silicate mineralisation. Three lines of geochemical soil samping (52 samples) were undertaken across this anomaly, but no base metal anomalies were detected. At Radford Creek prospect, more MMI soil sampling (413 samples) was undertaken in an area of outcropping ferruginous dolomite to the south of the previous coverage; this identified both copper and zinc anomalies. Corresponding geological mapping done by Adriaan van Herk indicated that these anomalies relate to N-S and E-W trending structures. However, previous exploration reports mentioned that a single drillhole had been put in by Kennecott Exploration during 1967 within the main anomaly, which did not locate significant mineralisation. Therefore Copper Range's plans to drill this prospect were abandoned. Ongoing evaluation of the Copper Claim deposit on EL 3131 Gilbert Hill comprised a detailed prospectivity review undertaken by Joseph Ogierman, who applied Copper Range's sandstone-hosted copper exploration model to the area, targeting possible mineralised epigenetic feeder zones within the underlying quartzite. As part of this review he made visits to PIRSA's Core Library to inspect stored drill cores originating from previous drilling done by Utah Development Co. in the 1970s. Stream sediment sampling results previously obtained by Utah from elsewhere on the Carrieton Anticline were also reviewed, and several previously disregarded anomalies were field inspected, with reconnaissance mapping and rock chip sampling of these locations. Reconnaissance exploration of the Eurelia prospect was also undertaken, because Copper Range's literature research had shown that in the past there a company called Jedda Exploration had outlined an "announced resource of 500,000 t @ 1% Cu" : unfortunately, no records of the supporting drilling data appear to remain. The conceptual targets generated by Joseph's review were not followed up due to lack of available funds. When during June 2008, Flinders Mines commenced flying detailed helicopter-borne low level aeromagnetic surveys (with 100 m spaced flight lines and 30 m sensor height above ground) over selected areas in its Springfield Project acreage, to aid its diamond exploration programme, Copper Range paid to extend the survey coverage to include EL 3693 Radford Creek and EL 3265 Kanyaka. All of the raw helimag data was later obtained from Flinders Mines and reprocessed for Copper Range by a geophysical consultant. The company's intent was to investigate the base metal potential of dilational sites ('jogs') evident on the aeromagnetic imagery as being present along the Orroroo Lineament, a regional structure associated with the well-known G2 tectonic corridor. This irregular structure cuts across the Carrieton Anticline, and shows evidence of past strike-slip movement. It was proposed that certain of the sites, where hydrothermal fluid flow might possibly have occurred, should be tested by RAB drilling during 2009. However, it transpired that a change of corporate policy made in early 2009 moved Copper Range's exploration focus onto a search for iron ore. Only limited work was done in this regard, consisting of office-based research and reconnaissance field checks of four ironstone occurrences. None of these were considered worthy of further attention. Copper Range decided in January 2010 to withdraw from its Springfield Project farm-in obligations, and to return full control of the project to Flinders Mines.
