An area of the southern Gawler Craton, which is located on Eyre Peninsula east of Elliston, is continuing to be explored for possible economic buried Archaean to Proterozoic bedrock-hosted primary base and precious metal deposits of inferred epithermal VHMS or magmatic intrusive nickel-rich type. Licensee Alphadale renewed tenure of the area in its own right following the ending of successive earlier joint ventures with BHP Billiton and Anglo American which had enabled significant exploration to be conducted during the early 2000s (see Env 8957). The subject EL 3301 currently consists of three separate sub-blocks that lie close to the faulted southern margin of the Polda Basin aulacogen, a probable source of migrating saline and reactive hydrothermal fluids over a long period of time. During the first licence year, 21 line km of ground magnetic surveying were completed over the Oakdale, Tooligie and Bramfield prospects that had already been defined from previous work (aeromagnetic data interpretation) done on prior EL 2622. Ground magnetic readings were made at 5 m station intervals along 7 traverses, and the resulting data, besides those from aeromagnetic profiles crossing the Bramfield prospect, were modelled by Euro Exploration to delineate drill targets. Drilling of selected prospects was commenced during January 2006, after the licensee was successful in obtaining two grants of PACE Initiative Year 2 collaborative drilling project subsidy funds to allow it to perform campaigns of diamond core drilling that would allow better interpretation of local bedrock geology and structuring. During licence Year 2, the campaign of exploratory diamond drilling was resumed, with 8 holes completed for a total penetration of 1744.8 m (544.6 m of rotary mud precollars, plus 1200.2 m of HQ/NQ2 diamond coring). Four of the holes encountered subeconomic multiple thin zones of Zn-Pb-Ag-(Mn) mineralisation within interpreted exhalative banded pyrrhotite rich sulphidic horizons and fault breccias developed in felsic gneisses. A fifth hole intersected a slightly sulphidic, magnetite rich (upper gabbro) to magnetite poor (lower olivine-bearing pyroxenite) mafic-ultramafic complex which may represent a fractionated aluminous basalt, while two other holes at Bramfield encountered marbles, calc-silicates and an eastwards dipping, base metal - bearing skarn containing disseminated and vein magnetite (37.8 m @ 40.40% Fe with low P (865 ppm) and 3171 ppm Mn in hole BLDD06). [Full results of the two PACE subsidised drilling projects are reported separately in Envs 11184 and 11185]. A low level airborne helimag survey covering a large part of the subject licence was acquired by Alphadale during July-August 2006, with ~2600 line km flown along east-west flight lines spaced 100 m apart at a nominal 25 m sensor height above the ground surface. Coverage included the western licence portion covering the Bramfield prospect, and about half of the eastern side covering the Oakdale, Malache and Tooligie prospects. Detailed ground gravity readings were made at the Bramfield and Oakdale prospects (total 674 new stations) during January 2007, at variable grid spacings of between 800 m x 200 m and 200 m x 50 m. A total of 584 calcrete samples were collected from traverses made across areas with known anomalous base metals, initially for reconnaissance purposes and then as infill over newly revealed anomalies. At the start, sampling was confined to the north-west and south-east extensions of the interpreted Malache trend, and also to the Tooligie area which may represent additional Malache style mineralisation, but after seeing encouraging results, the survey was later extended to cover parts of the Oakdale prospect. Results indicated that the method could have application in areas having shallow cover. Distinctive zinc anomalism was evident over the Malache area, with calcrete assay values ranging up to 29 ppm Zn, but no coherent anomalies could be seen. Values for lead were generally below detection limit, with some spot anomalism associated with the main Malache trend. Copper showed an anomalous grouping on the eastern margin of the Malache prospect, plus spotty anomalism further along interpreted main structural trend. Uranium values were subdued, and the other elements assayed did not show any markedly anomalous values. The Tooligie area, which has thicker cover, showed no discernably anomalous data. During licence Year 3, another 15 rotary mud precollared, NQ2 diamond drillholes for 4946.0 m (BLDD09 - BLDD23) were completed by Alphadale at the Oakdale, Malache, Bramfield and Kappawanta prospects. The drilling undertaken at Oakdale (and over part of the Kappawanta magnetic anomaly located on EL 3126) represented approved PACE Initiative Year 4 collaborative drilling project DPY4-52 [for its drilling final report see Env 11514]. As part of the assessment of drill core sample geochemistry, 240 core samples from the Bramfield Iron Prospect were analysed for a comprehensive suite of elements associated with iron deposits. A further 32 samples from the Kappawanta Iron Prospect were also assayed for this suite. Davis Tube metallurgical testwork was completed on 5 samples from hole BLDD10 drilled at Bramfield. During licence Year 4, assay results were received for infill and extension calcrete sampling done at the Malache prospect. Further assaying of an additional set of drill core samples was undertaken, and brief petrological examinations were made on these samples. A detailed geological appraisal of the Bramfield Iron Prospect was completed, which allowed a structural model of the iron oxide mineralisation to be developed and an inferred resource to be estimated, which is ca. 100-150 Mt. A large drilling programme was designed to provide subsurface data that would quantify this estimate. Preliminary detailed discussions were held with PIRSA and DWLBC concerning how to effectively and responsibly explore the Bramfield iron ore occurrence, which is situated beneath a local groundwater basin containing a vulnerable water resource. During licence Year 5, joint venture negotiations were begun with Anglo American Corp., and separate discussions were held to try to attract a partner for the Bramfield Iron Project. The lignite potential of the Tooligie Basin was investigated, with 2 carbonaceous sediment samples collected from hole BLDD01 for coal analysis. During licence Year 6, the first of renewed EL 4537 Brimpton Lake, which was now under the ownership of public company Lymex Tenements Pty Ltd, that company acquired a low level helimag airborne magnetic survey in late May 2011 to better outline the extent and configuration of the Kappawanta gabbro intrusive complex, and to closely delineate the Mount Cora regional aeromagnetic anomaly as a potential BIF iron ore prospect. 1891.2 line km were flown along east-west lines spaced 100 m apart, using a sensor mean terrain clearance of 30 m. The Mount Cora anomaly had originally been investigated by very widely spaced regional aircore drilling performed by BHP Billiton, which had indicated the presence of probable hematitic iron formation by encountering 12 m @ 35.95% Fe in hole BLAC1035. Lymex therefore tested this target with 15 vertical aircore holes for 1056 m that were drilled along a single traverse designed to cross the apparent strike direction of the earlier intercept. Due to farmland cropping operations, the traverse was located approximately 100 m to the south of the discovery drillsite. One of Lymex' drillholes failed to reach basement and was redrilled. 174 predominantly 3-metre composite drill cuttings were assayed, but only minor trace metal values were returned and no significant iron assays were recorded. Another 6 vertical aircore holes for 284 m were drilled by Lymex at the Malache East prospect to investigate some strong linear anomalies that it was thought might be part of the Oakdale prospect Archaean komatiite sequence. Unfortunately, drilling difficulties resulted in only one hole reaching identifiable bedrock; 3 holes were terminated while within saprolite, and 2 holes failed even to reach saprolite due to large marcasite fragments in sands blocking the drill bit. 18 predominantly 3-metre composite drill cuttings were assayed, but no significant geochemical values were returned. During licence year 7, exploration work comprised preparation of an EWA for drilling and completion of a limited diamond drill programme including core sample assaying, performing metallurgical test work and petrology on samples of mineralisation from the Tooligie lignite prospect, the Kappawanta Gabbro iron prospect and the Oakdale graphite prospect, and the conduct of a detailed structural analysis of the Bramfield iron prospect. A single diamond cored hole, BLDD024, was drilled to 312.4 m to test the western portion of the Mount Cora aeromagnetic anomaly as detailed by the 2011 helimag survey. While the drill site was not able to be located in the best position to test the anomaly due to access constraints, sufficient magnetite - bearing gneisses were encountered to explain the observed magnetic anomaly. These gneisses are considered to be of too low a grade to warrant further testing. Additional aircore drillhole samples from the Tooligie lignite prospect were submitted for coal analysis in a specialist laboratory. Despite the results being significantly better than those obtained previously, the samples' ash content was too high. More suitable material is expected to be obtainable from deeper within the basin proper, and so further drilling of the area will be required to determine the potential of the basin to contain a significant lignite resource. Ongoing mineralogical and metallurgical assessment of the Kappawanta gabbro iron prospect for its potential to contain a large, low grade deposit of coarse grained magnetite beneath shallow cover, has determined that the magnetite can be recovered to a suitable concentrate grade by using a relatively coarse grind, although the content of some potential penalty elements remains high, and the bond work index has also been noted as being of concern. 132 drillhole samples from the Oakdale prospect were submitted for analysis for their graphitic carbon content, in view of the recently emerging international market demand for high quality processed natural graphite. A detailed structural interpretation of the Bramfield magnetite prospect was undertaken by consultant Roger Marjoribanks. The outcome, although differing in some ways from the current interpretation of Lymex personnel, was not able to disprove that interpretation, and thus additional drilling is required to establish the actual structural picture. During the 2012-2013 reporting year, 3 inclined diamond holes for 312.4 m were drilled at the Oakdale graphite prospect (68.5 m cored), to obtain more drill core samples of the graphite schist to submit for metallurgical testwork. A further 111 samples were submitted for laboratory graphitic carbon analysis. A preliminary report on their May 2012 testwork results was made by the mineral processing consultants. They observed that there is a large variation in graphite particle size over short distances within the host rock, and that intercalated silica or alumina is still present within the very fine, mostly minus 75 microns graphite fraction dominating the mineral concentrates so far produced by grinding and flotation separation tests. Chemical and/or thermal purification will likely be necessary to remove these intercalated contaminants, in order to improve the product purity and ensure conferring maximum electrical conductivity in the most common industrial applications of high grade graphite. At this stage of the investigations, best indications were that the following products can be produced from mineral concentrates of graphite derived from the Oakdale occurrence oxidised zone: ~2-5% 'jumbo' graphite (>425 microns); ~30% medium–fine graphite (75 microns); ~30% fine flake graphite (38 microns); and ~20% as amorphous graphite. During the 2013-2014 reporting year, no work was done. During the 2014-2015 reporting year, after concluding a successful capital raising, intensive activities were begun, mainly directed at further assessing the Oakdale graphite prospect and also the Oakdale East graphite prospect lying ~3 km away to the east, as follows: - an 11.92 line km gradient array IP survey was completed by Zonge during December 2014 over a portion of the Oakdale prospect; - an interpretation of existing aeromagnetic data for Oakvale was performed to establish the strike direction of the basement strata and model any structural features which could influence deciding about where to do intended resource delineation drilling; - 289 inclined exploratory aircore holes for 16,570 m, plus 5 inclined or vertical diamond cored holes for 295.5 m, were drilled at Oakdale and Oakdale East during the period March to July 2015 to obtain 4602 rock samples for assaying of their graphitic carbon content, and four drill core samples were submitted for metallurgical testwork to determine the particle size distribution of graphite grains and contaminant mineral material. All of the aircore holes were drilled to blade refusal, which is generally just below the base of the main saprolite zone. The aircore holes were drilled at 25 m intervals along traverses spaced 50, 100 and 200 m apart, these being aligned approximately perpendicular to the interpreted strike of the units. All basement rock penetrated was sampled at 1-metre intervals before the samples were composited to 2-metre intervals for assaying. The drilling campaign was still underway at the end of the reporting period. During the eleventh, 2015-2016 reporting year, on renewed EL 5721, Lymex completed its big aircore drilling campaign targeting graphite mineralisation, with 41 additional holes for 2554 m. Six diamond cored holes for 308 m were also drilled to obtain samples for metallurgical testing. From these holes another 1136 rock samples were submitted for assaying of their graphitic carbon content, and drill core samples were submitted to determine the particle size distribution of graphite grains and contaminant mineral material. 421 specific gravity measurements were made on both historical and current drill core samples. In-house petrographic and mineralogical investigations were continued. Maiden JORC-compliant global graphite resource estimates were calculated for the Oakdale and Oakdale East deposits, yielding a combined total Indicated and Inferred resource of 13.474 Mt at a 3.3% TGC cut-off grade. During the 2016-2017 reporting period, activities included potential marketing and production avenues, which have continued to be investigated. No significant field activities were completed during the period. During the 2017-2018 reporting period, the tenement area underwent a significant reduction of ~42% and now covers an area of 349 km2, in accordance to the ARA that covers the tenement. No field work was undertaken during the reporting period, with efforts focussed on sourcing additional funding for the development of the Oakdale Graphite Prospect.
