During the first year of combined reporting for exploration licence 2675 “Ediacara”, 2593 “Blinman’ and 2627 “Wilkawillina”, the exploration focus was primarily on the Ediacara tenement. During mid-1999, Perilya reviewed the Ediacara Mineral Field, located 25 km west of its Beltana zinc deposit, as part of its regional evaluation of Cambrian basin base metal prospectivity, and identified it and the surrounding synclinal sub-basin as prime locations for exploring for additional zinc mineralisation. The Ediacara lead-silver-copper deposits, which are situated within a synclinal sub-basin made up of Lower Cambrian carbonate and siliclastic rocks, are classed as being of epigenetic stratabound, structurally controlled Irish type, and have been formed adjacent to large, basin-wide normal fault structures. They occupy favourable breccia horizons in Cambrian carbonate rocks, close to the Woodendinna Dolomite – Parachilna Formation contact. The principal ore consists of galena, cerussite and malachite, plus accessory sphalerite, and is associated with limonite, manganese, haematite and silica alteration. A strong structural control on the lodes appears to have been exercised by the Gap Creek Fault; other similarly orientated structures control lesser known gossanous mineralisation that lies on the margins of the sub-basin. Because the drill cores from 80 past diamond holes completed at Ediacara are stored at the PIRSA Core Library, these cores were systematically infrared scanned by Perilya to test them for zinc, as the majority had not previously been assayed for this element. 89 core samples were then taken from 5 holes where encouraging indications of zinc content were noted. All of these holes had been drilled in the central eastern area of the Ediacara synclinal basin. Inspection of the core from the depth interval 76.8-83.7 m in SADM hole E44 (which returned sample assay values of 6.9 m @ 1.32% Zn, 0.012% Cu, 0.063% Pb and 3.4 g/t Ag) showed that the anomalous zinc is present in a clay/breccia zone located 3 m above the contact between the Parachilna Formation and Woodendinna Dolomite. White clay, zinc oxide and dolomite are present in this interval, with the majority of the core being broken and friable. At the commencement of field work, six days were spent by Perilya undertaking geological mapping and reconnaissance. Mapping was completed at 1:2500 scale over the Greenwood and Moorish workings, and at 1:5000 scale over the remainder of the Ediacara prospect. Photo enlargements of 1:44,000 scale Government air photos were used. Three days were spent GPS locating streams and roads for mapping purposes. 384 soil samples were collected by Perilya at 50 m x 100 m and 50 m x 200 m centres across the eastern portion of the Ediacara prospect, and to the south of the historic Black Eagle copper workings, and 17 rock chip samples were also collected for analysis. The soil samples were sieved to separate the minus 2 mm to plus 20 mesh size fraction for analysis. Assay results disclosed a large area having elevated zinc and multi-element geochemistry. During November 2002, Perilya drilled 7 vertical RAB holes with an aggregate penetration of 353 m along three traverses crossing a conceptual stratabound zinc target in the NE of the mining field. Mineralisation was intersected in hole BTB542, with 11 m @ 2.1% Zn and 4.82% Pb from 26 m depth, including 3 m @ 2.86% Zn and 12.82% Pb from 28 m, and 2 m @ 5.1% Zn and 3.87% Pb from 35 m. The ore minerals encountered are galena and sphalerite, occurring in the equivalent stratigraphic position to the lodes at the historic Greenwood and Moorish workings. The new-found mineralisation is blind, and is controlled by the NNE-trending Central Fault which lies 250 m south of BTB 542. Perilya believed that an estimated 9 Mt @ 5% Pb and 2.1% Zn might potentially exist over a 500 m x 300 m area; however, a significant increase in the drill-tested zinc grade would be needed to make an economic discovery. Nevertheless, the initial intersection had vindicated the concepts and rationale used to target this north-eastern part of the mining field. Exploration on Blinman consisted of a soil survey where 65 samples were collected over the Ti Tree Gorge Bore prospect, sieved to -2 mm+20# size fraction and analysed got Cu, Pb, Zn, As, Sb, Ag, As, Bi and Cd. Significant results were returned with a peak 6558 ppm Zn, the area is characterised by extreme relief with peak anomalism located along an inaccessible ridgeline of Wonoka formation. The geology is strongly fractured, limonitic dolomite with traces of zinc oxides along fracture planes. The target is open north of the anomaly where the access is better. Exploration on Wilkawillina consisted of 1 day of mapping at the Linda Prospect at 1:2500 scale. The prospect is characterised by outcropping pods of hydrozincite directly replacing sandy/brecciated Wilkawillina Limestone. There appears to be a strong lithological control to mineralisation, along a large 330° trending structure. During the second year of combined reporting of the Flinders Ranges Project, the exploration focus during the period was at Third Plain within Wilkawillina EL 2627, where RC drilling was undertaken. No work was completed on Ediacara during the reporting period, while a reconnaissance visit was made to Blinman where a cherty dolomitisation alteration halo was observed between the #2 karst and the Backwater Springs Fault. The karst and alteration halo has yet to be mapped in detail, but the observation suggests the karst is highly prospective for zinc oxide mineralisation. On Wilkawillina, 7 RC holes for 657 m were drilled into the Third Plain Prospect. Drilling was targeting outcropping mineralisation associated with the Third Plain fault, the Footwall fault and historic mineralised drill intercepts. The drilling identified a plunging mineralised shoot at the intersection of the major NE-SW trending vertical Third Plain fault and the N-S trending, E dipping Footwall fault. The mineralisation is plunging to the NE and remains open in this direction. During the third year of combined reporting for the Flinders Ranges Project, no significant field exploration was conducted on the Ediacara and Blinman tenements, with exploration being focused on the Third Plain Prospect within Wilkawillina (EL 3273). At Ediacara, a number of splits from anomalous intersect from previous drilling programs were assayed for a wider selection of elements. It was found that a good correlation between Pb-Ag; Pb-Zn-Cd exists, and that Ba is enriched in the footwall of the higher grade intersections. Additional geological and assay data from previous company and Government drilling were obtained from PIRSA open file reports and have been added to the database for the area. Database validation was completed with all available data reviewed and corrected where necessary. Stratigraphic units have been assigned to all described geological intervals to enable a more accurate picture of the structure and stratigraphy to be determined. Preliminary geological cross sections have been prepared for the area to allow a more complete interpretation to be undertaken. It is clear from the initial review of the sections that several drill holes failed to intersect the target stratigraphy. On Wilkawillina RC drilling was undertaken within ML 4386, which is fully enclosed within EL 3273, to test the Willemite mineralisation on the Third Plain Fault. Eleven holes for 1004 m were drilled (TPC008 – TPC018), with 210 5-metre composite samples submitted for Cu, Pb, Zn, Ag, As, Mn, Bi, S, Cd and Sb assay, while 37 1-metre splits were assayed for Pb, Zn, As and Si. The best intercepts included hole TPC013 from 65 m with 4 m @14% Zn and TPC016 from 91 m with 1 m @ 21% Zn. During the fourth year of combined reporting for the Flinders Ranges Project, work during the year included soil and rock chip sampling at Wirrealpa, Ediacara and Blackwater Springs, with field visits to Fountain Head, Wepowie, Linda and Third Plain. On Ediacara effort was put into location 20 historical drillholes, correcting a number of database inaccuracies in the Black Eagle Copper Mine area. Cross sections and a drill hole location plan showing mineralised intervals were produced for the Ediacara area after databases and most hole locations were validated. Three target areas with shallow Pb-Ag-Cu-Zn potential have been identified, and a further target area in the vicinity of Black Eagle Cu working has been identified, which is more structurally complex, deeper and Cu rich. Eight rock chip samples were collected from various old mine workings across Ediacara for geochemical analysis. Two samples approximately 230 m apart in the southern working area returned significant results with maximum values of 55.7% Pb, 9.03% Cu, 0.19% Zn, 0.16 ppm Au and 159 ppm Ag. Perilya is funding and supporting Sarah Harman, with the University of Missouri, with a Masters Project in the area. Sulphide samples for age dating and willemite and gangue samples for fluid inclusion and isotope work (Pb and S isotopes and fluid inclusion work) were collected from various prospects around the Flinders Ranges. The southern workings were visited at this time and spectacular secondary lead and copper mineralisation was noted. On the Blinman tenement a half day field visit was completed to the Blackwater Springs Prospect, 38 soil and 40 rock samples were analysed using the Niton portable handheld XRF machine, returning soil assays of up to 2281 ppm Zn and 6396 ppm Pb, and rock assays of up to 1.70% Pb and 5.45% Zn. Elevated rock samples were sent to laboratory for follow up analysis, with significant base metal results returned with maximum values of 3.45% Pb, 5.57% Zn and 78 ppm Ag. Two rock samples were collected from the Wirrealpa Lead Mine. Samples were also collected for use in the Masters Project discussed earlier as well as from the Wilkawillina tenement. During the fifth year of combined reporting for the Flinders Project, no exploration work was completed on the tenement group. During the sixth year of combined reporting for the Flinders Projects, no exploration work was completed on the tenement group. A one-week reconnaissance trip to Blinman EL 3221 was undertaken and aimed to highlight prospective areas for future exploration. No samples were collected. During the seventh year of combined reporting for the Flinders Project, Perilya resumed exploration activities on the tenement group. Work completed on the Ediacara tenement (EL3384) consisted of Niton sampling of several historic diamond drill-holes (26) completed on the tenement. Results of up to 8.5 m @ 1.8% Cu and 4 m @ 3.5% Pb. Niton XRF soil sampling (2346 readings) and infill geological mapping were completed at the Blackwater Springs prospect on the Blinman tenement (EL3221) defining a new zone of zinc anomalism to the north of the historic workings displaying >1,600 ppm zinc. No exploration was conducted on the Wilkawillina tenement (EL3273). During the eighth year of combined reporting for the Flinders Project, no work was completed on the tenements during the reporting period. A large portion of tenement EL3221 (now EL4388) was relinquished in late 2009 upon renewal of the Amalgamated Expenditure Agreement.
