Paleoproterozoic metasediments of the Hutchison Group, and Lincoln Complex granitoids, were the targets of exploration for gold, base metals, and granite dimension stone in an area 40 km south of Kimba. In reporting year 3 for EL 2858, no field work was undertaken and therefore no new technical data generated, as such no technical report was submitted for the year ending 16th October 2004. In reporting year 4, following a review of dimension stone deposits held by the company it was decided that several diamond cored holes form the Schubert Red Granite Deposit were required before pegging a Mineral Claim was justified. A number of samples of the granite were cut and polished for distribution to potential customers. No metals-based exploration work was undertaken. Several companies initiated contact for possible farm-ins, by the end of the reporting period no Joint Venture Agreements had eventuated. In reporting year 5 the tenement was purchased from Olliver Geological Services Pty Ltd by Pirie Resources in June 2006. During the reporting period a 2 day field trip to the tenement was undertaken along with a desktop review. In reporting year 6 on renewed EL 3711 for the period to 19th February 2008, Archer Exploration defined several areas of immediate exploration potential and has completed an airborne magnetic survey and radiometric survey. Archer is targeting the magnetic anomalies on the EL, focussing on the strong magnetic features in the southwest of the tenement. Previous exploration identified manganese rich units at the surface and iron rich units at depth. They seek to expand on this information and determine the continuity in depth and strike of the manganese and iron rich units, with the aim of locating economic quantities of manganese and iron. In December 2007 UTS Geophysics were commissioned to fly a magnetic, radiometric, and digital terrain data survey, a total of 586 line-km was completed on a 200 m line spacing. At the time of reporting the data from the surveys was still being processed which will allow for target generation. In reporting year 7, field work undertaken by Archer included the drilling of 18 inclined Reverse Circulation (RC) holes for 2001 m as well as the completion of an electromagnetic (EM) survey (63.4 km flown) over parts of the tenement. A soil sampling survey (143) was conducted over parts of the tenement along with rock chip sampling (182). In June 2008, Archer commenced initial drilling at its Carappee Hill tenement, which was focused on iron and manganese mineralisation at the Jamieson Tank Prospect and copper and gold at the Bender Prospect (Sugar Loaf Hill) to the southeast. Encouraging results were returned from holes at the Bender Prospect; drillhole CHRC010 from 105 to 113 m averaging 0.15g/t gold, 0.15% copper and 8g/t silver, drillhole CHRC012 from 48 to 56 m averaging 0.16g/t gold, 0.14% copper and 3g/t silver, and drillhole CHRC017 from 64 to 68 m averaging 0.36g/t gold and 0.02% copper. Magnetic targets have been drilled and magnetite iron ore potential has been identified, however due to the overburden Archer does not see this as a viable target for immediate exploration. The gold, copper and uranium potential of a mineralised structure has also been defined. Results from rock chip sampling following the drilling campaign have confirmed that significant gold and copper mineralisation does outcrop at the surface at the Bender Prospect. Archer intends to identify the gold mineralised host rocks over the strike of the prospect, which, coupled with detailed structural mapping, will allow for a greater understanding of the mineralised structure, and assist in planning future drilling programs. In reporting Year 8, exploration work undertaken by Archer has included rock chip sampling over the Bender Prospect for copper and gold, petrological work, a gravity survey, and an aircore drilling program. Additional work was performed on the Bender prospect to understand the extent and controls on mineralisation, this included close spaced rock chip sampling and the collection of ground gravity data. The Pindari magnetic anomaly was focussed on during the year to gain an understanding of the mineralisation potential of the structure. The aircore drilling program saw 206 holes drilled for 1705 m to test a known bedrock EM anomalism and potential nickel anomalism while gathering wide-spaced bedrock geochemical information. The initial drilling was successful in identifying a nickel geochemical anomaly which appears to be circular in nature. Eight holes reported nickel grades over 0.1%, these same samples also reported chromium grades more than 0.1% each, as well as copper grades averaging 140 ppm. Rock chip sampling (264) was completed along the Bender structure with the aim of identifying discrete anomalies from the surface. Fourteen samples reported above 100 ppb gold and 11 samples reported above 0.1% copper. Five samples reported above 5 ppm silver, with the highest-grade reporting with 0.1g/t gold. The gravity survey was conducted with the aim to provide contrast to the EM and magnetic data collected previously. Stations were collected on a 100 m spacings along lines between 200 to 400 m apart, a total of 156 station points were collected. Gravity surveys identified an anomaly below the Bender prospect. Petrological work identified nickel sulphides in historic holes at Pindari (holes Pindari 1 and 2 drilled by Greater Pacific Investments in 1987). A joint Venture was entered into with OM Holdings (which Monax Mining Ltd is the operator) to explore for manganese and ferrous materials over a 4-year period.
