A large, 705 square km area surrounding Kimba township was taken up to explore for possible economic buried deposits of Mount Isa or Broken Hill style base metals (Cu-Pb-Zn-Ag), and Tanami style lode gold. The licence lay in the northern part of the Cleve Domain of the Gawler Craton, where the regional geology is dominated by basinal sediments of the Paleoproterozoic Hutchinson Group, including some banded iron formations, that overlie a basement comprised mainly of Archaean and Palaeoproterozoic gneisses. During 2006, the licensee commissioned geological consultancy Geointerp to do a bedrock structural and stratigraphic interpretation of the tenement area, using all existing aeromagnetic survey data and open file geological information available from PIRSA. The resulting report is appended herein to the licence Year 1 annual report. After conducting a literature review and some reconnaissance field visits early in 2007, Ellemby Resources believed that the highest priority targets on EL 3645 were three north-westwards trending linear magnetic anomalies that traverse the eastern part of the tenement, the most prominent one being ~10 km long. It was thought that these features could be associated with possible Wilcherry Hill type magnetite-altered, breccia-hosted gold deposits, as they appeared broadly comparable to the aeromagnetic signature seen at Wilcherry Hill, so probably occupied a similar geological setting. They also lie between two known Hiltaba Suite plutons, at Buckleboo and Lake Gilles respectively. These magnetic features were presently underexplored. Their sources did not appear to outcrop, and very little geochemical sampling had been done over them due to the lack of a calcrete soil horizon and the presence of transported cover. No drill testing of them had been done. During July 2007, 13 rock chip samples were taken from various outcrops in paddocks and roadsides in the EL where the rocks (quartz veins and outcrops, ironstones and BIF bodies, altered metasediments, etc.) appeared to have a reasonable chance of containing anomalous trace metals. Areas where previous explorer's calcrete sampling work had shown some level of anomalism were also visually inspected, looking for possible outcrops or float that might indicate the nature of the basement rocks subcropping in the vicinity of these calcrete samples. The resultant assay values were disappointing overall, with only 4 samples recording extremely low levels of gold, plus weakly anomalous results for other elements. During October 2007, a programme of orientation calcrete sampling was carried out in the east of the EL, to try to establish whether this priority area did in fact have reasonable calcrete development, contrary to the thoughts of previous explorers, particularly Aquila Resources. As well, 8 rock chip samples of outcropping BIF in the south-west of the tenement were collected to find out if they had any economic potential as iron ore. The assay results were again disappointing, except for those coming from a calcrete sampling traverse made across one of the target narrow N-W trending magnetic features, where 5 samples did arguably show a general elevation in concentration of gold, copper and nickel compared to the rest of the data, albeit somewhat incoherently, meaning that follow-up sampling would be warranted in this area. ************* Hiatus in this licence's detailed abstracted work history and dataset content, due to separate joint reporting done by Investigator over the period 2008 to 2010. Briefly, on the subject licence in Year 2 activities comprised soil geochemical sampling plus gravity surveying, both performed on 1 km x 1 km grids; in Year 3, the soil sampling coverage was infilled to 500 m x 500 m grid spacing, and the bedrock beneath one resulting single point soil uranium anomaly at the Paracombe prospect was later tested by drilling a single traverse of 4 vertical aircore holes for 281 m, with unremarkable results; in Year 4, further infill soil sampling was done at 250 m x 250 m grid spacing. ************* During licence Years 5 through 7, no field work was done. During licence Year 8, limited soil geochemical sampling (50 samples collected on a 250 m x 500 m grid) was undertaken in November 2014 ~5 km east of Kimba to test for possible anomalous silver dispersions in the cover surrounding a 50 ppm Ag silver intercept, which was detected from re-assaying of stored bottom hole samples of a 1985 Pasminco drillhole in the area. This drillhole's location coincided with a magnetic anomaly, which the soil sampling grid was designed to overlie. A best assay value of only 58.7 ppb Ag was returned, with most samples having a much lower silver content. No further work occurred during licence Years 9 through 12, before the decision was made to allow tenure to lapse.

Notes: This release to the public of the subject mineral exploration data, namely, company data which was acquired more than 5 years ago, is being done by DMITRE in accord with the provisions of Section 77D of the Mining Act 1971 and Regulation 88 of the Mining Regulations 2011. ***See Env 11811 for separately held joint annual reports covering work done on EL 3645 over the period 2008 to 2010 inclusive.** Investigator Resources Ltd entered into a joint venture with Ellemby Resources in 2008, agreeing to spend $450,000 during the first two years to earn a 51% holding in the Kimba Project. Investigator entered the joint venture because the ground was within a belt of land considered prospective by Investigator (the Tarcoola - Moonta corridor), and had not been effectively explored for IOCG type deposits. Ellemby Resources withdrew from the joint venture with Investigator Resources on 28/10/2014, so Investigator assumed 100% ownership of EL 4938. Investigator had been operating exploration on the tenement since May 2008. Includes: - Rankin, L.R., May 2007.
