An area consisting of three separate sub-blocks that are spread out ~25 km north of Manna Hill and from 10 to 20 km to the north and north-west of Olary is being explored for possible economic gold as basement shear and vein hosted style deposits, as well as for possible extensions of the uranium mineralised felsic basement of Radium Hill and Crocker Well, and for possible younger Mt Gee - style breccia/shear hosted uranium deposits that may be genetically associated with Palaeozoic Delamerian and Alice Springs orogenic fault reactivations. The start of exploration on the subject tenement was not possible during Year 1 because the company was awaiting the release by Geoscience Australia of its processed 2010 airborne EM survey data, which was delayed until March 2011, and because Renaissance had to abide by ASX rules requiring corporate inactivity during a share IPO period. During licence Year 2, field work began that involved soil geochemical sampling during April 2011 over an aeroradiometric anomaly lying within the central sub-block of the licence (125 samples collected on a 200 m x 200 m grid), accompanied by limited rock chip sampling (15 samples). Assaying returned elevated gold values of between 4 and 9 ppb Au in three places. During licence Year 3, extensive first pass soil geochemical sampling was conducted on all of the licence sub-blocks, with a total of 1675 samples collected at 300 m x 300 m grid spacings. High tenor assay results were returned, notably from Duckpond prospect at the eastern sub-block, which yielded a peak gold response over Proterozoic gneiss of 161 ppb Au, the highest gold value that Renaissance had obtained to date from any of its Curnamona Province licences. Other promising bedrock targets within Proterozoic gneiss at Ameroo and Adelaidean metasediments at Mulkulpara were supported by multiple elevated gold assays, including a peak response of 126 ppb Au at Mulkulpara. Plans were made to quickly start doing infill to the regional soil sampling, at either 100 m x 100 m or 50 m x 50 m spacing, to prioritise the three currently identified geochemical anomalies for drill testing. During licence Year 4, a further 323 soil geochemical samples were collected at 300 m x 300 m and at 100 m x 100 m infill grid spacings, which better defined three discrete gold and base metal anomalies. However, the follow-up sampling done at Duckpond failed to repeat the high gold response. During licence Year 5, no field work was done. Desktop studies involved analysis of the 2013 soil sampling data in conjunction with geophysical, geological and geochemical surface data. During licence Year 6, no field work was done. An attempt was made to sell the licence, but this failed. During licence Year 7, six grab rock chip samples of a pegmatite that was suspected to carry spodumene were collected and assayed. One of the samples contained 143 ppm Li. During licence Year 8, attention shifted onto defining copper-cobalt targets through a review of existing geochemical data, including historical data. This suggested that some potential targets may lie within the easternmost licence sub-block. During licence Year 9, no work was done.
