Exploration for possible buried sandstone-hosted uranium mineralisation within early Tertiary or underlying middle Permian palaeochannel sediments of the western Saint Vincent and central Troubridge Basins, and for possible unformity style uranium mineralisation which could have formed at the stratigraphic boundary between Permian and Cambrian sediments or at the base of both of these age sequences, is being carried out within two concurrent, adjoining licence areas covering south-eastern Yorke Peninsula. A significant northwest-southeast trending fault, located west of Warooka, marks the boundary between buried Permian sediments to the east and shallower subcropping Gawler Craton basement rocks to the west. Plutons of Hiltaba Granite occur some 15 km to the north of the Coonarie Project area. During the first licence year, Marmota conducted reconnaissance field trips through both tenement areas, and reviewed all of the relevant available geophysical and geological data. During the second licence year, work done on EL 3907 included a making reconnaissance field trip that failed to locate the Kurra Murka copper occurrence reported in PIRSA spatial datasets. Due to a shift in exploration emphasis towards looking for hydrothermally emplaced uranium and other base and precious metal mineralisation, the JV partners decided to surrender EL 3908 at the expiry of its second year on 26/8/2009. An airborne magnetic survey was planned, to try to define prospective basement structures which might exist within the retained (post-first partial relinquishment) portion of EL 3907, although it was expected that the economic significance of finding any buried Hillside type IOCG mineralisation in Proterozoic crystalline basement on the southern end of the Pine Point Fault could be much reduced because of the thick (~ 1 km) overburden of Cambrian and Adelaidean carbonate and glacial sediments, as indicated by previous explorer's drilling near Stansbury. However, those same intervening carbonaceous Cambrian sequences might also host possible economic Mississippi Valley type stratiform Pb-Zn mineralisation. No work took place on EL 3907 during its third year, and a major part of the licence area was relinquished at expiry/renewal on 26/8/2010. No work took place on the remaining portion of EL 3907 during its fourth year.

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 DSD in accord with the provisions of Section 77D of the Mining Act 1971 and Regulation 88 of the Mining Regulations 2011. Marmota Energy Limited listed on the Australian Stock Exchange on 21/11/2007. The company is now in a joint venture arrangement with Monax Mining to explore for uranium on both tenements (the Coonarie Project), with Marmota earning 70% and Monax 30%. Monax has the rights to all other minerals apart from uranium that may be present awaiting discovery on both tenements.
