Two separate tenements in the Challenger district which are now wholly owned by Marmota Energy Limited are being explored for possible economic buried Challenger style gold mineralisation that may be present within Archaean basement, and also, within the large Indooroopilly licence area, for possible buried Tertiary palaeochannel-hosted roll front style sedimentary uranium deposits. Tributaries associated with major channels are seen as being likely to have prospective uranium trap sites, although the Archaean to Palaeoproterozoic rocks which dominate the known part of the hidden basement geology are generally low uranium-bearing source rocks. Therefore, Marmota now regards making investigations to discover the whereabouts of any concealed, more uraniferous Hiltaba Suite plutons as an important next step in exploring for uranium prospects in the region. To help with this investigation, a ground gravity survey covering four grids on EL 4702 was acquired during December 2011, when a total of 1743 new stations were read on regular 200 m x 200 m grid spacings, to infill earlier 500 m gravity grid coverage that was acquired by Marmota in 2008 under tenure of EL 3775, as part of the Westpoint survey. During January-February 2012, surface geochemical sampling was conducted on the same 400 m grid spacing as the gravity readings, on the first of the gravity grids surveyed over the Moonbi prospect. 113 calcrete samples, 156 soil samples and 155 biogeochemical samples of either Mulga or Black Oak tree species were collected. In addition, hand-held Niton portable XRF spectrochemical readings were obtained at each sampling location along with radon emanometry and ground magnetometer measurements (this latter work was incomplete at year end, and will be continued in Year 2). The above activities undertaken on the Indooroopilly tenement defined two potential drill targets that will require more delineation e.g. via infill calcrete sampling, before any decision to drill is made. An application was made to DMITRE for a grant of PACE Initiative Year 7 collaborative drilling project subsidy funds, to allow for the early drilling of the Moonbi geophysical anomaly to address Archaean Challenger style gold targets. The application was successful, with funds being assigned under approved project DPY7-04 for RC drilling that is scheduled to occur early in Year 2. On the Aurora Tank tenement, drillhole data from previous exploration programmes were re-assessed, and further drilling is planned to determine whether supergene gold-bearing pods exist along the shear structures in the area. Calcrete geochemical sampling is planned for the north of this tenement, where such exploration does not seem to have already been done. During the 2012-2013 project year, the aforementioned calcrete sampling was conducted within EL 4702 in March 2013. Three areas of interest were sampled on closely spaced grids (total 473 samples) to bring them better definition to serve towards selecting drilling targets, and a larger area to the east was sampled on a regional scale (101 samples). A good percentage of samples returned anomalous gold in excess of Marmota's 5 ppb threshold. The best gold-in-calcrete results were returned from Camel prospect, with a high of 23 ppb Au, and 57 out of the 155 samples collected there contained anomalous gold. Several other anomalies which warrant further calcrete sampling were disclosed by the regional sampling.
