The southern half of Lake Frome salina, centred about 80 km south-southeast of the Beverley uranium mine, has been explored for possible commercial quantities of dissolved lithium and uranium. Interest in the former commodity was engaged by the licensee becoming aware of a report of elevated lithium being found during the 1970s by Comalco Ltd in its trona exploration drillhole CF2. It was decided to repeat drill in the vicinity of this particular hole, to assess the subsurface geochemical anomaly using modern methods. During December 2010, a single fully cored, vertical open drillhole, WT2, was completed to a total depth of 150.3 m using sonic drilling methods, to test the Quaternary and Tertiary sedimentary sequence beneath the lake, and saline brines in the associated hydrogeological setting, for the likely presence of anomalous lithium. Drilling ceased once the hole had reached the top of the Cretaceous Bulldog Shale (picked at 149 m depth), to avoid breaching the underlying Cadna-Owie Formation artesian aquifer. WT2 intersected a thick sequence of interbedded clays and sands (fine to coarse) containing varying amounts of carbonaceous material. The recovered drill core was sampled at 1 m intervals for a partial suite of trace element assays. Elevated lithium, to 69.2 ppm Li at 27-28 m depth, was encountered within a massive brown clay unit interpreted to belong to the upper part of the Eyre Formation. 5 selected samples of the drill core were submitted for clay mineralogical determination using XRD methods. Mixed layer clays dominate the geochemically anomalous section of the hole. 4 additional samples were assayed for a range of rare earth elements. Stored drill cuttings from Comalco's earlier drillhole were re-assayed by ERO Mining at the same laboratory, for comparison of the results with those obtained by the latest hole: a close match in depth and tenor of the lithium anomaly was seen (max. value 99.4 ppm Li at 25-26 m depth). In Comalco's original drillhole report, lithium values of up to 250 ppm had been detected from assaying composite 10 m interval drill cuttings samples, in several places from surface down to 80 m depth (end of hole). Five local water bores were sampled by ERO Mining to provide background information about ambient near-surface groundwater chemistry, and six samples of water cut at various depths in hole WT2 were analysed likewise: the latter samples were also assayed for dissolved lithium, uranium and many other trace elements. No significant anomalous results were returned. A wireline downhole gamma ray log was recorded at the completion of drilling, which detected one small radiation peak at approximately 98 m depth. Apart from submission of the exploration activity basic data, no further interpretive comment was provided to DMITRE by the licensee. However, it transpired that no other work was undertaken on the subject tenements over the next 32 months, before the decision was made to surrender tenure.
