An area of the western Murray Mallee located near Blanchetown has been explored for possible economic heavy mineral sand accumulations in Pliocene raised beach strandlines. At the outset, the licensee performed a field inspection and drew up measured log sections of the prospective sedimentary strata where they are exposed in River Murray cliffs. Then, after an initial interpretation was made of available Digital Elevation Modeller coverage looking for topographic evidence of fossil beach ridges, it was decided to conduct an experimental programme of regional calcrete geochemical sampling to try to detect trace elements within this surficial medium which could denote underlying weathered target heavy minerals such as ilmenite, rutile, zircon and monazite. 491 calcrete samples were collected at a nominal 500 m spacing over a representative portion of the licence area, giving a sample coverage of approximately 1 sample per 1.5 square km. Statistical analyses of the results of multielement assaying of the calcrete samples were then performed by a consultant geochemist. Some composite indices were made of certain elemental data which might derive from the chosen heavy minerals, in order to compensate for the variation of mineral contents within the strand, variations in ground geochemistry, variations on extent of calcrete deposition, and potential sampling errors, and by so doing some linear clustering of the indexed geochemical responses was evident, which could represent the signature of buried strandlines. Limited re-sampling of the calcrete in selected places, this time along north-south oriented traverses arranged orthogonal to the interpreted strand direction, and at an infill sample spacing of 100 m, produced an acceptable degree of statistical correlation i.e. similarity in the indexed assay values, to the earlier regional sampling. To better define the strandlines so indicated, a trial low-level helimag survey was conducted over 6 areas during December 2009, hoping to pinpoint concentrations of magnetic detrital minerals likely to be present in the core zone of the postulated strandlines. A total of 696 line km of magnetic, radiometric and DTM profiles were obtained along north-south lines spaced 25 m apart, with tielines flown at 250 m intervals, at a sensor height above ground of 25 m. After reviewing the image processed data for this survey, a management decision was made that the width (<100 m) and lateral continuity of the largest indicated buried strandlines did not justify a continuation of planned work (infill helimag coverage and exploratory RAB drilling).
