Final report EL 7829, Marmbulligan, 01-06-1993 to 13-12-1996

Abstract

129 gravel samples were collected. 105 were negative and 4 returned a single microdiamond with the remainder reporting chromites. Follow up of the chromite bearing samples failed to verify the initial results. 49 loam samples in total were collected from 3 grids. 1 sample returned a single microdiamond while a second (sample BAU04770) returned 10 microdiamonds. Resampling of the latter location failed to reproduce the original result. 1 x 50t bulk sample was collected and analysed. Results were negative. Other work included 3 small helimagnetic surveys (totalling 256 line km) were completed. No targets were identified and 131 line km of DIGITEM were also acquired. 2 small conductors were identified. 3 RAB holes drilled to test conductors returned negative results.
