Report for Limestone Creek 12 months Jan 87 to Jan 88.

Abstract

Exploration Licence 5146, 'Limestone Creek' was examined with the aim Of detecting possible platinum-group element mineralization similar to that detected in BMR Hay River 11A. The prospect can be compared with platinum-group element mineralization in the basal black shales of the Zechstein Deposit in Poland. No drilling was carried out in this area due to difficult access but drilling was carried out in nearby Exploration Licences 5145, 5147 and 5149. Results from the analysis of the drill cuttings for Pt, Pd and Au were all below the limits of detection. Possible explanations for the low results are; erosion or non-deposition of mineralized horizon and underlying rocks, geochemical and environmental differences, absence of favourable post depositional environments. Further exploration is recommended, especially in the untested area of Exploration Licence 5146. Drilling should be carried out by a rig suitable for sandy environments.
