TARGET: Diamonds in the Tallacootra - Barton - Wynbring region; precious and base metals (explored for by joint venture partners). EXPLORATION: Diamonds : Evaluation of targets generated by interpretation of an airborne magnetic-radiometric-VLF-EM survey. Follow-up work included loam sampling, Sirotem, ground magnetic and gravity surveys, and reverse circulation drilling (62 holes totalling 5483.5 m). Base and precious metals : Appraisal of existing data, and follow-up gravity surveys and percussion drilling (3 holes totalling 351.5 m). RESULTS: No diamonds, kimberlitic indicators or kimberlites were disclosed, although similar source indicators (chrome spinel) shed from altered, buried peridotite ultramafic plugs were found dispersed in overlying saprolite and soil. No encouraging results were derived from the precious and base metal exploration. The magnetic/gravity anomalies drilled were adequately explained by elevated magnetite content and higher density in basement intermediate to basic metamorphic rocks.
