Annual report EL 5906 Ban Ban, for year ending 16 March 1989.

Abstract

The tenement consists of two blocks, each one minute square, and covers approximately 6.5 square kilometres commencing 7 kilometres north-west of Ban Ban Springs Homestead. The area is located on Burnside 1:50,000, Batchelor 1:100,000 and Pine Creek 1:250,000 topographic maps and is also subject to Ban Ban Springs Pastoral Lease. Previous investigations include basemetal exploration by Geopeko and gold exploration by W.R. Grace and Western Mining Corporation. Open file reports of this activity are available at the Department of Mines and Energy, Darwin. Exploration during the first year of title was directed at gold and included detailed geological mapping and limited reconnaissance rock chip sampling. The tenement also falls within a regional aeromagnetic and radiometric survey completed for Golden Plateau NL. Geological mapping indicates horizons prospective for stratiform gold mineralisation in the Koolpin Formation. Aeromagnetic features appear to be caused by lithological variations rather than mineralisation. It is recommended that reconnaissance geochemical sampling and study of aeromagnetic data is completed. In addition prospective horizons within the Koolpin Formation should be thoroughly rock chip sampled.
