EL 22251 Selby Project Final report for the period 24 April 2003 to 15 January 2010

Abstract

This report documents technical work completed under Exploration Licence 22251 Selby from 24 of April, 2003, when the EL was granted, to 15 January, 2010, when the tenement was finally surrendered. The tenement area is located around 150 km southeast of the township of Borroloola in the Northern Territory. The target sought varied over time and consisted of diamondiferous kimberlitic pipes, phosphate prospects within the basal sandstone unit of Karns Dolomite and breccia pipe hosted base metal mineralisation similar to the Redbank deposit. Tenement work completed during the report period included detailed appraisal of the geology of the area and previous exploration results, which led to recognition of a significant untested target areas, rock and loam sampling, stream sediment sampling for heavy mineral analysis (HMA), airborne EM and ground gravity geophysical surveys, reverse circulation and diamond drilling and assaying. Technical work has confirmed occurrences of high grade phosphate material within the basal sandstone unit of Karns Dolomite. Selective sampling of rich phosphatic material have indicated presence of commercial grades but drilling programme failed to confirm vertical or lateral extent of this deposit. Six years of exploration programme consisting of geological mapping, sampling, geophysical surveys and drilling did not yielded desired outcome for occurrence of kimberlite or phosphate in the EL.
