First annual report for EL 25610 Prince Henry

Abstract

Uramet Minerals Ltd identified the potential for stratiform copper mineralisation and sandstone-hosted lead mineralisation in the Mt Skinner area. This report details exploration work carried out by Uramet Minerals Ltd within the Prince Henry tenement (EL25610, Fig. 1) in the Northern Territory for the 2007 field season. The tenement was transferred from Elkedra Diamonds NL during the 2007 season and covers an area of 32km2. Exploration consisted of regional reconnaissance work and examination of historical drill core. Regional field reconnaissance was carried out in July and October 2007 with promising anomalous copper results returned. A review of open file exploration reports and drill core data indicates that Mt Skinner is prospective for stratiform copper mineralisation (Fig. 2) in the Neoproterozoic Central Mount Stuart Formation and epigenetic base metal mineralisation in the Elyuah Formation. Copper mineralisation occurs on the surface and extends for several kilometres along strike and consists of malachite-stained rocks and float (Dunster et al., 2007; Fig. 2). Visible galena, pyrite, chalcopyrite and fluorite were described by Dunster et al. (2007) in core CMS4 (immediately north outside the tenement) at a depth of 247m to 260m. Whole rock geochemistry carried out during the same study confirmed elevated lead, zinc and barium levels and revealed previously unrecognised lead-zinc mineralisation at depth. Reconnaissance work was carried out in July and October 2007. Outcropping malachite-bearing siltstone and associated float were investigated in the wider project area. Selected core intervals of one historical drill hole from the Prince Henry area (CMS2) was inspected at the NTGS Alice Springs Core Library and analysed with a portable Niton XRF. The results for CMS2 could not confirm any significantly elevated base metal values. Further field work is planned to map the extent of the basement rocks including granitoids.
