Annual Report for the Period Ending 29 June 2009, EL 26322 (Harrison Dam)

Abstract

Exploration licence 26322 (Harrison Dam) was granted to Regalpoint Exploration Ltd ('Regalpoint') on 30 June 2008, covering an area of 7 blocks (c. 16 km2). The project area is located approximately 32 km northeast of Batchelor and 57 km southeast of Darwin, in the Rum Jungle mineral field of the Pine Creek Inlier. The project area covers a NNW-SSE-trending anticline (referred to as Harrison Dam anticline) that is cut by a NNE-SSW-striking fault (referred to as Harrison Dam fault) with greater 5 km of lateral displacement that is subparallel to and possibly linked at depth to the regional-scale NE-SW-striking Giants Reef Fault. Much of the project area is covered by recent alluvial sediments of the Adelaide River system. Regalpoint selected the area because of its potential for uranium deposits (1) along a NNE-SSW-striking Harrison Dam fault with greater 5 km of lateral displacement that is subparallel to and possibly linked at depth to the regional-scale NE-SW-striking Giants Reef Fault, and (2) at the concealed boundary between the Coomalie Dolostone and overlying Whites Formation within the core of the Harrison Dam anticline. The immediate exploration objective is to evaluate the potential of the Harrison Dam Fault in terms of hosting an economic uranium deposit. The secondary objective is to establish the depth below surface of the highly prospective contact between the Coomalie Dolostone and overlying Whites Formation, and its uranium potential. Previous exploration did not test this concept. Work during the reporting period was restricted to a review of open-file company reports and the compilation of publically available geological, geochemical and geophysical data into a GIS. The recommended work programme for the 2009-10 period is to evaluate the uranium potential of the Harrison Dam fault and concealed contact between the Coomalie Dolostone and overlying Whites Formation in the central portion of the licence area via alpha-track (radon gas) surveys and RAB and / or RC drilling of potential radon anomalies.
