Combined annual and final surrender report for EL 23684, EL 25605 and EL 25607 for the period 11 June 2003 to 23 March 2009

Abstract

The Western Creek Project area (EL23684, EL25605 and EL25607) is located 78km south west of Larrimah the licences held by Crossland Diamonds Pty Ltd, a wholly owned subsidiary of Crossland Uranium Mines Ltd (Crossland). The area is relatively unknown geologically and is believed to lie in the middle of the Palaeozoic Daly Basin, being overlain by shallow Cretaceous sediments, and younger surficial deposits. Only surficial deposits have been mapped in the area. The project area was selected using confidential technology supplied by Paradigm Geoscience. The aim of the technology is to identify targets for mineral exploration with the same signatures as major mineral deposits and thereby reduce the need to acquire large landholdings. Initially the project area consisted of a single licence, EL 23684, but following encouraging results in the first four years of tenure two additional tenements were applied for, ELs 25605 and 25607, and granted. During the first five years of tenure exploration consisted of: - Literature research of previous exploration, geological survey and geophysical survey over the EL and surrounding district. - Data compilation. - Acquisition and interpretation of departmental geological and airborne geophysical data sets. - Planning of field programs. - Field geological reconnaissance. - Rock chip sampling / prospecting. - Shallow auger drilling of poorly defined drainages and aeromagnetic anomalies. - Bulk heavy mineral sampling of gravel material from auger drilling for diamonds and diamond indicator minerals. - Processing, mineralogical analysis and Scanning Electron Microprobe (SEM) of heavy mineral samples and diamond indicator minerals. - Geochemical analysis of rock chip samples and selected auger samples. - Ground magnetometer surveys over two target areas identified by previous aeromagnetic programmes. - Interpretation of results. - Planning and budgeting. In addition, visits to other stakeholders in the area for introduction purposes were completed, and the Sacred Sites register was searched. In the sixth and final year of exploration the exploration program undertaken included: - Ground based magnetic surveys of a linear and several selected bullseye aeromagnetic anomalies. - Aircore drilling and re-sampling of selected previous auger drill holes from which chromites were recovered. - Aircore drilling of selected drainages. - Aircore drilling of a linear aeromagnetic anomaly and selected bullseye aeromagnetic anomalies. - Processing and mineralogical analysis of a single sample composited from aircore samples collected from re-samples of auger holes containing chromites and aircore holes from selected drainages. Despite encouraging geochemical and mineralogical results obtained during the first four years of exploration results from the sixth and final year of exploration failed to confirm the earlier results. In spite of this there still remains potential for economic mineralisation to occur within the area of the Western Creek Project. However as further work will require the use of more costly exploration methods Crossland has chosen to surrender all three exploration licences belonging to this project to allow it to focus its resources on more propitious projects within its portfolio.
