Annual report for EL 25881 and EL 26145

Abstract

Truscott Mining Corporation (TRM) is providing a Consolidated Annual Technical Report for two Exploration Licenses it holds in the Legune region of the Northern Territory. TRM currently holds EL 25881 and EL 26145 located in the Legune region of the Auvergne 1:250,000 map sheet in the Northern Territory. The leases are contiguous and have a total area of 76 blocks (235.38sqkm). TRM has 100% ownership of EL 25881 and EL 26145 and has grouped them together as the Explorer Project. TRM is currently managing all exploration activities associated with the leases. The leases cover an area containing particular geological structures and features of interest. TRM is planning a regional style exploration program within the project area. The authors have reviewed the tenement holding and are planning the first stage of on-ground work to effectively explore the tenements. The available geophysical data were reprocessed and reviewed in detail. The magnetics and gravity were disappointing in the sense that no obvious target oriented anomalism was evident. Fortunately however the radiometrics do show significant features that clearly warrant on the ground follow up. A program of field work is being recommended with rock chip and soil sampling along with radiometric profiling. The basement rocks in the Legune Project area could be prospective for base metal styles of mineralisation. Part of the clastic sediment pile could also be considered to be prospective for uranium or rare earth mineralisation where it overlies suitably deep seated sutures. It is reasonable to assume that the Legune Project area has not received any serious consideration for uranium or base metal exploration because it is remotely located relative to the known mineralisation in the north of the Northern Territory. In addition past Federal Government limitations on levels of production and low uranium prices severely discouraged uranium exploration over many years. The region therefore has been overlooked and remains an under explored area. With new interest and understanding it is now receiving attention for its exploration potential for a range of minerals. The aeromagnetic data proved disappointing in as much as there was no significant anomalism that could be related to mineralisation. The radiometric data have the following processing methods applied. These procedures have been defined by Grasty and Minty (1995). Statistical noise reduction techniques are applied to the 256 channel data (NASVD or MNF). The energy spectrum between the potassium and thorium peaks are recalibrated from the 256 channel measurements. The 256 channel data are then reduced to the 5 primary channels of total count, potassium, uranium, thorium and low-uranium. Dead time corrections are then applied to the data. Cosmic and aircraft background corrections are applied. Radon background removal is performed using the Spectral Ratio method (Minty 1992). Spectral stripping is then applied to the windowed data. The altimeter data are corrected and converted to standard temperature and pressure altitude. Height corrections for the stripped windows are performed to remove any altitude variation effects from the data. Counts per second (cps) are converted to equivalent concentrations (potassium % and thorium and uranium ppm) by applying the relevant sensitivity coefficients.
