EL 25242 Final report incorporating Year 3 Annual report 12 September 2006 to 11 September 2009 Green Alligator Project

Abstract

Field work on EL 25242 has consisted of ground radiometrics and rock chip sampling. The mapped stratigraphy has been verified. The tenement has been prematurely surrendered in order to concentrate on adjoining tenements. Rock chip samples were collected on the reconnaissance traverses whenever a different stratigraphic unit or gossanous material was encountered. Their locations were GPS recorded, the lithology described, a sample number assigned and a 1-2 kg sample submitted for assay. Total count scintillometer readings were taken at approximately 20 metre intervals along all traverses. If on an EW or NS traverse, control was by maintaining the GPS reading. On an irregular traverse along a creek or fenceline readings were taken at approximately paced intervals of 20m.and the GPS reading recorded. All rock samples were submitted to the Darwin based laboratory, Northern Territory Environmental Laboratories (NTEL). Assay methods and detection limits were chosen commensurate with the grades expected. Samples were routinely analysed for Cu, Co, Ni, Pb, Zn, U and Au. The field work completed has given a good regional overview of the mineral potential of EL 25242. The reconnaissance geological mapping has indicated most NTGS interpreted geological units to be present albeit in places misplaced by up to 100m. Radiometric traversing of TC (gamma) has shown no clear relationship with different stratigraphic units as mapped. Except for one reading of 700 c/s no obviously anomalous readings have been recorded. Several slightly anomalous assay values were obtained such as: sample 110668 from EL 25242 returned anomalous value in Ni and Zn from a sample of Koolpin Formation. The high radiometric reading of 700 c/s from the Acacia Gap Quartzite which assayed 20 ppm U.
