Partial relinquished report on EL 26955 Mount Machlan

Abstract

EL 26955 Mt McLachlan is located about 220 km south of Darwin and is being explored by Thundelarra Exploration Limited/Element 92 Pty Ltd since its grant. The tenement covers a small section of the Pine Creek Shear Zone which runs north-westerly through the Palaeoproterozoic metasediments between Allamber Springs Granite, to the east, and the McMinns Bluff Granite and Tabletop Granite, to the west. The Pine Creek Shear Zone has been a major locus for the passage of gold-bearing fluids and hosts majority of gold occurrences in the Pine Creek Orogen. The fault zone trends NNW and consists of a number of sub-parallel faults, over a 5 km corridor, with apparent sinistral movement of up to 2 km. The Mt McLachlan tenement area is located in the southern part of the Pine Creek Orogen which is dominated by mudstones, siltstones, greywackes, sandstones and tuffaceous rocks which have been assigned to the Mount Bonnie and Burrell Creek formations. A desk top study of the project area was undertaken. For this purpose, data obtained during previous exploration programs were examined together with data collected by NT Geological Survey/Australian Geological Survey Organisation. Mapping conducted by the Government organisations has provided geological and structural setting of the project area in regional context which is important in evaluating mineral potential of the project area. A number of field visits were undertaken for ground-truthing and assessing the mineral potential of the project area. In addition 5 rock chip samples were taken which have not been assayed yet. During ground-truthing and appraisal of historical exploration data revealed that area relinquished did not have any potential for gold or base metals mineralisation.
