Final and Annual report on EL 28857 (Second Chance) Allamber Project for the period 24 February 2017 to 15 June 2018

Abstract

Exploration Licence (EL) 28857 is located about 180 km SSE of Darwin and approximately 50 km NE of Pine Creek. It consists only one block and is part of the Allamber Project and is being explored for copper, gold and uranium mineralisation. The Licence was granted to Element 92 Pty Ltd, a wholly owned subsidiary of Thundelarra Limited on 24 February 2012, and after successive renewals, it was expected to expire on 23 February 2019. However, due to lack of mineral potential and land access issues it was surrendered on 15 June 2018. The project area is located in the central part of the Pine Creek Orogen which is a folded sequence of Paleoproterozoic pelitic and psammitic sediments, with interlayered cherty tuff units. These rocks have been intruded by the late-orogenic Paleoproterozoic granites, causing wide-spread contact/thermal aureole which contains much of the gold and other mineralisation in the Orogen. The geology of the project area is dominated by the Paleoproterozoic rocks of the Namoona Group, Mount Partridge Group and the members of the Cullen Batholith. Main lithologies are tightly folded dolomites, sandstones, ferruginous shales and quartz-andalusite schists which have been intruded by the Allamber Springs Granite. This geological sequence has potential for gold, base metals and uranium mineralisation. During the term of the Licence, the project area was explored for base metals, uranium and gold mineralisation. Exploration activities commenced with collection and interpretation of historical exploration data which identified mineral potential of EL 28857. On ground activities included geological mapping, geochemical survey, geophysical survey, drill core logging and assaying. Processing and interpretation of exploration data identify some potential for base metals mineralisation but not sufficient enough to continue exploration. Furthermore, access issues also hampered exploration activities. After a thorough review by the company led to surrendering the tenement on 15 June 2018.
