Year 4 relinquishment report for EL 24392 Thring Creek

Abstract

This report documents all exploration carried out on the surrendered area of EL24392 (Thring Creek) at the end of Year 4 between 5th December 2005 and 4th December 2009. Previous exploration has suggested that aeromagnetic anomalies over the Thring Creek tenement represent similar magnetite skarn bodies to that found at Molyhil. Molyhil is a magnetite-rich skarn that has a bulls eye shaped aeromagnetic anomaly associated with it. In December 2005, Sunsphere completed a 2 week, 1 man, 25m x 200m ground magnetic survey over the regional NT aeromagnetic anomaly. The aim of the survey was to confirm the location of the regional aeromagnetic anomalies and to carry out a depth to source interpretation of the magnetic bodies. This resulted in nine high order magnetic anomalies which are not on the surrendered portion of the tenement. Subsequent drilling of magnetic anomalies and reconnaissance rock chip sampling and mapping was also conducted on the retained area of the tenement only and not relevant to this report. No ground disturbing exploration activity was under taken during 2008-2009 other than reconnaissance work and field checking of open file data due to a severe economic downturn and cessation of all exploration activities relating to molybdenum and tungsten mineralisation. The decreased potential for economic molybdenum and tungsten mineralisation together with the age of the tenement led to the southern half being surrendered at the end of Year 4. The Ultraviolet prospect is considered to be worthy of further trenching and reconnaissance drilling due to the presence of scheelite in magnetite skarn noted in the area in an old exploratory hand dug pit on the retained area of the tenement.
