Barrow Creek EL 28521 Final Report for the period 28 October 2011 to 27 October 2019

Abstract

EL 28521 'Barrow Creek' is located in a region of varied and complex geology, which has led to a variety of mineral deposit types occurring and therefore an increased prospectivity. Of note are the historic Home of Bullion mine (Cu-Pb-Zn) and Prospect D (Cu-Ni). Several gold and gold-copper occurrences are also known as are pegmatite related occurrences of Sn-Ta-W and muscovite mica. The licence is underlain by lower proterozoic basement. Sedimentary rocks of the Georgina Basin overlie the basement. Numerous granites of varying composition are present as are mafic intrusives. Results from a regional stream sediment (SSED) sampling program in 2013 revealed gold anomalism in the Osborne Ranges. A follow up rock chip sampling program completed in September 2013 confirming the gold anomalism seen in the SSED sampling. An Air Core and RC drill program commenced on 6th December, 2013. A total of 2048 metres were drilled - 1619m Air Core in 27 holes and 429m RC in 14 holes. Drilling results were received in 2 batches in February and May of 2014. The Taylor Creek Traverse showed promising anomalism along the whole drill traverse (see Table 3). Drill traverses on the Osborne Range were cut short due to weather with only 14 holes completed. Results confirmed the presence of a silicification front from a local intruded granitic body. And it seemded that the Au is likely shedding from more elevated areas than what was drilled. A geophysical Mag. & Rad. airborne survey of 2276.9 line km covering the whole tenement was undertaken in March 2015 and interpretation report was then completed. To have a better understanding of the anomalies and work out the further exploration program, an additional assays of 332 samples collected from 16 drilling holes were completed in July 2015. To review the potential of other commodities, the geologist re-studied previous data and concluded a revised report in 2016. A drilling programme of four diamond holes and analysis of samples was completed by the tenement holder in 2017. To follow up the results of pXRF scanning, AMR approved an assay programme on half core intervals and the geologist complete a comprehensive report in 2018. Although there're potential targets for further exploration based on the interpretation and analysis of the available data obtained from previous exploration, after comprehensive assessment by the geologist and analysis of the future market of resource industry, AMR decided to surrender the tenement by not renew further, as the potential of this tenement was deemed not meet the company's strategy.
