Seventh Annual and Final Report Numery EL 31251 for the Period 23 November 2016 to 09 November 2023

Abstract

EL 31251 was granted in November 2016. Partial relinquishments were effected in 2019, 2020 and 2022. Primary target commodities are base metals, gold, nickel, cobalt, PGE's, Mo and W. There are no mines or deposits within the tenement area. EL 31251 covers the eastern end of the mooted Illogwa IOCG belt first recognised by NTGS in 2010 and comprehensively worked by Mithril until 2014. They discovered numerous cropping out copper in granite prospects often associated with zones of regional hematite-magnetite-fluorite-silicic quartz vein-hosted alteration trending east southeast over a strike length of 50km within a belt over 5km wide. Within EL 31251 seven copper prospects coincident with copper in soil anomalies +/- gravity/magnetic responses crop out over a 6km x 4km area. On the basis of the previous exploration results, it was determined that potential exists for IOCG-type deposits associated with altered granites or skarn deposits in Arunta Complex, and sediment-hosted base metals in the Amadeus Basin. After review and re-compilation of past exploration results, a ground gravity survey comprising 1060 stations was commissioned in 2018. The area surveyed is 25 square kilometres covering the Goldmember, Mini Me, MiniMe West and EL Gordo prospects defined by Mithril. The survey also covered an un-named prospect defined by Mithril comprising a substantial soil sample grid with anomalous Cu, Ni and Co and partly coincident with a magnetic complex. Gempart called this prospect 'Donald'. Nominal gravity reading interval was 200 x 200 metres, with infill to 100 x 25 metres. Low-order localised gravity anomalies occur at or adjacent to the Goldmember, MiniMe West and Donald prospects. Detailed modelling of the new gravity data and aeromagnetic data from the Mithril helimag survey was completed to define possible drillsites at the three prospects. Field work at the Donald prospect included reconnaissance mapping and pXRF readings. Outcrop is mostly dolerite. Elevated readings of base metals, vanadium and cobalt were observed. Best result was 193ppm Cu on a dolerite near the centre of the gravity anomaly. The elevated readings were scattered and often not coherent. No field work was undertaken in 2020 due to Covid-19 restrictions. Office studies included collation and re-plotting of 491 rock chip sample lithological descriptions and assay results collected by Mithril from 2009-14. Work during the fifth year comprised acquisition of AEM (VTEM) data at 300 metre line spacing over a small area in the southeast corner of EL 31251, where surface sampling by previous explorers defined elevated copper in surface samples. The VTEM survey comprised 34.5 line km over an area of 9.6 square km. No anomalies of interest were identified in the VTEM data.
