Yundurbulu Project EL 31303 Annual Report for the period 6 February 2017 to 5 February 2018

Abstract

No work was carried out on EL 31303 during the reporting year. Planning for the year 2 work program has been finalised and is to begin in the second half of 2018. The 2018 work program will incorporate the year 1 program expenditures. The focus of the initial work in EL 31303 is to identify prospective areas for LCT style pegmatites that may contain Tin, Tantalum, Niobium, Caesium and Lithium. Pegmatite swarms have been identified using satellite imagery in conjunction with the Reynolds Range 5453 100K geological map. These pegmatite swarms are localised in an area within the EL 31303 boundaries and are part of the Napperby pegmatite district as shown in the 2005 KM Frater report titled 'Tin-Tantalum pegmatite mineralisation of the Northern Territory'. The Mt Stafford 1 and Mt Stafford 2 Tin occurrences are relatively close to the target pegmatites in EL 31303. The pegmatite swarm area is adjacent to the ga granite of the Anmatjira range. This intrusive is described as the Anmatjira Orthogneiss with minerology and texture shown as a biotite granite/granodiorite, equigranular/seriate porphrytic or K-Feldspar megacrystic with a foliated structure (aged 1814+/- 6Ma). The Orthogneiss outcrops the entire length of the Anmatjira range and weathers to a characteristic 'Rotten Stone' in the northern extremity of the Yundurbulu Range. The 2018 initial work, to be carried out, in the second half of 2018 will encompass a prospectivity study and sampling of not only the Pegmatites but also the mafic rocks around the Anmatjira and Yundurbulu ranges, whilst looking for prospective high grade metamorphic structures around the granites.
