East Pilbara Lithium Tenements
E45/5821
E45/5821 is located to the north-east of the Wodgina greenstone belt, covering the Sisters Supersuite of the East Pilbara granite-greenstone terrane. In the tenement area, the Sisters Supersuite monzogranite is intruded by a number of north-south striking mafic dykes of the Black Range Dolerite. The tenement area has received minimal previous exploration with the only recorded work being stream sediment and reconnaissance rock chip sampling. Pegmatite was encountered in the southwest of the tenement, however no elevated lithium results were returned from the limited outcrop sampling. A number of pegmatite occurrences are located immediately north of the tenement, within the Sisters Supersuite monzogranite. Both anomalies are oriented NW-SE, tending into E45/5821.
E45/5879
E45/5879 covers basaltic volcanic, volcanoclastic and sedimentary rocks of the Fortescue Group. The tenement includes the historic Glen Herring gold and Sharks North copper-lead zinc mines. Sampling of conglomerate outcrop of 4 to 6 metres width during 1988 returned a maximum value of 11.2g/t Au over a zone 0.3m wide2 . Costean sampling of the same unit 2500 metres to the east of the tenement returned values to 4.15g/t Au. Follow up RC drill testing failed to return any significant gold values. Only one portion of the three kilometre strike extent of the conglomerate unit within E45/5879 has been tested to date.
E45/5717
E45/5717 covers a structurally complex area comprising sediments, felsic volcanics, and mafic to ultramafic units of the Pilbara and De Grey Supergroups. The tenement hosts minor historic gold workings. The only previous work undertaken was regional-scale stream sediment sampling.
E45/6088
E45/6088 covers Numbana Monzogranite, a member of the Split Rock Supersuite that hosts a number of known Sn, Ta and Li occurrences including the Shaw River Project mineralisation and the Pippingarra Lithium Project. The Numbana Monzogranite has been mapped as a medium- to coarse-grained porphyritic monzogranite containing localised garnet-bearing pegmatite and granite dykes. To the south of E45/6088 the Numbana Monzogranite hosts historic tantalum mines including the Stein, Grayden, Northern Minerals 2 and Mt Francisco/Sherlock and Parker mines and the Turner River tin alluvial workings. There is no known previous exploration within E45/6088.
