Annual and final report on EL 22413 Baiguridji River, for the period 18 May 2009 to 23 April 2010

Abstract

EL 22413 Baiguridji River was applied for by Rio Tinto Exploration Pty Limited (RTX) on 11 February 2000 and was granted on 18 May 2006. RTX is the sole manager and operator of this tenement. The original tenement application covered an area of 117km2 (35 sub blocks) of which only 66.9km2 (20 sub blocks) gained consent. The remainder of the application area did not gain consent, and was subsequently relinquished. In 2008, 50% of the granted tenement (10 blocks) was relinquished. The remaining 10 sub blocks were relinquished in full on the 23 April 2010. EL 22413 is located 150km southwest of Nhulunbuy, east Arnhem Land, and consequently is processed under the Aboriginal Land Rights Act 1975 (ALRA). EL 22413 covers part of the subtle plateaus south of the Frederick Hills, and east of the Mitchell Ranges. This area has undergone a similar geomorphological history to that of the Cato Plateau, which is a known area of bauxite mineralisation of similar style to the nearby world class Gove deposit. The area is also considered prospective for base metal mineralisation similar to that of McArthur River (HYC) in the McArthur Basin. Diamonds are a subsidiary target. This is the fourth Annual and Final report and describes the exploration completed during the fourth year of the tenement. Exploration included conducting 13 shallow hand auger drill sites of the low laterite surface to test for bauxite. The results were negative with no evidence of the bauxite profile being present. The tenement has been relinquished in full.
