Title: | Annual Report for EL 24305 for the period 5 November 2015 to 4 November 2016, Walker River |
Title Holder / Company: | Rio Tinto Exploration DPG Resources |
Report id: | CR2016-0656 |
Tenure: | EL24305 |
Year: | 2017 |
Author: | Duncan, G |
Abstract: | EL 24305 is a part of the original EL 385 application made in 1972 by CRA Exploration Pty Limited (CRAE) the precursor to Rio Tinto Exploration (RTX) the current holder. Partial consent of EL 385 resulted in the granting of two separate licences (EL's 385 & 24304) in June 2004. EL 24305, an application in moratorium resulting from EL 385, was granted on the 5th of November, 2015. The tenement is located approximately 180 km south-west of Nhulunbuy, and 80 km north of Numbulwar in south east Arnhem Land and on Aboriginal Land Rights Act 1975 (ALRA) land managed by the Northern Land Council (NLC). The tenement is considered prospective for base metal mineralisation, similar to that at McArthur River (HYC) in the McArthur Basin. In January 2014 Rio Tinto Exploration and DPG Resources Australia Pty Ltd entered into an Earn In and Joint Venture Agreement with DPG managing the tenements. This applies to EL 24305 as well as EL 385, 23565 and 30952, and ELA, 844, 5561, 24305, 27919, 27920, 30953, 30954, 30955, 30956, 30957 and 30958. Work conducted during the year was conducted in conjunction with work on EL 385 and included, World View 2 Satellite Imagery purchase and processing, a detailed airborne magnetics and radiometric survey, soil and rock geochemical sampling, a dipole-dipole IP survey, a ground gravity survey and a drilling program. The target on EL 24305 and adjoining tenements is SEDEX style base metal mineralisation. The Balbirini Dolostone has 'gossanous' outcrops which are silicified and ferruginous, samples of which taken in the early 1970's reported elevated lead values to 2.7%. Soil and rock chip sampling show the initial target area has encouraging surface geochemistry with soil and chip sample results of anomalous lead, including a 1400m long contour of plus 500ppm lead with a maximum of 2800ppm lead. Rock chips have confirmed the soil results with values as high as 1.8% lead. Drill testing which finished in November 2016 has better defined geology of the Balbirini - Jalma - Coast range SSt package. Detailed logging, analysis of the multi element geochemistry, petrology and microprobe analysis will be undertaken in early 2017 to direct the coming field program and provide vectors for further exploration of the granted tenements and the planning of work for the EL Application areas. |
