Aditya Birla Minerals is primarily focused on copper production but holds copper exploration tenements around the existing Nifty and Mt Gordon operations, as well as at the Maroochydore Copper Project. Focusing on underground mining in Queensland and Western Australian copper mines, the company has continued to actively undertake near mine and regional exploration drilling programmes throughout 2012.
Since inception in 2003, Aditya Birla Minerals has concentrated on mine development, resource and reserve delineation drilling within and adjacent to current operations. The company has significantly increased its exploration activities at both sites, particularly at Mt Gordon copper mine in Queensland, Australia, where further major discoveries could have a major effect on the scale of the operation and annual copper output. In addition to copper exploration in Australia, Aditya Birla Minerals also plans to pursue exploration and development opportunities at an international level.
Advanced Queensland and Western Australian Exploration
Aditya Birla Minerals holds some 4400 sq. km of copper exploration tenements around the Birla Nifty Copper Operation (BNCO) in the Great Sandy Desert, WA and approximately 1300 sq.km in the Mt Gordon Copper Operation (MGO) located in the Mt Isa Block, QLD. In addition to these copper exploration tenements, the company holds exploration and mining rights to the Maroochydore Copper Project, located only 100km from the Nifty mine site. The tenements are actively explored using geological, geophysical, geochemical and structural modelling to guide drilling programmes in the search and discovery of economic copper deposits.
Birla Nifty Exploration
A structural, stratigraphic and geophysical study of the Nifty mine and near mine geological environment to identify high potential drilling targets for extensions of known resources or to locate new discoveries has been recently completed. Interpretation of Downhole Electromagnetic Survey (DHEM) results was also recently completed for 9 surface drillholes testing near mine targets developed from geophysical interpretation of CDI (conductivity depth image) and conductivity sections from VTEM data and detailed magnetic imaging. The interpretation has generated multiple conductive plates associated with most drillholes and an interpretation of these within the Nifty 3D resource model is currently in progress to refine and prioritise drilling targets derived from these.
A programme of approximately 4,500 metres of pre-collared surface diamond drilling has commenced incorporating targets from stratigraphic and structural studies, DHEM surveys and will also incorporate the results of a 31,000 line kilometre low level, high resolution aeromagnetic and radiometric survey that is now close to completion..
The Maroochydore copper Project is located at the western margin of the Great Sandy Desert approximately 100km south-east of the Nifty copper mine (Nifty), 100km south of the Telfer gold mine and some 450km south-east of the Port Hedland concentrate loading facility. The 2012 drilling programme, comprising 33 drill holes for 14,971 metres of pre-collared diamond drilling, commenced at the end of April 2012 and was completed in October. Drilling was undertaken over a 5km strike length and included 10,602 metres of diamond drilling at an average hole depth of approximately 453 metres. Stratabound copper sulphide mineralisation of low to medium grade tenor was located in almost all holes and was locally upgraded to narrow high grade lenses in highly deformed and strongly brecciated folded and faulted structural traps.
Mt Gordon Copper Exploration
The Mt Gordon Copper Project is located in northwest Queensland, approximately 120 km northeast of Mt Isa.
Mammoth North - The follow-up surface drilling programme completed at Mammoth North targeted a previous underground drill hole (UM783) that intersected 31.5m @ 1.11% Cu at a cut-off grade of 0.2% Cu and was also directed at testing for extensions to mineralisation between the top of the Mammoth deposit and surface, proximal to this hole. Four holes were completed for a total of 2068.20m. Assay results of these drill holes confirmed the extension of the mineralised structure up and down dip. This programme led to the announcement to ASX, dated 12 November 2012, of a maiden Inferred Resource of 10.12Mt @ 1.06%Cu.
Esperanza South - At Esperanza South the drilling program located the interpreted down dip extension of copper mineralisation that occurs along the regionally significant Mammoth Extended Fault. Drill hole SD529 intersected significant mineralisation approximately 200m below the base of currently known mineralisation as shown in the figure below.
