Abstract: | Enigma Mining Ltd is a wholly owned subsidiary of TNG Ltd and holds all exploration licences in the prospect area. TNG Ltd, as operator, has established the presence of a large magnetite rich gabbro. This is defined by a zone of higher magnetic susceptibility surrounding a circular feature of lower susceptibility. This was thought to represent the top portion of a layered mafic intrusion. The circular feature may represent the magma chamber or feeder channel. The aim of this programme was to confirm the presence and nature of a layered intrusion and assess whether there was any potential for magmatic base metal and PGE mineralisation at depth. S saturated mafic-ultramafic intrusions of the Western Arunta province have been noted to have potential for orthomagmatic Ni-Cu-Co sulphide associations (Hoatson 2001). TNG proposed two deep diamond drillholes to test this concept, provide confirmation of a layered intrusive and using geochemical analysis, petrology and geophysics to ascertain the potential for magmatic sulphides. Confirmation of this would establish an exciting new exploration area. The project was called the Stirling Deeps Project. TNG completed a small diamond drilling programme between 28 October - 21 November 2009 to provide information on the nature and extent of a potential layered mafic intrusion in the prospective Western Arunta province. Two diamond drillholes were completed for 691.7 metres. SDDD001 and SDDD002 both intersected olivine gabbro but did not confirm the presence of a layered mafic intrusion in the area. Follow up drilling programmes are required to further test this theory. All work was completed to a high standard in time and on budget. |
