Kurundi Project GR-77, Combined annual report for the period 13 February 2008 to 12 February 2009, EL 23937 and EL 24995

Abstract

The Kurundi Project (GR-77) comprises tenements EL 23937 and EL 24995. The tenements are located approximately 400kms NNE of Alice Springs and 100km SE of Tennant Creek. The eastern portion of EL 23937 lies on the western edge of Epenarra Station, and EL 24995 lies on the western boundary of Kurundi Station. The Kurundi Project (GR-77) covers the contact between the western Georgina Basin and the Tennant Creek Inlier on the northern side of the Davenport Range. The regional basement rocks are Proterozoic (1870Ma) deepwater marine interbedded greywacke, siltstone and minor porphyritic felsic volcanics of the Warramunga Group which were moderately to tightly-folded about 1810Ma. The Warramunga Group is intruded by members of the Tennant Creek Supersuite. This includes the Hill of Leaders Granite (Pgb) which outcrops extensively in the northwest of the tenement area. It is a multi-phase, fractionated granite, characterized by large orthoclase phenocrysts up to +5cm in diameter. The Munadgee uranium mine is located on the western side of EL 23937. The primary Georgina Basin unit present within the project area is the near-basal Gum Ridge Formation which is known to contain phosphate. A ground gamma radiometric survey was completed in March-April, 2008 in the area of the historical Munadgee Mine, a ridge to the east of the mine and a radiometric anomaly 3.5kms to the southeast of Munadgee. Historical radiometric data from CR1979-0142 of downhole radiometric surveys and a ground radiometric survey across the Munadgee ridge were digitised from data in a report. Assay results for 49 RC samples were received. A ground magnetic survey was conducted in the area of the Munadgee Mine in May 2008. During the course of the year MCC 968 was re-mapped by the NT Government. This resulted in the location of the claim being shifted from a ridge 1km east of the Munadgee mine to where it was pegged on the ground overlying the mine area. Further re-processing work was done on existing aeromagnetic data. Geological mapping of the Munadgee ridge and the valley to the east was also conducted. Rehabilitation of the RC and AC drilling program completed in 2007, was performed in September, 2008. A rock chip program targeting phosphate in the eastern part of EL 23937 within the area underlain by the Georgina Basin sediments saw 35 samples taken. Additional digitising of NT water bore data and historical tenement reports was completed including RAB and vacuum, soil and rock chip sampling in the area of EL 23937. Additional data was collected from the area of the old Munadgee uranium mine. Follow up work is proposed to include diamond drilling. The phosphate potential of the eastern portion of EL 23937 has been examined by rock chip sampling, orientation trips to old drill sites and validation of mapped units, and remote sensing. Minor low-grade phosphate mineralisation was located. The Gum Ridge Formation in the east of EL 23937 is a potential host for significant phosphate mineralisation. The uranium potential of the immediate Munadgee Mine area remains untested due to access issues centred on Aboriginal sacred sites.
