Annual report EL 30002 Walbiri South Ngalia Regional Project period ending 8 April 2015

Abstract

EME has remained focused on exploration within its 100 percent owned Ngalia tenements despite the poor market conditions and downturn in the uranium sector. Exploration for the reporting period 9 April 2014 to 8 April 2015 was largely directed at regional data acquisition from a high resolution (50m-spaced) helicopter airborne magnetic and radiometric surveys flown in November to December 2014. The target areas flown comprised four separate areas on ELs 24451, 24453 and 24463 which partly overlapped other EME tenements ELR 41, ELR 45, EL 30144, EL 30002 and EL 30004. Following receipt of final data products in February-March 2015 and interpretation of the imagery, key outcrops were investigated on the ground within EL 30002. An area of interest south of the historical Walbiri Prospect including the eaten part of EL 30002 was investigated for surface mineralisation. The helicopter magnetic-radiometric survey allowed uranium-prospective Mount Eclipse sandstone units to be traced in folded strata south of the historical Walbiri Prospect and onto EL 30002. The outcrops visited were along NE striking ridges dipping moderately N-NW which form the south limb of the Nama Syncline and north limb of the Bean Tree Anticline. The outcropping sandstone was mostly oxidised but some bleached and weathered zones indicated by secondary limonitisation were common. Overall the outcrops were dominated by interbedded siliceous, coarse-grained sandstone with immature arkosic beds and sequences. Outcropping shales were rare but the steep nature of the topography and large amounts of colluvium concealed finer sequences. The highest RadEye scintillometer reading was 60-75 cps from a thin (less than 1m thick) micaceous siltstone unit. Portable Niton XRF measurements of the sample revealed gamma anomalism as due to thorium, however, elevated Cr and V values were recorded, similar to the Walbiri deposit. Although no uranium mineralisation was found at surface, the facies encountered along traverses Ws and Ws1 appear favourable as hosts to uranium mineralisation.
