Annual Report for EL 9452 Manyalluluk Project

Abstract

This report describes exploration work undertaken on the Manyalluluk Project during the first year of tenure. The tenement was granted on 5 May 2004 for an initial period of six years. Field activities during the reporting period consisted of eight days of helicopter assisted sampling, radiometric anomaly follow-up, reconnaissance and familiarisation of project geology. Airborne magnetic and radiometric surveys and a hyperspectral survey have been flown over the project area, with the latter conducted only over the eastern portion of tenement. Follow-up of radiometric anomalies identified from the airborne radiometric survey identified anomalous U in a minor number of samples associated with clay alteration and structural disruption within the Grace Creek Granite and Hindrance Creek Sandstone. The majority of radiometric anomalies were observed to be associated with the mafic volcanic units of the Katherine River Group, related to near surface weathering effects and scavenging of U from surficial sources, and do not require any further work. Further work is recommended for the areas of identified anomalous U, and would consist of low impact, sampling and mapping. Future work will be aimed at generating a regional sampling coverage of the sandstone terrain to provide baseline signatures for lithogeochemistry and recognition of any possible broad alteration within the sandstone covered portions of the tenement, and an evaluation of the targets defined from the hyperspectral clay interpretation.
