dc.description.abstract | During the current reporting period a total of 9 rock chip samples were collected throughout the Licence and sent for geochemical processing. Previous explorers have likened the potential type of mineralisation of the area as resembling Sandstone Hosted Pb-Zn similar to the Laisvaal deposits of Sweden. This is unlikely as mineralisation within the prospect is hosted in dolomitic siltstones and mudstones. Mineralisation within the prospect appears to most closely resemble a Mississippi Valley Type (MVT) deposit model. This is because of its location within a stable cratonic basin, similar element ratios to other MVTs, mild deformation of host rocks, dissolution of dolomitic rocks, and regional and local scale structural features. However, the majority of MVT deposits occur in rocks younger than about 550Ma; the host Dook Creek Formation being approximately 1.3Ma, suggesting the prospect may be a hybrid MVT. Given the relatively well defined extent of outcropping mineralisation, ground based geophysical surveys should be the next exploration step. However, extensive silicification of the Dook Creek Formation may reduce the effectiveness of any geophysical survey. The most suitable methods would be gravity and inductive polarisation (IP). A gravity survey could distinguish dense sulphide mineralisation from the surrounding host of less dense unmineralised silificified dolomites and sandstones; having previously been used to detect MVT deposits. Additional in-house ground magnetic and electromagnetic surveys may also be undertaken to assist with interpretation of geological and gravity data. | en_US |
