Aurumin Limited announced mapping and Ultrafine soil sampling is currently underway across Aurumin's Greater Sandstone Project. The program is designed to aid in the assessment of the Aurumin's Greater Sandstone Project, including new tenements, with samples collected to support mapping, interpretation and target generation. The soil samplingprogram is being conducted using Ultrafine soil geochemistry and is designed to provide systematic levelled geochemical coverage across whole tenements. The portion of the programme covering Aurumin's new tenement E57/1140 is 2/3 complete, on a 100m x 200m spacing, with sampling ongoing andcurrently collected samples submitted to the lab for analysis. Aurumin' newly acquired tenement E57/1140 is located on the north-western flank of the Sandstone Greenstone Belt. The geology is dominated by mafic rocks, predominantly basalt, gabbro and lesser ultramafic as well as narrow sedimentary units including banded iron and minor shales. The stratigraphy of the belt is broadly NNEstriking through the southern half of the tenements but then folds through 40 degrees to strike ENE through the top of the Sandstone Greenstone Belt. The Archean stratigraphy is crosscut with what is inferred to be Proterozoic dykes. A portion of the tenements are covered by Cainozoic alluvium. Gold deposits in the Sandstone Greenstone Belt exhibit strong structural controls, with higher grade mineralisation typically observed where structures intersect stratigraphy. The stratigraphic domains in the new tenements
package are considered potential hosts with all the equivalent stratigraphy's that host gold deposits in the Sandstone Greenstone Belt. The area is relatively lightly explored and historic data is limited over the tenement. Existing geochemical data sets are essentially gold only with partial coverage that includes arsenic. Localised surveys have been completed by multiple companies and which have held tenure over an extended period, however large parts of the tenement remain un-sampled. A desktop review of the historical geochemical and geophysical data sets has presented several initial areas of interest, and initial observations during mapping and sampling have identified several areas of locally intense foliated and folded mafic and BIF units coinciding with geophysical and/or geochemical signatures. Faults and structures hosting quartz showing long lived and episodic activity have been identified, along with in-situ quartz vein arrays adjacent to and up-slope of areas of transported laterite recently worked by prospectors. The overall work programme is designed to systematically cover the majority of Aurumin's Greater Sandstone Project, which includes granted tenements and tenement applications with Ultrafine soil geochemistry. This programme has commenced with coverage of tenement E57/1140. Ultrafine soil geochemistry targets the <2 ¦m size fraction within the same soil horizon as conventional soilsampling, a nominal sample depth of 25 cm. The CSIRO developed this method to help see through shallow to moderate cover. By taking such fine fraction the method looks to reduce the nugget effect while also increasing the signal to background ratio, providing more resolution in the bottom end towards the detection limit which may have potential in identifying subtle soil anomalies. A total of 49 elements are analysed. Most of the sampling covers areas previously sparsely tested or untested by either soil sampling or reconnaissance drilling. Samples will be acquired to test magnetic anomalies and interpreted structural positions, to characterise prospective lithologies, test anomalism indicated by historical datasets and areas acquire new data where no previous sampling has been completed.
