An agglomeration of exploration licences which partly surrounds the Challenger gold deposit at distances of between 35 and 80 km is being explored for similar type economic lode gold mineralisation that may exist in buried Archaean bedrock relatively close to the surface. The region is crossed by conjugate NE-trending and NW- trending faults, clearly delineated by regional magnetic data, which are interpreted to have been active during intrusion of Hiltaba Suite granite bodies. A number of long-lived crustal scale shear zones cross the Archaean terrain, providing potential pathways for gold-bearing fluids. These shears are accompanied by abundant offset fault splays, a favoured trap site for the accumulation of mineralised fluids. It is also believed that the same aged volcanic flows of the Gawler Range Volcanic Domain could have acted as a seal, trapping mineralising fluids beneath them, to be released along these dilational fault structures to form large gold deposits. Marmota's exploration strategy is to try to detect as yet untested supergene gold dispersion haloes using geochemical methods, and then vector towards the source deposits via structural mapping and drilling. Exploration during the first project joint reporting year proceeded via ongoing surface geochemical sampling of calcrete in 8 target locations and the acquisition of ground geophysical surveys, followed by RC drilling of selected anomalies. A total of 3897 surface samples were assayed, 237 new gravity stations were read over a 200 m x 200 m grid at Widgety on EL 5195, accompanied ~46 line km of magnetometer readings made along 35 lines at 200 m or 100 m spacings, and 29 RC holes for 1643 m were drilled at Widgety and near Westpoint Hill on EL 5060. The best mineralised drillhole intercept revealed was 70 ppb Au from 30-33 m downhole in WRC009. During project Year 2, when additional licence acreage was added to the search area, 924 surface calcrete samples were assayed and 87 aircore holes for 4189 m were drilled. This work disclosed two significant gold occurrences on EL 5589 at Goshawk and Kingfisher. A best drillhole intercept of 12 m @ 14.4 g/t Au was made below 24 m hole depth in 17AT021 at Goshawk, including 4 m @ 40.2 g/t Au from 32 m. At Kingfisher a best result of 4 m @ 1 g/t was obtained in hole 17KI003. The Goshawk gold occurrence occupies weathered quartz-biotite-muscovite gneissic bedrock over a 500 m strike length, whereas at Kingfisher, where the extent of mineralisation is less well defined, the host rocks comprise both weathered mafic gneiss and weathered iron-rich BIF (to 37% Fe). Based on these incremental drilling successes, Marmota developed a new exploration model whereby it now recognised that significant mineralisation can be indicated by lower order calcrete anomalies due to the nature of cover, degree of weathering in bedrock and depth of burial. Therefore the company planned to conduct all of its new regional calcrete sampling on an 800 m spacing, with infill to be done around selected anomalies in the 5-10 ppb Au range. During project Year 3, activities comprised surface calcrete sampling (1479 samples assayed for 30 elements), vegetation biogeochemical sampling (415 plant samples assayed for 66 elements), acquisition of a 120.9 line km ground magnetic survey covering three target areas, the drilling of 50 RC holes for 3988 m plus 6 diamond cored holes for a total of 313.5 m (including 206.8 m cored), and the conduct of metallurgical gold extraction testwork involving 3 cyanide gold bottle rolls and performing a QUEMSCAN bulk mineralogical analysis on 2 ore samples. On Aurora Tank EL 5589, further significant gold intercepts were made at Goshawk prospect, and new targets were identified by the plant biogeochemical results. The known Goshawk mineralisation was extended both downdip and down plunge, to depths of >80 m. During project Year 4, activities comprised a continuation of plant biogeochemical sampling on ELs 5589 and 6166, the drilling of 31 RC holes for 3187 m on EL 5589 and the drilling of 12 RC holes for 1716 m on EL 6166, plus the drilling of 195 aircore holes for 3187 m on ELs 5589, 6166, 5799 and 6082; 61 of the latter holes were drilled to test eleven new targets. Holes put in at these targets were shallow, being designed to detect any secondary dispersion from an ore zone developed in the saprolite or saprock; however, the results obtained did not warrant follow-up. Sighter column leach tests were performed on minus 12.5 mm crushed remnants of drill cores recovered by the previous diamond drilling, and total gold recoveries of better than 75% were achieved, which implied that heap leaching might be a viable method of gold extraction for the Aurora Tank deposit.
