Petratherm Limited announced update on a soil geochemical sampling program, which has defined six high tenor arsenic (As) soil anomalies over the eastern portion of the Yuengroon Gold Project. Yuengroon (EL6897) is a large licence area of 683 km2 over a portion of the Bendigo Zone, covering the historic northern Wedderburn Goldfield and extends westwards over several important historical gold occurrences. The tenement area is blanketed mostly by shallow cover sediment concealing the prospective basement rocks and as a consequence has only been lightly explored. Arsenic anomalism in soil is derived from the breakdown of the sulphide mineral arsenopyrite which is found to occur with gold mineralisation in the underlying bedrock. It is principal path finder element used to locate primary gold mineralisation in the Victorian Goldfields. To date 1248 samples have been collected over a regular grid and analysed for As content using a portable handheld XRF. The surveys were undertaken over areas of shallow cover beyond the limits of historical shallow mining. This work has identified several coherent As anomalies of considerable magnitude and area extent. Typically, arsenic values in excess of 50 ppm are considered anomalous warranting further investigation. Each of the new targets defined have coherent As trends well in excess of 100 ppm extending for several hundred metres and include several exceptionally high As values. Shellback Prospects - The north eastern portion of the survey area has identified 3 prominent As trends and a fourth zone to the South which is a likely extension of this trend (Shellback Extended). The northern prospects trend up to 1 kilometre in length, with strong anomalies at the northern and southern end separated by a saddle (Mosquito Creek) which may be masking the As trend through this middle area. South of these anomalies, the Shellback Extended trend to the south has been identified and records a peak As value of 3089 ppm and may link up to the northern areas through the cover of an unnamed creek. On the western side of the survey area two prominent As targets have been identified, and have been termed the Peep O'Day and Lincoln Reef Extension Prospects. The Lincoln/Peep O'Day trend is 1.4 kilometres long. South of this trend the historic Lincoln Reef, line of workings which extend approximately 600 metres in length occur and comprise a series of shallow shafts sunk to the water table, at about 20 metres depth. The Lincoln line of workings have not undergone any modern systematic exploration and have never been drill tested.
