Outback Goldfields Corp. updated on exploration activities at its Yeungroon gold property located in central Victoria, Australia. Significant air-core drill program completed: Over 9,300 meters in 590 holes were completed across the property with two main objectives: Expand the 600 meter long, open-ended, near-surface arsenic geochemical anomaly south of the Golden Jacket mine to the north and northeast; and, Test numerous priority geophysical targets on the western side of the property along trend from the Moondyne prospect.

Shallow air-core holes were drilled on a grid pattern to the north and the northeast of the Golden Jacket Mine and along linear roadside traverses, perpendicular to the regional structural setting, covering the western side of the property. The highly portable air-core drill rig was used to sample and map the top of bedrock below cover. The air-core drill program was designed to build on encouraging results from a large grid-based, top of bedrock sampling rotary air-blast (RAB) drill program, and a short diamond drill program.

A footprint of approximately 4.4 square kilometers was covered in the Golden Jacket Grid and 8.5 kilometers of road-side traverse were covered on the western side of the property. Rock-chip samples from the drilling are being analysed daily using a tailored portable Xray fluorescence spectrometer (pXRF) workflow to measure elemental concentrations from prepared sample mounts as well as QA/QC samples. The focus for these analyses is pathfinder element geochemical concentrations (e.g., arsenic).

Portable XRF analyses are ongoing and anomalous samples will be sent to the lab for fire assay gold analyses and results will be reported once received and compiled. The relationship between gold mineralization and disseminated arsenopyrite and high-arsenic contents in host rocks peripheral to gold-bearing quartz reefs is well established throughout the Victorian Goldfields (e.g., Arne et al., 2008) and has been used to focus exploration and vector to high-grade mineralization. Using the pXRF has allowed the technical team to streamline the analyses and make informed exploration decisions in the field based on a key suite of pathfinder elements.

The 698 km2 Yeungroon property is transected by the north-trending, crustal-scale Avoca fault, which separates the western Stawell zone from the Eastern Bendigo zone. The western side of the Yeungroon property contains the historic Golden Jacket hard-rock reef mine associated with the regional-scale, northwest-trending Golden Jacket fault. Historical mining records indicate the Golden Jacket mine produced quartz-rich ore with grades of up to 250 grams per tonne gold (Bibby and More, 1998), however, the vertical and lateral extent of mineralization remains unknown.

The eastern side of the project is underlain by Ordovician rocks of the Castlemaine group and comprises the northern extent of the Wedderburn Goldfield, where numerous small-scale, historical alluvial and hard-rock mines are located.
