The Mount Short tenement E74/651 secures a 50km2 area of the Ravensthorpe Greenstone Belt, prospective for volcanogenic massive sulphides (VMS), nickel massive sulphides and structurally controlled gold mineralisation. Ultramafics of the Ravensthorpe Greenstone Belt alternate with metasediments and banded iron formation units, all disrupted by north-west trending thrust faults, interpreted as conduits to mineralisation. North east to east-west striking dyke swarms crosscut the Archean granite and greenstone units.
A total of 246 holes were historically drilled, mostly shallow air core (50 holes) and rotary air blast (RAB – 171 holes) designed to penetrate the regolith. Anax will focus on reviewing the 10 deep diamond drill holes and 15 RC holes drilled by Traka Resources during their tenure from 2005 to 2017.
GSWA 1:500k Geology and Historical Drilling
The very limited outcrop and agricultural land use limits surface exploration to seasonal soil sampling. In this environment, mobile metal ion (partial) analysis of soil samples is proposed for future soil surveys to define geochemical anomalism across the tenure. Historical soil sampling open file results are available for the south eastern corner of the tenure and this data will be reviewed in conjunction with drilling data.
Traka conducted a detailed aeromagnetic survey and a ground EM survey in 2010, defining a number of EM anomalies as illustrated in the figures below. Historical drilling has targeted these anomalies and a review of drill logs and available drill core will highlight whether coincident magnetic and electromagnetic anomalies have been adequately investigated. Reinterpretation of these historical geophysical surveys will assist with depth targeting for Aurora’s ongoing exploration.
