Earlier explorers have undertaken aeromagnetic and gravity (geophysical) surveys,
geological mapping and rock chip sampling, with one pass of drilling within
Mount Ridley’s Project.
Mapping identified large areas of haematite enrichment and rock chips
taken during Mount Ridley’s geological reconnaissance trip returned high grade
iron assays, which support the prospectivity of the project. Between 2007 and 2013 iron exploration was undertaken by Crosslands Resources Pty Ltd, which completed mapping, some limited rock chip sampling and a small RC drilling programme.
Mapping and rock chip sampling highlighted the Wilgie Mia formation as a primary target. The Wilgie Mia formation shows well developed zones of goethite or haematite development at surface for much of the 10km
strike-length (and much of the overall 60km strike length). SinoSteels Beebyn Deposit and Fenix’s Iron
Ridge Project are both hosted within the Wilgie Mia Formation.
The Project also includes the prospective Madoonga Beds, where a five-kilometre-long and up to 75 metres wide anomalous goethitic zone coincides with a stacked geophysical anomaly.
Sinosteel’s Madoonga Deposit Geological mapping has also identified other target for goethite and hematite mineralisation for further investigation.
Mapping also identified broad areas of pisolitic channel iron deposits (“CID” on the geological maps) and detrital iron deposits (“DID”) that require investigative drilling.
The only RC drilling, completed by Crosslands, was situated on the north-western banded iron formations, and did not apparently target DSO haematite mineralisation.
