The AIM-listed explorer called the study “an important element in the determination of high-profile drill targets, enabling the rapid assessment of the potential for gold mineralisation”.
Results showed the depths to magnetic sources are shallowest in the western half of the Windidda project area.
A further magnetic and mineralised gold trend, which was drilled in a previous project known as Bermuda, to the south of Windidda, was also found to jut into one of the new exploration licence applications.
ECR began a survey of airborne and ground geophysics data in April over an area of 1,600sq km in the Yilgarn Craton at Windidda.
The aim of the work was to process and interpret available airborne magnetic and ground gravity data to determine the scope of any gold mineralisation.
Chief executive Craig Brown called the results “most encouraging” and said they “demonstrate real potential for the discovery of gold mineralisation hosted in under-cover Archaean greenstones”.
Brown added: “The under-cover greenstone exploration model has been successfully tested to date by Greatland Gold at its Ernest Giles project located approximately 125km east of ECR’s Windidda gold project.”
