St George mining Locates New Targets at Mt Alexander
THE DRILL SERGEANT: St George Mining (ASX: SGQ) received encouraging results from recently-completed regional EM surveys at the company’s Mt Alexander project in Western Australia.
St George Mining carried out the MLEM survey over a east-northeast corridor parallel to and one kilometre south of the Cathedrals Belt.
The survey identified a strong EM anomaly – Anomaly 11 –450m south of the intersection of this corridor with the northern extension of the Mt Alexander greenstone belt.
St George explained that this east-northeast feature was first recognised in high resolution magnetic data generated by an airborne magnetic survey it previously completed at Mt Alexander, adding that it may represent a primary transform fault that could host mineralised komatiitic ultramafics, similar to the Cathedrals Belt.
The MLEM survey modelled the EM plate for Anomaly 11 with dimensions of 113m by 91m and at a depth of 98m below surface.
The company has prioritised drill testing of this target for the next drill program at Mt Alexander.
The new high resolution magnetic data also identified the location of the Ida Fault within the Mt Alexander tenements.
St George believes the intersection of the Cathedrals Belt and Ida Fault could be an important geological location that could have acted as a first order regional control on mineralisation within the Mt Alexander tenements.
To confirm this theory, St George will carry out a high powered SAMSON EM survey over the western extension of the Cathedrals Belt including the area where these structures intersect, to search for any deep conductors that may represent massive sulphide accumulations.
“Geophysics has been an excellent exploration tool at Mt Alexander with EM surveys identifying numerous conductors in the Cathedrals Belt that have been drilled and confirmed as nickel-copper sulphide mineralisation,” St George Mining executive chairman John Prineas said in the company’s announcement to the Australian Securities Exchange.
“We are continuing to use reconnaissance geophysics in unexplored areas of the Mt Alexander project, and early results are encouraging.
“It is pleasing to see that as we advance prospects in the Cathedrals Belt, we also have very attractive exploration targets within the broader project area.”
