THE DRILL SERGEANT: St George Mining (ASX: SGQ) has kicked off a deep search FLEM survey at the company’s Mt Alexander project in Western Australia.
The new deep search EM survey will cover the 3.5 kilometre strike length of the Cathedrals Belt where St George discovered massive nickel‐copper sulphides during the two drill programs it carried out earlier this year.
St George has drill nineteen diamond drill holes in the Cathedrals Belt that have intersected high-grade nickel‐copper sulphides at depths ranging from 25m to 170m from surface.
The company outlined the primary objective of the high powered FLEM survey will be to detect any deep conductors in the Cathedrals Belt below the depth of detection of previous EM surveys.
The new survey will also assist to define extensions of known mineralisation as well as any other conductors that may not have been detected by previous EM surveys due to system limitations.
The FLEM survey will use the deep penetrating SAMSON system developed by GAP Geophysics, which employs a very powerful transmitter that can deliver twice the depth penetration typically achieved by the conventional EM surveys undertaken at the Cathedrals Belt to date.
“We are very pleased to have commenced the first ever deep search EM survey at the Cathedrals Belt,” St George Mining executive chairman, John Prineas said in the company’s announcement to the Australian Securities Exchange.
“With every conductor drilled in this Belt confirmed as nickel‐copper sulphides, we know that this is a highly mineralised Belt where EM targeting works.
“The deep search survey is exploring areas of the Belt not yet tested and has the potential to deliver an important exploration breakthrough.”
