Growth-focused Western Australian nickel company St George Mining Limited (ASX: SGQ) has announced another significant target for nickel-copper sulphides identified from the seismic survey recently completed at its flagship high-grade Mt Alexander Project, located in the north-eastern Goldfields.
Modelling and interpretation of the seismic survey data has identified a new, large target – named S2 – in an underexplored intrusive structure located to the north, and parallel to, the highly mineralised Cathedrals Belt. S2 has a dip extent of more than 400m commencing from about 350m below surface.
The seismic properties of S2 are consistent with those of the new, large target (named S1) identified by the seismic survey over the Cathedrals Belt and announced last week.
S2 is rated as a priority target for the potential discovery of a large-scale nickel-copper-platinum group elements deposit and will be drilled in the next diamond drilling program, scheduled to commence in late January.
“Our first-ever seismic survey at Mt Alexander continues to deliver strong results with another outstanding new target for a potential massive sulphide deposit,” St George executive chairman John Prineas said.
“The north-south seismic lines completed at Mt Alexander straddled the Cathedrals Belt and stretched to the north into our 100%-owned Exploration Licence 29/548, where an underexplored east-west oriented structure – the Transits Belt – has been identified by shallow drilling. Importantly, Cathedrals Belt style host lithologies were also confirmed in the drilling.
“The seismic data has mapped the Transits Belt structure as dipping to the north, similar to the highly mineralised intrusive-host structure in the Cathedrals Belt to the south. “S2 – the new, large target identified in the Transits Belt – has the same seismic properties as S1 in the Cathedrals Belt and just like S1 is interpreted to be a target for massive nickel-copper sulphides.
“We are very excited to have two robust targets lined up for immediate drilling in our 2022 diamond drill programme.”
