St George Mining Limited (ASX: SGQ) has announced new promising nickel targets at its flagship Mt Alexander project in Western Australia.
Several compelling targets were confirmed by the recent fixed loop electromagnetic (FLEM) survey near the interpreted granite/greenstone contact of the Mt Alexander Belt.
The targets included a large FLEM conductor – P1 – which is interpreted to be approximately 4km south of the high-grade Cathedrals Ni-Cu-PGE massive sulphide deposit located on the east-west Cathedrals Belt. P1 is modelled as an EM plate with the following parameters:
- conductivity of 7,650 Siemens with a late-time EM response
- dimensions of 400m x 200m
- located approximately 200m below surface
Nickel exploration is being carried out at Mt Alexander – where St George has already made four high-grade sulphide discoveries – in parallel with a maiden lithium exploration program.
St George, which is presenting at Paydirt’s Australian Nickel Conference in Perth this afternoon, has established a track record of successfully using electromagnetic surveys to identify targets that are highly prospective for nickel. The company is excited at the latest highly prospective nickel targets identified by the FLEM and looks forward to testing them with drilling later this quarter.
The dual-track exploration focus at Mt Alexander follows the identification in the September Quarter of potentially significant, visible lithium minerals in several outcropping pegmatite dykes within a 15km-long corridor on St George tenements. The first phase of pegmatite mapping and rock-chip sampling is almost complete and first assays from rock-chip samples submitted to the laboratory are expected next week.
“Initial results from the FLEM survey that commenced last week at Mt Alexander are very encouraging with a number of conductors confirmed in the area south of the Cathedrals Ni-Cu-PGE Belt,” executive chairman John Prineas said.
“The prospectivity of the key conductive anomaly identified by the earlier moving loop ARMIT EM survey has been upgraded. The FLEM data indicates a larger and more conductive anomaly, referred to as P1 that has a geophysical signature consistent with massive sulphides.
“This bedrock conductor is located within the interpreted area of the granite/greenstone contact south of Cathedrals and is a compelling nickel target.
“In addition, P1 occurs south of a large, distinctive seismic reflector with an interpreted source below the granite intrusion and bounded by faults that may be related to the Cathedrals massive sulphide mineralisation. The strong seismic reflector is also considered a high-priority drill target.
“The granite/greenstone contact has not previously been explored and we are delighted that our systematic exploration has identified new, high-priority nickel targets for drill testing.
“We look forward to an exciting drill program in Q4 2022 that will test both these new nickel targets as well as the emerging lithium prospects at Mt Alexander.”
