    St George Mining’s Mt Alexander project provides further high-grade drill targets

    St George Mining Limited (ASX: SGQ) has announced highly encouraging results from the ongoing exploration programmes at the Mt Alexander Project in the north-eastern Goldfields, WA.

    The company reported that the exploration programmes have generated additional strong targets for the discovery of more nickel-copper sulphides at Mt Alexander project.

    SGQ announced that the soil survey at the Fish Hook Prospect identified a nickel soil anomaly with a strike of 700m.

    The company reported that extensive geophysical surveys are being launched across the Cathedrals Belt to identify further nickel-copper sulphide targets. SGQ said that MLEM survey would be completed at the Bullets, West End, and Fish Hook Prospects.

    The company reported that the drilling of EM conductors continues, with hole MAD172 underway to test the first of seven EM conductors identified so far by the DHEM surveys in the recently completed deep stratigraphic holes along the Cathedrals Belt.

    Mt Alexander project

    The Mt Alexander Project is located 120km south-southwest of the Agnew-Wiluna belt which hosts numerous world class nickel deposits.

    The project is comprised of five granted Exploration Licences, E29/638, E29/548, E29/954, E29/962, and E29/972. The project contains advanced prospects like Investigators (MAD60), Stricklands (MAD71), and Cathedrals (MAD56), which are located on E29/638. 

    Mt Alexander has two stand-out EM anomalies named Radar and Bullets prospects. Other unexplored areas in Mt Alexander project includes the West End and Fish Hook prospects.

    The Fish Hook Prospect covers an interpreted eastern extension of the east-west oriented Cathedrals Belt located within Exploration Licence 29/954.

    Exploration programmes at Mt Alexander

    The company reported that the exploration programmes at Mt Alexander project continue to successfully scope out the scale of the large mineral system at the Cathedrals Belt.

    Soil survey at Fish Hook prospect

    It may be noted that a trial soil survey was completed at Fish Hook earlier this year and returned highly anomalous geochemical values for nickel, copper, and chromium – indicative of an ultramafic with nickel-copper sulphides.

    A comprehensive soil survey was subsequently completed across the 8km east-west strike of the Fish Hook Prospect, with a total of 1,260 samples collected on 200m spaced lines with 20m sample spacing.

    SGQ announced that the soil survey at the Fish Hook Prospect identified a nickel soil anomaly with a strike of 700m.

    The company reported that 1,260 soil samples from Fish Hook returned assays that include anomalous values indicative of ultramafic rocks below surface.

    The company said that most highly anomalous assays connect in a linear trend consistent with the interpreted eastern extension of the mineralised Cathedrals ultramafic.

    The company said that the large nickel anomaly and surrounding areas are considered prospective for nickel-copper sulphide mineralisation and will now be screened by an MLEM survey to identify drill targets.

    St George Mining reported that surface moving loop electromagnetic (MLEM) survey would be completed at Fish Hook ahead of the maiden drill programme.

    MLEM survey

    The company reported that extensive geophysical surveys are being launched across the Cathedrals Belt to identify further nickel-copper sulphide targets.

    SGQ reported that surface moving loop electromagnetic (MLEM) survey would be completed at the Bullets, West End, Stricklands, and Fish Hook Prospects.

    The company said that high temperature SQUID sensor would be used in the MLEM survey to minimise potential interference by conductive cover and to optimise depth of penetration.

    Seismic survey

    St George Mining reported that an inaugural seismic survey has been planned for the Cathedrals Belt to investigate the structures associated with the mafic-ultramafic intrusives that host nickel-copper sulphides.

    The company said that further details of the seismic survey will be announced once the planning of the survey is complete.

    Drilling of EM conductors

    The company reported that the drilling of EM conductors continues. The company said that the holes MAD169, MAD170, and MAD171 were completed since 29 October 2019. All three holes were deep stratigraphic holes at the Investigators Prospect

    SGQ said that the diamond drilling of hole MAD172 is currently underway. This is being done to test the first of seven electromagnetic (EM) conductors identified so far by the downhole EM (DHEM) surveys in the recently completed deep stratigraphic holes along the Cathedrals Belt.

    The company said that the target EM plate is modelled with conductivity of 25,000 Siemens and at a depth of 260m downhole – the deepest conductor drilled to date at the Cathedrals Belt.

    The company reported that a DHEM survey will be completed in all three holes to search for further mineralisation around the holes.

    Next steps

    The company said that further exploration will be planned based on ongoing drill results, geophysical surveys and geological assessment of prospectivity.

    Management comments

    St George Mining’s Executive Chairman, John Prineas said: “Our systematic exploration programmes continue to successfully scope out the scale of the large mineral system at the Cathedrals Belt.

    The soil survey results at Fish Hook are very encouraging because they have identified a new anomalous trend 5km east of the known nickel-copper mineralisation at the Cathedrals Belt. This is an area that webelieve is prospective for a greenfields discovery.

    We are also pleased to be rolling out a new moving loop EM survey at Fish Hook and other unexplored areas of the Cathedrals Belt where there is strong potential to generate more EM targets for drill testing.

    The seismic survey is another exciting initiative with the potential to deliver an exploration breakthrough that could assist us to better understand the controls and distribution of the high-grade mineralisation along the Belt.”
