St George Mining hits more nickel-copper sulphide at Mt Alexander
THE DRILL SERGEANT: St George Mining (ASX: SGQ) has claimed confirmation of nickel‐copper sulphide mineralisation at a further two EM conductors recently drill tested at the company’s Mt Alexander project.
St George completed drill holes MAD17 and MAD19 to test two separate downhole EM conductors located in the northern section of the Cathedrals orospect below the Cathedrals ultramafic.
MAD17 was completed to a downhole depth of 200m and was designed to intersect an EM plate at 167m downhole.
MAD19 is situated 50m to the north‐east of MAD17, and was also completed to a downhole depth of 200m to test another EM plate at 153m downhole.
Both MAD17 and MAD19 intersected nickel‐copper sulphide mineralisation.
According to St George MAD17 intersected approximately 6.5 metres of ultramafic‐hosted sulphide mineralisation from 164.5m to 170.9m which comprises:
4.5m, from 164.5 to 168.9m, of moderate increasing to strong disseminated sulphides (averages 0.65 per cent nickel, 0.4 per cent copper) with some interstitial stringer sulphides (average 2.1 per cent nickel, 1 per cent copper); and
2m, from 168.9 to 170.9m, of stringer‐matrix and massive sulphides up to 15cm thick (very variable spot XRF readings that average over the 2m interval at 4.3 per cent nickel and 3.2 per cent copper)
St George indicated the metal values it quoted in its ASX announcement are based on field XRF analysis, stressing they are preliminary only.
The company said a conclusive determination of the nickel and copper content of the sulphide mineralisation will be confirmed when laboratory assays are available.
St George did say, however, that based on the intersection angle of the drilling and interpreted EM plate, the down‐hole widths are interpreted to approximate true widths.
MAD19 intersected approximately 3.12m of ultramafic‐hosted disseminated and stringer‐matrix sulphide mineralisation from 156.71m to 159.83m including intervals of massive sulphides from 156.94 to 157.11m and from 158.77 to 159.13m.
St George explained the sulphide textures and mineralogy observed are similar to the intersection in MAD17, with the overall interval comprising approximately 40 per cent sulphides.
XRF analysis has not yet been completed for MAD19.
St George has now commenced drilling of MAD20 at the Stricklands prospect, located within the Cathedrals shear zone and approximately one kilometre west‐southwest of the Cathedrals prospect.
This is the first ever drilling at Stricklands, where six EM conductors are planned for testing in this program.
“Our drill program is continuing to deliver outstanding results with another two EM conductors confirmed as nickel‐copper sulphide mineralisation,” St George Mining executive chairman John Prineas said in the company’s announcement to the Australian Securities Exchange.
“Drilling has now commenced at the Stricklands prospect where six previously untested EM conductors in prospective geological positions will be drilled.
“We have an excellent opportunity to make a discovery at Stricklands and the drilling results from these targets will be highly anticipated.”
