ASX-listed explorer, St George Mining, has observed further massive sulphide mineralisation in diamond drill core at its Investigators East prospect, located within the company’s flagship Mt Alexander Project near Leonora in WA.
The company said the core was taken from a hole that was designed to intersect a prospective geological sequence about 100m along strike from previously identified mineralisation at Investigators East.
The company said it had punched through an 18m-wide ultramafic unit that contained 7m of visible nickel-copper sulphides from 91.9m down-hole.
Nearly a metre of massive sulphides yielded preliminary portable XRF readings of 6.5% nickel and 2.3% copper.
Whilst these numbers are still subject to verification from laboratory assays, they are still cause for quiet excitement.
Nearby, at the Stricklands prospect, laboratory assays have confirmed mineralisation at depth with 5m @ 2.7% nickel, 1.04% copper and 1.02g/t PGMs from 83m down-hole. This included a higher grade intercept of 3m @ 4.34% nickel, 1.11% copper and 1.05 PGMs from 84m.
St George Mining Executive Chairman John Prineas, said: “Step-out drilling continues to deliver excellent results across our Mt Alexander project with more hits of high-grade mineralisation both down-plunge and along strike of known shallow nickel-sulphide deposits.”
“Field activities continue in full swing with diamond drilling 24/7, down-hole EM (electromagnetic) surveys underway and further surface EM surveys about to resume. A second drill rig is also scheduled to arrive soon.”
Mineralisation at Stricklands remains open to the north-west and at depth.
St George has also completed two down-hole electromagnetic surveys at its newly discovered Radar prospect. Data analysis points to a strong off-hole conductor to the west of the discovery hole, which returned shallow assays of 6m @ 2.14% nickel, 0.74% copper and 1.62g/t PGMs from only 46m down-hole.
Follow-up drilling at Radar will be finalised once the 3D data modelling of the electromagnetic anomalies is completed.
