More thick intersections significantly extend high-grade nickel copper sulphide mineralisation at Mt Alexander: St George

  • 21 October

Growth-focused Western Australian nickel company St George Mining (ASX: SGQ) has announced that drilling has established further significant extensions of high grade mineralisation at its flagship Mt Alexander Project, located in the north-eastern Goldfields.


HIGHLIGHTS

·       Large step-out hole at Investigators Prospect intersects thick nickel-copper sulphides 100m along strike of known mineralisation:

·       18m thick ultramafic intersected at Investigators East – including 7m of nickel-copper sulphide – from 91.9m downhole in drill hole MAD166

·       The intersection in MAD166 is 100m along strike of previously known mineralisation, significantly increasing the strike of high-grade mineralisation at Investigators East

·       Mineralisation remains open in the north-northwest down-dip direction

·       Laboratory assays confirm a significant down-plunge extension of high-grade mineralisation at the Stricklands Prospect:

·       MARC128 has returned assays of

·       5m @ 2.97% Ni, 1.04% Cu, 1.02 g/t PGEs from 83m, including

·       3m @ 4.34% Ni, 1.11% Cu, 1.05gpt PGEs from 84m

·       MARC128 is 100m down-plunge of the exceptional intersection in MAD71 (17.45m @ 3.01% Ni, 1.31% Cu, 0.13% Co and 1.68g/t total PGEs from 37.45m) and 50m downplunge from previously known high-grade mineralisation

·       MARC128 significantly increases the down-plunge strike of mineralisation at Stricklands with mineralisation open in the north-northwest down-dip direction

·       Geological interpretation indicates potential for down-plunge extensions at Stricklands and Investigators to connect at depth as part of a larger intrusive mineral system

John Prineas, St George Mining’s Executive Chairman, 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 the known shallow nickel-sulphide deposits.

“The down-plunge extensions are all pointing in the same north-northwest direction, giving weight to the geological model that there may be a larger, intrusive-style nickel sulphide deposit at depth.

“Field activities continue in full swing with diamond drilling 24/7, downhole EM surveys underway and further surface EM surveys about to resume. A second drill rig is also scheduled to arrive soon.

“We will continue to test the down-plunge extensions at Investigators and Stricklands and are also excited to be escalating drilling at the new targets at Radar, Bullets and Fish Hook.”
