Growth‐focused Western Australian nickel company St George Mining Limited (ASX: SGQ) has announced that DHEM surveys carried out in drill holes completed earlier this year and in late 2018 have generated a large number of priority EM targets for the nickel-copper sulphide drill program to commence soon at the Company’s flagship Mt Alexander Project, located in the north-eastern Goldfields.
Growth‐focused Western Australian nickel company St George Mining Limited (ASX: SGQ) has announced that DHEM surveys carried out in drill holes completed earlier this year and in late 2018 have generated a large number of priority EM targets for the nickel-copper sulphide drill programme to commence soon at the Company’s flagship Mt Alexander Project, located in the north-eastern Goldfields.
HIGHLIGHTS
· 42 new electromagnetic (EM) conductors have been prioritised and scheduled for immediate drilling
· The prioritised EM conductors have been identified by downhole EM (DHEM) surveys, which detected 73 off-hole anomalies in total
· All EM conductors tested in the Cathedrals Belt to date have been confirmed as nickelcopper sulphides, giving a high level of confidence in the new EM drill targets
· Quantity and location of the EM conductors indicates outstanding potential to significantly increase the volume of high-grade mineralisation at Mt Alexander
· Drilling is scheduled to commence on or about 22 July 2019
DHEM surveys identified 73 off-hole EM anomalies in total, indicating very strong potential for the presence of much more high-grade mineralisation than has been recognised by the drilling to date. 42 of these EM conductors have been prioritised for drilling in the upcoming drill programme.
Importantly, a number of the new EM conductors are located away from known zones of nickel-copper sulphides and offer an excellent opportunity to significantly extend the ore-bodies in the Cathedrals Belt.
Some of the new conductors are proximal to existing nickel-copper sulphides and are classified as infill targets that are likely to confirm an increase in the continuity of known mineralisation.
There are also some deeper EM conductors located down-plunge of known high-grade nickel-copper sulphides, towards the north-northwest. As the known mineralised ultramafic units are interpreted to extend in this direction, these targets may represent a continuation of high-grade mineralisation at depth.
John Prineas, St George Mining’s Executive said: “Drilling will start shortly at Mt Alexander with a targeted programme to scope out the scale of the discoveries in the Cathedrals Belt and to accelerate resource definition.
“The sheer number of EM conductors to be drilled in the Cathedrals Belt reflects the large scale of the mineral system at Mt Alexander, and its potential to host substantial strike lengths of mineralisation.
“In addition to the new EM conductors, we will drill some deep holes at Fairbridge to test for the source of the many nickel-copper gossans at surface.
“All EM conductors drilled in the Cathedrals Belt to date have been confirmed as nickel-copper sulphides, so we have confidence that the upcoming drilling will discover more high-grade mineralisation.”
