Growth focused Western Australian nickel company St George Mining (ASX: SGQ) today announced that multiple new EM conductors have been identified through ongoing exploration at its flagship Mt Alexander Project, located in the north-eastern Goldfields.
HIGHLIGHTS:
-
New off-hole electromagnetic (EM) conductors have been identified by the downhole EM (DHEM) surveys in MAD185, MAD192 and MAD193 – all of which intersected mineralised ultramafic.
-
Five EM conductors were identified from MAD185 with the two highest priority targets modelled with conductivity of 33,100 Siemens and 14,225 Siemens, respectively.
-
Two EM conductors were identified from MAD192 with modelled conductivity of 55,550 Siemens and 26,000 Siemens, respectively.
-
Four EM conductors were identified from MAD193 with the two highest priority targets modelled with conductivity of 4,585 Siemens and 2,850 Siemens, respectively.
-
All new EM conductors are situated within the large interpreted mafic-ultramafic unit that is known to host massive nickel-copper sulphides in other parts of the Cathedrals Belt at the Mt Alexander Project.
-
The new conductors are located approximately 500m to 800m north-west of known massive sulphides in the Cathedrals Belt and represent excellent targets for the potential discovery of new nickel-copper sulphide deposits.
More strong EM targets for massive nickel-copper sulphides
DHEM surveys on three recently completed deeper drill holes have identified a number of new EM conductors.
Drill holes MAD185, MAD192 and MAD193 each returned thick intersections of the mafic-ultramafic unit that spans more than 5km across the east-west oriented Cathedrals Belt. Importantly, each hole also intersected an interval of disseminated nickel-copper sulphides on the basal contact of the mafic-ultramafic unit.
This geology is highly encouraging for the potential presence of massive nickel-copper sulphides nearby.
The identification of off-hole EM conductors in each of these holes is an exciting exploration result that further supports the potential to discover nickel-copper sulphide mineralisation proximal to these holes.
John Prineas, St George Mining’s Executive Chairman, said:
“The concurrent use of drilling and downhole EM surveys is continuing to deliver breakthrough results with outstanding nickel-copper sulphide targets identified in an area that has never been drilled.
“These are the deepest EM conductors identified in the Cathedrals Belt and support the continuity of highgrade mineralisation at depth and in the north-west down-dip direction of what we already know is a large intrusive mineral system.
“The identification of nickel-copper sulphides in the conductors modelled from MAD192 and MAD193 will establish the West End Prospect – which covers a 2.5km strike of the Cathedrals Belt and straddles the major Ida Fault – as a fertile and highly prospective area for further mineralisation.
“We are confident that the strongest of these new conductors will be confirmed by drilling to represent massive sulphide mineralisation.”
