Growth-focused Western Australian nickel company St George Mining (ASX: SGQ) has announced that drilling of deeper EM conductors has delivered more thick intercepts of high-grade mineralisation at the Mt Alexander Project, located in the north-eastern Goldfields.
HIGHLIGHTS
· Thick intersections of nickel-copper sulphides, including massive sulphide mineralisation, in two further drill holes – MAD173 and MAD174 – completed to test deeper electromagnetic (EM) conductors
· MAD173 and MAD174 are large step-out holes located down-dip at the Investigators Prospect and, together with MAD172, confirm an east-west strike of nickel-copper sulphide mineralisation at depth for more than 800m
· Down-plunge extent of high-grade mineralisation is increased to more than 300m with mineralisation open to the north-west and in the down-dip direction
· Style of mineralisation intersected is consistent with mineralisation that has been structurally remobilised from a larger and proximal source of high-grade nickel-copper sulphides
· Diamond drilling continues 24/7
Drill holes MAD173 and MAD174 have intersected nickel-copper sulphide mineralisation along the downdip extension of the Investigators ultramafic unit at depths not previously explored.
The holes were completed to test EM conductors identified by the downhole EM (DHEM) surveys in the recently completed deeper stratigraphic holes along the Cathedrals Belt. Together with MAD172 – reported in our ASX Release dated 12 November 2019 ‘Thick Intercept in Deeper Drilling of Conductors’ – the drill holes establish a deeper east-west strike of high-grade mineralisation of more than 800m.
The shallow nickel-copper sulphide deposits at Investigators commence 30m from surface. The latest intersections increase the down-plunge extent of high-grade mineralisation to more than 300m.
John Prineas, St George Mining’s Executive Chairman, said: “These drill results are further evidence of the large high-grade mineral system at the Cathedrals Belt, with significant down-plunge extensions established and mineralisation open in the down-dip direction.
“With only limited drilling at depth, we believe there is strong potential to significantly increase the scale of defined mineralisation, both along strike and at depth.”
