Emerging WA nickel stock St George Mining (ASX: SGQ) says the first hole of a new drilling campaign at the Mt Alexander project near Leonora has intersected high-grade nickel-copper sulphide mineralisation. XRF readings of the core about 200m downhole returned grades of 8% nickel and 7% copper. Assay results are pending. The hole was drilled at the Investigators prospect and confirms the high-grade prospectivity. Drilling continues at Investigators.
- MAD108 is the first drill hole completed in the current programme at Mt Alexander and has successfully intersected electromagnetic (EM) conductor MAD98:X1 at Investigators
- High-grade nickel-copper sulphides confirmed at MAD98:X1 (based on portable XRF analysis with laboratory assays pending)
- Drilling is continuing with the second drill hole at Investigators underway
Emerging Western Australian nickel company St George Mining Limited (ASX: SGQ) (“St George” or “the Company”) is pleased to announce that high grade nickel-copper sulphides have been intersected in the first drill hole completed in the drill programme underway at the Mt Alexander Project, located near Leonora in the north-eastern Goldfields.
MAD108 was completed at the Investigators Prospect to test EM conductor MAD98:X1 which was modelled at 205m downhole.
The drill hole successfully intersected:
- 7.55m of sulphide mineralisation between 199.75m to 207.3m downhole, including
- massive sulphides between 206.03m to 207.3m downhole with average XRF readings of 8%Ni and 7%Cu.
MAD108 confirms intersections of mineralisation on the MAD60 section at Investigators over a very significant 320m plunge length with mineralisation open to the north-west (see Figure 1).
The photograph on the right shows drill core of MAD108 from the massive sulphides intersected between 206.03m to 207.3m downhole. Coarse grained pentlandite and chalcopyrite are evident in the drill core.
Laboratory assays are pending and are required to confirm the grades shown herein which are based on portable XRF analysis only. Further details of the mineralised interval are set out below:
Significantly, the intersection of massive sulphides in MAD108 confirms down dip continuity over 100m from the thick, high grade nickel-copper sulphide mineralisation in MAD60 of 5.3m @ 4.95%Ni, 2.75%Cu, 0.16%Co, and 4.55g/t total PGEs from 157.9m.
The down dip plunge of nickel-copper sulphide mineralisation on the MAD60 section has been increased to 320m (see Figure 1) and mineralisation remains open to the north-west.
