Small cap nickel explorer St George Mining has identified four, strong, off-hole electromagnetic conductors that require immediate drill testing at its Investigators prospect, 100km west of Leonora in the northern Goldfields region of W.A.
The conductors were discovered from down-hole electromagnetic surveying within existing drill holes and represent prospective looking new drill targets for defining further massive nickel-sulphide mineralisation at the project.
The principal EM target is interpreted to be 120m down-plunge of a significant intersection of 5.3 metres grading 4.95% nickel, 2.75% copper, 0.16% cobalt and 4.55 grams per tonne total PGE’s from 157.9m down-hole, drilled last year.
The Investigators prospect is the largest system identified at St George’s emerging Mt Alexander project to date and covers an east-west strike extent of over 1.3km.
The company reports that the intersections of high-grade nickel-copper sulphide mineralisation discovered at Investigators, do not yet fully account for the expansive EM signature recorded there.
The new conductors are considered excellent targets for delineating new thicknesses of potentially economic mineralisation at relatively shallow depths.
The company is also testing for the potential thickening, repetition and/or extensions of the mineralised ultramafic rock sequence with the new drilling.
St George’s Executive Chairman John Prineas said: “We are excited to have four high quality EM targets ready to be drilled at Investigators.”
“These strong DHEM conductors are along strike or down dip from known zones of high-grade mineralisation and present as excellent targets to extend the area of nickel-copper sulphide mineralisation at Investigators.”
According to the company, diamond drilling of the 4 new geophysical EM targets is expected to commence in about 2 weeks, pending suitable rig availability.
