St George kicks off Moving Loop EM survey

/in /by

THE DRILL SERGEANT: St George Mining (ASX: SGQ ) has commenced a moving loop electro‐magnetic (MLEM) survey over high-priority nickel targets situated along the Stella Range Ultramafic Belt at the company’s East Laverton property in the North Eastern Goldfields region of Western Australia.

The MLEM survey will be carried out over the Cambridge prospect and has been designed to assess prospective zones of the Cambridge dunite body that were not included in the scope of a initial FLEM (fixed loop electro ‐ magnetic) survey the company commenced earlier this week.

announcementSt George considers these areas to be prospective for massive sulphide mineralisation.

The company has identified the north‐east corner of the dunite body as one area of particular interest where an EM anomaly was detected on the basal contact by a historical MLEM survey.

This area was previously part of the Project Dragon farm ‐ in arrangement with BHP Billiton (ASX: BHP) and the EM conductor has yet to be tested.

The MLEM survey will also investigate a priority area of the Stella Range Ultramafic Belt that was shown to host primary nickel sulphides by drilling completed in 2012.

Disseminated nickel sulphides intersections included:

18 metres ta 0.4 per cent nickel, including 4 metres at 0.57 per cent nickel and 2 metres at 0.51 per cent nickel; and

6m at 0.48 per cent nickel, including 2m at 0.62 per cent nickel.

Further mineralisation of 2m at 1.08 per cent nickel was also encountered, which St George interpreted to be a ‘tectonic‐slice’ of mineralised ultramafic, preserved by intense silicification.

“It is likely that this raft of ultramafic has a local source, implying that a larger mineralised ultramafic unit may be proximally situated to [previous drilling results] DDNRC002,” St George said in its ASX announcement.

“The three occurrences of nickel sulphide mineralisation over a 12 kilometre strike of high manganese oxide ultramafic strongly support the potential for multiple mineralised systems to be present within this zone.

“The MLEM survey will be completed over this 12 kilometre priority zone to identify conductive anomalies that may represent massive sulphides.”
