ST GEORGE IDENTIFIES EXCEPTIONAL MASSIVE NICKEL‐COPPER SULPHIDE TARGETS AT MT ALEXANDER PROJECT
HIGHLIGHTS:
-
Review by St George of newly acquired project data confirms significant exploration upside at Mt Alexander Project
-
Several untested and drill‐ready electromagnetic (EM) conductors identified at both the Cathedrals and Stricklands Prospects are exceptional targets for further massive nickel‐copper sulphide mineralisation
-
The fertile ultramafic at Cathedrals and Stricklands is interpreted to extend for a total strike length of 1.5km with potential for multiple nickel sulphide deposits
-
Strong exploration potential emerging across the broader project area
-
2016 drill programme being finalised
DATA REVIEW HIGHLIGHTS EXCEPTIONAL EXPLORATION TARGETS
St George Mining Limited (ASX: SGQ ) (‘St George’ or ‘the Company’) is pleased to announce that its ongoing review of project data acquired from BHP Billiton for the Mt Alexander Project has confirmed drill‐ready targets with outstanding potential for further discoveries of massive nickel‐copper sulphide mineralisation.
St George’s technical team, in conjunction with geophysical consultants Newexco, commenced a comprehensive review of the substantial project data following completion of the acquisition of a 75% interest in the core Mt Alexander tenement from BHP Billiton.
High grade nickel‐copper sulphides were discovered at the Cathedrals Prospect in 2008. Three EM conductors have been drilled at Cathedrals to date with all three resulting in intersections of massive nickel‐copper sulphides. Our data review has identified five untested downhole EM (DHEM) plates at Cathedrals, which offer an opportunity to define further mineralisation at this Prospect.
The Stricklands Prospect, located to the west of Cathedrals and never drilled, has several untested EM conductors that have similar geophysical responses to the massive nickel‐copper sulphides at Cathedrals. The Stricklands EM conductors, like those at Cathedrals, are associated with magnetic anomalies within the Cathedrals shear zone. These conductors have strong potential for a new discovery and are priority drill targets for the 2016 drill programme at Mt Alexander.
St George Mining Executive Chairman, John Prineas said:
“Our review of the project data has re‐enforced our assessment that Mt Alexander has significant exploration upside. In addition to the walk‐up drill targets at Cathedrals and Stricklands, there is also a tremendous pipeline of targets emerging across the broader project area.
“We are increasingly confident that our upcoming drill programme will result in further discoveries of massive nickel‐copper sulphides.“

STRICKLANDS AND CATHEDRALS PROSPECTS – DRILL‐READY TARGETS
A fixed loop electromagnetic (FLEM) survey was completed by BHP Billiton at Stricklands utilising a high temperature SQUID (superconducting quantum interference device) sensor, which provides very high resolution data and minimises noise levels from conductive cover.
Our technical team, in conjunction with Newexco, has reviewed the FLEM survey data and confirmed seven EM conductors at Stricklands that warrant immediate further exploration. These EM conductors have similar geophysical responses to the massive nickel‐copper sulphide EM conductors drilled in 2008 at the nearby Cathedrals Prospect. None of the seven EM conductors at Stricklands have been drill tested.
Five of these seven untested EM conductors are also associated with strong magnetic anomalies within the prospective Cathedrals shear zone. The 100% success rate of previous drilling of EM conductors in the Cathedrals shear zone provides strong encouragement for the drill testing of the Stricklands EM conductors.
At the Cathedrals Prospect, twenty five holes were drilled by BHP Billiton to test the komatiite ultramafics. Six of the drill holes intersected nickel sulphides including three holes that intersected high grade nickel‐ copper‐PGE mineralisation. These three drill holes tested EM conductors identified by FLEM and DHEM surveys carried out by BHP Billiton. DHEM surveys completed in the Cathedrals drill holes have also identified a further five EM conductors that remain untested and have potential to represent further nickel‐ copper sulphide mineralisation.
Figure 1 shows the location of the untested EM conductors at Stricklands and Cathedrals. The fertile ultramafic that hosts these EM conductors is defined by strong magnetic anomalies, and extends for a combined strike length of 1.5km. The drilling of the EM conductors within this area has the potential to discover further massive nickel‐copper sulphide mineralisation.

Table 1 contains details of these EM conductors. All the EM plates are highly conductive, ranging from 6,000 up to 16,000 Siemens, which is consistent with the EM response of previously drilled massive nickel sulphides at Cathedrals.
These EM conductors will be prioritised for testing in our upcoming drill programme at Mt Alexander.
EMERGING EXPLORATION POTENTIAL AT MT ALEXANDER
The Cathedrals nickel‐copper‐PGE discovery was made at the Mt Alexander Project in 2008 with significant intersections including:
-
4m @ 4.9%Ni, 1.7%Cu and 3.9g/t total PGEs from 91.4m in drill hole MAD12
-
3m @ 3.8%Ni, 1.6%Cu and 2.7g/t total PGEs from 56.3m in drill hole MAD13
-
6m @ 3.3%Ni, 1.5%Cu and 2.7g/t total PGEs from 60m in drill hole MARC49
These high grade intersections are within komatiite ultramafics that are hosted in the Cathedrals shear zone. This shear zone remains largely untested along strike from the Cathedrals Ni‐Cu‐PGE discovery. In particular, the area to the west of the Stricklands Prospect within the Cathedrals shear zone has no EM coverage or drill testing; see Figure 2.
This untested area hosts several prominent magnetic anomalies which may represent further prospective ultramafic rocks, and are priority exploration targets. Newexco is designing a surface EM survey for this area to identify any bedrock conductors for drill testing.
Our comprehensive review of the camp‐scale potential at Mt Alexander is continuing and we anticipate further exploration targets to emerge from this review.
One area of particular interest is the Mt Alexander greenstone belt where previous drilling has identified sporadic komatiite hosted nickel sulphide mineralisation, including some intersections of massive nickel sulphides, over a seven kilometre strike within the Western Ultramafic unit.
The previous drilling was often completed as wide‐spaced drill holes or single drill holes, rather than a fence of holes, and as such a significant portion of the ultramafic sequences have not been tested.
This belt remains under‐explored and is being closely assessed by our technical team in conjunction with nickel sulphide expert Dr Martin Gole. The presence of extensive fertile komatiite ultramafics with some massive nickel sulphides warrants further exploration.
In addition to reviewing the camp‐scale potential at Mt Alexander, a detailed review has commenced on the geology and mineralisation at the Cathedrals nickel‐copper‐PGE discovery. This review will assess the controls on the high‐grade mineralisation and evaluate the potential for any extensions to known mineralisation (laterally and at depth).
We expect to take delivery of the historical drill core and RC chips from previous drilling next week. Detailed analysis of the drill samples will enable a more comprehensive review of this important greenfields discovery.
Further details of our project review and the upcoming drill programme at Mt Alexander will be announced shortly.

ABOUT THE MT ALEXANDER PROJECT:
The Mt Alexander Project is located 120km south‐southwest of the Agnew‐Wiluna belt which hosts numerous world class nickel deposits. The Project comprises two granted exploration licences – E29/638 and E29/548.
The Cathedrals Ni‐Cu discovery and the Stricklands Prospect are located on E29/638, which is held in joint venture by Western Areas Limited (25%) and St George (75%). St George is the Manager of the Project with Western Areas retaining a 25% non‐contributing interest in the Project (in regard to E29/638 only) until there is a decision to mine.
