ST GEORGE IDENTIFIES OUTSTANDING MASSIVE NICKEL SULPHIDE TARGETS AT DESERT DRAGON CENTRAL

HIGHLIGHTS:

  • Two very strong, late‐time EM conductors identified at Desert Dragon Central for drilling

  • The EM conductors are modelled on the margins of the ultramafic and within a prominent fold on the Stella Range belt, a highly favourable setting for the concentration of massive nickel sulphides

  • Target 4 EM conductor is co‐incident with a strong gravity anomaly which typically reflects sulphide‐rich rocks

  • Target 5 EM conductor has exceptionally high time constant of 443 milliseconds and high conductance of 4900 Siemens indicating a thick conductive body

  • Drilling to commence in early April 2015

EM CONDUCTORS WITH FAVOURABLE GEOLOGICAL AND STRUCTURAL FEATURES SIGNIFICANTLY SUPPORTING THEIR POTENTIAL TO REPRESENT MASSIVE NICKEL SULPHIDES

St George Mining Ltd (“St George” or “the Company”) is pleased to announce the identification of additional high quality nickel sulphide targets at its 100% owned East Laverton Nickel Sulphide Project in Western Australia (“St George’s Project” or “the Project”).

The moving loop electromagnetic (MLEM) survey recently completed by Newexco at the Desert Dragon prospect has identified several EM anomalies, two of which have been recommended by global nickel expert Dr Jon Hronsky for immediate drilling.

The two targets – named Target 4 and Target 5 – are each powerful EM conductors with time decay and conductance that are consistent with massive sulphides. At Target 4, the EM conductor has a time constant of 190ms and a conductance of 3500 Siemens.

At Target 5, the EM conductor has an exceptional time constant of 443ms and a very strong conductance of 4900 Siemens. This EM response is indicative of a very thick conductive body.

Importantly, each of these EM conductors is modelled on the ultramafic contact of the high‐MgO channel that hosts the nickel sulphide mineralisation intersected at drill hole DRAC35 (see Figure 1). The presence of known nickel sulphides in this channel significantly increases the potential of the ultramafic contact to host massive nickel sulphide mineralisation.

Also of importance is the location of the targets within the most prominent fold feature of the Stella Range belt. Fold closures or ‘noses’ are favourable sites for the accumulation of massive sulphides and are a priority search area in nickel sulphide exploration.

Mr John Prineas, Executive Chairman of St George Mining said:

“These EM conductors are outstanding targets for massive nickel sulphide mineralisation.

“Target 5, in particular, is a very strong EM conductor with remarkable conductivity and time decay that are an excellent fit for a nickel sulphide deposit.

Figure 1 – a map of Desert Dragon Central showing the interpreted geology and the prominent fold in the Stella Range belt. The two immediate targets are strong EM conductors located on the ultramafic contact of a high‐MgO ultramafic complex ‐ a high priority target zone for massive nickel sulphides. The location of the targets in the limb of a very prominent fold ‘nose’ in the Stella Range belt is also favourable for the structural concentration of massive nickel sulphides.

TARGET 4 – IS DRAC35 ON THE MARGIN OF A MAJOR NICKEL SULPHIDE SYSTEM ?

Drilling at Target 4 will focus on the easterly margin of a strong late‐time EM conductor which is in contact with the western margin of a positive gravity feature. The gravity anomaly is interpreted to reflect dense sulphide‐rich rocks, which may include nickel sulphides.

Significantly, there is a strong correlation between where the EM response peaks, and where the conductor intersects the margin of the gravity anomaly (see Figure 3). This area is favourably situated near the ultramafic contact, a site where massive nickel sulphides typically accumulate.

The conductor was identified by Newexco and labelled ‘Anomaly 9’. It has been modelled as a single plate that has a shallow westerly dipping orientation away from the intersection with the gravity anomaly. It is a short‐strike conductor modelled as 500m x 700m, with a high conductance and time decay that is consistent with massive sulphides.

Drill hole DRAC35 was completed at Desert Dragon Central by BHP Billiton Nickel West in 2012 and intersected 18m @ 0.40%Ni from 100m (including 4m @ 0.57%Ni from 100m). A downhole analysis of DRAC35 is illustrated in Figure 2.

==> picture [489 x 301] intentionally omitted <==

Figure 2 – Downhole profile of drill hole DRAC35. The hole intersected 18m @ 0.40%Ni in orthocumulate ultramafics in contact with a sheared margin of an ultramafic channel complex. Geochemical interpretation suggests these are remobilised sulphides from a proximal source.

ASX / MEDIA RELEASE

==> picture [120 x 55] intentionally omitted <==

The thick interval of disseminated nickel sulphides in DRAC35 is interpreted to be within the sheared margin of a major komatiite channel flow to the south of the drill hole. The nickel sulphides in DRAC35 are interpreted as being remobilised from a nearby body of nickel sulphides, during an alteration event.

Target 4 is located to the southwest of drill hole DRAC35 and is interpreted as the closest potential source for the remobilised sulphides encountered in DRAC35.

Lithogeochemical analysis of DRAC35 and other drilling at Desert Dragon indicates a southerly vector from DRAC35 towards where a local komatiite hosted nickel sulphide system may be situated. A ground gravity survey was completed over this area to the south of DRAC35 and confirmed the presence of a large komatiite channel complex.

Target 4 has favourable geological, geochemical and structural features which corroborate the potential for the intersection of the EM conductor and the margin of the gravity anomaly to represent a massive nickel sulphide body. This is a priority drill target to test for massive nickel sulphide mineralisation.

TARGET 5 – VERY STRONG EM CONDUCTOR IN FOLD OF THE ULTRAMAFIC BELT

Target 5 is comprised of a very powerful EM conductor identified by Newexco and labelled ‘Anomaly 10’.

It is situated near the ultramafic contact of the same large high‐MgO komatiite channel complex as Target 4. This is a classic setting for massive nickel sulphide mineralisation.

The EM conductor has a relatively short strike length of approximately 500m and is modelled as a 500m x 550m plate having a shallow (35 degree) westerly dip.

The conductive plate for Anomaly 10 has a very powerful response at 4900 Siemens. The decay has an extremely impressive time constant of 443ms calculated over a number of late time channels which show a clear exponential decay profile.

The combination of very high conductivity and exceptional time decay suggests a very thick conductive body that could potentially represent a massive nickel sulphide deposit.

Also of significance is that the conductance and time constant for Anomaly 10 are markedly higher than the other surrounding EM plates, which suggests that this conductor may be related to an isolated and unique source.

The very strong EM conductor at Target 5 is situated in an ideal setting within the fold of the Stella Range belt and near the contact of a high‐MgO komatiite channel at which disseminated nickel sulphides have already been discovered.

This makes Target 5 a compelling drill target for massive nickel sulphides.

completed recently at the Project.
These examples should not be taken as limiting
the broad meaning of sampling.

Drilling programs have included diamond core drilling completed by
DDH1 Drilling Pty Ltd and reverse circulation (RC) drilling completed
by VM Drilling Pty Ltd.
Diamond drilling was undertaken by DDH1 in 2014 using a Sandvik
1200 Multipurpose truck mounted drill rig. RC drilling was
undertaken by VM Drilling in 2014 using a Schramm 685 truck
mounted drill rig.
_Diamond Core Sampling:_The core is removed from the drill rig and
laid out for initial analysis in the field. The core is measured and
marked up at 1m intervals against the drillers blocks, which are
themselves checked against the drillers log books where required.
The visible structural features on the core are measured against the
core-orientation lines.
Onsite XRF analysis is conducted using a hand-held Olympus Innov-X
Spectrum Analyser. The XRF analysis is used to systematically review
diamond drill core, with a single reading taken every metre, except
in the case of core loss. These results are only used for onsite
interpretation and preliminary base metal assessment subject to
final geochemical analysis by laboratory assays.
The sections of the core that are selected for assaying are marked
up and recorded on a “cut-sheet” which provides a control on the
intervals that will be cut and sampled at a duly certified assay
laboratory, SGS Laboratories. Core is prepared for analysis at 1m
intervals or at lesser intervals of geological significance. Core is cut
in half lengthways and then numbered samples are taken as per the
“cut-sheet”.
Diamond core provides high quality samples that are logged for
lithological, structural, geotechnical, density and other attributes.
Sampling is carried out under QAQC procedures as per industry best
practice.
RC Sampling: All samples from the RC drilling are taken as 1m
samples. Samples are sent to Intertek Laboratories for assaying.
Appropriate QAQC samples (standards, blanks and duplicates) are
inserted into the sequences as per industry best practice.
Samples are collected using cone or riffle splitter. Geological logging
of RC chips is completed at site with representative chips being
stored in drill chip trays.
Onsite XRF analysis is conducted on the fines from RC chips using a
hand-held Olympus Innov-X Spectrum Analyser. These results are
only used for onsite interpretation and preliminary assessment
subject to final geochemical analysis by laboratory assays.

were conducted using a single shot camera every 30m to detect
deviations of the hole from the planned dip and azimuth. The drill-
hole collar locations were recorded using a hand held GPS, which
has an accuracy of +/- 5m. At a later date the drill-hole collar will be
surveyed to a greater degree of accuracy.
_RC Sampling:_The RC drilling rig has a cone splitter built into the
cyclone on the rig. Samples are taken on a one meter basis and
collected directly from the splitter into uniquely numbered calico
bags. The calico bag contains a representative sample from the drill
return for that metre. This results in a representative sample being
taken from drill return, for that metre of drilling. The remaining
majority of the sample return for that metre is collected and stored
in a green plastic bag marked with that specific metre interval. The
cyclone is blown through with compressed air after each plastic and
calico sample bag is removed. If wet sample or clays are
encountered then the cyclone is opened and cleaned manually and
with the aid of a compressed air gun.
A large auxiliary compressor (“air-pack”) is mounted on a separate
truck and the airstream is connected to the rig. This provides an
addition to the compressed air supplied bythe in-built compressors

Criteria JORC Code explanation Commentary
mounted on the drill rig itself. This auxiliary compressor maximises
the sample return through restricting air pressure loss, especially in
deeper holes. In addition, the high and consistent levels of air
pressure minimise the number of drill samples.
Geological logging of RC chips is completed at site with
representative chips being stored in drill chip trays. Downhole
surveys of dip and azimuth are conducted using a single shot camera
every 30m to detect deviations of the hole from the planned dip and
azimuth. The drill-hole collar locations were recorded using a hand
held GPS, which has an accuracy of +/- 5m. At a later date the drill-
hole collar will be surveyed to a greater degree of accuracy.
_MLEM Survey:_Field calibration of the survey instruments using
standards is undertaken each day. A minimum of 3 consistent
readings per station are taken to ensure accuracy of data collected.
_DHEM Survey:_For the DHEM survey, the polarity of each component
is checked to ensure the system was set up using the correct
component orientations. The hole position is corrected for
trajectory using orientation survey data.

Parties East Laverton Property as part of the Project Dragon farm-in
arrangement between Nickel West and the Company. That farm-in
arrangement has been terminated. The drilling programme
comprised 35 RC holes for 8,560m drilled.
The results from the Nickel West drilling programme were reported
by the Company in its ASX Release dated 25 October 2012 “Drill
Results at Project Dragon”. Drilling intersected primary nickel
sulphide mineralisation and established the presence of fertile, high
MgO ultramafic sequences at the East Laverton Property.
Prior to the Project Dragon drilling programme, there was no
systematic exploration for nickel sulphides at the East Laverton
Property. Historical exploration in the region was dominated by
shallow RAB and aircore drilling, much of which had been
incompletely sampled, assayed, and logged. This early work was
focused on gold rather than nickel sulphide exploration.
Geology Deposit type, geological setting and style of The Company’s East Laverton Property located in the NE corner of
mineralisation the Eastern Goldfields Province of the Archean Yilgarn Craton. The
project area is proximally located to the Burtville-Yarmana terrane
boundary and the paleo-cratonic marginal setting is consistent with
the extensive komatiites found on the property.
The drilling at the East Laverton Property has confirmed extensive
strike lengths of high-MgO olivine-rich rocks across three major
ultramafic belts. Ultramafic rocks of this composition are known to
host high grade nickel sulphides.
