GLOBAL NICKEL EXPERT ENDORSES EAST LAVERTON PROJECT’S CREDENTIALS AS NEW NICKEL SULPHIDE CAMP

HIGHLIGHTS:

  • Review by global nickel expert backs potential for new nickel camp

  • Exploration opportunity de‐risked by substantial field work to date

  • Presence of key criteria for major nickel sulphide deposits confirmed

  • Favourable geological similarities to Forrestania and Agnew‐Wiluna nickel camps

  • Immediate follow‐up exploration at Desert Dragon and Windsor prospects recommended

  • Planning of new drill targets in progress

  • Drilling to re‐commence in March 2015

TECHNICAL REVIEW – EXECUTIVE SUMMARY

St George Mining Limited (ASX: SGQ) (“St George” or “the Company”) is pleased to announce that the Technical Review of its 100% owned East Laverton Nickel Sulphide Project in Western Australia (“St George’s Project” or “the Project”), has found that the Project represents a significant and de‐risked exploration opportunity. The review confirmed that the East Laverton Nickel Project has the size and necessary geological criteria to host multiple nickel sulphide deposits, establishing it as a potential new and emerging nickel camp.

The Technical Review, led by global nickel expert Dr Jon Hronsky, has highlighted an 18km strike length of the Stella Range belt ‐ which covers the Desert Dragon and Windsor prospects ‐ as being the most prospective area for nickel sulphide mineralisation within the Project tenements (see Figure 1). Strong similarities exist between the geological setting and features of this area and those of highly mineralised komatiite hosted nickel sulphide belts, particularly the Forrestania and the Agnew‐Wiluna belts in the Yilgarn Craton.

The Review also highlights the extensive strike length of basal contact present within this area, and how this prospective surface has been significantly extended by the complex folding which was once linear in nature. Only a small section of the prospective basal contact of this target area has been drill tested to date, possibly as little as 5%, with substantial exploration upside remaining.

Immediate drill targets in this area have been identified, and further exploration is strongly recommended.

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

“The top‐down approach of the Technical Review has recognised and confirmed the presence at our Project of the important geological criteria for large scale nickel sulphide mineralisation.

“This opinion is based on a substantial amount of empirical data – this is no longer just a concept.

“The Review is now focused on target generation with several high quality targets already identified for immediate drilling.

”These are new and inspiring targets and we start test drilling them later this month.”

EAST LAVERTON PROPERTY – ATTRACTIVE FEATURES AT THE REGIONAL SCALE Underexplored Nickel Belt

St George’s East Laverton Property is located within the East Laverton nickel belt, an extensive komatiite belt in the north east of the Yilgarn Craton, which hosts numerous nickel sulphide deposits (see Figure 2).

The belt encompasses the Fisher East (Camelwood) project of Rox Resources (ASX: RXL) in the north, the Rosie project of Duketon Mining (ASX: DKM) and the Windarra mine of Poseidon Nickel (ASX: POS) in the centre of the belt, and St George’s East Laverton Project in the southern end of the belt.

The nickel potential at St George’s East Laverton Property has only been recently recognised, due primarily to extensive post mineral cover. New exploration concepts and modern methods have driven more effective exploration in these conditions, resulting in a rapid progression of several discoveries of nickel sulphides, which have justified a strategy for camp-scale nickel exploration.

Major Mining Company Interest

The large scale potential at St George’s Project has attracted the attention of major mining companies, with the first nickel focused exploration campaign at the Project being completed by BHP Billiton Nickel West in 2012 under the Project Dragon farm‐in arrangement with St George. Following completion of a successful drilling campaign in 2012 which discovered nickel sulphides at the Project, BHP Billiton Nickel West exercised an option to continue the farm‐in and potentially earn up to 70% of the Project by completing a bankable feasibility study.

BHP Billiton Nickel West subsequently withdrew from the Project for corporate reasons, but the credentials of the Project as a potential large scale nickel camp were firmly established.

The local geology of St George’s Project displays some particularly favourable aspects in terms of nickel sulphide prospectivity, and these are discussed below.

KEY NICKEL SULPHIDE CRITERIA – ALL PRESENT AT EAST LAVERTON PROJECT

Rare High MgO Komatiites ‐ Increased Nickel Endowment

The favourable conditions present at St George’s Project are reflected in thick sequences of komatiites that have estimated volatile‐free MgO levels up to 54% and Mg numbers up to 93. This indicates the komatiites were formed from very magnesian rich parental liquids (probably about 30% MgO).

The high temperature, high MgO komatiites present at St George’s Project appear to be a localised feature, and suggest the potential for a much higher nickel endowment in the southern end of the East Laverton nickel belt, where St George has the dominant land holding.

These high MgO komatiites reflect a core area of komatiite magmatism controlled by major crustal and sub‐ crustal structures that have allowed the transport and deposition of high volumes of very hot komatiites at high flow rates. This is a primary requisite for large nickel sulphide deposits.

Unique Komatiite Facies – Favourable Change at St George’s Boundary

The geological environments of the domains to the north of St George’s ground demonstrate a notable relationship between the komatiites and BIF (Banded Iron Formation) facies sediments, which form on the ultramafic contacts. (Facies is a term used to describe the character of a rock expressed by its formation, and its mineral and geochemical composition.)

More specialised conditions exist at St George’s Project where the komatiites, which have been shown to host nickel sulphides, have extremely sulphidic and metal‐rich (i.e. Cu + Zn) sediments on their margins. The regional change between the sulphide and BIF sediment facies occurs immediately north of St George’s East Laverton Property, likely controlled by a significant NE‐SW cross rift structure (see Figure 3).

The localised sulphide‐rich sedimentary facies at the Project has important implications for nickel sulphide endowment. This style of sediment indicates localised conditions where a hotter, deeper depositional environment is present, with greater availability of sulphur to form nickel sulphide mineralisation. This is also consistent with the previously noted presence of high MgO komatiites.

In this respect, St George’s ground is very similar to Forrestania and the nickel camps of the Agnew‐Wiluna belt, where more sulphur‐rich sediments are often intimately associated with nickel sulphide mineralisation.

Figure 3 – Key features of St George’s Project are shown over TMI magnetics. The regional facies change is interpreted to occur at the boundary illustrated to the north of the Project area. This change is likely to be very significant, indicating a hotter, deeper depositional environment to the south of the boundary with greater availability of sulphur to form nickel sulphide mineralisation.

Felsic‐Komatiite Rocks – An Ideal Host for Nickel Sulphide Belts

The Stella Range area is characterised by felsic schist wall rocks that are likely to represent deformed felsic volcanic or volcanoclastic sedimentary rocks. Petrographic studies have shown that any flanking mafic rocks at the Stella Range are part of the fractionated komatiite sequence and are not a separate volcanic basalt phase.

In the Yilgarn, the Felsic‐Komatiite association is relatively uncommon compared to the Mafic‐Komatiite association. The Felsic‐Komatiite association, where it does occur, is known to be associated with the majority of the well‐mineralised nickel camps, including Forrestania and the large Leinster camp in the Agnew‐Wiluna belt.

A Felsic‐Komatiite association reflects conditions where the felsic footwall rocks are more easily assimilated by komatiite lava (i.e. by thermal channelling) than would occur with more mafic compositions. Felsic volcanic lavas tend to not flow far from their volcanic vent, so the presence of felsic volcanic complexes are therefore localised and could indicate proximity to a major and prospective magmatic centre.

Known Nickel Sulphides

Drilling at St George’s Project has already encountered multiple occurrences of magmatic nickel sulphides. DRAC38 was the discovery hole at the Windsor prospect, and intersected 2 m @ 0.62 %Ni from 132m. This higher grade intersection was within a broad nickel zone of 30m @ 0.31%Ni from 108 m. A petrographic examination of nickel sulphides in this intersection confirmed the only sulphide present was pentlandite, a high tenor nickel sulphide.

‘Nickel tenor’ is the nickel content of the sulphide portion of the rock, calculated on the basis of 100% sulphide. This is different than grade, which is the amount of a metal in a mass of rock, expressed as a percentage, or as grams per tonne (g/t). High tenor nickel sulphides have lesser amounts of iron and copper. This is of benefit for the economic viability of any mineralisation present as it means any sulphide concentrate will be high grade.

The presence of high tenor nickel sulphides at the East Laverton Property is further evidence of the potential nickel endowment and prospectivity of St George’s Project as it implies a large and dynamic magmatic system, favourable for nickel sulphide mineralisation.

Favourable Structural Architecture

A key feature of large and well‐mineralised nickel camps is favourable sub‐crustal and crustal rift architecture, which controls the distribution of komatiite volcanism and nickel sulphide deposition.

Typically, this architecture involves deep rifts controlled by rift parallel faults that are cross‐cut by major transform faults. Rift parallel faults are the large regional NW‐NNW trending shear zones. The transform (or rift normal) faults are early and fundamental structures that become more cryptic in nature as they are obscured by overlying stratigraphy and late local faults developed in these covering rocks.

The intersections of these structures are areas that experience higher volumes, higher temperatures and higher flow rates of komatiite magma, creating enhanced conditions for nickel sulphide deposition. These important areas are associated with greenstone depocentres.

A depocentre is an area which is the thickest and deepest part of the komatiite‐hosting rift. Large gravity anomalies are interpreted to represent local greenstone depocentres at East Laverton. This is because of the preferential concentration of high density greenstone rocks, the location of which is controlled by NE‐ trending cryptic transfer structures such as the Churchill Lineament at St George’s Project.

Major nickel deposits are known to form in proximity to the intersection of these rift parallel and rift normal cross structures, including the Perseverance, Mt Keith and Cliffs deposits in the Agnew‐Wiluna belt, especially in proximity to their associated depocentres.

This favourable structural architecture is present at St George’s East Laverton Project, where the main NNW trending rift‐parallel structures are intersected by the more cryptic NE trending transform faults; see Figure 4. The architecture is very prominent in the Desert Dragon‐Windsor prospect area where a major depocentre is observed.

Figure 4 – Fundamental rift architecture is prominent at St George’s Project with major NNW fault zones cross cut by cryptic transfer structures like the Churchill Lineament. Known nickel sulphides and high‐MgO komatiite channels are closely associated with the intersection of these structures. This architecture is very similar to the structural architecture seen at highly mineralised komatiite hosted nickel camps including at Forrestania and in the Agnew‐Wiluna belt.

The Technical Review has developed an exploration model that targets a 5km zone around the intersection of the structures. Drilling results at the Project to date show that these target zones host the majority of known high‐MgO ultramafic channels as well as all nickel sulphide intersections; see Figure 5.

These results are an excellent fit to this exploration model, and provide encouragement to focus the search for massive nickel sulphides in these areas.

In summary, the Technical Review has highlighted that the East Laverton Property has some specialised and very favourable geological features which confirm the compelling exploration prospectivity of St George’s Project.

Figure 5 – This map highlights the key targeting criteria at St George’s Project, as well as the regional tectonic targets which are interpreted to be within 5km of the intersection of the NNW fault zones with the NE cryptic transforms. All seven targeting criteria are strongly supportive of the potential of large scale nickel sulphide mineralisation at the Project.

HIGH PRIORITY PROSPECTS IDENTIFIED

The Technical Review has selected the Desert Dragon‐Windsor domain along the Stella Range belt as the most prospective area for massive nickel sulphide deposits. Other target areas were also considered prospective for mineralisation, with Desert Dragon‐Windsor standing out as the highest priority for follow‐ up exploration.

The Desert Dragon‐Windsor area is approximately 18 km long and is a camp‐scale target area comparable in size to the major known nickel camps within the Agnew‐Wiluna belt such as Leinster and Honeymoon Well.

Four discrete prospect areas have been defined within the Desert Dragon‐Windsor camp (see Figure 6):

  • Desert Dragon North

  • Desert Dragon Central

  • Windsor North

  • Windsor

Figure 6 – the four key target areas within the emerging nickel camp at Desert Dragon‐Windsor are highlighted against a background of interpreted geology.

These prospects have undergone very limited drilling. There is a large extent of untested ultramafic contact at these prospects, with significant space remaining to fit in several major nickel sulphide deposits.

The Technical Review has identified immediate drill targets at each of these prospect areas. In addition, Newexco – the Company’s geophysical adviser – has identified a number of strong late‐time electromagnetic (EM) conductors at Desert Dragon‐Windsor including four Category 1 anomalies that were recently identified at Desert Dragon.

ASX / MEDIA RELEASE

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

Detailed planning is underway to determine optimal positions for drill testing of these targets. This targeting work includes a review of the existing drill hole data in the context of the new project scale interpretation provided by the Technical Review. This will permit enhanced geological interpretations from the expanded database. A further announcement will be made once these drill targets are completed.

A strong pipeline of drill targets will be established once this interpretative and targeting work is completed.

Two of the immediate drill targets identified by the Technical Review are at Desert Dragon, and these are discussed below.

DESERT DRAGON – HIGH QUALITY TARGETS FOR MASSIVE NICKEL SULPHIDES Desert Dragon North – Finding the Primary Source for Remobilised Nickel

Drill hole DDNRC002 was completed by St George at Desert Dragon North in 2012 and intersected 2m @ 1.08%Ni from 55m, in the form of massive sulphide stringer veins.

Geological interpretation indicates the ultramafic block hosting this significant intersection was mechanically remobilised from a local source. The ultramafic at DDNRC002 is in contact with a shear zone, which would have remobilised the nickel sulphides.

The komatiite channel immediately north of DDNRC002 remains completely untested, including two EM plates associated with the channel. The area is a particularly favourable structural site for nickel sulphide accumulation, adjacent to the intersection of a NE trending (cross rift) structure within the northerly trending Stella Range fault (see Figure 7).

An EM conductor to the north of DDNRC002 appears to be connected to the mineralisation intersected in this drill hole by a shear zone and is a compelling target as the possible source of the massive nickel sulphides in DDNRC002 (see Figure 8).

Desert Dragon Central – EM Conductors Co‐incident with Basal Contact and Gravity Anomalies

Desert Dragon Central is in a part of the Stella Range belt which has undergone complex folding and shearing, which may have resulted in the structural concentration of massive nickel sulphide mineralisation in fold noses.

Drill hole DRAC35 was completed at Desert Dragon by BHP Billiton Nickel West in 2012 and intersected 18m @ 0.40%Ni from 100m (including 4m @ 0.57%Ni from 100m). The favourable structural features, known mineralisation and very limited drilling to date, make this an attractive prospect for exploration.

Two immediate drill targets have been identified in this area: see Figure 9. Target 1 is a discrete strong gravity anomaly, indicating dense rocks such as sulphide‐rich accumulations. The anomaly is along strike from DRAC35 and adjacent to an EM plate that is modelled on the western ultramafic contact, factors which further support the potential for nickel sulphide mineralisation.

Target 2 is also a discrete strong gravity anomaly which is co‐incident with an untested EM conductor located on the interpreted ultramafic contact, a typical setting for nickel sulphide mineralisation.

Both of these targets are believed to represent sulphide‐rich accumulations that could contain massive nickel sulphides or VMS‐style deposits.

ST GEORGE BOOSTS TECHNICAL TEAM

The leader of the Technical Review, Dr Jon Hronsky, is a global nickel expert with industry leading credentials in the area of exploration targeting for nickel sulphide deposits. Dr Hronsky will continue to consult with St George with the aim of developing further drill targets at the East Laverton Project.

ASX / MEDIA RELEASE

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

Matthew McCarthy, formerly a Senior Geologist with BHP Billiton Nickel West, also contributed to the Technical Review and will continue his work with St George as required.

St George has also retained the consulting services of Ms Barbara Duggan, who has over 10 years of international exploration experience predominantly in nickel systems and Archaean gold deposits with a particular focus on target generation and mineralisation vectoring in exploration. As part of INCO Exploration's project generation group and then with BHP Billiton Nickel West, she targeted and explored for nickel deposits in Sudbury, Voisey's Bay, Thompson and the Agnew‐Wiluna belt and has been involved with the discovery of over 1Mt of nickel in her career.

Ms Duggan’s expertise will be particularly valuable in optimising the detailed interpretative work required to refine the drill targets generated by the Technical Review.

Newexco continues to act as geophysical adviser to St George, and will play an important role in target development through their expert interpretation and modelling of EM anomalies at our Project.

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

“The technical team that we have assembled has a strong record in nickel sulphide discoveries.

“Their work on the Technical Review has already produced several new and compelling targets for immediate drill testing.

“Work on target generation is continuing and we expect a quality pipeline of drill targets to be established.

“The Technical Review has provided us with a roadmap to discovery.”

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

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.
