DRILLING SUCCESS CONTINUES AT MT ALEXANDER

HIGHLIGHTS:

  • Further massive nickel-copper sulphides discovered at the Investigators Prospect

  • Three more electromagnetic (EM) conductors successfully tested returning high grade massive nickel-copper sulphides with average grades of 7%Ni and 2.3%Cu (based on field XRF analysis)

  • Potential to further extend the known mineralisation in the Cathedrals Belt with at least another 14 planned drill holes

  • Downhole EM (DHEM) surveys are underway on the completed drill holes to investigate for extensions to mineralisation and to define conductive sources

  • Moving loop EM (MLEM) survey over the western extension of the Cathedrals Belt has identified anomalous EM responses proximal to the Ida Fault

  • Argonaut appointed as financial adviser to St George in regard to strategic opportunities to maximise value of the Mt Alexander Project

DRILLING SUCCESS CONTINUES AT THE MT ALEXANDER PROJECT

St George Mining Limited (ASX: SGQ ) (‘St George Mining’ or ‘the Company’) is pleased to announce that further massive nickel-copper sulphides have been discovered at the Investigators Prospect in the major drill programme currently underway at the Mt Alexander Project in Western Australia.

Three of the five drill holes completed to date have successfully tested three separate EM conductors. These drill holes - MAD43, MAD44 and MAD45 – have all intersected massive nickel-copper sulphides. The other two drill holes - MAD41 and MAD42 - intersected prospective ultramafic but not the target EM conductors. DHEM surveys are being completed in these drill holes to better define the location of the EM conductors, which were modelled from surface EM data.

The drill programme at Mt Alexander is continuing with 14 planned holes yet to be drilled, and additional drill holes likely to be added after the DHEM surveys. This important drill programme is on track to discover more high grade nickel-copper sulphides and to expand the mineralisation in the Cathedrals Belt.

St George’s continued exploration success at the Mt Alexander Project is presenting the Company with strategic M&A opportunities for development of the Project. St George has appointed Argonaut as its financial adviser to assist in pursuing strategic opportunities that maximise shareholder value.

St George Mining Executive Chairman, John Prineas said:

“The discovery of further high grade nickel-copper sulphide mineralisation at Investigators confirms the potential to significantly expand the known mineralisation at this prospect, where mineralisation has already been shown to be present recurrently over a strike length of 1.3km.

“We are very excited by this early success and the potential for more discoveries over the next few weeks.”

CONTINUED SUCCESS DRILLING EM CONDUCTORS

MAD43 tested an off-hole DHEM plate (MAD39 p_1) at Investigators and was drilled to a downhole depth of 180m. The drill hole has intersected a 10.2m thick ultramafic unit from 147.8m with nickel-copper sulphides summarised below :

  • a 9.42m thick interval, from 147.8m, of ultramafic with weak-moderate blebby and disseminated sulphides

  • a 0.73m thick interval, from 157.22m, of massive sulphides with spot XRF readings averaging 5.1%Ni and 2.15%Cu

MAD44 tested another DHEM plate (MAD39 p_2) at Investigators, located approximately 65m to the west of the DHEM plate tested by MAD43. MAD44 was also drilled to a downhole depth of 180m and has intersected:

  • 8.14m of ultramafic from 147.35m with rare disseminated sulphides

  • remobilised massive to semi-massive sulphides in granite just below the ultramafic contact from 155.69m to 156.11m. XRF readings of the massive sulphide shows variation in the nickel content from 5-6%Ni in the core to 27%Ni in the coarse grained pentlandite-rich rims

The massive sulphides in MAD44 are interpreted to have been remobilised from a proximal body of nickelcopper sulphide mineralisation. A DHEM survey will be completed in MAD44 next week to investigate for any conductive bodies around the drill hole that may represent the potential source of the mineralisation.

MAD45 tested SAMSON Anomaly 6 at Investigators. The drill hole intersected ultramafic from 165.2m downhole with the profile of the sulphide mineralisation intersected as follows:

  • weak disseminated and blebby sulphides from 171m to 174m

  • moderate blebby and disseminated sulphides from 174m to 178m

  • 0.88m of strong disseminated and matrix sulphides from 178m to 178.88m

  • 0.2m of massive sulphide from 178.88m to 179.08m, with spot XRF readings averaging 4%Ni and 0.1%Cu

  • 0.68m of matrix and strong disseminated sulphides from 179.08m to 179.76m, with spot XRF readings averaging 1%Ni and 0.03%Cu

  • 0.37m of massive sulphide from 179.76m to 180.13m, with spot XRF readings averaging 7.9%Ni and 2.9%Cu

Based on the intersection angle of the drilling and interpreted EM plates, the downhole widths are interpreted to be near to true widths, but will be reviewed again with DHEM survey results.

MAD43 and MAD44 drill holes are approximately 50m apart, and MAD45 is approximately a further 500m to the west of those drill holes. The discovery of further high grade mineralisation over such a broad area and associated with the same ultramafic unit at Investigators, supports the potential for further discoveries and extensions to the known mineralisation at Investigators.

The portable XRF analysis is showing high grades of nickel and copper in the mineralisation intersected by these drill holes. Laboratory assays will confirm these values and we expect the assays to also indicate high values of cobalt and PGEs consistent with previous high-grade mineralisation intersected in the Cathedrals Belt to date.

The MLEM survey has been completed over the new target area where the Cathedrals Belt intersects the Ida Fault. The intersection of these structures may have operated as a control of the mineralisation in the Cathedrals Belt.

Two anomalous EM responses have been detected in this area, and are being further evaluated in conjunction with our geophysical consultants Newexco.

CURRENT DRILL PROGRAMME

Table 1 shows drill hole details for drill holes both planned and completed in the current diamond drill programme. Drill hole MAD46 is currently being drilled.

In addition to MAD43, MAD44 and MAD45, two further drill holes have been completed – MAD41 and MAD42. These drill holes targeted the SAMSON Anomalies 7 and 8 at Investigators, respectively.

MAD41 was completed to a downhole depth of 237.9m, and targeted an EM plate modelled at a depth of 207m with conductivity of 15,000 Siemens. The drill hole intersected weakly mineralised ultramafic from 136.9-140.6m however did not intersect any material that could explain this very strong EM conductor.

ASX / MEDIA RELEASE

==> picture [119 x 55] intentionally omitted <==

MAD42 was completed to a downhole depth of 275m, and targeted an EM plate modelled at a depth of 244m with conductivity of 24,650 Siemens. This drill hole intersected two thin ultramafics around 190m however also did not intersect any material that could explain the very strong modelled EM conductor.

A DHEM survey will be completed in each of these drill holes to better define the EM responses for future drilling. Any off-hole EM conductors identified will be drilled in the current programme, which is scheduled to continue for 4 to 6 weeks.

The following sections are provided for compliance with requirements for the reporting of exploration results under the JORC Code, 2012 Edition.

Section 1 Sampling Techniques and Data

(Criteria in this section apply to all succeeding sections)

Criteria JORC Code explanation Commentary
Sampling
techniques
Nature and quality of sampling (eg cut
channels, random chips, or specific specialised
industry
standard
measurement
tools
appropriate
to
the
minerals
under
investigation, such as down hole gamma
sondes, or handheld XRF instruments, etc.).
These examples should not be taken as limiting
the broad meaning of sampling.
The sections of the core that are selected for assaying are marked
up and then recorded on a sample sheet for cutting and sampling at
the certified assay laboratory. Samples of HQ or NQ2 core are cut
just to the right of the orientation line where available using a
diamond core saw, with half core sampled lengthways for assay.
The MLEM survey will be conducted using 200x200m loops to
generate 100 amps, with a base frequency of 0.5Hz. Line spacing is
typically 200m and station spacing typically 100m. Survey will use a
fluxgate sensor.
Include reference to measures taken to ensure
sample representivity and the appropriate
calibration of any measurement tools or
systems used.
Wherever possible the same side of the drill core is sampled to
ensure sample is representative. Appropriate QAQC samples are
inserted into the sequences as per industry best practice.
Aspects of the determination of mineralisation
that are Material to the Public Report.
In cases where ‘industry standard’ work has
been done this would be relatively simple (eg
‘reverse circulation drilling was used to obtain
1 m samples from which 3 kg was pulverised to
produce a 30 g charge for fire assay’). In other
cases more explanation may be required, such
as where there is coarse gold that has inherent
sampling problems. Unusual commodities or
mineralisation types (eg submarine nodules)
may
warrant
disclosure
of
detailed
information.
Diamond core (both HQ and NQ2) is half‐core sampled to geological
boundaries no more than 1.5m and no less than 10cm. Samples less
than 3kg are crushed to 10mm, dried and then pulverised to 75µm.
Samples greater than 3kg are first crushed to 10mm then finely
crushed to 3mm and input into the rotary splitters to produce a
consistent output weight for pulverisation.
Pulverisation produces a 40g charge for fire assay. Elements
determined from fire assay are gold (Au), platinum (Pt) and
palladium (Pd) with a 1ppb detection limit. To determine other PGE
concentrations (Rh, Ru, Os, Ir) a 25g charge for nickel sulphide
collect fire assay is used with a 1ppb detection limit.
Other elements will be analysed using an acid digest and an ICP
finish. These elements are: Ag, Al, As, Bi, Ca, Cd, Co, Cr, Fe, K, Li, Mg,
Mn, Mo, Nb, Ni, P, Pb, S, Sb, Sn, Te, Ti, V, W, Zn. The sample is
digested with nitric, hydrochloric, hydrofluoric and perchloric acids
to effect as near to total solubility of the sample as possible. The
sample is then analysed using ICP‐AES or ICP‐MS.
LOI (Loss on Ignition) will be completed on selected samples to
determine the percentage of volatiles released during heating of
samples to 1000°C.
Drilling
techniques
Drill type (eg core, reverse circulation, open‐
hole hammer, rotary air blast, auger, Bangka,
sonic, etc) and details (eg core diameter, triple
or standard tube, depth of diamond tails, face‐
sampling bit or other type, whether core is
oriented and if so, by what method, etc).
Diamond drilling is completed using HQ sized coring equipment
through the weathered zone (mostly saprock) with 3m barrels, and
then HQ or NQ2 in fresh rock with 3m or 6m barrels as required. The
core is oriented using ACT II electric core orientation.
Drill sample
recovery
Method of recording and assessing core and
chip sample recoveries and results assessed.
Diamond core recoveries are recorded during drilling and reconciled
during the core processing and geological logging. The core length
recovered is measured for each run and recorded which is used to
calculate core recovery as a percentage.

1

Criteria JORC Code explanation Commentary
Measures taken to maximise sample recovery
and ensure representative nature of the
samples.
Measures taken to maximise core recovery include using
appropriate core diameter and shorter barrel length through the
weathered zone, which at Cathedrals and Investigators is mostly
<25m and Stricklands <45m depth. Primary locations for core loss in
fresh rock are on geological contacts and structural zones, and drill
techniques are adjusted accordingly, and if possible these zones are
predicted from the geological modelling.
Whether a relationship exists between sample
recovery and grade and whether sample bias
may have occurred due to preferential
loss/gain of fine/coarse material.
No sample recovery issues have yet been identified that would
impact on potential sample bias in the competent fresh rocks that
host the mineralised sulphide intervals.
Logging Whether core and chip samples have been
geologically and geotechnically logged to a
level of detail to support appropriate Mineral
Resource estimation, mining studies and
metallurgical studies.
Geological logging is completed for all drill holes with lithology,
alteration, mineralisation, structure and veining recorded. The
logging is recorded digitally and imported in the St George Mining
central database.
Whether logging is qualitative or quantitative
in nature. Core (or costean, channel, etc.)
photography.
Logging is both qualitative and quantitative depending on the field
being captured. Core is photographed with one tray per photo and
stored digitally.
The total length and percentage of the relevant
intersections logged.
All drill holes are geologically logged in full.
Sub‐sampling
techniques and
sample
preparation
If core, whether cut or sawn and whether
quarter, half or all core taken.
The HQ and NQ2 core is cut in half length ways just to the right of
the orientation line where available using a diamond core saw. All
samples are collected from the same side of the core where
practicable.
If non‐core, whether riffled, tube sampled,
rotary split, etc and whether sampled wet or
dry.
No non‐core holes where completed in the current drill program.
For all sample types, the nature, quality and
appropriateness of the sample preparation
technique.
The entire sample is pulverised to 75µm using LM5 pulverising mills.
Samples are dried, crushed and pulverized to produce a
homogenous representative sub‐sample for analysis. A grind quality
target of 90% passing 75µm is used.
Quality control procedures adopted for all sub‐
sampling stages to maximise representivity of
samples.
Quality control procedures include submission of Certified
Reference Materials (standards), duplicates and blanks with each
sample batch. QAQC results are routinely reviewed to identify and
resolve any issues.
Measures taken to ensure that the sampling is
representative of the in situ material collected,
including for instance results for field
duplicate/second‐half sampling.
Duplicate samples are selected during sampling. Samples comprise
two quarter core samples.
Whether sample sizes are appropriate to the
grain size of the material being sampled.
The sample sizes are considered to be appropriate for base metal
sulphide mineralisation and associated geology.
Quality of
assay data and
laboratory
tests
The nature, quality and appropriateness of the
assaying and laboratory procedures used and
whether the technique is considered partial or
total.
Diamond core samples are analysed for Au, Pt and Pd using a 40g
lead collection fire assay; for Rh, Ru, Os, Ir using a 25g nickel
sulphide collection fire assay; and for Ag, Al, As, Bi, Ca, Cd, Co, Cr, Fe,
K, Li, Mg, Mn, Mo, Nb, Ni, P, Pb, S, Sb, Sn, Te, Ti, V, W, Zn using a
four acid digest and ICP‐AES or MS finish. The assay method and
detection limits are appropriate for analysis of the elements
required.

Criteria JORC Code explanation Commentary
For geophysical tools, spectrometers, handheld
XRF instruments, etc, the parameters used in
determining the analysis including instrument
make and model, reading times, calibrations
factors applied and their derivation, etc.
A handheld XRF instrument (Olympus Innov‐X Spectrum Analyser) is
used to systematically analyse the drill core onsite. One reading is
taken per meter, however for any samples with matrix or massive
sulphide mineralisation then five to ten samples are taken at set
intervals per meter. The instruments are serviced and calibrated at
least once a year. Field calibration of the XRF instrument using
standards is periodically performed.
The handheld XRF results are only used for preliminary assessment
and reporting of element compositions, prior to the receipt of assay
results from the certified laboratory.
The MLEM survey will be conducted using 200x200m loops to
generate 100 amps, with a base frequency of 0.5Hz. Line spacing is
typically 200m and station spacing typically 100m. Survey will use a
fluxgate sensor.
Nature of quality control procedures adopted
(eg standards, blanks, duplicates, external
laboratory checks) and whether acceptable
levels of accuracy (i.e. lack of bias) and
precision have been established.
Laboratory QAQC involves the use of internal lab standards using
certified reference material (CRMs), blanks and pulp duplicates as
part of in house procedures. The Company also submits a suite of
CRMs, blanks and selects appropriate samples for duplicates.
Sample preparation checks for fineness are performed by the
laboratory to ensure the grind size of 90% passing 75µm is being
attained.
Verification of
sampling and
assaying
The verification of significant intersections by
either independent or alternative company
personnel.
Significant intersections are verified by the Exploration Manager of
St George Mining.
The use of twinned holes. No twin holes are planned in the current drill program.
Documentation of primary data, data entry
procedures, data verification, data storage
(physical and electronic) protocols.
Primary data is captured onto a laptop using acQuire software and
includes geological logging, sample data and QA/QC information.
This data, together with the assay data, is entered into the St
George Mining central SQL database which is managed by external
consultants.
Discuss any adjustment to assay data. No adjustments or calibrations will be made to any primary assay
data reported.
Location of
data points
Accuracy and quality of surveys used to locate
drill holes (collar and down‐hole surveys),
trenches, mine workings and other locations
used in Mineral Resource estimation.
Drill holes have been located and pegged using a DGPS system with
an expected accuracy of +/‐0.05mmm for easting, northing and
elevation.
Downhole surveys are conducted using a single shot camera
approximately every 30m during drilling to record and monitor
deviations of the hole from the planned dip and azimuth. Post‐
drilling downhole gyroscopic surveys will be conducted, which
provide much more accurate survey results.
Specification of the grid system used. The grid system used at the Mt Alexander project is GDA94 (MGA),
zone 51.
Quality and adequacy of topographic control. Elevation data has been acquired using DGPS surveying at individual
collar locations and entered into the central database. A
topographic surface has been created using this elevation data.
Data spacing
and
distribution
Data spacing for reporting of Exploration
Results.
The diamond drill program is testing modelled EM conductors and
geological
criteria
for
massive
nickel‐copper‐PGE
sulphide
mineralisation. The spacing and distribution of the drill holes is
appropriate to test the defined targets.
The MLEM survey will be conducted on a 200m line spacing with
100m stations. If an anomaly is detected, then infill surveys will
typically use 100m line spacing with 50m stations.

3

Criteria JORC Code explanation Commentary
Whether the data spacing and distribution is
sufficient to establish the degree of geological
and grade continuity appropriate for the
Mineral Resource and Ore Reserve estimation
procedure(s) and classifications applied.
The completed drilling at Cathedrals, Stricklands and Investigators is
not sufficient to establish the degree of geological and grade
continuity to support the definition of Mineral Resource and
Reserves and the classifications applied under the 2012 JORC code.
Whether sample compositing has been applied. No compositing has been applied to the exploration results.
Orientation of
data in relation
to geological
structure
Whether the orientation of sampling achieves
unbiased sampling of possible structures and
the extent to which this is known, considering
the deposit type.
Drill holes are planned as perpendicular as possible to the target EM
plates to approximate true width. Most of the ultramafic units in the
Cathedrals Belt dip shallow to the north and where possible drill
holes have been planned to intersect perpendicular to dip. The
orientation of key structures may be locally variable.
If the relationship between the drilling
orientation and the orientation of key
mineralised structures is considered to have
introduced a sampling bias, this should be
assessed and reported if material.
No orientation based sampling bias has been identified in the data
to date.
Sample
security
The measures taken to ensure sample security. Chain of custody is managed by St George Mining. Core samples are
stored in the secure facilities at Bureau Veritas laboratory in Perth.
Transportation of core is managed by St George contractors and
Bureau Veritas and actively track monitored.
Audits or
reviews
The results of any audits or reviews of sampling
techniques and data.
No audits or reviews have been conducted at this stage.

The security of the tenure held at the time of
reporting along with any known impediments
to obtaining a licence to operate in the area.
The Mt Alexander Project is comprised of four granted Exploration
Licences (E29/638, E29/548, E29/954 and E29/962). Tenement
E29/638 is held in Joint Venture between St George (75% interest)
and Western Areas (25% interest). E29/638 and E29/548 are also
subject to a royalty in favour of a third party that is outlined in the
ASX Release dated 17 December 2015 (as regards E29/638) and the
ASX release dated 18 September 2015 (as regards E29/548).
No environmentally sensitive sites have been identified on the
tenements. A registered Heritage site known as Willsmore 1 (DAA
identification 3087) straddles tenements E29/548 and E29/638. All
four tenements are in good standing and no known impediments
exist.
Exploration
Done by Other
Parties
Acknowledgment and appraisal of exploration
by other parties.
Exploration on tenements E29/638 and E29/962 has been largely for
komatiite‐hosted nickel sulphides in the Mt Alexander Greenstone
Belt. Exploration in the northern section of E29/638 (Cathedrals
Prospect) and also limited exploration on E29/548 has been for
komatiite‐hosted Ni‐Cu sulphides in granite terrane. No previous
exploration has been identified on E29/954.
The target lithological unit in the Mt Alexander Greenstone belt has
historically been the Central Ultramafic Unit, which has been
explored by a number of parties, most recently by Nickel West.
High grade nickel‐copper sulphides were discovered at the Mt
Alexander Project in 2008. Drilling was completed to test co‐incident
electromagnetic (EM) and magnetic anomalies associated with
nickel‐PGE enriched gossans in the northern section of current
tenement E29/638. The drilling identified high grade nickel‐copper
mineralisation in granite‐hosted ultramafic units and the discovery
was named the Cathedrals Prospect. The tenements remain
underexplored.

to the west by the Ida Fault, a significant Craton‐scale structure that
marks the boundary between the Kalgoorlie Terrane (and Eastern
Goldfields Superterrane) to the east and the Youanmi Terrane to the
west.
The Mt Alexander Project is prospective for further high‐grade
komatiite‐hosted
nickel‐copper‐PGE
mineralisation
(both
greenstone and granite hosted) and also precious metal
mineralisation (i.e. orogenic gold) that is typified elsewhere in the
Yilgarn Craton.
Drill hole
information
A summary of all information material to the
understanding of the exploration results
including
tabulation
of
the
following
information for all Material drill holes:
• Easting and northing of the drill hole collar
•Elevation or RL (Reduced Level – elevation
above sea level in meters) of the drill hole collar
• Dip and azimuth of the hole
• Down hole length and interception depth
• Hole length
Drill hole information is shown in Table 1 in the body of the release.
Data
aggregation
methods
In reporting Exploration Results, weighting
averaging
techniques,
maximum
and/or
minimum grade truncations (e.g. cutting of
high grades) and cut‐off grades are usually
Material and should be stated.
Reported assay intersections are length and density weighted.
Significant intersections are determined using both qualitative (i.e.
geological logging) and quantitative (i.e. lower cut‐off) methods.
For massive sulphide intersections, the nominal lower cut‐off is 2%
for either nickel or copper. For disseminated, blebby and matrix
sulphide intersections the nominal lower cut‐off for nickel is 0.3%.
Where aggregated intercepts incorporate short
lengths of high grade results and longer
lengths of low grade results, the procedure
used for such aggregation should be stated and
some typical examples of such aggregations
should be shown in detail.
Any high‐grade sulphide intervals internal to broader zones of
sulphide mineralisation are reported as_included_intervals.
For example, any heavy disseminated or matrix sulphides with >1%
nickel or copper directly on contact with massive sulphide
mineralisation are grouped with the massive sulphides for
calculating significant intersections and the massive sulphide
mineralisation is reported as an_including_intersection.
The assumptions used for any reporting of
metal equivalent values should be clearly
stated.
No metal equivalent values have yet been used for reporting
exploration results.
Relationship
between
mineralisation
widths and
intercept
lengths
These relationships are particularly important
in the reporting of exploration results.
If the geometry of the mineralisation with
respect to the drill hole angle is known, its
nature should be reported. If it is not known
and only the down hole lengths are reported,
there should be a clear statement to this effect
(e.g. down hole length, true width not known).
Assay intersections are reported as down hole lengths. Drill holes
were planned as perpendicular as possible to intersect the target
EM plates so downhole lengths are interpreted to be near true
width. Results from recent and ongoing drill programs will be
reviewed further to confirm the relationship between downhole
lengths and true widths.
Diagrams Appropriate maps and sections (with scales)
and tabulations of intercepts should be
included for any significant discovery being
reported. These should include, but not be
limited to a plane view of drill hole collar
locations and appropriate sectional views.
A relevant map of the Investigators Prospect and also the Cathedrals
Belt is shown in the body of the release.
Balanced
Reporting
Where
comprehensive
reporting
of
all
Exploration
Results
is
not
practical,
representative reporting of both low and high
grades and/or widths should be practiced to
avoid misleading reporting Exploration Results.
The exploration results reported are representative of the
mineralisation style with grades and/or widths reported in a
consistent manner.

exploration
data
Other exploration data, if meaningful and
material, should be reported including (but not
limited to): geological observation; geophysical
survey results; geochemical survey results; bulk
samples – size and method of treatment;
metallurgical
test
results;
bulk
density,
groundwater,
geotechnical

potential
deleterious
or
contaminating substances.
All material or meaningful data collected has been reported.
Further Work The nature and scale of planned further work
(e.g. tests for lateral extensions or depth
extensions or large – scale step – out drilling).
Diagrams clearly highlighting the areas of
possible
extensions,
including
the
main
geological interpretations and future drilling
areas, provided this information is not
