ASX ANNOUNCEMENT

ASX: VXL & VXLO

5 May 2015

50% INCREASE IN ULEY GRAPHITE RESOURCE

  • Material increase in contained graphite in Uley Pit 2 to 520,000t

  • Very high graphite grade maintained at 11.63% graphitic carbon

  • 68% of Mineral Resource is in the higher certainty Measured and Indicated categories

  • Mineralisation continues up-plunge and remains open along strike and at depth

  • Updated Uley Pit Ore Reserve due in May 2015

  • This update is based only on 48% of planned drilling program, confirming potential to easily increase reserves based on the well understood geological setting

  • Drill campaign for remaining 52% of program recommenced across southern area of Uley Pit 2

Valence Industries Limited (the ‘Company’) is very pleased to announce a material upgrade to the Mineral Resource estimate at its wholly owned Uley Pit 2 project in South Australia.

The updated JORC 2012 Mineral Resource for Uley Pit 2 is:

  • April 2015 estimate, reported using a 3.5% Graphitic Carbon cutoff for reporting purposes. Graphitic Carbon Grade tonnage distributions subdivided by JORC Code 2012 Resource Categories using rounded figures

  • Measured and Indicated Mineral Resource of 3.11 Mt at 12.1%gC (graphitic Carbon) and an Inferred Resource of 1.44 Mt at 10.6%gC (both at 3.5% Cut-off grade) ensures continuity of product supply for long term sales contracts.

  • An 88% increase in Inferred contained tonnes within the area of Uley Pit 2 and the current development drill-out progressing up-plunge and south along strike. This sees the resource moving increasingly towards surface as drilling moves south and supports expediting planning for a Uley Pit 2 cutback as shown by the new Inferred Mineral Resource tonnage estimate of 1.44M at 10.6%gC.

  • The latest drilling program has further confirmed continuity of near surface, high grade graphite within a simple and well understood geological setting, moving 41% of the previous Inferred resource to the Indicated resource category.

  • High-grade graphite mineralisation is present at the surface as soft clays, which will enable product value to be harnessed through a simple washing process rather than complex process engineering.

Christopher Darby, CEO & Managing Director Valence Industries, commented:

This material resource upgrade strongly supports the program to expand processing capacity at our Uley Graphite operations and matches the level of demand from our customers. At the same time, increasing the size of our resource supports the confidence being shown in the company by its financiers as we move to accelerate the significant expansion program under our Feasibility Study.

Uley Pit 2 Project

Diamond core drilling during late 2014 at the Uley Pit 2 project comprised 57 diamond core holes at a nominal spacing of 25m X 25m and 25m X 50m. Of those 57 diamond core holes assays have been completed for a total of 4,305m to which this update relates. (See ASX announcements dated 12/3/2015, 17/11/2014 and 1/09/2014 for further information). Infill drilling within the optimised pit was completed and selected wider spaced drilling immediately south of the pit is also included in this resource. (Figure 1)

The Mineral Resource estimate now includes the additional information gained from this drilling. An increase in total Mineral Resource of 50% which includes a 44% increase in the contained graphitic Carbon tonnes from the previous estimate. This includes an increase of 41% in contained tonnes reporting to the Measured and Indicated categories, and an additional 88% in contained Inferred tonnes gained through drilling along strike to the South of the proposed Uley Pit 2. (Figure 1)

During May 2015 an interim ore reserve, update will be released. While there is a 44% increase in the measured and indicated contained resource, the interim ore reserve increase is not expected to present a proportional increase, as the drilling in the south west is currently wider spaced and not complete, which means that pit designs for reserves cannot currently be finalised in that area. However, on completion of all drilling in the 2015 drilling campaign Valence Industries would expect a significant ore reserve increase in September 2015.

Drilling Program Metres of Drilling % of Total Drilling
2014 Mineral Resource: 4,080 31%
This 2015 Mineral Resource Interim update: 4,305 33%
2015 Mineral Resource final update: 4,695 36%
2015 Uley Pit 2 & Uley Pit 2 Extension: 13,080 100%

Current Drilling Campaign

The 2015 drilling campaign covers 9,000 metres of drilling. To date only 57 drill holes in the planned drilling campaign, for 97 drill holes, has been completed and 40 drillholes remain to be drilled and assayed. It is expected that results from this drilling and assay program will be reported periodically in the coming weeks as further assays are received.

Significantly, mineralisation remains open along strike to the south of the current resource and is also open at depth. The stronger geophysical response reported in previous releases continues to be a significant indicator of higher-grade areas of mineralisation. The strike continuity is the focus

of the current drilling campaign which is underway to the South of the Uley Pit 2 resource area. This drilling program is being undertaken on a nominal 25m X 25m pattern (Figure 2 and Figure 3) and will allow:

  • Proof of continuity of mineralisation to the south of the existing mining lease and well into the wholly owned exploration tenure.

  • An increase in resource confidence on the Inferred portion of the existing estimate, allowing a conversion to Ore Reserve once an optimisation on the resource has been completed

  • Further technical marketing with respect to significant supply upside on pre-qualified Uley Graphite [TM] products.

Figure 3: 2015 drilling along Exploration Target Uley Pit 2 (TEM geophysical signature)

Exploration Target

In addition to the updated mineral resource, the Company has estimated a significant Exploration Target (Figure 3) immediately to the south of Uley Pit 2[1] , in accordance with s17 of the JORC Code:

Tonnes of graphite 9.0Mt to 12.0Mt Grade of graphitic Carbon 9% to 12%

The Company cautions that the Exploration Target is conceptual in nature. The Exploration Target estimation is an expression of the potential for geological extensions to the Uley Pit 2 prospect based on prior work by third parties and interpretation of that data by Valence Industries. There has been insufficient exploration to estimate a Mineral Resource on the extension and it is uncertain if further exploration will result in the determination of a Mineral Resource on the extension.

The Company notes that the work in relation to the Exploration Target has relied upon historic data from open file and archived reports and the information relied upon cannot be duplicated or otherwise verified by the Company. The estimate made here is an Exploration Target under JORC 2012 Clause 17.

1 In establishing the Exploration Target cross sectional area calculations have been based on assumed strike and dip continuity of the estimated mineralisation in the proposed Uley Pit 2. Polygonal volume estimates were prepared applying a nominal bulk density of 1.91t/m3. Wireframes were developed in Vulcan software and clipped to a detailed topographic survey.

Notes:

The Uley Project is located on the Eyre Peninsula, 15km west-southwest of Port Lincoln in the state of South Australia.

Graphite mineralisation is hosted by folded and thrust graphitic schists and gneisses.

The deposit is covered by 25m x 25m spaced diamond drillholes. 30 of these are vertical and the remaining 41 drillholes are angled
at -60° to 090°

Validated data from 70 diamond drillholes has been used in the resource estimate.

Drillhole data was used to create wireframes of the mineralised zones utilising a 3.5% Graphitic C lower cut-off.

Low grade interpretations have been omitted as advice is that recovery of graphite is problematic from this material.

Drillhole logging data was used to create a surface of the base of oxidation and top of fresh rock. These have been used to inform
the block model though was not used in tabulating the resource.

Graphitic C assays and non-carbonate assays were used in the estimation. For the purpose of the estimation, Coffey have assumed
the Non-carbonate C is comprised primarily of graphite. Study of core photos, drill logs and petrography reports do not suggest
the presence of any non-elemental carbon within the non-carbonate C. Comparison of non-carbonate C and graphitic C assays
show the difference between the two techniques is less than the analytical error of the assay techniques.

Previous reports note that assays are of +75µm screened material for samples from the 18 drillholes drilled in 1993. Records of
weights for the sieved fractions have not been recovered and hence tonnages relying on data from these holes have not been
corrected. Assays from all other samples were taken from complete samples.

QAQC for the earlier drilling consists of umpire duplicates of early samples. No blanks or standards have been used in the sampling
protocols. No potential samples were highlighted by the umpire assays and they are considered to be acceptable for use in the
Resource estimation. QAQC for the 2014 programme consists of the insertion of certified standards at a rate of 1 in 25 and the
assaying of bulk reject duplicates at a rate of ~1 in 100. No problems were highlighted by the QAQC results.

The severely selectively sampled holes from the 2011 drilling programme have been relogged so that there are lithological records
for the entire holes. The visibly mineralised core that was not previously sampled has been sampled. The average grade of these
samples is 8.04% Graphitic C.

Both the resampling of the 2011 drillholes and the sampling of the 2014 drillholes have been selective, with only visibly graphitic
material sampled. In all, 52% of drilled core has been sampled. The selective sampling remains potentially problematic in several
areas.

Drill core was sampled on geological units ranging between 0.3m and 4m in length with the majority of sample lengths being 1m.
These have been composited to 1m intervals for the Resource estimate.

Statistical analyses were completed on the raw sample data and the 1m composite data. A top cut of 50% Graphitic C was applied
to the composites in the mineralised zones in the footwall (FW) and hangingwall (HW) domains, and a top cut of 30% Graphitic C
was applied to the composites in the flat lying/near surface domain.

Directional variograms were generated for composite data from both the FW and HW domains and variogram models created. As
the flat lying domain contained insufficient samples to conduct variography, parameters from the FW domain were applied to the
flat lying domain with adjusted orientation.

Grade estimates were generated for parent blocks of size 12.5m (X) x 12.5m (Y) x 4m (Z) with sub-blocks of size 1.25m x 1.25m x
1m. The method used to obtain grade estimates was Ordinary Kriging (OK).

In situ dry bulk densities were assigned on the basis of 371 measurements made from 22 drillholes from the 2014 programme. It
should be noted that the quantity of bulk density data has improved substantially, and revised and essentially lower bulk densities
applied to graphite mineralisation are the result of the Valence data. This change is likely to be related to a higher level of
weathering of the host rock than was previously understood.

Resource classification was developed from the confidence levels of key criteria including drilling methods, geological
understanding and interpretation, sampling, data density and location, grade estimation and quality of the estimates. The
resource classification and estimate does not specifically address the definition or quantity of material types or product quality as
all contacts are relatively gradational and metallurgical testwork is on-going.

A graphitic carbon cutoff of 3.5% was adopted based on a graphite product price of $1,500/t, a processing cost of $28.50/t, a
coarse fraction of 70% and an overall recovery of 90%. The values of 70% coarse fraction (>75μm) and 90% recovery have come
from review of two testwork programmes carried out on Uley ore samples in April and May 2007 and another programme carried
out in August 2014.

Person
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.

Include reference to measures taken to
ensure sample representivity and the
appropriate calibration of any measurement
tools or systems used.

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 1m samples from which 3kg was
pulverised to produce a 30g 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.

All holes used in the Resource Estimate were HQ
diamond drillholes sampling moderately dipping
stratabound graphite mineralised zones.

30 vertical drillholes were used in the estimate
together with 40 drillholes drilled at -60°
towards 090.

Half cores samples were obtained on geological
intervals, typically 1m in length but ranging from
0.3m to 4m.

High grade graphite mineralisation is reasonably
visible during geological logging and sampling.

Visibly mineralised intervals were crushed and
pulverised to at least 85% passing 75μm, then
sent for analysis by LECO method.

The sample preparation and assaying techniques
are industry standard and appropriate for this
type of mineralisation.

Some core material remains selectively sampled.
KL
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).

All holes used in the Resource Estimate were
drilled from surface.

30 drillholes were drilled using HQ standard tube
and were not orientated.

42 angled drillholes were drilled using HQ triple
tube. Downhole surveys were obtained using a
Ranger SS118 downhole camera. The angled
drillholes were orientated using the Reflex ACT II
RD core orientation tool.
KL
Drill sample
recovery

Method of recording and assessing core and
chip sample recoveries and results assessed.

Measures taken to maximise sample
recovery and ensure representative nature
of the samples.

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.

Core recovery was captured by logging “Core
Loss” in areas of no/low recovery.

Industry standard procedures/techniques were
employed
to
ensure
maximum
downhole
recovery. Overall core recovery for all resource
drillholes is 85%.

There has been no identified relationship
between sample recovery and grade.
KL
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.

Whether logging is qualitative or quantitative
in nature. Core (or costean, channel, etc)
photography.

The total length andpercentage of the

Geological and geotechnical logging of the
drillholes is of an appropriate standard to
support a Mineral Resource estimation, mining
studies and metallurgical studies.

Geological core logging is qualitative.

Core photography is available.

The total length of the samples intervals for all
holes used in the estimate was 3,420m (52% of
total core was sampled)

relevant intersections logged.
Sub-sampling
techniques
and sample
preparation

If core, whether cut or sawn and whether
quarter, half or all core taken.

If non-core, whether riffled, tube sampled,
rotary split, etc and whether sampled wet or
dry.

For all sample types, the nature, quality and
appropriateness of the sample preparation
technique.

Quality control procedures adopted for all
sub-sampling stages to maximise
representivity of samples.

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.

Whether sample sizes are appropriate to the
grain size of the material being sampled.

Half core samples were taken. In competent
core these were cut by core saw. In incompetent
material the sample was collected by manual
halving of the material. Half core sampling is an
appropriate, industry standard technique.

Bulk reject duplicate samples were taken in the
42
angled
drillholes
to
ensure
sample
representivity. These duplicates were inserted
at a typical frequency of 1 in 100 samples (1%
rate of insertion). Certified reference standards
were inserted at a typical rate of 1 in 20 samples
(5% rate of insertion) for quality assurance
checks of analyses reported by the mineral
testing laboratory ALS Global.

There is no record of field duplicate samples or
standards having been submitted in the 30
vertical
drillholes
to
test
sampling
representatively.

Samples from the 18 vertical 1993 drillholes
were crushed and sieved on site prior to
dispatching the coarse +75μm to ALS-Chemex for
assaying. There is no available data on weights
of sieved fractions. If the fine fraction was a
significant proportion of the sample, assays from
the coarse fractions should be higher than
corresponding whole rock assays. A study of
grades from the1993 drilling with the whole rock
assays from the other programmes shows no
difference in grade tenor. Visual comparison of
grades in the 1993 drillholes with neighbouring
holes from the other programme likewise shows
no notable difference in grade tenor. As such,
despite the description of assaying of coarse
fractions only, the assays from the 1993 drilling
are treated the same as whole rock assays with
no tonnage. Correction required.

Discrepancies in C values in the 1993 samples,
with non-carbonate C occasionally being greater
than the Total C value, are assumed to reflect a
lack of complete homogenization in the
crushing/sieving process carried out on site.

Sample preparation on the 12 vertical 2011
drillholes and the 40 sampled angled 2014
drillholes was undertaken by ALS Adelaide.
Samples were crushed and split to >70% passing
-6mm and pulverized to >85% passing 75μm
prior to assaying by ALS Brisbane.

Sample sizes are deemed appropriate for the
material beingsampled.

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.

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.

Nature of quality control procedures
adopted (eg standards, blanks, duplicates,
external laboratory checks) and whether
acceptable levels of accuracy (ie lack of bias)
and precision have been established.
Techniques used are:

C-IR18 (Graphitic carbon by LECO analyser)

C-CAL15 (Inorganic carbon by difference)

C-IR17 (Organic carbon by LECO analyser)

C-CON01 (Carbon concentrate by LECO analyser)

C-IR07 Total Carbon by LECO analyser)

C-IR18 was used for the 2014 samples, and C-
IR17 was used for previous samples. As the
rocks are assumed to contain no organic material
(supported
by
petrographic
study),
the
difference between these two techniques is less
than the analytical error of the techniques and
hence considered negligible.

Bulk reject duplicate samples were taken in the
42
angled
drillholes
to
ensure
sample
representivity. These duplicates were inserted
at a typical frequency of 1 in 100 samples (1%
rate of insertion). Certified reference standards
were inserted at a typical rate of 1 in 20 samples
(5% rate of insertion) for accuracy checks of
analyses reported by the mineral testing
laboratory ALS Global.

There is no record of field duplicate samples or
standards having been submitted in the 30
vertical
drillholes
to
test
sampling
representatively.

Internal laboratory QAQC for all sampling has
been reviewed with no problems highlighted
with respect to samplingbias orprecision.
KL
Verification of
sampling and
assaying

The verification of significant intersections by
either independent or alternative company
personnel.

The use of twinned holes.

Documentation of primary data, data entry
procedures, data verification, data storage
(physical and electronic) protocols.

Discuss any adjustment to assay data.

There are no twinned drillholes. Areas of
overlap between angled and vertical drillholes
show intercepts of similar tenor and thickness

Assays in the database have been checked
against laboratory certificates and original logs
which contained assay data. No inconsistencies
were identified.

Non-sampled intervals were assumed to be
“unmineralised” and given a Graphitic C value of
0.01%, equivalent to half the detection limit of C-
IR18.
KL
Location of
data points

Accuracy and quality of surveys used to
locate drillholes (collar and down-hole
surveys), trenches, mine workings and other
locations used in Mineral Resource
estimation.

Specification of the grid system used.

Quality and adequacy of topographic control.

Drill location co-ordinates are reported in Uley
Mine Grid (transformed to truncated AMG) The
reported truncation was:
Easting = -554,216.866M
Northing = -6,139,092.867M
ADH = RL +404.252M

Drillhole collars have been re-surveyed in the
field and these transformations validated. All
drillholes were re-surveyed during 2014 by PA
Dansie & Associates Pty Ltd.

A whole of site survey was undertaken during
2014 byMaptek PtyLtd.

Data spacing
and
distribution

Data spacing for reporting of Exploration
Results.

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.

Whether sample compositing has been
applied.

No exploration results are reported or included
in this Mineral Resource estimate.

Diamond drilling on an infill spacing of up to 25m
X 25m was used to estimate geological and grade
continuity at a level deemed appropriate for the
classification and reporting of a Mineral
Resource estimate.

1m sample composites applied during the
estimation process.
KL
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.

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.

Drilling orientation is considered appropriate
considering the deposit type and orientation of
moderately
WNW
dipping
mineralisation.
Sampling bias relating to the orientation of
sampling is considered minimal.

KL
Sample
security

The measures taken to ensure sample
security.

All reasonable measures are being taken to
ensure sample security along the value chain.
These measures include the recording of sample
dispatch and receipt reports, secure storage of
samples, and a locked and gated core shed

The assay method used is destructive. A
representative sample library is maintained on
site.
KL
Audits or
reviews

The results of any audits or reviews of
sampling techniques and data.

No formal third party audits have been
undertaken.

Laboratory
procedures
and
manuals
are
comprehensively documented on-site and both
the AMDEL and ALS laboratories are considered
to be reputable laboratories for carbon analysis.
As the assaying techniques used are broadly
destructive techniques, with a limited ash
residue, they are not suited for replicate
analysis.

The quality control protocols implemented at
Uley are considered to represent good industry
practice and allow some assessment of analytical
precision and accuracy. The assay data is
considered to display acceptable precision.

Internal laboratory QAQC data (standards, blanks
and duplicates) have been reviewed and no
significant problems were identified regarding
thequalityof the assaying.

Mineral tenement
and land tenure
status

Type, reference name/number, location
and ownership including agreements or
material issues with third parties such as
joint ventures, partnerships, overriding
royalties, native title interests, historical
sites, wilderness or national park and
environmental settings.

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 Uley Graphite Project consists of five
contiguous tenements on the Eyre
Peninsula of South Australia, of which two
are retention leases two are mining leases
and one is an exploration licence.
Tenement identification numbers are:
ML5561, ML5562, EL4778, RL66 and RL67.

Mining development is subject to the
approved Program for Environmental
Protection and Rehabilitation (PEPR) and
an Environmental Licence which is
mandated under South Australian State
legislation.

Valence Industries has a 100% interest in
these tenements and no royalty, joint
venture or other material agreements are
in place other than a royalty of 1.5% with
its former parent company SER.

Tenement ownership is secure with
expiration dates varying from 2016
(EL4778) to March 2017 (ML5561 and
ML5562). There are no known
impediments to obtaining a license to
operate in the area.

KL
Exploration done
by other parties

Acknowledgment and appraisal of
exploration by other parties.

A number of parties have undertaken
exploration on the leases and the data set
held by Valence Industries includes all
available information.
KL
Geology
Deposit type, geological setting and style
of mineralisation.

Graphite is developed as a constituent
mineral in coarse prograde metamorphic
assemblages as well as in the fabric and
foliation of micaceaous schists. These are
interpreted to be the folded, thrust and
metamorphosed equivalents of the Cook
Gap Schist. Folding of stratigraphy on
various local scales is obvious.
KL
Drillhole
Information

A summary of all information material to
the understanding of the exploration
results including a tabulation of the
following information for all Material

collar
 elevation or RL (Reduced Level –
elevation above sea level in metres)
of the drillhole collar
 dip and azimuth of the hole
 down hole length and interception
depth
 hole length

If the exclusion of this information is
justified on the basis that the
information is not Material and this
exclusion does not detract from the
understanding of the report, the
Competent Person should clearly explain
why this is the case.

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.

Where aggregate 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.

The assumptions used for any reporting
of metal equivalent values should be
clearly stated.

This table accompanies a Resource
Estimation, and is not reporting
Exploration results.

No metal equivalents are used.
KL
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 drillhole 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’).

As this table accompanies a Resource
Estimation, and is not reporting
Exploration results, this section is not
applicable.

The relationships are captured and
defined on a hole-by-hole basis in the
resource model and orientations of holes
to mineralised zone are appropriately
accounted for in the estimate.
KL
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 plan view
of drillhole collar locations and
appropriate sectional views.

Collar Plan of Resource Drillholes is
presented in Figure 2 of this report.

Typical cross sections are presented in
Figure 5 to Figure 9 of this report.
EM/KL
Balanced
reporting

Where comprehensive reporting of all
Exploration Results is not practicable,
representative reporting of both low and
high grades and/or widths should be
practiced to avoid misleading reporting
of Exploration Results.

Valence Industries carry out balanced
reporting of exploration results.

Selective sampling of only visibly graphitic
material has been carried out on the 2011
and 2014 drill core.
EM/KL
Other substantive
exploration data

Other exploration data, if meaningful
and material, should be reported
including (but not limited to): geological
observations; geophysical survey results;
geochemical survey results; bulk samples
– size and method of treatment;
metallurgical test results; bulk density,
groundwater, geotechnical and rock
characteristics; potential deleterious or
contaminating substances.

All material available exploration
information was considered. This
comprised a drilling database, previous
estimates and reports and academic
literature, petrological reports,
metallurgical test work reports, density
determinations, and site visit
photography/communication. Historical
production records from the original Uley
Mine provided assumptions relating to
futurepotential economic extraction.
KL
Further work
The nature and scale of planned further
work (eg 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 commercially
sensitive.

Exploration work to quantify the extent
and continuity of mineralisation within
the Valence Industries held tenure is
ongoing. This work includes planned
diamond and reverse circulation drilling,
further geophysical surveys and
geological mapping. This exploration
effort is deemed commercially sensitive.

Data validation
procedures used.

Data has been provided as an Access database.

A total of 18 diamond holes drilled 1993 era drilled by Graphite
Mines of Australia, 12 SER diamond drillholes drilled in 2011, and
40 Valence Industries angled diamond holes in the Uley area
have been used in the resource modelling study. The database
used for resource estimation consists solely of diamond drilling
and has been reviewed and re-validated for obvious errors by
Coffey prior to commencing the resource estimation study. The
assay data has been cross checked against assay certificates
provided by ALS Chemex.

The following checks were completed prior to uploading the
drilling data into a Vulcan database:

Check and correct overlapping intervals.

Ensure downhole surveys existed at a 0m depth.

Ensure consistency of depths between different data
tables, for example survey, collar and assays.

Check gaps in the assay data which were replaced by -999.

Hole MD623 had not been assayed at time of data handover and
so has not been included in the resource database.

Hole MD617M is a metallurgical hole and has not been assayed
so has not been included in the resource database.

No records were apparently kept for the sieved fraction weights
from the 1993 drilling to determine factors for tonnage and
assay grade fractions. As discussed in the subsampling section
of Section 1 of this table, statistical comparison of these samples
with the other samples shows there is no difference between the
1993 assays and the whole rock assays. As such the1993
samples are treated as whole rock assays for the Mineral
Resource estimate.

The factors affecting

The current geological interpretation is based on review of
previous estimates and reports and has been augmented by the
geological and structural information provided by the 2014
angled infill diamond drillholes.

Information from site visits and geological reports suggests the
graphite lenses occurs within an anticlinorium i.e. a fold with
parasitic folds on its limbs, as occurred in the Uley mine to the
north. The current model is of a recumbent antiform plunging
very shallowly to the ENE, with HW lodes dipping shallowly to
the WNW and FW lodes dipping moderately (~33°) to the WNW.

Graphitic C (%) was estimated using Ordinary Kriging (OK)
utilising the cut 1m composites in Vulcan mining software.
Grade estimation was constrained to blocks inside the
mineralisation wireframes with hard boundaries applied. The
exception to this was zone 2. This zone contains both a HW and
a FW limb. The blocks were flagged as being HW (202) or FW
(201) but were informed using all composites from zone 2 (both
201 and 202) to allow the estimation of the hinge area to be
well informed. Any non-sampled intervals were assigned a
value of 0.01% Graphitic C.
No other elements were estimated, be they deleterious or not.
No assumptions were made concerning mining selectivity
beyond small to medium scale open pit mining.
Material types and quality were not defined in the model given
the data available for interpretation and estimation. It is
assumed that metallurgical testing based on bulk samples are
broadly representative of products likely to be obtained from
mining of this mineralisation.
The deposit was domained into the following domains:

Footwall domain – in the footwall of the fold, dipping at
approximately 33°

Hanging wall domain – in the hanging wall of the fold,
dipping at approximately 15°

Flat lying domain – shallow overprinting mineralisation
Extreme grade values were top cut. A top cut of 50% Graphitic
C was used within the FW and HW domains and a top cut of 30%
Graphitic C was used within the Flat lying domain. The values
used were determined based on statistical analysis of the
composites within each domain.
The parent block size is approximately ½ of the nominal 25m x
25m drill spacing with sub-blocking chosen to allow for
adequate volume resolution.
The search parameters are suitable given the parent block size,

and

mineralisation.
The Resource estimate was compared with the previous
estimates. The understanding of the orientation and continuity
of the mineralised zones within the current resource, being
based on 25m x 25m spaced drillholes, more than half of which
are angled and contain valid structural data, is of much higher
confidence than in the previous model.
The current model omits a low grade domain incorporated in
the previous model.
The estimate was validated by visual and statistical comparison
of the block estimate grades with the informing 1m composite
grades.

The Uley project has been historically mined by open cut mining
methods and it was assumed that this would still be the case for
any future mining operation.

No assumptions have been made about mining selectivity for
specific material types or quality.

No dilution or other factors have been applied to the resource
estimate.

Conceptually, consideration of the resource estimate and
subsequent mining scenarios remain at a high level only. It is
assumed that there is some basis for determining reasonable
prospects for eventual economic extraction considering historic
mining of the nearby Uley graphite deposit in a very similar
geological setting and location.

of the mining and

Mining development is subject to the development, submission
and approval of a Program for Environmental Protection and
Rehabilitation (PEPR) and an Environmental Licence which is
mandated under South Australian State legislation. The site has
been on care and maintenance since historical production
ended in 1993. It is not expected that environmental constraints
will be considered a material constraint to the prospects of

The bulk density for bulk
material must have
been measured by
methods that
adequately account for
void spaces (vugs,
porosity, etc), moisture
and differences
between rock and
alteration zones within
the deposit.

Discuss assumptions for
bulk density estimates
used in the evaluation
process of the different
materials.

A total of 371 bulk density measurements were collected from
the 2014 drillcore. The Archimedes method was used on uncut
core from 22 representative holes with each distinct lithology
and weathering zone in each hole tested. The bulk density
results were flagged against the ore zones and oxidation state in
Vulcan and averages for mineralised and waste determined for
oxide, transitional and fresh weathered (defined by BOCO and
TOFR surfaces). Four samples were removed prior to running
averages due to being extreme values. Three samples were <1.2
and one was >4. The values were evaluated against core photos
and against “typical” bulk density values as listed in section 9.2
of the Field Geologist’s Manual (Fourth Edition, 2001).

These bulk density values are lower than those used in last
year’s model. It should be noted that the quantity of bulk
density data has improved substantially, and revised and

change is likely to be related to a higher level of weathering of
the host rock than was previously understood.

No corrections have been applied for the sieved fraction weights
from the 18 1993 drillholes to determine factors for tonnage
and assay grade fractions. As discussed in the sampling
sections, these results are statistically no different to the whole
rock assays and as such, these samples are being treated as
whole rock samples for the Mineral Resource estimate.
Classification
The basis for the
classification of the
Mineral Resources into
varying confidence
categories.

Whether appropriate
account has been taken
of all relevant factors (ie
relative confidence in
tonnage/grade
estimations, reliability of
input data, confidence
in continuity of geology
and metal values,
quality, quantity and
distribution of the data).

Whether the result
appropriately reflects
the Competent Person’s
view of the deposit.

Resource classification is based on quantity/quality of sample
data as follows:

The infilling to 25m x 25m drilling centres has increased
sample density to the point where confidence in the
geological and grade continuity, and the quality of the
estimation, are such that the majority of the estimated
blocks are classified as Indicated.

Mineralised zones based on 1 drillhole only remain
unclassified.

Small portions of the mineralisation in the centre of the
fold (zones 1, 2 and 3) have been classified as Measured
due to the continuity of grade thickness and tenor, and the
quality of the estimation. These areas are limited due in
part to uncertainty introduced by selective sampling of the
drillholes.

The classification scheme as applied is considered to adequately
reflect the sample density and geological interpretation.

The resource classification and estimate does not specifically
address the definition or quantity of material types or product
quality as all contacts are relatively gradational and
metallurgical testwork is on-going.

Resource estimates.

Ms Karen Lloyd of Jorvik Resources Pty Ltd (engaged as General
Manager – Technical delivery for Valence Industries) formally

third party reviews have been undertaken on the Mineral
Resources estimation process, though formal peer review
through the Coffey system has been undertaken prior to
reporting.

Discussion of relative
accuracy/ confidence

Where appropriate a
statement of the
relative accuracy and
confidence level in the
Mineral Resource
estimate using an
approach or procedure
deemed appropriate by
the Competent Person.
For example, the
application of statistical
or geostatistical
procedures to quantify
the relative accuracy of
the resource within
stated confidence limits,
or, if such an approach
is not deemed
appropriate, a
qualitative discussion of
the factors that could
affect the relative
accuracy and confidence
of the estimate.

The statement should
specify whether it
relates to global or local
estimates, and, if local,
state the relevant
tonnages, which should
be relevant to technical
and economic
evaluation.
Documentation should
include assumptions
made and the
procedures used.

These statements of
relative accuracy and
confidence of the
estimate should be
compared with
production data, where
available.

The grade estimate is based on the assumption that open cut
mining methods will be applied and high confidence grade
control, for example RC grade control drilling, or ditch-witch
bench top sampling will be available for ore/waste demarcation.
As such the Resource estimate should be considered to be a
global estimate.

The resource classification and estimate does not specifically
address the definition or quantity of material types or product
quality as all contacts are relatively gradational and
metallurgical testwork is on-going. Bulk metallurgical tests are
assumed to be representative of the mineralised material within
the Uley Pit 2 deposit.
