WHIM CREEK PROJECT RESOURCE UPDATE

Highlights

  • Re-modelling of the Mineral Resource estimate for the Salt Creek and Mons Cupri copper zinc deposits within the Whim Creek Project are now completed.

  • The revise Salt Creek model incorporate infill drilling conducted since the previous resource estimate was calculated and also includes geological, geophysical and structural models aimed at improving the understanding of the geometry of the high-grade sulphide zones.

  • The new models, while considered more sophisticated, has led to little change in the overall contained metal with lower grades at Salt Creek offset by increased tonnages and negligible changes in both the grades and tonnages at Mons Cupri.

  • Salt Creek - 1.8 Mt grading 1% Cu, 4.2% Zn, 1.2% Pb and 31g/t Ag.

  • Revised Resource at Mons Cupri is 5.1Mt grading 0.9% Cu, 1% Zn, 0.4% Pb and 21g/t Ag.

Venturex Resources Limited (ASX: VXR) (“Venturex” or “the Company”) is pleased to announce an updated Mineral Resource estimates for the Mons Cupri and Salt Creek copper-zinc deposits which form part of the Company’s 100% owned Whim Creek Copper Zinc Project.

The updated Resources, which were prepared by independent consultant Hardrock Mining Consultants Pty Ltd, are the result of Venturex’s decision to apply new infill drilling results, along with updated geological, geophysical and structural data to the model.

The Company is pleased to advise that despite the application of the more robust data sets, the overall result remains in line with previous estimates.

While the outcome of the revision is pleasing, Venturex‘s key focus remains the Sulphur Springs Project, as discussed in the Resource upgrade released on the 21[st] March 2018.

Implications for Future Exploration

The revised mineral resource estimates for Mons Cupri and Salt Creek incorporate an increased focus on the distribution and geometry of the mineralisation. This provides a robust basis from which to plan future exploration targeted at the discovery of concealed high-grade VMS deposits within the Whim Creek project area.

As previously announced, Venturex was successful in securing a Government cofunded drilling grant to test for VMS mineralisation under cover south west of the Mons Cupri deposit.

Regional Geological Setting

The Whim Creek Copper Zinc Project contains three main deposits, Whim Creek, Salt Creek and Mons Cupri, located within the Archaean Whim Creek Greenstone Belt. The deposits are classed as volcanic massive sulphide (VMS). Both Mons Cupri and Salt Creek are hosted at a similar stratigraphic level within the upper Cistern Formation of the Bookingarra Group. Modern style exploration began in the late 1960’s and drilling has been largely restricted to the deposit environments whereas much of the target stratigraphy is concealed beneath younger volcanic sequences and has not been subjected to systematic evaluation. Therefore the potential for additional discoveries in the district remains high.

Salt Creek Deposit

The updated Salt Creek Resource estimate follows on from work completed by VXR and its consultants. This work included re logging of core from 31 diamond holes, structural modelling of the deposit by Model Earth Global Geological Services, reprocessing and modelling of historical and recent downhole geophysical data by Southern Geoscience Consultants and completion of 6 diamond drill-holes within and around the upper part of the deposit and 3 deep diamond drill-holes down plunge of the previously known resources targeted at geophysical anomalies.

Summary of Key Information

Geology and geological interpretation

Salt Creek is a structurally modified VMS deposit. The deposit does not outcrop and the upper part is weathered to about 50m depth. The deposit has not been previously mined and remains open at depth.

The main massive sulphide lenses dip steeply south and plunge moderately to steeply east. The deposit is structurally overturned from its original position and is strongly elongated down plunge. The sulphide lenses are hosted in the upper parts of fine to medium grained bedded tuffaceous sediment with some massive sulphide lenses transgressing into the overlying shales and mudstones. The tuffaceous sandstone and siltstone show typical VMS zoned alteration of chlorite-pyrite and sericite which extends into the underlying rhyolitic volcanics. The alteration intensity shows a strong increase to the east and down plunge (see Figure 2).

==> picture [455 x 316] intentionally omitted <==

Drilling techniques

The main drilling technique used at Salt Creek is diamond drilling. Core size drilled is mostly NQ with some HQ. RC drilling with a 5.5-inch face sampling hammer has also been used.

Sampling and analysis methods

Diamond core was cut with a diamond saw and half core sample sent for laboratory analysis. Analysis was undertaken with a four acid digest with ICP/MS finish and 30g FA/AAS for precious metals.

==> picture [155 x 52] intentionally omitted <==

Estimation Methodology

A polygonal interpretation of stratiform copper and zinc-lead domains was undertaken on 12.5 metre sections which were then balanced in plan view at 25m level intervals. The copper wireframe used a ~0.25% cut-off, the zinc-lead wireframe uses a ~1% Zn cut-off. The estimation employed inverse distance techniques using SURPAC 6.8 software.

Other relevant information

The key changes between the updated Salt Creek Resource and the previous estimate are an increase in the Resource tonnage of ~850kt. The increased tonnage has resulted in the absolute Cu, Zn and Pb grades decreasing by 1%, 2.8% and 0.9% respectively, compared to the previous estimate. As a result contained Cu metal has decreased by ~1.5kt while contained Zn and Pb metal has increased by ~7.7kt and ~1.2kt respectively.

The changes are a result of increased geological understanding, which has been gained through the drilling completed over the course of 2016, structural re-interpretation and re-logging of a number of pre-existing drill holes.

The improved geological understanding provides for better definition of mineralised domains compared to the previous estimate. The improved interpretation has resulted in a greater volume of mineralisation being included within the Resource estimate and the definition of a number of sub domains which allows for the identification and modelling of this mineralisation (see Appendix 1 for detailed breakdown of domains).

Mons Cupri Deposit

The updated Mons Cupri resource estimation was completed by independent consultant, Hardrock Mining Solutions. It follows on from work by VXR to better define the geometry and distribution of the high grade sulphide zones as part of a broader strategy to explore down plunge to the west beneath younger volcanic and sedimentary sequences. The oxide portion of the Mons Cupri deposit and the adjacent North West Mons Cupri area was mined most recently as an open pit, 2005-2009, with copper production via an SX/EW process. The current sulphide resource is located adjacent to and down plunge west of the main open pit and adjacent to the North-west pit area (Figure 3).

Summary of Key Information

Geology and Geological interpretation

The Mons Cupri deposit is hosted towards the upper part of the Cistern Formation and approximately 20m below the overlying Rushall Shale. The main resource broadly comprises a gently west dipping and tapering semi massive sulphide zone, 300m x 160m x 5-20m thick, overlying a steeply dipping conical shaped stringer sulphide zone, 350m x 150m x `30m thick. The global resource was divided into seven domains based on the mineralisation styles and metal ratios (See Table 4 within the Appendix).

  • Zinc Domain: The Zinc domain is located at the top of the deposit and is broadly a gently dipping zone of semi massive zinc and lead rich sulphides with a high silver content. (>5% Zn & 1% Pb, <1% Cu).

  • Copper – Zinc domain: This mixed zone is located immediately below the Zinc Domain. It comprises semi massive zinc lead sulphides as above with transgressive copper sulphide veins (>1% Zn & >1% Cu).

  • Copper Stringer Core Domain: This zone immediately below the Zinc Domain and the Copper Zinc Domain is dominated by generally steeply dipping stringer style copper sulphide mineralization with low zinc and lead content (>1% Cu & <0.5%Zn).

  • Copper Stringer Domain: Similar style to the Copper Stringer Core Domain above but is deeper with less chalcopyrite (0.5%-1% Cu, >1% Zn).

  • Zinc - Lead Stringer Domain: This forms the outer shell of the stringer sulphide zone forming a zone around the Copper Stringer Domains (Zn & Pb ~0.5% & Cu >0.2%).

  • Mixed Stringer Domain: Sub vertical shear controlled mixed copper-zinc and lead sulphide zones mostly below the main pit (Zn-Pb-Cu ~0.5%).

  • North West Pit: Separate smaller VMS occurrence to the north west of the main Mons Cupri pit

==> picture [155 x 52] intentionally omitted <==

Drilling techniques

Mons Cupri has been sampled with a combination of Reverse Circulation (RC) and diamond (DD) drill holes. The RC drill holes were sampled via standard cyclone and riffle splitter. Diamond drilling accounts for ~53% of the drilling.

Sampling and analysis methods

Diamond core was cut with a diamond saw and half core sample sent for laboratory analysis. Analysis was undertaken with a four acid digest with ICP/MS finish and 30g FA/AAS for precious metals.

Estimation Methodology

A polygonal interpretation of six domains was carried out on 20-metre sections. The interpretation honours the paragenic sequence. The resource estimate has been undertaken using inverse distance techniques using SURPAC V6.8.1 software.

Other relevant information

The key changes between the updated Mons Cupri Resource and the previous estimate are an increase in the Resource tonnage of ~490kt. The increased tonnage has resulted in the contained Cu metal has increasing by ~3.9kt while contained Zn and Pb metal has decreased by ~7.4kt and ~2.6kt respectively.

The changes between the updated Mons Cupri Resource and the previous estimate are the result of reinterpreting the existing available geological information. In particular a detailed review and assessment of four twinned holes (previously drilled) was undertaken and the modelled domains were aligned to previous mineralisation studies completed by Miller (1975) and then Houston (1996).

The revised geological interpretation and hence level of understanding has allowed for seven key mineralisation domains being defined (see Appendix 1 for detailed breakdown of domains). As discussed above the revised domaining has resulted in a small increase in the volume of mineralised material being included within the Resource estimate.

Reported Whim Creek Reserves and Resources

With the release of the updated Mons Cupri Resource, it is the Company’s view that it is no longer appropriate to report Reserves for the Mons Cupri and Whim Creek deposits. Therefore, the Mons Cupri and Whim Creek Reserves as reported in the Company’s release of 26 October 2017 have been reclassified as Resources. The Company is currently assessing the merits of reviewing and updating the required technical work to reinstate the Reserves.

The Whim Creek Resource is restated below in Appendix 1 due a typographical error having being identified.

APPENDIX 2

MONS CUPRI RESOURCE STATEMENT NOTES 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 (e.g. 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 (e.g. ‘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 (e.g. submarine nodules) may warrant disclosure of detailed information.

The deposit was sampled with a combination of Reverse Circulation (RC) and
diamond (DD) drill holes. The RC drill holes are sampled via standard adjustable
cyclone and riffle splitter from the recovered sample. Diamond drill core is
sampled using standard cut half core.

Standard RC drilling produced whole metre RC drill samples split at the rig using
a cone splitter producing samples of approximately 3kgs. Diamond drilling
completed to industry standard using predominantly NQ size core. Diamond
core was cut on geologically determined intervals (0.25 to1.5 metres).

were weighed, dried, crushed and pulverised (total prep) to produce a pulp
sub-sample for analysis by four acid digests with an ICP/OES, ICP/MS or FA/AAS
(Au) finish.
Drilling
techniques

Drill type (e.g. core, reverse circulation, open-hole hammer, rotary air blast,
auger, Bangka, sonic, etc.) and details (e.g. 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.). _

A combination of percussion (open hole and reverse circulation) and diamond
drilling of various sizes over 47 years used. 53% was by diamond drilling
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.

Diamond drill core recovery was recorded by all operators as a percentage of
measured recovered core versus drilled distance. Recoveries were generally
high.

RC samples were compared to standards to estimate sample recoveries which
were consistently high. Any low recovery intervals were logged and entered
into the database.

The cyclone and splitter were routinely inspected and cleaned during the
drilling ensuring no excessive material build-up. Care was taken to ensure the
split samples were of a consistent volume.
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 and percentage of the relevant intersections logged.

Diamond drill core is all qualitatively logged with wet core photographs taken
over the last 8 years. RC drill holes are all were qualitatively logged and RC chip
tray samples collected and stored.

Logging is at an appropriate detailed quantitative standard to support future
geological, resource, reserve estimations and subsequent feasibility studies.

All holes were logged in full. Relogging was completed on 31 core holes in
2016/17.

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.

Diamond core was sawn with a diamond saw and half core samples (quarter
core in metallurgical holes) taken for assay.

1 metre RC samples were collected and split off the drill rig using a cone splitter.
Approximately 90% of the samples were dry in nature.

The sample preparation of the samples follows industry best practice in sample
preparation involving weighing, oven drying, pulverisation of the entire sample
(total prep) to a grind size of 85% passing 75 microns.

Venturex and previous operators had QAQC procedures involving the use of
certified standards, blanks and duplicates. The QAQC has been independently
audited with no apparent issues.

Field duplicates have been taken.

The sample sizes are considered appropriate given the relatively fine-grained
nature of the sulphide mineralisation which is not nuggetty in nature, the
samplingmethodologyand thepercent assayvalue ranges involved.
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 (e.g. standards, blanks,
duplicates, external laboratory checks) and whether acceptable levels of
accuracy (i.e. lack of bias) and precision have been established.

Various operators used analytical techniques involving a four acid digest multi-
element suite with ICP/MS finish (30g FA/AAS for precious metals). The acids
used are hydrofluoric, nitric, perchloric and hydrochloric acids, suitable for the
dissolution of most silica based samples. The method approaches total
dissolution of most minerals. Combustion furnace or Eltra “Leco” analyser
assayed total sulphur.

No geophysical tools are used to determine any element concentrations
reported.

Duplicates were taken every 25m and post 2008, every RC metre drilled is
checked by two 30sec measurements using a Niton handheld XRF.
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.

Prior to 2010, verification procedures were not documented.

Post 2010, significant intersections were viewed by the Exploration Manager
and Managing Director. Significant intersections are also verified by portable
XRF data collected in the field and cross-checked against the final assays when
received.

A range of primary data collection methods were employed since 1989. Since
2009, data recording used a set of standard Excel templates on a data logger
and uploaded to note book computer. The data is sent to Perth office for
verification and compilation into an SQL database by the in-house database
administrator. Full copies are stored offsite.

Full data base verification of all historical information was completed in 2009. All
data is loaded and stored in DataShed database.

The historical data (pre-2010) has been adjusted with all negative assays,
representing below detection assays, were converted to positive assays of
0.001ppm.
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.

Specification of the grid system used.

Quality and adequacy of topographic control.

All hole collar coordinates have been checked by Venturex using DGPS with all
co-ordinates and RL data considered reliable.

Downhole surveys were performed on all holes by either single shot Eastman
camera or reflex gyro readings at 10-50 metre down hole intervals.

Thegrid system used for the location of all drill holes is MGA_GDA94,Zone 50.

Topographic control is provided by combination of external survey control,
photogrammetryanalysis and DGPS reading.
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.

The nominal drill spacing is generally 20m x 20m varying due to previous
imperial grid pattern and more recent metric grid.

The current spacing is adequate to assume geological and grade continuity of
the mineralised domain.

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.

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.

The Mons Cupri drilling is orientated to the North West, near perpendicular to
the mineralised trend. Limitations imposed by drilling conditions dictates that
some drilling was vertical and orientated at a low angle to the mineralisation..

Given the stratigraphic nature of the mineralising system, no orientation based
samplingbias has been identified in the data.
Sample security
The measures taken to ensure sample security.

Independent audits of the data in 2009 concluded that the sampling protocols
were adequate.

Post 2010, the chain of custody is managed by Venturex. The samples are
stored in a secure facility at Whim Creek, collected from site by Toll IPEC and
delivered to the assay laboratory in Perth. Online tracking is utilised to track the
progress of batches of samples.
Audits or
reviews

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

Independent audits of the sampling techniques and data were completed as
previous and current feasibility studies in 2008 (Straits) and 2011 (Snowden). The
studies were comprehensive and cover all industry standard issues. There does
not appear to be anysignificant risk in acceptingthe data as valid.

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.

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’).

Previous reports highlight down hole intercept 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 plan view of drill hole collar locations and
appropriate sectional views.

See long section in previous ASX Annual Reports (2010, 2011) and ASX releases.
Balanced

Database
integrity

Measures taken to ensure that data has not been corrupted by, for example,
transcription or keying errors, between its initial collection and its use for Mineral
Resource estimation purposes.

Data validationprocedures used.

Independent audits of the sampling techniques and data integrity were
completed as part of previous studies in 2008 (Straits) and 2011 (Snowden). The
studies were comprehensive and cover all industry standard issues. There does
not appear to be anysignificant risk in acceptingthe data as valid.
Site visits
Comment on any site visits undertaken by the Competent Person and the
outcome of those visits.

If no site visits have been undertaken indicate why this is the case.

No site visit was made by the Competent Persons for this Resource Statement.
The site is well documented and previous verification records by others are
available.
Geological
interpretation

Confidence in (or conversely, the uncertainty of) the geological interpretation
of the mineral deposit.

Nature of the data used and of any assumptions made.

The effect, if any, of alternative interpretations on Mineral Resource estimation.

The use of geology in guiding and controlling Mineral Resource estimation.

The factors affecting continuity both of grade and geology.

The interpretation of the deposit takes full account of all surface and
subsurface
geological,
geochemical,
structural
and
previous
mining
information contained in the database to ensure the continuity and integrity of
the interpretation.

No detailed alternative interpretations have been postulated.

Recent detailed structural mapping and previous scientific studies are the basis
of the controls on mineralisation and mineralisation styles. In the main zone at
least three phases of mineralisation are recognised as strata bound zinc lead
silver mineralisation, massive replacement copper and iron sulphides and
disseminated iron and copper stringer zones. These styles control grade and
distribution of minerals and result in six mineral domains.

In the North-West Zone onlystringer style mineralisation is recognised.
Dimensions
The extent and variability of the Mineral Resource expressed as length (along
strike or otherwise), plan width, and depth below surface to the upper and
lower limits of the Mineral Resource.

The Mineral Resource covers the strata bound, massive sulphide and underlying
stringer mineralisation identified by drilling. The Main Mons Cupri zone measures
~300 metres (NW) by 160 metres (NE). It is approximately 5-20 metres thick and
dips to the west at 30 degrees. Its stringer zone measures 350metres (EW), 150
metres(down dip)and isgenerally30 metres thick.
Estimation and
modeling
techniques

The nature and appropriateness of the estimation technique(s) applied and key
assumptions, including treatment of extreme grade values, domaining,
interpolation parameters and maximum distance of extrapolation from data
points. If a computer assisted estimation method was chosen include a
description of computer software and parameters used.

The availability of check estimates, previous estimates and/or mine production
records and whether the Mineral Resource estimate takes appropriate account
of such data.

The assumptions made regarding recovery of by-products.

Estimation of deleterious elements or other non-grade variables of economic
significance (e.g. sulphur for acid mine drainage characterisation).

In the case of block model interpolation, the block size in relation to the
average sample spacing and the search employed.

The Mons Cupri Mineral Resource Estimate takes into account previous
estimates completed by Straits Resource inverse distance techniques using
SURPAC V6.8.1 software.

Polygonal interpretation of six domains was done on 20-metre sections. The
interpretation honoured the paragenic sequence which is Strat bound zinc
lead mineralisation (Greater than 5% zinc and 1% lead with less than 1% copper,
mixed copper zinc replacement domain with more than 1% copper but zinc
between 1 and 5%, copper replacement with coper more than 15 but zinc less
than 1%, weaker replacement copper domain with copper less than 15 but
more than 0.5% , contact zinc rich stingers in stock work and stock work stringer

boundaries are used between domains.

Parent cell measures 5 metres (X axis), 5 metres (Y) and 3 metres (Z) with sub-
cells of 2.5 metres (X), 2.5 metres (Y), 1.5 metres (Z), appropriate given an
average drill spacing of less than 25 metres. Depending on search ellipse the
minimum samples per estimate are between 2 and 5 and the maximum
samples per estimate are 9 to 20. Discretisation was set to 5(Y) X 5(X) X 3(Z).

Top cuts were applied to the informing data set assays at a 98 percentile value
if the coefficient of variation exceeded 1.5 for each domain.

Composite length was set at 1.5 metre. The estimate also considered the
distribution of deleterious elements sulphur, antimony, arsenic, bismuth,
cadmium,cobalt,iron etc.)
Moisture
Whether the tonnages are estimated on a dry basis or with natural moisture,
and the method of determination of the moisture content.

Tonnages are estimated on a dry basis. Moisture content in ore is insignificant.
Cut-off
parameters

The basis of the adopted cut-off grade(s) or quality parameters applied.

Wireframes used a 0.8% Cu cut-off and 2% Zn cut-off for high-grade domains.
Low-grade domains used a 0.2% Cu cut-off. Cut off grades were determined
geostatistically.

The Mineral Resource estimate is reported at 0.4% Cu or 2% Zn, this being an
economic cut-off for a standalone openpit operation.
Mining factors
or assumptions

Assumptions made regarding possible mining methods, minimum mining
dimensions and internal (or, if applicable, external) mining dilution. It is always
necessary as part of the process of determining reasonable prospects for
eventual economic extraction to consider potential mining methods, but the
assumptions made regarding mining methods and parameters when estimating
Mineral Resources may not always be rigorous. Where this is the case, this
should be reported with an explanation of the basis of the mining assumptions
made.

No assumption made. Previous oxide area mined successfully by open cut
methods which may be applicable to the resource reported.
Metallurgical
factors or
assumptions

The basis for assumptions or predictions regarding metallurgical amenability. It is
always necessary as part of the process of determining reasonable prospects
for eventual economic extraction to consider potential metallurgical methods,
but the assumptions regarding metallurgical treatment processes and
parameters made when reporting Mineral Resources may not always be
rigorous. Where this is the case, this should be reported with an explanation of
the basis of the metallurgical assumptions made.

Metallurgical .test demonstrate normal flotation method applicable to
recovering principal economic minerals i.e. chalcopyrite and sphalerite.
Environmental
factors or
assumptions

Assumptions made regarding possible waste and process residue disposal
options. It is always necessary as part of the process of determining reasonable
prospects for eventual economic extraction to consider the potential
environmental impacts of the mining and processing operation. While at this
stage the determination of potential environmental impacts, particularly for a
greenfield project, may not always be well advanced, the status of early
consideration of these potential environmental impacts should be reported.
Where these aspects have not been considered this should be reported with an
explanation of the environmental assumptions made.

Estimate include sulphur and rock type lithologies which allow estimation of
potential waste and process residue disposal options and environmental
impact considerations.

Bulk density
Whether assumed or determined. If assumed, the basis for the assumptions. If
determined, the method used, whether wet or dry, the frequency of the
measurements, the nature, size and representativeness of the samples.

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.

Density have been determined from actual measurements conducted on site
by the classical water immersion method, using the total core for each sample.

Assigned average specific gravity values were used in the resource estimation:
2.5 g/cm3for oxide waste, 2.74 g/cm3for fresh waste, 2.86 g/cm3for the
stringer zone, 2.97 g/cm3for the copper rich domains and 3.14 g/cm3for the
zinc rich domains.
Classification
The basis for the classification of the Mineral Resources into varying confidence
categories.

Whether appropriate account has been taken of all relevant factors (i.e.
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.

Mineral Resource classification into Inferred, Indicated and Measured
categories is based on a combination of average weighted distance from
sample points, sample density and geological interpretation confidence.
Audits or
reviews

The results of any audits or reviews of Mineral Resource estimates.

No third party review has been carried out on this estimate.
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 resource estimate is considered robust in light of similar results obtained by
different parties and estimation methods.

The resource report is a global assessment of the Mons Cupri deposit.

No production data for the sulphide mineralisation is available. Previous mining
of the oxide copper mineralisation was conducted by Straits Resources in 2007-
2009. The reconciliation information is not considered applicable to resource
estimate given the different nature of the material mined.

SALT CREEK RESOURCE STATEMENT NOTES 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 (e.g. 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 (e.g. ‘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 (e.g. submarine nodules) may warrant disclosure of detailed information.

The deposit is sampled with a combination of Reverse Circulation (RC) and
diamond (DD) drill holes completed on 15-40 metre spacing across the deposit
to a maximum vertical depth of depth of 475 metres. The RC drill holes were
sampled via standard adjustable cyclone and riffle splitter from the recovered
sample. Diamond drill core is sampled using standard cut half core.

Standard RC drilling since 2005 produced whole metre RC drill samples split at
the rig using a cone splitter producing samples of approximately 3kgs. Previous
diamond drilling completed to industry standard using predominantly NQ size
core. Diamond core was orientated, aligned and cut on geologically
determined intervals (0.1 to 4metres).

Samples were weighed, dried, crushed and pulverised (total prep) to produce
a pulp sub-sample for analysis by four acid digest with an ICP/OES, ICP/MS or
FA/AAS (Au) finish.
Drilling
techniques

Drill type (e.g. core, reverse circulation, open-hole hammer, rotary air blast,
auger, Bangka, sonic, etc.) and details (e.g. 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 (67%)is the main technique using mostly NQ size with some HQ
sizes using a variety of rig types Drill core was generally orientated. RC drilling
with a 5.5-inch face sampling hammer was used after 2005.
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.

Diamond drill core recovery was recorded by all operators as a percentage of
measured recovered core versus drilled distance. Recoveries were generally
high and bear no relationship with grades.

2010 RC samples had estimated sample recoveries which were consistently
high. Any low recovery intervals were logged and entered into the database.
There is no relationship of grade to recovery.

The cyclone and splitter are routinely inspected and cleaned during the drilling
ensuring no excessive material build-up. Care is taken to ensure the split
samples were of a consistent volume.
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 and percentage of the relevant intersections logged.

Diamond drill core is all qualitatively logged with wet core photographs taken
over the last 8 years. RC drill holes are all were qualitatively logged and RC chip
tray samples collected and stored.

Logging is at an appropriate detailed quantitative standard to support future
geological, resource, reserve estimations and subsequent feasibility studies.

All holes are logged in full.

Relogging of previous diamond drill holes to gain additional structural data was
carried out in 2016 and 2017

core in metallurgical holes) taken for assay.

1 metre RC samples are collected and split off the drill rig using a cone splitter.
Approximately 90% of the samples were dry in nature.

The sample preparation of the samples follows industry best practice in sample
preparation involving weighing, oven drying, pulverisation of the entire sample
(total prep) to a grind size of 85% passing 75 microns.

Samples with QAQC data were evaluated using QAQCR assay quality reporting
software. QAQC data evaluation included field duplicates, lab standards,
repeats and lab blank flushes. The QAQC has been independently audited with
no apparent issues.

Field duplicates have been taken since 2005 but only105 are in mineralised
areas. The results show no issues with sampling quality.

The sample sizes are considered appropriate given the relatively fine grained
nature of the sulphide mineralisation which is not nuggetty in nature, the
samplingmethodologyand thepercent assayvalue ranges involved.
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 (e.g. standards, blanks,
duplicates, external laboratory checks) and whether acceptable levels of
accuracy (i.e. lack of bias) and precision have been established.

Various operators used analytical techniques involving a four acid digest multi-
element suite with ICP/MS finish (30g FA/AAS for precious metals). The acids
used are hydrofluoric, nitric, perchloric and hydrochloric acids, suitable for the
dissolution of most silica based samples. The method approaches total
dissolution of most minerals. Combustion furnace assayed total sulphur.

No geophysical tools are used to determine any element concentrations
reported.

Duplicates were taken every 25m and post 2010, every RC metre drilled is
checked by two 30sec measurements using a Niton handheld XRF.

An independent analysis of intra laboratory bias and precision was undertaken.
No discernible bias was noted for samples used.
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.

Prior to 2010, verification procedures were not documented.

Post 2010, significant intersections were viewed by the Exploration Manager
and Managing Director. Significant intersections are also verified by portable
XRF data collected in the field and cross-checked against the final assays when
received.

A range of primary data collection methods were employed since 1968. Since
2010, data recording used a set of standard Excel templates on a data logger
and uploaded to note book computer. The data is sent to Perth office for
verification and compilation into an SQL database by the in-house database
administrator. Full copies are stored offsite.

Full data base verification of all historical information was completed in 2009.
DataShed™ was used for drill hole and sample data storage and validation.

The historical data (pre-2010) has been adjusted with all negative assays,
representing below detection assays, were converted to positive assays of half
the negative value.
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.

Specification of thegrid system used.

All hole collar coordinates have been checked by Venturex using DGPS with all
co-ordinates and RL data considered reliable.

Downhole surveys were performed on all holes by either, acid etch, tropari
single shot Eastman camera or reflexgyro readings at 30 metres down hole

intervals.

The grid system used for the location of all drill holes is MGA_GDA94, Zone 50.

The resource estimate is based on a local grid system which used transformed
coordinates for data.

Topographic control is provided by combination of external survey control,
photogrammetryanalysis and DGPS reading.
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.

The nominal drill spacing is generally 30m x 40m.

The current spacing is adequate to assume geological and grade continuity of
the mineralised domain.

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.

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.

The Salt Creek drilling is orientated predominantly to the northwest, near
perpendicular to the mineralised trend. Given the stratigraphic nature of the
mineralising system, no orientation based sampling bias has been identified in
the data.
Sample security
The measures taken to ensure sample security.

Independent audits of the data in 2010 concluded that the sampling protocols
were adequate.

Post 2009, the chain of custody was managed by Venturex. The samples are
stored in a secure facility at Whim Creek, collected from site by Toll IPEC and
delivered to the assay laboratory in Perth. Online tracking is utilised to track the
progress of batches of samples.
Audits or
reviews

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

Independent audits of the sampling techniques and data were completed in
2008 (Straits) and 2011 (Snowden). The studies were comprehensive and cover
all industry standard issues. There does not appear to be any significant risk in
acceptingthe data as valid.

a clear statement to this effect (e.g. ‘down hole length, true width not known’).

Previous reports highlight down hole intercept 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 plan view of drill hole collar locations and
appropriate sectional views.

See long section in previous ASX Annual Reports (2010, 2011) and previous ASX
releases.
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.

All results are reported.
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.

NA - Exploration results not being released this time.
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 commercially sensitive.

Section 3 Estimation and Reporting of Mineral Resources

(Criteria listed in section 1, and where relevant in section 2 apply to this section.)

Criteria JORC Code Explanation Commentary
Database
integrity

Measures taken to ensure that data has not been corrupted by, for example,
transcription or keying errors, between its initial collection and its use for Mineral
Resource estimation purposes.

Data validation procedures used.

Independent audits of the sampling techniques and data integrity were
completed as part of previous and current feasibility studies in 2008 (Straits) and
2011 (Snowden). The studies were comprehensive and cover all industry
standard issues. There does not appear to be any significant risk in accepting
the data as valid.
Site visits
Comment on any site visits undertaken by the Competent Person and the
outcome of those visits.

If no site visits have been undertaken indicate why this is the case.

No site visit under taken as the site is substantially rehabilitated and outcrop is
minimal. Previous competent person has visited site.
Geological
interpretation

Confidence in (or conversely, the uncertainty of) the geological interpretation
of the mineral deposit.

Nature of the data used and of any assumptions made.

The effect, if any, of alternative interpretations on Mineral Resource estimation.

The use of geology in guiding and controlling Mineral Resource estimation.

The factors affecting continuity both of grade and geology.

The interpretation of the deposit takes account of all surface and subsurface
geological, geochemical, and structural information contained in the
database to ensure the continuity and integrity of the interpretation.

No detailed alternative interpretation(s) have been presented.

The stratiform nature and structural aspects of the mineralisation provides a
good level of geological control in the interpretation.

Stringer mineralisation is broadlyconstrained by geologyand assayboundaries.
Dimensions
The extent and variability of the Mineral Resource expressed as length (along
strike or otherwise), plan width, and depth below surface to the upper and
lower limits of the Mineral Resource.

The Mineral Resource covers two separate mineralised zones identified by
drilling over a distance of 700m east west, 150m north south and about 450m
vertically. The zinc lead silver mineralisation is remobilised into a structural setting
parallel to the local stretching lineation at approximately local grid direction
plunge of -47 towards 101 degrees and forms zone from less than 1m to 10m
true thickness. The copper mineralisation is more strata bound and has both
massive and stringer type zones associated with extensivepyrite.
Estimation and
modelling
techniques

The nature and appropriateness of the estimation technique(s) applied and key
assumptions, including treatment of extreme grade values, domaining,
interpolation parameters and maximum distance of extrapolation from data
points. If a computer assisted estimation method was chosen include a
description of computer software and parameters used.

The availability of check estimates, previous estimates and/or mine production
records and whether the Mineral Resource estimate takes appropriate account
of such data.

The assumptions made regarding recovery of by-products.

Estimation of deleterious elements or other non-grade variables of economic
significance (e.g. sulphur for acid mine drainage characterisation).

In the case of block model interpolation, the block size in relation to the
average sample spacing and the search employed.

Any assumptions behind modelling of selective mining units.

Any assumptions about correlation between variables.

The Salt Creek Mineral Resource Estimate considers previous estimates
completed by Straits Resources (2006, 2008) and Venturex (2010).

The estimation employed inverse distance techniques using SURPAC 6.8
software.

Polygonal interpretation of stratiform copper and zinc-lead domains was done
on 12.5 metre sections which were then balanced in plan view at 25m level
intervals. The copper wireframe used a ~0.25% cut-off, the zinc-lead wireframe
uses a ~1% Zn cut-off.

Gaps between higher-grade domains were modelled as low grade or sulphide
domains to be later incorporated as planned dilution during the mining process.
Hard boundaries are used for the domains.

Search ellipse parameters determined using down hole variography. Parent cell
measures 12.5 metres (X axis), 5 metres (Y) and 10 metres (Z) with sub-cells of
3.125 metres (X), 1.25 metres (Y), 2.5 metres (Z), appropriate given an average
drill spacingof 30 metres. Minimum samplesper estimate is 5,maximum

Description of how the geological interpretation was used to control the
resource estimates.

Discussion of basis for using or not using grade cutting or capping.

The process of validation, the checking process used, the comparison of model
data to drill hole data, and use of reconciliation data if available.
samples per estimate is 10. Discretisation was set to 3(Y) X 3(X) X 3(Z).

No grades were cut.

Composite length was set at 1 metre (79% of samples were this length). Both the
copper and zinc domains were validated visually in 12.5 metre slices.

The estimate also considered the distribution of deleterious elements such as
sulphur,antimony,arsenic,bismuth,cadmium,iron
Moisture
Whether the tonnages are estimated on a dry basis or with natural moisture,
and the method of determination of the moisture content.

Tonnages are estimated on a dry basis. Moisture content of the rocks is
insignificant.
Cut-off
parameters

The basis of the adopted cut-off grade(s) or quality parameters applied.

Cut off grades were determined statistically.
Mining factors
or assumptions

Assumptions made regarding possible mining methods, minimum mining
dimensions and internal (or, if applicable, external) mining dilution. It is always
necessary as part of the process of determining reasonable prospects for
eventual economic extraction to consider potential mining methods, but the
assumptions made regarding mining methods and parameters when estimating
Mineral Resources may not always be rigorous. Where this is the case, this
should be reported with an explanation of the basis of the mining assumptions
made.

The mineralisation depth and shape probably prevent open pit mining and
would require underground mining.
Metallurgical
factors or
assumptions

The basis for assumptions or predictions regarding metallurgical amenability. It is
always necessary as part of the process of determining reasonable prospects
for eventual economic extraction to consider potential metallurgical methods,
but the assumptions regarding metallurgical treatment processes and
parameters made when reporting Mineral Resources may not always be
rigorous. Where this is the case, this should be reported with an explanation of
the basis of the metallurgical assumptions made.

Flotation method of recovery producing separate copper, zinc and lead
concentrates has been demonstrated in preliminary sighter metallurgical test
work. It is assumed the resource reported will be amenable to this processing
route.
Environmental
factors or
assumptions

Assumptions made regarding possible waste and process residue disposal
options. It is always necessary as part of the process of determining reasonable
prospects for eventual economic extraction to consider the potential
environmental impacts of the mining and processing operation. While at this
stage the determination of potential environmental impacts, particularly for a
greenfield project, may not always be well advanced, the status of early
consideration of these potential environmental impacts should be reported.
Where these aspects have not been considered this should be reported with an
explanation of the environmental assumptions made.

Surface disturbance is expected to be minimal given the flat grass dominated
terrain.

All boxcut and underground waste rock can be returned underground as stope
fill.

Processing of the ore is expected to occur offsite with tailings to be stored in a
conventional surface tailings facility adjacent to the nominated treatment
plant.

Water management will be via dedicated evaporation ponds.
Bulk density
Whether assumed or determined. If assumed, the basis for the assumptions. If
determined, the method used, whether wet or dry, the frequency of the
measurements, the nature, size and representativeness of the samples.

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 evaluationprocess of

A high proportion of the assayed samples have bulk density measurements
determined by the water immersion technique on drill core.

Assigned average specific gravity (SG) values were used in the resource
estimation: 2.51 g/cm3for oxide, 2.75 g/cm3for fresh waste, 3.07 g/cm3or 4.13
g/cm3for copper lenses, 2.83 or 3.75 g/cm3for the high grade zinc/lead lenses.

the different materials.
Classification
The basis for the classification of the Mineral Resources into varying confidence
categories.

Whether appropriate account has been taken of all relevant factors (i.e.
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.

Mineral Resource classification into Inferred and Indicated categories is based
on a combination of average weighted distance from sample points, sample
density and geological interpretation confidence.
Audits or
reviews

The results of any audits or reviews of Mineral Resource estimates.

No review of the resource estimate has been carried out.
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 resource estimate is considered +/- 20% given the structural complexity
and given similar results obtained by other parties and estimation methods.

The resource report is a global assessment of the Salt Creek deposit.

No production data is available.
