Tomingley Gold Project – Caloma Two Resource Upgrade brings Tomingley close to 1 million ounce gold resource

  • Caloma Two resource estimate increases gold inventory at Tomingley by 13.5%

  • The initial resource at Caloma Two is 1.7 million tonnes grading 2.0g/t gold for 109,300 ounces

  • Total resources within Tomingley Gold Project now 14.29 million tonnes grading 2.0g/t gold for 921,000 ounces

  • The development program remains on schedule and budget to commence production in February

TOMINGLEY GOLD PROJECT (TGP) – gold

Tomingley Gold Operations Pty Ltd (TGO) 100%

The TGP is based on three gold deposits (Wyoming One, Wyoming Three and Caloma) located 14 kilometres north of the Company’s Peak Hill Gold Mine, and approximately 50 kilometres south west of Dubbo (Figure 1). The Caloma Two deposit is located immediately to the south of Caloma and has been subject to extensive resource definition drilling in the last twelve months.

The Project received state development approval in July 2012 and Mining Lease granted in February 2013. Construction of the treatment plant and associated mine facilities are 85% complete with production due to commence on schedule in February 2014.

Mineral Resources

A major drilling program consisting of 22,782 metres of RC drilling in 159 holes and 2,145 metres in 11 diamond core (DD) holes was completed at Caloma Two in late March 2013. The program was designed to confirm mineralisation outlined in broadly spaced drilling completed in 2010 and 2011 and to upgrade to resource status.

The geology, alteration and mineralisation at Caloma Two are very similar to those of the other Tomingley deposits . Economic mineralisation is associated with quartz veining, sulphide accumulation and alteration focused within sub-volcanic porphyritic feldspar porphyry sills and adjacent volcaniclastic sediments. The Wyoming and Caloma deposits appear to have formed as the result of a rheological competency contrast between the porphyritic sub-volcanic sills and the surrounding volcaniclastic sediments, with the sills showing brittle fracture and the sediments ductile deformation. The deposits have many similarities to well documented orogenic-style gold deposits.

Stratigraphy at Caloma Two has a distinctive ESE-WNW orientation, in difference to a dominantly NS trend at the adjacent Caloma deposit. This orientation change is interpreted to result from the interaction of the major NW-SE trending fault that occurs immediately to the south of the deposit. The feldspar porphyry host is thought to form the core of a synformal structure bounded by thin sediment units. (Figure 2).

Like Caloma, mineralisation at Caloma Two is relatively complex. The orientation of the mineralised zones has been determined from the vein direction data obtained from oriented diamond drill core. Mineralisation lies dominantly within the feldspar porphyry where there are both flat (<20°) and moderately north dipping (40°-50°) zones (Figure 3). Other less well defined zones of mineralisation are interpreted to occur near the keel of the synform and interpreted as a reverse saddle and a discontinuous zone of mineralisation developed along the northern sediment horizon which is thought to form a link with the southern mineralised zones at Caloma.

Narrow steeply-dipping tholeiitic dolerite dykes, of slightly differing ages, crosscut the whole sequence and postdate mineralisation. The dykes usually have low gold grades except locally along their margins.

Mr Richard Lewis of Lewis Mineral Resource Consulting Pty Ltd (LMRC), who completed all of the previous resource estimates for the TGP, has compiled an initial resource assessment for Caloma Two. This assessment incorporates all past and current RC and DD drilling completed at Caloma Two (195 RC holes totalling 28,260m and 17 DD holes totalling 3,631m), and is based on interpretation of the mineralised zones completed by Alkane personnel (Figure 4).

The estimates were made using sub-blocks, a primary block size of 2.5m x 2.5m x 5m in X, Y, Z with grade interpolation by Ordinary Kriging. The final resource model is a regularized sub-block model that incorporates some dilution. The resources were limited by an optimum pit design (Figure 5) to ensure that there are reasonable prospects for eventual economic extraction. Further details of the methodology are included in the attached JORC Table (Appendix 1).

The resource at Caloma Two, as constrained by an optimum pit and at a cut-off grade of 0.75g/t gold, is 1.7 million tonnes grading 2.00 g/t gold for 109,300 ounces increasing the total resource inventory at Tomingley to 14.29 million tonnes grading 2.0g/t gold for 921,000 ounces .

Mineralisation that has been modelled but lies outside of the resource will be assessed by the Tomingley operations team for the potential extraction by underground mining methods (Figure 5).

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 1 m samples from which 3 kg was
pulverised to produce a 30 g charge for fire assay’). In other cases more explanation
may be required, such as where there is coarse gold that has inherent sampling
problems. Unusual commodities or mineralisation types (eg submarine nodules) may
warrant disclosure of detailed information.
The Caloma Two deposit has been evaluated using air core, reverse circulation and
diamond drilling techniques. Air core drilling samples were not used in the resource
calculation
Reverse Circulation (RC) samples are collected at one metre intervals via a cyclone and
riffle or cone splitter. Intervals outside of visual ore zones are composited to 3 metres.
Diamond Drill (DD). sample intervals defined by geologist during logging to honour
geological boundaries.
RC drilling completed to industry standards
Core is laid out in suitably labelled core trays. A core marker (core block) is placed at the
end of each drilled run (nominally 3 or 6m) and labelled with the hole number, down hole
depth, length of drill run. Core is aligned and measured by tape, comparing back to this
down hole depth consistent with industry standards.
RC Drilling - approximately 10% (3kg) of total sample is delivered via cone or riffle splitter
into a calico bag with the remaining sample delivered into a large plastic bag and retained
for future use if required.
DD Drilling – sample intervals defined by geologist during logging to honour geological
boundaries.
All samples sent to laboratory are crushed and or pulverised to produce a ~100g pulp for
assay process.
All samples are fire assayed using 50g charge.
Visible gold is occasionally observed in both core and RC samples
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).
The resource is based on 195 RC drill holes totalling 28,260 metres and 17 diamond core
drill (DD) holes totalling 3,631 metres.
Conventional RC drilling using 100mm rods and 144mm face sampling hammer.
DD holes are pre-collared with un-oriented triple tube PQ3 (83mm diameter) core drilling
through to competent material averaging 70 metres depth and cased down to triple tube
HQ3 (61mm diameter) core tails. HQ3 core is oriented using the “Ace” core orientation
tool.
Drill sample
recovery

Method of recording and assessing core and chip sample recoveries and results
assessed.
RC - sample recovery is visually estimated and generally very good (>90%) aided by the
use of oversized shrouds through oxide material. Samples are even sized. Samples are
rarely damp or wet. Sample quality is assessed by the sampler by visual approximation of
sample recovery and if the sample is dry, damp or wet. Riffle and cone splitters were used
to ensure a representative sample was achieved on all 1 metre samples.
DD - core loss is identified by drillers and calculated by geologists when logging. Generally
≥95% was recovered and any loss is usually in portions of the oxide zone. Triple tube large
diameter PQ3 core is used through the oxide material to ensure the greatest recovery.

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.
RC drilling completed using oversized shrouds to maintain sample return in oxide zone and
all samples are split using riffle or cone splitters. Use of RC rigs with high air capacity
assists in keeping samples dry.
Triple tube coring is used at all times to maximise core recovery with larger diameter PQ3
core used in the oxide and saprolite zones.
There is no known relationship between sample recovery and grade.
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.
RC - each one metre interval is geologically logged for characteristics such as lithology,
weathering, alteration (type, character and intensity), veining (type, character and intensity)
and mineralisation (type, character and volume percentage).
DD - all core is laid out in core trays and geologically logged for characteristics such as
lithology, weathering, alteration (type, character and intensity), veining (type, character and
intensity) and mineralisation (type, character and volume percentage). A brief geotechnical
log is also undertaken collecting parameters such as core recovery, RQD, fracture count,
and fracture type and orientation.
All logging is qualitative with visual estimates of the various characteristics.
RC - A representative sample of each one metre interval is retained in chip trays for future
reference.
DD - Core is photographed and all unsampled core is retained for reference purposes.
All DD core and RC chip samples have been geologically and geotechnically logged by
qualified geologists.
Sub-sampling
techniques
and sample
preparation

If core, whether cut or sawn and whether quarter, half or all core taken.
DD - zones of visual mineralisation and/or alteration are marked up by the geologist and
cut in half using an Almonté (or equivalent) core cutting saw. The right half is sampled to
sampling intervals that are generally based on geology but do not exceed 1.2 metres in
length. The left half is archived. All mineralised zones are sampled, plus >2m of visibly
barren wall rock.
Laboratory Preparation – drill core is oven dried prior to crushing to <6mm using a jaw
crusher, split to 3kg if required then pulverised in an LM5 (or equivalent) to ≥85% passing
75µm. Bulk rejects for all samples are discarded. A pulp packet (±100g) is stored for future
reference.

If non-core, whether riffled, tube sampled, rotary split, etc and whether sampled wet or
dry.
RC - for each one metre interval with visual mineralisation and/or alteration the calico
sample bag is numbered and submitted to the laboratory for analysis. Intervals without
visual mineralisation and/or alteration are spear sampled and composited over three
metres. Rare damp or wet samples are recorded by the sampler. For composited intervals
returning grades >0.2g/t Au the calico bags are retrieved for assay of the individual
intervals.
Laboratory Preparation – the entire RC sample (3kg) is dried and pulverised in an LM5 (or
equivalent) to ≥85% passing 75µm. Bulk rejects for all samples are discarded. A pulp
packet (±100g) is stored for future reference.

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.
Alkane (ALK) sampling techniques are of industry standard and considered adequate.
RC – field duplicate samples collected at every stage of sampling to control procedures
DD – external laboratory duplicates used.
RC - Duplicate samples are riffle split from the riffle/conical split calico from the drill rig.
Duplicates show generally excellent repeatability, indicating a negligible “nugget” effect.
Sample sizes are industry standard and considered appropriate.
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. _
Gold is determined using a 50g charge fused at approximately 1100°C with alkaline fluxes,
including lead oxide. The resultant prill is dissolved in aqua regia and gold determined by
flame AAS.
For other geochemical elements samples are digested in aqua regia with each element
concentration determined by ICP Atomic Emission Spectrometry or ICP Mass
Spectrometry. These additional elements are generally only used for geological
interpretation purposes, are not of economic significance and are not routinely reported.
Not applicable to this report or deposit.
Commercially prepared Certified Reference Materials (CRM) are inserted at 1 in 50
samples. CRM’s are not identifiable to the laboratory.
Field duplicate samples are inserted at 1 in 50 samples (alternate to CRM’s).
Laboratory QAQC sampling includes insertion of CRM samples, internal duplicates and
screen tests. This data is reported for each sample submission.
Failed standards result in re-assaying of portions of the affected sample batches.
2% of samples were submitted for external laboratory checks establishing a deemed
satisfactory level of accuracy and precision.
Screen fire assaying (75µm mesh) was undertaken on 1.5% of samples deeming a
negligible “nugget” effect. Screen fire assay data overrides all other methods.
Verification of
sampling and
assaying

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

The use of twinned holes.
Drill data is compiled and collated, and reviewed by senior staff. External consultants do
not routinely verify exploration data until resource estimation procedures are deemed
necessary.
Twinned holes have not been used at Caloma Two as twinning provides verification only
for extremely limited areas of a deposit.

Documentation of primary data, data entry procedures, data verification, data storage
(physical and electronic) protocols.
All drill hole logging and sampling data is hard keyed into Excel spreadsheet for transfer
and storage in an access database with verification protocols in place.
All primary assay data is received from the laboratory as electronic data files which are
imported into sampling database with verification procedures in place. QAQC analysis is
undertaken for each laboratory report.

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.
Drill holes are laid out using hand held GPS (accuracy ± 2m) then surveyed accurately (±
0.1m) by licenced surveyors on completion.
RC drill holes are surveyed using a single shot electronic camera at a nominal 30m down
hole interval.
DD are surveyed at nominal 30m down hole during drilling to maintain drilling direction and
then at 6m intervals on retrieval of rod string using a multi shot electronic camera.
AMG66 grid was used.
The area is very flat. A site based digital terrain model was developed from accurate (±
0.1m) survey control by licenced surveyors.
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.
Nominal drill hole spacing is 20m x 20m.
The data spacing is the same as used at defining the Caloma resource and was
established to be sufficient.
The drillhole spacing has been shown to be appropriate by variography.
Sample compositing is not applied until resource estimation stage.
RC – samples with no visible mineralisation or alteration are composited to 3m with 1m
resamples assayed if the composite returned a gold value of >0.2g/t gold. One metres
samples override 3m composites in the database.
DD – core is sampled to geology.
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.
Much care is given to attempt to intersect structure at an optimal angle but in complex ore
bodies this can be difficult.
It is not thought that drilling direction will bias assay data at Caloma Two.
Sample
security

The measures taken to ensure sample security.
All samples are bagged in tied numbered calico bags, grouped into larger tied polyweave
bags and transported 30 minutes away to Parkes. The samples are placed in large sample
cages with a sample submission sheet and couriered to ALS in Orange via freight truck. All
sample submissions are documented via ALS tracking system and all assays are reported
via email.
Samplepulps are returned to site and stored for an appropriate length of time(minimum 3

Deposit type, geological setting and style of mineralisation.
Geological nature of the Tomingley Deposits is well documented elsewhere.
Mineralisation is associated with quartz veining and alteration focused within sub-volcanic
basaltic-andesite sills and adjacent volcaniclastic sediments. The deposits appear to have
formed as the result of a rheological contrast between the porphyritic sub-volcanic sills and
the surrounding volcaniclastic sediments, with the sills showing brittle fracture and the
sediments ductile deformation, and have many similarities to well documented lode-style
gold deposits.

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.
Exploration results previously reported –
for uncut gold grades;
Intercepts are defined (bounded) by 0.5g/t gold outer limit and may contain some
internal waste;
Only intervals grading ≥1 g/t gold are reported;
Grades are calculated by length weighted average.
Exploration results previously reported as length weighted average grades with internal
high grade intercepts reported separately.
No metal equivalents are reported.
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 (eg ‘down hole length, true width not known’).
Previously reported exploration results include an estimate of true width. The
mineralisation is structurally complex and true widths are variable depending on the ore
zone intersected however range between 60% and 80% of drill intersection.
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.
Cross sections and a plan showing geology with drill collars were included with previously
reported exploration results.
Various plans and sections illustrating the modelled ore zones with all drill traces are
attached.
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.
Data relating to all drill holes has been reported in previous documentation of exploration
results.

Estimation
and modelling
techniques

The nature and appropriateness of the estimation technique(s) applied and key

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.

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 (eg sulphur for acid mine drainage characterisation).
13 mineralisation wireframes (domains) and 5 dolerite wireframes were interpreted and
used as constraints for the resource modelling. Four surfaces were also used to separate
material types - topography, alluvium, saprolite and base of oxidation surfaces.
The drill hole data were flagged by dolerite and mineralised domain wireframes in priority
order, to prevent double use the data in the intersecting zones. The samples immediately
outside the mineralised zones were re-flagged, if they contained more than 0.25 g/t gold, in
order to prevent any overestimation that could be caused by use of assay boundaries. This
re-flagging is also useful for the RC samples that are not broken at barren dyke boundaries.
The samples were composited to 1m, the most common sample length and flagged by the
topography, alluvium, saprolite and base of oxidation surfaces.
The top-cut declustered data had Coefficient of Variation (CV’s) of less than 1.7 for the
mineralised zones, allowing use of Ordinary Kriging for estimation.
Average variogram models were fitted for the mineralised zones and dolerite dykes.
Estimates were made by Ordinary Kriging, with check estimates by Inverse Distance
Squared (ID2) and Nearest Neighbour methods.
Datamine Studio 3 V22 was used.
The resources are limited by an indicative pit design to ensure they have reasonable
prospects for eventual economic extraction.
There are no previous estimates or any production data to provide any validation.
No assumptions made - Estimates were made for gold, arsenic and copper; only gold was
of economic significance.
Estimates were made for gold, arsenic and copper; only gold was of economic significance.

In the case of block model interpolation, the block size in relation to the average
sample spacing and the search employed.
The primary block size was small (2.5m x 2.5m x 5m) because of the narrow dipping nature
of the mineralisation zones.
The average drill hole spacing was 20m and variogram ranges 22m x 26m x 3.5m.
The primary search was equal to the variogram ranges; secondary search were made
using 2x and 3x the primary search.

The main part of the Caloma Two deposit is likely to be mined by open pit methods. Some
dilution was added when the estimated sub-block model was regularized; this reduced the

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.
The resources were classified using the search pass; only estimates made within the
defined mineralisation zones in the first search pass were classified as Indicated
Resources. The dimensions of the search pass were based on the variogram ranges.
No Measured Resources were defined, because of some uncertainly in the geological
interpretation of the mineralisation zones, and the use of a high proportion of Reverse
Circulation drilling (RC) for exploration.
The use of RC drilling limits the amount of geological information that can be logged, and
boundaries of mineralisation zones cannot be precisely located.
The classification reflects the Competent Persons view of the deposit and its supporting

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 Caloma Two deposit consists of 13 narrow mineralisation zones; consequently there
are relatively few drillhole data in each zone. This has limited the accuracy of any fitted
variogram model and forced the use of average variogram models. The use of an
approximate variogram model does not greatly affect the accuracy of the kriged grades as
kriging is a very robust estimation process. It does, however, limit the accuracy of the
variance of the estimates and any confidence limits that might be statistically inferred.
No statistical or geostatistical method (non-linear or simulation) was used to quantify the

  • sampling technique - RC and air core samples are collected at one metre intervals and initially composited to 3m for initial assay. All composites returning grades of ≥0.2g/t Au are subsequently riffle split and appropriate sized samples bagged for despatch to the laboratory. NQ, HQ and PQ diamond drill core was halved;

  • sample recovery - RC sample recovery is usually very good (>80%). Samples are usually dry. Core recovery was usually very good;

  • assay technique – samples were submitted to commercial laboratories for preparation by drying, grinding and sub-sampling and then analysed by industry standard Fire Assay techniques. 3m composite RC and air core samples are analysed from a 30g charge whilst the 1m RC and AC resplits and half diamond core from a 50g charge;

estimation techniques - Estimations used a 3D pseudo-wireframe geological model as a basis for inverse distance squared grade extrapolation into a block model. Block size is 2.5m x 2.5m x 5.0m but sub-blocking was used (Wyoming One: 1.25m to 2.5m in X and Y and 0.25m to 5m in Z, Wyoming Three: 0.625m to 2.5m in X and Y and 0.25m to 5m in Z). Wireframes/ore zones are constrained by boundaries defined by geology, structure and a 0.25 g/t Au grade envelope. The estimation search filters were dynamically re-orientated to follow the changing orientations of the wireframes.

Comparative techniques such variable block size, Nearest Neighbour and Kriging, were used to generate additional estimates for validation of the quoted resources.

As sample intervals for Wyoming One ranged from 0.1m to 5.0m, assays were composited to 1m intervals for the modelling. A total of 16,716 samples are within the wireframe.

Sample intervals for Wyoming Three ranged from 0.2m to 4.0m, and these assays were composited to 1m intervals for the modelling. A total of 12,836 samples are within the wire frames;

top cut Top Cuts were selected for the 8 individual mineralized domains (ore zones) within Wyoming One using a combination of cutting plots, histograms and probability plots. Top Cuts ranged from 8g/t Au to 45g/t Au. For Wyoming Three there are 4 mineralized domains and Top Cuts ranged from 17g/t Au to 30g/t Au.
