ASX Release

PENNY’S FIND GOLD DEPOSIT NEW RESOURCE ESTIMATION AMENDED

470,000 tonnes @ 4.42g/t Au for 66,800oz

An inventory of nearly 67,000 ounces of gold at robust grades has been announced by Empire Resources Ltd (‘Empire’, ASX code: ERL) under a new up dated 2012 JORC compliant resource estimation for the Company’s Penny’s Find gold deposit, 50 kilometres northeast of Kalgoorlie in Western Australia. (Refer Figure 2)

The new reportable mineral resource of 470,000 tonnes @ 4.42g/t Au (Table 1) is reported at cut-offs of 0.5g/t Au and 1.5g/t Au to reflect those parts of the total resource which have the potential to be economically viable for extraction by open cut and underground mining methods.

The reportable open cut resource has been estimated to a depth of 100m – see criteria in Appendix 1.

The total in situ mineral resource extends to at least 250m below surface and remains open at depth (Figure 1).

Table 1

The higher average grade for the new resource is due mainly to a more tightly constrained wireframe model which more accurately reflects the outline of highergrade component of the mineralisation.

The new resource estimation was calculated by DataGeo Geological Consultants (‘DataGeo’) and incorporates results from recent metallurgical drilling announced to the ASX on the 21 July 2015. The data, interpretation and techniques utilised in the estimate of the mineral resource are summarised in Appendix 1.

In addition, DataGeo has compiled resource reporting criteria, risks and comments covering geology and mineralisation interpretation, drill information and sampling, sample preparation and analysis, estimation methodology, validation and classification, reporting and mining and metallurgy that were utilised in the resultant mineral resource estimate. This information has been presented as an excerpt from DataGeo’s report called Empire Resources Ltd Penny’s Find Deposit Mineral Resource Update August 2015 in Appendix 2

An excerpt on Mineral Resource History from the same Datageo report is reproduced in Appendix 3.

Empire Resources Ltd holds 60% equity in the Penny’s Find gold deposit with Brimstone Resources Ltd holding the remaining 40% equity in the project.

High grade, coarse gold mineralization at Penny’s Find is hosted by quartz veins at the contact between shale and basalt. (Refer Figure 3)

Preliminary metallurgical test work has shown both oxide and fresh mineralization to be free milling with a high gravity recoverable gold component of >60% and a total gold recovery of >96%.

The Penny’s Find gold deposit is situated on granted Mining Lease 27/156.

APPENDIX 1 JORC Code 2012 - Table 1

Section 1 : Sampling Techniques and Data

Section 1 : Sampling Techniques and Data Section 1 : Sampling Techniques and Data Section 1 : Sampling Techniques and Data
Criteria Explanation Comments
Sampling
techniques
• Nature and quality of sampling (eg cut
channels, random chips, or specific specialised
industry standard measurement tools
appropriate to the minerals under
investigation, such as down hole gamma
sondes, or handheld XRF instruments, etc).
These examples should not be taken as limiting
the broad meaning of sampling.
The deposit has been drilled and sampled by
diamond coring, reverse circulation and rotary
air blast methods with holes on variable
spacings over a 500m strike length, the closest
being a 20mE x 10m N grid. The total metres of
the 109 RC and diamond holes used in mineral
resource estimation is 11,754m. The holes are
drilled mostly to the west to intersect the
relatively steeply east dipping north‐south
orientated mineralisation.
• Include reference to measures taken to
ensure sample representivity and the
appropriate calibration of any measurement
tools or systems used.
Initial RAB and shallow RC drilling targeted the
areas of old workings and identified near
surface mineralisation. This was supplemented
by deeper drilling to highlight the mineralisation
within the Shear zone. The RC samples are
collected from the cyclone of the rig with some
split to smaller samples using a rotary or cone
splitter attached to the cyclone or spear
sampled from the large sample. Sample
representivity was governed by sample recovery
which can be erratic in wet conditions.
Diamond core was collected into core trays with
acceptable recovery.
• 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 diamond core was HQ sized near surface
and NQ sized in the mineralised zones. Core was
halved and 1/2 sent for sample preparation by
crushing, pulverising and splitting to produce
either a 30gm or 40gm charged size dependent
on the Laboratory. RC drilling collected samples
at 1m intervals down hole. These 1m samples
were either composited to 4m intervals by
spear sampling or submitted as 1m samples
each of approximately 2.5 to 4Kg. These
samples were dried, crushed and pulverised and
either a 30gm, 40gm ort 50gm sub‐sample
(dependent on laboratory) selected for FA
assay.
Drilling
techniques
• Drill type (eg core, reverse circulation,
open‐hole hammer, rotary air blast, auger,
Bangka, sonic, etc) and details (eg core
diameter, triple or standard tube, depth of
diamond tails, face‐sampling bit or other type,
whether core is oriented and if so, by what
method, etc).
Diamond drilling (4 surface collared holes and 2
tails to RC holes) is mostly NQ sized through the
mineralised zone, the surface holes totalled
1,259m and the two tails 198m. The core was
not orientated. The RC holes were all 135mm
diameter and drilled with a face sampling bit,
the total number of holes is 105 and total
metres is 10,296.
Drill sample
recovery
• Method of recording and assessing core and
chip sample recoveries and results assessed.
The core recovery recorded is length recovered
per run, the recovery is in excess of 95%. The RC
sample recovery is recorded descriptively as
good, medium or poor and that work by
weighing samples indicated that good recovery
was in excess of 75% and poor recovery was
usually less than 25%, this occurred mostly in
wetground.
• Measures taken to maximise sample
recovery and ensure representative nature of
the samples.
For RC drilling the collar was sealed and air
pressure was used to maximise return. The
cyclone was cleaned between 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.
No assessment has been made of grade v RC
sample recovery but based on the descriptive
assessment the majority of mineralisation was
returned dry and thus usually with good
recovery. The competency of the core
demonstrates that there should be minimal
potential for sampling bias.
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.
Core and chips have been geologically logged
recording lithology, mineralisation, veining,
alteration, weathering and some geotechnical
features (core only) like RQD. The geological
logging is appropriate to the style of the
Deposit.
• Whether logging is qualitative or
quantitative in nature. Core (or costean,
channel, etc) photography
geological logging is both in summary
(comments) and detailed by interval for the
information listed above.
• The total length and percentage of the
relevant intersections logged.
the entire length of all diamond and RC holes,
apart from surface casing, has been logged.
Sub‐sampling
techniques and
sample
preparation
• If core, whether cut or sawn and whether
quarter, half or all core taken.
all core to be sampled was 1/2ed using a
mechanical saw. It is not known if the core was
consistently taken from one side of the stick.
• If non‐core, whether riffled, tube sampled,
rotary split, etc and whether sampled wet or
dry.
RC samples are collected from the cyclone into
a plastic bucket and then transferred to a
sample bag. In addition a smaller sample is split
using a rotary or cone splitter attached to the
cyclone. The cyclone was cleaned with air and
any loose material scrapped off between
samples. Sub‐samples of the larger samples are
taken with a spear.
• For all sample types, the nature, quality and
appropriateness of the sample preparation
technique.
All samples (approx. 2.5 to 4Kg for the RC
samples and 1/2 NQ core up to 1m long) are
provided to a commercial accredited laboratory
facility for the preparation of samples using
industry standard practises of drying, crushing
andpulverisingto allow sub‐samplingbyriffle
or rotary splitter to a 30 to 50gm charge size.
• Quality control procedures adopted for all
sub‐sampling stages to maximise
representivity of samples.
Empire did not include Standards or Blanks for
the 2007 drill program with their routine
samples submitted to the Laboratory but used
an Umpire Laboratory and SFA v FA
comparisons to provide control on quality.
Brimstone included Standards and Blanks at
rates of approximately 1 QAQC sample to 12
Routine samples or better. Whilst there was
some evidence of bias of the lower grade
Standard (1.3g/t) the majority of results can be
considered acceptable. Empire included
Standards and Blanks in their 2015 drilling
campaign at a similar rate to Brimstone.
• Measures taken to ensure that the sampling
is representative of the in situ material
collected, including for instance results for field
duplicate/second‐half sampling.
Duplicate RC sampling was conducted in 2012
and the results were supportive of the original
results. No 1/2nd half core duplicate assay
results have been observed.
• Whether sample sizes are appropriate to
the grain size of the material being sampled.
Whilst there is coarse gold in the system the
outlier grades returned are not excessive as
such the sampling appears to be representative
and thus the global grade is being fairly
represented.
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.
The assay techniques applied for the
measurement of gold content is appropriate for
the determination of the level of gold in the
sample. Comparison between SFA and FA
methods are reasonable this indicating that the
analytical methods adopted report total gold
content.
• 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.
none applied
• 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.
Standards and Blanks were included at
approximately 1 in 12 and 1 in 10 of the number
of samples submitted for the recent (2012 and
2015) holes. The results were mixed with the
lower grade Standards showing a potential high
grade bias (2012 program). Umpire laboratory
checking provided support for the original
results.
Verification of
sampling and
assaying
• The verification of significant intersections
by either independent or alternative company
personnel.
mineralisation intercepts have been determined
by previous and current company personnel and
appear correct
• The use of twinned holes. No specific twinning program has been
conducted.
• Documentation of primary data, data entry
procedures, data verification, data storage
(physical and electronic) protocols
primary data was recorded directly onto
electronic spread sheets and validated against
expected codes. Assay information in electronic
form from the laboratories was merged with
sample interval data on sample number
• Discuss any adjustment to assay data. non applied
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.
The collar positions were surveyed by
contractors after the completion of the 2012
drilling using an RTKGPS on the GDA 94 Zone 51
Datum and the AHD. This survey included some
of the 2007 drill collars which confirmed the
location of these holes in the 2007 data set. The
orientation and dip at the start of the hole was
recorded for all holes. Down hole information
was recorded by single shot camera that
measured dip only for most RC holes with the
exception of later part of the 2007 RC program
where azimuth was also measured. The
diamond tails were measured for dip and
azimuth using a gyroscopic inclinometer. The
2015 drill hole collars were not surveyed post
drilling and no down orientation was
undertaken due to the holes relatively short
length!
• Specification of the grid system used. The regional grid is GDA94 Zone 51 and the
Deposit is laid out on a local grid for a central
control point with a 40orotation.
• Quality and adequacy of topographic
control.
Topographic control is taken from contouring
the drill hole collar information and applying
observations of the site to assist in control.
Data spacing and
distribution
• Data spacing for reporting of Exploration
Results.
Drill spacing varies with position in the deposit
from 10mN x 20mE to in excess of 50m.
• 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.
Successive drilling programs have in filled and
extended (at depth) the previous drilling and on
the majority of occasions drilling has returned
mineralisation in the expected locations. This
provides a high degree of confidence in the
geological continuity. Close spaced drilling
provides good support for positioning of the
mineralisation by zone.
• Whether sample compositing has been
applied.
The sampling reflects the geological conditions.
For mineral resource estimation a 1m
composite length was chosen given that this is
the dominant sample length.
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.
The drilling is oriented as best as possible to
perpendicular to the structure/geology
containing or controlling the mineralisation.
• If the relationship between the drilling
orientation and the orientation of key
mineralised structures is considered to have
introduced a sampling bias, this should be
assessed and reported if material.
No sampling bias is considered to have been
introduced.
Sample security • The measures taken to ensure sample
security.
The chain of custody adopted by operators of
the project appears appropriate and is based on
responsibility and documentation.
Audits or reviews • The results of any audits or reviews of
sampling techniques and data.
A brief audit of assay records revealed no data
errors.

Criteria Explanation Comments
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.

There is no data storage system in place. Data
from logging, sample submission and the assay
laboratory is combined in many spreadsheets.
Previously (2014) key holes utilised in the
mineral resource assessment had their sample
submission and assay laboratory data re‐
entered and compared to the data within the
supplied spreadsheet and no errors were
found. Similarly the data from the 2015 was
reviewed and found to reflect the field and
laboratory data. There has been no exhaustive
review just sufficient to give confidence that
the data to be utilised is accurate with respect
to the supportinginformation.
• Data validation procedures
used.
Data is validated when combined from the
various sources described above. The "audits"
described above provided sufficient confidence
in the data contents to state that it most likely
accurately represents the drill information.
Site visits • Comment on any site visits
undertaken by the Competent
Person and the outcome of those
visits.
DataGeo visited the site on March 26th 2014
and was able to establish that the drill holes
were correctly positioned, the old workings
and position of the shear was appropriate; the
topography was generally flat with fall to the
east and a rise existed at the southern central
end of the area. Also RC chips, chip trays and
diamond core was reviewed to establish the
support for the mineralisation. No site visit to
inspect the recent drilling program was felt
necessary
• If no site visits have been
undertaken indicate why this is the
case.
not applicable
Geological
interpretation
• Confidence in (or
conversely, the uncertainty of) the
geological interpretation of the
mineral deposit.
The confidence in the geological interpretation
is considered good as it is supported by surface
mapping and corroboration of the surface
positions with the close spaced drilling. The
Penny's Find Shear is a major outcropping
feature and the quartz associated gold
mineralisation within it (as modelled) appears
consistent with the feature.
• Nature of the data used and of
any assumptions made.
Only physical data obtained in the field was
utilised.
• The effect, if any, of alternative
interpretations on Mineral
Resource estimation.
The application of hard boundaries to reflect
the position of the zones which host the
mineralisation is supported by the field and
drilling observations. This interpretation is
thought to be appropriate to the style of
mineralisation be it the entire shear (2014) or
just the higher‐grade zones within the shear
(2015).
• The use of geology in guiding
and controlling Mineral Resource
estimation.
The position of the shear provides the overall
geological control with some allowance for
interpreted fault, this combined with presence
of gold is used to constrain the interpretation.
• The factors affecting continuity
both of grade and geology.
The higher‐grade gold zones occur mostly
within the overall Shear appearing to be sub‐
parallel to Shear. To the east of the Shear and
within the weathered profile there is
interpreted to be flat lying supergene style
mineralisation. The position and style of
mineralisation impacts thegrade continuity.
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 main mineralisation within the Deposit
occurs over a 450m strike length and extends
some 250m down dip and varies between 2
and 10m in width. The deposit remains open at
depth although thinning.
Estimation • 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 largest high‐grade zone contained in
excess of 440 composites and provided a
reasonable continuity model which supported
the use of ordinary kriging. The composites
were top‐cut and search restricted. Zones with
fewer composites (insufficient data to perform
a continuity assessment) had grade estimated
using inverse distance to the power of 3 to
reflect the relatively high nugget within the
Deposit. If there were < 10 composites the
grade was assigned as the average of the
composites. In all cases if appropriate
composites were top‐cut. Grade estimation
was carried out in VulcanTMapplication. Density
was assigned based on, for fresh rock,
representative measurements made from what
core was available. For oxidised and partially
oxidised material specific gravity was assigned
based on results from similar deposits within
the general area. 1m composites were created
within each zone and input to the grade
estimation (or assigning) was restricted to
those composites which were within the zone
being assessed. Estimated blocks were
informed in a three step strategy with
orientation set to the orientation of the zone
being estimated. The initial (primary) search
was 30m x 20m x 5m in strike, dip and across
dip‐strike plane. This search range was
expanded bydouble the length for blocks were
not informed in the primary search and again
in the final search strategy. This strategy
informed on average 94% of the blocks within
the zones to be estimated in the primary and
secondary search.
and modelling
techniques
• The availability of check
estimates,
previous
estimates
and/or mine production records
and whether the Mineral Resource
estimate takes appropriate account
of such data.
There is no mining history. The previous model
was significantly larger in tonnes with lower
grade above cut‐off due to the modelling of the
entire shear zone. Check estimates for the
largest zone using inverse distance provided a
similar result.
• The assumptions made
regarding recovery of by-products.
No assumptions made.
• Estimation of deleterious
elements
or
other
non-grade
variables of economic significance
(eg sulphur for acid mine drainage
_characterisation). _
No assessment of deleterious elements has
been made.
• In the case of block model
interpolation, the block size in
relation to the average sample
spacing and the search employed.
The block model was constructed using blocks
which were 5mE x 20mN x 5mRL with sub‐
celling to 2.5mE x 10mN x 1mRL the block size
in each direction adopted to ensure accurate
volume representation of the various surface
and zones. Grade estimation was to the parent
block size.
• Any assumptions behind
modelling of selective mining units.
none undertaken
Estimation • Any assumptions about
correlation between variables.
no assessment undertaken
and modelling
techniques
(continued)
• Description of how the
geological interpretation was used
to control the resource estimates.
Hard boundaries were applied to the Zones.
Grade was estimated within these boundaries.
• Discussion of basis for using or
not using grade cutting or capping.
Statistical analysis indicated that some zones in
particular the largest ones had elevated
coefficients of variation and thus to minimise
the influence of outlier grades top‐cuts were
applied, high‐grade influence was restricted in
some circumstances
• The process of validation,
the checking process used, the
comparison of model data to drill
hole data, and use of reconciliation
data if available.
Volume validation was carried out by
comparison of the solids representing the
mineralisation to the block model. Grade
validation was carried by both global
comparison of the average estimated grade to
the average input grade and spatially by
comparison of the estimated grades to the
input grades by position for the largest zone.
Also visual comparison was used.
Moisture • Whether the tonnages are
estimated on a dry basis or with
natural moisture, and the method
of determination of the moisture
content.
The tonnages were estimated using specific
gravity determined by weight in air
measurements for fresh rock. This data was
then assigned to the appropriate positions in
the block model by rock type. Indicative values
were assigned to the weathered profile.
Cut-off
parameters
• The basis of the adopted cut-off
grade(s) or quality parameters
applied.
The margin of the zones of mineralisation is a
combination of lithology and grade. Given the
model targeted higher grade anomalous gold is
considered to be the 0.5g/t and above. For
mineral resource reporting cut‐off of 0.5g/t for
open cut (to depth of 100m) and 1.5g/t for
underground (beneath 100m) returns that part
of the resource which, based on grade alone,
has thepotential to be mined.
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.



Mining scoping studies based on previous
models indicated that economic extraction by
open cut could occur to 80m below the
surface. The details of this assessment are not
known to DataGeo but it is assumed that the
then mineral resource was optimised using
indicative cost structures (2007 to 2009 and
2015) and gold prices. Such studies did not
review the potential for underground mining.
Post these studies underground mining
scenarios have been considered.
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.

Some metallurgical test work to determine
gold recovery (both by gravity and cyanide
leaching) has occurred which indicates that the
recovery would be in excess of 95%. This was
based on two very high‐grade samples (one of
oxide, the other of fresh) which are not
representative of the likely open cut mining
grade that this deposit could support.
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
greenfields
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.

The Deposit is located on a granted mining
license. DataGeo is unaware of any studies
relating to environmental impacts of a
potential mining and processing operation in
the location. These are numerous mining and
processing operations within 50Km of the site
thus it is considered likely that environmental
impacts would be manageable.
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.
Density has been assumed based on a limited
number of core sample measurements using
weight in the air and weight in water
technique. The results were applied to the
appropriate locations in the model.
Assumptions were made as the density of the
material in the weathered profile.
• 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
alterationzoneswithin the deposit.
The rocks do not display significant porosity
thus the technique adopted is appropriate.
• Discuss assumptions for bulk
density estimates used in the
evaluation process of the different
materials.
The material is generally fairly uniform as
evidenced by the consistency in what specific
gravity information is available.
Classification • The basis for the
classification of the Mineral
Resources into varying confidence
categories.
The classification is based on the quality and
amount of input data; the spatial arrangement
of the drill data and its supported position; the
grade continuity for the largest zone and
confidence in the geological interpretation
which is supported by field observation and
drilling. Whilst QAQC information is lacking for
the 2007 drilling comprehensive programs for
the 2012 and 2015 drilling was mostly
supportive. Higher confidence areas have more
supporting data, areas of lower geological
support reflect a lower classification.
• 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).
The input data particularly the more recent is
consistent and closely spaced enough to
support the projection of the geological
interpretation at depth which in terms of style
of mineralisation is consistent with other
deposits within the same or similar geological
setting. Later drilling programs have
successfully in filled earlier programs in
mineralised locations predicted by the initial
programs ‐ this is particularly the case with the
2015 drilling. The estimated grade correlates
reasonably well with the input data given the
nature of the mineralisation.
• Whether the result appropriately
reflects the Competent Person’s
view of the deposit.
The Mineral Resource estimate reflects the
Competent Persons understanding of the
Deposit.
Audits or
reviews.

reviews of Mineral Resource
estimates.

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

expected there is sensitivity to the estimated
resource grade related to be the top‐cut
applied with indication that grade could be
influenced by 10 to 15% in the main
mineralised zone. Whilst DataGeo is
comfortable with the top‐cut applied (based on
what appears to be a distinct change in
population statistics) the influence of the
higher‐grade needs additional review. The
confidence in the mineral resource is defined
by the classification adopted as per the
guidelines of the 2012 JORC code.

APPENDIX 2 Excerpt on Mineral Resource Reporting from Datageo Geological Consultants’ report called

Empire Resources Ltd Penny’s Find Deposit Mineral Resource Update August 2015

“17.0 Resource Reporting Criteria, Risk and Comments

17.1 Reporting Criteria

The data and interpretation utilised and the resultant mineral resource estimate for the Penny’s Find Deposit is summarised as follows: -

  • Geology and Mineralisation Interpretation

  • The deposit consists of a moderate to steeply easterly dipping north-south striking (relative to a local grid) sheared quartz/carbonate zone which is anomalous in gold. Within the shear are zones of similarly orientated higher-grade and near surface both within the shear and adjacent are some flat lying supergene style enrichments. The Shear is mineralised over a strike length of 450m, a depth of 250m and a true width in the largest most continuous zone which averages between 2 and 10m. The Deposit remains open at depth although appears to be thinning.

  • The mineralised zones are defined using a nominal 0.5g/t Au boundary and a 2m down hole minimum length. These zones are wireframed as solids.

  • The weathering profile is positioned by the drill log information and represented by wireframed surfaces, including base of soil cover.

  • The main lithological units are interpreted on section and wireframed as solids with truncation (if appropriate) according to interpreted positions of proposed faults.

  • Drill Information and Sampling

  • The deposit has been drilled from surface using RAB, reverse circulation (RC) and diamond coring. Only the drilling from 2007, 2012 and 2015 has been used in this estimate. A total of 109 RC and diamond holes containing 11,734m has been used in the mineral estimate.

  • The core recovery is generally very good, averaging more than 95%. The RC sample recovery for the 2007 and 2012 drilling is erratic being described as good (thought to be >75% recovery) in dry conditions which is most of the time and within the mineralised zone to poor (thought to be < 25%) in wet conditions. For the 2015 drilling it averaged 84%.

  • Hole collars have been surveyed by DGPS and the orientation and inclination at collar is set out using compass and clinometer. Down hole survey for the 2007 series holes was by down hole camera measuring dip only except for the last holes of the program where dip and azimuth were measured. The 2012 program was down hole surveyed by camera with dip only recorded. Diamond tails were surveyed by gyroscopic methods. For the 2015 drilling collars were positioned by tape and compass (for existing holes) or by handheld GPS. The inclined hole was orientated using compass, sighter pegs and clinometer.

  • The drilling and sample collection techniques consisted of RC chip collected at 1m intervals via the cyclone into sample bags with on some occasions a rotary or cone splitter used to collect a smaller sample at the same time. Samples for dispatch were either composites (individual samples speared and 4 consecutive samples were combined) or individual (the 1m rotary or cone split samples were sent initially if the material returned was obviously mineralised). If the 4m composites returned an assay above a threshold then the large samples were re-speared or the rotary splitter sample was taken and submitted individually. The RC chips are logged for mineral content and geology. The core is stored in core boxes labelled with the hole number and length contained. The core is transported to the core storage area where it is logged

geologically and intervals for analysis are marked up by the site geologist. The intervals selected for analysis had the core ½ed at site to be sent for preparation and analysis. In the 2012 and 2015 drilling program Standards and Blanks were included with the samples dispatched for analysis.

  • Sample Preparation and Analysis

  • Drill samples have been prepared and analysed at commercial accredited laboratories in Western Australia

  • the preparation is by drying, crushing, riffling and pulverising.

  • gold content is determined FA techniques with atomic absorption or ICP finish. Some SFA analysis has been carried out.

  • When utilised QAQC protocols included 1 standard and 1 blank with every 12 routine samples (approximately) submitted to the laboratory. An umpire laboratory was occasionally used as were field duplicates to assist in analytical validation

  • Estimation Methodology

  • The drill hole information is composited within the mineralisation interpretation to the most common sample length within the dataset – 1m down hole

  • Grade is estimated by ordinary kriging for the largest zones with demonstrated continuity and sufficient composite information from composite data top-cut by individual zone, 25g/t ranging down to 10g/t. Other zones are estimated by inverse distance to the power of 3 techniques or when there is < 10 composites by assigning a grade of the average of the composites. The estimation is constrained by a hard boundaries representing the extent of the mineralisation and in zones with distorted population statistics (even after top-cutting) grade restrictions on the higher grade. The grade is estimated into a block model with a parent cell size of 5mE x 10mN x 5mRL.

  • Specific gravity is assigned to the block model by weathering profile position and, in the fresh zone, by reference to the position of the shear zone. A background value is assigned by rock type.

  • Validation and Classification

  • The block grade estimates are validated against the composite both globally (for all zones) and spatially for the largest zone

  • The block estimates are classified according to geological confidence, length of search, number of composites, number of holes and quality of the input data. Only the largest zones were considered for anything other than an Inferred status.

  • Reporting

  • Reporting cut-off has been determined to include all material which may be by grade and position suitable for open cut mining to a depth of 100m below surface and have an in situ grade of 3g/t Au. As such it was determined to report the mineral resource at 0.5g/t Au cut-off in this region given that the boundary condition excludes the majority of sub 0.5g/t Au composites. The part of the mineral resource below 100m from surface and grading 5g/t Au in situ was deemed to have potential for economic underground mining, as such a reporting cut-off of 1.5g/t Au was chosen

  • Mining and metallurgy

  • metallurgical test work has been conducted on two very high grade samples from the Deposit. Whilst the results were positive for grinding, gravity separation and cyanide leaching the samples are not representative of what has been modelled thus only indicative conclusions can be drawn.

  • Previous scoping studies on the August 2007 and April 2014 mineral resource estimates indicated that open cut mining may be economic to a depth of 80m.

“17.2 Resource Risk

With all mineral resource estimations there is risk associated with the utilisation of interpretations reliant mostly on ‘spot’ data. This risk is quantified by the classification of the resources based on the confidence in the consistency of the underlying data and demonstrated (or not) robustness of the

interpretation. In the case of the Penny’s Find Gold Deposit there is sufficient confidence to allow DataGeo to apply the intermediate level of confidence in and around the best drilled areas of the deposit.

The risks associated with the mineral resource estimate determined for the deposit can be considered to include:

Interpretation – low to moderate risk. Whilst the overall geological and mineralisation controls are supportable the identification of higher grade within such (i.e. use of a 0.5g/t Au boundary condition) for modelling purposes relies on assumptions of continuity which statistically appear valid are not proven. The geological and mineralisation controls are reasonably well understood in terms of the overall geological setting and the mineralisation within it.

Tonnage – low risk, given the use of constraints which conform to the interpretation and the conversion factor for volume to tonnage is reasonably supported. Additional support for values used in the weathering profile needs to be established.

Grade – low to medium risk in global terms. Any uncertainty related to the high-grade spatial distribution has been handled somewhat by grade normalisation and search restrictions in the estimation process, which in the author’s opinion, are appropriate and are unlikely to produce an overestimate (in global terms) of the average grade. However the main mineralised zone is sensitive to the top-cut applied.

Confidence – medium risk. Whilst the resource estimate relies on relatively recent data which is well known in terms of position, the lack of QAQC information for the 2007 data and the apparent lowgrade bias seen in the 2012 QAQC results indicates that there is some un-certainty which is reflected in a lower classification when compared to the amount of information. Resource is reported by position relative to potential mine by open cut or underground methods thus requiring different cutoffs.

Reporting – low to moderate risk. The cut-off applied and the depth to which it is applied is supportable in term of open cut mining potential. The cut-off applied and the depth from which it is applied for underground mining is less supportable as there is little basis for it other than general experience.

As stated, the mineral resource estimate is a global estimate and thus will not be locally reliable. Also the methodology adopted will not support significantly higher reporting cut-offs which makes the reporting for underground extraction less supportable.

There are no economic criteria built into the resource estimation. The reporting cut-off adopted (0.5g/t Au) and position was selected to reflect grade required for an open pit mining operation. The cut-off for underground mining (2g/t Au) identifies material within the mineral resource below that reported for open cut mining which, based on grade alone, which may be amenable to underground mining.

In the future, studies will be required to evaluate many of the as-yet unaddressed economic factors. These may impact on the determination of the appropriate reporting cut-off, in either a positive or negative way.

The mineralisation is open at depth so potential exists to expand the global mineral resource for the deposit.

“17.3 Comments

The comments in this section reflect some requirements/recommendations to improve the mineral resource estimate: -

  • The condition of the base drill information is generally unacceptable in terms of its presentation of use in resource estimates. A centralised data base management system should be adopted which encompasses all information

  • The data within this database (when established) should be expanded to include all relevant information contained on the drill logs and the assay information should be loaded from digital originals (if possible). Source metadata should be recorded.

  • The higher grades have been treated in a way which reflects the limited knowledge of their distribution, with their influence being quite restricted and their value top-cut. This in the future (if possible) needs to be addressed by acquiring more information from the zones of the high-grade mineralisation.

  • The impact of sample recovery on grade from the RC drilling needs to be quantified

  • The potential lower grade bias seen in the SGS results (based on standard results) needs to be quantified and sensitivities run to determine the impact on modelled grade if the bias is proven real

  • Additional structural input (particularly if the interpreted faults are real and have the potential to impact on mining) may potentially aid future mine planning.

  • An accurate topographical survey needs to be undertaken

  • Specific gravity information needs to be obtained from representative locations within the deposit with emphasis on the weathered profile and the mineralisation.

  • Scoping studies should be undertaken to determine the mining characteristics of the Deposit. If underground mining is considered in such a study the mineral resource estimate reported here should be reviewed to determine its applicability to the definition of what is likely to be narrow high-grade zones suitable for underground mining.

  • Metallurgical studies need to be reflective of the gold grade likely to be returned in a mining operation

  • Down hole survey information is restricted in many holes to a dip. Whilst the holes with complete down hole do not indicate significant deviation in the azimuth there is some locational uncertainty but this is not thought to be significant. All holes in future programs should be surveyed with a device able to reflect both azimuth and dip.”

APPENDIX 3 Excerpt on Mineral Resource History from Datageo Geological Consultants’ report called

Empire Resources Ltd Penny’s Find Deposit Mineral Resource Update August 2015

“2.1 Mineral Resource History

2006 Rubystar Nominees Pty Ltd and White Gold Mining Pty Ltd

In 2006 an Inferred Mineral Resource of 68,000 tonnes @ 4g/t Au was quoted for the deposit. The reporting cut-off is not known nor are any details of the drill information utilised or the techniques applied.

2007 June Empire Resources Ltd

In June 2007 at the request of Empire DataGeo estimated the mineral resource to the standards required of the 2004 JORC Code. Based on 115 holes (RC and RAB) totalling 6,908 metres the drill holes were composited to 1m down hole against a wireframed interpretation of the higher grade mineralisation (0.5g/t Au boundary condition) within a shear zone which occurred over a strike length of 340m and to a depth of 140m. Not all drill holes intersected the mineralisation. The grade was estimated using ordinary kriging with the composite data top-cut to 25g/t Au. The mineral resource above 0.5g/t Au is shown in Table 1.

2007 August Empire Resources Ltd

In August 2007 the above mineral resource was updated to include an additional 23 RC holes totalling 3,096 metres. This mineral resource was estimated to the standards required of the 2004 JORC Code.

Thus a total of 138 holes (RC and RAB totalling 10,004 metres) were composited to 1m down hole against an updated high grade mineralisation interpretation (retaining the 0.5g/t Au boundary condition) which now extended over a strike length of 400m and to a depth of 180m. The grade was estimated using ordinary kriging with the composite data top-cut to 25g/t Au.

The mineral resource above 0.5g/t Au is shown in Table 2.

2014 March Brimstone Resources ltd

In March 2014 Brimstone Resources Ltd (Brimstone) requested DataGeo update the mineral resource to include additional drilling had been undertaken since the previous resource (August 2007) and to ensure compliance with current JORC 2012 reporting guidelines. Brimstone had “bought” into the project (in 2011) in a Joint Venture with Empire and at the time of the mineral resource estimate had earned 40% and were managers.

The additional drilling data related to a diamond drilling program carried by Empire in 2007 and a majority RC drilling program (two holes had diamond tails added) carried out in 2012 by Brimstone. After review it was determined to use only the most recent drill hole information (holes drilled by Empire and Brimstone from 2007 onwards) with the most support. A total of 104 RC and diamond holes containing 11,312m were used for the mineral resource estimate.

The mineralisation was defined as the sheared quartz host with a nominal 0.2g/t Au boundary. The mineralisation is of variable thickness (averaging between 5 and 10m) and strikes for 500m and has a drill supported maximum depth of 280m vertical metres, is outcropping and steeply east dipping. There is some evidence of supergene enrichment in the near surface weathered horizon. Minor old workings are in evidence consisting of three shafts (maximum depth 18m) and numerous trenches.

An Au grade estimate was made using Ordinary Kriging based on 1m down hole composited drill hole data within the solid model of the Shear zone top-cut to 25g/t Au with search restrictions applied to the higher grades. For the smaller zones grade was either estimated using inverse distance to the power of 3 techniques or assigned from the average grade of the composites. Top-cuts were applied if necessary to attempt to normalise the populations.

The mineral resource above a 1g/t Au cut-off is reported to a depth of 130m below surface and is shown in Table 3.

The increased tonnage at lower grade when compared to previous estimates reflects the modelling of the entire shear (and some supergene material). “
