Maiden High-Grade Eldorado Mineral Resource Estimate 445Kt @ 4.9 g/t for 69,800 oz of Gold

Eldorado Deposit, Tennant Creek – Maiden JORC 2012 High-grade Mineral Resource Estimate

o Mineral Resource Estimate of 444,700t @ 4.9 g/t gold for 69,800 oz of Gold completed including:

Indicated Resource of 277,500t @ 6.2 g/t gold for 55,600 oz of gold

Inferred Resource of 167,200 @ 2.6 g/t gold for 14,200 oz of gold

o Extremely high grade zones modelled below the Turner Fault with 16,000t @ 67.1 g/t gold for 34,500oz defined and classified as Indicated Mineral Resource

o Emmerson’s Tennant Creek Project Global Mineral Resource expanded to 2.27Mt @ 5.2 g/t for 376,600 oz of gold :

o Development studies to advance Eldorado planned

Emmerson’s Managing Director, Mike Dunbar commented:

“Emmerson’s high-grade gold inventory continues rapidly growing: The completion of the maiden Eldorado Mineral Resource Estimate is another substantial step forward for Emmerson’s Tennant Creek Project as a whole, as it adds more high-grade gold ounces to the Company’s inventory, which now stands at over 370,000oz of gold at 5.2 g/t gold with the Indicated portion of the Mineral Resource now standing at over 310,000oz of gold at 6.1g/t.

“Importantly the Eldorado resource is very robust with 80% of the resource classified as Indicated, which, given the high-grade, should allow a substantial amount of the resource to convert to an Ore Reserve, once additional development studies are completed. The Eldorado studies along with the Golden Forty development studies, which are already being completed, by our Joint Venture partner, Tennant Consolidated Mining Group (TCMG), are expected to lead to a substantial increase in the Probable Ore Reserves.

“It is expected that once these studies are completed, the deposits will be transferred into our “small mines joint venture” (SMJV), where Emmerson receives a 6% gross royalty on all gold produced from the project.

“We expect that the Eldorado resource along with the recently announced Golden Forty resource, will have a material impact on TCMG’s plans to revitalise gold mining and processing in the high-grade Tennant Creek Mineral Field and add significantly to the royalties that Emmerson will receive as well as benefiting the Northern Territory.”

Estimation of Mineral Resource for the High-Grade Eldorado Gold Deposit

Emmerson Resources Limited (Emmerson or Company ASX: ERM) is pleased to advise the completion of an initial Mineral Resource Estimate (MRE) for the Eldorado deposit within the Tennant Creek Mineral Field (TCMF), Northern Territory (Figure 1). The MRE is an important step forward in the evaluation of the deposit and will form the basis for development studies which are being undertaken by our joint venture partner Tennant Consolidated Mining Group (TCMG) as part of their plans to revitalise mining in the Tennant Creek Mineral Field.

The Eldorado MRE includes 444,700t @ 4.9 g/t gold for 69,800oz of contained gold using a variable cutoff grade of 0.5g/t gold for the shallow portion of the deposit and a 1.0g/t cutoff below 285mRL with approximately 80% of the ounces classified as Indicated (Table 1 & Figures 2 to 4). The historical mining voids have been modelled and excluded from the resource.

Importantly, the deposit is relatively insensitive to cutoff grade with the global resource ounces only decreasing by approximately 2% and 7% when the cutoff grade is increased from 0.5g/t to 1.0 and 1.5 g/t respectively (see Table 2 and a grade tonnage curve Figure 5).

Included within the resource are two extremely high grade zones at depth, which combined host 16,000t @ 67.1 g/t gold for 34,500oz , all of which is classified as Indicated. This highlights the very high-grade and consistent nature of the mineralisation and the potential for the high-grade mineralisation to be mined using underground mining methods.

With the Eldorado MRE now completed, Emmerson’s Tennant Creek Project now contains high-grade resources of 376,600oz @ 5.2g/t gold with 83% of the ounces ( 312,000oz @ 6.1g/t ) classified as Indicated (see Table 3 for MRE breakdown).

Geology and Geological Information

The Eldorado Project is located 4 kilometres south-southeast of the Tennant Creek Township.

Tennant Creek Au-Cu-Bi mineralisation is typically hosted in hematite-magnetite-quartz-jasper ironstones within the Lower Proterozoic Warramunga Formation.

The Eldorado Mine is situated in a West-Northwest trending structural corridor located within the Mt Samuel-Eldorado-Juno and Nobles Nob mineralised corridor. The gold-bearing ironstone bodies at Eldorado strike NE-SW, are north- dipping and north-east plunging. Eldorado produced 122,000oz of gold at a head grade of approximately 20g/t gold from 1935 to 1991, with the last production from open cut mining in early 1991.

The ironstone bodies are commonly truncated and offset by a series of faults. A late thrust fault (Turner Fault) displaced the upper part of the Eldorado deposit ~70m west-southwest relative to the Eldorado ‘Deeps’ part.

Drilling below the Turner Fault outlined five narrow high grade ore pods which occur between 140m to 200m below surface and dip at 60 degrees to the NNE and are generally conformable with the ironstone lode.

The geological interpretation of the deposit is based on detailed logging and sampling combined with a 3D model of the lithology domains. The high-density Reverse Circulation (RC) and Diamond Drilling (DDH) throughout the deposit has supported the development of this geological model plus a robust understanding of the distribution of mineralisation.

Drilling Techniques

Historical drilling from 1950 until 2014, a combination of underground and surface diamond, reverse circulation, percussion, vacuum and RAB rigs were used by Australian Development Limited (ADL), Poseidon Gold, Normandy and Geopeko.

Since 2014, Emmerson have used a combination of RC and surface diamond rigs.

EMMERSON RESOURCES LIMITED

Page 6 of 21

==> picture [86 x 46] intentionally omitted <==

The hole types within the deposit include seven percussion, nine vacuum, nine RAB, 5 combined RC-DDH, 125 RC and 80 diamond holes. This includes ten underground diamond holes.

The Eldorado MRE is based on logging and sampling of 236 drill holes with approximately 9,700 metres of diamond and RC drilling sampled. Sample lengths for diamond core were typically 1m intervals with ranges of 0.30m to 1.53m.

Sampling and Sub-sampling techniques

While there is limited documented information for historical sampling techniques, the Company has a detailed library of hard copy historical records dating back to the 1960’s which outline the drilling techniques, geological data and analytical information for the deposit. For the recent Emmerson drilling, there has been systematic insertion of Quality Control (QC) standards, blanks and duplicates, which have been reviewed by Emmerson geologists and are considered industry standard.

RC samples by Emmerson, were collected from the drill rig’s fixed cone splitter with two sample chutes providing a sampled from each 1m and a 1m bulk sample. The 1m bulk sample is then riffle split to obtain a representative sample for each 1m interval for inclusion into a 3m composite sample, weighing approximately 3kg. Anomalous samples were then re-assayed as single 1m samples.

Diamond cores were oriented and are sampled based on geological boundaries to a maximum length of 1.5m, marked up prior to being cut using an automatic core saw. Samples are collected from the same side of drill core and dispatched for analysis. Diamond core samples weigh ~4kg.

All RC and core samples were prepared by Intertek Genalysis Laboratory in either Alice Springs or in Adelaide. Preparation involved weighing and drying the sample, crushing the sample (to 10mm) and pulverising to >85% passing at 75µm where 200g pulp samples. Pulp samples were then transported to Intertek Genalysis Laboratory in Perth, West Australia for analysis.

Samples were composited to 1m for inclusion in the resource.

Sample Analysis Method

Historical gold assays for were reported in Dwt/ton for most of the historical assay results. Conversion used from this imperial to metric measurement was undertaken: 1 Dwt/ton = 1.530612 g/t.

These historical assays were entered from historical reports into the database as part of data compilation and for estimation work purposes. Random checks of historical records against results contained within the database has been undertaken.

For historical ADL holes, an on-site laboratory at Nobles Nob was used until 1986 where analysis was carried out by fire assay using a 50g charge. A suite of ancillary elements (Bi, Cu, Pb) were also assayed by Agua Regia and Atomic Spectroscopy (AAS) finish. Procedures developed for assay quality control with field duplication and blanks were also inserted.

Emmerson field QC procedures involve the use of certified reference material (CRM) as assay standards and include blanks. Certified reference material or blanks are inserted at least every 20 samples.

During the 2014 Emmerson drill program, RC and DDH samples were sent to Genalysis in Alice Springs for analysis using code ARU25/OM907. Elements Au, Ag, Bi, Cu, Fe, Pb, Zn were analysed.

All Emmerson assays were received electronically and imported directly into Emmerson’s Datashed database.

Mineral Resource Classification

Mineral Resource classification criteria are based on the level of data informing both the geological model and grade estimation.

The Mineral Resource has been constrained to a maximum vertical depth of 160mRL, which is approximately 210m below surface. Blocks have been classified as Indicated and Inferred based on drill hole spacing, geological continuity and estimation quality parameters.

The Indicated Mineral Resource is supported by drilling with nominal 10-20m x 10-20m spacing, and predominately informed by the first estimation pass. Geological continuity is demonstrated by the geological interpretation from drilling.

The Inferred Mineral Resource was defined where there was a low to moderate level of geological confidence in geometry, there was still continuity of grade, and drill spacing was greater than 20m. Inferred blocks are informed by the first and second estimation

EMMERSON RESOURCES LIMITED

pass. Geological support was defined to a lower level of confidence in terms of continuity and extent.

Unclassified mineralisation has not been included in this Mineral Resource. This is the material that has no estimated grades above 0.5g/t gold and material unsupported by geology and drilling or zones that are considered to be too sparsely drill tested to confirm continuity of grade or geology.

Estimation Methodology

The mineralised wireframes were modelled by intrusion and vein modelling tools using Leapfrog Software. The ironstone was used as a guide for the gold mineralisation constraining wireframes (again using Leapfrog intrusion and vein modelling tools) within the ironstone and using an approximate 0.3-0.5g/t Au cut-off. Internal high grade (approx. >10g/t Au) sub-domains were modelled and estimated separately within the deeper domains. All wireframe solids were snapped to RC and diamond drillholes.

Drillhole intercepts were composited downhole to 1m lengths and gold estimation was carried out using ordinary kriging (OK), with hard boundaries between the domains. The search ellipsoids to follow the vein reference plane to improve local estimation efficiency. Caps (top-cuts) were applied to the composites prior to estimation to reduce the influence of outliers, 90g/t gold to the main shallower mineralised domain and 300g/t gold to the deeper internal high-grade sub-domain. Gold variography was undertaken on both main domains and gave a nugget of approximately 20%. Maximum ranges of between 50m and 60m were applied. Three search passes were used, with increasing search distances and decreasing minimum sample numbers employed.

Bulk density (SG) was assigned to the block model based on weathering type and lithology. The applied density values were derived from density undertaken on the diamond drill core using the water immersion method for the nearby Golden Forty deposit

Cut-off Grades

For reporting, the cut-off grades applied to the estimate was material above 0.5g/t gold for the shallow portion of the resource (above the Turner fault) and 1.0g/t for the deeper portions of the deposit.

Mining and Metallurgical Methods Parameters

Given the high-grade nature of the deposit, the MRE has not been constrained by a nominal depth, there are Reasonable Prospects of Eventual Economic Extraction for JORC compliance, as the deposit is high grade, only 10km from a proposed CIL processing facility, and has historically been mined using underground methods and processed through a standard CIL processing flowsheet.

An approximate metallurgical recovery of +92% has been assumed in determining Reasonable Prospects of Eventual Economic Extraction, based on the historical metallurgical testwork and the fact that portions of the deposit has previously been mined and processed through a standard CIL processing circuit with high recoveries.

About Emmerson Resources

Tennant Creek

Emmerson has a commanding land position and is exploring the Tennant Creek Mineral Field (TCMF), one of Australia’s highestgrade gold and copper fields that has produced over 5.5Moz of gold and 470,000t of copper from deposits including Warrego, White Devil, Orlando, Gecko, Chariot, and Golden Forty. These high-grade deposits are highly valuable exploration targets, and to date, Emmerson’s discoveries include high-grade gold at Edna Beryl and Mauretania, plus copper-gold at Goanna and Monitor and these were found utilising new technology and concepts and are the first discoveries in the TCMF for over two decades.

The rush of new tenement applications by major and junior explorers in the Tennant Creek district, not only highlights the prospectivity of the region for copper and gold but also Emmerson’s strategic ~1,800km[2] land holding.

New South Wales

Emmerson is actively exploring two early-stage gold-copper projects in NSW, identified from the application of 2D and 3D predictive targeting models.

The highly prospective Macquarie Arc in NSW hosts >80Moz gold and >13Mt copper with these resources heavily weighted to areas of outcrop or limited cover. Emmerson’s exploration projects contain many attributes of the known deposits within the Macquarie Arc but remain underexplored due to historical impediments, including overlying cover (farmlands and younger rocks) and a lack of effective historic exploration.

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

problems. Unusual commodities or
mineralisation types (e.g., submarine
nodules) may warrant disclosure of
detailed information.

The Eldorado Estimate is based on logging and sampling of 236 drill
holes. Drilling type include surface and underground DDH and RC.

Historically, ironstone units have been sampled at 1m intervals.
Typically, either no sample was taken outside ironstone lithologies or
3mm composite samples were collected by spear.

For ERM holes:

Typically, 3m composite samples are collected from collar to
start of mineralised zone. Sampled are collected directly off the
cyclone is riffle split to separate and produce two samples, with
one side going into a pre-numbered calico sample bag. The
other half are then placed back into the original sample bag and
left on site.

3m composite samples weighs from 2 – 3kg, from which a
representative sample is pulverised to produce a 10g charge for
analysis by Aqua Regia digestion/ ICP (ARU25/OM907).

1m samples were collected through zones of interest. The 1m
samples are collected directly off the cyclone and riffle split to
separate and produce two samples, with one side going into a

ADL, Poseiden Gold, Normandy and Geopeko employed sampling
protocols for sampling RC and DDH samples. These company
procedures are considered satisfactory by Emmerson geologists.

Core from historical drilling was cut in half using a brick saw. A
nominal 1m sample was collected from half core splits from the same
side of the core. Sampling was typically constrained by ironstone
boundaries.

Core from underground drill holes were sampled with the whole core
submitted for analysis.

Emmerson used standard sampling operating procedures for
sampling RC samples.

The 3m composite riffle split samples weigh from 2 – 3kg.

The 3m composite samples collected direct from the RC cyclone
weigh from 4 – 10kg.

The 1m riffle split samples weigh from 2 – 3kg.

The 1m samples collected direct from the RC cyclone weigh 4 – 7kg.

The RC and core sample sizes are considered appropriate to
represent the mineralisation on the style of mineralisation.

Standards, Blanks and Duplicates are routinely inserted in the
sampling batch for QAQC purposes.

Emmerson field QC procedures involve the use of certified reference
material (CRM’s) inserted at every 20 samples.

Duplicates are collected every 20 samples.

have been established.

Historical field QC procedures undertaken by ADL, Poseiden Gold,
Normandy and Geopeko have been documented and reviewed,
which document the use of certified reference material (CRM) as a
standard and include blanks and duplicates.

ADL used the on-site laboratory at Nobles Nob until 1986 where
analysis was carried out by fire assay using a 50g charge. A suite of
ancillary elements (Bi, Cu, Pb) were also assayed by Agua Regia
and Atomic Spectroscopy (AAS) finish. Procedures developed for
assay quality control with field duplication and blanks were also
inserted.

For Emmerson drill holes, RC samples were submitted to Intertek
Adelaide for sample preparation and analysed at Intertek Laboratory
in Perth. The sample preparation follows industry best practice.

RC samples were analysed by ARU25/OM907 method (Au, Ag, Bi
Cu, Fe, Pb, Zn). A 10g of finely pulverised sample is digested with
aqua regia acid and the resulting solution analysed for elemental
concentration by Inductive Coupled Plasma Mass Spectrometry
(ICPMS).

For samples with >2000ppb Au, the pulp samples were analysed
using FA25/OE method. A 25 g finely pulverised sample is assayed
for Au by the fire assay fusion and cupellation process with the
resulting solution analysed for gold content by ICPOES.

No downhole geophysical tools or handheld XRF instruments are
used to determine grade.

Magnetic susceptibility data are collected every 1m meter as per

Geology • Deposit type, geological setting and style of
mineralisation.

The geological understanding of the Tennant Creek Mineral Filed
(TCMF) has been advanced by detailed mapping, dating of
stratigraphic units and regional geophysical interpretation.

Tennant Creek Au-Cu-Bi mineralisation is typically hematite-
magnetite-quartz-jasper ironstones are hosted in the Lower
Proterozoic Warramunga Formation.

Eldorado Mine is situated in a West-Northwest trending structural
corridor located within the Mt Samuel-Eldorado-Juno and Nobles
Nob mineralised corridor.

The geology and mineralisation over the main Eldorado orebody
can be characterised as:

Economic mineralisation is typically hosted in brecciated
lithologies hosted in magnetite-hematite-chlorite, quartz–
hematite breccias and chlorite-hematite stringer zones.

Criteria JORC Code Explanation Commentary
The high-grade pods are typically hematite dominant.

The ironstone bodies are commonly truncated and offset by a
series of faults. A late thrust fault (Turner Fault) displaced the
upper part of the Eldorado deposit ~70m west-southwest relative
to the Eldorado ‘Deeps’ part.

The Eldorado ‘Shallows’ ore envelope is controlled by the NE-SW
trending Pug Seam (a discordant sinistral sub-vertical fault
system) and A faults with steep northwest dips and the early ESE-
WNW trending Thomas Fault and ironstones. The intersection of
these two structural orientations has produced zones of high
fractured density with coincident high-grade ore shoots located at
the intersections.

Drilling below the Turner Fault outlined five narrow high grade ore
pods which occur between 140m to 200m below surface and dip
at 60 degrees to the NNE and are generally conformable with the
ironstone lode.

Geological
interpretation

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

The high density of RC and Diamond drilling throughout the
deposit and underground mining has supported the
development of a robust geological model and
understanding of the mineralisation distribution. The
geological interpretation of the deposit is supported by
underground mapping and sampling of the host units which
have been interpreted into a 3D model of the lithology
domains.

The host rocks are generally well defined in the logged
lithology records. Geological continuity is demonstrated by
historical underground mining.

Nature of the data used and of any
assumptions made.

Data is stored in a master DataShed database. Exports

The data is considered to be robust due to effective
database management, and validation checks to verify the
quality. Original data and survey records are utilised to
validate any noted issues.

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

Alternative interpretations for the mineralisation in the
underground model have been reported as a high-grade
selective model which uses an ordinary kriged estimate
within constrained mineralisation domains. This
interpretation resulted in a highly selective high grade
Mineral Resource Estimate which does not reflect current
exploitation plans.

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

The underground gold grade estimate is wholly constrained
within the ironstone lithological unit. All geological
observations were used to guide the interpretation and
further control the trends of the Mineral Resource estimate.

The factors affecting continuity both of grade
and geology.

Gold mineralisation at Eldorado occurs as an east-plunging,
north-dipping ironstone body.

There are several ironstone bodies present at Eldorado.
These bodies have been faulted, folded, and brecciated,
consequently creating zones of gold deposition.

The gold-bearing units are typically hosted by magnetite-
haematite-rich ironstone unit with localised zones of talc-
magnetite and quartz-magnetite lithologies. Some
mineralisation is present within the chloritised halo
surrounding the ironstone.

Faulting and shearing are very localised, and as such have
not been used to constrain the mineralisation and
geological domains.
Dimensions

Resource expressed as length (along strike or
otherwise), plan width, and depth below surface

Resource

The Eldorado deposit Mineral Resource has an

The plan width of mineralised zones in the model ranges
from 10 m to 50 m for the narrower mineralisation Domains.

Of these, 39 are from within the modelled mineralised
domains. For the oxide ironstone domains 2.80 t/m3was
assigned, for transitional zones 3.40 t/m3was assigned and
for fresh, 3.71 t/m3.

A parent block of 4m (Y) x 4m (X) x 4m (Z) with sub celling

No other elements were estimated.

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

parent block size is 5m (Y) x 5m (X) x 5m (Z). This is based
upon an average drillhole spacing of 5-10 m in selected
domains opening up to 10-20m.

1989 to 1991. The selectivity implied by the current
underground MRE model is considered to be appropriate
for a bulk tonnage underground extraction style gold
deposit to be exploited.

Any assumptions about correlation between
variables.

No correlated variables have been investigated or
estimated.

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

The geological interpretation, in particular a host ironstone
unit, was used at all stages to control the estimation. It was
used to guide the orientation and shape of the mineralised
domains and the low-grade subdomains. These were then
used as boundaries for the grade estimation, using the
trend of the mineralisation and geological units to control
the search ellipse direction and the major controls on the
distribution of grade.

Internal high grade (approx. >10g/t Au) sub-domains were
modelled and estimated separately within the deeper
domains.

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

Top cuts were used in the estimate to control the over-
influence of high-grade outliers. Top cuts, where
appropriate, were applied on an individual domain basis.

Caps (top-cuts) were applied to the composites prior to
estimation to reduce the influence of outliers, 90g/t gold to
the shallower mineralised domain and 300g/t gold to the
deeper internal high-grade sub-domain

The process of validation, the checking process
used, the comparison of model data to drillhole
data, and use of reconciliation data if available.

Validation checks of the estimate occurred by way of global
and local statistical comparison, comparison of volumes of
wireframe versus the volume of the block model,
comparison of the model average grade (and general
statistics) and the declustered sample grade by domain,
swath plots by northing, easting and elevation, visual check
of drill data versus model data and comparison of global
statistics for check estimates.
Moisture
Whether the tonnages are estimated on a dry
basis or with natural moisture, and the method
of determination of the moisture content.

The tonnage was estimated on a dry basis.
Cut-off parameters
The basis of the adopted cut-off grade(s) or
quality parameters applied

For the model, a nominal lower cut-off grade of 0.3g/t gold
was utilised for interpreting geological continuity of the
mineralisation. For reporting, the cut-off grades applied to
the estimate was 0.5g/t gold for reporting above 285mRL
(approx. 105m below surface above the Turner fault) and
1.0g/t gold for the deeper domains (up to 210m below
surface).
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.

Given the high-grade nature of the deposit, the MRE has
not been constrained by a nominal depth, there are
Reasonable Prospects of Eventual Economic Extraction for
JORC compliance, as the deposit is high grade, only 10km
from a proposed CIL processing facility, and has historically
been mined using underground methods and processed
through a standard CIL processing flowsheet.
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

An approximate metallurgical recovery of +92% has been
assumed in determining Reasonable Prospects of Eventual
Economic Extraction, based on historical production data.
The mine was in production in the 1990’sand treated at a
conventional CIP gold plant. There is extensive data
supporting that gold can be extracted using conventional
processes.

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.
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 lies within leases MLC581, MLC582 and
MLC583. The Eldorado project is located in a mature gold
mining district, with mining in the area occurring over the
past 100 years. There are no major water courses in the
project area, although ephemeral streams cut across the
project.

The current assumption of waste rock being of no
environmental significance is based on local experience in
numerous greenschist facies gold deposits which contain
significant carbonate mineralogy as part of the
mineralisation and waste rock. The mineralisation is a low-
sulphidation type with limited acid forming potential.

It is assumed that surface waste dumps will be used to
store waste material and conventional storage facilities will
be used for the process plant tailings.

The deposit has been mined in the past. Existing waste
dumps are present, with no signs or records of
environmental issues.
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 was assigned following statistical analysis of on
182 measurements from the nearby Golden Forty Deposit.
For the oxide ironstone domains 2.80 t/m3was assigned, for
transitional zones 3.40 t/m3was assigned and for fresh,
3.71 t/m3.

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.

Density was measured using a standard well-documented
procedure, the immersion or Archimedes method. Density
has been calculated in both the ironstone and alteration
zones and on both mineralised and barren zones.

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

Samples taken were coded by lithology and weathering.
Averages were derived within each weathering zone and
this value then used to code the block model for the oxide
and transition zones. Results within each weathering zone
(oxide, transitional and fresh) compared well to previous
model bulk density application in the region.
Classification
The basis for the classification of the Mineral
Resources into varying confidence categories.

The Mineral Resource has been constrained to a
maximum vertical depth of approximately 210 m below
surface.

Blocks have been classified as Indicated and Inferred
based on drill hole spacing, geological continuity and
estimation quality parameters.

The Indicated Mineral Resource is supported by
drilling with nominal 10-20 m x 10-20 m spacing.
Geological continuity is demonstrated by the
geological interpretation, pit and underground
mapping and mining.

The Inferred Mineral Resource was defined where
there was a low to moderate level of geological
confidence in geometry, there was still continuity of
grade, and drill spacing was generally greater than 20
m. Geological support was defined to a lower level of
confidence in terms of continuity and extent.

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

Grade reliability, volume uncertainty and assay uncertainty
have all been considered in the assignment of Mineral
Resource categories. Consideration has been given to all
relevant factors in the classification of the Mineral
Resource.

metal values, quality, quantity, and distribution
of the data).

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

The classification reflects the Competent Person’s view of
the deposit.
Audits or reviews
The results of any audits or reviews of Mineral
Resource estimates.

No external audits have been conducted on the Mineral
Resource estimate.

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

With further drilling it is expected that there will be
variances to the tonnage, grade, and metal of the deposit.
The Competent Person expects that these variances will
not impact on the economic extraction of the deposit. One
of the main issues is continuity and thickness variations,
and these will continue to be a key focus of mining as the
deposit is exploited, and locally there will be variable
outcomes as grade control progresses. The Competent
Person considers the Mineral Resource categories to be
appropriate with respect to these risks.

It is the Competent Person’s view that this Mineral
Resource estimate is appropriate to the type of deposit and
proposed mining style. The Tennant Creek ironstone-
hosted style of mineralisation is well understood and has a
substantial mining history to underpin the decisions made in
preparing this Mineral Resource 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

The Mineral Resource classification is appropriate at the
global scale.

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

A review of production data and underground surveyed
voids of the Eldorado mine was undertaken by ERM. The
purpose of the review was to confirm spatially what ore
material had been mined previously. The review confirmed
that the 3D void model used previously was accurate based
on all historical information available.

Eldorado was mined (underground) by ADL from 1935 and
1986.
