Mine Planning

The mine plan has been reviewed using the latest geological information and a preferred mining area has been identified. This area is sufficient to support a modern longwall mining operation and will form the basis for a mining prefeasibility study.

Figure 1 above shows the location of the conceptual mine plan.

Schedule

In September2013 Glencore Xstrata announced that they had shelved their Wandoan project. This will have the inevitable effect of delaying the start of the Surat Basin Railway (SBR). Although MTE has joined together with other Surat Basin coal companies to consider other options for the construction of the railway it is now accepted that the Bundi project will be delayed beyond our previous timetable.

In light of this delay, and in order to preserve cash, MTE has suspended further operations in the field including the EIS and no longer intends to submit the mining lease application this year. The Company will review the timetable when there is further information on the start date of the SBR and when the overall coal market and coal price improves.

About the Bundi Project

The Bundi Project Area is located in the northern part of EPC1164 and includes several sub blocks from the adjoining EPC1251 and EPC1609. The JuandahProject area is also located in EPC1164, contiguous with the south east corner of the Bundi Project. The proposed Bundi mining area is in the down dip extensions of the Kogan and Macalister Coal Seams immediately south of Xstrata’s proposed Wandoan Open Cut Mine development and New Hope Coal’s proposed Elimatta Mine.

The coal seams will be mined underground utilising a modern high productivity longwall mining system. This will produce approximately 5 Million tonnes per year of medium ash, low sulphur thermal coal suitable for steam raising in thermal power plants. This production target is based in part on Inferred Resources. There is a low level of geological confidence associated with Inferred mineral resources and there is no certainty that further exploration work will result in the determination of Indicated mineral resources or that the production target itself will be realised

The Appendix to this release details sections 1, 2 and 3 of the JORC Code Table 1.

JORC TABLE 1

Section 1: Sampling Techniques and Data

Criteria Project Details
Sampling
Techniques
HQ Core samples were analysed for raw proximate coal analysis and testing on the coreholes WW5C, WW20C,
WW25C, WW27C, WW29C, WW30C, WW32C – WW71C, WW85 – WW92C, WW98 – WW100C and WW108C –
WW165CR (up to March 2013). RD analysis was completed for samples from WW20C, WW25C, WW27C,
WW29C, WW30C and WW32C – WW71C, WW85 – WW92C and WW98 – WW100C and WW108C – WW165CR
(up to March 2013). Analysis on the MetroCoal 2013 drill cores (WW166C - WW173C) is currently underway
and results were not available at the time of report. Unsampled stone within the Bundi area has been given an
estimated stone analysis based on similar material within the section. All coal and stone within the seam has
been composited to reflect the underground mining working section. Washability results were available for
densities F1.4 to S1.6 for 26 holes selected from holes WW72C onward. WW22C had float sink results from
drilling carried out in 2009 as an initial trial to see how the material would wash. A calculated insitu density
was used over the Bundi resource area. WW5C was not included in this resource estimation due to RD not
being tested.
Drilling Techniques Details on the types of drilling methods used are available in QDEX reports and include open holes, and
partially cored HQ coreholes. Cored holes WW5C, WW08C, WW09C, WW13C, WW14C, WW20C, WW23C,
WW27C, WW29C, WW30C and WW32C-WW39C, WW40C-WW173c were all HQ3, 61mm diameter standard
tube diamond cores. Each partial partially cored HQ corehole had on average 50m of core with a tail of 20m
below the target Macalister Upper seam. To date two PQ cores, 85mm diameter (PQ1 and PQ2) have been
drilled to assess bulk washability testing on the cores. Up to end of March 2013, all cored holes up to
WW165CR have had Coal Quality analysed and tested in a NATA accredited laboratory.
Drill Sample
Recovery
Sampling strategy of the Macalister Upper Seam through the study area has generally been lithologically
based. Samples have been taken at a scale detailed enough to allow compositing into the correlated Ply’s.
Where core recovery was assessed to be excessive (<95% recovery) the hole was redrilled to ensure the entire
resourcable section was tested. Target seams were drilled to maximise that the seam was cored in one core
barrel, thus minimising coal seam loss. Working section proximate analysis composites were used to assess the
resource.
Logging All holes were lithologically logged. Brightness logging has been conducted on the coreholes in the Bundi Area.
Holes drilled in the 2008-2013 exploration programs were geophysically logged. Typically gamma, density and
calliper were run by Geoscience until late 2009 and Geolog Pty Ltd in 2010-2013. Pre 2006 holes, and
Petroleum and CSG wells used in the model were all geophysical logged including density. Density logs were
used from both LAS and PDF formats. All holes drilled in the Bundi Project have complete photos of the core
sections including a photo run board detailing core run particulars.
Sub-sampling
techniques and
sample preparation
All core is housed on site in an undercover coreshed arranged by hole ID. All coal quality core is sent to
Brisbane for analysis in whole core to ensure maximum material is present for testing (especially washability
testing) and is sealed in UV resistant plastic bags and double cable tied for transport. Only core samples were
sent for analysis. All samples from WW94C are received from the field, dried in drying racks then crushed to
11.2mm for testing. Prior to WW94C, WW series samples were initially crushed to 4mm before being split for
further tests. Samples are mixed using a rotary splitter (2 passes) to ensure homogenisation and then divided
for further analysis. Half the resulting sample is send for Washability testing (11.2mm topsize), 1/8 is sent for
Proximate Analysis and ground to -212µm for 1gm of sample per test. The remaining sample is ground to -
212µm, sealed and kept in archive for future testing.
Quality of
assay data and
laboratory tests
The WW series coal quality testing is carried out using NATA accredited laboratories for all tests conducted.
This covers instrument calibration, standardisation and reporting. To ensure acceptable levels of accuracy are
achieved, samples are sent to multiple labs (GeoConsult Pty Ltd and Preplab Pty Ltd - SGS in the past) and data
is assessed to identify any outliers. Any erroneous results are sent back to the lab for clarification. Standards
adopted include Total Moisture (AS1038.1), Ash, Inherent Moisture and Volatile Matter (AS1038.3), Calorific
Value (AS1038.5), Total Sulphur (1038.6.3.3), Relative Density (AS1038.21.1.2), Float/Sink (AS4146.1) and
Sample Preparation (AS4264.1).

Verification of
sampling and
assaying
All results are verified by both MetroCoal Ltd and GeoConsult Pty Ltd to ensure sampling in the field and
laboratory assay results are without error. MetroCoal has carried out several twinned holes to assess
variability in Coal Quality analysis over the mining section as well as several different core sizes to complete
different tests including bulk tests and DST gas tests to assess how gas impacts on the deposit. Data
accumulated from the field is stored on both MetroCoal and GeoConsult's servers back in Brisbane. Hard copy
data is filed out on site in the MetroCoal site office in Wandoan. Once data is entered digitally, both the
corrected and uncorrected data is emailed back to Brisbane for verification where it is copied to the servers.
For external review, the data is arranged into a data room which is provided to external technical staff and
potential JV partners.
Location of data
points
The database consists of a significant number of non MetroCoal holes (previous coal exploration drilling,
departmental stratigraphic drillholes, petroleum and CSG wells); Stage 1 – 2008 WW1-8 series, Stage 2 – 2009
WW9-19 series, Stage 3 – 2010 WW20C-42C, Stage 4 – 2011 WW43C-113C, Stage 5 – 2012 WW114C-165CR
have been surveyed by external, licenced surveying contractors. The 2013 drilling currently taking place
(WW166C - WW173C) will be surveyed on completion of the drilling campaign. A GPS coordinate is acquired
by the field geologist in this occurrence. The locations of the non MetroCoal holes are based on the survey
locations reported in well completion and department reports. Unrecorded and anomalous collar elevations
reported for non Metrocoal drillholes were adjusted to the 2012 MetroCoal Bundi DTM. This survey was
carried out by Fugro Spatial Solutions Pty Ltd. Both holes with surveyed and DTM collar elevations are used
for modelling resources. All hole coordinates are recorded in GDA94 - Zone 55.
Data spacing
and distribution
Drillhole spacing is variable, typically 800m. Chip holes have a variable spacing; typically 3km. 214 drillholes
with MU Seam intersections form the basis of the Bundi Area model and resource estimation. Data spacing is
sufficient to establish the degree of geological and grade continuity for a resource with >90% of holes
recording both stratigraphic and quality data with most holes drilled by MetroCoal containing LAS data
(besides WW3 which had issues with gas and had to be sealed before Geophysical logging took place). Where
a hole does not contain LAS data, the intervals can only be used in an advisory sense. Samples have been
composited using Maptek Vulcan compositing samples menu. The compositing was also manually calculated
to cross check.
Orientation of
data in relation
to geological
structure
In general, future drill programs would include the expansion of the Inferred and Indicated resource as well as
eventually defining a maiden Measured resource. This would include further Geotechnical study along with an
EIS in preparation of applying for an ML over the resource. Areas for future expansion include the eastern limb
of the deposit and continuing it down to former application MDLa 406.
Sample security All samples are stored in a locked shed while on site to ensure heat and UV do not break the sample down.
Once a batch of samples is brought back from the field and provided to the Nata accredited and ISO9000
laboratory for testing, a sample manifest is provided to the laboratory with the client name, project name,
borehole and interval tested listed on it. No sample location data is provided.
Audits or
reviews
Sampling techniques are continually being assessed to ensure best practice is being applied to the coal quality
testing on the Bundi Coal Project. Both procedures produced and applied by MetroCoal are checked by
GeoConsult to ensure they fit with the current ply model in terms of ply sampling and geotechnical roof and
floor samples. Quarterly audits take place out on site to ensure the procedures take place within specifications
and adjusted if an issue arises.

Mineral
tenement and
land tenure
status
Resources estimated are within EPC1164, EPC1251 and EPC1609 and are wholly owned by MetroCoal Pty Ltd.
Native title interests over the tenements include the Mandandanji People (QUD366/2006, QC2008/010) over
the south western portion of the resource and the Iman People #2 (QUD6162/1998, QC1997/055) over the
rest of the resource. Mt Organ State Forest lies in the middle of the resource however no drilling has taken
place in the forest at this time. Hinchley State Forest lies to the south of the resource area.
Exploration done
by other parties
Sporadic coal exploration was carried out by Xstrata (Relinquished), CSG exploration by Pure Energy (QGC) and
OCA (Relinquished) and QGC (Relinquished). See report Table 1 - Drillhole Collars for full details
Geology The coal seams within the Bundi Coal Project area form part of the Walloon Subgroup, namely the Juandah
and Taroom Coal Measures and dip gently to the south.Kogan 10, 30, 50 Seams and Macalister Upper Seam
are the conventional underground mining target seams. The Lower Macalister Seam is present, but requires
further investigation. The Macalister Lower Seam is not included in the resource estimate at this stage.
Drill hole
Information
MetroCoal drillhole data is stored in a GPAC database. The database contains all header, lithological, LAS
downhole geophysics, raw coal quality and washability data. This database is exported to Vulcan for
modelling. Up to end of July 2013, MetroCoal drillholes up to WW170C had been included in the database.
Detailed information for the boreholes within the Bundi Coal Project area is included as Depth to roof (DR) and
structure roof (SR) contour plans. All grids and values in the model take into account the borehole information
so the individual borehole results are not needed in this case.
Data
aggregation
methods
Quality analysis over the intervals have been weighted averaged (thickness - density) using the industry
standard technique. Coal and stone bands are analysed within the seam and are composited in the working
section.
Relationship
between
mineralisation
widths and
intercept lengths
A working section model is generated for the Macalister Upper Seam based on maximum parting thickness of
stone bands MU20 and MU40. Starting with the MU30, MU20 and MU10 were added to the top when MU20
was less than the maximum parting thickness of 0.5m. MU40 and MU50 were added to the floor where
MU40.ST was less than the maximum parting thickness of 0.5m. KO90 and KO99 were added to the roof
where KO99.ST was less than the maximum parting thickness of 0.5m. KO70 and KO80 were added to the roof
where KO80.ST was less than the maximum parting thickness of 0.5m and the KO90 was added previously.
MU80 and ML10 were added to the floor where MU80.ST was less than the maximum parting thickness of
0.5m. Areas where the MU10-MU20 and MU50-MU40 have been included in the working sections are defined
by the respective, MU10 and MU50 split lines. Working section grids were generated from automated scripts
as well as from manually derived and verified points.

Balanced
reporting
When reported, resource variables are expressed in an average, maximum and minimum to present an
unbiased representation of exploration results. Variables reported in this way include depth to roof (DR),
insitu density (ID), relative density (RD), structure thickness (ST), raw ash (AS%), total sulphur (TS%), inherent
moisture (IM%), calorific value (CV) and fixed carbon (FC%).
Other
substantive
exploration data
A number of studies has been undertaken to better learn the deposit. MetroCoal ran a 2D seismic survey in
2012 to identify subsurface structures as well as a LIDAR survey in 2012 to get a more accurate topographic
surface that what was freely available. MetroCoal also engaged E3 consulting to undertake a groundwater
survey with the installation of several vibrating wire peisometers.

Section 3: Estimation and Reporting of Mineral Resources

Criteria Project Details
Database
integrity
The current Bundi exploration database is stored in GeoConsult Pty Ltd's GPAC database and then exported via
ASCII to Vulcan for modelling. The data is stored by hole ID and all data is stored within the database.
Validation takes place on the data within GPAC to ensure keying errors are rectified and an english log is
produced for a manual check of the data. If information needs further QA/QC, the original hole records can be
scrutinised to rectify the issue identified. Data validation also takes place within Vulcan while modelling to
ensure no overlapping horizons occur. Once identified the errors can be amended manually.
Site visits When site operations occur, the site is visited by the CP and an exploration supervisor to ensure the data
being collected from the field is of the highest quality. Activities observed include: drill rig operations, core
markup, lithological logging, sample selection and preparation for analysis, corebox labelling and storage,
record keeping particularly in respect to lithology, core run and core loss and ensure samples and core are
stored in a suitable environment to ensure they are kept as a record. Site visits are also used to communicate
procedure changes in sampling and upcoming tests on the boreholes. The latest seam correlation and seam
sections are also prepared and brought out to site to ensure field staff know the importance of good field data
making its way to the model. A site visit will occur every three months and runs on the back of a safety audit
on the site. CP conducts annual inspections of the site to ensure sampling and ply correlation is carried out
according to the stratigraphy
Geological
interpretation
The Macalister Upper Seam correlations within the Bundi area were checked against slimline geophysical logs.
Geophysical logs including density are available for all drillholes used in the model. LAS data is available for
most drill holes post 2000. Pre 2000 has limited hard copy and PDF files. An ash-density regression was applied
to the wireline density logs to calculate an approximate ‘synthetic’ log. Correlation between CQ-ash and LAS-
ash was tested; LAS-ash working section composites reviewed for all holes, the results are supportive but,
have not been used to constrain the working section. Up to end of June 2013, all MetroCoal LAS up to
WW171C had been included in the database.
Ten seam packages were identified and correlated across the deposit. Correlation of the seams was
undertaken using geophysical logs. Modelling is based on stratigraphic units. The target Macalister Upper
Seam was correlated in detail. Ply by Ply correlation of each Macalister Upper Seam intersection within all
holes in included in the Bundi area model. Split lines where the stone bands in the seam reach >0.5m define
the resource in certain areas and can restrict the resource from reaching a minimum working section thickness
of 1.8m. Other factors such as coal quality (% raw Ash) limit the resource in places.
Dimensions The strike of the current MUWS Inferred resource is 26km west to east and following the dip is 8km. The
current MUWS Indicated resource lies in the middle of the Inferred resource and is 12km in strike and 4km in
dip. The depth to roof of the MUWS is recorded as 80m to 339m across the resource. There are resources on
other seam sections within the Kogan including the KO10, KO30 and KO50
Estimation
and modelling
techniques
A geological model was created using Vulcan software based on grid models. Grid mesh size was 50m.
Structure surfaces were generated using a triangulation, analytical grids modelled using inverse distance.
Moisture Resource tonnages were estimated on a dry basis using Insitu Densities derived from existing laboratory
testing and analysis of coal quality data. Insitu Density was also calculated using the Preston and Sanders
formula (1993).
Cut-off
parameters
In 2010, MetroCoal and GeoConsult derived a set of parameters at which the resource could be defined to
make the resulting resource a marketable grade. The grade is as follows: Maximum (ad) ash limit of up to 35%
raw ash, Minimum seam thickness of 1.8m for the Macalister Upper Seam and 1.5m for Kogan Seams,
Minimum depth of 80m (for Underground Resource) depth of cover and a maximum in seam stone parting of
0.5m. With the progression into a mining model, the parameters were kept the same except for the raising of
Maximum (ad) ash limit of up to 40% raw ash. A higher ash polygon has been included and will be assessed
with the washability data.

Mining factors
or assumptions
The Macalister Upper Seam is being targeted for underground extraction. Extraction parameters were
considered for target. Australian analogues for the conventional underground mining coal working section
heights, and depths were identified. The coal quality for the working section is comparable to other deposits
currently operating in the Surat Basin. In June 2012, MCS completed a concept mining study with the view to
draft a plan for the underground mine with panel design, equipment needed to mine, target tonnages and
initial CAPEX calculations but is currently not been made public. MCS's results do not filter back to the model
at this stage.
Metallurgical
factors or
assumptions
All raw coal quality data is stored in the ‘metwan.geo.isis’ ISIS database under the CQR tab. This dataset
contains all analysis data performed on core samples organised by hole and sample number. Where coal
quality data was unavailable for a Plies MU40 and MU50 in holes WW5C and WW27C, raw coal analysis from a
drillhole with comparable lithological and wireline geophysical characteristics was substituted. A default stone
analysis (WW37_CQ4 within MU30) has been applied for stone bands not analysed in the working section. The
default stone analyses have values for all coal quality parameters modelled. Where the default stone analysis
has been used the sample number has been denoted in the sample identification number “Hole_CQN#”. Up to
the end of March 2013, all cored holes up to WW71C, WW85 – WW92C and WW98 – WW100C and WW108C
– WW165CR had been analysed and tested in a NATA accredited laboratory and were included in the model.
Samples from WW166C - WW173C have been sent to the laboratory for analysis and results are expected
within three months.
Environmental
factors or
assumptions
In general, future drill programs would include the expansion of the Inferred and Indicated resource as well as
eventually defining a maiden Measured resource. This would include further Geotechnical study along with an
EIS in preparation of applying for an ML over the resource. Areas for future expansion include the eastern limb
of the deposit and continuing it down to former application MDLa 406.
Classification KO10 - Indicated and Inferred Resource Identified, including higher raw ash (>40%) polygons
KO30 - Indicated and Inferred Resource Identified
MUWS - Indicated and Inferred Resource Identified, including higher raw ash (>40%) polygons
Audits or
reviews.
Internal reviews and audits were undertaken. MetroCoal has also reviewed and given input into the
correlation in areas where separation between minable seams was <0.5m.
Discussion
of relative
accuracy/
confidence
GeoConsult have estimated and inferred a level of confidence to the Coal Resource Estimate depending on the
seam and drillhole spacing, as described in the section 'Resource Estimation' of this report.
Faulting is noted but not been taken into account in this resource until further infill drilling can confirm the
location. Factors that could affect accuracy could include further structure between points of observation,
errosional surfaces or in seam partings increasing in size between points of observation.
