Resource Overview
Following completion of the September 2014 initial exploration programme at Dawson West, the geological drilling (chip and core), geophysical logging, seismic and sampling data obtained has been interpreted, compiled and loaded into the Company’s database, and geologically grid modelled with Minex Software ( Figure 3, Figure 4 & Figure 9 ). Coal core was used to confirm signatures identifying coal intersections and rock-type signatures in the chip-hole geophysical logging profiles.
Coal Resources were calculated using a default density of 1.40 multiplied by the modelled coal volumes to determine tonnages. Valid seams contributing to Resources were determined by criteria including seam continuity, thickness over 0.8m, and limits for depth of weathering and areal extent ( Figure 6, Figure 7 , Figure 8 & Figure 9 ). The JORC Code Indicated Resources areal envelope extends outwards to a distance of 1000m from drillholes containing continuous seams, and similarly for Inferred category, to a distance of 2500 metres ( Figure 2, Figure 5, Table 1 & Table 4 ). Coal quality is high-volatile export-grade thermal determined from analysis of seams cored at 5 sites ( Figure 4 , Figure 10 & Figure 11 ).

Coal Quality
Particularly encouraging in the initial coal analyses is the banded bright coal character with low ash, low - sulfur and indications of swell. Raw Coal Quality was in line with expectations and it is anticipated that the final product specification (as received) will deliver high yield over 50% while producing a 7.0% ash product with an acceptable energy content of over 6,400 k/cal and low sulfur levels of under 0.5% ( Table 2 & Table 3 ).
A&B Mylec Pty Ltd has managed the coal quality process with ALS laboratories and has provided the following commentary:
“Exploration drilling for CMR’s Dawson West Coal Project has commenced, the first HQ borecore has completed analysis at the ALS Coal Richlands laboratory with a further four borecores currently being analysed . Results to date indicate that the Dawson West deposit is a high volatile bituminous coal which would make a thermal coal suitable for the export market.
The five ‘M’ seam borecores sampled to date have ply ashes ranging from 7.9% to 43.3 %ad, with the entire seam raw ash being 20.7 %ad. Full washability testing is currently in progress; however a cut-point product sample generated by Float/Sink at a low specific gravity of 1.35 suggests that a product representative of typical Hunter Valley and Gunnedah Basin thermal coals can be achieved at a yield over 50%. Product yields would naturally increase with corresponding rises in product ash. The limited data to date indicates that the Dawson West product would meet typical Newcastle export thermal coal Calorific Value GAR and GAD benchmark specification, which presently trades at around US$73.86 per metric ton FOB. All coal quality parameters including total sulfur, chlorine and HGI lie within desired quality ranges. The project is in the early stages of exploration, with laboratory analysis still in progress. Results to date should be considered indicative, pending a full resource coal quality evaluation at completion of this exploration phase.
The two ‘J’ seam borecores were sampled as three plies each, with ply ashes ranging from 10.9% to 22.4 %ad, with the entire seam raw ash being 21.3%ad. Full washability testing is currently in progress; however a cut-point product sample generated by Float/Sink at a low specific gravity of 1.35 suggests that a product representative of typical Hunter Valley and Gunnedah Basin thermal coals can be achieved at a yield over 60%. Product yields would naturally increase with corresponding rises in product ash. The limited data to date indicates that the Dawson West product would meet typical Newcastle export thermal coal Calorific Value GAR and GAD benchmark specification, which presently trades at around US$73.86 per metric ton FOB. All coal quality parameters including total sulfur, chlorine and HGI lie within desired quality ranges. The project is in the early stages of exploration, with laboratory analysis still in progress. Results to date should be considered indicative, pending a full resource coal quality evaluation at completion of this exploration phase.
Coal classification, product options and coal utilisation potential will be further assessed as more data from the drilling programme becomes available.”

CMR’s Managing Director, Nicholas Williams commented:
“This is a huge discovery for CMR and the State of Queensland as we have identified a new coal precinct that is close to Infrastructure and is only 233km from the Gladstone Port region”.
“The second phase drilling campaign has been a great success, increasing our resource confidence into the Indicated category and overall Inferred Resource significantly from the initial exploration program”.
Mr Williams added, “CMR has only explored 8% of the total project area and the project has immense scope for significant increased tonnages across the existing unexplored areas”.
“CMR will launch into a pre-feasibility study in the coming months to look into potential mining methods, transportation options and the overall economics of the project”
“From our recent success, CMR is looking into options to further advance the Dawson West Project and will be running a process to find a development partner and will be short listing candidates in the interim”.
“CMR is committed on maintaining low exploration costs, to take advantage of the current cyclical lowpoint by optimising exploration at a point where the supply of equipment and human resources is available at significant discounts to previous pricing”.

Dawson West Project Overview
The Dawson West Project is a significant new export thermal coal deposit located in an historically low-cost mining region ( Figure 1 ). Coal-bearing strata with multiple seams occur across on EPC2427 and extend >60km east-west and >35km north south, depths range from surface to >485 metres. Multiple seams have been intersected in the Moolayember Formation in every drillhole. Drilling is initially openhole chip logged, and then cored sections are taken from seams of significance. Coal cores undergo pre-treatment to determine potential sizing and handling characteristics, and then through a combination of analyses to determine the coal character and washability characteristics that determine potential products. The Dawson West Project has a JORC Code Resource of 645Mt of which 129Mt is in the Indicated category. Coal is export quality thermal high volatile bituminous type.
Dawson West Exploration Strategy
Exploration is continuing at Dawson West, with targeted drilling phases to expand JORC Code compliant coal resources. Coal analysis that is comprehensive will continue to characterises product and mineability aspects. Initial drilling has focused on the northern areas as these are closer to existing infrastructure and rail, and this will expand into unexplored areas.
To date 28 drillholes have been completed, and successfully delineated JORC Code compliant Inferred and Indicated Resources. CMR will commence a feasibility study on completion of current exploration to assess appropriate mining methods that maximise safe and economic extraction.

Appendix 1 – JORC Code, 2012 Edition – Table 1
This appendix details sections 1, 2 and 3 of the JORC Code 2012 Edition Table 1. Section 4 ‘Estimation and Reporting of Ore Reserves’ and Section 5 ‘Estimation and Reporting of Diamonds and Other Gemstones’ have been excluded as they are not applicable to this deposit and estimation.
Section 1 - Sampling Techniques and Data
(Criteria in this section apply to all succeeding sections.)
| Criteria | JORC Code explanation | Commentary |
|---|---|---|
| Sampling techniques |
• Nature and quality of sampling (e.g. cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc). These examples should not be taken as limiting the broad meaning of sampling. • Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used. • Aspects of the determination of mineralisation that are Material to the Public Report. • In cases where ‘industry standard’ work has been done this would be relatively simple(e.g. ‘reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge for fire assay’). In other cases more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralisation types (e.g. submarine nodules) may warrant disclosure ofdetailedinformation. |
• Coal testing undertaken by CMR Coal was on samples cut with HQ & 4C Core (61 & 100mm diameter). One additional historical borehole was tested (Geological Survey of Queensland (DRD7). All core sample depths were recorded according to depths maintained by the rig geologist. These depths were determined by a combination of driller depths and the geologists own recorded depths according to core loss and gain and down-hole geophysical logs. • All sampled core was double bagged and labelled on site. Samples were given unique sample numbers and documented in a sample summary sheet. • Coal seams were divided and sampled as plies on the basis of lithological characteristics within the seam, with plies consisting of 0.5 to 0.9m sections of core. 0.1 to 0.3m of seam roof and floor were also sampled directly above and below the coal seam. • Coal quality core samples were prepared and analysed using Australian Standard testing procedures (AS4264.1). • Coal quality analysis was undertaken by Australian Laboratory Services Pty Ltd (ALS) at Richlands QLD and project managed by A&B Mylec Pty Ltd. |
| Drilling techniques |
• Drill type (e.g. core, reverse circulation, open-hole hammer, rotary air blast, auger, Bangka, sonic, etc) and details (e.g. core diameter, triple or standard tube, depth of diamond tails, face- sampling bit or other type, whether core is oriented and if so, by what method, etc) |
• All quality holes were partially cored using a HQ & 4C core barrel (61 & 100 mm diameter core). • All structural holes were fully chipped open holes using blade, hammer or PCD bits. • Chips from all holes have also been logged and photographed. • A complete list of drill holes and drilling methods is contained in Appendix 2. |
| Drill sample recovery |
• Method of recording and assessing core and chip samplerecoveries andresults assessed. |

| Sub- sampling techniques and sample preparation |
• If core, whether cut or sawn and whether quarter, half or all core taken. • If non-core, whether riffled, tube sampled, rotary split, etc and whether sampled wet or dry. • For all sample types, the nature, quality and appropriateness of the sample preparation technique. • Quality control procedures adopted for all sub- sampling stages to maximise representativeness of samples. • Measures taken to ensure that the sampling is representative of the in situ material collected, including for instance results for field duplicate/second-half sampling. • Whether sample sizes are appropriate to the grain size of the material being sampled. |
• All core samples were taken as whole core samples (not halved). • Core samples were sampled dry, double bagged on site and transported to the laboratory for testing. • Australian Laboratory Services Pty Ltd (ALS) used for coal quality analysis complied with Australian Standards for sample preparation and sub-sampling AS4264.1). • Sample preparation procedures and analytical testing requirements were devised by A&B Mylec, specialists in managing coal analytical testing and interpretation of the results, and the testing programme was conducted by ALS in accordance with the supplied sample preparation flow sheets. • Prior to subdivision and testing, all core samples were either crushed to a top size of 11.2 mm as per industry practice (AS4264.1), or subjected to industry standard drop shatter and hand knap to pass 31.5mm where pre-treatment wash ability testing was required. All subsequent sample subdivisions were also proceeded by topsizereductionsteps to ensure sample |

There are 8 petroleum wells, 7 coal seam gas wells, 8 Geological Survey of Queensland (GSQ) stratigraphic boreholes, 121 water bores with coal intersections and 935 seismic lines within the broader Project region. Data from Geophysical Survey of Queensland (GSQ) and open file private company geophysical survey data covering the Project area have been compiled. Six cored holes have been drilled in the current exploration, and apart from that only one historic GSQ stratigraphic hole(1960s) intersected seams of undifferentiated coal within the Moolayember Formation in DRD 7, which was drilled to a depth of 212.45m (Gray, 1968). Seismic 2D surveys were run across part of the tenement and data were made accessible by QGC, which confirmed flat-laying strata with no significant structure at the resolution of the seismic. All exploration programs have greatly aided the exploration activities of CMR Coal providing solid background data to base theirexplorationplanning upon. |

The project area contains two distinct sedimentary basins - the Surat and Bowen Basins. The basins are separated by a major unconformity. Both basins contain coal-bearing sedimentary sequences applicable to the project area. The regional stratigraphy is broadly flat laying siliciclastic sedimentary rock sequences in a flat to undulating terrain. Local geologically young volcanic basalt lava extrusive has filled valleys in the topographic surface of Tertiary age landscape. These basaltrocks areveryweatheredinpart and occurat surface over |

| a small area of the exploration tenement. Low hills are capped with older Precipice Sandstone of Jurassic age. The older coal- bearing Triassic Moolayember Formation underlies the Precipice Sandstone, at a shallow dipping contact angle, and forms the target sequence and focus of exploration. • The Moolayember Formation was identified as a target stratigraphic unit hosting coals and described by the Geological Survey of Queensland in Report 22 (Gray, 1968). There has been little to no exploration subsequently and is thus forms a new coal explorationprospect. |

| Drill hole information |
• A summary of all information material to the understanding of the exploration results including a tabulation of the following information for all Material drill holes: oeasting and northing of the drill hole collar oelevation or RL (Reduced Level – elevation above sea level in metres) of the drill hole collar odip and azimuth of the hole odown hole length and interception depth ohole length. • If the exclusion of this information is justified on the basis that the information is not Material and this exclusion does not detract from the understanding of the report, the Competent Personshould clearly explain why thisis the case. |
• A listing of all drill holes used in the Resource Estimate is detailed in Appendix 2. • All drillholes were drilled as vertical holes and are assumed to be vertical holes for resource modelling. • Down hole geophysical logs (LAS files) were loaded to Paradigm Geophysical Geolog6 and Minex Software. Logs, section profiles and modelling derived information generated seam correlations that were input for modelling and mapping and for resource determination processing. |
| Data aggregation methods |
• In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (e.g. cutting of high grades) and cut-off grades are usually • Material and should be stated. • Where aggregate intercepts incorporate short lengths of high grade results and longer lengths of low grade results, the procedure used for such aggregation should be stated and some typical examples of such aggregations should be shown indetail. |
• All coal quality information (raw and potential product) has been composited into samples using coal industry standard methods to derive seam and ply samples for analysis and quality determinations. Washability data, yield and coal quality compositing was performed using Microsoft Excel software where each coal quality value was weighted by both in situ relative density and thickness, and washability fraction. • No minimum sample thickness cut-offs were applied as all seams contained samples of greater than 95% recovery. |

| • The assumptions used for any reporting of metal equivalentvalues should be clearly stated. |
||
| Relationship between mineralisation widths and intercept lengths |
• These relationships are particularly important in the reporting of Exploration Results. • If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported. • If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect (e.g. ‘down hole length, true width notknown’). |
• The current data within the Dawson West area demonstrates, with sufficient confidence, that the deposit has lateral continuity. As such, data has been extrapolated to a maximum of 2,500 m past the last drill hole for Inferred Resources, and 1000m for Indicated Resources. • The major seam used in the resource estimate contained consistent geophysical signatures and seam thickness of acceptable consistency within the resource area. |
| Diagrams | • Appropriate maps and sections (with scales) and tabulations of intercepts should be included for any significant discovery being reported These should include, but not be limited to a plan view of drill hole collar locations and appropriate sectional views. |
• All relevant diagrams are contained within the body of the Dawson West Project – Geology & Resource Report – July 2014. |
| Balanced reporting |
• Where comprehensive reporting of all Exploration Results is not practicable, representative reporting of both low and high grades and/or widths should be practiced to avoidmisleadingreporting of Exploration Results. |
• All exploration results within the Dawson West Project area have been collated and reported. |
| Other substantive exploration data |
• Other exploration data, if meaningful and material, should be reported including (but not limited to): geological observations; geophysical survey results; geochemical survey results; bulk samples – size and method of treatment; metallurgical test results; bulk density, groundwater, geotechnical and rock characteristics; potential deleterious or contaminating substances. |
• This is a new coal sequence exploration in Triassic age strata. This area has not been explored significantly since the early regional stratigraphic exploration by the Geological Survey of Queensland in 1968. The Moolayember Formation was identified as a target stratigraphic unit hosting coals and described by the Geological Survey of Queensland in Report 22 (Gray, 1968). |
| Further work | • The nature and scale of planned further work (e.g. tests for lateral extensions or depth extensions or large-scale step-out drilling). • Diagrams clearly highlighting the areas of possible extensions, including the main geological interpretations and future drilling areas, provided thisinformation isnot |
• CMR Coal plan on further delineating the Dawson West Project resource in 2014. A detailed infill drilling program is planned to increase the geological knowledge and confidence both structure, coal quality and potential mineability. • A 2D seismic survey is also planned to assist in the accurate determination of the basin structure and coal seam extents, especially thewesternand eastern margin limits,whichare |

| 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. • Datavalidationprocedures used. |
• CMR Coal uses LogCheck version 6.072 in the field for data storage. • Drillhole data is also validated by Rock Knowledge Services Pty Ltd and Coal Resource Consultants Pty Ltd during and after loading dataintomodelling software. |
|
| Site visits | • Comment on any site visits undertaken by the Competent Person and the outcome of those visits. • If no site visits have been undertaken indicate why this is the case. |
• CMR has undertaken many field site visits during the course of implementing the 2014 drilling and exploration programme. • Rock Knowledge Services Pty Ltd has regular meetings and internet connection with CMR Coal to discuss and review sampling and exploration design, results and field procedures to enhance data collection quality. • Geotechnical consultants, Gordon Geotechniques Pty Ltd have visited site to oversee geotechnical sampling and logging of core andreview field procedures and sampling practices. |
|
| Geological interpretati on |
• Confidence in (or conversely, the uncertainty of) the geological interpretation of the mineral deposit. • Nature of the data used and of any assumptions made. • The effect, if any, of alternative interpretations on Mineral Resource estimation. • The use of geology in guiding and controlling Mineral Resource estimation. • The factors affecting continuity both of grade and geology. |
• Down hole geophysical logs (LAS files) were loaded to Paradigm Geophysical Geolog6 Software and log and section profiles were generated from which seam correlations, contact depth and elevation attributes were determined and extracted to data files for resource modelling, sampling and processing. • The drillhole density in the Dawson West Project area allows a moderate to high level of confidence in the nature of the seam thickness and quality consistency and interpreted location of faults. • It is recommended that future exploration involve 2D seismic to assist in delineating the precise location and nature of any faults and unconformities identified. No significant structure has been found, apart from a Tertiary basalt-filled valley drainage, and the Jurassic unconformity overlying theMoolayember.. |

| 7 km north-south. This area comprises the MDL Application extent. Numerous seams ranging from 0.80 – 3.5+m thickness from depths of 5 to 487 metres occur within the explored area. The deposit straddles the centralaxis oftheTaroom Trough(Mimosa Syncline). |
||
| Estimation and modelling techniques |
• The nature and appropriateness of the estimation technique(s) applied and key assumptions, including treatment of extreme grade values, domaining, interpolation parameters and maximum distance of extrapolation from data points. If a computer assisted estimation method was chosen include a description of computer software and parameters used. • The availability of check estimates, previous estimates and/or mine production records and whether the Mineral Resource estimate takes appropriate account of such data. • The assumptions made regarding recovery of by- products. • Estimation of deleterious elements or other non- grade variables of economic significance (e.g. sulphur for acid mine drainage characterisation). • In the case of block model interpolation, the block size in relation to the average sample spacing and the search employed. • Any assumptions behind modelling of selective mining units. • Any assumptions about correlation between variables. • Description of how the geological interpretation was used to control the resource estimates. • Discussion of basis for using or not using grade cutting or capping. • The process of validation, the checking process used, the comparison of model data to drill hole data, and use of reconciliationdataifavailable. |
• Down hole geophysical logs (LAS files) were loaded by Rock Knowledge Services Pty Ltd to Paradigm Geophysical Geolog6 Software and log and section profiles were generated from which seam correlations, contact depth and elevation attributes (picks) were determined and extracted to data files for resource processing by Coal Resources Consulting Pty Ltd, using Minex Software. • The geological model and resource estimate were constructed from determination of the thickness, elevation, volume and tonnage, respectively. • Limits were placed on coal seams reporting to the JORC Resource Estimate: Depth of Weathering defines upper resource boundary Coal thickness >= 0.80 metres seam thickness Stone partings < 0.5 m (reporting table) and <0.30 m thickness Coal splits < 0.3 m thickness excluded Distance around points in contiguous points of coal intersection (drillholes) are <= 2500 metres for Inferred and <= 1000m for Indicated Resources within the tenement area. • Areas and seam components outside these constraints were blanked and did not report to the resources estimate. • A coal density of 1.40 was used for resource tonnage determination using coal volume calculated from the_‘limits_ _modified’_seam thickness grids (See Table 3). |

| Cut-off parameters |
• The basis of the adopted cut-off grade(s) or quality parameters applied. |
• No quality parameters were used to limit the Resources. • Coal washability analysis on multiple seams has yielded single cut- point analysisinformation for various seams. |
| Mining factors or assumption s |
• 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 ofthemining assumptionsmade. |
• Rock Knowledge Services Pty Ltd has applied a minimum seam thickness cut-off of 0.80 metres after consultation with CMR Coal. It is deemed that this thickness cut-off is in line with current underground mining minimum seam thickness limits. • These attributes will be refined once the mining pre-feasibility is undertaken. |
| Metallurgic al factors or assumption s |
• 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 assumptionsmade. |
• At this early stage of the project there are no limiting metallurgical factors. Full washability testing of the coal seams is yet to be completed, after which metallurgical treatment process simulations and evaluation will be performed. • A simple cut-point Float/Sink at 1.35 SG has been performed to provide an early indication of potential low ash product quality and for coal classification. |
| Environmen tal factors or assumption s |
• 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 aspectshavenot been |
• It is Rock Knowledge Services Pty Ltd opinion that there are no limiting environmental factors apparent at this stage of the project. |

| Bulk density | • Whether assumed or determined. If assumed, the basis for the assumptions. If determined, the method used, whether wet or dry, the frequency of the measurements, the nature, size and representativeness of the samples. • The bulk density for bulk material must have been measured by methods that adequately account for void spaces (vugs, porosity, etc.), moisture and differences between rock and alteration zones within the deposit. • Discuss assumptions for bulk density estimates used in the evaluation process of the different materials. |
• An in-situ default density for coal seams of 1.40 has been used. • Tonnages are estimated using a default in-situ density of 1.40. |
| Classificatio n |
• The basis for the classification of the Mineral Resources into varying confidence categories. • Whether appropriate account has been taken of all relevant factors (i.e. relative confidence in tonnage/grade estimations, reliability of input data, confidence in continuity of geology and metal values, quality, quantity and distribution of the data). • Whether the result appropriately reflects the CompetentPerson’sviewofthe deposit. |
• Two resource categories (Inferred and Indicated) have been identified in the Dawson West Project area dependent on the level of confidence in the seam structure and continuity plus the level of variability in the coal quality data. Valid points of observation (PoB) for resource categories are defined by distance around points that are part of a collection of contiguous points of coal intersection (drillholes), which are <= 2500 metres for Inferred and <= 1000m for Indicated Resources within the tenement area. |
| Audits or reviews |
• The results of any audits or reviews of Mineral Resource estimates. |
• CMR Coal and A&B Mylec were responsible for implementing and maintaining the sampling techniques and data, with peer review by Rock Knowledge Services Pty Ltd. • Australian Laboratory Services Pty Ltd (ALS) undertakes internal audits and round robins testing to ensure analytical results are reporting precisely and accurately. |
| 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 ofstatisticalorgeostatisticalprocedures to |
• Rock Knowledge Services Pty Ltd in consultation with Coal Resource Consultants Pty Ltd have assigned the Inferred and Indicated levels of confidence to the coal Resource Estimate based on the seam and drill hole spacing as detailed in the previous section ‘Resource Classification’. • Factors that could affect the accuracy oftheresource estimate |
