Bowen Coking Coal Acquires Isaac River Coking Coal Project
Bowen Coking Coal Limited (“Company” ASX: BCB) has entered into an Asset Sale Agreement with Aquila Coal Pty Ltd and Eagle Downs Pty Ltd (“Vendors”) to acquire 100% of the Isaac River Coking Coal Project (“Project”). The acquisition cost is $200,000 in cash payable to the Vendors. Settlement of the Asset Sale Agreement is subject to the receipt of indicative approval from the Queensland Department of Natural Resources and Mines for the transfer of the tenements making up the Project.

The Company is pleased to have been able to secure the Project at this time, as it is complementary to its existing project portfolio (see, most recently, ASX announcement 11 October 2017) and forms part of its strategy to increase its holdings in Queensland coking coal if opportunities arise.
Project Details
The Project covers an area of 14 km[2 ] and is located in the Bowen Basin in Central Queensland, approximately 30 km west of Moranbah and 130 km southwest of Mackay. The Project consists of Mineral Development Licence 444 (“MDL 444”) and Exploration Permit for Coal 830 (“EPC 830”). BMA’s (BHP Mitsubishi Alliance) Daunia Mine is located to the immediate west, and Peabody’s Moorvale West resource is located to the immediate north of the Project. EPC 830 occurs south of MDL 444 and abuts Peabody’s Olive Downs North Project (subject to a transaction with Pembroke Resources), and is approximately 3km North of Rio Tinto’s Winchester South project. The Project is well located relative to regional infrastructure with the Peak Downs Highway located 12km north and the Goonyella rail system within 3km of the Project.
MDL 444 was first granted on 1 February 2012. The term of MDL 444 has since been renewed, and the current term commenced on 1 February 2017 and ends on 31 January 2022. EPC 830 was first granted on 9 July 2003. The term of EPC 830 has since been renewed, and the current term commenced on 9 July 2016 and ends on 8 July 2019.

The Company notes that statutory expenditure on the Project in the first 12 months is approximately $113,000 for EPC 830 and $83,000 for MDL 444. However, the Company is likely to seek to defer some of the statutory expenditure required into the following year where committed expenditure is significantly lower at around $50,000 for both MDL444 and EPC830 combined. The Company will source the exploration expenditure from its existing cash reserves and the additional exploration expenditure on the Project is not expected to have a material impact on the Company’s expenditure on its existing projects.
The Project is prospective for coal from the Leichardt seam in the Rangal Coal Measures. The Leichardt seam is the main target seam and is extensively mined in the area by numerous operating mines. The target seam was intersected in several drill holes on MDL 444 between 35m and 142m deep with seam thicknesses varying between 2m and 5.5m. (See table 1 below). The Vermont seam was also encountered in several drill holes, but is not a priority target at the moment due to lower quality, but could provide some blending optionality to proximate mines and projects.

Indicative coal quality and washability analysis have been conducted on hole E830041C only by A&B Mylec Pty Ltd, which indicated the potential for an 8.9% ash semi-soft coking coal product with a secondary thermal coal product (6900kcal air dried) at a combined total simulated yield of 87%. Further quality tests, blending options and washability analysis are planned for 2018.
No Resource estimate has been completed in accordance with the JORC Code; however, the Company will consider in the near future further exploration data to be

directly abuts MDL 444, as can be seen in Figures 1 and 2. Daunia targets the same seams from the Rangal Coal Measures (Leichhardt and Vermont) and extracts the seams via open cut mining. Drill holes and seismic lines close to the western boundary with Daunia have demonstrated the continuation of those seams into Isaac River.

Managing Director of Bowen Coking Coal, Gerhard Redelinghuys, commented on the acquisition, “Although small, the Isaac River Project is a strategic acquisition and positions Bowen Coking Coal right in amongst several large producing companies with well-established infrastructure, and this could create significant optionality in the future developments of the Project. The Board is confident that this is a very positive step for the Company and shareholders and represents excellent value.”

SECTION 1 SAMPLING TECHNIQUES AND DATA
(Criteria listed in the preceding section also apply to this section).
Criteria JORC Code Explanation
-
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
-
Sampling (e.g. submarine nodules) may warrant disclosure of detailed

40 holes in database (5 core, 35 chip), approximately 30 holes within MDL 444
-
A strict process of data collection was followed for each of the exploration campaign conducted. All partially cored drill holes were geophysically logged and photographed to assist with the drill hole validation process. A suite of geophysical logs including density, gamma, caliper, sonic, resistivity and verticality was typically run for most holes (with the exception of holes logged through the rods). Standard calibration procedures, for each of the tools used, was conducted on a regular basis.
-
All core holes were geophysically logged and photographed as mentioned previously. It was a requirement for all holes used in modelling coal quality to have associated verticality data. Coal samples were taken on 0.5 m intervals throughout the target LHD seam where possible, or on the basis of observable variations in coal quality. The immediate 20 to 30cm cm above and below the coal seam was taken for analysis for roof and floor dilution testing. Target ply recovery for the sampled coal seams was 95%. Seam recoveries were determined by measured core length versus interpreted length derived from a review of the down hole geophysics. Where seam recovery was less than 95% a redrill of the hole was required if the recovered portion was not deemed representative. The competent person reviewed the recoveries

| Auburn Arches (interrupted by the Gogango Over- | |
| folded Zone) and the Marlborough Trough. | |
| Development of the basin in the Early Permian was in | |
| the form of a half graben which subsequently became | |
| areas of regional crustal sag. Variations in | |
| depositional patterns and deformation styles occur | |
| along strike suggesting the possibility of NE trending | |
| deep seated crustal transfer faults, evidence for such | |
| occurs at the neighbouring Isaac Plains Mine. | |
| • | The target seam for this study is the Leichardt Seam |
| (Rangal Coal Measures) with an average thickness | |
| of approximately 4.5m. The seam has not been sub- | |
| divided based on plys as with current methods in | |
| nearby mines. | |
| • | Base of weathering (BW) has been picked in 41 of the |
| drill holes included within the supplied database. The | |
| sequence of weathering is generally thicker towards | |
| the north and east associated with the eastern limb of | |
| the syncline near the intrusive body. The weathered | |
| material thins to approximately 27m towards the | |
| south and west, as the topography dips towards the | |
| east. | |
| • | The base of the Tertiary (TES) has been interpreted |
| in 31 holes and modelled across the project area. | |
| The surface is relatively thin (<3m) over the entire | |
| area, with one anomalous thick section in the north of | |
| 12m. |

| 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: • easting and northing of the drill hole collar • elevation or RL (Reduced Level – elevation above sea level in meters) of the drill hole collar • dip and azimuth of the hole • down hole length and interception depth • hole 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 Person should clearly explain why this is the case. |
• All drill holes have been modelled from vertical. |
| 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 in detail. • The assumptions used for any reporting of metal equivalent values should be clearlystated. |
• All seams where multiple coal quality samples were taken and given a composite value (generated within Minescape software) weighting each quality by thickness and insitu density, except for insitu density which is weighted on thickness. |
| Relationship between Mineralisation Widths & 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 not known‟). |
• The current data within the Isaac River area demonstrates a continuity of thickness and coal quality throughout MDL 444 |

| 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. |
• The bore hole locations are shown in Figure 1.1 |
| Balanced Reporting |
• Where comprehensive reporting of all Exploration Results is not practicable, representative reporting of both low and high grades and/or widths should be practiced to avoid misleading reporting of Exploration Results. |
• All exploration results, including coal quality lab results, within the Isaac River area have been fully collated and reported to Xenith. |
| 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. |
• Geotechnical logging, sampling, and testing from the overburden, interburden, was not done within the scope of the previous drilling programs. • Seismic Surveys were conducted by the previous holder (Aquila Coal Pty Ltd) in June 2014. Lines included 2 across strike (east-west), and 2 along strike (north-south) for 11.6km. |
| 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 this information is not commerciallysensitive. |
• Aquila Coal Pty Ltd has not conducted any recent work on this project. |
