ASX ANNOUNCEMENT
New target areas identified at Broadmeadow East Coking Coal Project
-
New drilling confirms extension of the Leichhardt seam to the south of existing Measured Resource area
-
Scout drilling intersected the Vermont Lower seam in a previously unexplored area
-
Washability and coal quality analysis underway
Bowen Coking Coal Ltd (ASX: BCB) has identified two additional targets at its 100%‐owned Broadmeadow East Project in Queensland’s prolific Bowen Basin following the completion of its coal quality drilling program.
New drilling has confirmed that the Leichhardt seam extends into the area south of the existing Measured Resource area of the project[1] , which sits within a granted Mining Lease and has a current JORC Resource estimate of 33 million tonnes. Two drill holes in this previously unexplored area encountered the Leichhardt seam at depths of 52m and 62m respectively and importantly, it has thickened to a 4m seam in this area.
Bowen Coking Coal Managing Director and CEO, Mr Gerhard Redelinghuys, said “ Broadmeadow East is the most advanced project in our portfolio of near‐term coking coal projects. Our recent drilling campaign forms an important part of our work to get it ready for production as soon as possible. Further coal quality analysis will be completed on a ply‐by‐ply basis however, initial indications from the raw coal data support our view that the lower section of the Leichhardt seam contains better coking properties and a higher yield which will enable us to tailor our mining method and optimise the quality of coking coal we produce .”
Scout drilling also intersected the previously unexplored Vermont Lower (“VL”) seam in two holes from as shallow as 36.1m. The cored section of the seam in hole CBQ0012 was 2.4m thick, which includes a 0.5m thick tuff parting. Core from this hole was obtained late in the program and therefore results will lag those of the Leichhardt seam cores. The full Girrah seam was also cored and will undergo the same tests as the Vermont Lower seam.
The results of the exploration program will now be incorporated into the geological model to support further mine planning, which could now include an extension to the proposed mine layout previously bound by the Measured Resource area[*1] north of the power line.

The objectives of the program included obtaining six core samples from the Leichhardt seam for detailed coal quality analysis on a ply‐by‐ply basis in order to maximise value from different products, as well as providing valuable information for marketing studies and potential off‐take agreements. Further analysis will be completed on receipt of the clean coal washability analysis however initial indications from the raw coal data support Bowen’s view that the lower section of the Leichhardt seam contains better coking properties and a higher yield and justifies investigation of a two‐pass mining method. Previous coal quality analysis had been limited to an aggregated total seam analysis.
Further intersections in holes CQBE006 and CQBE008 south of the power line (which bounds the current area for Measured Resources) have now confirmed seam continuance in this area, giving higher confidence in the potential for expanding the mine plan into that area. Six water monitoring bores as well as one geotechnical hole were successfully completed. These will be used to supplement the Environmental Authority (EA) amendment application. Rehabilitation of some legacy drill holes outside the mine plan area was also undertaken.

Seam intersections were consistent with expectations based on historic exploration data of most holes. Results from hole CQBE003 indicate part of the lower working section have been affected by an intrusion. Although raw coal quality data compares favourably with historic data, the ply analysis indicates a distinct quality difference between the upper and lower working section of the Leichhardt seam and therefore the full spectrum of fast float, washability and clean coal analysis will be undertaken on both working sections. Furthermore, raw coal quality analysis for the Vermont Lower and Girrah seams are underway, which could provide valuable information towards assessing the seams’ potential.
Further results will be announced to the market in coming weeks.
The Board of the Company has authorised the release of this announcement to the market.

APPENDIX A: TABLE 1
This Appendix details sections 1, 2 of the JORC Code 2012 Edition Table 1. Section 3 ‘Estimation and Reporting of Mineral Resources’, Section 4 ‘Estimation and Reporting of Ore Reserves’ and Section 5 ‘Estimation and Report of Diamonds and Other Gemstones’ have been excluded as they are not applicable to this deposit and they are not applicable to this ASX announcement.
SECTION 1 SAMPLING TECHNIQUES AND DATA
(Criteria listed in the preceding section also apply to this section.)
| Criteria | JORC Code Explanation | CP Comments |
|---|---|---|
| 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 of detailed information. |
Historical drilling and sampling data has been provided by Peabody Energy under a Confidentiality Agreement with Bowen Coking Coal in early 2020. No drilling has been undertaken on the subject mining lease since 2006. Peabody Exploration 2005/2006 All core holes were geophysically logged and photographed. Verticality data is available, but the holes are generally shallow and have been loaded into the model as vertical. All the slimcores (63mm) were logged in detail, photographed and sampled immediately into plies prior to storage in a freezer. Seam roof and floor samples 150mm in length were recovered from the Peabody Energy holes. The coal core samples were stored in the freezer to prevent the coal from oxidising. Target ply recovery for the sampled coal seams was 95% (for both slimcore and large diameter). Seam recoveries were determined by measured core length versus interpreted length derived from a review of the downhole geophysics. Where seam recovery was less than 95% a redrill of the hole was required if the recovered portion was not deemed representative. Two holes were redrilled. Four large diameter (150mm) cores holes were drilled in the Broadmeadow East ML area for washability and marketing studies of the Leichhardt seam (BL) only. All the large diameter core holes were drilled adjacent to slimcore holes for comparison of test results. The large cores were logged in detail, photographed and sampled immediately into plies and stored in 200 litre drums for storage and transport. No sampling information has been made available for the historic drilling prior to Peabody acquiring Broadmeadow East ML. |

| Criteria | JORC Code Explanation | CP Comments |
|---|---|---|
| December 2020 drilling consisted of seven 100mm conventional core holes. Holes were planned adjacent to pre‐existing chip and core holes, or drilled adjacent to a pilot hole where confidence in the geological constraints were low (south of the power line). |
||
| 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.). |
Most non‐core structure holes and the rotary slimcore drillholes (excluding LOX holes) were pre‐collared to casing depth with a either a 143mm (55/8”) or 171mm (63/4”) stabilised drag bit, and 125mm PVC casing run to 1m to 2m below the Base of Weathering. Below casing, 120mm (43/4”) tungsten‐edged blade bits were used when slimcoring was carried out on air and water using a triple‐tube HMLC (63mm) core barrel with tungsten core bit. The four large diameter core holes were all pre‐ collared with 356mm (14”) stabilised blade bits and short pieces of steel casing (255mm) were run to stabilise the surface sediments. Below casing, the holes were pre‐collared to core point using a 254mm (10”) hammer bit. The large diameter cores were recovered using a triple‐tube (nominal 150mm) core barrel with tungsten core bit. |
| Drill Sample Recovery |
Method of recording and assessing core and chip sample recoveries and results assessed. Measures taken to maximise sample recovery and ensure representative nature of the samples. Whether a relationship exists between sample recovery and grade and whether sample bias may have occurred due to preferential loss/gain of fine/coarse material. |
Peabody Exploration 2005/2006 A total of 17 slimcore holes were drilled by the Peabody in the Broadmeadow East ML area, of which 15 were analysed for coal quality of the Rangal Coal Measures seams. All slimcores were recovered by rotary tungsten (63mm) coring methods. The core recovery for these holes ranged from 97.25% to 100.00% with two re‐drills required to satisfy the coal recovery criteria (≥95%). Four large diameter (150mm) cores holes were drilled in the Broadmeadow East ML area for washability and marketing studies of the Leichhardt seam (BL) only. Core recoveries of the large diameter cores averaged 99.7%. |
| Logging | Whether core and chip samples have been geologically and geotechnically logged to a level of detail to support appropriate Mineral Resource estimation, mining studies and metallurgical studies. Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc.) photography. |
Geophysical logging of the Thiess Peabody Mitsui (TPM) and Thiess Dampier Mitsui Coal Pty Ltd (TDM) exploration drillholes (1967 to 1978) was not undertaken either because the method was unavailable at the time or the technique was in its infancy in application and was not deemed reliable. All cores were geologically logged; geological/geotechnical features identified were reported. |

| The total length and percentage of the relevant intersections logged. |
All cores holes were logged in detail and photographed. All slimcore holes were geophysically logged with natural gamma, long and short spaced density, multi‐ channel sonic, neutron, caliper and verticality logs. Large diameter and LOX holes were geophysically logged with dual density, caliper, natural gamma, and verticality logs. December 2020 Drilling Core holes during the December 2020 campaign were geophysically logged with density, gamma, sonic, verticality with an additional Acoustic Televiewer tool. All overburden chip samples were photographed, and core sections were photographed at 50cm section intervals. |
|
| 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 representivity 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. |
The analytical work for slimcores recovered and sampled by Portman Mining Limited (PML) were divided between the SGS laboratory in Mackay and the ACIRL laboratory in Riverview. The Peabody slimcore analytical work was undertaken by SGS and the ACTEST laboratories in Mackay. All the slimcores were sampled immediately into plies prior to storage in a freezer. Seam roof and floor samples, ~150mm in length, were recovered from the PEAC holes to supplement the existing roof and floor studies. The coal core samples were stored in the freezer to prevent the coal from oxidising. The analytical work for the large diameter cores recovered and sampled by Peabody was undertaken by ACIRL. The large cores were sampled immediately into plies and stored in 200 litre drums for storage and transport. Seam roof and floor samples, 150mm in length, were recovered from most of the large core for mining dilution studies. December 2020 Drilling Approximately 15cm of roof and floor was sampled above and below the target seam. Sampling of the coal seams was based on the identification stone bands and brightness differences according to sampling guidelines. |
| Quality of Assay Data and Laboratory Tests |
The nature, quality and appropriateness of the assaying and laboratory procedures used and whether the technique is considered partial or total. |
The coal quality laboratories used historically, SGS (Mackay) and ACIRL both comply with Australian Standards for all coal quality tests and is certified by the National Association of Testing Authorities, Australia (NATA). |

| For geophysical tools, spectrometers, handheld XRF instruments, etc., the parameters used in determining the analysis including instrument make and model, reading times, calibrations factors applied and their derivation, etc. Nature of quality control procedures adopted (e.g. standards, blanks, duplicates, external laboratory checks) and whether acceptable levels of accuracy (i.e. lack of bias) and precision have been established. |
No audit, or calibration of instruments used for geophysical logging was sighted for this report or provided with the dataset. Bureau Veritas (Mackay) has been utilised to provide analyses for the December 2020 drilling program. Bureau Veritas complies with Australian Standards for all coal quality tests and is certified by the National Association of Testing Authorities, Australia (NATA). |
|
| Verification of Sampling and Assaying |
The verification of significant intersections by either independent or alternative company personnel. The use of twinned holes. Documentation of primary data, data entry procedures, data verification, data storage (physical and electronic) protocols. Discuss any adjustment to assay data. |
The coal quality assays relied on data provided by Peabody. Central to which is a quality and washability database compiled by Mr Dave Hornsby (Minserve) for Peabody. Mr Hornsby confirmed the validity in discussions with Xenith Consulting Pty Ltd personnel before inclusion into the geological model and resource estimate. Review of the 2020 raw coal quality results has been undertaken by M Resources and is considered valid. |
| Location of Data Points |
Accuracy and quality of surveys used to locate drill holes (collar and down‐ hole surveys), trenches, mine workings and other locations used in Mineral Resource estimation. Specification of the grid system used. Quality and adequacy of topographic control. |
Early survey work at Broadmeadow East ML by TPM and TDM was tied to the Australian Map Grid (AMG) and Australian Height Datum (AHD) using the World Geodetic Surface (WGS) 66. Attempts to locate these holes were unsuccessful. In 1996, 1999, 2005 and 2006 all the proposed drillhole locations were set out and re‐surveyed after drilling by contract surveyors Pioneer Surveys Pty Ltd of Mackay. Survey control for the area was established from the Burton Mine mining lease boundary control along the haul road and additional haul road survey markers All survey is tied to AMG and AHD (AMG84 zone 55). December 2020 borehole survey was conducted by Airmap 3D and was picked up in AMG84 zone 55 with AHD height datum (Ausgeoid09) and was tied to the Burton Control Network ‘BD ROM’. |

|---|---|---|
| Data Spacing and Distribution |
Data spacing for reporting of Exploration Results. Whether the data spacing, and distribution is sufficient to establish the degree of geological and grade continuity appropriate for the Mineral Resource and Ore Reserve estimation procedure(s) and classifications applied. Whether sample compositing has been applied. |
Drill hole spacing has been dictated by the characteristics and consistency of the target seams within the deposit. Considering the continuity of the target seam(s) in the deposit, this spacing has proven to be sufficient to give adequate control to the model and give the required confidence in the geological interpretation. 2020 drill hole spacing target previously drilled historic holes approximately 200 to 250m apart distributed across the open cut area. |
| Orientation of Data in Relation to Geological Structure |
Whether the orientation of sampling achieves unbiased sampling of possible structures and the extent to which this is known, considering the deposit type. If the relationship between the drilling orientation and the orientation of key mineralised structures is considered to have introduced a sampling bias, this should be assessed and reported if material. |
The orientation and spacing of the drilling grid are deemed to be suitable to detect geological structures and coal seam continuity within the resource area. |
| Sample Security |
The measures taken to ensure sample security. |
No information has been sighted as to the chain of custody procedures of the previous owners of the project. 2020 chain of custody was handled by operational personnel. Core samples were taken to BV Moranbah and kept in a refrigerator prior to being shipped by BV personnel to BV Mackay for analysis. |
| Audits or Reviews |
The results of any audits or reviews of sampling techniques and data. |
There are no result or information pertaining to auditing of the sampling undertaken in previous drilling campaigns. A review of the 2020 drilling data is yet to be completed prior to adding the geological data into the existing model. This is scheduled for February 2020. |

SECTION 2 REPORTING OF EXPLORATION RESULTS
(Criteria listed in the preceding section also apply to this section.)
| Criteria | JORC Code Explanation | CP Comments | |
|---|---|---|---|
| Mineral Tenement and Land Tenure Status |
Type, reference name/number, location and ownership including agreements or material issues with third parties such as joint ventures, partnerships, overriding royalties, native title interests, historical sites, wilderness or national park and environmental settings. The security of the tenure held at the time of reporting along with any known impediments to obtaining a licence to operate in the area. |
The coal deposit is covered by mining lease, ML70257 (Broadmeadow East) which lies to the east of the Burton to Mallawa haul road and covers an area of 9.47km2. The Broadmeadow East ML represents the southern portion of the Broadmeadow deposit south of Hat Creek and is located approximately 185km southwest of Mackay by road and 25km northeast of Moranbah. Peabody (Burton Coal) Pty Ltd owns 100% of ML 70527. Bowen Coking Coal are in the final stages of acquiring this lease from Peabody.

| Exploration Done by Other Parties |
Acknowledgment and appraisal of exploration by other parties. |
A total of 29 holes were drilled from 1967 to 1978 in the Broadmeadow East ML area to assess the opencut coking coal potential. This drilling was conducted by Thiess Peabody Mitsui (TPM) and then Thiess Dampier Mitsui (TDM). In June/July 1996, Portman Mining Limited (PML) initially drilled 6 scout holes at four locations along the strike of the Broadmeadow East ML deposit to broadly confirm the earlier exploration observations and develop a broad understanding of the coal quality. Drilled metres totalled 391.0m, of which 88.46m were cored. The 1999 exploration program conducted by PML within the Broadmeadow East ML area of the Broadmeadow deposit was undertaken from May 1999 to July 1999. A total of 27 holes were drilled for a total meterage of 1,380.49m of which 63.01m were cored. In 2004, two structural holes and three LOX holes were drilled to the south of Hat Creek. A total of 193.24m of drilling was completed. |

| Geology | Deposit type, geological setting and style of mineralisation. |
The Broadmeadow East ML deposit area occurs within a structurally complex zone on the eastern side of the Collinsville Shelf in the north Bowen Basin. The deposit is located on the eastern upthrown side of the Burton Range Fault,a regional scale meridional mid‐Triassic thrust fault |

| which lies to the west of the Broadmeadow mining leases and trends in a north‐northwesterly direction. The economic coal seams in the north Bowen Basin lie within the Permian Blackwater and Back Creek Group. The Blackwater Group comprises two late Permian coal‐ bearing sequences; the Fort Cooper Coal Measures and the Rangal Coal Measures, while the Back Creek Group contains the Moranbah Coal Measures. The economic Burton Coal Project deposits occur within the Rangal Coal Measures. The Rangal Coal Measures contain the only economic coal seams in the Broadmeadow East ML area of which only the Leichhardt seam (BL), with an average thickness of between 3.5 and 4.0m is considered potentially commercial. A zone of igneous sill has been defined from holes on ML70252, to the west of ML70257. This zone is expected to continue into the very northern part of ML70257. With the current drillhole spacing it is unlikely that the igneous intrusions are extensive. A total of 3 holes have intersected igneous rocks, thought to be dolerite dykes on ML70257 itself. |

| 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 metres) 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. |
A detailed list of the drill holes used to define the coal quality of the resource in the Broadmeadow East ML deposit can be found in Section1 (Table 1) above. Coordinate information and working section thickness intercepts for the December 2020 drilling are outlined in Section 1 (Table 2) above All drill holes have been modelled from vertical. |
| Data Aggregation Methods |
In reporting Exploration Results, weighting averaging techniques, maximum and/or |
It is reported that all seams where multiple coal quality samples were taken were given composite coal quality values based on top and bottom plies. |

| 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 clearly stated. |
Coal quality samples were weighted on thickness (length) and relative density and composited on a per seam basis. Seams with a raw ash (adb) above 50% are not classified as coal and has not been included as a resource. |
|
|---|---|---|
| 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 not known’). |
All holes were drilled vertical and verticality information has been applied to modelled holes where available. |
| 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. |
A plan of the drilling locations is included in Section 2 (Figure 1) below |
| 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 available exploration data for the Broadmeadow East ML area has been collated and reported. |
18
==> picture [64 x 65] intentionally omitted <==
| 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. |
All exploration data was gathered and or utilised in the previous geological model. |
|---|---|---|
| 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 commercially sensitive. |
Further work may include additional coal quality coring, structure holes, sub‐crop drilling as well as geotechnical investigations. |
