GEOTECHNICAL RESULTS CONFIRM HIGH PRODUCTIVITY MINING POTENTIAL
HIGHLIGHTS:
-
Geotechnical analysis performed on recent drilling core targeting the WK No.9 seam confirms the potential for Buck Creek to be a high productivity underground mining operation located in the high growth Illinois Basin
-
Confirms potential mining conditions of Buck Creek to be consistent with adjacent underground mines in the region
-
Mining operations in the Illinois Basin are some of the most productive when compared to US and Australian coal basins
-
Buck Creek is one of the last undeveloped coal projects in the highly profitable WK No.9 seam of the Illinois Basin which is not controlled by a major US coal company
-
Paringa Resources Limited (“ Paringa ” or “ Company ”) is pleased to announce the results of a geotechnical study conducted by Appalachian Mining & Engineering, Inc., confirming the geology of the Buck Creek coal project (“ Buck Creek Project ”) could support a high productivity underground roomand-pillar mining operation using continuous miners. Results of testing and evaluation of coal seam roof and floor strata are consistent with geotechnical qualities of adjacent underground mining operations, including those operated by Alliance Resource Partners LP (“ Alliance ”) (market capitalisation $US3.15 billion).

Based on 2013 data, nine out of the top ten most productive non-longwall underground coal mines in the US are based in the Illinois Basin. The average productivity (saleable coal production per man hour) of mines located in the Illinois Basin (4.3 tons per man hour) is more than double the average productivity of Southern and Central Appalachian mines, significantly higher than Northern Appalachian mines and compares favourably to the average productivity of coal mines located in the major coal basins of New South Wales and Queensland, Australia.

Highly Productive Geology
Favourable geology, established mining infrastructure including coal mining equipment and services industries and access to highly skilled population centres within the Illinois Basin, lends itself to some of the most productive underground mining in the US. Based on the 2012 average tons of saleable coal produced per man hour, the average productivity of mines from the Illinois Basin (4.3 tons per man hour, 2012) is more than double that of Southern (1.7tpmh) and Central (2.0tpmh) Appalachia and significantly higher than Northern Appalachia (3.1tpmh). In addition, average productivity of the Illinois Basin compares favourably to the average productivity of the major coal basins of New South Wales (3.8tpmh) and Queensland (3.9tpmh), Australia. Note, the average productivity for the Illinois Basin is mostly derived from underground room-and-pillar mines, whereas the productivities for all other basins are predominately underground longwall and surface mines.
The Buck Creek Project is proximal to some of the largest and highest margin thermal coal mines in the US. Based on 2013 data, nine out of the top ten most productive non-longwall underground coal mines in the US are based in the Illinois Basin. The River View mine which began production in 2009 and produced 9.3 million tons in 2013, is the largest non-longwall (e.g. room-and-pillar) mine and the second most productive in the US. In developing the Buck Creek Project, Paringa will seek to replicate the productivity of underground mines in the region.

Geotechnical Review
Previously announced results from the nine drill core holes completed and announced to the ASX on 5 December 2013, reaffirmed that the Western Kentucky No.9 (“ WK No.9 ”) coal seam within the Buck Creek Project to be a thick, flat, consistent, and laterally continuous coal seam. In addition, drill logs indicated the actual coal seam thickness for most of the drill holes to be greater than that modelled in the Company’s Coal Resource Estimate of 154 million tons (~140 million tons), announced to the ASX on 4 November 2013. The WK No. 9 coal seam is the third largest producer of thermal coal in the US and hosts some of the most highly productive and high margin underground coal mines in the country.
The strata of the WK No.9 seam within the Buck Creek property generally exhibit a regional northeastsouthwest strike, and a regional north-westward dip towards the centre of the Illinois Basin. The strata types surrounding the WK No.9 coal seam within the Buck Creek Project are shale, sandy shale, sandstone, limestone, black shale, and underclay.
The main roof of the WK No. 9 seam is described as intact and competent, generally consisting of thin black shale that is overlain by thick grey shale followed by sandstone. Occasionally the black shale is absent and the grey shale becomes the immediate roof rock. Testing of the immediate roof of the WK No.9 within the Buck Creek Project indicates a Coal Mine Roof Rating that is comparable to adjacent underground mines.
Floor strata of the WK No.9 seam within the Buck Creek Project are typically shale, sandy shale, or underclay. Immediate floor stability in the Illinois Basin is dependent upon the competency of the fireclay and other strata beneath the coal seam. The combination of overburden depth, moisture content, and the immediate floor stability are the controlling factors for pillar design as part of the room-and-pillar mining operation. Samples of the immediate floor were taken to determine the moisture content as a function of depth into the floor. The pillar dimensions are varied to find the minimum pillar dimensions required to obtain a 1.30 safety factor for the Vesic-Gadde equation. Testing and evaluation has also concluded that significant horizontal stresses are not expected to be an issue.
The results of the geotechnical study will be incorporated into the Company’s Scoping Study and are expected to confirm the low potential operating costs of the Buck Creek Project. The results of the Scoping Study are expected to be released during March 2014.

ABOUT THE BUCK CREEK PROJECT
The Buck Creek Project is located in the Western Kentucky region of the Illinois Coal Basin which is one of the most prolific coal producing regions in the USA. Paringa controls over 25,000 gross acres (~10,000 ha) of coal leases within an area of interest of approximately 72,000 acres (~28,000 ha).
The Buck Creek Project has a JORC Coal Resource Estimate of 154 million tons (~140 million tonnes) of high quality thermal coal with over 88% in the Measured & Indicated categories. The Buck Creek Project is one of the few remaining contiguous high quality thermal coal projects within the WK No.9 Seam that is not controlled by one of the major USA coal companies and offers one of the highest quality, highest heating value products in the Illinois Coal Basin.
The Buck Creek Project is located adjacent to the Green River which provides year round linkage to the Ohio and Mississippi rivers systems which feed domestic coal-fired power plants and coastal export coal terminals in the Gulf of Mexico.

APPENDIX 2 – JORC Table 1 Checklist of Assessment and Reporting Criteria
Section 1 Sampling Techniques and Data
| 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 downhole 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. |
> All nine holes were drilled using a combination of rotary and core drilling designed for seam delineation and the acquisition of coal and rock samples for quality and strength analyses. > Air rotary holes were used to drill to within approximately 25 feet from the estimated depth of the coal seam. > The holes were then cored for approximately 40 feet with the intention of obtaining a continuous sample of roof, seam, and floor material. > Once coring was completed all holes were geophysically logged using downhole density, gamma, and sonic tools. |
| 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.). |
> The drilling consisted of 6.625-inch diameter air rotary holes followed by approximately 40 feet of 3-inch diameter conventional core holes for the collection of the roof, seam, and floor samples. |
| 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. |
> Core recoveries were monitored and were generally good at greater than 95%. > Coal core samples used for quality analysis contained greater than 95% recovery. > Where available, core recovery thickness was reconciled with the thickness interpreted from geophysical logs. |
| 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. > The total length and percentage of the relevant intersections logged. |
> Cored samples were geologically logged by the driller and by an independent third party geologist. > All holes drilled were geophysically logged by an independent third party using downhole density, gamma, and sonic tools. |
