Prairie Mining Limited announced the results of enhanced coal quality analysis and test work from a recently completed borehole (Kulik 1) at its 100% owned Jan Karski Mine ("Jan Karski" or "Project"). The coking coal quality results are superior to the drill results announced in May 2017, and further confirm that Jan Karski is a globally significant semi-soft coking coal ("SSCC") /Type 34 coking coal deposit with the potential to produce a high value ultra-low ash SSCC with an exceptional CSR and a high 75% coking coal product split. Comparison of the latest coking coal quality results to other mines in Poland and the Czech Republic that have historically produced SSCC or Type 34 coking coal show the great potential Jan Karski has to meet European market demand for Type 34 semi-soft coking coal as production from other Czech and Polish mines continues to diminish over the coming years. Prairie has now completed drilling the Kulik 1 borehole at Jan Karski which was a large diameter borehole enabling sufficient quantities of coal from the 391 seam to be collected to meet the requirements for physical coke testing, specifically confirmation of Coke Strength after Reaction ("CSR") and extended coal washability test work. Coke testing was conducted at Centralne Laboratorium Pomiarowo-Badawcze Sp. z o.o. ("CLPB") laboratories in Poland which is controlled by Jastrzbska Spólka Wglowa ("JSW") and is internationally accredited as a commercial coal and coke testing laboratory. Washability and other basic coal quality analyses were conducted in the UK. CSR analysis is considered vital in testing for a coal's coking properties and is important to steelmakers as it is an indicator of the performance /strength of the coke produced from the coal. Washability analysis from the Kulik 1 borehole and previous boreholes drilled by Prairie across Jan Karski has demonstrated that due to the low inherent ash and excellent washability characteristics of the 391 seam, Jan Karski SSCC is unique with ash product levels of 3.45% or less (air dried) and far superior to typical ash levels for major coking coal brands (both hard and soft) traded internationally and produced domestically in Europe. There is a range of ash specifications for semi-soft coking coals. Coal from the Kulik 1 borehole had ash of 3.45% at a float RD of 1.4, again demonstrating that Jan Karski SSCC is an ultra-low ash product compared to other SSCCs. Low ash provides a number of technical benefits including improved coke strength and caking properties, and reduced fuel rate in the blast furnace. The ultra-low ash content increases the coal's value-in-use to steel and coke makers, making the product highly saleable in both the domestic European and international markets. One of the key outcomes of utilising ultra-low ash coking coal to produce low ash coke ash is the resulting decreased fuel rate. This has a key environmental benefit for steel makers as it reduces CO2 emissions per tonne of hot metal produced. Prairie's analysis predicts increasing global demand for ultra-low ash coking coal for blending with hard coking coal ("HCC"), due to a continuing trend of rising average ash levels in globally traded hard coking coals. Premium HCC resources with low ash are becoming increasingly scarce, forcing consumers to make concessions on HCC ash levels. Ultra-low ash coking coals for blending are becoming increasingly sought after by consumers seeking to "blend-down" the ash levels in their coke blends. This is a particular advantage for European steelmakers where EU regulations focus on reduced CO2 emissions and compliance with other EU emissions directives. The trend of ever more stringent emissions standards for steelmakers imposed by the EU indicates a positive future for marketability of Jan Karski ultra- low ash semi-soft /Type 34 coking coal. Other Jan Karski ultra-low ash SSCC quality positives are its high vitrinite content, high-range FSI (7.0), and fluidity of 268. The volatile matter is in the range typical for Australian traded SSCCs. Declining production of Czech and Polish semi-soft /Type 34 coking coal has resulted in steel makers becoming more aware of the importance of security of supply of the raw material. Over the last 12 months, lack of delivery of semi-soft /Type 34 coking coal has forced some Central European steel makers to introduce urgent measures including changes in the coking charge mix and increased imports, thus generating additional costs and disturbing normal production.
