PRAIRIE (PDZ): Drilling Affirms Jan Karski as Semi-Soft Coking Coal Project

UNI - EN REPORT No5/2018



•Prairie’s use of modern exploration techniques continues to transform the Jan Karski Mine with latest drill results re-affirming the capability of the Project to produce high value ultra-low ash semi-soft coking coal, known as Type 34 coal in Poland

•Outstanding results from coke oven testing demonstrate superior coal quality specification compared to typical parameters of internationally traded semi-soft coking coals and domestic Type 34 coals, including an exceptionally high Coke Strength after Reaction which is a parameter highly prized by steelmakers

•Historically Poland’s Lublin Coal Basin has been associated with thermal coal production, however Prairie’s exploration program conducted according to international standards has demonstrated beyond doubt that the 391 coal seam at Jan Karski hosts a globally significant deposit of semi-soft / Type 34 coking coal

•Washplant flow sheet design conducted as part of the China Coal technical studies anticipates mine production will be up to 75% ultra-low ash semi-soft / Type 34 coking coal, with outstanding overall saleable coal yield of 82%

•Czech and Polish supply of semi-soft / Type 34 coking coal to the European steel industry has dramatically decreased over the last two years due to mine closures and declining production, with regional coke and steelmakers forced to replace the supply deficit with imports

•Benchmarking analysis of Jan Karski’s ultra-low ash product against semi-soft coking coal produced in the Czech Republic and from recently closed Polish mines demonstrates the potential of the Jan Karski Type 34 coal to replace these coals in the regional market

•The Company can now advance discussions with regional steelmakers and coke producers for future coking coal sales and offtake on the basis of selling ultra-low ash semi-soft / Type 34 coking coals from Jan Karski

•Drill results will be incorporated in China Coal’s technical studies for the Jan Karski Mine

Prairie Mining Limited (“Prairie” or “Company”) is pleased to announce 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.

These latest results will be incorporated into the non-JORC technical studies currently underway by Prairie’s strategic partner, China Coal.

Prairie’s CEO Ben Stoikovich commented: “Prairie’s modern exploration program has demonstrated that Jan Karski is a globally significant semi-soft / Type 34 coking coal project, whereas historically the Lublin Coal Basin has been associated with thermal coal production only. This presents an outstanding economic development opportunity for the Lublin region, and Chelm province in particular, to become a leading European supplier of coking coal to the steel industry. Our latest studies anticipate that up to 75% of saleable production will be semi-soft / Type 34 coking coal, which is a high value product with the current benchmark FOB Australia price at ~USD135/t. With such a high proportion of saleable product from Jan Karski anticipated to be high value semi-soft / Type 34 coking coal, project economics are likely to be significantly enhanced compared to the 2016 Pre-Feasibility Study results. Coal tested from the Kulik 1 borehole demonstrated exceptional coking parameters, including CSR of 54, swelling index of 7.0 and fluidity of 268. With the ongoing closure of coal mines in the Czech Republic and Poland that produce semi-soft / Type 34 coking coal, there is a growing regional market opportunity for Jan Karski ultra-low ash semi-soft / Type 34 coking coals. Independent analysis has indicated that due to the superior coal quality of Jan Karski semi-soft / Type 34 coking coal, we have the potential to achieve market pricing of some 10% above the standard international SSCC benchmarks.”
