Prairie Mining Limited announced the results of preliminary coal quality analysis from a borehole drilled at the company's Debiensko Hard Coking Coal Project during 2015/2016 by the previous owners. Prairie's preliminary review of the Debiensko deposit indicates that a range of premium hard coking coals can be produced from the project that will be in high demand from European steelmakers. Two premium hard coking coal specifications have been delineated at Debiensko, namely Medium volatile matter hard coking coal and Low volatile matter hard coking coal. The borehole was fully cored to 30 m below seam 407/4. All core was subject to detailed logging and core photography. Seam thicknesses and depths have been confirmed by a suite of geophysical logs while coal seams were analysed by accredited laboratories in Poland. Both Debiensko's Mid-vol and Low-vol HCC lie within the range of premium hard coking coals produced globally. Indications are that the Mid-vol HCC at Debiensko is present between 850 m to 1,000 m from surface and the Low-vol HCC is present 1,000 m to 1,300 m below surface that is at depths similar to adjacent operating mines owned by Jastrzebska Spólka Weglowa S.A. - the large coking coal producer in Europe. The quality of Mid-vol HCC from Debienkso compares favourably with the Australian Goonyella hard coking coal brand, and with medium volatile coals produced in Poland by JSW. This coal features good rheological properties and coke yield, with reasonably low sulphur levels. Prairie's assessment is that Mid-vol HCC from the Debiensko project would receive premium pricing in European and international markets. Debiensko's Low-vol HCC is similar to other internationally traded low volatile matter hard coking coals, including brands such as Peak Downs (BHP Billiton Mitsubishi Alliance - BMA) and Hail Creek (Rio Tinto) produced in Australia. Whilst the Coke Strength after Reaction (CSR) is anticipated to be slightly lower than these Australian coals, the quality of Debiensko Low-vol HCC is anticipated to be in-line with coal produced at JSW's Jas-Mos mine in Poland, which is used as a stabilizing and leaning component of nearly every coal blend for production of blast furnace coke in the region.
