Positive coal quality analysis results for Aspire’s Jan Karski mine

Prairie Mining Ltd has announced the results of enhanced coal quality analysis and test work from a recently completed borehole (Cycow 9) at the Jan Karski mine.

Key results from the expanded coke oven and washability test work indicate the potential to produce a high value ultra-low ash SSCC with a high CSR, with a high 75% product yield. Preliminary analysis by independent consultants indicates that the Jan Karski ultra-low ash SSCC could achieve a 10% premium to international SSCC benchmark prices, due to several superior qualities.

Prairie’s CEO Ben Stoikovich commented: “The expanded washability and coking analysis from the recently drilled Cycow 9 borehole has confirmed that a high-value ultra-low ash SCCC can be produced from Jan Karski, at a product yield of 75%. This transforms Jan Karski into a predominantly coking coal project with superior semi-soft coking qualities that have potential to achieve market pricing of some 10% above the standard international SSCC benchmarks. With the expected closure of coal mines in the Czech Republic that produce SSCC by 2022, there is a growing regional market opportunity for Jan Karski ultra-low ash SSCC coals.”

According to a company news release, washability results demonstrate the ability to produce ultra-low ash (<3%) semi soft coking coals that are in high demand from global stealmakers due to the considerable commercial advantages of enhanced “value in use” and lower CO2 emissions.

Coke oven tests demonstrated exceptional results with Coke Strength after Reaction (CSR) of 51.5, exceeding typical CSR parameters of internationally traded semi soft coking coals.

Preliminary wash plant flowsheet redesign anticipates a significantly upgraded product split of 75% ultra-low ash semi-soft coking coal, and is not expected to result in a reduction of overall saleable coal product yields, or material project cost increases.
