(MENAFN - ProactiveInvestors - Australia) Prairie Downs Metals (ASX:PDZ) is estimating an initial exploration target of 1.1-1.3 billion tonnes of coal at its Lublin thermal coal project in Poland.
The review of Prarie Downs's historical and drilling data was done by UK-based Wardell Armstrong International, which included over 200 holes in and around the company's high-grade coal exploration concessions.
The review indicated that in-situ coal quantities range from 5,888 kilo calorie per kilograms to 6,894 kcal/kg with Ash content ranging from 8.4% to 18.2% on a Gross Air Dried basis.
The Lublin Coal Basin is in an established coal province where coal mining has taken place since 1982 and the region has extensive infrastructure including power and rail.
The independent experts report was prepared after visits to the coal concessions as well as confirming the validity of historical documents.
The historical data was sourced from state geological institutes, which showed that drilling in the area had taken place as early as 1965.
A total of 205 boreholes were reviewed with 117 of them in the Lublin coal basin. Drilling was done over a 1 to 1.5 kilometre grid with the boreholes returning 200,000 metres of coring.
Initial geological review shows that the carboniferous strata of the project are about 700 metres below surface, with proven seams at depths of between 1000 and 1300 metres.
And even though the Polish government has since reduced the minimum thickness of coal seam that can be classed as "in balance reserves" to 0.6 metres from 1.0 metres, Prairie Downs has used the earlier metric as the cut-off for the preparation of the exploration target.
The company is conducting geological modeling of the coal seams and is expected to delineate an initial coal resource estimate on the Lublin Coal project by the end of March quarter next year.
