New borehole data (from boreholes drilled after 2014) and reinterpretation of historical well logs enabled to update the acreage and reserve potential of Upper Permian (Zechstein) stratiform potash-bearing deposits in SW Poland (Fore-Sudetic area). These deposits, referred to as the Older Potash (K2) and the Younger Potash (K3), are included in the Stassfurt (Z2) and Leine (Z3) cyclothems. Within the present-day extent of both units, several prospective areas with the maximum depth to the potash seam of 2 km and its thickness over 2 m have been contoured. Foreach such area, predicted reserves of potash rock have been calculated (using such parameters as the area, average potash seam thickness, and specific weight of potash rock assumed at 2.1 Mg/m3). 7prospective areas (defined by 98 wells) of the Older Potash (K2) deposits have the reserves estimated at 3. 2 bln Mg and a total surface area of 454 km2. 6 areas (contoured by 23 wells) of the Younger Potash (K3) deposits characterize rocks of predicted reserves of 288.8mln Mg and a total surface area over 60 km2. Therefore, the area of SW Poland offers a relatively high resource potential for potash salts and a more detailed geological insight (and possible future exploitation) of 13 prospective areas with total predicted reserves of 3.53 bln Mg and a total surface area of up to 514 km2. Preliminary calculation of possible amounts of K2O in these reserves (assuming a low average K2O content at 1%) suggests 35.32mln Mg of potassium oxide. Because the potash-bearing seams in the study area are composed mainly of chloride K-Mg minerals such as sylvine (KCl) and carnallite (KClMg · Cl2 · 6H2O) easily dissolved in water, these seams are favourable for relatively cheap exploitation by underground leaching.

Fulfilling the role of the state geological survey (SGS), the PGI-NRI collects and processes information on the documented raw materials deposits, mining areas, and mining counties. The information sources include geological documentations of raw materials deposits and documents of mining areas and mining counties sent to the PGI-NRI by the concession authorities. The information is made available for wide public through the web services and applications. The data is available mainly on the website of the System of management and protection of mineral resources in Poland MIDAS. The system is the base for preparing the annual publication “The balance of mineral resources deposits in Poland”. Particularly noteworthy is the spatial information published up to date in the ready-map compositions (MIDAS map compositions, Geology map portal, GeoLOG mobile application), by the web services (WMS, WFS) and in the vector form in the popular shape file format. The article presents also the possibilities of further using, processing and analyzing of data. Moreover, the importance of such data for the implementation of public administration tasks, i.e. in the land-use planning process, raw materials policy on the country level, and as the support for other decision-making processes, is also discussed. The article also stresses the importance of the information resource as a valuable data source for investors, higher educational institutions, or scientific and research institutes.
