Opis:: Ten prospective areas have been delineated for nickel ores of weathered type (saprolitic Ni ores) in Poland. The Ni ores are hosted by serpentinite wastes developed on the Szklary, Braszowice–BrzeŸnica and Gogo³ów–Jordanów massifs in the Fore-Sudetic Block of Lower Silesia. In total the prospective areas cover ca. 43 km2. The prospective areas were recognized on the basis of current regulations which defined marginal parameters of a specific deposit and delineated its borders. Total prognostic and prospective Ni ore resources were calculated for ca. 32.5 million Mg (ca. 120 thousand Mg Ni metal). Among them five prospective areas with prognostic resources (ca. 22 million Mg of Ni ores, ca. 89.1 thousand Mg of Ni metal) and five with prospective resources (ca. 10.5 million Mg of Ni ores, ca. 32.1 thousand Mg of Ni metal) were recognized. Modern Ni prospecting and verification of current documented resources in the Szklary Ni deposits according to new criteria should increase Ni weathered-type ore resources in Poland. Besides, the development of proper hydrometallurgical processing of low-grade Ni-saprolitic- type ores is highly required.

Opis:: Seven prospective areas have been delineated for gold deposits of vein and metasomatic types in the Sudetes (Kłodzko–Złoty Stok, Southern Kaczawa Mountains and Rudawy Janowickie prospective areas), on the Fore-Sudetic Block (Wądroże Wielkie) and in the contact zone of the Małopolska Block with the Upper Silesia Block (Dolina Będkowska, Pilica and Mysłów prospective areas). In total they are covering ca. 285.5 km2, (ca.252 km2 in the Sudetes and ca. 22 km2 on the Fore-Sudetic Block). The prospective areas were recognized on the basis of current regulations, which defined marginal parameters of specific deposit and delineated its borders together with application of adequate quantitative Au deposit models supported by ore parameters from the old mining records. Total predicted/estimated gold resources (prognostic + prospective resources),which are depending on the applied parameters, are from ca. 9.4 Mg (for n = 16 ore bodies) to 21.5 Mg (for n = 64 o.b.). The auriferous ores of the vein and metasomatic types (blind bodies) are associated with the metamorphosed volcanic-sedimentary Paleozoic formation in Lower Silesia and with contact-metasomatic zones around Variscan granitoid intrusions in southern Poland. The greatest estimated Au resources were recognized in the following areas: K³odzko–Z³oty Stok – ca. 6.3 Mg Au (for n = 7 o.b. – skarns, veins and beresites), Southern Kaczawa Mountains – ca. 4.8 Mg Au (for n = 15 o.b.) and Rudawy Janowickie – ca. 4.5 Mg Au (for n = 20 o.b. of vein and/or skarn types). In the contact zone of the Małopolska Block with the Upper Silesia Block the prospective areas are associated with the marginal zones (epithermal Au veins) around the granitoid/porphyry-related mineralization of the Mo-Cu-W type. The limited ore prospecting causes difficulties in estimation of Au resources in that area. The available data has allowed for a rough estimation of Au resources from ca. 1 to 3.5 Mg (for n = 5–21 o.b.). In most of the recognized Au prospective areas, auriferous mineralization is in paragenetic association with refractory gold sulfides and only sporadically appears as native gold or electrum mineralization (mainly in quartz veins). A new stage of gold prospection is highly recommended especially within the abandoned gold mining areas in the Sudetes. An application of modern geophysics (VLF and IP) followed by shallow drillings should bring new discoveries of gold deposits. In the report, environmental and spatial conflicts have also been pointed out within the specific gold prospective areas in relation to the presence of National Parks, NATURE 2000 areas, underground water reservoirs, etc.

Opis:: The fast-growing discipline in the field of geothermal research is the prospecting for geological structures useful for HDR (Hot Dry Rock) or EGS (Enhanced Geothermal Systems) technologies. In Poland, an interesting area for such research is the Sudetes, particularly the Karkonosze Mts. pluton and Fore-Sudetic Block. The article presents issues of scientific projects prepared in the Division of Renewable Energy of Mineral and Energy Economy Research, Institute of the Polish Academy of Sciences in Kraków, related to the recognition of geothermal conditions of the Sudetic region. On the background of global research, these projects demonstrate an innovative character mainly by targeting research on the analysis of tectonics and volcanism of the Sudetes as important factors of the presence of local positive thermal anomalies. Implementation of the afore-mentioned projects would create the possibility of extending still modest knowledge of the deep geological structure of the Sudetic area.
