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 paper presents geological, ore-mineralogical and economic characteristics of the goldfields in the Western USA (California and Yukon) and Australia (Bendigo-Ballart and Kalgoorlie regions). Moreover, common geological features of these areas, which were the place of modern Gold Rushes from the second half of 19th c. to the beginning of 20th c. are also described. Thanks to discovery of gold, these inhabited areas became the land of promise for millions of people and gold production contributed to economy of the fast growing nations. The first period of Gold Rushes began in California (USA) and Bendigo-Ballart region in Victoria (Australia) in 1848 and 1851, respectively. Placer gold was discovered first in Cenozoic alluvial sediments and subsequently in auriferous quartz lodes, which were the source of detrital gold. The detrital sediments appeared extremely rich in gold nuggets. The biggest nuggets, ca. 65.2 and 24.5 kg in weight, have been found in Bendigo and California, respectively. Placer gold production during the Gold Rush in California from 1848 to 1864 is estimated at ca. 1300 Mg Au. Since 1850, prospectors begun to discover numerous gold-bearing quartz veins (Mother Lode system) along the Sierra Nevada in California. These auriferous lodes gave over 1100 Mg of gold. In Bendigo-Ballart goldfields about 480 Mg of gold was extracted from placers and 260 Mg goldfrom from auriferous quartz veins in the years 1851–1861. The second period of modern Gold Rushes took place again in America (Yukon) in 1896 and in the Western Australia (Kalgoorlie) in 1893. In Yukon, gold was mainly extracted from Cenozoic river’s gravels (> 311 Mg) and in Kargoorlie—mainly from auriferous quartz-carbonate lodes. Some of goldfields with auriferous lodes discovered in 19th c. are still in production. Best example is here the Kargoorlie deposit that became recently the 3rd largest world producer of gold (> 1600 Mg Au). Gold production from lodes in California, Bendigo-Ballart and Kalgoorlie is roughly estimated at > 4000 Mg. Gold-bearing lodes formed as results of migration of fluids of various origin and gold precipitation in the upper crust within post-collisional tectonic settings. These lodes belong to orogenic type of gold deposits hosted by greenstone schist belts in metamorphic terranes of various age. Primary gold is bound mostly by auriferous sulphides—arsenopyrite and pyrite and as native gold which infills fractures in quartz and breccias. In California, Yukon and Victoria, rich placers were formed in the Cenozoic during exhumation of metamorphic terranes hosting auriferous gold lodes.

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:
Jerzy Kanasiewicz was born on May 9, 1934, in Lwów. In the years 1953-1958 he studied geology at the Mining Institute in Jekaterinburg (Russia - Ural Mts.). In 1958, he began to work in the Geological Insti¬tute in Warszawa, in the Department of Rare and Radio¬active Elements. In 1967, he defended his doctoral thesis titled: "Occurences of rhenium and selenium and some other accompanying elements in the Lower Zechstein cupri¬ferous series of the Fore-Sudetic Monocline". He took part in several scientific expeditions in Asia and Africa, as an expert. In Vietnam (1971), Jerzy Kanasiewicz evaluated industrial potential of the Nam Nam Xe rare earth deposits in the Lao Cai province. He also visited North Korea in 1975. In the years 1979-1981, he worked in India as an expert of the United Nations. He conducted exploration for gold, tin, lithium, niobium and tantalum pegmatite ores, together with Indian geologists. The investigations took place in the state of Madhya Pradesh. He also visited Malaysia at that time, where he had opportunity to acquaint with methods of identifications and documentation ofclastic tin ores of the global importance. In 1982, Jerzy Kanasiewicz visited Libya where was involved in exploration and evaluation of the uranium resources. In mid-1980s, he created an ambitious and innovative program of geochemical-mineralogical researches in the Sudetes and Fore-Sudetic Block. He died untimely in Warszawa on August 24, 1992.

Opis:
As part of the tasks performed by the Polish Geological Survey (Polish Geological Institute - National Research Institute), 260 prospective maps (MOP) at a scale of 1 : 200,000 have been developed in the period of 2013-2015. These maps were designed for metal ores (Cu-Ag, Zn-Pb, Mo-W, Ni, Sn, Au, Pt, Pd and Zn oxide ore - galmans) and chemical raw materials (rock and potash salts, gypsum, anhydrite and native sulphur), in relation to the assessment of raw materials resources and environmental restrictions and land use planning. The total surface of prospective teritories projected onto the surface area is ~15.25 thousand km2 for metal ores and ca. 52.5 thousand km2 for chemical raw materials. The estimated resources of predicted ore deposits (prognostic and prospective) are approx. 42.2 million Mg of Cu and 75 thousands Mg of Ag (12 prospective areas), ca. 20 million Mg of Zn-Pb ores (in 4 prospective areas), 32 million Mg of Ni ores of weathering type (10 prospective areas), from 9.4 to 21.5 Mg of Au encountered by orogenic vein and metasomatic deposits (7 prospective areas), and ca. 22 million Mg of Sn ores. The estimated prognostic and prospective resources of chemical raw materials (at a depth of not more than 2000 m) are: ca. 4.059 trillion Mg of rock salt (68 prospective areas) and ca. 3638.1 million Mg of potash (12 prospective areas), as well as ca. 575.6 billion Mg of gypsum and anhydrite, and 202 million Mg of native sulphur (prognostic resources). In the assessment of environmental conflicts and land use planning, 125 information data sheets developed environmental conditions for prospective areas (with the exception of rock salts, which are discussed in the regional aspect). Development of the designated prospective areas may be important in the future to ensure the availability of raw material safety, not only for Poland, but also for the European Union, thus contributing positively to economic growth and prosperity of local communities.
