Seven un de vel oped sed i ment-hosted stratiform Cu-Ag de pos its con sti tute a fu ture re source base of cop per and sil ver ores in the Fore-Sudetic Monocline in SW Po land. Among these, four have only re cently been dis cov ered and doc u mented: Nowa Sól, Sulmierzyce North, Mozów (form ing a part of the North ern Cop per Belt) and ¯ary. The three re main ing de pos its -Bytom Odrzañski, G³ogów and Retków -sur round the cur rently mined New Cop per Dis trict to the north-west, north and north-east. Pol ish Cu-Ag de pos its are polymetallic: cop per, sil ver, lead, nickel as well as sub or di nate rhe nium and gold are cur rently ex tracted. How ever, they show high re port ing of other by-prod uct met als, such as co balt, mo lyb de num, va na dium, zinc and rare earth el e ments. Unit ore val ues ex pressed in US dol lars per met ric ton of ore have been cal cu lated for de pos its in the North ern Cop per Belt to com pare them with other un de vel oped and mined Pol ish sed i ment-hosted stratiform Cu-Ag de pos its. The cal cu lated unit ore val ues for the de pos its stud ied are pri mar ily in flu enced by cop per, with a sig nif i cant con tri bu tion (up to 29%) from sil ver. In terms of base met als other than cop per, their con tri bu tion to the unit ore val ues is here rel a tively low, ac count ing for only 1-11% of the to tal value. The pro por tions of sil ver and lead in the unit ore value show a trend: they tend to be lower in the vicin ity of ox i dized fields and grad u ally in crease with dis tance from these ox i dized ar eas. The share of nickel in the unit ore value, on the other hand, is not in flu enced by dis tance from the ox i dized fields. In stead, it is de pend ent on fac tors such as the thick ness and or ganic con tent of the shale ore, which af fect the ac cu mu la tion of non-fer rous, re dox-sen si tive by-prod uct met als, in clud ing nickel. Fur ther more, we pro vide a com par a tive anal y sis of the to tal unit ore value among Pol ish sed iment-hosted stratiform Cu-Ag de pos its. Par tic u lar em pha sis is placed on the de pos its that con sti tute the fu ture re source base of cop per and sil ver ores in south west Po land. A mar ket per spec tive is drawn to high light the in flu ence of metal price fluc tu a tions on the unit ore val ues of the var i ous de pos its. By ex am in ing the dy namic na ture of metal prices, the study of fers in sights into how changes in mar ket con di tions can im pact the eco nomic vi a bil ity of de pos its lo cated in dif fer ent parts of the Fore-Sudetic Monocline. The de pos its that con sti tute the fu ture re source base of cop per and sil ver in Po land show re markably high cop per and sil ver grades, re sult ing in sig nif i cantly higher unit ore val ues com pared to other world-class de pos its of dif fer ent types such as por phyry, epi ther mal, and IOCG (iron ox ide cop per gold) de pos its.

The Pol ish Ba sin is lo cated be tween the Pre cam brian East-Eu ro pean Plat form and the Cadomian Bo he mian and Ma³opolska mas sifs. The base ment of this Perm ian-Me so zoic ba sin com prises mainly Variscides and epi-Cal edo nian Paleo zoic rocks. In the prox i mal (NE) part of the ba sin, the Mid-Pol ish Trough is dis tin guished. In the dis tal (SW) part, the thickness of the Perm ian-Me so zoic suc ces sion is much smaller than in the Pol ish Trough. Palaeorift zones were ac tive from the Perm ian to the end of the Ju ras sic in the dis tal part of this ba sin. The Kupferschiefer min eral sys tem in di cates a palaeorift zone and smaller hot spots as sources of sup ply of met al lif er ous brines. The rel a tively small thick ness of the Rotliegend sand stones and their good per me abil ity and po ros ity prop er ties cre ated very fa vour able routes for the mi gra tion of metal-bear ing brines. The en tire Kupferschiefer polymetallic res er voir is re gion ally sealed by an hyd rites and salts of the Werra cyclothem. This was in clined con stantly from Perm ian times on wards to the north, fa vour ing the mi gra tion of polymetallic brines from rift zones to geo chem i cal res er voir traps. Min eral sys tem anal y sis of the polymetallic Kupferschiefer de pos its shows that the geotectonic set ting of this zone re lates only to the dis tal part of the Pol ish asym met ric rift ba sin. Key words: geotectonics, min eral sys tem con cept, con ti nen tal rift sys tem, Kupferschiefer, polymetallic de pos its, Pol ish Ba sin.
