ABSTRACT

Organization of the Access database of the Kadiica copper deposit Eastern Macedonia represents the first attempt of this paper authors to synthesize geological exploration data of this ore bearing locality in one professional database available for the wider auditorium. Authors experience in organization of similar databases for other metal deposits such are Bucim, Borov Dol, Zletovo, Sasa etc., gave us an opportunity to construct quality Access database for the Kadiica deposit. This deposit is of porphyry type with particular development of cementation zone where secondary minerals dominate. The chalcocite and covellite as main ore minerals in the ore body (600 m long and 100 m thick) pointed out that we are in the upper parts (oxidation-secondary enrichment zone) of a system with very likely porphyry type mineralization associated with porphyries in the deeper part of the system. Our latest paper focuses on efforts we made to organize Microsoft Access database with the most representative data for this particular deposit in the Republic of Macedonia. At the very beginning, with the software package “Microsoft Access” we have organized database with information of the most important geological, metallogenic and economic features of the deposit. The database was adapted for simple and sophisticated querying of particular deposit features and allows edition of reports and a geographic display of the queried information. Major data that completed database for the Kadiica deposit are: the deposit is at the prospect and detailed geological study with copper potentials, the Kadiica deposit is of combined type porphyry copper type complemented by secondary Cu sulphide (cementation) morphology, mineralization/rocks part of the database showed the mineralization age (relative 13.4-15.9 Ma; absolute 15 Ma) and host rock age (relative 28.4 - 23.03 Ma; absolute 26 Ma, K/Ar method) with main host lithology consisting of dacite, andesite, dacite–andesite breccia and their varieties, economic parameters were dominated by the fact that of proved mineral reserves of 69 Mt (as of 2013 and copper concentration of 0.21% Cu) as well as measured mineral reserves of 90 Mt (as of 2010 and copper concentration of 0.22 % Cu), also on the comments section we stressed out that its metallogeny is related to Tertiary calk-alkaline magmatism (predominantly Oligo-Pliocene) where mineralization is in dacite comlex suite while ore bodies are mainly secondary enrichment blankets.

Keywords: Kadiica copper porphyry deposit, Access database, reserves, economy.
