Abstract

Organization of the Access database of the Northeastern (NE) part of the Central Part Ore body within Bučim deposit, North 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 interested parties. Ours experience in organization of similar databases for other metal deposits such are Zletovo, Borov Dol, Kadiica, Sasa etc., gave us the necessary knowledge and experience to construct quality Access database for the NE part of the Central Part Ore body within Bučim deposit. The Bučim has been classified as porphyry mineralization (0.3 % Cu, 0.3 – 0.5 ppm Au), which is spatially and temporarily associated with Tertiary subvolcanic intrusions of latitic and latitic- andesitic composition. The intrusions occurred during Oligo-Miocene time (24 to 27 Ma), a period of intensive tectono- magmatic and ore-forming processes. The whole array of major ore (hypogen) minerals was identified up to date: chalcopyrite, pyrite, magnetite, haematite, cubanite, valleriite, native Au and bornite, while sporadically occur chalcocite, covellite, tenorite, native Cu, malachite, azurite, calaverite, krennerite, electrum, petzite and bis- muth±selenium minerals (bismuthinite, galenobismutite,
krupkaite, friedrichite, emplectite, cosalite, laitakarite and na- tive bismuth). This paper focuses on efforts we made to organize Microsoft Access database with the most representative data for this particular deposit in the Republic North 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 NE part of the Central Part Ore body within Bučim deposit are: the deposit belongs to the famous Damjan–Bučim–Borov Dol ore district, it is at the industrial production stage under exploitation
concession of the Solway company with proved reserves of 12.3 Mt of copper and gold with 0.229% Cu and 0.232 g/t Au, mineraliza- tion/rocks part of the database showed the mineralization age (relative 16.4 – 13.6 Ma; absolute 16 Ma) and host rock age (relative 28.4 – 23.03 Ma; absolute 27
Ma, K/Ar method) with main host lithology consisting of gneiss, andesite and latite, economic parameters were dominated by the fact that of proved mineral reserves of 12.3 Mt (as of 2020 and combined copper and gold metal potential of 28 219 t Cu and 2 860 kg Au), also on the comments section we stressed out that its metallogeny is related to Tertiary calk-alkaline magmatism (predominantly Oligocene) where mineralization is in gneiss, andesite and latite complex while ore bodies are of disseminated character.
