Rock forming minerals were represented by plagioclase, K-feldspars, biotite and amphiboles. Beside their complex formulas those minerals have shown quite uniform compositions. Amphiboles were determined as hornblende, biotites were characterized by increased Fe and Ti and decreased Mg concentrations, pla- gioclases were determined as sanidine while K-feldspars were represented by albites and oligoclases. We have shown that the chalcopyrite composition is highly pure without any significant presence of Ni, Co, As and Sb (<0.01%). Py- rite analyses have shown that there are increased arsenic concentrations of 0.15 ÷ 0.22 % As, such concentrations of arsenic are indicative, but are very characteristic for low temperature pyrites from porphyry copper deposits. Beside the arsenic in pyrites, there were determined increased Ni concentrations 0.45 ÷ 1.42 % Ni, while Co and Sb remain below 0.01%. Key words: Buchim porphyry copper deposit; major minerals; composition INTRODUCTION First written records of the geological setting performed by Janković et al. (1980), Ivanov date from the turn of the 20th century (Cvijić, (1982), Čifliganec (1982, 1987, 1993), Palinkaš et 1906). This deposit has been explored in late 1930, al. (2008), Serafimovski (1990), Serafimovski et early 1940 and even during the Second World al. (1993, 1996, 2001, 2006), Serafimovski and War. The most extensive ones were in the period Čifliganec (1996), Strasimirov et al. (1996) and 1955–1976, followed by extensive diamond core others. This study was initiated by the idea to de- drillings and exploration mining drifts. Such broad termine the exact compositions of the major ore exploration programme have resulted with a start (chalcopyrite and pyrite) and silicate (plagioclase, mine of mine production in 1979. Since then the muscovite, biotite etc.) minerals from the ore body annual mine production rate used to be 3.8 Mt of Central Part. Findings from this study were put in ore processed in the concentration plant in Buchim, service of enhancing the ore milling and concentra- except during the short production break at the be- tion process. ginning of this century.
