Reference information

Comments Ikiztepe (Ikiztepe Hill) is the site of several copper-molybdenum-gold skarn-porphyry-type mineral occurrences. Cu-Mo-W mineralization is associated with granodioritic to quartz monzonitic granitoids (Ohta and others, 1988). Mo mineralization is conspicuous (Yigit, 2009). Skarn mineralization occurs where the granitoids encountered calcic rocks such as dolomitic limestone (Taner and Çagatay, 1983). Mineral suites consistent with skarn deposits (diopside, actinolite, biotite, garnet, titanite, tremolite) and those consistent with porphyry deposits (chalcocite, molybdenite, chalcopyrite) are present (Taner and Ça?atay, 1983). Tungsten mineralization occurs as scheelite and wolframite (Taner and Ça?atay, 1983). Ikiztepe is one of the most important ore deposits in the Thrace region because it has been worked for copper, molybdenum and tungsten (Taner and Ça?atay, 1983). From the 1970s to the early 1990s, exploration focused on part of the known skarn deposit at Ikiztepe where drilling delineated several mineralized areas (Slim, 2006). In 1978, Granges International Mining calculated a resource of 2.2 Mt at 1.17 percent Cu and 0.07 percent Mo in the skarn and 13.5 Mt at 0.52 percent Cu and 0.05 percent Mo of disseminated porphyry style mineralization (News Blaze, 2007).
