Mine site, is within the administrative borders of Yenice county of Çanakkale Province. It is located at the north east of Yenice County. Distance to county Centrum is 15 KMs; distance to flotation plant is 90 KMs. The nearest residential area is Karaköy which is located in southern side and at a distance of 8 KMs.
1. GENERAL DEFINITION OF MINE SITE
Within the site field, usually trias aged units like Quartzite-Meta Arcosis, Meta Siltstone, Meta Diabas and Gabro, belonging to Karakaya formation and towards west, neogen aged dasitic igneous could be viewed.
There is hydrothermal type polymetalic (Pb, Cu, Zn, Au, and Ag) ore formation is available and shows ore formation in deposite type which is located between diabas. Ore formations in the East/West direction are more economic when compared to North-East/South-West direction ore formations. In the field there are two East/West direction deposit (fourth and fifth deposits) studies are held on those deposits. Deposit thicknesses are ranging from 1, 5 mt to 2 mt while they are qualified as two different deposits in means of ore content.
4th deposit is rich in copper and lead minerals, 5th deposit is rich in lead and zinc minerals.
2 – PROVEN AND POSSIBLE RESERVE
Values are given in the reserve table which dates back to 2007.
Proven reserve amount : 713.006 ton
Possible reserve amount : 210.469 ton
Total reserve amount : 923.475 ton

The grade is uniformly distributed between lower and upper elevations and with no significant changes in grade, in the 4th deposit, there’s a descension in the western direction.

5. Deposit ore 0, 99% 7, 67% 4, 40 %
4- INCREASED IN ORE RESERVE
With the drillings to the +100 elevation, there’s been a calculation of 923475 tons of visible + possible reserve. With drillings from +100 elevation to 0 elevation, and west of deposits 4–5, it is estimated that the reserve amount may increase.
5-MINERALS FORMING THE ORE
Copper Mineral : Chalcopyrite (Cu Fe S2)
Lead Mineral : Galenite (Pb S)
Zinc Mineral : Xfalerit (Zn S)
6. PRODUCTION VALUES
There’s been a production of 306.000 tons of ore since the beginning of the year 2001 to the end of year 2007. Production values of the last three years are given as follows.
