CVK Maden İşletmeleri San. and Tic. Inc. Kalkım Lead-Zinc Enterprise is located approximately 3.5 km from Kalkım town in Yenice district of Çanakkale province. It is located in the southeast and approximately 2 km east of Karaaydın village. There are underground mines, administrative buildings, flotation facility and waste pool in the licensed area with an area of 1,609.14 hectares. Run-of-mine ore produced in underground mines is processed in the flotation facility and turned into lead and zinc concentrate, and a significant part of it is exported.

In the license area in the Kalkım region, with the completion of the exploration activities in 2012, work was started to produce run-of-mine ore. In order to process the run-out ore produced, a flotation facility equipped with state-of-the-art equipment, fully automated, with a daily feeding capacity of 1,000 metric tons was established and a waste pool was built in 2012-2013.

500,000 metric tons of run-of-mine ore can be produced annually in the fully mechanized underground mines located in the license area in the Kalkım region, and 30,000 metric tons of lead, zinc, copper and silver concentrate can be produced annually from the run-of-mine ore processed in the flotation facility with an annual feeding capacity of 300,000 metric tons.

In order to support the production of run-of-mine ore that will feed the flotation facility in the Kalkım region, capacity-increasing works were carried out and new lead-zinc fields with operating licenses were taken over in the Çanakkale-Yenice and İzmir-Bayındır regions in 2017, and in 2019, a new lead-zinc field with an exploration license in the Balıkesir-İvrindi region was acquired from the MAPEG tender.
