The Lahanos Copper and Zinc Mine are located within the village borders of Şahinyuva, 22 km south of the Espiye district in Giresun province.

After prospecting, exploration and feasibility studies were completed between 1988 and 1990 at our Lahanos Mine, ore, produced from trial mining, was enriched in our company's flotation plants in Tirebolu between 1990 and 1991. Upon commissioning the Lahanos concentration plant in 1992, ore enrichment operations have been carried out at this facility. In the middle of 1993, the Lahanos Mine had to suspend all of its activities due to the decline in metal prices. The Lahanos Copper Mine continued production, starting the second half of 1994 through 1997 but ceased operations at the end of 1997 until the end of 2005 for the same reason – metal prices. The preparatory work, started at the end of 2005, was completed in the first half of 2006, with production resuming in the second half of the year.

At this mine, complex ore are obtained by using underground concrete back-filled room and pillar method, and the selective copper concentrate is produced after being enriched at the flotation plant.

Produced copper concentrate is exported abroad.
