Holcim plans to expand the Gabenchopf quarry in Villigen, Switzerland, to the west to yield around 12Mt of rock. The step is designed to maintain operations for the next 10 years at the company’s Siggenthal works.

The cement works has drawn upon Gabenchopf for its supply of limestone and marl since 1955. The raw materials are transported to the plant via a 3.7km-long conveyor belt. The current mining permit, which includes a comprehensive rehabilitation scheme, dates from 1998.

Initial discussions with representatives of public authorities, businesses and associations took place in autumn 2014. Detailed studies and land use planning will follow this and early next year. The quarrying application is expected to be submitted in autumn 2016.
