Plans for an extension to a quarry in Leicestershire that will safeguard 140 jobs have been approved by the county council.
Leicestershire County Council has voted to allow Aggregate Industries to expand Bardon Hill Quarry in Coalville.
The Bardon Hill site has 480 employees, including 340 administrative staff, and the firm spends more than £5m a year on local goods and services.
The quarry will mine 132 million tonnes of stone over the next 40 years.
Aggregate Industries spokesman Colin Parke said: "Bardon Hill already has a 150-year history as a quarry, and we are really delighted that its life will now be extended to 2050 and beyond, safeguarding the jobs of many local people and injecting significant funds into the local economy."
Conditions of the planning permission include screening of embankments, the use of conveyors to transport clay as opposed to dumper trucks and a visitor centre which will showcase the local wildlife and the area's biodiversity.
The company will also invest 5p for each tonne of mineral sold from the extension area into a fund for local communities and organisations.
