Limestone has been exploited at the Ostreš Quarry since 2008. The deposit is located in Stepanje, which is about 5 km from the municipality of Lajkovac. Near the quarry there is a connection for the highway “Milos Veliki”, which enables good transport communication and placement of products on a wide market.
The production of limestone aggregates is performed using two stationary crushing plants manufactured by Nace. The final products of this plant are fractionated aggregates for concrete and asphalt, tampons for the production of bearing layers for road construction, crushed stone, separated crushed stone and demined stone aggregates.
Production is organized in two shifts, 16 hours a day, 6 days a week.
The daily production capacity is about 3000 tons.
The annual production of all kinds of materials is about 600,000 tons.
Certified reserves for the existing exploitation field amount to about 6,000,000 tons.
