Engineering company Downer has had its blasting services contracts in the mining sector extended for $230 million.

Coal miners Yancoal and Sojitz and gold producer Saracen extended its contracts with Downer Blasting Services (DBS) by another three years.

DBS has been working with Yancoal since 2006 and operates at Yancoal’s Moolarben, Ashton and Yarrabee mines, as well as the Duralie coal mine in NSW.

The contracts mean DBS will continue to work on Sojitz’s Minerva mine in the Bowen Basin, as well as Saracen’s Carosue Dam gold mine in Western Australia.

“This is a positive reflection on both the strength of our relationships with our customers and the quality of our service delivery,” Downer chief executive Grant Fenn said in a statement on Wednesday.

At 1147 (AEST) on Wednesday, Downer EDI Limited was down one cent to $3.83.
