Twenty-four rock trucks and dozens of other late-model heavy equipment items will be sold to the highest bidders-regardless of price-when Ritchie Bros Auctioneers conducts an unreserved mining equipment auction on September 18 at Yatala on the Gold Coast, just south of Brisbane, Australia.

Ritchie Bros will be selling equipment at the public auction for Downer EDI Mining, formerly Roche Mining, and more than 20 other owners.

So far, there are more than 430 items being sold on auction day, including late model motor scrapers, wheel loaders, hydraulic excavators, motor graders, crawler tractors and water trucks.

Ritchie Bros regional manager Simon Ross says: "We are very pleased to be selling such a high caliber, clean, well-maintained mining equipment package; it's a credit to Downer EDI Mining."

Downer EDI Mining is one of Australia's major providers of open-cut and underground mining and mine development services. It will sell more than 40 heavy earthmoving equipment items at the auction, including three 2005 and one 2003 Komatsu hydraulic excavators, four late-model Cat crawler tractors (two D10R and two D9R), 16 Cat 777D rock trucks, two 1994 Cat 775B 35,000 litre water trucks, five late-model wheel loaders and three late-model motor graders. The equipment was used in a recently completed mining project in Laos.

The unreserved public auction starts at 8am on Tuesday, September 18 at the permanent Ritchie Bros auction site on the Gold Coast.
