To Whom It May Concern,

My company has provided contract project management services to Orica Mongolia LLC for the mobilisation of bulk explosives manufacture and delivery capability at the Oyu Tolgoi mine site.

I have served as Project Director for this project which involved the sourcing, delivery, installation and commissioning of equipment and facilities for the production and delivery of open pit and underground explosive products.

This project presented many challenges, particularly in sourcing materials and equipment, and in responding quickly to changing developments through the implementation program.

Murray Mining Services was initially used to provide some engineering fabrication services but grew to become our primary installation contractor, while also detailing and fabricating a number of more complex items of equipment that were added to the original scope.

Murrays have demonstrated great flexibility, resourcefulness and customer focus in supporting our project. Their involvement in the project grew significantly through the course of the project because of the value they were able to bring to the project. Their knowledge of the supply chain base and skills base in Mongolia, and of systems and resources on site, was invaluable to the project.

Murrays would certainly be my preferred supplier for project support on any future projects in Mongolia. I would be pleased to discuss any specific elements of their service and performance and can be contacted for further comment if desired.

Yours Faithfully
