Expression of Interest

This scope of Services sets out the duties of the contractor for:

. Transport of product from the loading point by road along the Site Access Road and then public highways A87 and A1 to the delivery point in Adelaide;
. Loading and sampling of concentrate into the OZ Minerals provided shipping containers;
. Other Site and logistics services as set out in this schedule.

The main elements of the scope are:

. Pick up and load product at the loading point from the bulk stockpile into OZ Minerals supplied containers. Each container will require sampling, weighing on the loading operation. The equipment to load the containers is to be supplied by the contractor;
. Deliver the containers by road to the delivery point;
. Unload containers at the delivery point;
. Collection of empty, back-loaded containers at the delivery point and return them to the loading point by road to be reloaded with product;
. Management of container logistics with Carrapateena Operations;
. Stockpile movements of product from the filter discharge bunker to the concentrate storage pad if required, as directed by OZ Minerals.

The road haulage is a 365 day per year operation. The shipping containers are shared between OZ Minerals Carrapateena and OZ Minerals Prominent Hill, of which there are currently 1,400 units. The maximum load weight of the container for road freight on a public road is 25WMT, which must be strictly adhered to by the contractor. The process is required to deliver a consistent supply of product to the delivery point consistent with the Carrapateena Mine production plan. There is limited storage for product at the mine site for both bulk concentrate powder and storage of containers. To assist the contractor, the processing department will provide production planning guidance on a consistent basis as well as clear specifications of the storage and facilities provided for at the mine site.

Majority of works to be undertaken by 20T Franna, however, capability to undertake up to 100t lifts required.

This scope is for the supply and maintenance of surface mobile equipment serving the operations department of the Carrapateena project. This equipment is to be used in the minerals processing plant to ensure safe and efficient continued operation, however may be used in areas outside of this on occasion based on operational needs.

The equipment specified below is outlined for a sizing guidance only, and other equipment manufacturers may be substituted as a part of the proposal. However, the functionality of the machinery must meet the desired specification, unless otherwise agreed.
. Komatsu WA250 Front End Loader (FEL) or equivalent.
. Komatsu SK820-5 Skidsteer loader or equivalent.
. Excavator (40t) CAT336L or equivalent.

The scope of supply is dry hire as the equipment will be operated by OZ Minerals staff at the minerals processing facility (MPP). Minor maintenance (lube / grease addition, checks) can be completed by OZ Minerals staff. All major repairs and maintenance should be complete as a part of the scope of supply.

The scope includes maintenance required to ensure ongoing reliability of the equipment and any fair 'wear and tear' incurred in the course of equipment use. Major damage repairs should be charged to OZ Minerals at a market competitive rate.

If a small maintenance facility is required on site, this may be proposed by the vendor as a component of the scope of supply. The approval of a facility is at the discretion of OZ Minerals and the cost should be borne by the vendor, rolled into the scope of the supply.

OZ Minerals is seeking expressions of interest from organisations with demonstrated experience providing an integrated logistics solution for mining operations during the construction stage. Respondents must be able to demonstrate how they have added value to projects through the development and implementation of their solution.
