SC34 PERFORMANCE WARRANTY

SC34.1 General Conditions of Warranty

The Process Performance Warranty (as detailed in the technical specification) is valid provided the following general conditions are met:

	•		That the equipment and machinery to be furnished by the Supplier shall be erected under the advice of Supplier personnel. That all equipment, machinery, and components not furnished by Supplier are properly sized, installed, and satisfactorily operating.
	•		That the start-up, preliminary operational period, and acceptance tests take place under the advice of Supplier personnel.
	•		That the constituents of the materials to be ground are within the specification limits and/or do not adversely affect performance and operation.
	•		That the mill system is properly controlled and operated in accordance with Supplier’s recommendations and that the Purchaser shall maintain and permit Supplier access to comprehensive daily records of performance data (including power draw, pulp density, feed particle size distribution and ore SG).

Page 11 of 13

Incorporated in these records shall be sampling and data gathering according to Supplier recommendations. Such records shall be maintained from start-up of the system to such a time as Process Performance/Power Draw Warranties are deemed to have been met.

That all power draw figures given by Supplier are subject to a measuring tolerance of 3%.

SC34.2 Acceptance Tests

After final shipment, there will be a preliminary start-up period not to exceed twelve (12) months, during which the Purchaser will erect the equipment and run-in.

Purchaser shall notify Supplier of date that equipment is ready for testing; however, if through no fault of Supplier, the performance tests are not commenced within eighteen (18) months from the final shipment, Supplier shall be deemed to have satisfied the Performance Warranty and will be discharged from all further obligations under this warranty regardless of whether or not the tests are conducted.

The acceptance tests will be conducted during a twenty-four (24) hour period of substantially continuous operation. Any interruptions during this period not exceeding eight (8) hours in total, which are not due to the fault of Supplier, shall be counted toward the twenty-four hours and the average output will be computed on number of hours of actual operation.

If, during the acceptance tests, the guaranteed figures mentioned herein are obtained, the equipment and machinery (all xxxxx) furnished by Supplier shall be accepted as meeting this Warranty.

If, during the acceptance tests, the guaranteed figures mentioned herein are not obtained due to reasons attributable to Supplier, an additional six (6) month term shall be granted to Supplier. During this term, Supplier shall have access and opportunity to correct possible defects of the equipment and machinery supplied by Supplier in order to meet the guaranteed figures. After such corrections, the Process Performance acceptance tests will be repeated, subject to the same standards and procedures as previously set forth.

The Purchaser shall make available free of charge to Supplier, qualified personnel to properly operate the equipment and machinery. The Purchaser shall also furnish all raw materials, consumables, equipment, and utilities required to conduct the acceptance test at no charge to Supplier.

SC34.3 Liquidated Damages

If the power draw figures, taking into account the % tolerance, are not attained (after the period of rectification and retest) due to reasons for which Supplier is responsible, the Purchaser is entitled to claim the following sums as liquidated damages. Payment by Supplier of such liquidated damages will release Supplier from any future or further claims or liability.

For each full unit of kW less than the warranted power draw, subject to the tolerance, Supplier agrees to pay AUD per unit up to a maximum total amount of AUD. These Liquidated Damages shall apply separately to each mill.

Purchaser’s sole and exclusive remedy for failure by Supplier to attain the guaranteed figures shall be payment by Supplier to Purchaser of the liquidated damages as set forth above. Supplier’s responsibility for failure to attain the guaranteed figures shall in no case exceed the liabilities stated in this guarantee. The application of liquidated damages for the guaranteed figures shall not serve to decrease the Supplier’s liability as detailed in GC 29 and item 37 of Annexure Part A to the General Conditions.

Except as stated in this process performance/power draw warranty and except as to title, there are no guarantees or warranties of Merchantability, Fitness for Purpose, performance or otherwise, express, implied

Page 12 of 13

or statutory, and Supplier shall have no liability for consequential, incidental or other damages, howsoever caused.

AGMA         American Gear Suppliers Association

ANSI           American National Standards Institute

ASME         American Society of Mechanical Engineers

AWS           American Welding Society

ASTM         American Society of Testing and Materials

Work under this specification shall be performed in accordance with the above referenced codes and standards. In instances where national codes do not exist, materials and workmanship shall follow the prevailing manufacturing industry standards for semi-autogenous grinding xxxxx.

4.0 OPERATING AND DESIGN CONDITIONS

4.1 General

The equipment will be installed outdoors and shall be designed to operate 24 hours per day, 7 days per week, 365 days per year. The Supplier shall identify in his proposal all special requirements for outdoor operation in a tropical climate.

The grinding system will consist of one SAG mill followed by one Ball mill. The SAG mill will operate in closed circuit with an integral trommel system. Trommel oversize will discharge to the pebble crusher feed conveyor. Trommel undersize will report by gravity to a Ball mill cyclone feed

Page 3 of 6

sump. The Ball mill will operate in closed circuit with a cluster of cyclone classifiers. Provision will be made for a portion of cyclone underflow to be recycled to the SAG mill feed if required.

The ultimate capacity of the grinding system is 600 dry tph metric, which is the new feed rate to the SAG mill. This design capacity includes a 92% mechanical availability allowance.

The detail design and construction requirements for the SAG mill components and gearing are specified in Appendix B and Appendix C.

4.2 Performance

The SAG mill receives primary crusher discharge as follows:

Ore specific gravity			2.78
Ore dry bulk density, t/m3			1.4
Ore feed rate, dry t/h			600
Feed size, 80% passing, mm			150
Feed size, maximum, mm			400
Product size, 80% passing, microns (trommel undersize)			1,200
Slurry density mill discharge, % solids			65

The mill is estimated to be capable of drawing the 5500 kW at the pinion at 75% of critical speed with a 12 to 15% or greater ball charge and a total charge of 28%.

The mill should be able to operate at the design conditions (10% ball charge, 28% total charge) in the speed range of 50% to 75% of critical speed over the full wear life of the liners. For the 75% to 85% speed range the mill should be able to operate at maximum power but possibly with reduced ball charge.

4.3 Performance Warranty

The SAG Mill is mechanically and structurally capable of drawing 5,500 kW.

Process Performance:

The Supplier warrants the following:

That the 28’ x 14.5’ SAG mill will draw at least 5,200 kW as measured at the motor shaft with:

	-		Ball charge in the range of 12% to 15% at a total charge of ³ 28%
	-		Pulp density in the range 65 to 75% w/w
	-		F80 less than or equal to 175 mm
	-		Mill speed in the range 73 to 77%

And provided that the following conditions are met:

	•		That the milling circuit is operated by experienced personnel
	•		That all auxiliary equipment is selected, installed and operated to suit the circuit requirements.

Page 4 of 6

     • That the milling circuit is fed an ore with a specific gravity ≥ 2.7

	4.4		General Features
			The equipment shall be the Supplier’s standard design and of heavy-duty construction suitable for the operating conditions specified.
			See Appendix B, Mill Components, and Appendix C, Mill Gearing, for a more detailed description of design and construction requirements for the mill.
