4.0 PROJECT DESCRPTION

4.1 GENERAL

The scope of work the Cobriza Expansion Project covers minedevelopment, mine equipment, new process plant, expanded or newsupport services and facilities, townsite housing, land development andtownsite services.

The new process plant replaces the existing process plant.

The new process plant receives run-of-mine ore from bottom dump railcars discharging to the primary gyratory crusher. The ore is thencrushed, ground and concentratred by flotation. The copper concentrateis thickened and filtered and discharge to final concentrate storage.Trucks are loaded with concentrate by front end loader for transport to asmelter. The tailings are thickened and filtered and discharged into theMantaro River by gravity.

Water for the new process plant is obtained from the Rio Huribama.Water flows bye gravity to storage tanks at elevation 2387 m, providingsufficient pressure (by gravity) at the concentrator.

Electrical power is supplied from the Rio Mantaro Power System througha new transmission line terminating at new transformers located withinthe substation enclosure on Pampa de Coris, north of the new processplant.

The new process plant is designed to process 3,500,000 stpy of ore at anominal feed rate of 10,000 stpd and, by conventional flotationconcentrating techniques, produces 224,000 stpy of copper concentrateessaying 25.4% copper.

The ore, consisting primarily of massive sulfides, contains an average of1.8% copper in chalcopyrite mineralization.

In this manual, the ore concentrating plant is divided into seven (7)major parts: Electrical Power Supply; Water Supply; Primary Crushingand Coarse Ore Storage; Grinding, Flotation, Thickening and Filtering;Reagent Processing, Storage and Distribution: Tailings Disposal;Process Sampling; and Misceññaneous Ancillary Facilities.

4.2 PROCESS


4.2 PROCESS (cont’d)

a) Electrical Power Supply and Distribution System

Electrical power will be supplied from the Rio Mantaro power systemthrough a 60 kV transmission line, terminating at two 60/10/4-16 kVtransformers located within the substation enclosure on Pampa deCoris.

The proces plant power distribution systems are fed from these twotransformers based on teh two (2) bution and 4.16 kV for large motorssuch as the grinding mill motors.

The transformer secondaries are connected to switchgear also locatedin the substation. This switchgear then distributes both 10.0 kV and 4.16kV to switchgear/motor controllers mounted in lectrical control roomslocated in the Primary Crushing Building, Fine Crushing Building,Grinding Building and Flotation Building. The electrical control rooms arelocated to provide minimum length of run to the specific point of use.

b) Water Supply and Distribution System

Water for the process plant is obtained from the Huaribamba River,utilizing the existing intake and settling basins. The water flows bygravity through a pipeline to two storage tanks at elevation 2387 m,providing sufficient pressure (by gravity) at the process plant. One tankholds the fire water reserve in the lower portion of the tank and freshwater supply above the fire water reserve. The other tank holds processwater made up of river water and up to 50% reclaimed process waterfrom the tailings thickener overflow settling pond. Fresh make-up wateris discharged into the settling pond to mix eith the reaclaimed waterbefore it is pumped to the process water storage tank.

c) Primary Crushing and Coarse Ore Storage

This portion of the plant extends from teh run-of-mine ore feed to theprimary crusher, through primary crushing and coarse ore storage.

7.0 ELECTRICAL AND INSTRUMENT CONTROL FEATURES AND DEFINITIONS

7.2 TERMS AND DEFINITIONS

Terms used throughout the electrical controls descriptions and thestart-up procedures are defined as follows:

Unless otherwise described on the individual description sheets, start-stop controls will mean a “start” pushbutton and a “stop” pushbutton ofthe momentary contact type, wich will have to be depressedmomentarily to either start or stop the equipment.

A colored light which comes or glows when a given condition exists.

An electrical contact which prevents operation out of sequence so thatif the equipment stops, preceeding equipment is automatically shut offand has to be restarted in proper sequence.

a) Power Source: 460V Reclain Pumps MCC-P6A (06-8901) andP6B (06-8902).

b) General: The water reclain system consists of a series associatedsequencing control circuitry. Sequencing is accomplisehd bymeans of a sixteen (16) step eight (8) circuit programmer and isset to “cycle” the pumps sequentially as the water level variesfrom “low level” to “high level”.

There is a time-delay of approximately ten (10) seconds betweenstart up of each motor programmed for start to avoidsimultaneous starting.

The maximum number of motors that will be permitted to run atany one time, with the “Selector” switches in the “auto” mode isthree (3). Each motor is provided with a space heater which isactivated by its contactor when the motor is stopped.

c. Controls: Each motor is provided with an auto/manual “Selector”switch (SS1) and a “Local” start/stop/lock-out switch (PB1). The“Selector” switches for motors 06-1501-M and 06-1502-M areinstalled in MCC-P6B. Both MCC’s are located in electrical roomNº6 (south of the “Reclaim Water Settling Pond”). In addition, tehcontrol circuit incorporates the use of a system of control relays,time delay relays, level switches and a sequencing programmer.

d. Status Indication: Status indication for each motor is provided bymeans of a “Red” running light located on its associated motorcontrol center. (When motor is stopped, light is “off”).

e. Alarms: The water reclaim system is provided with a “low level”alarm bell amber indicating light and alarm silence switch, all ofwich are located on vendor surnished panel (LSL-6016) in thevicinity of the reclaim pumps.

f. Interlocks: Each motor is interlocked with the “low level” switchand “high-high-level” switches (LSL-6016 and LSHH-0004)respectively. In addition, each motor is interlocked through thesequencing programmer when in the “Auto” mode.

g. Start-Up. Start up may be initiated by first selecting the “Auto ormanual” mode.

In the manual mode, each pump motor may be started independently byoperating its assciated “Local” start switch (PB1). The motor will startprovided the following conditions are met:

1. Main Braker power is on.2. “Local” lock-out is removed3. Water level is above “low-level” (LSL-6016 closed).4. Water level is below “high-high-level” (LSHH-0004 closed).5. All components are functioning normally.

In the “Auto” mode, each motor will start in sequence and be “cycledautomatically by the sequencing programmer provided the sameconditions as required for the “Manual”” mode above are met.

h. Shut-Down: In the “Manual” mode each motor may be shut downby operating its associated “Local” stop switch (PB1). In addition,all motors will shut down automatically and simultaneously (in themanual mode) if the water level is below the “low-level” limit orabove the “high-high-level” limit. (LSL-6016 or LSHH-0004opened.)

In the “Auto” mode, each motor will shut down (and eventually re-start)automatically and sequentially as dictated by the programmer. Inaddition, all motors will shut down automatically and simultaneously ifthe water level exceeds the “low-level” or “high-high-level” limits.

SYSTEM DESCRIPTION

Fine Ore Reclaiming and Primary Grinding

Fine ore reclaiming and primary grinding consists of two identical circuits.The following description is typical for either circuit.

Ore is reclaimed from the fineore storage stockpile by three variablespeed belt feeders, discharging material onto a belt conveyors whichconveys the ore to a first-stage grinding ball mill. A belt scale is installedon the conveyor for feed control and to continuosly measure the flow rateand total tonnage of material being fed to the grinding circuit.

Primary grinding is performed in two stages. The first stage ball mill is inclosed circuit with a bank of hydrocyclone classifiers. First stage classifieroverflow reports to the discharge sump of the second stage mill, which isalso the feed sump for the second stage cyclone.

The second stage mill discharge and the overflow from the first stagehydrocyclone report to a bank of second stage hydrocyclones in closedcircuit with a second stage grinding mill. Second stage classifier overflowis finished flotation feed reports to agitated conditioning tanks.

Rougher – Scavenger Flotation

Overflows from the conditioning tanks are treated in two identical parallelrougher-scavenger flotation circuits.

Regrind hydrocyclone overflow is combined with the flow from theconditioner tanks and pumped to Rougher I flotation. Tails from RougherI flotation flows to Rougher II flotation , thence to Scavenger I flotationand thence to Scavenger II Flotation. Scavenger II flotation tails flow tothe final tailing sump and then to the tailings thickener.

Rougher I concentrate is pumped to second Cleaner flotation andRougher II concentrate is pumped to First Cleaner flotation. Scavenger IIflotation concentrates are combined and then pumped to regrind.

Cleaner Flotation

Upgrading of concentrates from Rougher I and Rougher II slotation isaccomplished in three cleaner flotation stage utilizing countercurrentflow of tails.

Rougher II flotation concentrate and Second Cleaner flotation tails arecombined and then pumped to First Cleaner flotation. Rhe resulting tailsreport to regrind and the concentrate is combined with Rougher Iflotation concentrate and Third Cleaner flotation tails and then pumpedto Second Cleaner flotation. Second Cleaner concentrate is pumped toThird Cleaner flotation and the resulting concentrate is then pumped tothe concentrate thickener.

Regrind

Sacvenger concentrates and First Cleaner flotation tails are combined,forming the feed for regrind. The regrind circuit consists of two parallelcircuits each with a ball mill in closed circuit with a bank of hydrocycloneclassifiers. The feed is split between the two regrind circuits bye meansof a static distributor. The hydro-cyclone overflow is combined with theconditioner tanks overflow is combined with the conditioner tanksoverflow and reports to Rougher I feed pumps.



General

Maintenance of the equipment within the grinding area is performed by a25/5 short ton capacity overhead travelling bridge crane andmaintenance of the equipment within the flotation area is performed by a10 short ton overhead travelling bridge cranes are serviced by monorailhoists.

Mill liner maintenance is performed with an electric/hydraulic linerhandling machine.
