1 INTRODUCTION

Basados Canteras Del Hallazgo (CDH) are in the process of doing a trade-off study on ore

reserve access at the Chucapaca Shaft Project, situated in the Andes mountainous range in

the Moquegua district of Peru.

FIGURE 1: LOCALITY PLAN

The trade-off study will be based on the most feasible access configuration. It is the intention

to do a comparison between decline ramps and a vertical shaft complex, for the transporting

of men,material and rock to the underground workings. The study considers both capital

(CAPEX) and operating (OPEX) cost.

WorleyParsons have been given the contract to evaluate the shaft complex requirements as

part of the trade-off study.

This report outlines the optimal vertical shaft configuration and services selected to support

the CAPEX and OPEX submitted.


209050-00014-000-GE-REP-0001 7 Rev 0 (04-Feb-14)

2 EXECUTIVE SUMMARY

WorleyParsons has concluded the study based on sound engineering practices in terms of

the shaft infrastructure and in accordance with user requirements given by CDH. The

request was that the study be done to an accuracy level of 30% in terms of the estimate and

50% in terms of labor

The scope of work given by CDH is as follows:

• Surface infrastructure;

- Winding plant and associated services

- Lamproom and shift control centre

- Ore handling facilities

• Vertical shaft infrastructure for men, material and rock hoisting;

• Loading arrangements;

• Shaft pumping and spillage arrangements;

• CAPEX and OPEX for the shaft infrastructure only.

An optimal shaft dimension was found to be 5 m diameter by 455m deep. This will facilitate

the hoisting of men, material and rock.

Ore handling facilities include the conveying of ore to a stockpile and waste conveying to a

bin from where it will be transported by truck to the process plant and waste dump facilities.

The resultant capital requirements are tabled in Table 1 and Figure 2 represents the

distribution of the CAPEX :

5 TECHNICAL REPORT

5.1 Surface layout

In Order to establish the footprint of the surface area to be terraced, the area required for the

sinking contractor was established to house the following:

• A contractor yard for site offices, consumable and equipment storage and workshop

facilities;

• A laydown area for stacking of jigged bunton sets and guides;

• Ring fencing of the surface area for construction and operational security.

Figure 5 represents the area required and includes the proposed layout for the winding

plants, headgear and Lamproom:


209050-00014-000-GE-REP-0001 14 Rev 0 (04-Feb-14)

FIGURE 5: GENERAL SURFACE LAYOUT

The layout is conceptual and can be optimised with the project going forward


209050-00014-000-GE-REP-0001 15 Rev 0 (04-Feb-14)

5.2 Winding plant

The preferred winder configuration selected was standard double drum winders. For the

purpose of standardization, motor drives are proposed to be duplicated. Squirrel cage AC

motor drives are recommended and these are standard motors readily available.

Provision is made for a spare motor as the turnaround time for repairs is excessive.

The winders are equipped with the following:

• Controlled braking;

• Upper and lower limit overwind protection;

• Over-speed protection;

• Slack/tight rope monitoring;

• Rope coiling protection;

• Man/material winding speed – 7 m/s (regulated);

• Rock winder speed – 9 m/s (regulated);

• Factor of Safety of winder ropes – 5 (regulated);

• Minimum drum over rope diameter – 80 (regulated);

• Locked bell system (Beltronic or equivalent);

• Ecam communication systems.

The rock winder duty is tabulated in TABLE 4.

5.3 Ropes and attachments

Standard galvanized triangular strand ropes with fiber core were selected. One set of spare

ropes per winder is provided for.

Cappel attachments, commonly used in Peru, were selected for ease of attachment to the

conveyances (no splicing). Humble hooks with resin sockets may be the client’s preference

and can be provided for. A spare set of attachments are provided for each winder.


209050-00014-000-GE-REP-0001 17 Rev 0 (04-Feb-14)

5.4 Conveyances

• Rock hoisting skips

Standard bottom discharge skips with a camel back opening cam was selected and includes

a trigger arm locking device to prevent the inadvertent opening up of the skips in transit.

Spare skips are provided for.

Underslung inspection/repair baskets are provided for each rock compartment;

• Man/material hoisting

A double deck cage configuration was selected with roller shutter doors. Slinging lugs are

included for the slinging of long material and the attachment of the inspection baskets.

A counter weight conveyance with a capacity of 70% of the attached load for men/material

hoisting has been accounted for.

Underslung inspection/repair baskets are provided for the man/material compartment and for

the counterweight compartment.

5.5 Shaft configuration

The shaft diameter was selected on the basis that the maximum lump size for rock will be

300mm. The minimum footprint for the skips should therefore be no less than 1m by 1m.

Smaller dimensions will result in rock hanging up during skip discharge. Considering the fact

that material cars are to be transported in the cage, a 5 m diameter shaft was selected with

a cage footprint of 2.5 m long by 2.1 m wide. It should be noted that material, chutes and

boxes need to be designed, taking cognizance of the limited footprint.

All service piping is placed in areas for ease of access for installation and maintenance

purposes. Shaft cabling is housed in front of the 2 deck conveyance to facilitate the

installation of the shaft cabling via the 2 decks of the man/material conveyance. This position

is convenient for installation via the 2 deck man cage and for future maintenance purposes.

Figure 2 represents the shaft configuration selected.


209050-00014-000-GE-REP-0001 18 Rev 0 (04-Feb-14)

FIGURE 6 : SHAFT CONFIGURATION

5.6 Loading arrangements

The reef production is 3000 t/d or 1500 t per production shift. For the purpose of this study, it

is assumed that the storage capacity for reef, to the loading station, should be approximately

equal to that produced during 1 production shift. Considering the low tonnage of waste, a 2.4

m diameter ore pass of 350 ton capacity will suffice. A 5m lined silo (use shaft formwork for

lining) with a capacity of 1900 t lined silo is recommended for reef storage underground.

Standard belt and flask loading arrangements are proposed with flask loading cells and spill

free flask discharge arrangements. Interlocking between the winder, flask discharge and

loading belt is provided for. Changeover from ore to waste, and vice versa, will be

interlocked to ensure the system is set up to load and discharge to the appropriate surface

stockpile/silo.


209050-00014-000-GE-REP-0001 19 Rev 0 (04-Feb-14)

Figure 3 represents the loading arrangements accounted for:

FIGURE 7 : PROPOSED LOADING ARRANGEMENTS

5.7 Shaft spillage arrangements

The relatively low production tons and the introduction of spill free loading arrangements, will

result in minor spillage handling requirements.

A decline equipped with a spillage winch and a 2 t tipping hopper is proposed. The hopper

will discharge directly onto the loading belt via an ore pass.

Cage loading of spillage cars via an established platform below the spillage box could be

investigated as part of optimization going forward with the study.

Figure 8 represents a schematic of a typical loading arrangement proposed for this project:

6.2 Service water supply

For the calculation of service water, the following ratio of water consumption per ton mined is considered:

• 0.75 m³ of water / Ton mined;

• The daily production is 3,800 Ton/day;

• The daily service water consumption will then be 2 850 m³/day.

It is assumed that 70% of water is consumed during the drilling period that is approximately 5.5 hours in duration, if there are two shifts per day, it will be 11 hours of drilling per day, thus, the peak water flow will be 182 m³/hr or 51 l/s.

The pipe nominal size required for this flow is 150 mm diameter. A Schedule 40 pipe is required for the 400 m head

Each working level will have a pressure reducing valve station (PRVS) to reduce pressure to a maximum pressure 10 bar feeding the workings.

See FIGURE 8 for more details:


209050-00014-000-GE-REP-0001 24 Rev 0 (04-Feb-14)

FIGURE 9 : SERVICE WATER RETICULATION

6.3 Compressed air service system

For calculating the Compressed air requirements, the following ratio of compressed air

consumption per tons mined is considered:

• 0.13 kg/s air / 1000 ton broken;

• The daily production is then 3,800 ton/day.

Thus compressed air consumption will be 0.494 kg/s, at normal conditions (density of 1

kg/m³), the Air flow will be 0.494 m³/s (29.64 m³/min).

The altitude of the mine is approximately 5000 AMSL, the atmospheric pressure being 55

kPa (a).

Assuming a site temperature of 10°C flow of free air is calculated to be:


209050-00014-000-GE-REP-0001 25 Rev 0 (04-Feb-14)

Where:

• qFAD: Flow rate to the operation site conditions;

• qN: Flow Rate to the Normal Conditions;

• TFAD: Site Temperature in K, for this case is 10°C (283K);

• TN: Temperature to Normal Conditions in K, 20°C (293K);

• PFAD: Site Atmospheric Pressure in bar is 0.55 bar;

• PN : Pressure at Normal Conditions in bar is 1 bar.

Thus the flow at altitude (qFAD) is 52.1 m³/min.

The pipe nominal size required for this flow is 150 mm diameter.

The Air pressure required in the operations is 4.5 bar minimum, the pressure drop for this

pipe size and flow is approximately 0.016 bar per 100 meters of pipe.

A 150 diameter Schedule 20 A53 Gr.B steel pipe is selected.

6.4 Dewatering system

The dewatering flow required is 20 l/s and the discharge level for the water is 4,600. The

dewatering system will be located at the shaft bottom (level 4,442). The proposed system for

dewatering consists of the following:

• The mine water collects in a sump located at the shaft bottom. This sump has two

vertical spindle pumps (one stand by) installed. These pumps are 5HP, 20 l/s. These

sump pumps sends the water to a containment pond of 72m3 (retention of 1 hour) also

located at the shaft bottom. . This retention pond is about 3x4x6m. The pond feeds

the main pumping system. The pipe length from the sump to the pond has been

estimated in 25m. The pipe will be a 150 mm diameter steel pipe (A53 Gr.B), Schedule

40, Flanged Class 150;


209050-00014-000-GE-REP-0001 26 Rev 0 (04-Feb-14)

• The main pumping system consist of two positive displacement pumps of 22 kW @ 20

l/s delivery each (one on standby). This pump sends the water to the discharge point

located on level 4,600 from where it will be gravitate out the mine. For the required

flow, the pipe will be 100 mm diameter schedule 40 and the total length of the pipe will

be 225 m;

See FIGURE 3 for schematic of the proposed dewatering system.

8 CONCLUSION

WorleyParsons have concluded the study using sound and proven engineering practices in

terms of ore handling and shaft infrastructure. Where possible, quotations were obtained

from suppliers and the balance of the costs was derived from recent projects as per the data

base.

In terms of the shaft configuration, it is proposed that the potential to transport all equipment

down the vertical shaft, hence eliminating ramps to the workings, be considered in the next

phase of the project. This is considered to be optimal in terms of shaft designs but, early

extraction of ore is key to the project, and may be an overriding factor in the provision of the

proposed ramps.
