Dear Noel,

Subject: LETTER OF COMFORT

1. Introduction

Recitals

	 	 	 
	1.1 LGL:

	 	Lihir Gold Limited seeks formal consent from the Lihir Mining Area
Landowners Association (LMALA) to proceed with the Million Ounce Plant Upgrade
(MOPU) project, and assurances that the project will proceed without disruption.
	 
	 	 
	1.2 LGL:

	 	Lihir Gold Limited has offered K40 million of the MOPU funds to assist
LMALA gain authorization and uninterrupted access to undertake the MOPU project.
	 
	 	 
	1.3 LGL:

	 	Lihir Gold Limited initially offered the K40 million and expected it to be
released over the three years of the MOPU project. LGL now understands and accepts
that the funds may have to be released in good faith before formal landowner
approval and consent can be obtained to commence the MOPU project.
	 
	 	 
	1.4 LMALA:

	 	Before LMALA can introduce new agreements and undertakings that will
enable LMALA to seriously start awareness about MOPU, outstanding pre MOPU issues
must be addressed by LGL. In particular the following:
	 
	 

	 	- Putput Community Agreement and the 3 specific projects within that
Agreement. (Relocation, Plant Site, Gorgor
	 
	 

	 	- Physical Development Plan
	 
	 

	 	- Alternate Financing System
	 
	 	 
	1.5 LMALA:

	 	LMALA have subsequently proposed to LGL its preferred approach to
obtain the consents and assurances LGL seek. This includes upfront,
rather than phased, access to all funds and an indication that funds will
need to be made available to it before formal landowner consent can be
obtained.

1

 

	 	 	 
	1.6 LMALA:

	 	LMALA has a proposed approach to the introduction of MOPU but believes
this will be futile unless clause 1.4 in these recitals can be properly addressed
in order to give the affected landowners the comfort they need to proceed with any
new agreements and undertakings.

2. Purpose of this letter

The purpose of this letter is to clarify to LGL the strategy LMALA will employ to do all things
reasonable to assure LGL that the MOPU project can proceed unhindered.

LMALA acknowledges that for LGL to make available to it K40 million of the funds, it needs comfort
that the outcomes it seeks will be obtained, and the funds will be distributed in an appropriate
manner.

The purpose of this letter is to provide both comfort and understanding to LMALA and LGL.

3. Overview of strategy to be adopted by LMALA

To assist in the effective dealings with its members, LMALA has commenced the strategy of forming
a team which represents high profile landowners and, where required, specific block owners in each
of the affected areas (“Specific Issue Companies”). The strategy includes areas currently affected
and those who will be affected by virtue of the MOPU project including:

	 	 	 	 	 	 	 	 	 	 	 	 	 
	 	 	•	 	Caldera (Pit)	}
	 	 	 
	 
	 	 	•	 	Balasie (Process Plant)	 	 	 
	 
	 	 	•	 	Kunaye (Airport)	 	 	 
	 
	 	 	•	 	Londolovit Weir	 	 	 
	 
	 	 	•	 	Town	 	 	 
	 
	 

	 	•
	 	Hurtol
	}
	 	 	 		 	K40 Million
	 
	 

	 	•
	 	Sianos
	 	 	Proposed Dam Area	 	 	 	 
	 
	 

	 	•
	 	Talies	 	 	 	 	 	 	 
	 
	 	 	•	 	Villages along the easement to Hurtol	 	 	 	 
	 
	 	 	•	 	Other affected areas or parties.	 	 	 	 

Attachment 1 is a map which outlines the corporate entities and the areas they represent. This
does not include the proposed dam or the road easement areas as specific issue companies have not
been formed for these areas yet.

Attachment 2 is a schedule detailing the specific details relevant to each block.

The strategy broadly involves establishing these Area Companies and working through them to reach
agreement and ultimately obtain consent to MOPU, and uninterrupted operation.

4. Area Companies

a. The Area Companies — Ownership & Operation

The ownership of each Area Company will be allocated on the basis of

2

 

Each block will be represented by a block executive. Where more than one block is held, there will
be only one executive. All of the block executives (shareholders) for an area will collectively
appoint a board of directors to oversee the activities of the Specific Issue Company (SIC), and
this will include representatives from the executive of either Anitua or Lihir Business Services
(LBS).

b. The Area Companies — Their Purpose

It is recognized that the SIC co-exist with clan based companies (with an area generally
comprising more than one clan) and family or personal companies.

The purpose of the SIC is to provide one single commercial entity with whom LMALA, LBS and Anitua
can deal. It is expected that this will reduce the occurrence of specific block owners acting in
isolation and promote rationalization of funds and increased consistency in dealings.

LMALA recognize that the clan based companies continue to be the primary shareholders in the
Anitua group and that the strategy being implemented over recent years aimed at Anitua is purely
clan owned (rather than having individual shareholders) remains.

LMALA also recognize the continued and necessary existence of family owned businesses. The
expectation is that the SIC will, as appropriate, provide financial resources to these family
businesses subject to approval from the SIC board and executive. Attachment 3 outlines these
relationships.

5. The process of obtaining consent

LMALA, LBS and Anitua have already commenced the process of meeting with area block owners and
outlining the strategy to create and utilize the SIC. Consequently we believe the process has
already started.

To support the strategy LMALA requires confirmed access to funding from LGL. These funds will form
the seed funding that will be leveraged by the SIC to both generate ongoing income for its
shareholders (the area block owners) and provide a source of funding for family companies seeking
to capitalize on business opportunities.

Insofar as LGL addressing recital 1.4 and in return for the K40 million funding, LMALA will work
diligently with the SIC to do everything reasonable to ensure LGL has the access it requires to
undertake the MOPU project.

Attached (Attachment 4) is a copy of a presentation to the Saberte SIC that was instrumental in
gaining support and consent to access the Kapit area for the stockpile relocation. Whilst this is
not part of the MOPU project, it is indicative of the methodology LMALA will adopt with the
Special Interest Companies.

a. The Agreements with Area Companies

Attached (Attachment 5) is a copy of one of the Agreements already in place with the Saberte
(Kapit) SIC. Whilst this Agreement does not relate to the MOPU project, it is the model that has
been introduced into the Caldera, Balasie, Londolovit and Kunaye SIC’s There is also a an
Agreement between LMALA and the individual block executives (Attachment 6) for the Saberte SIC
that in all likelihood would also be introduced into the MOPU SIC’s

Release of Funds by LGL

LMALA acknowledges that LGL requires visibility in regard to the use of the
funds. This includes LMALA providing evidence that the SIC Directors are
aware that the funds were provided by LGL and made available by virtue of
MOPU. Such evidence will be provided by way of signed minutes of meetings.

LGL will release K20m of funds within 14 days of this letter, and will release
a further K20m within 28 days from the date of this letter.

The funds shall be released as loans from LGL into the SIC accounts.

Any movement of the funds shall require three signatories of which a minimum
of 2 must be “A” signatories and one “B” signatory. The chairman of the SIC
board will be eligible as a “B” signatory and “A” signatories shall be from
senior management personnel of both LBS and Anitua. No cheque shall be signed
without duly completed cheque requisitions. All CAPEX expenditure must have
unanimous board approval.

7. Use of funds

LGL acknowledge that expenses will be incurred as part of its efforts to
obtain consent. LMALA will ensure that such expenses are appropriate, and
paid from the K40m of funds available for MOPU.

LMALA acknowledges that LGL requires the funds, other than expenses, to be
allocated solely to SIC and other affected areas that may be determined and
agreed upon by both LMALA and LGL. LGL acknowledges that LMALA will determine
the split of funds between the SIC’s.

8. Intention — Consent and Uninterrupted Operations

LMALA acknowledges that LGL seeks consent to proceed with the MOPU project
uninterrupted.

Consent is understood to mean that the landowners of Lihir, through
their representative LMALA, agree that the MOPU project can proceed
unhindered. Such consent will be provided in writing, by me as Chairman of
LMALA, with the expectation that it will be tabled by LGL with the Mineral
Resource Authority (MRA). LMALA acknowledges that MRA will likely require the
process by which LMALA obtained consent to be outlined and agree to provide
such outline in writing if required.

4

 

LMALA also acknowledges that LGL seeks uninterrupted operation. LMALA considers this means
no disruption to ongoing operations or MOPU construction activities. Should any dispute occur,
LMALA, Anitua and LBS will actively work to restore normal operations. Should any dispute occur
that affects MOPU but is not relevant to any of the agreements and understandings that LMALA has
with the SICs, then LGL will at its cost work with LMALA to rectify the issue, e.g. should an LGL
vehicle run over a pig along the easement road to Wurtol then this would be outside of any
understanding between LMALA and LGL in relation to MOPU.

LMALA wishes to see the MOPU project be given Government approvals from such entities as the DEC
and the Environment Council as well as MRA and the MRA chaired State Team. As such LMALA will also
assist LGL and lobby these entities where necessary for the approvals to be given in a timely
manner.

9. Timing of Consent

LMALA acknowledges that consent to proceed with the MOPU project is a fundamental outcome giving
rise to LGL’s preparedness to make available the K40 million.

As Chairman of LMALA, I confirm my stated view that following the rollout of the strategy to each
of the affected areas, it is my expectation that consent will be given as soon as practical
thereafter in accordance with the timetable outlined earlier in this letter.

10. Conclusion

We thank you for your demonstration in trust of LMALA by supporting our strategy and look forward
to providing you with your desired outcomes.

Yours sincerely

8 PROJECT DOCUMENTATION

	All project documentation including reports, datasheets, databases, drawing lists, purchase
information, IOM documentation, etc shall comply with the Project Instructions, Standard
Specification for Vendor Documentation (Specification A003) and Standard Specification for Piping
Information (Specification A005).

In particular:

	 	•	 	Information shall be collated in the identified formats to facilitate ready
incorporation into other project databases.
	 
	 	•	 	Each document shall be cross referenced against all relevant equipment items to
enable database searching by equipment number.
	 
	 	•	 	All pdf documents of greater than 10 pages length shall include interactive
bookmarks to allow ready navigation to each item in the document table of contents.

9 CORRESPONDENCE

9.1 GENERAL

For ease and currency of communication, project correspondence will be handled by email wherever
possible. Without exception, every email shall be structured as follows:

	 	•	 	The email shall be addressed to both the project email address
and the intended recipient of the email.
	 
	 	•	 	The caption in the email subject line shall be of the form AAAA-BBBB-C-DDD-EEEE,
where AAAA is the Project ID Code, BBBB is the relevant four character work package
number (eg Contract Number or Purchase Order number), C is single character code
identifying the email originator (as

			
	 	 	 
	MOPU-0000-02-S-Project Reference
	 	Page 6 of 15

 

Table of Contents

	 	 	 	identified below), DDD is a sequential correspondence counter for the particular
Contract, and EEEE is a descriptive title (of as many characters as required) to clearly
identify and distinguish the email subject.

Emails from LGL shall have the originator code “L”, emails from the Design Coordinator shall have
the originator code “D” and emails from all other Consultants, Contractors or Vendors shall have
the originator code “C”. Each organisation assigned to the project shall maintain their own
separate correspondence counter.

9.2 FORMAL TRANSMITTAL OF INFORMATION

Consultants / Vendors shall ensure that all formal transmittal of drawings and documentation to
LGL, whether by email, disk or hardcopy, is accompanied by an electronic transmittal form in
Microsoft EXCEL that identifies the following:

	 	•	 	A sequential transmittal number.
	 
	 	•	 	The electronic filename and a description of each drawing / document being
transmitted. Suitable descriptions would include the last two lines of a drawing
titleblock or a brief summation of document purpose or content.

Any covering email shall also include the word ‘Transmittal’ in the descriptive title component of
the subject line.

The purpose of these requirements is to enable ready collation of information from varied sources
into a comprehensive project database. Transfers of drawings and documentation which do not meet
these criteria will be treated as issue for information purposes only and the relevant drawings /
documents will not be registered in the project database.

In the absence of any other agreed format for the transmittal form, the Standard LGL Transmittal
(Specification A008) shall be utilised.

10 TECHNICAL SPECIFICATIONS

All design and construction shall comply with the relevant standard specifications listed in
Appendix C.

11 SURVEY DATUMS

Unless otherwise indicated all coordinate and level information for the MOPU upgrade project
shall be based on the “Lihir Grid” which is a plane coordinate system in metres aligned on AMG
North. The site position datum is PSM 12340 “UNIFORM 8” with the following characteristics:

	 	 	 	 	 	 	 	 	 
	 	 	Coordinates and	 	AMG Coordinates
	Parameter	 	RL to "Lihir Grid"	 	and RL
	Easting
	 	 	11843.12	 	 	 	461842.3	 
	Northing
	 	 	5030.31	 	 	 	9655030.1	 
	RL
	 	 	18.50	 	 	 	18.60	 

The “Lihir Grid” bearing is AMG plane bearing at PSM12340.

It is to be noted that the site also uses a second level datum for the mine pit and general
topographical survey. This mine datum is based on a level at PSM 12340 of RL1018.50 and conversion
to the project level datum entails subtraction of 1000.000m. Certain survey / reference
information provided to Consultants and

			
	 	 	 
	MOPU-0000-02-S-Project Reference
	 	Page 7 of 15

 

Table of Contents

Vendors may reflect the mine datum and should be converted to the project datum as required
to support design and construction.

12 COMMUNITY PROVISIONS

Continued engagement of the local community will be critical to the success of the upgrade
project and all engineering design and construction shall be consistent with the intentions of the
project Community Engagement Strategy and Contracting Plan. In particular, design and construction
planning shall aim to maximise opportunities for local contracting or labour hire services wherever
it is possible to do so without compromising other principles of cost effectiveness, scheduling,
quality, and ooccupational health and safety. The key capacities by which the local community could
support the project include:

	 	•	 	General earthworks and drainage construction.
	 
	 	•	 	Construction of culverts, gabions and other site works.
	 
	 	•	 	Bending of rebar for concrete works.
	 
	 	•	 	General concrete construction for minor slabs and footings.
	 
	 	•	 	Supply of pre-cast concrete units.
	 
	 	•	 	Prefabrication of pipe spools.
	 
	 	•	 	Construction of buried piping.

13 SOIL GEOCHEMISTRY

Soil / soil pore water can be relatively aggressive in some parts of the site as a
consequence of the volcanic origins of most materials. Unless specific soil test information is
available for the immediate footprint of the works, the following worst-case soil geo-chemistry
shall be assumed for design purposes:

	 	•	 	pH 5.4
	 
	 	•	 	Chloride concentration of 50-60 mg/kg Cl
	 
	 	•	 	Sulphate concentration of 200 mg/kg SO4

14 EARTHWORKS DESIGN CONSTRAINTS

14.1 SOURCING OF BORROW MATERIAL

An existing basalt quarry operated by a local cooperative is located adjacent to the Londolovit
Weir (approx 10km one-way haul from process plant site). Development of additional hard-rock
quarries is likely be problematic from a community relations perspective and it is envisaged that
the supply of concrete aggregate and crushed rock will be limited to the output of the existing
quarry and crushing plant..

Similarly, limestone / coronus material for filling of building pads and capping of working areas
will have to be sourced from existing road works borrow pits in the NE of the island (approx 20km
one-way haul) or proposed borrow pits along the Wurtol pipeline route (approx 10km one-way haul).
Readily accessible coronus reserves are limited in quantity, and are also in heavy demand for
other mine maintenance and community projects.

Given the constraints on material availability and potential issues associated with

			
	 	 	 
	MOPU-0000-02-S-Project Reference
	 	Page 8 of 15

 

Table of Contents

heavy truck traffic along local roads, a design that minimises the required extent of
material import will be preferable.

14.2 DISPOSAL OF EXCAVATED SPOIL

Flat land on Lihir Island is at a very high premium and there are few sites for ready disposal of
excavated spoil — especially poor quality material. As a consequence the earthworks design should
attempt to minimise the extent of excavation wherever practical.

15 ECONOMIC COMPARISONS

Where economic comparisons are required to evaluate different options, they shall comprise
assessment of net present cost (NPC) based on the following:

	 	•	 	Equipment arrangements and equipment numbers shall be taken as given.
	 
	 	•	 	Pipe sizing and material specifications identified through the pipe labelling are
indicative only and shall be confirmed through design.
	 
	 	•	 	Valving arrangements are preliminary only and shall be amended as required to meet
specified isolation and control requirements.
	 
	 	•	 	Code ‘BL’ refers to a battery limit between different packages of work or different
facilities.
	 
	 	•	 	Code ‘Tl’ refers to a tie-in to an existing pipe or existing item of equipment.
	 
	 	•	 	Tie-ins have been shown where identified to date, but it shall be a requirement of
this package of work to determine the specific location and details of all tie-ins
required to complete the works.
	 
	 	•	 	Clouding reflects drawing changes made during the course of the Feasibility

			
	 	 	 
	MOPU-0011-02-C Appendix 2A-2 Technical Scope of Work
	 	Page 5 of 36

 

Table of Contents

 

	 	 	 	Study design and does not necessarily reflect real physical changes to the works.
For the purposes of this package of work clouding on the drawings shall be ignored.
	 
	 	•	 	The drawings have been marked up with tie-ins and battery limits reflecting multiple
packages of work. The Consultant shall only be concerned with those limits identified in
the following tabulations.
	 
	 	•	 	The ‘2000’ series drawings (eg 130-FP-2003) cover new upgrade works. All other
drawings are mark-ups of existing drawings describing the current plant.
	 
	 	•	 	The ‘0701’ tag included in the drawing number block shall not be read as an integral
part of the drawing number. As per the Project Reference document, this tag merely
identifies work in progress on a new drawing.
	 
	 	•	 	The drawing titleblock and the drawing titles currently shown in the titleblock are
not final. A separate data-base of proposed titles is available from LGL if required.

5 TECHNICAL SCOPE

5.1 ORE RECLAIM

5.1.1 Included Facilities

This Section 5.1 covers Facilities 1322 and 1325.

5.1.2 Background

The existing stockpile reclaim system comprises two 560 wet t/h under-pile apron feeders and one
emergency feeder serving the existing high grade ore (HGO) grinding circuit and one emergency
feeder serving the flotation grade ore (FGO) grinding circuit. The emergency feeders are fed by
front end loader, with all ore flow to the flotation circuit currently provided by this means.

The original design for flotation circuit allowed for two under-pile feeders but issues

over the road relocation required for an associated expansion of the stockpile footprint
precluded construction of the full reclaim system. Agreement has now been reached with the local
community for expansion of the stockpile but additional design input will be required for tie-in
to the as-constructed limits of the existing facility.

The existing HGO apron feeders are oriented perpendicular to the SAG mill feed conveyor and have
been installed with dribble conveyors. This has been done to place the feeders beneath the apex of
the annular stockpile. Due to their different orientation to the stockpile the under-pile feeders
for the flotation circuit have been arranged parallel to the flotation SAG mill feed conveyor and
no dribble conveyors are required.

The ore angle of repose is approximately 37 degrees but the draw down angle is typically 60
degrees and can be steeper with ores of higher clay content. As such, a dozer is often working to
assist mill feed.

5.1.3 Upgraded Operation

A new stockpile reclaim system is required to serve the second HGO grinding circuit being
developed for the MOPU project (refer Section 5.2). This new reclaim system shall comprise two
under-pile apron feeders and one emergency apron feeder. The under-pile feeders shall be located
on the plant-west side of the existing HGO feeders and shall be oriented perpendicular to the
discharge conveyor to maximise the area of stockpile available for direct feed.

The design of the reclaim system serving the second HGO grinding circuit shall be complete
including

	 	•	 	Under-pile / emergency feeders and associated equipment;
	 
	 	•	 	Reclaim and escape tunnels;
	 
	 	•	 	Tunnel ventilation and drainage systems;
	 
	 	•	 	The reclaim conveyor system comprising under-pile conveyor 1325-CV2010 which
daylights to the west of the existing grinding circuit, conveyor 1325-CV2011 which
traverses the face of the COS, and conveyor 1325-CV2012 which feeds the SAG mill.

Completion of the FGO reclaim facility to the original design requires extension of the
as-constructed tunnel and conveyor, and installation of the under-pile feeders. The existing
design for the tunnels, conveyors, feeders and associated equipment shall be reviewed and
additional design provided as required to complete the works. The design shall be cognisant of the
fact that one apron feeder for the FGO reclaim has already been purchased.

5.1.4 Specific Requirements for FEED

5.2 GRINDING AND CLASSIFICATION

5.2.1 Included Facilities

This Section 5.2 covers Facilities 1323 and 1326.

5.2.2 Background

The existing HGO grinding circuit consists of a SAG mill (8.53m diameter x 4.3m EGL, 4.8 MW motor)
in closed circuit with pebble crushers, and a Ball mill (5.79m diameter x 9.75m EGL, 4.8MW motor)
in closed circuit with hydrocyclones.

The commissioned capacity of the original circuit was 375 t/h (2.85 Mpta) based on approximately
86% operating time and with pebbles returned using a water injection system. In 2003, the circuit
was modified to include a separate pebble crushing capability and the capacity of the circuit has
subsequently been re-assessed as 4.4 Mpta at 86% operating time on design ore.

The current system has generally performed as designed and upgraded. On hard ores there have been
instances where additional power would have aided throughput. On medium blast ores there have been
periods of time where the circuit was ball mill constrained and additional capacity in the ball
mill would have allowed greater throughput — although it should be pointed out that the ball mill
constraint was at feed rates well above 4.4 Mpta.

5.2.3 Upgraded Operation

In order to accommodate the additional ore throughput associated with the increase in pressure
oxidation capacity an additional high grade ore (HGO) grinding circuit is required.

The new HGO milling circuit shall consist of a 5.5 MW SAG mill in closed circuit with

			
	 	 	 
	MOPU-0011-02-C Appendix 2A-2 Technical Scope of Work
	 	Page 9 of 36

 

Table of Contents

 

the existing, but upgraded, pebble crushers, and a 4.8 MW ball mill in closed circuit with
hydrocyclones. The mills will be of similar dimensions to the existing mills, although extra SAG
mill power has been allowed to improve the circuit capacity on hard ores. Wherever possible,
equipment shall replicate the existing HGO circuit to minimise spare parts holdings.

The open area on the eastern side of the existing SAG mill has been shown to be sufficient in size
to accommodate the new milling equipment in a mirror image layout to the existing circuit. The
area is tight, but the mills can be (and shall be) arranged with the same spacing as the existing
plant.

In terms of process transfer requirements, the SAG mill trammel undersize slurry shall be pumped
to the cyclone cluster while the oversize shall report to the existing pebble crushing circuit and
return to the SAG Mill feed belt via conveyors. The cyclone underflow slurry shall flow to the
Ball mill by gravity while the overflow product from the cyclone cluster shall report to a linear
trash screen before being transferred to the grinding thickeners.

The existing pebble crushing circuit shall be modified as required to accommodate the new mills.
The upgraded circuit shall be capable of twice the current throughput and have the flexibility to
return crushed scats to either milling circuit or split between the two.

5.2.4 Specific Requirements for FEED

5.2.4.1 General

The requirements of Front End Engineering Design (FEED) for the second HGO grinding facility shall
be defined by ‘Appendix 

2A-1, General Requirements for Engineering Design’ and this Section 5.2.4.

5.2.4.2 Issues

Specific issues to be addressed during FEED shall include:

	 	•	 	Optimum construction staging methodology to facilitate installation of the mills
given identified site access and site dimension constraints.

crane to new mills, if required.

	 	•	 	Comprehensive review of the existing pebble crushing circuit to establish upgrade
requirements for the following equipment:

	 	o	 	Conveyors;
	 
	 	o	 	Cone crushers;
	 
	 	o	 	Vibratory feeders;
	 
	 	o	 	Tramp metal magnets.

5.2.4.4 Piping Outputs

Critical pipework connections to be designed during FEED shall comprise all pipes extending beyond
the P&ID set identified in Section 2.2.

5.3 GRIND THICKENING

5.3.1 Included Facilities

This Section 5.3 covers Facility 1341, Facility 1348, Facility 1391 and the relevant parts of
Facility 1410 applicable to this scope of work.

5.3.2 Background

The grind thickening circuit in the process plant has the following functions:

	 	•	 	To reduce the solution chloride content entering the autoclaves as high levels can
adversely impact gold recovery or, if high enough, corrode internal metal components;
	 
	 	•	 	To increase the percent solids to the autoclaves for heat balance optimisation;
	 
	 	•	 	To recover process water that can be re-utilised elsewhere in the process and reduce
overall fresh water demand.

The original plant design incorporated one 35.5m diameter grinding thickener and two similar sized
CCD wash thickeners for oxidised slurries. In 2004 a second 38m diameter grinding thickener was
installed in series with the first due to increasing throughputs and the potential for higher
chloride levels from the Leinitz pit. However, chloride concentrations in the Leinitz ore were not
as high as predicted and so the original grinding thickener was converted to serve as an
additional CCD wash thickener in 2007.

The remaining 38m diameter grind thickener has insufficient area for the upgraded plant
throughput, and there is further potential that future ores from the Kapit pit may have higher
chloride levels than currently processed. Given this situation and other physical space
constraints imposed by the overall upgrade works it was decided the MOPU project would include for
a complete new grind thickening facility and that the existing grind thickener would be converted
to a fourth CCD wash thickener.

5.3.3 Upgraded Operation

The upgraded plant requires two 55m diameter thickeners installed to the east of the current
processing facility. The new installation shall include, but is not limited to, the following
equipment:

	 	•	 	Grind thickener tanks and associated underfloor access / escape tunnels;
	 
	 	•	 	Grind thickener mechanisms;
	 
	 	•	 	Underflow pumps;

			
	 	 	 
	MOPU-0011-02-C Appendix 2A-2 Technical Scope of Work
	 	Page 11 of 36

 

Table of Contents

 

	 	•	 	Process water (thickener overflow) collection tank;
	 
	 	•	 	Process water distribution pumps;
	 
	 	•	 	FGO concentrate thickener overflow collection tank;
	 
	 	•	 	FGO process water pumps from concentrate thickener overflow tank;
	 
	 	•	 	Reagent (flocculent) and utilities services.

The relocation of the grind thickening facility requires rerouting of all existing grind thickener
feeds to the new thickener location. In addition to this existing piping, new feeds from the Wurtol
raw water supply and slurry discharge from the second HGO grinding circuit will need to be
incorporated into the grind thickener feed.

The relocation of the grind thickening facility also requires hoppers and pumps to be installed in
both the existing and the new HGO grinding circuits to collect the trash screen undersize and
transfer it to the grinding thickeners. In the existing HGO grinding circuit the oxide sump shall
be converted to the new transfer sump with two new transfer pumps, operating as duty / standby. The
new HGO grinding circuit shall have a new sump installed with two new transfer pumps, operating as
duty / standby.

Normal operation of the grind thickening facility shall be as follows:

	 	•	 	The duty pump in each HGO grinding circuit shall pump the trash screen undersize to
the first grinding thickener feed tank. These slurry feeds shall mix in this tank with
the overflow wash water from the second grinding thickener. The combined slurry shall
then overflow to the first grinding thickener where the slurry shall be thickened to 50%
solids by weight.
	 
	 	•	 	The thickened underflow slurry will be pumped by one of two pumps, operating as duty
/ standby, to the second grinding thickener feed tank. It will mix in this tank with
fresh wash water. The combined slurry will then overflow to the second grinding thickener
where the slurry will be thickened to 50% solids by weight.
	 
	 	•	 	The thickened underflow slurry from the second grinding thickener will then be
pumped by one of two pumps, operating as duty / standby, to the Pre-Oxidation Feed Tanks.
	 
	 	•	 	The overflow from the first grinding thickener shall gravitate to a new process
water tank from which it shall be pumped to users throughout the processing plant.

In addition to the above, the design of thickeners and associated systems shall be such that it is
possible to install the two thickeners in separate staged construction. The design shall also
accommodate operation with either grind thickener taken out of service.

The overall plant upgrade will result in increased production of and demand for process water and
the existing process water circuit does not have adequate capacity to handle the increased flows.
The scope of work for this package shall include for all equipment, infrastructure and control
systems necessary for rationalisation of the process water system and distribution to the existing
and new consumers. An overflow collection tank and pumps shall also be installed at the existing
FGO concentrate thickener to feed overflow into the upgraded process water system.

Scheduling the installation of the new grinding thickeners and process water system shall ensure
that at least one unit is constructed and commissioned prior to the scheduled decommissioning and
conversion of the current grind thickener to the fourth CCD thickener.

5.3.4 Specific Requirements for FEED

5.3.4.1 General

The requirements of Front End Engineering Design (FEED) for the new grind thickening facility
shall be defined by ‘Appendix 

2A-1, General Requirements for Engineering Design’ and this Section
5.3.4.

5.3.4.2 Issues

Specific issues to be addressed during FEED shall include:

	 	•	 	Confirmation of the overall arrangement of the new grind thickening facilities;
	 
	 	•	 	Identification of a recommended tunnel design taking into account identified
settlement issues, constructability constraints and the project Community Engagement
Strategy;
	 
	 	•	 	Optimum construction staging methodology for the grind thickeners;
	 
	 	•	 	Construction plant and equipment requirements to facilitate installation of the

Equipment specifications, data sheets and bid packages to be developed during FEED shall cover the
following:

	 	•	 	Grind thickener mechanism;
	 
	 	•	 	Grind thickener tank;

the P&ID set identified in Section 2.2.

5.4 PRE-OXIDATION

5.4.1 Included Facilities

This Section 5.4 covers Facility 1342.

5.4.2 Background

The term “pre-oxidation” refers to the original intent of the circuit and has only survived in
name.

The pre-oxidation area currently contains three large tanks used to store thickened high grade ore
(HGO) feed for the pressure oxidation autoclaves plus a fourth storage tank of the same size which
holds flotation concentrate. This concentrate is blended with the HGO feed in the pre-oxidation
distribution box to target an optimal

			
	 	 	 
	MOPU-0011-02-C Appendix 2A-2 Technical Scope of Work
	 	Page 13 of 36

 

Table of Contents

 

sulphur grade in the autoclave feed of around 6.7%.

5.4.3 Upgraded Operation

The Feasibility Study identified the need for two additional feed storage tanks in the
pre-oxidation area complete with associated, agitators, slurry transfer pumps and an additional
distribution box. This was done to maintain the blended feed surge capacity ahead of the
autoclaves. It is intended that all equipment capacities match the existing system to allow
cross-over of duty if required. A new pipeline connecting the pre-oxidation area to the new
autoclave, complete with tie-ins to the pre-heaters, will also be required.

5.4.4 Specific Requirements for FEED

5.4.4.1 General

The requirements of Front End Engineering Design (FEED) for the Pre-Oxidation Area shall be
defined by ‘Appendix 2A-1, General Requirements for Engineering Design’ and this Section 5.4.4.

5.4.4.2 Issues

Specific issues to be addressed during FEED shall include:

	 	•	 	Identification of the most cost-effective tank foundation design to overcome
identified settlement issues;
	 
	 	•	 	Determination of the optimum construction methodology (‘stick build’ or
pre-fabrication) to suit site access constraints.

5.4.4.3 FEED Equipment Outputs

Equipment specifications, data sheets and bid packages to be developed during FEED shall cover the
following:

	 	•	 	Pre-Oxidation tanks;
	 
	 	•	 	Pre-Oxidation tank agitators;
	 
	 	•	 	Slurry transfer pumps.

5.4.4.4 Piping Outputs

Critical pipework connections to be designed during FEED shall comprise all pipes extending beyond
the P&ID set identified in Section 2.2.

5.5 PRESSURE OXIDATION

5.5.1 Included Facilities

This Section 5.5 covers Facility 1343.

5.5.2 Background

The existing pressure oxidation area comprises three 4.5m diameter (inside steel) x 31.2m tan-tan
autoclaves fed by six positive displacement pumps. Each autoclave is

			
	 	 	 
	MOPU-0011-02-C Appendix 2A-2 Technical Scope of Work
	 	Page 14 of 36

 

Table of Contents

 

capable of processing 13.5 t/h of sulphide sulphur under current plant arrangements.

The original plant design was based on a sulphide processing rate of 9 t/h through the three
autoclave vessels with three positive displacement feed pumps. Overall performance has been
improved over time with key upgrades including:

	 	•	 	Provision of an additional 12 t/h of oxygen supply (1999).
	 
	 	•	 	Installation of three direct contact heat recovery vessels (pre-heaters) to raise
the temperature of the feed and improve the heat balance (2001). The installed vessels
were very large and currently only one unit is required to maintain the required balance.
	 
	 	•	 	Installation of three additional positive displacement pumps with the primary aim of
improving pump reliability (2003).
	 
	 	•	 	Provision of an additional 10 t/h of oxygen supply and implementation of improved ore
blending capabilities to achieve optimal sulphide grade in the autoclave feed (2007).

The existing autoclaves also had major refractory lining failures in the first year of operation.
There were several reasons for this, but they boil down to an incompatibility between the design
of the autoclave vessels and the design of the refractory lining systems. The lining system was
altered and the operation has now had over 8 years of good refractory system reliability.

5.5.3 Upgraded Operation

The upgraded pressure oxidation facilities shall be located northwest of the existing autoclave
building and shall be similar in scope to one of the three existing trains, although with
generally larger equipment. Slurry feed piping shall pass along the southwest wall of the new
process building to the suction strainers.

The new facility shall comprise a 5.6 m (internal) diameter x 44.8 m tan-to-tan autoclave
operating under identical conditions to the existing autoclaves. The autoclave shall be fed with
two positive displacement pumps in the same duty/duty mode of operation as the existing
autoclaves.

The new autoclave shall be a carbon steel vessel lined by a corrosion resistant membrane and three
courses of acid brick. The corrosion resistant liner may be either lead, as used in the existing
autoclaves or a polymer based liner that has been used in some other POX autoclave operations.

Internally the new autoclave shall be arranged as the existing autoclaves are, but scaled in size.
This basic arrangement comprises:

	 	•	 	Six compartments with three sub-compartments in the first compartment;
	 
	 	•	 	Eight agitators — one to each compartment;
	 
	 	•	 	Oxygen, quench water and steam supply to every compartment.

Quench water, steam and oxygen shall be added into the bottom of the vessel directly beneath the
agitator.

High pressure steam will be supplied to a new steam blowback vessel which shall be located in the
new autoclave building. A cross connection shall be provided between the new blowback vessel and
the existing blowback vessel serving the original autoclaves.

Oxygen from a 70 t/h oxygen plant (by others) will be supplied to a new oxygen blowback vessel
which shall be located in the new autoclave building. As above, a

			
	 	 	 
	MOPU-0011-02-C Appendix 2A-2 Technical Scope of Work
	 	Page 15 of 36

 

Table of Contents

 

cross connection shall be provided between the new blowback vessel and the existing blowback
vessel serving the original autoclaves.

Quench water shall report to a 9.0 m diameter by 9.8 m quench water tank located outside the
southeast wall of the new autoclave building. High pressure quench water pumps shall distribute the
quench water to each of the autoclave compartments for temperature control and to the slurry
discharge pipelines for discharge flow control. Steam spargers shall also be provided to each
compartment for start-up heating or to assist with temperature control.

The autoclave shall be designed to treat 27 t/h of sulphur bringing the total pressure oxidation
capacity to 67.5 sulphur t/h — an increase of 67%. Due to the large throughput, the autoclave
discharge system shall consist of two parallel trains. Autoclave discharge slurry shall pass
through two separate 350 mm diameter discharge lines to two flash vessels identical to the
existing circuit flash vessels (5.5 m diameter x 7 m tan-tan). The pressure shall be let down via
a ceramic angle valve and fixed choke assembly of identical arrangement to but larger size (350 mm
vs. 250mm) than the existing plant.

Vapours from the flash vessels shall pass through two 3.5 m by 5 m quench vessels where sea water
is used to condense the vapour. The condensate from the quench vessels shall drain by gravity to
the oxidised residue wash circuit (Area 1349). Any vapour reporting to the quench vessel vents
shall pass through to two venturi scrubbers and then be emitted to atmosphere through a single
moisture trap and a vent stack. Condensate from the scrubber shall join the quench vessel
condensate stream.

A new flashed slurry collection and transfer system serving the entire pressure oxidation area
shall be provided as part of the upgrade works. Flashed slurry from the bottom of the two new
flash vessels shall drain to one of two 11m diameter by 8 m flashed slurry transfer tanks. Flashed
slurry from the existing three flash vessels shall report to the other flashed slurry transfer
tank. Oxidised slurry shall be pumped from these tanks to the two CCD oxidised slurry wash trains
(Areas 1345 and 1349) at equal rates.

The upgrade works shall also include a dedicated seal water system of similar design to the seal
water systems for the three existing autoclaves and a dedicated sea water quench water tank
complete with distribution pumps.

5.5.4 Specific Requirements for FEED

5.5.4.1 General

1 INTRODUCTION

The Lihir Gold group (LGL) is currently upgrading its operation on Lihir Island in the New
Ireland province of Papua New Guinea. The works, known as the Million Ounce Plant Upgrade (MOPU)
project, comprise the provision of additional pressure oxidation capacity together with a wide
range of ancillary process and utility services to facilitate increased plant throughput.

The purpose of this document is to define the specific Engineering inputs for design of
additional primary crushing and conveying facilities.

2 LIMITS OF WORK

2.1 GENERAL

This package of work shall comprise engineering design of all equipment, piping,
foundations, structures, access stairs and platforms and other associated works required for
implementation of the following:

	 	 	 	 	 
	Facility	 	Facility Name	 	Requirements
	1311

	 	Primary Crushing and
Conveying System No 1
	 	Modifications to
the existing primary
conveying facilities
to accommodate
provision of the
second primary
conveying system as
per Facility 1315
	 
	 	 	 	 
	1314

	 	Primary Crushing
System No 2
	 	Provision of
second primary
crushing facility
including crusher
discharge
conveyor.
	 
	 	 	 	 
	1315

	 	Primary Conveying
System No 2
	 	Provision of new
primary conveying
system from the second
primary crushing
facility to the
crushed ore stockpile,
including crossovers
to the parallel
existing conveyor
system.
	 
	 	 	 	 
	1316

	 	Ore Stacker No 2
	 	Provision of a
second radial stacking
conveyor at the
existing crushed ore
stockpile.

The services to be provided by the Consultant shall comprise execution of all activities
identified in the attached ‘Appendix 2A-1, General Requirements for Engineering Design’ including
engineering administration, Front End Engineering Design (FEED), detailed engineering design and
procurement support.

2.2 BATTERY LIMITS

2.2.1 General

The limits of work for this package shall be as follows:

	 	•	 	The design limits for piping, equipment and instrumentation shall be defined
by the following set of Feasibility Study P&IDs and the detailed piping /
equipment limits detailed in Section 9:

	 	 	 	130-FP-2001 Primary Crushing and Conveying, CR2001
	 
	 	 	 	130-FP-2002 Primary Crushing and Conveying, CV2202 to Radial Stackers
	 
	 	 	 	130-FP-2206 Fire Protection, Fire Water to Crusher CR2001

	 	•	 	General air and water service points shall be provided as per Section 2.2.3.

2.2.2 Interpretation of P&IDs

The P&ID’s identified in Section 2.2.1 and Section 9 are draft drawings produced out of the
Feasibility Study and shall be interpreted as follows:

	 	•	 	Equipment arrangements and equipment numbers shall be taken as given.
	 
	 	•	 	Pipe sizing and material specifications identified through the pipe labelling are
indicative only and shall be confirmed through design.
	 
	 	•	 	Valving arrangements are preliminary only and shall be amended as required
to meet specified isolation and control requirements.
	 
	 	•	 	Code ‘BL’ refers to a battery limit between different packages of work or
different facilities.
	 
	 	•	 	Code ‘Tl’ refers to a tie-in to an existing pipe or existing item of equipment.
	 
	 	•	 	Tie-ins have been shown where identified to date, but it shall be a
requirement of this package of work to determine the specific location and
details of all tie-ins required to complete the works.
	 
	 	•	 	Clouding reflects drawing changes made during the course of the Feasibility
Study design and does not necessarily reflect real physical changes to the
works. For the purposes of this package of work clouding on the drawings
shall be ignored.
	 
	 	•	 	The drawings have been marked up with tie-ins and battery limits reflecting
multiple packages of work. The Consultant shall only be concerned with those
limits identified in the following tabulations.
	 
	 	•	 	The ‘2000’ series drawings (eg 130-FP-2001) cover new upgrade works. All
other drawings are mark-ups of existing drawings describing the current plant.
	 
	 	•	 	The ‘0701’ tag included in the drawing number block shall not be read as an
integral part of the drawing number. As per the Project Reference document,
this tag merely identifies work in progress on a new drawing.
	 
	 	•	 	The drawing titleblock and the drawing titles currently shown in the titleblock
are not final. A separate data-base of proposed titles is available from LGL if
required.

Where any discrepancy that would affect design outcomes is identified between P&ID’s or between
the P&ID’s and other documentation, the matter shall be referred to the Project Manager.

5 TECHNICAL SCOPE

5.1 PRIMARY CRUSHING

5.1.1 Included Facilities

This Section 5.1 covers Facility 1314.

5.1.2 Background

The existing plant was designed with both a hard ore circuit and a soft ore circuit to treat
the spectrum of ore types identified in the Minifie and Lienetz deposits (at the time of this
original design, the Kapit ore body had not yet been discovered).

The hard ore crushing circuit consists of a 42” x 66” Fuller Traylor gyratory crusher which is fed
from a ROM ore bin via an inclined apron feeder. The bottom of the crusher is closed in with a very
minimal surge pocket and discharges directly on to the common discharge conveyor from both ore
circuits. On hard ore the crusher is capable of more than 1280 wet t/h, but as the ore clay and
moisture contents rise the crusher capacity drops markedly due to ore packing in the crusher and
adverse material handling properties.

The soft ore crushing circuit consists of a low speed rolls sizer which is fed from a small ROM
ore bin via horizontal apron feeder. The bin is designed to be fed by front end loader and is
equipped with a static grizzly with 600 mm centers. The gap is a specification of the sizer and is
a characteristic of the opposite rotation of the sizing
rolls and their size of nip. The crusher has processed up to 1000 t/h on soft materials but the
rate of throughput and reliability of the crusher drops rapidly as the ore competency increases.
The soft ore crushing circuit also discharges onto the common discharge conveyor.

During the most recent Flotation Expansion the transfer point from the common crusher discharge
conveyor to the overland conveyor was increased in height and size to allow the inclusion of a
secondary low speed rolls sizer. The purpose of the crusher is to reduce the F80 size to the SAG
mills in order to maintain throughput during periods of hard ore.

The existing crushing plant has a number of flaws that reduce capacity and availability, and
increase maintenance requirements.

The ROM bin has structural issues that have resulted in it being fed from the end opposite the
gyratory crusher when it was designed to be fed from either side. The inclined apron feeder is at
such a steep angle that it is difficult to maintain. It is equipped with a dribble conveyor but,
due to the angle and the wet weather conditions, the dribble often slides down the conveyor
creating a mud pile in the basement beneath the ROM bin which requires nearly continuous cleaning.

In addition, the gyratory crusher was installed with minimal clearance above the discharge
conveyor. As a result, crusher maintenance requiring the removal of the eccentric assembly
necessitates the dismantling of the discharge conveyor. Neither crusher can be utilized during
this type of maintenance.

The soft ore bin has also suffered structurally. The discharge apron feeder drive was underpowered
for the required duty and bin design. The low speed rolls sizer, while capable of design
throughput rates on soft ore has poor reliability and is used infrequently as a result.

Table of Contents

Plans are already in place for separate upgrade of the existing soft ore circuit in the first
half of 2008 to address the issues identified above. The ROM pad and soft ore bin will be
modified to accept Cat 777 haul trucks; the static grizzly sizing bar spacing will be increased
to 850 mm centers; and the MMD 750 low speed rolls sizer will be replaced with an ABON 10/220
CCTD low speed rolls sizer. The new sizer is designed to process the more competent ores at a
higher rate and with greater reliability than the original machine

5.1.3 Upgraded Operation

The upgraded plant requires provision of a second crushing facility complete with its own
overland conveyor, cross-overs to/from the existing conveying system, and a second radial stacker
at the existing crushed ore stockpile (COS).

The new crushing facility shall be located on dumped fill in the Harbour Base opposite the barge
loading facility as shown on Dwg 130-M-108. The facility shall be designed to accept ore passing
~900 mm from the mine, reduce it to a 100% passing 250 mm product (P80 ~ 110 mm) and convey it to
the new stacker.

The Feasibility Study outputs are based on separate hard ore and soft ore crushing circuits in a
configuration similar to that originally installed. This arrangement requires separate ROM dump
hoppers and apron feeders to a gyratory crusher and low speed rolls sizer, with separate
discharge conveyors to the overland conveying system. However, the alternative of a common
circuit comprising a single ROM dump hopper and apron feeder to two rolls sizers in series is
still considered an option, and shall be explored in more detailed during the FEED design as
outlined in Section 0.

Design throughputs for the two alternatives shall be as follows:

	 	 	 	 	 	 	 	 	 	 	 	 	 
	 	 	 	 	 	 	Peak	 	 
	 	 	 	 	 	 	Instantaneous

	 	 	2000	 	 	 	1400	 

The new crushing facility shall be designed to ensure that the issues associated with the existing
plant are not repeated. In particular:

	 	•	 	All ROM hoppers shall be designed to accept Cat 789 haul trucks.
	 
	 	•	 	Rolls sizers with greater tolerance of higher UCS feed shall be provided.
	 
	 	•	 	Should a gyratory crusher be provided for a separate hard ore circuit as in
Option A:

	 	o	 	The feed apron feeder angle for a gyratory crusher shall be
reduced to less than 15 degrees to reduce the operating and maintenance
problems associated with the existing feeder which has an angle of 22 degrees;
	 
	 	o	 	More elevation shall be provided between the discharge of a
gyratory crusher and the receiving conveyor to allow maintenance clearance for
the removal of the crusher eccentric without having to dismantle
the crusher discharge conveyor.

5.3 ORE STACKING

5.3.1 Included Facilities

This Section 5.3 covers Facility 1316.

5.3.2 Background

The existing crushed ore stockpile (COS) is a radial pile fed from a fabricated steel
stacking unit which runs on a rail and slews over a 180 degree arc.

The radial stacker was originally designed to carry up to 1730 t/h of ore flow although
current capacity has been de-rated to ~1500 t/h due to structural deterioration. LGL
will separately be making repairs to the stacker during 2008 to restore or improve
upon the original design capacity. At the same time LGL will also be expanding the

Table of Contents

COS footprint to extend the available radial stacking area to an effective 270 degree
arc.

5.3.3 Upgraded Operation

Upgrade of the primary crushing and conveying capacity as per Sections 5.1 and 5.2
requires provision of additional ore stacking capability, and a new stacker with 2250 t/h
capacity shall be installed as part of the project. It shall have the same range of travel as
the existing stacker (180 degree slew) although the arcs of motion of two units shall overlap
by approximately 90 degrees as shown on the drawings.

Special attention will be required during design to safeguard against stacker collision.

The expanded stockpile will be served by two sets of new under-pile feeders serving both the
existing Flotation Grade Ore grinding circuit and a second High Grade Ore grinding circuit.
However, design of these facilities is outside the scope of this package of work.

	Cyclone Overflow:

	 	MMC-5AB composite at 45% solids yielded ~ 2.5Pa, actual density will be lower, 2 Pa is a safe value
	Thickened Clave Feed:

	 	MMC-5AB composite, 55% solids
	Unthickened Clave Discharge:

	 	MMC-5AB composite, 36% solids, 67°C
	Thickened Clave Discharge:

	 	No test data available, assume viscosity similar to thickened clave feed but at lower density of 50% solids
	CIL:

	 	MMS-5A composite, limed to pH 10.5, 32.5% solids

	3.1	 	General

As part of the preparation of the capital estimate and control budget for the plant, CLIENT
requested Lycopodium to investigate several scope reduction options that would reduce the overall
capital cost. These options basically included reducing the CIL residence time by not installing
additional tanks, and reducing the overall plant throughput.

A report on these options and their impact upon capital cost and plant recovery was prepared and
issued to CLIENT for consideration.

The design and procurement for items that could be affected by these changes is already well
advanced, and CLIENT have requested Lycopodium proceed with the current design scope.

An indicative capital cost for the installation of a gyratory crusher in front of the existing jaw
crusher to handle oversize was issued to CLIENT for information. No further action is required
from Lycopodium on this issue at this point in time.

	3.2	 	Process

Approval of the following key design documents remains outstanding from CLIENT:

	•	 	3010-PDC-001 Rev D — Process Design Criteria
	 
	•	 	3010-PCP-001 Rev B — Process Control Philosophy (entire plant)
	 
	•	 	3010-PCP-003 Rev A — Process Control Philosophy — Three Stage Crushing Circuit
	 
	•	 	Crushing Area P&IDs:

	 	o	 	3010-P-1002 Rev F
	 
	 	o	 	3010-P-1025 Rev D
	 
	 	o	 	3010-P-1026 Rev D

Detailed design is proceeding based on these key documents, but formal review and approval from
CLIENT would be appreciated. CLIENT approval is particularly necessary for the crushing circuit
control philosophy and P&IDs for which Lycopodium do not have any process design responsibility.

P&IDs for the entire project have been updated during the period to include instrument numbers.
These are being progressively revised as vendor data is received.

Revision C of the control philosophy for the elution circuit is being prepared to incorporate
issues discussed with CLIENT at the HAZOP and will be issued during July.

	3.3	 	Mechanical / Piping

Revision E of the Equipment List has been issued and was the basis of the capital estimate.
Revision F is currently being updated to include drawing numbers for platework items and to
incorporate vendor information as received.

Single line Drawings AFC for the entire plant are underway and will be complete in July for
issue to the MCC supplier.

MCC tender was issued, received, evaluated and recommended for award during this reporting period.

A load study evaluating the ability to start the large loads within the expanded plant has been
completed and issued to CLIENT. This indicates that the voltage drop when starting the new mill is
only just within acceptable limits.

CLIENT have purchased a 10.8MW diesel power station. Lycopodium is awaiting confirmation from
CLIENT regarding the requirement to complete a load study to incorporate this power station.

HV switchboards specification was revised and re-issued. Tenders have been received and are being
evaluated.

A list of HV and VSD cables has been prepared ready for issue for tender.

Schematic drawings have commenced and will be ready for issue to the MCC supplier in line with
their fabrication schedule.

A Procurement Tracking Report is attached in Appendix 4.1.

	4.3	 	Expediting

An equipment delivery schedule is attached in Appendix 4.2.

Some equipment items are now ready for delivery (eg. 5012 — Air Diaphragm Pumps and 5023 — Solution
Agitators). These are being held at the vendor’s premises until such time as the logistics
contractor is engaged and the items can be delivered to site.

	4.4	 	Supplier Issues
	 
	4.4.1	 	5028 — Strip Solution Heater — Thermal Electric Elements

The control panels for the strip solution heaters were manufactured by TEE’s subcontractor without
incorporating the necessary control features that were agreed prior to award.

A meeting held at the subcontractor’s premises, has resulted in a rectification plan being agreed
upon. This will require some rework, and the costs of this rework are being borne by the supplier.
It will, however result in a delay to the agreed delivery date. This is being actively expedited.

	4.5	 	Areas of Concern

Significant delays are being experienced in receiving some purchase orders from CLIENT. In
some instances (eg. 5014 — Centrifugal Pumps), it has taken over a month from the issue of a
recommendation to receipt of a CLIENT purchase order.

If this continues, there is significant potential to impact upon the overall project schedule.

The HV switchboard specification has been revised based on a separate switchboard (supplied by
others) and re-issued for tender. This tender is currently under evaluation.

The forecast date for first ore into the new mill remains unchanged from last period at 27
April 2009.

Practical completion date has been brought back from 15th May reported last period to
20th April 2009. This is due to the staged manufacture and delivery of the intertank screens.
Alloytech have agreed on a staggered delivery schedule for the intertank screens, with priority
on the screen support frame and discharge pipes for the existing tanks.

The current summary and detailed project schedules are included in Appendices 6.1 and 6.2,
respectively.

A schedule has been received from JIP for the crushing plant. This indicates that cold
commissioning of the crushing plant is due to commence on 26 November 2008. The delivery of the
crushing area MCC (scheduled to arrive on site approx mid January 2009) will prevent this
forecast date from being achieved.

	6.2	 	Schedule Concerns

The delivery of the crushing area MCC will prevent commissioning of the crushing facility in
line with the schedule currently issued by JIP. The delivery of the crushing MCC has been
prioritised, but is still 16 weeks from date of order to ex-works delivery.

HV Switchboards are currently on the critical path. This is due to the re-tender of the package as
described in the procurement section. HV Switchboard tenders are currently under evaluation and
there is some possibility that currently forecast delivery time of 26 weeks may be improved upon.

Notes:

	 	1.	 	The budget has been set at the value of the capital estimate sent to CLIENT in June and includes
costs controlled by Lycopodium and costs controlled by CLIENT. This is yet to be approved by CLIENT
as the baseline budget for the project.
	 
	 	2.	 	The current forecast for the CLIENT controlled costs has been set at the current budget value in the
absence of any better information.

This is the first month for which a budget value has been reported, due to the capital estimate being
completed and issued to CLIENT for review and approval during June.

We are currently forecasting an under-run to the approved budget of.

The main components contributing to this variance are:

	•	 	Package 7002 — HV Switchgear is forecast to over-run the budget by approx  based on tenders received and currently under evaluation.
	 
	•	 	Package 7005 — LV MCC’s is forecast to under-run the budget by approx based on value recommended for award plus a growth allowance.
	 
	•	 	A forecast under-run in Lycopodium’s EPCM  contract of approximately based on the current reforecast of manhours remaining.

The Lycopodium controlled  contingency value is which is unchanged from the original budget figure
and represents of the forecast amount yet to be committed.

Note that all changes submitted to date are for the EPCM costs only, as the direct budget had not
been established. Now that a direct cost budget has been established, all future change notices will
consider both EPCM and direct costs.

7.5 EPCM Costs

EPCM costs are contained within the overall cost report provided in Appendix 7.1 and are summarised
in Table 7.4 below.

Table 7.4 EPCM Costs (USD)

	 	 	 	 	 	 	 	 	 	 	 	 	 
	 	 	Current	 	Current	 	Budget	 
	Area	 	Budget (1)	 	Forecast	 	Variance	 
	EPCM Costs
	 	 	 	 	 	 	 	 	 	 	 	 

Note that the current budget exceeds the current commitment value in Appendix 7.1 by USD
158,566. This is due to the current budget including an allowance for escalation due to rate
increases post June 2008. A change notice will be submitted in July to rectify this discrepancy.

Table 7.4 below provides the status of the EPCM manhours for the project.

Notes: 1. This table excludes hours for Electrical and Instrumentation Design and Drawings

The total forecast EPCM hours of 44,559 is an increase of 1,432 manhours from that forecast last
period.

The main factors contributing to this increase in forecast manhours are:

	•	 	Allowance for Peter Baako (HSE advisor) to mobilise to site early to assist CLIENT with their operations. This will be the subject of a future change notice.
	 
	•	 	Have allowed additional drafting hours to be consumed in the Manila office. Whilst this results
in an increase in total manhours, it also results in a decrease in EPCM costs.
