RECITALS:

	A.		On 26 April 1995 pursuant to the Mining Act 1992, the Landowners, the Lihirians and LGL through its agent Lihir Management Company Limited (as it was then) entered into the IBP which formed the all encompassing compensation package for the Landowners and the Lihirians.

	B.		All of the agreements, undertakings, commitments and the spirit of the original IBP are valid and remain in force until and unless amended by the Revised IBP or any other subsequent agreement.

	C.		The IBP became due for review on 26 April 2000 Negotiations between the Parties with LMALA and the NRLLG represented by the Joint Negotiating Committee or JNC) began on 20 June 2001. The Revised IBP embodies the consensus reached by the Parties on each of the issues discussed. All of the issues discussed are captured in the five chapters of the Revised IBP.

	D.		It was recognised and acknowledged by the parties at the beginning of the review process that the opportunity should be taken to re-orient the commitments under the IBP so as to bring them into line with the circumstances now prevailing on Lihir, in particular insofar as impacts on the community are concerned. Accordingly the Revised IBP describes the changes to the provisions of the IBP and new commitments required to address long term community development and sustainability on Lihir.

	E.		During the course of the review the JNC developed a policy document titled the Lihir Sustainable Development Plan (LSDP). The NRLLG and LMALA have proposed and LGL has accepted and agreed that the LSDP should form the basis for the revised IBP and provide the framework pursuant to which all future development initiatives are to be aligned and focused over the life of the project.

	F.		The parties and all other stakeholders agree that the LSDP must be implemented through the legitimate agency of government, (the NRLLG). Under the decision by the Tumbawinlam Assembly dated 30^th September 2004, (Resolution Number 37/2004, attached to this Agreement as Appendix A), NRLLG has assumed ownership and responsibility for the implementation of the LSDP.

INTEGRATED BENEFITS PACKAGE – PROJECT MANAGEMENT

	G.		The Parties acknowledge that this Agreement is a starting point and as such signifies a commitment to a process and a series of Programmes, each of which still requires considerable detailed planning and budgeting work to attain the development objectives set out in the LSDP.

	H.		The Parties acknowledge that one of the core elements of sustainability in Lihir is the development of the capacity of the institutions required to implement the LSDP, in particular the NRLLG and the Nimamar Special Purposes Authority (NSPA) and the Parties have accordingly agreed that a capacity building Programme shall be a major initiative under the LSDP.

	I.		The JNC has expressed a desire to investigate alternative financial structures that will provide for more Lihirian control of their own affairs and that will utilise funds provided under existing agreements from LGL to generate investment returns as well as meet the annual budget needs of the Lihirians. LGL has agreed to work with the Lihirians to identify various options and possibilities, subject always to the requirements of the laws of PNG, good governance and commercial viability for all parties.

	J.		The IBP provides for a review each five years from the date of the original agreement. The parties hereby acknowledge that the next review will take place five years from the date of this agreement.

While the longer term aim is to hand over the implementation of these programmes to the NRLLG and its agencies, it is acknowledged that this will take some time to achieve and that the NRLLG and its agencies need to implement the various capacity building programmes before they can take over all of the functions currently being implemented by LGL.

(b)		The LSDP spreadsheets in Appendix E identifies the programmes and projects to be carried over, and LGL undertake that it will continue to implement all such continuing projects and programmes as projects carried over in the Revised IBP, until such time as the parties agree to a mutually convenient hand over. LGL will

INTEGRATED BENEFITS PACKAGE – PROJECT MANAGEMENT

		fund these activities directly out of the K100 million total funding provided under this Revised IBP and referred to in Clause 3(a). LGL will follow the process established for accessing funds from the IBP and will account for its spending on these continuing projects to the FEC as part of the quarterly review process.

19.		Chapter 1 Budget

(a)		The Chapter 1 LSDP spreadsheet in Appendix E(1) identifies the programmes and projects to be budgeted for implementation under Chapter 1.

(b)		NRLLG undertakes that it will under its capacity building programme referred to in Clause 16 of this Agreement, provide for Ward budget coordination so as to assist Ward members to formulate and implement their respective Ward budgets.

20.		NRLLG Undertakings

(a)		Subject to Clause 12(c) of this Agreement, NRLLG agrees that it shall do all things necessary to ensure that the LSDP is successfully implemented.

(b)		Consistent with (a) above, NRLLG undertakes that before the end of 2007 and for each of the financial years to and including the year ended 31 December 2010, it shall consolidate its budget and the LSDP budget into a single budget that will be implemented through the Lihir Sub-District Treasury Office, or any other alternative accounting system which is consistent with the Public (Finances) Management Act and which is agreed to by all the Parties, where the establishment of the Lihir District Treasury Office is delayed.

(c)		NRLLG undertakes that where it does not have the expertise to implement any part of the LSDP it shall request non-financial assistance from the parties to this Agreement and the Parties agree that where a request for assistance is requested by NRLLG they shall use reasonable endeavours to assist NRLLG, provided always that such assistance does not include financial assistance.

(d)		The Parties all acknowledge that the Parliamentary Committee structure of the NRLLG needs to be activated to take charge of sectoral policy development and that all external assistance, whether from LGL, the national government or any other source, must be directed into programmes and projects through this committee structure. Accordingly, all projects and programmes of social monitoring, as referred to in Chapter Two of the IBP under the sub- heading Human Development’ will be directed through the appropriate parliamentary committee as determined by the NRLLG. The proposed Office of Social Monitoring will also be a sub committee of that body and will report to it.

(e)		NRLLG undertakes, and the parties all agree, that the annual expenditures of the NRLLG must be audited by a privately commissioned audit firm independently of any audit which may be carried out by the national government or the Auditor General’s office. Any such audit report is to be made available publicly, including to the other parties to this Agreement, as part of the NRLLG commitment to transparency and accountability to the people of Lihir.

CHAPTER TWO: DESTRUCTION

21.

LMALA-Implementing Agency

The lead agency for implementation of Chapter Two programmes is LMALA. All compensation payments provided for under the Revised IBP will continue to be paid by LGL from within the total amount allowed and referred to in Clause 3(a) of this Agreement. These payments will be reported to the FEC and included in the quarterly financial reports and the Chapter 2 budget as set out in the IBP.

22.		Affected Areas

(a)		The IBP identified the following as areas of Lihir that would be subject to more significant impacts from mining operations.

	(I)		Putput 1 and 2

	(ii)		Londolovit Village

	(iii)		Kunaye Village

	(iv)		Zuen Village

	(v)		Lipuko Village (by virtue of the Putput Community Agreement)

(b)		It was agreed that these areas should receive additional benefits in the form of the following infrastructure development:

		Reticulated water Garbage collection and septic tank emptying facilities Assistance with preparation of village layout planning Housing assistance Electricity reticulation

(c)		Initial housing assistance was provided to the identified communities in the form of a lump sum payment under the IBP. Thereafter, an annual payment was to be made into trusts established for this purpose, based on the area of lease land contributed by each of the following communities to the project. The annual payment is based on the Damaged Land rate of land use by the area of leases:

	(I)		Putput 1 and 2 as covered in the Putput Community Agreement

	(ii)		Londolovit K75, 000.00

	(iii)		Kunaye K75, 000.00

	(iv)		Zuen K50, 000.00

		These payments were activated at the time the project impacted on the relevant communities. In the case of Zuen this would only be triggered by commencement of a limestone quarry project which has not yet eventuated and may not eventuate. No specific provision was made for the Kapit community which is covered by a separate but related agreement, the Kapit Relocation Agreement.

(d)		The Parties acknowledge that the Malie Community was accorded “Affected Area” status by virtue of the Memorandum of Understanding between LMC and the Malie Community dated 3^rd May 2001.

(e)		The Parties hereby acknowledge and agree that the list of “Affected Area” communities shall be redefined as

INTEGRATED BENEFITS PACKAGE – PROJECT MANAGEMENT


Putput 1 and 2	-	Most Affected community
Kapit village	-	Most Affected community
Londolovit village	-	Affected Area community
Kunaye 1 and 2	-	Affected Area community
Malie Island	-	Affected Area community
Zuen	-	Lesser Affected Area community
Lipuko	-	Lesser Affected Area community

(f)

These areas shall therefore continue to receive extra benefit in the form of infrastructure development through the VDS Grants scheme with particular, but not exclusive, emphasis on:

	(a)		Reticulated water

	(b)		Garbage collection and septic tank emptying facilities

	(c)		Assistance with preparation of village layout planning

	(d)		Housing assistance

	(e)		Electricity reticulation

Recognising the specific issues and the specific needs of the “Affected Area” communities, the Parties have agreed that the project matrix annexed herewith as Appendix G to this Agreement shall be implemented under the supervision of LMALA. The Parties agree to provide whatever logistical and technical support from existing resources they reasonably can to assist LMALA to perform this task.

23.

General Compensation

The Parties acknowledge and agree that the Land, Crops, Water and Air Compensation Agreement shall be amended by replacing the old Land Use Rates and Economic Trees Rates with the revised rates as per the tables annexed hereto as Appendix H(1) and H (2).

24.

Alignment with the LSDP

The Parties:

	(a)		acknowledged that the beneficiaries of the projects and programs under Chapter 2 now totally depends on goods and services provided by LGL which in the long term is not sustainable and therefore inconsistent with the principles of the LSDP;

	(b)		acknowledged and agree that the projects and programs under Chapter 2 shall be approached in a manner that will cause a shift from the dependency and reliance mind set currently being encouraged by LGL to a self help mind set based on the principles of the LSDP;

	iv.		Financial Independence Project- to ensure that each individual in the Affected Areas is assisted (by following a definitive financial plan tailor- made for his needs) to convert from being a liability to an asset to himself, his family and to his community;

(d)

agree and accept that they will jointly work together to ensure that:

	i.		the required details, resources and requirements necessary and required to successfully implement the four programs described in paragraph (c) above are completed;

	ii.		these four projects are progressively and constantly improved in line with the objective of achieving the Lihir Destiny; and

	iii.		more projects and programs (in addition to these four projects) shall be developed to ensure that the shift envisaged in paragraph (b) is realised and the attainment of the Lihir Destiny is achieved;

(e)

Subject to paragraph (c)(i) above:

	i.		The Parties acknowledge that there is a need for LMALA to re-organise and re-orient itself in order for it to be in a position to deliver the outcomes it has set itself for the period of the LSDP. This process will be conducted as part of the capacity building exercise referred to in chapter one of the LSDP.

	ii.		LMALA agrees that it needs to duly gain a mandate from its stakeholders according to its constitution to endorse the revised structure and its operational role.

25.

Financial Support for LMALA

LGL, NRLLG and LMALA commit to a process of jointly resolving the issue of financial support for LMALA, as a result of the changes and to formalise this into a single project under the NRLLG budget. This is in line with LGL’s considerations.

National Government (the State)

New Ireland Provincial Government (NIPG)

Lihir Gold Limited (Lihir)

RECITALS:

	A.		On or around 26 April 1995, Lihir Management Company (LMC) acting for and on behalf of Lihir Gold Limited (LGL), Nimamar Development Authority (predecessor to NRLLG) and LMALA entered into an agreement known and referred to as the Integrated Benefits Package (IBP). The IBP contained all of Lihir’s agreements with, and commitments to, the Lihirian community, as well as a series of Memorandum of Agreement between the landowners, the local and provincial level governments and the State.

	B.		The IBP provided for review by the parties of the commitments in the IBP after a period of five years had elapsed.

	C.		The review process has been undertaken involving the Joint Negotiating Committee (JNC) representing NRLLG and LMALA on behalf of the Lihirian community, LMC for and on behalf of Lihir and representatives from the National Government and from the NIPG. The first formal meeting of all stakeholders took place at the Lihir Hotel in June 2001 .

	D.		Discussions have proceeded on a regular basis since that date and as of the end of 2004 had reached a point where significant unresolved issues had prevented further progress.

	E.		On 20^th April 2005, the Minister for Mining sent a letter to the President of the NRLLG setting out proposals for the JNC, SML landowners and Lihir to consider to progress conclusion of the IBP review (“the proposals”). A copy of this letter is attached as Schedule A.

	F.		On 24 April 2005, the Chairman of Lihir sent a letter to the Independent Chairman of the IBP Review process, Mr Brown Bai, setting out the terms of Lihir’s final offer made to NRLLG and LMALA in a meeting conducted on Lihir on 23 April, 2005 (“the offer”). A copy of the offer is attached as Schedule B.

	G.		On 26^th August 2005, the JNC presented its response at Kokopo, ENBP to the proposals and this JNC response was confirmed by letter dated the same day, a copy of which is attached as Schedule C.

	H.		On 8^th September 2005, Lihir sent a letter to the Independent Chairman of the IBP Review process, setting out its response to the JNC. This was

Page 1

			accompanied by a draft Status Statement which was modified on 13^thSeptember 2005. A copy of this letter and the modified Status Statement is attached as Schedule D.

	I.		On 23^rd September 2005, the National Government sent a letter to the President of the NRLLG and the Chairman of the JNC setting out it’s response to the JNC Kokopo presentation. A copy of this letter is attached as Schedule E.

	J.		By this document therefore the parties wish to confirm their understanding of the status of the various proposals, offers and responses and establish the steps to be undertaken to finalize the review process and enter into a final, detailed revised IBP agreement to allow for the implementation of commitments.

As at the date of this document the positions of the parties are as follows:

Lihir Gold Limited:

The total financial commitment of Lihir under the IBP, for the period of five years from execution of formal agreements by Lihir and the JNC, shall consist of a total of:

	(a)		K100 million, less agreed sums already expended in relation to the review process. These funds are to be directed to the implementation of the Lihir Sustainable Development Plan [LSDP] as developed through the IBP Review process and as may be endorsed by the parties thereto;

IBP TRSUST ACCOUNT PROCEDURES

Rules for Accessing LSDP Funds

Introduction

Annual funding under the revised Integrated Benefits Package (IBP) is allocated annually to fund projects and programs classified under five chapters of the Lihir Sustainable Development Plan (LSDP). Programs and projects under the first four chapters of the LSDP are planned for and administered by various Lihir Institutions, while the fifth chapter contains allocation to various landowner Trust Funds currently administered by Lihir Gold Limited. Whilst a number of institutions are involved in the implementation of the LSDP the process by which each of these institutions must follow to access funding shall be consistent with the Public Finances (Management) Act 1995.

The rational is all parties to the revised IBP agree that annual funding provided by LGL to the Lihir community in line with the revised IBP shall be treated in the same manner as public funds. Having said this, all parties endorsed that LSDP projects and programs that require funding under the revised IBP must be submitted annually by respective institutions to the NRLLG for consideration prior to annual planning and budgeting process. The LSDP Planning and Monitoring Committee shall review and sign off on the project documentation to ensure such projects and programs are in line with Lihir destiny concept before they are submitted to the NRLLG for approval and budget consideration.

The purpose of this document therefore is to outline this process so that each of these institutions, the NRLLG, LGL and most importantly the Lihir community is aware and understand this process.

Planning

Institutions responsible for each chapter shall ensure that all programs and projects are identified through a consultative process and plans are endorsed by an appropriate committee responsible for planning and implementing such projects and programs. Such committees include the Law & Order committee, Health Committee, Education Committee, Media Committee and other such committee established under the NRLLG. The exception will be chapter two and chapter four of the LSDP which are administered by LMALA executive and the Board of Directors of LSDP Ltd respectively. Such committees and institutions are referred to in this text as Project Owners.

Projects owners must prepare a project formulation document for each project or program identified using the approved Project Formulation Documentation Form (PFD). It is the responsibility of the project owner to submit PFD to the Sub District Administrator or Chairman of LMALA to sign off before submitting the same to the

LSDP Planning & Monitoring Committee for review. The LSDP Planning & Monitoring certifies that the project or program is in line with the LSDP concept before the documents are submitted to the NRLLG through its Finance Executive Committee for deliberation and approval. Submitted PFD documents that are not in line with the Lihir destiny concept will be referred back to the project owner.

Budget

Whether these projects and programs make it to the budget is a decision that will be made by the NRLLG based on expected revenue and Government priorities for the coming year. A copy of the NRLLG Budget shall be made available to the District Treasury and the LSDP Board of Trustees once the budget has been through the approval process.

Tendering

Consistent with the Public Finances (Management) Act 1995, any projects and or services that exceed certain levels of expenditures shall go before the appropriate tender board. The responsibility for administering the tender process rests with the Nimamar Special Purpose Authority (NSPA). Budgeted projects or services that fall within levels of authority where it needs to go on tender will not be funded until such time that the tender process has been completed.

Implementation

The Board of Trustees is a representative board responsible for administering the LSDP Trust (Investment) account. By Agreement Lihir Gold Limited is committed to paying K1.67 million a month to the LSDP Trust (Investment) account. As soon as the NRLLG annual budget is approved a copy of the budget must be submitted to the Board of Trustees who will deliberate on how the budget is funded. The Board of Trustees shall meet on a quarterly based to decide on release of funds to the LSDP trust account administered by the District Treasury Office where funds will be accessible to project owners to fund approved projects.

The establishment of the District Treasury Office is appropriate to provide the necessary financial system required by the NRLLG and the District Administration to streamline the management of these annual grants within the Government system. Additionally the installation of Government Accounting System (PGAS) in proportion to the trust instrument and instil financial management regulations consistent with the Public Financial Management Act will enhance efficiency and effective management of peoples funds. The District Treasury as required under the trust instrument is obligated to provide monthly and annually bank reconciliations and statements of receipts and payments as directed.

Monitoring

The LSDP Planning and Monitoring Committee is a representative body set up specifically to ensure that all projects and programs recommended for funding are in line with the LSDP and that funds allocated are spent only on these projects and programs and not redirected to expenditures deemed inconsistent to the Lihir destiny.

DATE 28 March, 2003

PARTIES

The Independent State of Papua New Guinea (“State”) (represented by the Department of Treasury and the Department of Mining)

Nimamar Rural Local Level Government (“NRLLG”) (as representatives of the Lihirian Community)

Mineral Resources Development Company Limited (“MRDC”)

Mineral Resources Lihir Limited (“MRL”) (as trustee of the Deed of Settlement — Lihirians Equity Trust dated 14 August 1997 between Robin Moaina CBE as Settlor and MRL as Trustee)

Lihir Mining Areas Landowners Association (“LMALA”) (as representatives of the Lihir Mining Affected Areas)

Lihir Management Company Limited (“LMC”) as agent for and on behalf of Lihir Gold Limited (“LGL”)

BACKGROUND

A.		MRL holds 77,169,431 ordinary shares in LGL (representing 6.76% of the issued share capital) which are held on trust for the beneficiaries under the Lihirian Equity Trust, who are Lihirian landowners.

B.		MRL financed its acquisition of shares in LGL during 1995 using funds borrowed by MRDC from European Investment Bank (“EIB”), which were on-lent by MRDC to MRL , details of which are included in an On-lending Agreement dated 12 July 1996.

C.		In the absence of dividend income MRL has not made repayments of principal or interest of its loan from MRDC.

D.		MRL has not met its management fees and associated administrative costs accrued to MRDC.

E.		Notwithstanding the non-payment referred to in paragraph C, MRDC has (with the approval of and assistance from the State) made repayments of principal and interest due to EIB.

F.		A Joint Negotiating Committee was established, consisting of representatives of LMALA and NRLLG as representatives of the Lihirian Community, for the purpose of negotiating with the State and LGL the review of the Integrated Benefits Package Agreements (“IBP”).

G.		During the review of the IBP, the issue of Lihirian equity and the settlement of the EIB loan became a significant issue which was beyond the scope of the State/LGL IBP Review Team to resolve. A special LGL Board subcommittee, the Secretary of the Department of Mining and representatives from MRDC and the Department of Treasury have been involved in discussions towards a resolution of the equity issue since March 2002.

H.		At a meeting in Kokopo on 14 January 2003, the JNC discussed a proposal to sell down MRL equity to a minimum 5.2% conditional upon 6 conditions being met.

I.		A Special Working Group (“SWG”) was established to address the implementation of the 6 conditions of the JNC’s acceptance of the equity sell down as described in the letter from the State and LGL to the JNC of 28 January 2003. The SWG comprises representation from the JNC, LMC, Department of Mining, Department of Treasury, MRDC, and an independent Chairman.

J.		The JNC responded to the Minister for Finance & Treasury, the Minister for Mining and the Chairman of LGL on 3 February 2003 outlining the JNC’s understanding of the State and LGL position on acceptance of the 6 conditions.

K.		Funding will be made available to establish an investment fund out of which future instalments of principal and interest shall be made directly to the EIB, subject to agreed modification or removal of the on-lending agreements and charge over the remaining MRL equity.

PRINCIPLES AGREED

1.		OWNERSHIP, ESTABLISHMENT AND MANAGEMENT OF INVESTMENT ACCOUNT

		Subject to any requisite regulatory approvals by the Bank of PNG, a Euro denominated bank account will be established in the name “MRL-Lihirian Investment Account” for the proceeds of sale referred to in clause 2 (“Investment Account”). This bank account will be managed by an investment account committee (“Investment Account Committee”) which comprises one representative from each of:

	•		MRL;

	•		MRDC; and

	•		LGL.

2.		SELLDOWN OF MRL EQUITY

		On the basis of satisfactory exchange rates and share price, MRL will sell down its equity in LGL to a level no less than 5.2% of the total equity and:

	•		the sale price and arrangements for doing so will be co-ordinated by MRL and MRDC;

	•		MET, will seek to obtain the best price obtainable to sell the relevant shares;

	•		the net proceeds of sale will be converted into Euros and paid to the credit of the Investment Account; and

	•		The Investment Account Committee can only use funds to service the loan and when the loan is discharged any residual funds must go to an account managed by MRL on behalf of the Lihirian community in accordance with the trust deed as amended.

3.		STATE/ MRDC GRANT

		The State and MRDC agree to write-off and release MRL:

	•		from 100% of liability in respect of interest payments made by MRDC to EIB prior to 15 December 2001;

	•		from 100% of liability in respect of the principal and interest repayment made to EIB in December 2001;

	•		from 50% of liability in respect of the principal and interest repayment made to EIB in December 2002; and

	•		from 100% of liability in respect of management fees and associated administrative costs incurred to MRDC prior to the establishment of the Investment Account,

		totalling PGK19,151,518.00.

		It is acknowledged that the State and MRDC will meet to address the internal accounting issues with respect to the December 15, 2002 principal and interest payment and associated costs.

4.		LGL COMMUNITY SUPPORT GRANT

		LGL will give MRL amounts of money to be applied as follows:

	•		PGK3,532,759.00, (which MRL directs be paid to MRDC), representing 50% of the debt incurred by MRL to MRDC resulting from the repayment made to EIB in December 2002; and

	•		US$2,635,000 to be paid into the Investment Account,

(“Community Support Grant”)

		The purpose of the Community Support Grant is to assist MRL and the Lihirian Equity Trust to be financially self sufficient in respect of the repayment of its loan from MRDC, and is given in recognition of the importance of the Lihirian Community in the success of the Lihir mine. Payment of the Community Support Grant in to the Investment Account will be made as soon as practicably possible after the sale of the MRL shares and transfer of the proceeds in to the Investment Account.

		Interest will begin to accrue on all amounts (sale proceeds and Community Support Grant) from the time they are deposited in to the Investment Account.

		In the event that MRL sell down its equity in a number of tranches, payment of the Community Support Grant will be made in to the Investment Account at a percentage equal to the percentage of MRL shares sold and the proceeds of which are paid in to the investment account. At the time that MRL has sold sufficient shares to meet the needs of repayment of the loan, LMC will make payment into the Investment Account any residual amount remaining of the Community Support Grant.

		In addition, LMC will pay the amount of interest in to the Investment Account to a level that would exist if the entire Community Support Grant was paid in to the Investment Account at the time the first MRL shares were paid in to the Investment Account. The interest rate used by LMC will be that rate applied by the bank to the Investment Account.

		The amount of interest must be calculated on the sum of the total Community Support Grant and the proceeds of the sale from MRL’s shares in to the Investment Account.

		For completeness, the amount of additional interest LMC will contribute to the Investment Account is calculated as follows (on the date of each sale of shares):


		(US$ 2.635 million — LP) x IADIR x NDSLS

where:

LP	=	LMC payments already made into Investment Account;

IADIR	=	Investment Account daily interest rate;

NDSLS	=	Number of days since last share sale.

5.		NO DILUTION OF MRL EQUITY

		LGL and the State agree that MRL’s equity proportion of no less than 5.2% will not be diluted to a level less than 5.2% due to any need by LGL to raise equity in the Lihir project after the selldown referred to in paragraph 2 subject to the following matters:

	•		this obligation only applies to any mining activity, whether land or sea based, on the Lihir Group of Islands;

	•		this obligation does not apply to any new project outside Lihir Island, for example where the Board of LGL acquire a new mine or exploration rights outside the Lihir Group of Islands; and

•

implementation will be subject to obtaining any necessary approvals including, if applicable, approval from other shareholders.

6.		AMENDMENT TO EQUITY TRUST DEED OF SETTLEMENT

		The State (with the support of LGL) agrees that the Deed of Settlement — Lihirian Equity Trust be amended and varied to be consistent with general principles of the Lihir Strategic Development Concept and the Long Term Investment Fund (“LTIF”) to the extent possible by relevant law.

		Since this request will take considerable time to evaluate and bring into effect, the issues associated with changing the Trust Deed are to be dealt with by the SWG.

		Both the State and LGL are of the opinion that several issues in particular need to be fully addressed within the SWG including, but not limited to:

	•		good governance of the highest standard of the Trust and LTIF;

	•		no payment or benefit to individuals or select groups, specifically from the LTIF;

	•		funding of administration and management of MRL;

	•		details on the value and mechanisms for investment and draw down of the LTIF; and

	•		at the request of the Lihirians in a manner consistent with the new Trust Deed, the Trustees to be given the ability and authority to sell shares.

		Given the need to jointly communicate with the community the SWG will also be charged with the task of coordination of the content and delivery of community information programs regarding equity resolution and associated matters.

7.		LIHIRIAN REPRESENTATION ON LGL BOARD

		Working on advice from the JNC Executive, the SWG will develop a protocol for the nomination of one Lihirian representative to the Board of Directors of LGL, acknowledging that:

	•		this protocol will be subject to approval by the LGL Board;

	•		the appointment of any director is subject to approval by the shareholders of LGL in annual general meeting;

	•		LGL will consider any necessary amendment to the constitution of LGL to reflect such changes, subject to approval by the necessary majority of shareholders; and

	•		all directors are subject to periodic re-election in accordance with the constitution of LGL.

8.		LIHIR NON-MINING ACTION PLAN

		LGL and NRLLG will each initially contribute K50,000 per quarter to the Lihir Non-Mining Action Plan, provided that the total support (across the operational office,

		LMALA or any other representative organisation) does not exceed the current regular support payments and that the NRLLG are in agreement on the understanding that the operational, financial and other administrative arrangements will be detailed within the final IBP Review documents.

9.		PROJECT EXPANSION

		The Lihirian Community, LMALA, NRLLG and MRL support, in principle, possible expansion of the Lihir project, but only after all issues have been adequately considered, and relevant approval and consultative processes completed in a manner consistent with the principles of the Lihir Strategic Development Concept.

EXECUTIVE SUMMARY

THE LIHIR SUSTAINABLE DEVELOPMENT PLAN

1. Introduction

This is the executive summary of the Lihir Sustainable Development Plan (LSDP). The LSDP is the NRLLG’s Twenty Year Plan for the development of Lihir. Understanding the basic principles of the LSDP is fundamental to understanding how the K107million Revised IBP will be expanded over the initial five years of the LSDP.

2. Background-IBP

The IBP was agreed to on the premise that its implementation will result in the realization of the Lihir Dream.

(1) The Lihir Dream prior to the Lihir Project

Prior to the Lihir Project people were talking about the “Peketon” (wave), Lihir nitel a City”, “Da lo mon na mani”, “Aniokaka nitoi Ladolam”. This was the Lihir Dream.

(2) The Spirit of the IBP

The Lihir Dream formed the spirit of the IBP upon which the IBP was concluded. The spirit of the IBP was the following objectives:

(a)

Parallel Development

To ensure that development in all villages in Lihir will happen in parallel to the development of the Lihir Gold Project.

(b)

Balance Development

To ensure that development in Lihir is balanced in all villages and wards in Lihir.

(c)

Sustainable Development

To ensure that development in Lihir is sustainable. That is, that development in Lihir must be able to sustain itself without being dependant on the Lihir Gold Project.

(d)

Stable Development

To ensure that development in Lihir is stable. This must happen in harmony with the Lihir Society and not destroy and erode the order and culture that existed in the society prior to the operation of the Lihir Gold Project.

These objectives remained unachieved even though the project has been operating for 10 years. The LSDP was designed to achieve these objectives.

3. Lihir Sustainable Development Plan

The failure of the Existing IBP to achieve the four objectives referred to above was due largely to the fact that there was no clear plan that sets out how these four objectives would be achieved. As a result of the lack of having a plan for the achievement of the four objectives and more so the Lihir Dream the funds disbursed under the IBP were squandered or spent on projects and programs that directed development away from the attainment of the four objectives. Millions of Kina that were spent left Lihir because there were no systems set up to capture such money so that the money remains in Lihir to grow and fuel the growth and expansion of the Lihir economy. Moneys provided by LGL were all used to finance expenditure budgets that were not aligned to the attainment of the Lihir Destiny. This meant that money coming into the hands of Lihirians quickly went out again leaving Lihir in a cash poor position. Lihir remained a liability society. The diagram below shows this problem. The diagram to the left shows what is happening now where all we have is an expenditure budget where money comes in as income and all goes out again as expenditure. For us to align our income and expenditure to the attainment of the Four Development (Lihir Destiny) we must move away from a typical expenditure budget to a growth driven budget arrangement with the balance sheet showing asset oriented expenses as illustrated by the diagram to the right as shown below.

erroneously did not take ownership and control of the processes and systems required to successfully implement the IBP to realize the Four Objectives.

It is therefore critical that we realise that our actions has taken us towards the pathway of disaster which is now eminent and it is now critical that we accept where we are, make a decision to “U” turn and turn back and action that decision. The Revised IBP is designed to ensure that we make that turn and then follow the LSDP to lead us back to the attainment of the Four Objectives hence the attainment of the Lihir Destiny which is basically the Four Objectives.

The Revised IBP is designed to address the causes for the non attainment of the Four Objectives. To attain the Four Objectives, the Lihir people must have a clear destiny, a vision, goal and strategy on how to achieve the four objectives. The LSDP is designed to ensure the attainment of the Four Objectives through a deliberate 20 year plan. The LSDP sets out the destiny, vision, goal and strategy that we believed are required to ensure that the Four Objectives of the IBP is realized.

3.3 Focusing on the Individual’s Net-worth

The LSDP is focused on increasing the personal net-worth of each individual person in Lihir. This process entails changing his mind set by empowering him with the relevant knowledge wisdom and skill or giving him the opportunity (through the creation of a conducive environment) and then setting him free through entrepreneurial business development. This is a process and wiil be done in line with the Success Formula illustrated below:

Holistic Human Development = Empowerment of the People.

Positive Development requires a certain mind set. A mind set of “I can, mi nap”. In Lihir every one is waiting for some one else (LMC/LGL, NRLLG, Provincial and National Government) to create a better life for them. People do not realize that they only have themselves to be blamed for the poor situation they are in. The Lihir Destiny is the destiny of every individual Lihirians and families. Accordingly, the first task is to equip (empower) each and every one of them with the right mind set. This process will be addressed by the Holistic Human Development Program. That is why it is the focus of the initial five years. Accordingly, all the priority projects and programs under the Revised IBP must be geared at addressing Holistic Human Development.

Economic Development for Communities = Giving the People the Opportunity.

Once the mind set has been changed and the people have acquired and practice the “I can, Mi Nap” mentality and attitude, the next process that must be set in to motion is to create a conducive environment by creating the opportunities for them to exercise their holistic mind set. This will be done through the Economic Development for Communities Program through the nucleus estate projects and programs. This will be the focus in the next 10 years from 2010-2020.

However, there are approximately 1000 Lihirians who are ready for this stage, therefore 1 or 2 of the nucleus projects must be set up and implemented in the Phase 1 to create and give this people the opportunity to exercise their empowerment.

Business/Entrepreneurial Class Development =Setting the People Free

After the people have changed their mind set and have entered into micro-economic activities through the opportunities and the conducive environment provided to them, a new class of serious business minded individuals or families will developed out of this process. Not all Lihirians will be successful businessmen or women. Those that want to become very successful business men and women will create the Lihir Entrepreneurial Class. At this stage all we are required to do is to create a conducive economic and regulatory environment, a law & order free and corruption free society and set them free. This is the class of businessmen and businesswomen that will underwrite the development of the Lihir economy.

Self Reliance & Financial Independence

This is the end result of the four phases of development described above. This is the stage where Lihir as a society will have everything it needs and have the financial capacity to exist and continue to develop as a functional society.

3.6 Format of the Spread Sheet

As everyone is aware, LGL, NRLLG and LMALA have agreed on a K 100 million package for projects and programs identified in the LSDP for the next five years commencing in 2006 and ending in 2010. The final Spread Sheet will show how the K100 million will be appropriated. In negotiating the spread sheet the stakeholders (particularly LGL, NRLLG and LMALA) must ensure that the prioritizing of the projects is consistent with the LSDP particularly the destiny, vision, goal and strategy.

The stakeholders have also agreed to a spread sheet format that the parties will adopt for projecting the agreed projects/programs, associated infrastructures, capacity building programs and awareness programs that will be funded and implemented under the Revised IBP. The agreed Spread Sheet format has the following headings in this order.

(a) Projects/Programs

These projects/programs must be projects that will enable and ensure holistic human development. They must fall under one of the following developments:

(i) Mental Development

(ii) Physical Development

(iii) Emotional Development

(iv) Spiritual Development

(v) Financial Development

(b) Associated Infrastructures

Apart from the maintenance of existing public infrastructures, the infrastructures that must be funded and implemented are those associated or required for the implementation of the projects/programs identified in (b) above.

(c) Capacity Building Programs

Capacity Building Programs are those that are required to be put into place to upgrade the capacity of the implementing institutions to effectively implement the above projects.

(i) Systems/Policies

This includes institutional strengthening programs to upgrade and put into place the relevant systems and policies to enable a transparent, accountable and effective implementation of the projects/programs.

(ii) Training

This includes the relevant training that needs to be conducted to enable people to effectively staffed the required systems set up above.

(d) Evaluation & Monitoring

This is to ensure that evaluation and monitoring of the implementation of the projects/programs are done as intended.

(e) Awareness Programs in the Community

This contains the awareness programs to be conducted in all communities in Lihir to explain to them what the Revised IBP contains and how it will be implemented.

4. Summary of the Revised IBP

The K100 million has been budgeted under the five chapters of the Revised IBP. The allocation of the K100 Million package is as shown below.

Lihir Management Company Limited		December 31, 2004
Lihir Gold Mine — Mine Closure Plan Update 2004

EXECUTIVE SUMMARY

Lihir Management Company (LMC) manages a gold mining operation on behalf of Lihir Gold Limited (LGL). LGL is a public Company, the ownership lies between Institutions and the General Public (79.5%), Rio Tinto (14.5%), and Mineral Resources Lihir (MRL) (6.0%).

The operation comprises an open pit mine and ore processing plant with a throughput in excess of 4Mt of ore, producing up to 600,000 ounces of gold per annum. Supporting infrastructure includes port facilities, airstrip, diesel and geothermal power stations, water supply facilities, accommodation centre, access roads, and a communication system. The pit, process plant and other infrastructure are located on Lihir Island, New Ireland Province, Papua New Guinea.

Based on current projections, operations are expected to continue until 2040, assuming the cessation of mining activity in 2022, and the processing of the stockpiled low-grade ore for the remaining period.

Planned closure is divided into three stages:

Stage 1 — Open pit mine closure (2022);

Stage 2 — End of milling operations (2040); and

Stage 3 — Post closure monitoring.

A balance date closure scenario is also considered for unplanned closure on 31^st December, 2004.

The updated 2004 Mine Closure Plan was compiled by LMC staff to allow adequate planning and financial provision for closure activities; re-assessment of the environmental and bio-physical aspects of closure; and for the first time, consideration of socio-economic issues leading up to mine to closure, and beyond.

Page i


Lihir Management Company Limited		December 31, 2004
Lihir Gold Mine — Mine Closure Plan Update 2004

There have been a number of significant changes to the 1999 Conceptual Mine Closure Plan (CMCP) including:

	•		mill throughput increasing from 2.8 Mtpa to 4 Mtpa;

	•		changes to the harbour base rehabilitation strategy;

	•		mining additional pits including Lienetz and Kapit;

	•		removing the low-grade ore stockpile from the plan;

	•		orderly reductions in workforce numbers leading to mine closure; and

	•		orderly progress of rehabilitation activities leading towards mine closure.

The updated 2004 Mine Closure Plan addresses the above issues and accounts for:

	•		socio-economic considerations including community, government and corporate expectations and requirements for closure;

	•		the mine’s environmental setting; and

	•		the current environmental status of the mine.

It is recognised, however, that uncertainty exists regarding community and government expectations of closure (both current expectations, and at the time of closure). It is also possible that information may be incomplete or inadequate to define the extent of current and potential environmental impacts.

The updated Mine Closure Plan 2004 therefore presents the current closure commitments of the operation, whilst introducing the closure planning philosophy, to provide the framework to guide provincial and local level governments, mine affected landowners, and other Lihirian Communities, in making sustainable investment decisions on the use of their remaining mining benefit streams, in the lead up to and after mine closure.

LMC, on behalf of LGL, will review and update the Mine Closure Plan five yearly, as closure requirements become better defined. A decommissioning plan will be developed two to five years prior to the cessation of operations.

Page ii


Lihir Management Company Limited		December 31, 2004
Lihir Gold Mine — Mine Closure Plan Update 2004

A notional closure schedule has been developed. Where possible, staff reduction, rehabilitation and closure activities will be undertaken progressively prior to the cessation of operations. A further five years is allowed for post-closure monitoring and maintenance prior to lease relinquishment.

Based on current knowledge of closure requirements, 2040 raw closure costs have been estimated and are summarised in Table 1. The closure costs do not include indirect costs, engineering and construction management, progressive rehabilitation of active mining areas or asset sales.

Table 1 Estimated General Closure Costs (2040)


Component		Sub Total (Million PNGK)
Open pit and Mine		53.7
Process plant		25.2
Town and other infrastructure		6.6
Sub-total		85.5
Employee Redundancies		17.0
Five year monitoring period		27.4

The provision within the 2004 Financial Statements has been calculated and includes future costs to be incurred, and considers activities that will be completed during the operating phase (Appendix VI)

Consultation with all stakeholders including mine regulators, provincial and local level governments, mine affected landowners, and other Lihirian Communities will proceed ahead of final closure planning. The socio-economic impact of mine closure on Lihir will require management so that the detrimental affects are minimised.

A.1		INTRODUCTION

A.1.1		Location

		The Lihir Gold Limited’s (LGL) operations are located on Niolam Island, in the New Ireland Province of Papua New Guinea. As Niolam Island is the principal island of the Lihir Group, it is generally referred to as Lihir Island. At its widest points, the island measures 22 km from north to south and 14.5 km from east to west. Lihir Island has a surface area of approximately 197 km²and is situated approximately 900 km northeast of Port Moresby, the capital of Papua New Guinea, The mine site is located on the island’s east coast, see Figure A.1.1.

A.1.2		Project Overview

		The project comprises an open pit mine, ore processing plant, and supporting infrastructure including port facilities, airstrip, diesel and geothermal power stations, water supply facilities, accommodation camps and motel, access roads, and a communications system. The existing site layout is shown in Figure A.1.2.

		Ore processing is by pressure oxidation with high-grade ore processed as it is mined whereas low-grade ore is stockpiled in a number of locations for later processing. Tailing is discharged at depth to the ocean via a Deep Sea Tailing placement Pipeline (DSTP). Waste rock is deposited beneath sea water in Luise Harbour by bottom dump barges.

		Mining is expected to continue until the end of 2022 and, following cessation of mining activity, processing of the stockpiled low-grade ore will continue for approximately 22 years, nominally until 2040. This is followed by a two year closure works period and a further five year monitoring period to 2046. The mine and mill operating schedule is shown on Figure A.1.3.

A.1.4.2		Discovery and Exploration

		A geological survey of Papua New Guinea, conducted by the Bureau of Mineral Resources (BMR) between 1969 and 1974, identified hydrothermal alteration and thermal activity on Lihir Island, suggesting an environment favourable to epithermal gold mineralization. Following sampling in 1982 by Kennecott Explorations Australia (KEA) and its joint venture partner, Niugini Mining Limited, a major drilling exercise was initiated, which by the end of 1984 had identified the presence of a large gold resource.

		In 1988 the RTZ Corporation (now Rio Tinto) acquired Kennecott from BP Minerals America, thereby taking over as the Lihir Joint Venture partner with Niugini Mining Limited. Following test drilling, metallurgical, geotechnical, geothermal, groundwater, environmental and engineering studies, a Feasibility Report was produced in 1992 and submitted to the Papua New Guinea Government. After extensive community consultation, the Joint Venture was issued with a Special Mining Lease in 1995 and later that year, Lihir Gold Limited (LGL) acquired the Lihir Joint Venture Project. Site clearing began in 1995 and, in accordance with the negotiated agreements, villagers occupying the area designated for the process plant site were relocated to new village sites. The processing plant was completed in 1997 and the mine began

		producing gold soon after. Since then, annual gold production has increased from about 244,000 ounces to over 600,000 ounces.

A.1.5		Approach to closure planning

		The mine closure plan is being developed towards compliance with:

	•		PNG Government’s policy and regulatory requirements;

	•		LMC loan agreements and lease conditions including the Special Mining Lease;

	•		LMC commitments given in the 1992 Environmental Plan;

	•		LMC commitments given in the 1995 Integrated Benefits Package, (now under revision);

	•		Rio Tinto policy, business practice, closure planning standards and guidelines; and

	•		International standards for best practice.

		These documents are discussed further in Section A.3 — Regulatory, Company and Other Framework criteria. Costs for all closure activities have been estimated following discussions with LMC personnel during interviews and site visits conducted throughout September to December 2004. Costs are in 2004 PNG Kina without allowance for future inflation or discounting.

		As required under the Department of Mining’s proposed guidelines for Community Sustainable Development Planning (CSDP) for all major mining projects (DOM 2003), the MCP will be a rolling 5-year plan, subject to annual review. A final closure plan will be prepared by LMC and submitted to the Government in the last five years of the project.

		The terminology of the CSDP has not been finalised and current discussions suggest the term Socio Economic Development Plan (SEDP) may be preferred by the government. Consequently the terms SCDP and SEDP are used in this report and apply to the same process.

A.1.6

Scope of This Report

		The document, is presented in four parts and updates the LMC mine closure plan, five years after the Conceptual Mine Closure Plan (CMCP) was issued in 1999 (LMC 1999). The updated mine closure plan, in addition to documenting advances in physical closure works planning, significantly updates the socio-economic aspects of the 1999 CMCP. The report puts into context the LMC philosophy of long term sustainable development planning to ensure long-term benefits to the community during and after the operation of the mine.

		In addition to updating information contained within the 1999 CMCP, the report is designed to:

	•		Help ensure that adequate provision of funds is being made to meet closure costs;

	•		Enable closure considerations to be integrated into current operations planning;

	•		Identify regulatory and corporate requirements, commitments and agreements;

	•		Provide the basis for the preparation of future updates as closure planning parameters become better known;

	•		Identify areas of investigation required for the closure plan; and

	•		Provide a framework for discussion between LMC and local landowner groups and State and Provincial governments.

		The 2004 Mine Closure Plan is presented in four parts: Part A (Preamble), Part B (Environment and Bio-physical), Part C (Socio-Economic) and Part D (Summary and Conclusions).

		Part A (Preamble) provides a discussion of general items, and background.

Page 6


Lihir Management Company Limited		December 31, 2004
Lihir Gold Mine — Mine Closure Plan Update 2004

		Part B (Environmental and Biophysical) describes the environmental issues, impacts, requirements, commitments, plans and costs relating to closure of the mine site.

		Part C (Socio-Economic) describes the socio-economic issues, requirements, commitments, plans and costs relating to closure of the mine site, including the aims and plans to help achieve sustainable development for the people of Lihir Island.

		Part D (Summary and Conclusions), provides an overall summary and an action item list.

		Addressing environmental and socio-economic issues in separate parts recognizes that social issues and the needs and wishes of the various stakeholders are integral to mine closure and the successful sustainable planning.

		Although each part of the report is tailored towards a slightly different audience, the parts are cross referenced and closely linked. Therefore each part should be read in conjunction with the others to promote an understanding of all of the issues and commitments relating to the life and eventual closure of the mine.

		The Mine Closure Plan is a work in progress and will evolve over the life of the mine.

A.2		PROJECT SETTING

A.2.1		Climate and Precipitation

		Temperatures at Lihir are relatively constant from month to month and vary little throughout the day. The average range is from 19^oC to 35^oC and relative humidity is consistently high. Two wind seasons occur over the year and vary in duration from year to year, but generally the winds are predominantly from the south-east in May to October and from the northwest in November to April.

		Rainfall on Lihir Island is relatively evenly distributed throughout the year with no strong wet or dry seasons evident. However the rainfall varies enormously across the island and with altitude. The average precipitation at the mine site is 4,800 millimetres per year. Because of its latitude, 3º 07 S, the island is not affected by tropical cyclones being well above the southern cyclone belt.

A.2.2		Topography

		Much of the island is mountainous, with several peaks rising up to 600 m above sea level. Sub-catchments in the upper elevations of the Luise Caldera are steep and vary in elevation from about 100 m – 550 m above sea level. Vegetation in these catchments is generally undisturbed, dense and characterized as primary rainforest. The narrow coastal plain and nearby slopes are widely used for subsistence gardening and have secondary growth cover. Parts of the narrow coastal plain, particularly in the northern and eastern areas are formed on coral platforms.

		The seabed drops away rapidly from the coastline and in many places submarine cliffs occur below the corals which fringe the coast. Below the drop offs, the ocean floor lies at a depth of approximately 1600m deep immediately around the island. Further out there is a series of ocean trenches, which are the assumed ultimate location for tailings and reach depths of over 3000 m. Because of its origins within a volcanic crater, Luise Harbour features a gently shelving seabed composed mainly of muddy, fine-grained volcanic sands with some detached coral reefs, which become partly exposed at low tide (LMC 1992).

Page 8


Lihir Management Company Limited		December 31, 2004
Lihir Gold Mine — Mine Closure Plan Update 2004

A.2.3		Geology

		Lihir Island was formed during periods of intense volcanic activity. Luise Caldera, in which all of the known ore deposits are located, is the youngest of the volcanic features in the area. The northeast slopes of the Luise caldera have collapsed allowing part of the caldera base to become submerged by the ocean to form Luise Harbour.

		The rocks of the caldera are primarily comprised of andesitic and basaltic lava flows, tuffs and agglomerates which have been subjected to different types of alteration, mineralization and hydrothermal activity. Gold mineralization occurs in the central part of the caldera and all of the rocks in the vicinity of this mineralization have been affected by hydrothermal activity (LMC 1992).

		Geothermal reservoirs are present in the caldera, covering an area of at least 2 km². Discharges in the form of thermal hot springs and fumaroles occur in surrounding areas. Steam and gas discharges occur on the nearby Kapit Beach and zones of submarine gas seepage are regularly observed in Luise Harbour. Discharges of hydrogen sulphide are commonly associated with all of these features.

		The geothermal reservoir is fed by hot fluids that rise from the depths along geologic fractures, mix with infiltrating rainwater and eventually discharge to the sea. At shallow levels of the system, temperatures can reach 100^oC at the water table and can exceed 200^o C at depth.

		Several adjacent and partly overlapping ore deposits lie beneath the floor of the Luise Caldera. The major reservoirs are known by Minifie, Lienetz and Kapit as summarised in Table A.2.1. Ore reserves are thought not to extend under the steep slopes of the caldera rim.

Lihir Gold Mine — Mine Closure Plan Update 2004

Table A.2.1 Summary of Ore Deposits


DEPOSIT		GOLD MINERALIZATION
Minifie		Occurs mostly between the original ground surface (about 50 metres above sea level) and 150 metres below sea level.
Lienetz		Occurs at elevations between 140 metres above and 250 metres below sea level.
Kapit		Occurs between 50 metres and 250 metres below sea level.

A.2.4		Seismology

		Lihir Island is located at about 3^o 07’ S and 152^o 38’ W in the West Melanesian Arc seismic source zone of Papua New Guinea (Ripper and Letz, 1993). Several magnitude 8 and above earthquakes have been attributed to this zone. New Ireland and Lihir Island lie just north of the likely limit of the contact between the South Bismark Plate and the Solomon Plate as it wraps around New Britain. The area is one of the most highly seismically active plate margins in the world. Consequently, frequent, small nearby earthquakes and infrequent, more distant but potentially destructive large earthquakes can impact the mine site.

A.2.5		Hydrogeology

		The groundwater system in the pit area is highly complex and includes flows derived from rainfall infiltration into the upper regions of the caldera, sea water intrusions and erratic high pressure areas caused by volcanic activity. An extensive system of depressurizing, dewatering and cooling water/steam wells exist in and around the pit.

A.2.6		Hydrology

		The Island has a large number of watercourses, the largest of which are the Londolovit River (which drains to the northeast coast) and the Wurtol River (which drains to the southwest coast). Key watercourses relating to the site are the Londolovit River and the two main streams draining the caldera: Kapit and Ladolam Creeks. The latter two discharge into Luise Harbour.

Page 10



Lihir Management Company Limited		December 31, 2004
Lihir Gold Mine — Mine Closure Plan Update 2004

		Rainfall is highly variable on a day to day basis. During high rainfall, sediment is rapidly transported into the Harbour contributing to the formation of a sediment plume. The plume, which is observed regularly, is significantly influenced by surface water runoff and groundwater discharge from the site.

A.2.7		Vegetation

		There are four main pre-mining vegetation zones present on Lihir as in Table A.2.2.

Table A.2.2 Vegetation zones


VEGETATION ZONE
(AND APPROX. ELEVATIONS)		DETAILS
Shoreline		Hibiscus and other common strand formation plants.

Coastal Plain: 10-175m above sea level		This belt contains secondary forest, grassland, gardens and garden regrowth, settlements and plantations. Key vegetation includes: coconut and cocoa, areca palm, bamboo, breadfruit, banana, sago, paw paw and other trees.
175-400m		Steep terrain, mainly a mosaic of secondary to more mature rainforest. Lower hill slopes and deeper soils have garden and garden regrowth areas.
400m and above		Rugged terrain with steep slopes, thin soils with mature forest, not used for gardening.

A.2.8		Fauna

		A diverse range of terrestrial fauna exists, with similar distributions to the rest of New Ireland. Fauna includes marsupials, reptiles, amphibians, rodents and mammals including wild pigs. There is a rich bird population, including forest dwellers, sea birds and waders. One particular bird (the Melanesian scrubfowl — Megapodius eremite eremit, a member of the megapode family) uses the geothermal areas to incubate its eggs. Pigs and megapode eggs are traditionally significant as a source of food.

		There is an absence of large rivers or estuaries on the island and it is thought that this has limited the establishment and adaptation of marine species in the freshwater environment. The streams which drain the mountains of Lihir are short and fast flowing with erratic flow volumes almost drying up in low flow periods and producing

Page 11



Lihir Management Company Limited		December 31, 2004
Lihir Gold Mine — Mine Closure Plan Update 2004

		torrents during heavy rain. Fish habitats on the island occur mainly in the low-gradient zones along the narrow stretch of coastal plain and are characterized by riffles and pools. Freshwater fauna consist mainly of fish, prawns and eels (LMC 1996).

		Within Luise Harbour, there exists bottom dwelling (benthic) fauna such as macro-invertebrates in the form of worms and burrowing and surface crustaceans and a small benthic fish population.

		Coral reefs fringe the coastline of the island and provide a rich marine habitat. There are not many live corals in the shallow water due to wave disturbance but at greater depths a variety of corals exist. At depths greater than 50m and below, the corals are less in number and are more thin and brittle. Marine fauna such as molluscs, starfish and sea-cucumbers live in the shallow water and many types of crustaceans such as crab, lobster and shrimp live in the reef areas.

		A rich variety of reef fish make up the largest group of fish around the island. Ocean fish (Pelagics) are also numerous and include squid, tuna and sharks. Turtles have been observed in the ocean, and in particular Leatherback Turtles, which have in the past infrequently used a section of the Kapit beach to lay their eggs. Little is known about fauna in the deep surrounding ocean floor and trenches.

A.2.8.1		Air Quality

		Ambient air quality can vary throughout the year due to natural and anthropogenic sources. In addition to process plant discharges to atmosphere, mining activities and weather conditions can combine to create localised levels of dust, and LMC operate dust suppression measures such as spraying water on haulage roads to counteract this.

		Natural sources affecting air quality include emissions from the geothermal wells and hot springs, which discharge steam and gases including hydrogen sulphide to the air.

Lihir Gold Mine — Mine Closure Plan Update 2004

A.2.9		Socio-economic Environment

		A brief synopsis of the traditional socio-economic environment is described below.

A.2.9.1		Population and Settlement

		The population of Lihir Island is mainly spread among villages around the coast with less in the more rugged parts of the island. Londolovit is and remains the population centre of the island.

A.2.9.2		Land Use

		Approximately 90ha of plantations of coconut, cocoa and sago were located within Luise Caldera prior to the mine development. Near the coast, the caldera also contained extensive thickets of bamboo which were used by the villagers for building materials. Behind the plantations were approximately 60ha of garden and garden regrowth. Further inland and on the lower slopes was secondary forest that contained a few active gardens. On the steeper and higher slopes, more mature forest existed and is still evident today.

A.2.9.3		Economy

		Villages on Lihir Island and the nearby islands traditionally have subsistence economies comprising shifting cultivation and wild pig farming. Gardens provide a major source of food including a variety of vegetables and fruit. The islanders traditionally obtain many of their raw materials and foods from the forest, including timber, sago and bamboo for building purposes. Although garden cultivation provides the main source of food, fishing in the sea remains an important food source and social activity.

A.3		REGULATORY, COMPANY AND OTHER FRAMEWORK CRITERIA

A.3.1		Legislative Requirements

A.3.1.1		Relevant Acts

		The main acts governing mining operations in PNG are:

	•		Environment Act (2000).

	•		Mining Act (1992).

A.3.1.2		Environment Act (2000)

		i) General

		A new environment regime was introduced to Papua New Guinea (PNG) by the Environment Act 2000 and its associated regulations. The Environment Act 2000 (the Act):

	•		repealed the Environmental Planning Act (1978), Water Resources Act (1982) and the Environmental Contaminants Act (1978), and incorporated their requirements;

	•		imposed a regime of environmental approvals and licensing aimed at protecting PNG’s environment (applies to, and may affect, both new and existing projects); and

	•		established the Environment Council as a crucial decision making body.

		Statutory environmental requirements have remained unchanged under the new Environment Act, and the present LMC Water Use Permits (WUPs) that were issued prior to the 2000 Environment Act, will continue to operate with the new regime.

		ii) Water Permits

		Water Use Permits (WUPs) are issued by the PNG Department of Environment and Conservation to regulate water extracted from rivers and the ocean, and limit the volume and concentration of discharged pollutants. Concentration limits detailed in WUPs are based on international standards for the protection of fresh and marine

Page 14



Lihir Management Company Limited		December 31, 2004
Lihir Gold Mine — Mine Closure Plan Update 2004

		waters including the Australian and New Zealand Environment Conservation Council (ANZECC) 2000 Guidelines for fresh and marine water quality. LMC’s compliance with the requirements of the WUPs is monitored through the current Environmental Monitoring and Management Program (EMMP 2004-2007). A listing of the 23 original LMC Water Use Permits is attached in Appendix II. Five permits have since lapsed or been amalgamated into 18 valid water use permits.

A.3.1.3		Mining Act (1992)

		The section of the Mining Act 1992 of direct relevance to closure is Section 152 “entitled removal of mining plant, ore, tailings, etc., on expiry, etc. of tenement”. Implications of Section 152 for closure are:

		Mining plant can be either removed by the holder of a tenement following surrender of the tenement, or be sold by the Department of Mining and removed. In the event of a sale, the proceeds are retained by the State. However, this section is interpreted subject to the existence of any valid agreement between the holder of the tenement and owner of the land where the plant is located.

		Any tailings, other materials or mined ore left upon the land following surrender of the tenement and not within a prescribed period removed or treated by the holder of the tenement, shall become the property of the State.

		In addition, Section 19 of the Act states that a mining development contract takes precedence over the Act, except where conflict between regulators and developers exists, in which case the provisions of the Act prevail. In the case of the Lihir Gold Mine, therefore, Section 152 is not applicable to Special Mine Lease 6 (SML 6) covering the area of mining operations, but is presumed to be applicable to leases granted for quarrying and the provision of infrastructure (e.g. Lease for Mining Purposes Nos. 125 and 126, Lease for Mining Purposes Nos. 34 and 35, and Mining Easements Nos. 71, 72 and 73).

Page 15



Lihir Management Company Limited		December 31, 2004
Lihir Gold Mine — Mine Closure Plan Update 2004

A.3.1.4		Other Acts

		The Environment Act 2000, repeals a number of environmental statutes. Those which remain and are in part applicable to LMC’s operations are listed below;

	•		Public Health (Drinking Water) Act (1984).

	•		Conservation Areas Act (1980).

	•		Dumping of Wastes at Sea Act (1979).

	•		International Trade (Fauna and Flora) Act (1979).

	•		Fauna (Protection and Control) Act (1966).

		These Acts only have a minor impact on Lihir operations beyond the requirements of the Environment Act 2000 and Mining Act 1992.

A.3.2		Corporate Requirements, Loan Agreement and Lease Requirements

		In addition to the regulatory requirements for mine closure, there are a wide variety of LMC and other Corporate documents having relevance to closure. In addition certain loan and lease agreements require adherence to environmental performance which impact closure. There are also international standards of good practice dealing with closure. Many of these requirements and standards cover similar issues and goals. The main identified documents are listed in Tables A.3.1 and A.3.2, with selected items discussed further in Appendix 1.

A.4		PROJECT DESCRIPTION

A.4.1		Site Layout

		The current site layout is shown in Figure A.1.2 and the following sections provide a general description of the project components.

A.4.2		Mining and Milling Operations

A.4.2.1		Ore Reserve

		Mineable reserves at the end Q2 2004 amount to about 566,000 Kg of recoverable gold, contained in 161 million tonnes of ore, averaging about 3.52 grams of gold per tonne.

A.4.2.2		Brief overview of the mining and milling schedule

	•		Site operations began in 1995;

	•		Mining of the Minifie ore body, processing of high grade ore and stockpiling of low grade ore began in 1997;

	•		Mining of the Lienetz ore body started in 2002;

	•		Mining of the Kapit ore body to follow in 2010 after the low-grade stockpile that currently lies on top of it is removed;

	•		All mining operations are anticipated to finish in 2022;

	•		Low Grade Stockpiles to be processed following cessation of mining;

	•		Milling ceases in 2040 after processing of the low-grade stockpiles ends.

Mining operations remove about 47 million tonnes of waste from the pit per annum. Most of the waste rock is transferred using haul trucks to bottom-dump barges, and then disposed in the harbour. Table A.4.1 shows ore, waste and tailings cumulative production at key dates.

A.4.3.3		Mining

		Mining is undertaken using RH200 shovels loading a fleet of Cat 785 and 777 haul trucks. Much of the mined material is soft enough to free dig but blasting is carried out as a safety precaution against mining into high pressure geothermal zones.

		The mine equipment fleet is serviced in the plant workshop and associated warehouse, tyre shop and miscellaneous buildings. Mine operations has its own set of offices, fuel station and crib hut.

		The Barge Wharf is specific to the mine, and the barges themselves are contractor operated.

		The pit also has its own screening plant for crushing and screening aggregate for drill hole stemming and general use.

		The mine equipment fleet also includes, CAT 375 Excavators, D10 Dozers and drills, graders and loaders.

		The mine is dewatered, depressurized and cooled in advance of mining activity by a system of bores. A large number of horizontal bores are installed for localized depressurization of the in-pit walls. Discharges from bores are currently directed, by

		pumping as necessary to the two perimeter drainage channels (Kapit and Ladolam). Plans are being developed to collect these discharges, separate contact from non-contact water, and discharge the effluent in a controlled manner to Luise Harbour.

		Surface water due to rainfall and runoff is collected in a series of sumps in the pit. The position of these sumps are moved as work in the pit progresses. Collected runoff is currently pumped to the Ladolam perimeter drainage channel on the southern side of Minifie pit and discharged to Luise Harbour. The flow will also be collected and separated from non-contact water for controlled discharge.

A.4.3.4		Pit Walls

		The pit wall rock consists of weak weathered material often of high temperature. As such there is limited precedent for assessing wall stability during development. Experience being obtained through observation of current mine performance will be used to develop stable final pit walls. At closure, the pit-wall area above sea level is estimated to be about 196 ha of which over 50% is expected to comprise Potentially Acid Forming (PAF) material.

A.4.3.5		Coffer Dam

		The current mine plan requires construction of a coffer dam in Luise Harbour to allow development of the Kapit Reserve. Due to the quantities and timing of material required it is most likely that the bulk of material used for embankment construction will be ROM waste and hence PAF.

A.4.4		Stockpiles

		The mine plan adopts a declining cut-off grade strategy, which requires the highest grade ore to be processed first with low grade material stockpiled for late processing. The following section discusses the strategy for handling the high and low grade.

A.4.4.1		Run of Mine (ROM) Stockpiles

		Run Of Mine (ROM) stockpiles are located in the area adjacent to the primary crushing station and receive High Grade Ore (HGO) from the pit (see Figure A.1.2).

Page 22



Lihir Management Company Limited		December 31, 2004
Lihir Gold Mine — Mine Closure Plan Update 2004

		The ore is processed at the crushing station and transported to the processing area via a conveyor system. The ROM stockpile is classified depending on sulphur content (high, medium and low) to control the sulphur grade sent to the processing plant.

A.4.4.2		Low Grade Ore (LGO) stockpiles

		The current mine plan includes provision for the stockpiling of approximately 90 million tonnes of low grade ore. Current stockpiles include Kapit South, Kapit North and Harbour Platform low-grade ore stockpiles, see Figure A.1.2.

		Development of Kapit Pit will require relocation of the Kapit North stockpile and development of the Kapit Village and Wild West low grade stockpiles, see Figure A.5.2. Low grade ore will also be stockpiled within Minifie pit towards the end of pit life.

		The low grade ore is Potentially Acid Forming (PAF) and reactivity varies greatly ranging from days to weeks while other material may have a lag period of several years.

A.4.4.3		Topsoil Stockpiles

		Topsoil is removed from areas that are required for site operations. The topsoil is either used to aid re-vegetation of disturbed areas no longer affected by site operations or stockpiled for later use. The estimated current volumes of the main topsoil stockpiles (Kapit and Magazine) are about 83,000 m³ and 499, 000 m³ respectively.

A.4.5		Process Summary

A.4.5.1		General

		Within the sulphide ore, gold occurs in Iron Sulfide (Pyrite) crystals. The pyrite is reacted with oxygen under high pressure and temperature in an acidic environment, and the gold is recovered via Carbon-In-Leach (CIL) processing.

Page 23



Lihir Management Company Limited		December 31, 2004
Lihir Gold Mine — Mine Closure Plan Update 2004

		Ore is loaded into the primary crusher hopper by haul truck and after crushing, is transferred via a conveyor system to the run-of-mine stockpile at the processing plant located at Putput Point (approximately 1 km east of the mine) (Figure A.1.2). Crushed ore proceeds to the grinding circuit (comprising a Semi-Autogenous Grinding (SAG) mill and a ball mill). Following milling, the ore is washed and thickened to remove chlorides and stored in pre-oxidation tanks before being oxidized in the pressure oxidation autoclaves.

		Slurry from the pressure oxidation process is then subjected to Counter Current Decantation (CCD) thickeners to remove soluble acidic materials. Neutralization of the acid is then achieved using lime to raise the pH to a minimum of 10. Sodium Cyanide solution is used to leach the gold from the slurry before the gold is desorbed from solution onto carbon in a CIL circuit. The carbon is washed in hydrochloric acid and the gold is then recovered by an electro-winning and an electro-refining process before being smelted into gold bullion.

A.4.5.2		Improvements to Milling Operations Since Start Up¹

		A number of improvements have been made to the milling operation since start-up in 1997 and this has led to an increase in throughput from the original design capacity of 2.8Mtpa to 4Mtpa. Major areas of improvement have included;

	•		Installation of additional oxygen generation capacity;

	•		Installation of additional power generation capacity;

	•		Installation of a pilot flotation plant;

	•		Improvements in autoclave availability and modification to internal design;

	•		Installation of a heat recovery circuit to recycle heat generated in the autoclaves;

	•		Installation of a pebble crushing circuit;

•

Additional autoclave feed pumping capacity.

		Various improvements have expanded the processing plant’s operating range allowing greater flexibility in processing varying grades of ore hardness and sulphur. Further upgrades may be done prior to closure and will be incorporated in later updates to the mine closure plan.

A.4.5.3		Utilities

		Raw water for process is pumped from Londolovit weir and supplemented by collection of caldera catchment water.

		Potable water for the Putput village is supplied by clean water pic ups from the caldera creeks.

		Power for the mine and mill site is generated by a 50 MW oil fuel power station, a 6 MW additional plant, with a 30 MW geothermal plant under construction.

		Domestic and industrial waste is disposed of in an incinerator located on-site. The incinerator reduces the volume of waste buried in landfill pits. Sewage is discharged to the Deep Sea Tailings Pipeline (DSTP) for ocean disposal.

A.4.6		Waste Rock

		Waste rock characterization, ARD potential and disposal

		Waste rock at the site is divided into two main classes, soft waste rock (incompetent) and hard waste rock (competent). Soft waste rock comprises soil and marginal rock which often breaks down to a soil when exposed and reworked. Hard waste rock is made up of durable rock which does not breakdown or degrade. The vast majority of waste rock is PAF with short lag times. The remaining life of mine mass of waste rock is about 680 Mt with the vast majority placed in Luise Harbour (see Figure A.1.2). Haul trucks transport the waste rock to bottom-dump barges which then travel out to the designated disposal point and dump the rock. A fleet of five 975 m³capacity self propelled bottom-dump barges operate 24 hours a day,

Page 25



Lihir Management Company Limited		December 31, 2004
Lihir Gold Mine — Mine Closure Plan Update 2004

		receiving the waste rock at the loading dock and travelling to and from the disposal site.

		Large waste sinks rapidly to the ocean floor, which was originally between 300 and 500m below sea level at the dump point. Fines from the bottom dumped waste and wash waste from the barge doors is a source of surface contaminant plumes in Luise Harbour. The depth of the waste pile is monitored and reported in accordance with the applicable Water Use Permit (WUP).

		Competent waste rock has been used to construct the Harbour Platform, which is an area of reclaimed land at the edge of Luise Harbour used for low grade ore stockpiling, see Figure A.1.2. The bulk of waste rock in the Harbour Platform is PAF and will require removal below sea level at mine closure to limit long term acid generation.

		A small amount of hard waste rock is stockpiled on land, for use in haul road maintenance and as armouring for perimeter drainage channels.

A.4.7		Tailings Management and Disposal

		Various effluent streams including the tailings from the gold processing plant are directed to a mix tank and then de-aeration tank prior to discharge. The de-aeration tank process is designed to release entrained air in the tailings stream to the atmosphere prior to discharge. The effluent is discharged to the sea via the Deep Sea Tailings Pipeline (DSTP). The pipe runs at a steep gradient in a tunnel through a coral platform to a depth of 125 m below sea level before the tailings are discharged to the ocean. The tailing solids eventually deposit on the seabed at depths of between 900 to 2,000 m. It is expected that over the life of the project, the quantity of tailing solids will be in the order of 200Mt.

		The discharge of tailings to the ocean is regulated by Water Use Permit (WUP) (#29/990) issued by the PNG Government (see Appendix II). The WUP specifies allowed discharge rates and water quality criteria applicable within a designated offshore mixing zone. Regular monitoring is undertaken at multiple locations and

Page 26



Lihir Management Company Limited		December 31, 2004
Lihir Gold Mine — Mine Closure Plan Update 2004

		depths throughout the mixing zone and also at the de-aeration tank prior to discharge.

		The effluent streams discharged via the outfall include:

	•		Thickened Carbon-in-Leach (CIL) tailings;

	•		Counter Current Decantation (CCD) washwater from the pressure oxidation autoclaves;

	•		Cooling water from the oxygen and power plants;

	•		Sewage from the processing plant and mine areas; and

	•		Seawater pumped to the de-aeration tank when necessary to prevent air entering the pipeline.

		There are plans in place to increase the rate of the discharge through the tailings line.

A.4.8		Townsite, Infrastructure, Buildings and Services

		A list of on and off-site facilities is presented in tabular form in Part B and is summarised below.

A.4.8.1		Townsite

		The Londolovit townsite accommodates about 2,000 people and includes family housing, duplexes, dongas, recreational facilities, government offices and schooling, medical centre and other infrastructure and buildings. Utilities include potable water from Londolovit weir, power from a nominally 6 MW generating plant, supplemented by townsite diesel generators. Sewage is treated in a sewage treatment plant at the townsite before being discharged to the ocean. Domestic waste is treated at an incinerator on the mine site and any excess waste is burned and buried in a landfill facility. An airstrip located north of the townsite is surfaced with coronous material and is used for daylight activity.

Page 27



Lihir Management Company Limited		December 31, 2004
Lihir Gold Mine — Mine Closure Plan Update 2004

A.4.8.2		Port Facilities

		A general purpose wharf has been constructed in the vicinity of the plant to facilitate cargo ships that dock at the site. A small boat harbour has also been constructed nearby, protected by a breakwater. Traffic through the port comprises of imports of fuel oil, mine and processing plant consumables and general cargo. The small boat harbour is used for work boats and other general boating requirements.

A.4.8.3		Mine Site Roads

		Within the mine area, over 4 km of haul roads have been constructed outside of the pit, leading to the crusher, maintenance facilities, waste rock, ROM stockpile and low grade stockpiles. Hard mine waste rock and crushed basalt are used in the construction of these roads. Other roads connecting the remaining parts of the site accommodate a fleet of light vehicles.

A.4.8.4		Public Access Roads

		A ring road has been constructed around the Island connecting all major villages and population centres.

A.4.8.5		Telecommunications

		The basic communications system on the island was substantially upgraded during site development and now provides high-quality links with New Ireland, Port Moresby, other parts of PNG and overseas. Included are a microwave link and a telephone network to provide services for the public and mine operations. Radio, television and satellite transmission facilities are established.

A.4.9		Quarries

		About 9 major quarries and 10 smaller pits have been used on the island to provide a variety of materials for aggregate and pavement surfacing materials during construction and operations phases. The locations of selected quarries are shown in Figure A.1.2. Basalt makes up the bulk of the surfacing material for the haul roads as well as aggregate and fines for concrete production. Coronous material is used

Page 28



Lihir Management Company Limited		December 31, 2004
Lihir Gold Mine — Mine Closure Plan Update 2004

		for road surfacing as it is durable and readily available. By the end of operations in 2044, quarries, occupying a total area of approximately 40 ha, are expected to have been mined. Quarries no longer in use are progressively rehabilitated (Photo 39, Appendix V).

A.4.10		Surface Water Run-off and Sediment Control

A.4.10.1		Surface Water

		Since construction and the beginning of mine operations, the two main streams within the caldera (Kapit and Ladolam Creeks) have been modified to become drainage conduits for the mine-pit perimeter drainage system, geothermal waters and mine contract water. Various sections are lined with high density polyethylene and/or rip rap as a mean of erosion control. The drains discharge to Luise Harbour near the mouths of the original creeks, as indicated on Figure A.1.2

		The channels allow some cooling of hydrothermal waters before discharge. They also direct flow into sediment traps which a) significantly reduce the amount of suspended material entering the harbour and b) allow further time for water containing geothermal discharges to cool prior to discharge to the Luise harbour.

		Work is also underway to intercept contact water, separate the flows from non contact water and re-direct flows to controlled discharge to Luise Harbour.

		It is expected that the non-contact water diversion channels will be maintained at closure but may be incrementally modified, replaced and rebuilt as the pit expands.

A.4.10.2		Sediment Control Strategy

		A surface plume of suspended sediment is regularly observed in Luise Harbour and is thought to mainly result from the following:

	•		Suspended fines from the waste rock material discharged from the bottom opening barges;

	•		Erosion of the diversion channels, harbour base and low grade stockpiles;

Page 29



Lihir Management Company Limited		December 31, 2004
Lihir Gold Mine — Mine Closure Plan Update 2004

	•		ARD leachate from the harbour base on-land stockpiles; and

	•		Pit sump, pit dewatering bore and geothermal discharges.

		A Mine Water, Sediment and ARD Management Plan (MWSAMP) has been devised to help address the discharge of contact water to Luise Harbour and the associated sediment plume issues. The MWSAMP is an operational strategy but is described here since elements of it will remain as part of closure.

		The plan includes a number of engineering strategies for the separation and collection of sediment and water runoff from the mine site including:

	•		The construction of pit perimeter diversion drainage channels to segregate the clean runoff from undisturbed regions of the caldera catchment from mine site contact water.

	•		Optimisation of the Kapit sediment trap to better collect and retain stream-derived sediment.

	•		Lining of pit drainage channels to minimise erosion and associated high sediment runoff.

	•		Collection of pit sump, hydrothermal and dewatering well and Kapit North low grade stockpiles contact waters and directing them to a mix tank and then to a controlled discharge.

	•		The improved collection of spillage and wash down of ore from the conveyor system and stockpiles at the processing plant.

A.5		CLOSURE SCHEDULE AND STRATEGY

A.5.1		Closure Schedule

		The process of mine closure planning was initiated during the development of the mine and has been a part of on-going site operations since then. The planning process involves the development of a conceptual mine closure plan, ongoing mine and environmental planning, and stakeholder discussions.

		In this report three separate closure planning scenarios are considered as follows:

	•		Planned closure consisting of Stage 1 — Pit closure, Stage 2 — Final closure and Stage 3 — Post closure monitoring. This is the preferred closure schedule.

	•		Balance date closure, to conform with general accounting practice, in which closure liabilities at end of 2004 are assessed. This condition is analogous to unscheduled sudden closure.

	•		Changes since the 1999 Conceptual Mine Closure Plan summarised to provide a comparison to the 2004 closure plans listed in the preceding two bullets.

		The closure schedule adopted for the Planned Closure is shown in Figure A.1.3. The closure schedule for the Balance Date closure is shown on Figure A.5.1.

A.5.2		Planned Closure

A.5.2.1		Stage 1 — Pit Closure

		Cessation of mining is expected at the end of 2022 at which time Stage 1 — Pit Closure will occur. At that time, open pit mining and waste rock disposal will cease. Milling operations will continue to process stockpiled low-grade ore. The site arrangement in 2022 is shown on Figure A.5.2 and a schematic of the proposed stockpile use is presented in Figure A.5.3.

		Stage 1 closure will involve flooding of the open pit, decommissioning or downsizing of the associated equipment fleet and buildings and some downsizing of the accommodation camp.

Page 31



Lihir Management Company Limited		December 31, 2004
Lihir Gold Mine — Mine Closure Plan Update 2004

A.5.2.2		Stage 2 — Final Closure

		Processing of low grade ore is expected to be completed in 2040 at which time Stage 2 — Final Closure will occur. Stage 2 will involve removal and decommissioning of plant site buildings, structure and infrastructure and transfer of assets to the local community and/or regulators as required. Closure activities will include remediation and revegetation of the decommissioned areas and removal and disposal of the Kapit pit coffer dam embankment and Harbour Base.

		Unwanted buildings in the town site will be demolished with the remaining buildings transferred over time to the local community and/or regulators. Kapit Village will be re-established. The closed Stage 2 condition is illustrated on Figure A.5.4.

		Major capital works are expected to be completed during 2040 and 2041.

A.5.2.3		Stage 3 — Post Closure Monitoring and Maintenance

		Monitoring is a continuous part of site operations and will continue from 2022 (Stage 1 closure) until 2040 as an operational cost. Monitoring during Stages 2 and 3 is considered a closure cost.

		Stage 1 post closure monitoring will commence at the cessation of mining and continue until the end of Stage 2 post-closure monitoring.

		Stage 3 post closure monitoring will commence at the cessation of the main closure works and continue for five years from 2042 to about 2046, or until the achievement of compliance with appropriate closure criteria, whichever is the longer.

A.5.2.4		Balance Date Closure

		The selected Balance Date for closure is December 31, 2004. Closure of the operations then would hypothetically involve cessation of mining and milling and securing or removing the low grade stockpiles in a manner to achieve compliance with post closure criteria. In addition, decommissioning of buildings and

Page 32



Lihir Management Company Limited		December 31, 2004
Lihir Gold Mine — Mine Closure Plan Update 2004

		infrastructure similar to that outlined in the Planned Closure options would be needed.

		The conditions immediately prior to Balance Date Closure are shown on the current site general arrangement drawing, Figure A.1.2, while the closed condition is shown on Figure A.5.5.

A.5.2.5		1999 Conceptual Mine Closure Plan (CMCP)

		The 1999 CMCP is similar to the planned closure option although there have been changes to the schedule and other operational components since 1999. The 1999 closure case is shown in plan on Figure A.5.6.

A.5.3		Goals and Assumptions

		Tables A.5.1 to A.5.3 provide a summary of the environmental goals and assumptions associated with each general activity related to mine closure. The objectives are similar for the three plans considered as noted in the table. The goals relate to the cessation, decommissioning and rehabilitation of activities. Further details as to how the objectives apply in the three closure scenarios are discussed in Part B.

		Closure targets for the project elements and activities for both within and outside of the site mine areas will be determined during discussions between LMC, the government and local landowners between now and the actual closure dates.

Table A.5.3 Mine Closure Assumptions Stage 3 Planned Closure


ACTIVITY	OBJECTIVE		PROPOSED END USE AND PROGRAM
Staffing	• • •	Provide sufficient staff to monitor and maintain landforms. Maintain final land form for transfer to regulators. Ensure funds are in place and responsibility assigned for ongoing maintenance, if any.	• • • •	Minor works, clean up drainage works etc. Agree environmental and social monitoring program. Support community institutions. Undertake final site topography and bathymetry.

Balance date closure program would be as outlined in Table A.5.1 to A.5.3 above except:

	•		Kapit Village and Wild West stockpile do not yet exist. Kapit North and Kapit South stockpile will be relocated to the below water portions of the pit along with the Harbour Base stockpile.

	•		There will be extensive retrenchment and redundancies due to the unplanned nature of Balance Date Closure.

A.5.4		Rehabilitation Strategy

		Rehabilitation at the site involves the progressive rehabilitation of disturbed areas during operations and specific rehabilitation following Stage 1 and Stage 2 Closure or Balance Date Closure. The overall objective for rehabilitation is to leave the site in a physically and geochemically safe and stable condition.

		More specific goals however include:

	•		Securing excavated areas including pits and quarries;

	•		Ensuring adequate drainage and erosion control;

	•		Managing waste material including waste rock, tailings and contaminated soil;

	•		Promoting revegetation of disturbed areas as far as possible back to pre-mine vegetation types;

Page 36



Lihir Management Company Limited		December 31, 2004
Lihir Gold Mine — Mine Closure Plan Update 2004

	•		Where practical restore land for agricultural use;

	•		Minimising the adverse visual impact of the site; and

	•		Removing equipment, buildings and infrastructure, unless useful to the community.

		Disturbed areas as they are relinquished are progressively rehabilitated to establish a vegetative cover initially for erosion control and also to achieve long-term land use goals. Initial revegetation is by seed broadcasting of quick growing legume and grass species and where necessary, specific species are used to target specific problems. For example, in particularly erosion prone areas ‘fences’ of vetiver grass are planted and along foreshore areas, salt tolerant morning glory vines are used.

		Local species and other PNG indigenous trees are then planted, where appropriate, with an emphasis upon commercial nut and fruit trees. Natural recolonisation by local species tends to be swift and leads to the development of a self-sustaining productive ecosystem.

		Areas requiring rehabilitation are summarised in the Tables in Part B.

A.6		RISK MANAGEMENT

		Reference to Australian Standard 4360 (AS/NZ, 2004) describes risk management as the culture, processes and structures that are directed towards realising potential opportunities whilst managing adverse effects. Risk management is an integral part of good management practice and an essential element of good corporate governance.

		In recognition of this, a risk-based approach has been adopted during preparation of the updated closure plan to help identify and develop appropriate management strategies for the identified potential social, health, safety, environmental and economic impacts associated with the Lihir gold mine project commensurate with the proposed closure timetable.

		A summary of the identified potential impacts associated with the Bio-physical and Socio-economic aspects of the project are summarised in the following Tables A.6.1 and A.6.2 respectively. Proposed management strategies associated with each of the identified potential impacts and aspects are provided within Parts B and C of the updated closure plan report text. It is anticipated that a program of detailed risk assessments will be undertaken for each of the main identified potential aspects/impacts during future closure plan updates and once the identified action items described in Part D have been further progressed.

PART B ENVIRONMENTAL AND BIO-PHYSICAL CLOSURE PLAN

		The activities associated with the three stages of planned closure are outlined in this Part B and form the basis of the cost estimate detailed in Section B.7 and Appendix IV.

B.1		PLANNED CLOSURE — STAGE 1 END OF PIT OPERATIONS

B.1.1		Context

		LMC has identified sufficient reserves to sustain mining until the end of 2022. At the completion of mining, stockpiles of low-grade ore will be sufficient to continue milling and processing for a further 18 years until 2040. Stage 1— Pit closure will commence at the end of 2022 with the cessation of mining. Stage 1 is assumed to involve the closure and rehabilitation of the following mine components:

	•		The open pit mine and all associated systems;

	•		Most mining equipment and associated infrastructure; and

	•		Townsite Camp 1.

		The proposed schedule for Stage 1 and 2 planned closure is shown in Figure A.1.3. Stage 1 post closure monitoring program established as part of the Stage 1—Pit Closure will continue as shown on the figure, throughout the remaining project life, ending concurrently with the Stage 2 monitoring program in 2046. Again, Stage 1 monitoring is assumed to be part of normal operation and is not costed.

		Figure A.5.2 shows the expected general arrangement of the pit and associated systems at the cessation of mining at the end of 2022, together with the expected general arrangement of haul roads, low-grade ore stockpiles, process plant, and associated project infrastructure on the Site Mine Lease (SML) at the time. The area of land requiring rehabilitation by LMC’s operations in Stage 1 totals approximately 170 ha and is itemised in Table B.1.1.

		Components of the Stage 1 planned closure are summarised in Table B.1.1 with more details provided under cost estimates in Section B.7.

B.1.2		Closure Methodology For Stage 1

B.1.2.1		Plant Workshop, Mine Offices, Crib Hut, and Other Buildings and Miscellaneous Structures

		All equipment and facilities will be removed to ground level, concrete footings will be broken out as far as possible and covered with soil. Material for disposal will be sorted for contaminated or hazardous waste, cleaned if necessary and disposed in the open pit. Hazardous materials will be removed from site to an approved disposal area.

		Material of agreed usefulness, but not resold by LMC, will be stockpiled for recovery by the community. Material will be resold to third parties if possible, and if no other agreement is in place with the community, the closure estimate resale and salvage value is assumed to be nil. The plant workshop will remain but with reduced capacity to service equipment associated with low grade stockpile handling.

B.1.2.2		Barge Wharves

		The two barge wharves and associated facilities, tanks and services will be demolished, loaded on trailers and moved to the laydown area for sorting, dumping or recovery as outlined above. The foreshore will be graded, armoured and rehabilitated.

B.1.2.3		Screening and Dewatering Infrastructure

		The screening plant will be removed for storage, disposal, salvage or resale as described in B.1.3.1 above. Dewatering wells will have pumps, transformers and piping removed and will be backfilled or grouted and capped if above the final pit water level. Disturbed areas will be rehabilitated.

B.1.2.4		Heavy Equipment

		It is assumed 25% of the heavy equipment will be retained in service until 2040 to assist with low grade stockpile handling. Sufficient trucks will be retained for low grade stockpile hauling. Surplus equipment will be resold, salvaged, transferred to the community or cleaned and dumped in the pit.

Page 42



Lihir Management Company Limited		December 31, 2004
Lihir Gold Mine — Mine Closure Plan Update 2004

B.1.2.5		Pit Slopes

		The open pit will be flooded by sea water. For the planned closure scenario this would involve breaching the cofferdam around Kapit Pit. All potentially acid forming cofferdam material will be left below sea water level. A causeway of non acid forming (NAF) rock, complete with bridge or culverts to allow free flow of tidal water to the pit, will remain to provide access from Putput village to Kapit Village.

		Open Pit slopes will be graded as necessary, with drainage installed as final pit walls are developed. Rehabilitation is assumed to involve only areas above sea level and below the 1052 bench. Slopes above RL1052 are assumed to be rehabilitated as part of normal mining operations. For this area, topsoil will be spread on the benches, with seeding by broadcast or sprayer, planting saplings as required. Lime addition at a rate of $3,000 K/ha is assumed.

		It is assumed haulage of low grade material from the Wild West stockpile will occur along a bench purpose built as a haul road around the western side of the open pit, then running across a causeway past the harbour base to the plant site. Pit walls and drainage will be maintained as part of the operating haul road therefore no allowance is made for significant drainage or slope repairs on closure. Such repairs are considered an operating cost during low grade ore processing. It is assumed caldera drainage will be intercepted in a drainage channel to divert non contract water away from PAF pit walls as far as practicable and as planned under the MWSAMP, see Part A.

B.1.2.6		Low Grade Stockpiles

		There is no closure work for low grade stockpiles in Stage 1. As the stockpiles are removed during Stage 2 foot prints will be progressively rehabilitated. Rehabilitation costs are, however, included in Stage 2.

B.1.2.7		Town Site

		There will be a reduction in staff at end of pit operations but most town site facilities will remain. It is assumed Camp 1 will be decommissioned but other facilities will

B.2		PLANNED CLOSURE — STAGE 2 END OF MILL OPERATIONS

B.2.1		Context

		Stage 2 of the proposed program of closure will commence with the cessation of processing and run for about 2 years while the major decommission capital works occur. Stage 2 will involve the closure and rehabilitation of items outlined in Tables B.2.1 to B.2.3 and shown on Figure A.5.4.

		The main items are:

	•		Mill and Processing Plant decommissioning;

	•		Final Pit Closure; and

	•		Town Site and associated facilities decommissioned or transferred.

		The schedule for these items is included on Figure A.1.3. The critical path item is plant decommissioning which is shown to take 2 years.

		Tables B.2.1 to B.2.3 for the Plant, Open Pit and Townsite show the closure components, additional details are provided in the cost estimate tables in Appendix IV.

B.2.2		Closure Methodology for Stage 2

B.2.2.1		Plant Site

		The overall concept for building removal, hazardous waste handling, rehabilitation, disposal, salvage, distributions to the community are as planned for Stage 1 and discussed in Section B.1.

Page 49


Lihir Management Company Limited				December 31, 2004
Lihir Gold Mine — Mine Closure Plan Update 2004

		There are a number of underground structures, tanks, services tunnels and the like which will be removed and backfilled to smooth grades. Allowance has been made for a power line to Putput Village and to leave one switch room to service the power line.

B.2.2.2		Open Pit Mine

		Items remaining from Stage 1 include the plant workshop, plus the 25% of the open pit equipment fleet which was left to handle the low grade stockpile.

		The Wild West and Kapit Village stockpile footprints will be reclaimed while the remaining parts of the Kapit Coffer Dam embankment and Harbour Platform will be excavated to 2 m below sea level and surplus material dumped in Kapit Pit.

B.2.2.3		Town Site

		Items include the town site and related facilities including power generation, water supply, sewage, airports, roads etc. It is assumed 50% of the remaining townsite infrastructure will be demolished and the sites rehabilitated subject to negotiation with the community and regulators.

		The airport will be handed over to the Government. One pump and associated equipment will be left to provide water supply from Londolovit weir. The sewage treatment plant at the townsite will be maintained and handed over in operating condition. All roads will be repaired to design standards and handed over as-is to the community. The 6 MW power supply to Londolovit will be maintained and relinquished in operating condition. Miscellaneous quarries around the site will be regraded as required and seeded for growth as needed, although many minor quarries are showing unaided regrowth.

B.2.3		Kapit Village

		It is assumed Kapit Village will be re-established with 100 village style houses serviced with power and water as agreed following community consultations.

Lihir Management Company Limited				December 31, 2004
Lihir Gold Mine — Mine Closure Plan Update 2004

B.3		PLANNED CLOSURE — STAGE 3 — POST CLOSURE MONITORING

B.3.1		Context

		After the major decommissioning work is completed there will be a five year maintenance and monitoring period. During the period, compliance will be checked and once a stable condition is reached or at five years whichever is greater, the lease will be relinquished.

		It is assumed that a small maintenance crew will remain with some earth moving equipment or more likely this equipment will be hired locally. A crew of environmental monitors, community assistance officers and a small LMC management presence will remain. Immediately prior to handing over the property to the State, a comprehensive topographic and bathymetric survey will occur, so the transferred landform is documented.

		In addition, there will be a requirement for annual compliance reporting, possibly some miscellaneous design work to handle residual closure problems, and including equipment maintenance and upgrading during transition to final transfer.

		In many mine closures, a landform maintenance trust fund is established to allow the new owners to maintain the final landform. This landform maintenance trust fund is identified as a line item but with no cost at this time as it has been assumed to be included in the various post closure trusts identified in the Lihir SCDP discussed in Part C.

		The Stage 3 activities are discussed further in the sections below.

B.3.2		Monitoring Plan

		The aim of post-closure monitoring will be to demonstrate that the key environmental issues and targets identified during closure planning have been effectively managed by the closure program.

Page 51


Lihir Management Company Limited				December 31, 2004
Lihir Gold Mine — Mine Closure Plan Update 2004

Where appropriate, the post-closure monitoring will be based on the existing environmental monitoring program (EMMP) (e.g. the same sampling sites and sampling procedures will be used). However, some components of the operations monitoring program, such as the monitoring of atmospheric emissions, will no longer be applicable, and some additional monitoring will be required, such as water quality in the flooded pit. The monitoring effort in Stage 3 is assumed to be 30% of the current monitoring effort.

A summary of Stage 3 works is identified in Table B.3.1.

Lihir Gold Mine — Mine Closure Plan Update 2004

B.4		BALANCE DATE CLOSURE

		Balance Date Closure is set at December 31^st, 2004. A basic assumption is the Balance Date Closure will be an orderly event with an end result generally conforming to the end of mine landforms as intended after the Planned Closure as described in Section B.2. The assumed closed landform is shown in Figure A.5.5.

		Hence the balance date closure activities will include most activities in the Stage 1 to 3 planned closure. Due to the unscheduled nature of Balance Date Closure there are however some significant variations in work items assumed to be as follows:

	•		Wild West Stockpile, Kapit Village Stockpile and Kapit Pit do not exist at December 31, 2004;

	•		Kapit North, Kapit South and Harbour Base Stockpile will be relocated into Minifie pit; and

	•		An open cut channel will be excavated from Minifie Pit to the ocean to flood the pit.



		In addition to the physical works associated with Balance Date Closure, there are significant costs related to warehoused items, severance of contracts, redundancies etc. These liability items are not covered in this report.

B.5		SIGNIFICANT CHANGES SINCE 1999 CONCEPTUAL MINE CLOSURE PLAN (CMCP)

		Table B.5.1 shows a summary of the major changes since the 1999 CMCP. Since the 1999 plan there have been changes in legislation and corporate criteria, however, these have not radically impacted the closure strategy. The changes since 1999 are more related to changes in mine life and closure assumptions. Tables B.7.1 and B.7.2 show summaries of the impact of these changes to the estimated cost of closure.

B.6		COST ESTIMATE

B.6.1		Introduction

		Cost estimates are provided for the Planned Closures in Stages and for the Balance Date Closure. Previously estimated 1999 Closure Plan costs have not been checked and are taken directly from the 1999 report.

		The cost estimate is provided to LMC for budget purposes and no third party shall rely on the estimate unless directed to by written permission of LMC.

		The closure works will likely be done by a combination of local contractor and LMC workforce as such there will be highly variable indirect costs. Some elements will attract high accommodation, administration etc costs while local contractors may not carry large overheads. For the purposes of the current estimate, indirect costs are assumed to be a flat 50% of the estimated costs after contingency in Appendix IV.

		A 20% contingency has been allowed on capital work items for labour and materials. In addition, a global allowance of 15% has been included to cover LMC corporate costs and engineering design support during closure. The indirect cost allowance, contingency and corporate costs should be reviewed by LMC. No other risk allowance has been included.

		Detailed cost estimate work sheets are included in Appendix IV and show the assumptions, quantities, labour and equipment rates, productivities, crew sizes and the like. These have been developed with the assistance of LMC site staff.

		All estimates are done in 2004 Kina with no allowance for inflation or discounting.

B.6.2		Methodology

		The estimate was done using Microsoft Excel Spreadsheets. In general costs were built up from labour and equipment hourly rates agreed to with LMC. Closure items were broken down into small work packages and each of the packages assessed in

Page 55


Lihir Management Company Limited				December 31, 2004
Lihir Gold Mine — Mine Closure Plan Update 2004

		greater detail as to equipment requirement, crew sizes, productivity, required resources etc. based on current mine site experience.

		A unit rate of 24,000 Kina/hectare was provided by LMC for topsoil spreading and seeding.

		Crew and equipment compositions, assumed in the estimate, may not be the same as eventually used since the mine fleet and local contractor equipment will change over time. Similarly, no allowance has been made for future project expansions unless they are in the current mine plan, for example mill demolition assumes the current plant layout and expansion associated with the current Float Circuit Bankable Feasibility study is not included.

B.6.3		Basis of Estimate

		The cost estimate is based on the closure plans outlined in Sections B.1 to B.4. Generally if there is uncertainty in the work scope, a conservative position has been adopted (more expensive) in preparing the estimate such that further refinements in closure planning may result in lower rather than higher cost.

		Quantities were partly provided by LMC, while some were newly developed from “as built” drawings. A library of structural drawings showing details of buildings and facilities was prepared and studied in detail to help define the extent of closure and demolition.

		The primary cost estimator has been working on site for over a year and is familiar with local operators, contractor capability, logistical constraints and productivity.

		Labour and other costs were assumed to be current Lihir contract award rates.

		Equipment costs were current Lihir operating or contractor hire costs.

		No significant permanent new materials are required for closure so no costs were obtained from suppliers.

Lihir Gold Mine — Mine Closure Plan Update 2004

As summarised in Table B.5.1 there have been a number of significant changes to mine operations since the 1999 CMCP. These changes have increased the costs as shown in Table B.7.1 above. Changes include addition of Kapit Pit and the associated increase in low grade stockpiling (Kapit Village and Wild West stockpiles). In order to successfully excavate the ore from Kapit Pit and provide the necessary space for the resulting Low Grade Ore Stockpile (LGOS), Kapit Village will be relocated. Following closure and removal of the LGOS, Kapit Village shall be reestablished.

In addition to the direct costs for the above work, we have included an allowance for LMC and Contractor camp costs, administration and overhead by assuming indirect costs will be above 50% of the noted direct costs. Also an allowance of 15% for design and management is included. These items were not specifically identified in the 1999 CMCP. Overall these significant changes have resulted in a cost increase of over K150 million compared to the 1999 case. The costs are even more significant for the Balance Date Closure type condition if it were to occur at end of mining when stockpiles are at their maximum size.

A summary of major cost increases related to Planned Closure described in this report, compared to the 1999 CMCP costs listed in Table B.7.1, are shown in Table B.7.2

PART C SOCIO-ECONOMIC CLOSURE PLANNING

C.1		INTRODUCTION

		Part C of the Mine Closure Plan describes the social and economic issues and planning leading to closure.

		The socio economic closure planning strategy is designed to achieve a sustainable future for the Lihirian community, and is embodied in the Lihir Integrated Benefits Package (IBP).

		The IBP is a document which incorporates all of the commitments and benefits that the people of Lihir were promised in return for their agreement that the project proceed. The package provides an extensive range of benefits for all Lihirians. It includes assistance in the form of relocation housing, improved village layout planning, reticulated water and power supplies, and funding for social infrastructure development, such as roads, health and education.

		Following ongoing negotiations, the IBP has been recast as the Socio-Economic Development Plan (the Plan). The Plan builds on the IBP and is designed to provide a roadmap for a sustainable future for Lihirian communities. Periodic renegotiation of stakeholder agreements such as the IBP are an essential element of long term mining operations, if the relationship between landowners and the mine proponent are to be maintained. Such renegotiations can effectively adjust for agreement successes, unforeseen social and economic impacts, as well as provide a forum for relationship building as the project matures.

		It is acknowledged by all parties to the Plan that any realistic strategy aimed at sustainability will require the development of Lihirian capacity and capability for governance. This includes the Lihirian leadership, agencies representing the community and the community itself.

		If the operation closes in about forty years as currently anticipated, i.e. in 2040, the period leading to closure is the opportunity for the people of Lihir to build their own

C.2		SOCIO — ECONOMIC SETTING

		Since the 1980’s, the advent of exploration, construction and mining operations on Lihir Island have led to substantial change in the social and economic structure and wellbeing of the Lihirian community. Not all change has been positive or embraced by all Lihirians, but for most, the opportunity to benefit from the development is evident from the extensive participation in the mining project throughout the community.

		The Lihir group of islands comprises Niolam, Mali, Masahet and Mahur. The name Lihir (or Lir) traditionally refers to the language which is shared by the inhabitants of all these islands. For the purposes of this report, the term Lihir, will therefore comprise all the island group.

		The estimated population of Lihir is more than 13,000 people not including about 3,000 immigrant settlers. The population has more than doubled since the project began. As experienced at other projects in PNG, developments such as the Lihir gold mine are an attraction for non resident Lihirians to return home, and for non Lihirians from the PNG mainland and surrounding islands to participate in the perceived wealth generation activities, including employment and spin-off business opportunities.

		The Lihir population is spread among villages around the coast, with less in the more rugged parts of the island. Notably in the less accessible western and north-western areas. Villages close to the mine site (Putput, Kapit, Londolovit, Kunaye, Zuen and Malie) have been classed as Mine Affected Villages (MAV), and as such, receive direct benefits and compensation payments relating to social and environmental impacts from the mine development. Other communities indirectly affected also receive benefits.

		An influx of opportunistic settlers, including migrants from other parts of the country with no work arrangements and little or no technical skills, has led to increasing land and social pressures on the island. An estimated 3,000 immigrant settlers are now resident on Lihir Island.

C.3		LIHIR SOCIO-ECONOMIC DEVELOPMENT PLAN (SEDP)

		The SEDP (the Plan), also referred to herein as CSDP, is a comprehensive and complex document describing the interrelationships between a host of stakeholders including government, government agencies, committees, communities and LMC. The plan sets out to define how each of these groups will need to interrelate and perform, to maximize benefits, and sets out to redefine the distribution of benefit streams in a way that is equitable for the various beneficiaries. The following discussion summarises the intent of the plan in a closure planning context and is not a reproduction nor captures all of the necessary detail of such an important document.

		The Plan as described in this report comprises the following 10 elements:

	1.		Sustainable Community Development Plan (the Plan)

	2.		Land Use and Compensation

	3.		Community Health

	4.		Human Resource Development

	5.		Infrastructure

	6.		Community and Social Issues

	7.		Environment

	8.		Commercial Development

	9.		Specific Issues

	10.		Sustainability

The Plan has a 5 year planning and budget cycle. In an attempt to demonstrate the potential benefit streams resulting from implementation of the Plan, indicative revenue streams as planned budgets are estimated and presented for the budget cycle (2004 to 2008) based on LMC sourced projections. These allocations are discussed and shown in Table C.6.1 in Section C.6 of this report.

Lihir Gold Mine — Mine Closure Plan Update 2004

C.3.1		Socio-Economic Development Plan (the Plan)

		LMC has been reviewing the IBP with a negotiating committee representing the local level government and the Lihir mine area landowners since mid 2001.

		The original IBP was signed at Potzlaka Government Station on the 25th of April, 1995. The package represented the formal agreement of the people of Lihir to the start of the Lihir Gold project. The original document was formulated over a period of almost five years.

		The IBP is a document which seeks to incorporate all of the commitments and benefits that the people of Lihir were promised in return for their agreement that the project proceed. As well as the agreement between the community and the company, it also contains the agreements reached between the people of Lihir and the national, provincial and local level governments.

		The parties have agreed that the original IBP document needs to be substantially re-oriented to address the development needs of the people of Lihir over the period of the project. The negotiating committee has presented a paper entitled the Lihir Strategic Development Plan as their blueprint for the future of Lihir. This document introduces the concept of the Lihir Destiny, which sets the objective of being financially independent and self reliant both during and beyond the mine life.

		The Plan embodies the principles and agreements of the original agreement and incorporates the requirements of the negotiating committee. It is the principle output of the review process currently underway and represents a structure for the planning, implementation and monitoring necessary for a sustainable future.

C.3.2		Implementation of the SEDP

		The Plan has a five-year planning horizon, to be reviewed and updated annually, and is a joint commitment with the local level government to ensure that all money expended in Lihir is part of a single overall plan.

Page 67


Lihir Management Company Limited				December 31, 2004
Lihir Gold Mine — Mine Closure Plan Update 2004

C.3.2.1		Key Implementation Agencies

		At a local governance level, the key agencies and authorities with prime responsibility for implementation of the Plan include:

		Village Planning Committees — These committees are established under local level government reforms and are responsible for planning and regulating development in their respective communities. LMC intends to direct its community development budget through these planning committees. Each committee will have the authority to set expenditure priorities, and to identify new projects, within these annual budget allocations. The funds for the committee budgets are allocated on a per capita basis amongst the 15 local government wards, with specific allowances for the direct impact and indirect impact communities as appropriate.

		The funds include the Village Development Scheme funds, which have been allocated on a per capita community basis since 2001, and make up the bulk of the proposed annual ward budget. Additional funds are made available for the direct impact communities and a new element, the Quality of Life payment, recognises that the lifestyle of all Lihirian communities has been impacted by the advent of the mine. Further funds are provided to cater for community asset maintenance and for minor works in education and health.

		A guaranteed level of funding for the Village Planning Committees to manage on an annual basis is a first for Lihir and will place new demands on the members of the planning committees to deliver projects to the satisfaction of the community.

		LMC will fund a program of capacity building within the local level government to help with the implementation of the Plan.

		Ward Planning Committees (WPC) and the Local Level Government (LLG) — The projects and plans developed by the village planning committees are submitted to the ward planning committees and then to the local level government for endorsement and ratification.

Page 68


Lihir Management Company Limited				December 31, 2004
Lihir Gold Mine — Mine Closure Plan Update 2004

		Once the local level government approves the village planning committees initiatives, the approval is relayed to a Special Purpose Authority, which is responsible for project implementation. The Plan commits LMC to release funds to the authority based on this approval.

		Special Purpose Authority (SPA) — This body has been established by the local level government as an implementation agent for all local level government projects and activities.

		Nimamar Rural Local Level Government (NRLLG) — This government body is the only constitutional authority on Lihir. As such, the Plan calls for LMC to develop a sound working relationship and long-term partnership with the authority. LMC will provide resources and management expertise to assist the local level government to become a functioning and effective government for Lihir and an example for elsewhere in PNG.

Page 69


Lihir Management Company Limited				December 31, 2004
Lihir Gold Mine — Mine Closure Plan Update 2004

C.3.2.2		Planning Process

		Initial work has been done on developing a planning and implementation process based on the Village Planning Committee and Ward Planning Committee structure. The relationship between the key decision makers involved in the implementation of the Plan is shown below:

C.3.2.3		Monitoring and Evaluation

		A formal process of monitoring the ongoing success or otherwise of the various projects and programs is the key to the success of the plan. The Plan calls for a formal review process to ensure that the Plan is flexible and adapted to the changing circumstances on the ground, and in the community.

		While the long term program objectives and vision for the plan will remain in place, the annual program will change as needs are identified and agreed.

C.3.3		Land Use and Compensation

		Large amounts of money have been paid to the Lihir community since the project commenced as compensation for various forms of damage loss and inconvenience.

Page 70


Lihir Management Company Limited				December 31, 2004
Lihir Gold Mine — Mine Closure Plan Update 2004

		This was particularly the case during the construction phase. As levels of compensation have decreased with reduced levels of new activity, new ways and means of claiming and increasing compensation are needed.

		Land Use payments, which are provided to cover the surrender of access to traditional land for the period of the project, will continue for the life of the mine. As such, these payments are arguably more significant to the community than is compensation. LMC has proposed that compensation rates remain at the current (CPI adjusted) levels, but has offered a revised method of setting Land Use payment rates.

		This revised method takes into account population growth as a factor, as well as the annual CPI adjustment, which ensures that the payments remain consistent in money value terms over a period. To allow for the fact that the population, who is to share these payments, increases steadily over time, an adjustment factor to cover the past seven years will be made on a one off basis. The annual adjustment factor for Land Use payments thereafter will be the CPI (as determined by the PNG National Statistical Office), and an allowance for population growth of 2.2%.

C.3.4		Community Health

		Improved community health including health facilities and ongoing services, is one of the core expectations of the community as a result of the project going ahead. In the relatively short time since the hospital at Londolovit was opened, a noticeable improvement has been seen in many basic areas. In the main, these improvements have been in rates of child mortality, the nutritional status of women, and in malaria and filariasis prevention and control.

		The advent of the mine has brought health issues, as well as health benefits and a long-term health intervention strategy is required to manage all of these impacts on the community. The affects of the so-called ‘diseases of development’ are already starting to appear, e.g. heart problems and illnesses associated with diet and obesity are becoming widespread.

Page 71


Lihir Management Company Limited				December 31, 2004
Lihir Gold Mine — Mine Closure Plan Update 2004

		A major health program is already underway, with an initial focus on the communicable diseases that are currently most prevalent on Lihir, i.e. malaria, TB, and filariasis. These programs will be maintained to reduce or eliminate to the extent possible, the impact of these diseases. An ongoing program of interventions to deal with the issues for pregnant women and children will be maintained.

		A program to bring all of the facilities on Lihir up to the minimum standards as defined by the National Department of Health (NDoH) under the National Health Plan will be carried out. These standards represent a minimum that has not in fact been achieved in any health district in PNG. Each aid post and health sub centre will be upgraded so that the facilities will be physically adequate. A long-term program of selective upgrading over and above the minimum standards will be carried out depending on the requirements of each facility.

		Developing the quality aspect of the health service delivery system on Lihir will also be a major focus. The central health centre built by LMC will continue to function as a base facility for each of the government institutions and the medical centre staff will carry out periodic visits to provide a referral and technical support role. Training of staff at all levels will be part of the function of the centre, in conjunction with the NDoH and will be consistent with the policies and priorities of the National Health Plan.

		Development of local level capability will be implemented through the Lihir Health Committee, made up of representatives from the community and the company, and chaired by the local level government. The Lihir Health Committee will guide the development of health policy on Lihir, as well as dealing with local issues as they arise.

		Prevention is recognised as a more effective long-term policy than a simply curative approach, although the importance of the curative system must not be overlooked. A longer term program of improving the capability of local level institutions, and through ongoing community awareness and education programs will facilitate prevention rather than cure as the principal tool for dealing with health issues on a long-term basis.

Lihir Management Company Limited				December 31, 2004
Lihir Gold Mine — Mine Closure Plan Update 2004

C.3.5		Human Resource Development

		The Plan negotiating committee has expressed very clear views on the need to develop the capacity of Lihirians to manage their own affairs. The life of the project clearly represents the best, and perhaps the only opportunity, that Lihirians are likely to have to achieve this in any meaningful way.

		LMC understands and accepts this principle, and it will feature as a core objective of the Plan.

		A major component of the Human Resource Development component is to develop a program to reform the education system on Lihir. The International Education Agency of PNG will be retained to provide the technical management of a program that will upgrade the whole education system on Lihir. As with health intervention, there will be a program of physical upgrading of facilities, from village based pre schools through to the Primary schools.

		The International Education Agency (IEA) project manager will work with the Lihir Education Committee (LEC) and the National Department of Education and they will be responsible for upgrading the capabilities, and the quality of the delivery of education to the children of Lihir. A major review of the long-term requirements of Lihir in terms of education will be directed by the Lihir Education Committee and will provide the basis for the long-term plan. The Lihir Education Committee is to be chaired by the local level government and will comprise community and company representatives.

		The Company has instituted training programs for its Lihirian employees. These programs, which are primarily aimed at training people to work in the mining industry, will develop a cadre of technically trained manpower on Lihir that will have skills and experience that will be valuable in other mining projects, or in other industries, whether on Lihir or elsewhere in PNG.

		Training in job skills will be supplemented by adequate and suitable work experience to allow individuals to progress to supervisory or management levels. A number of

Page 73


Lihir Management Company Limited				December 31, 2004
Lihir Gold Mine — Mine Closure Plan Update 2004

		Lihirians have started on this pathway already, and the process will continue to ensure Lihirian participation in the mining project is maximised.

C.3.6		Civil Infrastructure

		Improved capital infrastructure was promised as part of the benefits to the Lihir community. The main item that has provided an immediate benefit to the community is the ring road, which was completed as a joint project by the National Government and LMC before the start of construction. Since that time, the road has been significantly upgraded, in particular the section from the airport to Palie via the mine site.

		The negotiating committee has prepared a program of infrastructure development covering the next five years. The priority areas established include the provision of permanent water supplies, drainage and sanitation, further extension of electrical reticulation and the maintenance and upgrade of the ring road.

		The Special Purpose Authority will have a key role to play in the planning, design and implementation of these projects. This will ensure that the capacity for implementing such works is developed on Lihir as part of the local level government system. LMC will provide technical support (and finance) to facilitate this process.

C.3.7		Community and Social Impact Issues

		Development on the scale of the Lihir project generates an enormous impact on the local community. Much of this impact is beneficial, in terms of increased incomes, jobs and better health and education facilities. However, there is also a negative aspect, as people become far more money minded, and traditional attitudes and relationships change along with the focus on cash. The influx of migrants from other parts of PNG brings new ideas and behaviour patterns that are not always an improvement on traditional behaviours.

		The Company recognises that these changes create stress within the community. A Social Impact Committee has been established, and it will take the lead role in defining such issues, and in the design and implementation of program to minimise

Page 74


Lihir Management Company Limited				December 31, 2004
Lihir Gold Mine — Mine Closure Plan Update 2004

		negative impacts. One such initiative has been the introduction of the Peace Foundation Melanesia, which is working with communities on Lihir to facilitate dispute resolution without conflict.

		LMC has also established a Social Monitoring and Research section within Community Relations. This is a first for PNG and it provides LMC with professional guidance and analysis on community issues. The Social Monitoring and Research section will work closely with the local level government Social Impact Committee and will provide a secretariat to that body.

		Under the overall scope of this program, there will be individual projects that address the needs of sports and recreation, women, youth and spiritual development.

C.3.8		Environment

		There are two distinct components to the environmental monitoring and management program operated by LMC. The first is the technical aspect, which is covered by the requirements of the PNG government, as well as by the standards of Rio Tinto and the World Bank. There is a substantial quantity of scientific study and analysis already available on the environmental impact of the project, dating back to the baseline work carried out in the 1980’s and 90’s.

		The technical monitoring and ongoing research will continue as the basis for the reporting LMC is required to provide to the Government of Papua New Guinea, Rio Tinto and the International community.

		The Plan requires that all reports, and the results of all research work carried out, be made available to the Lihir community, and its representative agencies. As these are technical reports, however, it is acknowledged that they do not always answer the concerns of the community in language that is readily understood. The information will be provided in translated form, again to the extent that is feasible given the technical nature of the information.

		To address this issue of communication and understanding, the Company has commissioned a sociological survey to define exactly what the perceptions of the

Page 75


Lihir Management Company Limited				December 31, 2004
Lihir Gold Mine — Mine Closure Plan Update 2004

		community are, in terms of environmental impact and issues, and how best to answer those concerns in a way that will be culturally appropriate, communally comprehendible and personally credible for the community.

		A key to this will be to develop the involvement of more Lihirians in the monitoring program itself. This has been initiated by the establishment of a Lihirian staffed company that will carry out field survey work on a contractor basis. LMC also seeks to identify suitable Lihirians to study environmental science and related disciplines.

		LMC recognizes that excellence in environmental management and an open partnership with the community are essential to the success of the mining operation, and the long-term relationship with the community. The Plan commits LMC to the following actions:

	•		Consult with the community to share information and listen to their concerns and expectations.

	•		Develop and implement an integrated social and environmental management system to facilitate sustainable and ongoing performance improvement.

	•		Maintain environmental and social monitoring programs and report the results in a clear and transparent manner.

	•		Comply with applicable PNG environmental laws and regulations as well as corporate standards and guidelines and, where these do not exist, adopt internationally recognized standards of best practice.

	•		Minimise the amount of waste generated and optimise the use of natural resources.

	•		Participate with government and industry organizations in further development of social and environmental policies, codes and practices aimed at improving performance.

C.3.9		Commercial Development

		Significant expenditure and activities during the construction period facilitated a multitude of private business opportunities. As the project matures and the level of commercial activity decreases, the availability of viable commercial opportunities has decreased.

Page 76


Lihir Management Company Limited				December 31, 2004
Lihir Gold Mine — Mine Closure Plan Update 2004

		LMC remains committed to fostering the development of a sustainable business sector on Lihir. Where mine contracts can be provided to local firms on a proper commercial basis this will continue to be done, but at the same time, there is a need to identify viable opportunities that are not dependent on the mine.

		Currently, all business is dependent on the mine for its existence. In the Lihir Strategic Development Plan, the negotiating committee recognises this as a weakness and has incorporated a Lihir Economic (Non Mining) Development Action Plan into the document. The Plan aims to actively develop a commercial sector on Lihir that is not dependent on the mine to provide for the post mine period. This is a long-term program, and the opportunities created by the mine need to be used wisely to enable the transition. LMC will work with the community, within its own Commercial Development policy, to facilitate this objective.

		A new Contract Administration section is now functioning within LMC to ensure that the processing and award of all contracts is done in a transparent and fair manner. The Commercial Development Office (CDO) of LMC will be involved to ensure that community issues are taken into account in the tendering and award process.

		To help facilitate the start up of new businesses, or the growth of existing ones, increased funding will be provided under the Interest Free Loan Scheme managed by the CDO. The amount available will be increased from K200,000 to K750,000 and the amounts available to individual business applicants will increase from the present K5,000 limit. This will be a revolving facility which will need to be paid back to ensure the maximum availability of new finance for Lihirian businesses.

		The Commercial Development Office will continue to provide administrative and logistic support to those businesses that seek it, and will continue to assist with project development and commercial evaluations on request.

		Training for Lihirians in various aspects of business administration and financial management will also be provided in conjunction with government agencies, on a regular basis.

Page 77


Lihir Management Company Limited				December 31, 2004
Lihir Gold Mine — Mine Closure Plan Update 2004

		The key to LMC’s business development policy for the next five years, (and beyond), is to build on the existing business development base to develop a viable, self-sustaining business community, with a minimal dependency on the mine.

		LMC’s Business Development Policy is clearly intent on meeting these objectives:

“LMC will work closely with the community of Lihir to develop a business sector that is commercially viable, and self sustaining. Dependence on the operations of the mine is acknowledged as unavoidable for the time being, but a key objective of LMC will be to encourage diversification, both on Lihir and elsewhere in New Ireland and PNG.

The company will work closely with those businesses and entrepreneurs who are prepared to work with the company to develop business plans that are realistic and achievable.

LMC does not want to be a party to ‘white elephant’ schemes that only disappoint.

LMC also commits to working closely with interested and appropriate agencies,(e.g. government), to provide training and technical support to small Lihirian businesses that require it.

LMC will work through the Lihir Business Development Advisory Committee (LBDAC) to guide the process. The role of the LBDAC is to be refined and formalised.

The financial support that LMC provides will be increased, and the guidelines, (through the LBDAC) will be clearly spelled out. The principal focus will be on small and medium sized enterprises to maximise the number of Lihirian businesses that benefit.

All businesses that LMC assist will have to recognise that normal commercial principles MUST apply if any particular business is to be successful. LMC will not subsidise inefficient operations.”

C.3.10		Specific Issues

		There are three subsidiary agreements within the original IBP that address specific community issues. These issues relate in the main to the Relocation community, the

Page 78


Lihir Management Company Limited				December 31, 2004
Lihir Gold Mine — Mine Closure Plan Update 2004

		Plantsite community and the Londolovit community. The Plan recognizes that circumstances have changed and that the agreements need modification.

C.3.10.1		Relocation Agreement

		The actual relocation phase has now been completed, but there are ongoing issues and responsibilities that LMC has toward those people that were originally relocated, and their direct descendants.

		A separate sub agreement will be prepared to clarify the arrangements that will be in place to deal with the needs and concerns of the original relocatees and their direct descendants. Issues of a general community development nature, i.e. those which impact the community as a whole, will be catered for under the arrangements referred to earlier under the Plan. The special Community Development Fund provided for under the original Putput Community Agreement will be maintained, but incorporated into the proposed annual ward allocation.

C.3.10.2		Plantsite Agreement

		The Plantsite issues are covered under the main IBP agreement, although the operation of the Plantsite Trust Fund will require special attention. Responsibility for the operation of the trust fund rests with the Board of Trustees appointed under the original IBP agreement.

C.3.10.3		Londolovit Community Agreement

		This agreement deals with community development issues, in particular the development of the Londolovit plantation area and the involvement of the traditional land owners in that process.

		The funds that have been provided for community development under the earlier agreement will now be incorporated into the ward budget structure. It is further proposed that the Londolovit River Community trust be amalgamated with the Londolovit Landowners Trust Fund to simplify their operation.

Page 79


Lihir Management Company Limited				December 31, 2004
Lihir Gold Mine — Mine Closure Plan Update 2004

		Acknowledgment of the proximity of these three communities to the physical presence of the mine, and therefore a greater level of physical and social impact is reflected in the sliding scale under the Village Development Scheme allocation, and the ‘Quality of Life’ community compensation proposal.

C.3.11		Sustainable Development and Closure (The Lihir Destiny)

		The common theme of the Plan and that of the negotiating committee is financial independence and self reliance for a future Lihirian society. It is recognised by all parties that appropriate and necessary infrastructure and services for the community needs to be provided at a level and standard that will be able to be maintained once the mine closes.

		Any meaningful or realistic measure of sustainability requires the development of Lihirian capacity and capability for governance from the agencies representing the community; i.e. the local level government and the Special purpose Authority it has established.

C.3.11.1		Post Mine Provisions

		A Long Term Investment Fund was included in the IBP, virtually as an afterthought to the process. It was agreed that LMC would pay an annual sum of K 10,000 into this fund, but no discussion took place on any detail relating to this fund, how it should be managed, and what exactly it was providing for.

		No formal trust instrument was prepared, largely because of a lack of clarity to intention, but the annual payments have been made, and a sum of some K130,000 is currently on deposit under this provision. It is proposed that this amount be used as a starting contribution to the more substantial long-term provisions proposed hereafter.

Page 80


Lihir Management Company Limited		December 31, 2004
Lihir Gold Mine — Mine Closure Plan Update 2004

LMC propose to establish three new, separate funds for the long term i.e. post mine, situation. They will be focussed on providing funds to maintain the operation of the infrastructure in three key areas:

	•		Health

	•		Education

	•		General Infrastructure Maintenance

		An amount of K100,000 per annum for each of the above areas, i.e. K300,000 per annum in total, will be placed into a long-term investment fund, under the control of a professional fund manager.

		An Investment Board shall be established to monitor the funds to ensure that the fund manager adheres to the investment policy laid down by the board and as amended over time. The funds would be under the control of the fund manager, and would be invested overseas (as well as in PNG at the discretion of the manager). The fund would be maintained in US dollars to ensure value is sustained.

		Membership of the Board will include LMC, Nimamar Local Level Government, the New Ireland Provincial Government, the Lihir community, Department of Mining and the Department of Treasury.

		It will be a requirement that the Board submit an annual report to constitutional agencies including the Nimamar Local Level Government, the New Ireland Provincial Government and the PNG Minister For Mining.

		It is the expectation of the company that the Nimamar Local Level Government or its successor, will be responsible for the management and control of all community assets post mine, and so the funds from the trust will be released through the Nimamar Local Level Government and Special Purpose Authority, or whatever legally constituted successor agency is in place to fulfil the function of local governance.

Page 81


Lihir Management Company Limited		December 31, 2004
Lihir Gold Mine — Mine Closure Plan Update 2004

		Nominations to the Board should be reviewed regularly, at least at the time of each project review, i.e. every five years.

		It is not expected that these funds will be accessed during the life of the mine. They will be accumulated to provide a substantial capital sum. This fund will be available to the community at mine closure to ensure that the facilities and services they have come to expect will continue to be available.

		It is not possible to provide for an indefinite period. This arrangement acknowledges the need to provide in a significant and meaningful way for the post mine situation at this early stage. The adequacy of the provision will be able to be monitored over the course of the project life.

		Should the community decide to direct a percentage of royalty payments and/ or dividends into these funds, it will of course boost the amount available at project closure. No assumptions are made about the capacity of the Government, either National or Provincial, to contribute to this provision, or to provide support funding and personnel at the end of the mine life. Whatever is available will be in addition to the trust fund provisions, and will therefore be a bonus.

		This provision is not intended to provide funds for capital expenditures. They are for the purpose of maintaining services and maintaining community assets that exist at the closure of the mine. They are not intended to cover any costs associated with the closure of the mine itself, nor of mine related assets which will be provided for independently as part of the mine closure planning process.

		An independent fund manager will control and manage the funds. The Investment Board previously mentioned will oversee the investment of the funds.

		The Investment Board will guide the fund manager, and receive and endorse the annual report from the manager, as well as the audit report.

		This board will not be authorised to draw down on the funds, except to pay legitimate expenses of administration, until the formal surrender of the Special Mining Lease from LMC to the Government of PNG.

		The funds will then be available, (but not as a lump sum payment) to the Nimamar Local Level Government, or its successor, to pay the annual costs of maintaining and running the health, education and other social service programs, (but not salaries of public servants), and the maintenance and upkeep of civil infrastructure, such as roads, bridges, electricity supply etc.

		These funds will not last forever, but they will provide a substantial reserve to allow for a period of phased reduction in activity after closure. It is impossible to gauge the degree to which national government finance will be able to contribute to this requirement at this point in time, but clearly any contribution that they can make will assist the process.

C.5 PNG GOVERNMENT SUSTAINABLE DEVELOPMENT POLICY

		In 2002 the PNG Department of Mining (DoM) convened a National Steering Committee (NSC), to oversee the development of a Sustainable Development Policy and a Sustainability Planning Framework for PNG’s mining provinces. The development of a policy and planning framework was considered necessary to guide provincial and local level governments, mine-affected communities and resource developers in making sustainable investment decisions on the use of the remaining mining benefit streams in the lead up to and after closure.

		The following summary outlines the principal recommendations of the policy documentation:

	•		all mining project area stakeholders (including the developer) are required to participate in the development of a Community Sustainable Development Planning (CSDP) process;

	•		resource developers are required to provide the CSDP partners with specific information on benefit stream projections and the company initiatives to support social and economic development throughout the whole of the mining project cycle;

	•		Special Purpose Authorities (SPA) are to be established in each project area to assist in the design, implementation and monitoring of the CSDP;

	•		A Sustainability Planning Division would be established within the Department of Mining to assist in the design and monitoring of CSDPs and the coordination of national government inputs;

	•		Special Support Grant payments would be progressively abolished and replaced with a more flexible approach for the use of the Tax Credit Scheme.

C.5.1 Community Sustainable Development Planning

The DoM proposes to establish a process of Community Sustainable Development Planning (CSDP) for all major mining projects. It is proposed that the CSDP:

•

be a plan for the sustainable development of mine-affected communities or project area communities through the different stages of the mining project cycle;

Page 85


Lihir Management Company Limited		December 31, 2004
Lihir Gold Mine — Mine Closure Plan Update 2004

	•		be formally integrated with the provincial, district and local-level planning and budgeting process in the host province under the joint supervision of the Department of Planning and Rural Development and the Department of Mining;

	•		be a multi-stakeholder process involving all of the primary stakeholders involved in the development of a major mining project. (the national government, the provincial government, the project district and LLG, project area communities, civil society groups and the mining company).

	•		be coordinated by the national government through a Development Planning Committee (DPC) for each major mining project area.

		It is proposed that the CSDPs should be a rolling 5-year plan which is subject to annual review and should also be based on a budgetary process which clearly matches planned expenditures with forecast revenues.

		Developers will be expected to provide specific inputs to the process which are either based on its own plans and projections or on its commitments under the Mining Development Contract, the Development Forum, or an approved Environmental Impact Statement. These specific inputs are listed below:

	•		A rolling 5-year forecast model of the total amount of revenue which is expected to accrue to the Project Area, based on projected mine output, project commodity prices, and the benefit-sharing agreements which have been negotiated through the Development Forum;

	•		A rolling 5-year plan for expenditures within the project area under the Tax Credit Scheme, including a justification for such expenditures;

	•		A rolling 5-year forecast of the amount of revenue which is expected to accrue to a host provincial government, for use outside the mining project area, and plans for any Tax Credit Scheme expenditures made outside the project area (but within the province), in order to inform the relevant provincial, district and local-level plans.

	•		Business development plans, training and localisation plans,

	•		Special provision for relocation and resettlement plans, food security plans, AIDS awareness plans and any other plans for the management of community affairs which are intended to benefit or support project area communities;

Page 86


Lihir Management Company Limited		December 31, 2004
Lihir Gold Mine — Mine Closure Plan Update 2004

	•		Environmental management plans produced in accordance with the permit granted by the Director for Environment and Conservation; and

	•		Mine closure plans required under the terms of the government’s Mine Closure Policy.

C.5.2 Tax Credit Scheme and SSG

		DoM proposes that expenditures controlled by developers under the Tax Credit Scheme should be progressively converted into tax-creditable Development Levies during the operational life of a major mining project. This means that the developer as part of a multi-stakeholder Development Planning Committee would have the flexibility to convert tax credits into development levies which could be used by a provincial or local level government to support infrastructure development, maintenance, capacity building and Trust Fund accumulation.

		It is proposed that this arrangement be known as the ‘Tax Credit Conversion Scheme’, and that Development Levies paid under this scheme to local-level governments or their instrumentalities should also be managed in accordance with a Community Sustainable Development Plan.

		In terms of mine closure on Lihir, the Tax Credit Conversion Scheme would provide both the NIPG and the Nimamar LLG with an additional source of revenue to support Trust Fund accumulation.

		The DoM believes that Special Support Grants to provincial governments which host a major mining project should be removed as soon as possible. Grants of this kind can only be justified during a mine’s construction phase, or during a transition phase following mine closure. The DoM recognises that the sudden elimination of Special Support Grants currently paid to provincial governments in respect of existing projects will have a dramatic effect on provincial plans and budgets. There are two options for mitigating this negative impact:

•

Special Support Grants could be removed in stages over a period of 3-4 years, in much the same way that the national government is

Page 87


Lihir Management Company Limited		December 31, 2004
Lihir Gold Mine — Mine Closure Plan Update 2004

already committed to removal of the Mining Levy imposed on the industry.

•

Immediate withdrawal of Special Support Grants could be offset by an allowance for developers to spend an additional 0.25% of their gross revenues on Tax Credit projects for the benefit of the provincial population resident outside of the mining project area.

The second of these options would have the effect of raising the standard limit of Tax Credit expenditures in the host province to 1% of the developer’s gross revenues.

C.5.3 Integration of Sustainable Development Policy and Mine Closure Policy

The DOM does not propose the establishment of a Mine Closure Planning process to run parallel to the Community Sustainable Development Planning process as it could lead to a waste of time and resources for all parties. The intent is to convert the process of Community Sustainable Development Planning to a mine closure planning process at a predetermined time in the mining project cycle and maintain the continuity of the DPC or a reconstituted Mine Closure Planning Committee to assist in the development of the mine closure plan.

C.5.4 Premature Closure

		On the issue of premature mine closure, the DOM notes that there should be some avenue for communication between the national government and the operators of a major mining project about contingency plans for ‘premature closure’ resulting from the incidence of civil unrest in the project area. The Department is aware that this issue may not be suitable for inclusion in a multi-stakeholder planning process, but that a contingency plan still needs to be developed as part of an overall Mine Closure Policy.

		In summary, the proposed DOM policy and planning framework has significant implications for sustainable development and mine closure planning on Lihir. Under the policy, LMC will be required to be an active participant in the preparation and development of a Community Sustainable Development Planning process covering the whole of the mining project cycle including preparations for mine closure.

C.6 MINE REVENUES AND DEVELOPMENT FUNDING

C.6.1 General

		The SEDP has a number of revenue streams to fund the activities described earlier in this section of the report. The funding streams are a combination of mine generated revenues, Government and land owner payments.

		The SEDP revenue streams are planned on a 5 year rolling budget cycle as described in Section C.3. Government and land owner funding is closely tied to mine production and as such depends on actual mine performance predicted by the mine plan. For planned closure as described in Section B, these revenue streams are intended to provide funds to provide a platform to assist with the long term sustainability of the Lihir communities.

		These funds do not constitute a closure cost since they represent a cost of doing business. When the mine ultimately closes, the mine related revenue streams are assumed to be phased out. The accumulated funds in the various Trusts described in Section C.3.11.1 are expected to provide a platform for the maintenance of health and education services and the maintenance of community assets after the mine closes.

		Costs dealing with the possibility and risks that the planned funds are not sufficient at closure are not dealt with here.

		This section briefly outlines the 5 year budget cycle anticipated revenue contributed by LMC, Government and local funding based on the Lihir Socio-Economic study (Project Design and Management 2003). The 5 year planned revenues are the subject of on-going negotiations but are expected to reduce over time and cease at the end of the mine life.

C.6.2 LMC Contributed Revenues

LMC generated revenues for the period 2004 to 2008 as listed in Table C.6.1.

Page 89


Lihir Management Company Limited		December 31, 2004
Lihir Gold Mine — Mine Closure Plan Update 2004


Table C.6.1 —		Lihir Sustainable Community Development Plan — LMC Contributed Revenues


CLOSURE PLAN SECTION	DESCRIPTION	PERIOD 2004 TO 2008 KINA

C.3.1	Plan Management and Implementation including Village Development Fund	29,035,000
C.3.3	Land Use and Compensation	32,600,000
C.3.4	Community Health	16,500,000
C.3.5	Human Resource Development	5,460,000
C.3.6	Civil Infrastructure	21,150,000
C.3.7	Community and Social Impact	3,815,000
C.3.8	Environmental Monitoring	1,400,000
C.3.9	Commercial Development	7,750,000
C.3.10	Specific Issues	1,655,000
C.3.11	Post Mine Provisions	4,775,000

	Total	124,140,000

		The period leading to planned closure in 2040 will provide for a continuance of funding for the items listed in Table C.6.1 with a likely reduction in annual funds available as the mine matures and the operating emphasis changes from pit operations to milling. Notwithstanding the planned reduction in LMC contributed revenues over the course of the mine life, the substantial investments made available to the CSDP, will assist with the transition to sustainable development and self reliance as an attainable goal for the Lihirian community.

		In addition to these revenue streams, the post mine provisions discussed in Section C.3.10.1 have an annual guaranteed funding level of K300,000 equally allocated between three long-term investment funds i.e. Health, Education and General Infrastructure Maintenance Trusts. Assuming these funds were invested over the term of the mine (40 years), adjusted for CPI increases (2.5%) and earned 6% compound interest, the future value would exceed K60 million. Additionally, and by way of example, should the annual investment be increased to K1,000,000 with additional land owner funds, the return would exceed K160 million. Clearly, an opportunity exists to capitalise on surplus revenue streams during the life of mine guaranteeing access to funds for the future.

Page 90


Lihir Management Company Limited		December 31, 2004
Lihir Gold Mine — Mine Closure Plan Update 2004

However, under the Balance Date closure scenario, the funding is assumed to be rapidly phased out following the Balance Date.

C.6.3 Government Funding Sources

		Table C.6.2 lists funds available from Government sources. The State returns a portion of the collected Royalties and Taxes (in the form of Special Support Grants and Tax Credits) to the New Ireland Provincial Government and the local level government on Lihir. The local level government obtains further funds from equity (share ownership) in LGL. The items in Table C.6.2 below are those which directly flow to Lihir. There are other benefits flowing to New Ireland Provincial Government in addition to these.

		The items listed in Table C.6.2 depended on the financial performance of LGL. As such the value of these items is set by achieved production and by the stock price and dividend payments associated with company operations.

		Continued successful operation or improvement in operation would maintain the SSG, Royalties and Dividends at close to current levels. Equity will depend on external market fluctuations and valuations.

		These revenue sources will effectively cease on cessation of production. The revenue sources would also cease on the Balance Date Closure date.

C.6.4 Lihirian Wages

At December 2004, about 390 Lihirians were employed on a full time basis with LMC. A Lihirian salary averages about K25,000 per annum. Assuming a 15% increase in Lihirian employee numbers during the next five years, this would bring the number of Lihirian employees in 2008 to about 450 with an annual income totalling some K11,250,000.

During the five year budget cycle of the CSDP, the Lihirian wage income would approach K50,000,000 for the period.

In addition, about 70% of the contractor workforce of about 1,900 are Lihirians. Assuming an annual income of K15,000, this equates to an annual income of about K20,000,000 in total or over the five year budget cycle about K 100,000,000.

These income data show a Lihirian income per capita of about K23,200 compared to the National average of K2,000.

C.6.5 Available Funds

		Funds currently available over the next 5 year period are summarised on Table C.6.3.

		These funds will decrease when open pit mining ceases and the area of disturbance reduces. Mine revenue related funds, SSG, royalties, equity etc. will continue through to mill closure 2040, but at a rate dependent on mine production and gold price fluctuations.

		If the mine enters a Balance Date type closure most of these funds would cease on the Balance Date.

C.7		MINE CLOSURE ISSUES AND IMPACTS

C.7.1		Introduction

This section outlines the socio-economic issues and impacts that can be expected from closure of the mine. As detailed in Part A, planned closure includes Stage 1 Closure (2022) which signifies the end of pit operations and Stage 2 Closure (2040) which represents the end of mine operations.

To conform with general accounting practice, a Balance Date Closure at 31 December 2004 in which closure liabilities at end of 2004 are estimated, is also presented.

Table C.7.1 displays the employee numbers for the workforce including LMC employees and contractors for balance date and planned closure (Stage 1 and Stage 2).

Planned Closure — Stage 1 (2022)

The end of pit operations is scheduled for the end of 2022 at which time Stage 1 Closure will occur. Pit mining and waste rock disposal will cease and milling operations will continue to process stockpiled low-grade ore until 2040. The site arrangement in 2022 is shown on Figure A.5.2. Stage 1 closure will involve flooding

Table C.7.2 Planned Closure — Stage 1 (2022) Socio Economic Impacts and Issues


Area of Impact	Impacts and Issues	Comments
Employment	• Reduced employment opportunities particularly mine contractor staff associated with local businesses.	• Opportunity for diversion of pit contractor workforce to ore stockpile reclaim and transport work.
	• Pit operations FIFO staff repatriated with reduction in support services.	• Refer to Table C.7.1 for employee reductions.

Local Businesses	• The requirement for support services will be affected with the potential for contract work being reduced. • Refer to Table C.7.4 for the types of services affected.	• An opportunity exists for local businesses to adsorb a greater equity in existing JV’s between now and 2022. This would likely offset contract staff reductions.

Training and Education	• LMC training effort redirected to required mill process training requirements. • No impact on education facilities or services.	• Sustainable Community Development Plan support for long term education facilities and services.
		• Accelerate Lihirian training and skilling prior to Stage 1 closure to maximize Lihirian workforce.

Health Services	• No impact on health services for Lihir communities.	• Sustainable Community Development Plan support for long term health facilities and services.

Population	• Increased population pressures due to improved birth rates and health facilities. • Loss of employment will have some affect on cash incomes in the Lihirian community due to assimilation of migrant population.	• Sustainable Community Development Plan support for alternate business opportunities leading to Stage 1 closure may ameliorate increased social pressures.

Standards of Living	• Loss of earnings will result in some decline in standards of living for a part of the Lihirian community.	• Health, education and government services will be maintained due to Sustainable Community Development Plan.
	• Land pressures will limit additional subsistence gardening opportunities.

Police and Court Facilities	• No likely impact and all services maintained at appropriate levels.	• Sustainable Community Development Plan support for long term government services.

Emergency Facilities	• No likely impact and all services maintained at appropriate levels.	• LMC operations require maintenance of emergency services.

Utilities	• No likely impact to water, sanitation, rubbish disposal, drainage or communications.	• Sustainable Community Development Plan support for long term utility services.
	• Some reduction likely in power reticulation requirements.

Transport	• Some reduction in transport requirements due to reduced workforce.	• Excess vehicles may be available for resale to the community.

Environment	• Increased population at 2022 will place additional pressures on land clearing for subsistence activities.	• LMC environmental awareness programs aimed at mitigating ongoing environmental pressures.

C.7.3		Planned Closure — Stage 2 (2040)

C.7.3.1		General

Processing of low grade ore is expected to be completed in 2040 at which time Stage 2 Closure will be implemented. Plant site closure will involve removal and decommissioning of plant site buildings, infrastructure and the transfer of various assets to the local level government, National Government or the community as the site is relinquished. Closure activities will include remediation and revegetation of the decommissioned areas.

Unwanted buildings in the town site are to be demolished and the remaining buildings transferred to government or to the local community. Kapit Village will be re-established. Stage 2 Closure is discussed in Part B and illustrated on Figure A.5.4.

The closure works period is expected to last two years followed by a further five year post closure monitoring period to 2046.

Stage 2 Closure representing an end to the project will have a significant and profound impact on the Lihirian community. By the year 2040, as many as five generations of Lihirians would have participated in the project either directly or indirectly.

The socio-economic issues and impacts expected with Stage 2 Closure are summarised in Table C.7.5.

Lihir Gold Mine — Mine Closure Plan Update 2004

Table C.7.5 Stage 2 Closure (2040) Socio Economic Impacts and Issues


Area of Impact	Impacts and Issues	Comments
Employment	• All non Lihirian and expatriate employees repatriated to place of origin. • Significant numbers of Lihirians cease employment with little opportunity to continue with meaningful work on Lihir. • A small number of employees and local businesses will be needed for the rehabilitation and monitoring phases of closure.	• Under the Sustainable Community Development Plan (SCDP) , there are a set of Operational Trusts and Long Term Investments to help provide support for sustainable community development after mine closure.

Local Businesses	• The requirement for the majority of support services would cease. • In the absence of contracts with LMC, most local businesses would be affected. • Businesses servicing ongoing local demands — such as village trade stores, vehicles and small boat transport will continue.	• Refer to Table C.7.4 for the types of services affected. • Potential opportunity for contract work and support services to complete closure, including maintenance and monitoring. • Alternative business opportunities created during the life of mine may provide ongoing employment and incomes on Lihir.

Training and Education	Training • LMC training activities will cease. • The workforce will no longer be required and the need for the associated technical skills that the apprenticeship and technical training provided will cease. • Potential opportunities for additional training in the post-closure maintenance and monitoring period (Stage 3). • Potential opportunities for training in the management and maintenance of certain utility facilities planned for transfer to the local community. May include the power generation, water supply and treatment facilities. Education • By 2040, there is expected to have been significant development in education services (including the community, primary and high schools) • Final Closure is thus unlikely to have a major impact upon the delivery of the educational services.	• Sustainable Community Development Plan support for long term education facilities and services. • Through the current training programs, LMC will have trained many Lihirians by 2040, in a range of basic and technical training • LMC will assist Lihirians in gaining employment elsewhere after mine closure through targeted training programs. • LMC will identify potential training opportunities for utilities to be transferred to the government and local communities • Under the SCDP, LMC will have supported the effective delivery of the national educational reforms across Lihir.

Table C.7.5 Stage 2 Closure (2040) Socio Economic Impacts and Issues cont’d


Area of Impact	Impacts and Issues	Comments
Health Services	• The development of the health services on Lihir is expected to be significantly improved compared to the situation prior to the mine development. • It is expected that there will be a robust health care infrastructure and management system in place to deliver efficient and effective services following mine closure.	• Sustainable Community Development Plan support for long term health facilities and services. • Provision of improved health and health care services on Lihir is one of the major benefits expected from the mine development. • The Government will be responsible for the management and maintenance of Lihir’s health care system after mine closure.

Population	• End of employment at the mine and support services will result in a reduction in populations. • Projections include 2% long term population growth for Lihirian communities. This equates to unsustainable populations approaching 30 000 by 2040. • In-migration by people seeking work at the mine or other local businesses will reduce. • Exodus of people expected to other parts of PNG to look for employment opportunities and in particular those skilled workers who have received education, training and scholarships through their association with the mine and the educational and training programs provided.	• Opportunity for labour intensive alternative business development on Lihir during the life of mine. • People intensive development would result in changed customary lifestyles.

Standards of Living	• Significant impacts to individuals who make their living from the mine, either providing goods and services to the mine-site and camp or those being directly employed to work at the site. • Communities standard of living impacted as a result of loss of earnings. • People will leave Lihir to search for work, with some pressure reduced on food sources.	• Health, education and government services will be maintained due to Sustainable Community Development Plan. • As part of the SCDP agreements, Trusts will help provide support to the community after the mine has closed. • Refer to the population comments above.

Police and Court Facilities	• It is likely there will have been substantial progress in the development and implementation of the Law and Order Committee’s strategy. • Potential for some civil unrest upon final closure. • Impacts upon existing police resources	• Sustainable Community Development Plan support for long term government.

Table C.7.5 Stage 2 Closure (2040) Socio Economic Impacts and Issues cont’d


Area of Impact	Impacts and Issues	Comments
Emergency Facilities	• It is envisaged an agreement between LMC, the government and the local community will have been made in order to transfer the emergency services upon closure in 2040.	• At present almost all emergency services on Lihir are provided by LMC. Search and rescue operations, fire services and medical evacuations are provided at the company’s discretion without any charge.

Utilities	• It is expected that following closure, 50% of the remaining townsite infrastructure will be demolished and the sites rehabilitated subject to negotiation with the community and regulators. • Under the SCDP there are plans to develop the Londolovit township with a town authority to be established to manage and plan for the development. • Water supply and associated equipment will be left to provide water from Londolovit weir. • The 6MW power supply to Londolovit will be maintained and transferred for use to provide electricity to the local community.	• Sustainable Community Development Plan support for long term utility services.

Transport	• Following closure, the remaining light and heavy vehicles will be resold, salvaged or transferred to the community. • The airport will be handed over to the Government. • All roads will be repaired to design standards and handed over as-is to the community.	• Agreements to be made between LMC, local community and government for transfer of roads, airport and vehicles.

Environment	• A post monitoring and maintenance phase (Stage 3) will be initiated. • An extensive rehabilitation and revegetation programme will have been undertaken to include the following; • Return of the land to conditions capable of supporting prior land use; • Mitigation of significant adverse effects on the environment; • Use of waste rock for backfill and of topsoil for reclamation to the extent feasible; • Recontouring of slopes to minimise erosion and runoff; • Planting of native species of vegetation to prevent erosion and to encourage self- sustaining development of a productive ecosystem on the reclaimed land; and • Decrease in the Island’s population after 2040 will reduce pressures on land clearing for subsistence activities.	• LMC environmental remediation and rehabilitation programs during and following closure aimed at achieving end land use criteria.. • Exception will be the footprint of the main pit that will be flooded to provide a lake. • Details of LMC rehabilitation activities following closure is discussed in Part B of this report.

Employment	• All mine operations and associated activities cease resulting in the loss of employment for vast majority of staff and contractors. • Services provided by local contractors and businesses cease with minor exceptions such as ongoing community infrastructure maintenance. • Potential employment opportunities may exist to complete closure depending on social conditions. • All non Lihirian and expatriate employees will be repatriated to place of origin. • Vast majority of Lihirian employees would cease employment immediately with little opportunity to continue with meaningful work on Lihir. • Lihirian employees would almost all initially remain in their home villages. • Those with sufficient education, trade certification or work experience would gradually leave the island as they found jobs elsewhere in PNG.	• Largest impact on LMC workforce affected would be PNG and Lihirian staff — 90% of workforce are from PNG, 37% of workforce are Lihirians. • Refer to Table C.7.1 — LMC Employee categories • Repatriation of employees and payment of statutory redundancy entitlements to take effect.

Local Businesses	• Local landowner businesses that rely on direct LMC contracts for their livelihood cease to operate almost immediately. • Smaller local enterprises relying indirectly on the mining operations and the presence of a large population of wage earners, would gradually close. • Local companies are likely to lay off employees, many of whom are non- Lihirian. • Local companies that had diversified their activities, acquired assets or investments elsewhere in the country would have any ongoing income. • Businesses with loan exposures, would likely fail to meet repayments resulting in repossession of assets by banks. • Without any other major form of economic activity virtually all business activity on the island would stop. • Businesses that would survive would be those that serviced ongoing local demands — such as village trade stores, vehicles and small boat transport.	• Refer to Table C.7.4 for the types of services affected. • Potential opportunity for contract work and support services to complete closure.

Area of Impact	Impacts and Issues	Comments
Training and Education	Training • All in-house formal apprenticeship and competency-based staff training would cease. • Scholarships and sponsorships discontinued. • The Tutorme Women’s Training Centre would likely cease operation. Education • LMC financial support for education facilities and services cease. • Impact on the community schools and the high school would be principally felt due to the withdrawal of operational support costs. • Royalty payments and compensation cease and subsidies, transport services, utilities (power and water), school materials and supplies would be seriously affected. • Some ancillary staff made redundant. • Salaries of teaching staff are covered by the National Teaching Service, and are unlikely to be affected. • The High school’s boarding school functions may be closed, affecting some students from the outer islands.	• Sustainable Community Development Plan supporting education facilities and services would be phased out.

Health Services	• Major impact on health services for Lihir communities. • Improvements in health status of Lihirians and the high standard of buildings and equipment would mean that some of the gains made would not be lost. • The medical service contractor would be withdrawn, the health centre at Londolovit would have reduced staff and no qualified medical practitioner. • Given the Centre’s total dependence on mining related revenues for its staffing and operations, the service would struggle. • Palie Health Centre would continue to provide services and maintain core staff. • Community Health Workers servicing rural aid posts on Lihir and surrounding islands may lose their funding support from the local level government. • Visiting specialists and health campaigns (including TB treatment, HIV/AIDS/STD programs) would be reduced, dental services would reduce. • Much of the outreach work currently supported by LMC would cease and it is unlikely that vaccination rates would remain at the high level currently attained.	• Sustainable Community Development Plan supporting long term health facilities and services would be phased out. • Health services on Lihir are more vulnerable than education services to premature mine closure because of the dependence of some services on mining revenues for staffing and operational costs. • The Lihir Medical Centre is principally dependent on an annual LMC grant of around US$1.5 million (K6 million) to support its staff and operations. • Under the IBP agreement the national government allocates an annual administrative grant of K150,000 to support the salaries of selected staff. • The bulk of the salaries for core medical personnel such as doctors and nurses are paid by LMC.

Table C.7.6 Balance Date Closure (2004) Socio Economic Impacts and Issues cont’d


Area of Impact	Impacts and Issues	Comments
Population	• Population numbers will be reduced following repatriation of non-Lihirian employees and contractors. • Impacts on population size and location of Lihir community is likely to be minimal. • There is likely to be an exodus of Lihirians looking for opportunities elsewhere in PNG.	• Declining economic situation in PNG may mean that opportunities are low • People with qualifications and skills might find employment, but with Public Service cutbacks and without any new industrial/mining projects, many Lihirians will opt to stay where they have land rights and known amenities. • The closure of other PNG mine sites means that there are already many people with industry- specific skills elsewhere in PNG.

Standards of Living	• The Lihirian population will experience a dramatic decline in living standards due to reduced incomes. • As all forms of cash cropping have declined since the period of exploration, it would be some years before the pre-mining levels of copra and cocoa production were returned for example. • The advances in the living standards at a household level for the majority of Lihirians are dependent on wages earned directly or indirectly from the mine. • Few Lihirians could maintain their current living standard for longer than a few months.	• Sustainable Community Development Plan supporting Health, education and government services would be phased out.

Food Security	• Purchasing power would be affected although savings and termination entitlements ensure that people could continue to buy in the short term. • Supermarket sales would decline and may ultimately close soon after closure. • Boats could travel to New Ireland for supplies and small local trade stores would benefit in the short-term.	• Refer to LMC Socio-Economic surveys 2003. • Land pressures have placed limits on subsistence gardening. • The majority of Lihirians, including those who are employed, still have gardens and grow food for their families.

Police and Court Facilities	• Existing police services will be strained, but police withdrawal unlikely. • Long term services unlikely to be maintained at current level. • LMC assistance would cease, with ensuing negative effects on the efficiency and effectiveness of police operations on Lihir.	• Sustainable Community Development Plan support for long term government services would be phased out. • LMC assists police operations in a number of ways with transport, fuel and other material support. The company has also helped with the training and establishment of auxiliary and community policing.

Emergency Facilities	• Lihirians would lose LMC emergency services. • The ambulances at Palie and Londolovit would remain but budget provisions would not be adequate to maintain and replace vehicles in the long term. • Unless provision for a post-closure transfer of responsibility to LLG were arranged, Lihir would have no emergency fire service. • Emergency Medivacs are subsidised by LMC — not feasible after closure.	• At present almost all emergency services on Lihir are provided by LMC. • Search and rescue operations (especially relating to boats lost at sea), fire services and medical evacuations of people in the community are provided at the company’s discretion without any charge.

Utilities	• Government property such as power lines, satellite dishes, transmitters, pylons etc and the airport power supply would remain. • Power generation from the power stations would be significantly reduced. • Water supply and sanitation affected due to resource and maintenance requirements.	• Sustainable Community Development Plan support for long term utility services would be phased out. • Currently the water supply and sewerage to the township is operated by LMC.

Transport	Land • Decline in the use of motor vehicles as the cash economy declined. • Fuel imports by LMC would cease — supply costs would rise. • Contractors may maintain passenger vehicles and charge fares. • Short term, maintenance of vehicles would be possible (due to the training of mechanics) but in the long-term the number of vehicles would decline as people would not have the means for replacing them. Sea • Wharf facilities at the mine site and those at Londolovit would remain. • Maintenance of facilities would be minimal, due to reduced cash flows. • Majority of owners would be unable to derive income from their boats and therefore unable to maintain engines or buy fuel readily. Air • Air services significantly impacted as mining project personnel currently account for 98% of all passengers, and 90% of all freight is carried for LMC. • Currently LMC pay all maintenance costs for the airport. • It is more likely that in the long term services would be provided irregularly on an ‘on call’ basis, as is the case in several other places in PNG.	• Excess vehicles may be available for resale to the Lihirian community. • The majority of boats on Lihir are owned by Lihirians. Many are contracted by the company to transport employees from Malie, Masahet and Mahur. • Most air travel by Lihirians is currently paid for by LMC, government or businesses and involves only a handful of people. • The airport would not be maintained at current levels, and the airport facilities would deteriorate and be downgraded to perhaps a weekly or monthly basis.

Environment	• Orderly shutdown would be required including implementation of planned closure rehabilitation, decommissioning, monitoring and maintenance programs	• Part B of this Report details the environmental issues and impacts associated with balance date closure.

SOCIO ECONOMIC CLOSURE COST ESTIMATES

The socio economic issues and impacts of the various closure scenarios have been discussed in the preceding sections of this report. The planned closure of the operation will have serious implications for Lihirian communities and other stakeholders. A way of life for generations of Lihirians and other PNG nationals would profoundly change. However, the SCDP and other planning initiatives are designed to provide for compensatory mechanisms to replace many of the mine related benefit streams leading to financial independence and self reliance leading up to and post mine closure.

The indirect financial costs and liabilities associated with closure involving loss of contractor services, government revenue streams, LGL benefit streams and employment income are outside the scope of this report. Nonetheless, the scale of the impact can be deduced from information provided in the previous sections of the report. This section will provide liability estimations for each closure scenario in terms of employee redundancy, severance and repatriation costs for the LGL workforce as shown in Table C.8.1.

PART D SUMMARY

D.1		SUMMARY AND CONCLUSIONS

		This update to the 1999 Mine Closure Plan has been written based on site and regulatory conditions to calendar year end 2004. There have been significant changes in the mine operations compared to those envisioned when the first closure plan was prepared in 1999. These changes, and where possible likely future developments in the mine’s operating conditions, have been taken into account in developing the closure strategies outlined in this report.

		An improved understanding of the environmental and bio-physical setting of the Mine has been obtained since 1999, from ongoing studies for the closure plan and other related work. Currently a major initiative is underway, as part of an updated Environmental Impact Assessment, to further understand the impacts of the Mine and data from this work will be relevant in future closure plan updates.

		LMC consider that community involvement and community support throughout the mine life is integral to orderly mine closure. Hence this report contains a detailed description of current programs and planned programs aimed at helping the community achieve a sustainable destiny.

		A comprehensive and detailed estimate of costs, both for planned closure and for unscheduled ‘balance date’ closure has been prepared in a format suitable for periodic updates. The cost for both planned and balance date closures have increased since the 1999 estimate, due to a combination of expanded mine operations and an improved understanding of the closure scope.

		Major risks have been identified related to closure although much work needs to be done on detailed risk assessment and preparation of risk management plans, see Section D.2 below.

		Closure planning is a progressive activity and this closure plan assumes that the commitment to incremental rehabilitation will be maintained. As noted in Section D.3, the closure plan will be updated annually for the balance date closure and this

D.2		ACTION ITEMS

D.2.1		Risk Assessment and Management

		Section A.6 (Risk Management) summarises the potential impacts associated with the bio-physical and socio-economic aspects of the project. The proposed management strategies associated with each of the identified potential impacts are detailed within Parts B and C of the report. To further these strategies, detailed risk assessments and risk management plans will be undertaken for each of the significant potential impacts where information is presently insufficient or unavailable.

		The risk assessment process will define a series of action items for advancing the closure planning.

D.2.2		Current and On-going Studies

		Drainage and Sediment Control

		Studies into drainage and sediment control continue as part of the implementation of the MWSAMP, primarily to reduce the intensity and extent of surface turbid plumes that are generated within Luise Harbour. Work in progress includes separation of contact and non-contact water via diversions, improvements to the sediment trap(s) and augmentation of mill water supply from caldera creeks. Long term integrity of water management and diversion structures will form part of final closure.

		Bathymetric Studies

		Bathymetric studies are underway for both the Deep Sea Outfall project (DSO2) and the existing Deep Sea Tailings Placement (DSTP) system. Investigations include a comprehensive oceanographic profiling study and sampling program to support the establishment of a representative physical oceanographic database. These data will also provide input to the engineering design of the pipeline and outfall. Data from these studies will be needed to confirm closure assumptions related to the outfalls and tailing placement.

Page 113


Lihir Management Company Limited Lihir Gold Mine — Mine Closure Plan Update 2004		December 31, 2004

		Waste Rock Disposal

		Regular quarterly surveys of the submerged waste rock pile, are currently being taken as part of the existing EMMP. The survey data needs to be assessed to determine if the current dumping location is meeting the requirement for a minimum 100 m of ocean water column above the rock dump. Potential impacts to the near shore sedimentation rates and coral reefs will also need to be assessed. The closure plan may need to be adjusted if the offshore rock dump does not meet the water depth criteria at end of pit life and if long term impacts are identified.

		Biological Studies

		Studies are being continued to identify short and long term impacts of the Mine on local and regional flora and fauna (terrestrial and marine).

		Other Studies

		In parallel with studies related to closure, many other programs are in place aimed at improving operations. These programs collect data that is relevant to closure.

D.2.3		Further Studies

D.2.3.1		General

		The following is a list of studies proposed to improve closure planning. This is not a complete list and other items will emerge from the risk assessment/risk management planning process.

D.2.3.2		Acid Rock Drainage Studies and Control Strategy

		Management of ARD from the low-grade ore stockpile footprints, harbour platform and open pit has been identified as a significant closure issue. A preliminary assessment of ore and waste rock geochemistry was undertaken as part of the Environmental Plan technical studies (NSR, 1988). However, to fully characterise the ARD potential and determine closure implications, additional studies will be undertaken.

Page 114


Lihir Management Company Limited Lihir Gold Mine — Mine Closure Plan Update 2004		December 31, 2004

D.2.3.3		Final Void Study

		A final void study is proposed to determine the most appropriate and feasible long-term options for pit closure. The study may have significant implications for the pit design and therefore is regarded as a matter of priority. The study will include investigations into pit wall stability, predicted pit water quality including ARD generated from the pit walls, groundwater inputs (particularly geothermal groundwater), freshwater and seawater inputs and engineering designs including the mechanisms of exchange between pit and ocean waters.

D.2.3.4		Contaminated Land Studies

		A register will be prepared of areas of hydrocarbon and metal contamination resulting from operational activities. This work, and a parallel monitoring program, will provide information for rehabilitation and cleanup programs. Where possible improvements will be proposed to operations to reduce closure work.

D.2.3.5		Human Health Studies

		Although operational issues related to human health do not necessarily directly impact physical closure, health is an important factor in community issues which are so critical to orderly closure. Therefore, studies to identify the direct and indirect impacts on local and regional human health resulting from the mine sites activities will be continued. This work will include health and safety issues at the site and any indirect impacts from mine site activities.

D.2.3.6		Government Liaison

		Regular discussions with the Government on the progress of rehabilitation and closure planning will continue. LMC will seek advice and clarification where necessary, and provide input where appropriate into policy development. For the latter in particular, the PNG Department of Mining’s (DOM) Green Paper on Sustainable Development Policy and Sustainability Planning Framework for the Mining Sector in PNG will be an essential element of continued discussions between LMC and the Government. It is the aim of LMC’s ongoing closure planning liaison

Page 115


Lihir Management Company Limited Lihir Gold Mine — Mine Closure Plan Update 2004		December 31, 2004

		process to ensure that mine closure planning is conducted in the full knowledge of, and with full approval of, the PNG Government.

D.2.3.7		Community Consultation

		LMC recognise that consultation with all stakeholders but specifically Lihirians needs to become an integral part of the closure planning process. LMC will continue consultations and discussions with the Lihirian community to establish the preferred closure options. As part of on-going consultation, the Lihirians in particular will be asked to determine which mine facilities are potentially of the most use to them, and the preferred end use for all rehabilitated land.

D.2.3.8		Social progress

		As part of the Socio-Economic Development Plan support for long term health, education and government services facilities and services, LMC will identify further socio-economic studies where applicable.

D.2.3.9		Business Development

		Further socio-economic studies and discussions with the community will enable LMC to identify the potential for alternative business opportunities to be created during the life of mine which may provide ongoing employment and incomes on Lihir.

Lihir Management Company (LMC) recognizes excellence in environmental management and an open partnership with the community are essential to the success of the Lihir Gold Mine, and the long-term development of the community. Lihir Gold therefore has a commitment to sound environmental management in consultation with its neighbouring communities. This is reflected through the Company’s Community and Environmental Policy (Appendix 1). Fundamental to the policy is the Company environmental vision as described in the policy.

ii) LMC Environmental Plan (1992)

As part of the legislative process for new mineral developments, LMC produced an Environmental Plan in 1992 for the Lihir Gold Mine. The Environmental Plan includes the following:

	•		A description of the project and its viability;

	•		The proposed development and associated activities and operations;

	•		The development timetable;

	•		The existing social, physical and biological environment;

	•		The environmental impacts and safeguards;

	•		The principles and objectives for environmental management and monitoring; and

	•		The proposed strategy for mine rehabilitation and abandonment.

The plan was formally submitted to the Government and following an assessment period received formal government approval.

iii) LMC Environmental Management and Monitoring Program (EMMP)

The Lihir Environmental Management and Monitoring Program (EMMP) details:

	•		LMC’s monitoring and reporting commitments to the PNG Department of Environment and Conservation (DEC), Department of Mining (DoM) and community representatives;

	•		LMC’s monitoring requirements which arose from the identification of key environmental issues documented in the Lihir Project Environmental Plan (EP);

	•		The specific monitoring elements, and the rationale behind these monitoring programs. This includes the statutory monitoring associated with the Water Use Permits held by LMC and the routine environmental monitoring and reporting programmes.

The EMMP has two main objectives:

	•		Implementation of LMC’s environmental management policies and procedures; and

	•		To detail monitoring of the mine’s environmental impacts and LMC’s compliance with PNG regulatory permits and licences.

The procedures relating to the EMMP such as the collection of data and samples, analysis, quality control and reporting are integrated into the Company Environmental Management System (EMS) prepared in accordance with (and externally audited against) the ISO14001 international standards for environmental management.

Results from the EMMP are reported to LMC management, PNG Government and the Lihirian community and LMC use the information to minimise the environmental effects of the mine so the operation continues to meet its environmental objectives and the mine is in compliance with relevant environmental standards. The data collection and reporting schedule for EMMP Elements is listed in Appendix III. The EMMP is updated and revised every four years, takes into account the results of monitoring data, surveys, investigations and external and internal audit findings. It is currently being revised for reissue.

iv) LMC Sustainable Development Community Plan (SDCP) (Formally, The Integrated Benefits Package)

The Integrated Benefits Package (IBP) is a document which seeks to incorporate all of the commitments and benefits that the people of Lihir were promised in return for their agreement the project proceed. As well as the agreement between the community and the company, it also contains the agreements reached between the people of Lihir and the national, provincial and local level governments.

The IBP was signed in April, 1995 and marked the formal agreement of the people of Lihir to the start of the Lihir Gold project. The original IBP was formulated over a period of almost five years (from 1990) and was the result of many hours of negotiations and discussions between LMC, the Lihir Mining Area Landowners Association Inc. (LMALA), representing the landowners, and the Nimamar Development Authority (NDA), representing the people of Lihir.

A review of the IBP was initiated in 2001 and is currently in the latter stages of production being renamed the SDCP in line with the terminology favoured by the PNG Government (See Department of Mining Green Paper (2003) on mine closure). This followed the appointment of the Joint Negotiating Committee (JNC), by the Nimamar Rural Local Level Government (NRLLG), and the Lihir Mining Area Landowners Association (LMALA).

Although the original IBP will remain as a base document, following more than seven years experience and observations from the viewpoint of all the participants, the document has been updated to reflect changes at Lihir since the original IBP was issued. The implications of the SDCP for closure are discussed in more detail in Part 2 of the report.

v) Mining Development Contract

The Mining Development Contract (MDC) provides a mechanism for the transfer of ownership of LMC assets (works and facilities) to the State. The importance for closure planning is both liability and risk are extinguished as soon as title is vested in the State.

Page I-4


Lihir Management Company Limited Lihir Gold Mine — Mine Closure Plan Update 2004

Clause 5.1 of the MDC identifies “Works and Facilities” which are capable of being used by the State. However, the following three categories are excluded (Appendix B):

	•		Administrative and accommodation buildings for the company’s workforce;

	•		Installations and infrastructure directly used in the mining and processing of ore; and.

	•		Roads in the mining area.

In the 1999 MCP, the following loans and agreements were noted as expiring in 2003. It is understood these loans and agreements have now expired.

	•		Export Finance and Insurance Corporation Agreement

	•		Multilateral Investment Guarantee Agency

	•		Mining Industry Consultants Agreement

vi) Lease Requirements

a) Special Mining Leases and Mining Leases

The conditions for Special Mining Lease No. 6 and Mining Lease (ML) No.s 125 and 126 were reviewed and found to contain no conditions relevant to closure planning.

b) Lease for Mining Purposes and Mining Easements

The conditions for Lease for Mining Purposes No.s 34 and 35, and Mining Easements Nos. 71, 72 and 73 were reviewed. The conditions specify:

•

‘the Lessee shall do all things necessary to surrender the lease (or easement) or part of the lease (or easement) to the State.’

We believe the requirement is intended to apply to the transfer of title and has no specific implications for closure.

Page I-5


Lihir Management Company Limited Lihir Gold Mine — Mine Closure Plan Update 2004

vii) Rio Tinto Requirements

a) Rio Tinto Statement of Business Practice

Rio Tinto’s statement of business practice ‘The way we work’ (Rio Tinto 2003) includes reference to closure planning. Specifically in relation to the Environment and states;

“Wherever possible we prevent, or otherwise minimise, mitigate and remediate, harmful effects of the Group’s operations on the environment. We develop standards and build systems to identify, assess and manage environmental risk. These apply at each stage of exploration, development, operation and closure, as well as in acquisition and divestment evaluations”.

In the Health, Safety and the Environment (HSE) policy, there is the requirement for all subsidiaries to provide for HSE related operating, reclamation and closure costs in preparing investment proposals, annual plans and accounts. Moreover the policy also requires subsidiaries to prepare and maintain a plan for the eventual closure of each operation including: management of social and environmental impacts, estimates of closure costs and financial provisions, and consultation and cooperation with local communities. The Rio Tinto Communities policy requires continuing and effective communication with local communities.

Rio Tinto’s statement of business practice also states the Company subscribes to the following external charters and codes of practice:

	•		International Chamber of Commerce Business Charter for Sustainable Development;

	•		Environmental Charter of the International Council on Metals and the Environment; and

	•		Australian Minerals Industry Code for Environmental Management.

b) Rio Tinto Closure Planning Standard and Guidelines 2004

Rio Tinto has developed a closure planning standard and guideline which provides guidance for the closure planning process. The intent of the guide is to ensure

Page I-6


Lihir Management Company Limited Lihir Gold Mine — Mine Closure Plan Update 2004

operations undertake effective on-going planning and implementation for closure to minimise adverse impacts on the environment and make a positive contribution to community life in surrounding areas. This will be accomplished through:

	•		Early Planning and funding for closure;

	•		Progressive decommissioning and landscape rehabilitation;

	•		Consulting fully with stakeholders; and

	•		Integrating closure strategies with mine plans.

Other areas covered by the Rio Tinto Mine Closure guidelines are:

	•		Preparation of a closure study to identify legal requirements, landowner and community expectations, and impacts to be addressed;

	•		Development of a closure strategy to identify closure objectives, measures and options for meeting the objectives, and cost estimation;

	•		Development of socio-economic strategy including communications plans;

	•		Decommissioning (e.g. the act of closure); and

	•		Post closure management and monitoring.

The scope and format of this mine closure plan is consistent with the Rio Tinto closure planning guidelines.

viii) International Standards of Best Practice

The term ‘international standards’ implies high standards from elsewhere in the world or at least higher standards than would otherwise have been acceptable for a mining project in a developing country. Many of these requirements and standards cover similar issues and goals and a list of international standards that are relevant to the management of mine operations and the environmental and socio-economic aspects

Page I-7


Lihir Management Company Limited Lihir Gold Mine — Mine Closure Plan Update 2004

of mine closure are listed in Table A.3.2. The following section expands upon this list, with selected items discussed in detail.

World Bank Standards and Guidelines

There a number of environmental guidelines that the World Bank and IFC produce for its projects and each of these are expanded upon below:

	•		The World Bank Pollution Prevention and Abatement Handbook (PPAH) (1998).

	•		World Bank Environmental Assessment Sourcebook (1991, as amended).

	•		The IFC environmental, health and safety guidelines (1991-1993).

	•		The IFC Safeguard Policies and IFC procedures (1986-1998).

	•		World Bank Equator Principles (2003).

World Bank Pollution Prevention and Abatement Handbook (PPAH)

The PPAH was issued in 1998, designed to be used in context of the World Bank Group’s safeguard policies, as set out in Operational Policy (OP) 4.01, “Environmental Assessment” (1998), and related documents eg. IFC Procedure for Environmental and Social Review of Projects (1998). The Handbook promotes the concepts of sustainable development by focusing attention on the benefits, both environmental and economic of pollution prevention, including cleaner production and good management techniques. This handbook is divided into three parts:

	•		Part 1 — Summary of key policy lessons in pollution management;

	•		Part 2 — Presents good practice notes on implementation of policy objectives, based on experience with World Bank Group Projects and lessons learned from policies and practices from other agencies and organizations in this field;

	•		Part 3 — Provides detailed guidelines to be applied in the preparation of World Bank Projects. The guidelines, cover almost 40 industrial sectors and include current thinking on abatement and control, numerical targets for reducing pollution and maximum permissible emissions levels.

Page I-8


Lihir Management Company Limited Lihir Gold Mine — Mine Closure Plan Update 2004

PPAH guidelines applicable to LMC operations include PPAH 2 — Base Metal and Iron Ore Mining. Moreover, there are the following guidelines awaiting formal issue which include similar requirements for mine closure:

	•		Draft IFC Environment, Health and Safety Guidelines for Mining and Milling — Open Pit (1995).

	•		Draft IFC Environmental, Health and Safety Guidelines for Precious Minerals Mining (2004).

These guidelines require project sponsors to prepare and implement a mine closure and restoration plan. The plan should include the reclamation of tailings deposits, waste rock deposits, open pit areas, sedimentation basins, and abandoned mine, mill and camp sites. The following should be covered in the plan:

	•		Return of the land to conditions capable of supporting prior land use, equivalent uses or other acceptable uses;

	•		Elimination of significant adverse effects on adjacent water resources;

	•		Use of waste rock for backfill and of topsoil (or other acceptable materials) for reclamation to the extent feasible;

	•		Recontouring of slopes to minimise erosion and runoff;

	•		Planting of native species of vegetation to prevent erosion and to encourage self-sustaining development of a productive ecosystem on the reclaimed land;

	•		Post-closure acid rock drainage and tailings management, reduction of ARD formation by sealing off pyrite containing waste from oxidation and percolating water; and

	•		Budget and schedule for pre- and post-abandonment reclamation activities.

The guidelines also provide details on pollution prevention measures, emissions guidelines, treatment technologies, monitoring and reporting.

Page I-9


Lihir Management Company Limited Lihir Gold Mine — Mine Closure Plan Update 2004

The IFC Environmental, Health and Safety Guidelines

These were written in the early 1990s and for many industries and sectors, there are no parallel guidelines in the PPAH. It is envisaged new guidelines will be written to replace the series and included in the PPAH. The new guidelines will bring up to date the guidelines incorporating more recent developments in environmental management systems and cleaner technology. Although currently there no IFC guidelines specific to mine closure there are others which may in part be applicable to LMC operations including Geothermal Projects, Port and Harbour facilities and Hazardous Waste Management.

World Bank Equator Principles

In 2003, ten leading banks adopted voluntary guidelines for managing environmental and social issues surrounding project financing. The signatories agreed to a series of guidelines for assessing project finance deals, based on those used by the International Finance Corporation (IFC), the World Bank’s private finance arm and apply to projects globally across all industry sectors.

Since then, the number of banks which have adopted the Equator Principles has doubled with more expected to follow. As such, the group now accounts for around 80% of global project financing. The Principles are a global framework, for financial institutions to determine, assess and manage environmental and social risk, and best practice standards in project financing.

Moreover, the Principles only apply to projects with a total capital cost of $50 million or more. The Principles see the banks, classify projects into three groups, based on IFC policies. Borrowers developing projects in the two higher-risk groups (Category A and B) are required to carry out an Environmental Assessment (EA) covering issues such as socio-economic impacts, sustainable development, biodiversity, pollution prevention and waste minimization. Reference will have been made to the World Bank and IFC Pollution guidelines and safeguard policies.

For high risk projects, developers are required to prepare an Environmental Management Plan (EMP), drawing on the conclusions of the EA and demonstrating

Page I-10


Lihir Management Company Limited Lihir Gold Mine — Mine Closure Plan Update 2004

adequate stakeholder consultation. These Principles will be incorporated into loan covenants and, if borrowers fail to comply, they will be judged to be in default.

World Bank Environmental Assessment Sourcebook

The World Bank’s Environmental Assessment Sourcebook (World Bank, 1991 and amendments) includes a number of useful documents concerning mine closure and rehabilitation. Notably Chapter 10 of the Source book (Environmental Assessment of Energy and Industry Projects)(1999) includes a section on Mining and Mineral processing. Within the section the following is discussed:

	•		environmental and socio-cultural issues and impacts,

	•		management, training and monitoring,

	•		reclamation

Moreover a number of recent amendments and updates to the Source book refer to mine closure. Of note, Update 22 (1998) — Environmental Assessment of Mining Projects includes guidance for mine closure including:

	•		Environmental aspects and impacts

	•		Tailings treatment, management and disposal

	•		Decommissioning, rehabilitation and closure planning

ANZMEC and MCA Strategic Framework for Mine Closure

The Australia and New Zealand Minerals and Energy Council (ANZMEC)* and the Minerals Council of Australia (MCA) jointly developed a Strategic Framework for Mine Closure (ANZMEC and MCA 2000). The framework is designed to provide a broadly consistent approach to mine closure across the various Australian jurisdictions.

Page I-11


Lihir Management Company Limited Lihir Gold Mine — Mine Closure Plan Update 2004

The framework is structured around a set of objectives and principles grouped under six key areas:

	•		Stakeholder involvement;

	•		Planning;

	•		Financial provision;

	•		Implementation;

	•		Standards; and

	•		Relinquishment.

The Closure Plan draws upon the principles outlined in the ANZMEC and MCA strategic framework, as appropriate.

* The Ministerial Council on Mineral and Petroleum Resources (MCMPR) — formerly The Australia and New Zealand Minerals and Energy Council (ANZMEC).

Minerals Industry Code for Environmental Management (2000)

The Minerals Industry Code for Environmental Management produced by the Minerals Council of Australia (MCA) was originally produced in 1996 and following review in 1999 was reissued in 2000. It commits signatories to the following values:

	•		Integration of environmental, social and economic considerations into decision-making and management, consistent with the objective of sustainable development;

	•		Openness transparency and improved accountability through public environmental reporting and community engagement;

	•		Compliance with all statutory requirements, as a minimum; and

	•		A continually-improving standard of environmental performance and, through leadership, the pursuit of excellence throughout the minerals industry.

Page I-12


Lihir Management Company Limited Lihir Gold Mine — Mine Closure Plan Update 2004

The code has seven guiding principles, two of which include explicit statements on mine closure:

Principle 3: Integrating Environmental Management into the Way We Work

Ensuring environmental management and related social issues are high priorities by:

•

Ensuring resources are adequate to implement the environmental plans during operations and closure.

Principle 4: Minimising the Environmental Impacts of Our Activities

Responsibly managing immediate and longer-term impacts by:

•

Planning for closure in the design phases of a project and regularly reviewing to accommodate changes in site conditions, technology and community expectations

Rio Tinto is a signatory Company to the Minerals Industry Code for Environmental Management.

Environment Australia — Best Practice Environmental Management in Mining

The booklets provide best practice information for a range of mine issues that include a number relevant to mine closure;

	•		Mine Planning for Environmental Protection

	•		Community consultation and involvement

	•		Land form design for rehabilitation

	•		Tailings Containment

	•		Rehabilitation and Revegetation

	•		Environmental Risk Management

	•		Water Management

Page I-13


Lihir Management Company Limited Lihir Gold Mine — Mine Closure Plan Update 2004

The aim of the booklets are to help mine developers to identify the steps to be taken in order to conform to best practice behaviour, achieve good environmental performance, minimise conflicts with other land users, maintain ecological values in surrounding areas and restore or enhance the land use capability of the areas affected by their activities. They cover planning, monitoring, management systems and technical issues.

The information is also aimed at stakeholder representative groups, regulatory authorities, and students of mining and environment subjects to improve their understanding of environmental issues, improve environmental awareness, understanding of various principles and technologies, and the capacities of leading practitioners to significantly reduce the level of environmental impact from mining.

The booklets include illustrated case studies which demonstrate the application of a wide range of best practice techniques to address different environmental issues across many different mine type, commodity, geographic and environmental settings. The booklets offer references for further information and some contain short guides on the steps to be taken to achieve best practice on the specialised topic.

International Chamber of Commerce — The Business Charter for Sustainable Development — Principles for Environmental Management

In its 1987 report, “Our Common Future,” the World Commission on Environment and Development (Brundtland Commission) emphasised the importance of environmental protection to the pursuit of sustainable development.

To help business around the world improve its environmental performance, the International Chamber of Commerce created the Business Charter for Sustainable Development. It comprises sixteen Principles for environmental management and is aimed at assisting enterprises in fulfilling their commitment to environmental stewardship in a comprehensive fashion, in line with national and international guidelines and standards for environmental management.

Page I-14


Lihir Management Company Limited Lihir Gold Mine — Mine Closure Plan Update 2004

The aim of the Charter is for the widest range of enterprises to commit to improving their environmental performance in accordance with the Charter’s Principles, putting in place management practices to make environmental improvements, measuring and reporting this progress as appropriate internally and externally. It was formally launched in April 1991, is recognised as a complement to environmental management systems and is widely applied and recognised around the world.

Of note, the term environment in the Charter also refers to environmentally related aspects of health, safety and product stewardship.

International Council on Mining and Metals (ICMM) — Sustainable Development Framework

ICMM members offer strategic industry leadership towards achieving continuous improvements in sustainable development performance in the mining, minerals and metals industry. ICMM provides a common platform for the industry to share challenges and responsibilities as well as to engage with key constituencies on issues of common concern at the international level, based on science and principles of sustainable development.

One of ICMM’s key functions is driving improvements in the industry’s sustainable development performance. This is regarded as best being achieved by an integrated package of activities covering principles, and supported by public reporting, verification systems and the dissemination of good practice examples.

Rio Tinto is a member of the ICMM.

of mine closure are listed in Table A.3.2. The following section expands upon this list, with selected items discussed in detail.

World Bank Standards and Guidelines

There a number of environmental guidelines that the World Bank and IFC produce for its projects and each of these are expanded upon below:

	•		The World Bank Pollution Prevention and Abatement Handbook (PPAH) (1998).

	•		World Bank Environmental Assessment Sourcebook (1991, as amended).

	•		The IFC environmental, health and safety guidelines (1991-1993).

	•		The IFC Safeguard Policies and IFC procedures (1986-1998).

	•		World Bank Equator Principles (2003).

World Bank Pollution Prevention and Abatement Handbook (PPAH)

	•		Part 1 — Summary of key policy lessons in pollution management;

	•		Part 2 — Presents good practice notes on implementation of policy objectives, based on experience with World Bank Group Projects and lessons learned from policies and practices from other agencies and organizations in this field;

	•		Part 3 — Provides detailed guidelines to be applied in the preparation of World Bank Projects. The guidelines, cover almost 40 industrial sectors and include current thinking on abatement and control, numerical targets for reducing pollution and maximum permissible emissions levels.

Lihir Gold Mine — Mine Closure Plan Update 2004

	•		Draft IFC Environment, Health and Safety Guidelines for Mining and Milling — Open Pit (1995).

	•		Draft IFC Environmental, Health and Safety Guidelines for Precious Minerals Mining (2004).

	•		Return of the land to conditions capable of supporting prior land use, equivalent uses or other acceptable uses;

	•		Elimination of significant adverse effects on adjacent water resources;

	•		Use of waste rock for backfill and of topsoil (or other acceptable materials) for reclamation to the extent feasible;

	•		Recontouring of slopes to minimise erosion and runoff;

	•		Planting of native species of vegetation to prevent erosion and to encourage self-sustaining development of a productive ecosystem on the reclaimed land;

	•		Post-closure acid rock drainage and tailings management, reduction of ARD formation by sealing off pyrite containing waste from oxidation and percolating water; and

	•		Budget and schedule for pre- and post-abandonment reclamation activities.

The guidelines also provide details on pollution prevention measures, emissions guidelines, treatment technologies, monitoring and reporting.

Lihir Management Company Limited
Lihir Gold Mine — Mine Closure Plan Update 2004

The framework is structured around a set of objectives and principles grouped under six key areas:

	•		Stakeholder involvement;

	•		Planning;

	•		Financial provision;

	•		Implementation;

	•		Standards; and

	•		Relinquishment.

The Closure Plan draws upon the principles outlined in the ANZMEC and MCA strategic framework, as appropriate.

* The Ministerial Council on Mineral and Petroleum Resources (MCMPR) — formerly The Australia and New Zealand Minerals and Energy Council (ANZMEC).

Minerals Industry Code for Environmental Management (2000)

	•		Integration of environmental, social and economic considerations into decision-making and management, consistent with the objective of sustainable development;

	•		Openness transparency and improved accountability through public environmental reporting and community engagement;

	•		Compliance with all statutory requirements, as a minimum; and

	•		A continually-improving standard of environmental performance and, through leadership, the pursuit of excellence throughout the minerals industry.

Page I-12

Lihir Gold Mine — Mine Closure Plan Update 2004

The code has seven guiding principles, two of which include explicit statements on mine closure:

Principle 3: Integrating Environmental Management into the Way We Work

Ensuring environmental management and related social issues are high priorities by:

•

Ensuring resources are adequate to implement the environmental plans during operations and closure.

Principle 4: Minimising the Environmental Impacts of Our Activities

Responsibly managing immediate and longer-term impacts by:

•

Planning for closure in the design phases of a project and regularly reviewing to accommodate changes in site conditions, technology and community expectations

Rio Tinto is a signatory Company to the Minerals Industry Code for Environmental Management.

General Notes for Table IV.1.* Series

NOTES

Applicable to all worksheets

METHODOLOGY

		These notes are applicable to all worksheets and are given here so as not to be repeated.

1		General Demolition

1.1		The scope of work includes all identified equipment and facilities to be removed to be generally demolished down to ground level, including all plinths and up stands. Concrete slabs and services below ground will remain.

1.2		The predominant method of material disposal from demolished buildings, facilities and equipment at the mine site is via direct placement / disposal into the mine pit base.

1.3		Material which poses a risk to health or the environment e.g. tyres, electrical transformers, fuels, chemicals, re-agents and similar hazardous materials including — but not limited to — asbestos, ceramic fibre, chlorofluorocarbons (CFC s), Polychlorobiphenyls (PCB s), radioactive materials or mercury — to be removed from the site and to be disposed of as directed by the Project Manager

1.4		Material agreed by LMC to be of value for re-use by the local indigenous population which can be viably retained will be stockpiled in defined locations for subsequent recovery by local residents.

1.5		External vendors removing selected items of salvageable material which have been sold to outside organisations who are to remove materials from site at their cost shall be treated as an outside contractor and shall complete all site and safety inductions and shall comply with all operating and safety procedures applicable to the site

1.6		Ground slabs may remain. All reinforcing bars and anchor bolts shall be cut or ground flush with top of slab level.

		Top of slab shall be deemed to be top of plinth in the case of large plinths, (i.e. where the plinth is actually the predominant upper surface level) with prevailing ground contours adjusted by filling and grading to suit such a surface level. It is assumed selected filing shall be stockpiled during mining operations

		All areas shall be left suitable for access by vehicles or personnel without the risk of punctures or trip hazards.

1.7		Where existing ground slabs within former building footprints fall to sumps or trench drains, such sump or trench drain inverts shall be holed or cracked to ensure water cannot collect and then backfilled and compacted with clean fill to prevailing existing surface contours.

1.8		The adjacent surrounding ground shall be locally graded away from slabs — to prevent ponding and to allow runoff to flow into existing stormwater ditches or drains around the demolition site.

1.9		All works shall comply with the Demolition Plan and Demolition Methodology Statement

General Notes for Table IV.2.* Series

NOTES

Applicable to all worksheets

METHODOLOGY


		These notes are applicable to all worksheets and are given here so as not to be repeated.

1		General Demolition

1.1		The scope of work includes all identified equipment and facilities to be removed to be generally demolished down to ground level, including all plinths and up stands. Concrete slabs and services below ground will remain.

1.2		The predominant method of material disposal from demolished buildings, facilities and equipment at the mine site is via direct placement / disposal into the mine pit base.

1.3		Material which poses a risk to health or the environment e.g. – tyres, electrical transformers, fuels, chemicals, re-agents and similar hazardous materials including – but not limited to — asbestos, ceramic fibre, chlorofluorocarbons (CFC’s), Polychlorobiphenyls (PCB’s), ‘radioactive materials or mercury – to be removed from the site and to be disposed of as directed by the Project Manager

1.4		Material agreed by LMC to be of value for re-use by the local indigenous population which can be viably retained will be stockpiled in defined locations for subsequent recovery by local residents.

1.5		External vendors removing selected items of salvageable material which have been sold to outside organisations who are to remove materials from site at their cost shall be treated as an outside contractor and shall complete all site and safety inductions and shall comply with all operating and safety proceedures applicable to the site

1.6		Ground slabs may remain. All reinforcing bars and anchor bolts shall be cut or ground flush with top of slab level.

		Top of slab shall be deemed to be top of plinth in the case of large plinths,(i.e. where the plinth is actually the predominant upper surface level) with prevailing ground contours adjusted by filling and grading to suit such a surface level. It is assumed selected filing shall be stockpiled during mining operations

		All areas shall be left suitable for access by vehicles or personnel without the risk of punctures or trip hazards.

1.7		Where existing ground slabs within former building footprints fall to sumps or trench drains, such sump or trench drain inverts shall be holed or cracked to ensure water cannot collect and then backfilled and compacted with clean fill to prevailing existing surface contours.

1.8		The adjacent surrounding ground shall be locally graded away from slabs to prevent ponding and to allow runoff to flow into existing stormwater ditches or drains around the demolition site.

1.9		All works shall comply with the Demolition Plan and Demolition Methodology Statement

2		Notes pertaining to Mine Demobilisation

2.1		It is assumed the low grade stockpiles viz. Kapit North, Kapit South and Harbour base will be relocated to Minifie Pit 31/12/2004

2.2		Allowance has been made for 25% of the Heavy Mining Equipment to remain in service until 2040 to load Low Grade ore.

2.3		It is assumed the Workshop will remain to service the equipment remaining in service until 2040

2.5		Based on information from Phil Welten, Mine Manager at time of writing, it is assumed the cost of opening a channel from the foreshore to Minifie will be undertaken as a part of mining operations and the gold bearing ore recovered from the cut will cover the cost of mining operations. The cost of opening a channel into Kapit pit will be a matter of opening a channel in the coffer dam and will present no problems and minor cost.

2.6		Base on item 2.5 it is assumed access from the low grade stockpile at Kapit village will be via a haul road around the western side of the open pits along a purpose left bench.

General Notes for Table IV.3.* Series


NOTES
Applicable to all worksheets
METHODOLOGY
		These notes are applicable to all worksheets and are given here so as not to be repeated.

1		General Demolition

1.1		The scope of work includes all identified equipment and facilities to be removed to be generally demolished down to ground level, including all plinths and up stands. Concrete slabs and services below ground will remain.

1.2		The predominant method of material disposal from demolished buildings, facilities and equipment at the mine site is via direct placement / disposal into the mine pit base.

1.3		Material which poses a risk to health or the environment — e.g. tyres, electrical transformers, fuels, chemicals, re-agents and similar hazardous materials including — but not limited to — asbestos, ceramic fibre, chlorofluorocarbons (CFC’s), Polychlorobiphenyls (PCB’s), ‘radioactive materials or mercury — to be removed from the site and to be disposed of as directed by the Project Manager

1.4		Material agreed by LMC to be of value for re-use by the local indigenous population which can be viably retained will be stockpiled in defined locations for subsequent recovery by local residents.

1.5		External vendors removing selected items of salvageable material which have been sold to outside organisations who are to remove materials from site at their cost shall be treated as an outside contractor and shall complete all site and safety inductions and shall comply with all operating and safety proceedures applicable to the site

1.6		Ground slabs may remain. All reinforcing bars and anchor bolts shall be cut or ground flush with top of slab level. for the purpose. with prevailing ground contours adjusted by filling and grading to suit such a surface level. It is assumed selected filing shall be stockpiled

		Top of slab shall be deemed to be top of plinth in the case of large plinths, (i.e. where the plinth is actually the predominant upper surface level) during mining operations

		All areas shall be left suitable for access by vehicles or personnel without the risk of punctures or trip hazards.

1.7		Where existing ground slabs within former building footprints fall to sumps or trench drains, such sump or trench drain inverts shall be holed or cracked to ensure water cannot collect and then backfilled and compacted with clean fill to prevailing existing surface contours.

1.8		The adjacent surrounding ground shall be locally graded away from slabs to prevent ponding and to allow runoff to flow into existing stormwater ditches or drains around the demolition site.

1.9		All works shall comply with the Demolition Plan and Demolition Methodology Statement

2		Notes pertaining to Town site demobilisation

2.1		It is assumed 50% of Town site residences shall remain and 50% will be demolished

2.2		Allowance has been made to demolish camp one at the end of the mining phase in 2022

2.3		Refer to the Methodology statement in Townsite demolition for particular assumptions.

		It is assumed as normal in the mining industry, that work will be initially carried out by LMC staff with some hire of local equipment and contractors/consultants as required. As closure proceeds, more contractors will be used and LMC staff involvement will reduce.

B.6.4		Balance Date Closure Estimate Assumption and Schedule

		The basic schedule for planned closure is shown on Figure A.1.3. Balance date closure was assumed to require similar activity durations as those indicated on Figure A.1.3 to develop the approximate schedule shown on Figure A.5.1. Thus capital works estimates made for scheduled closure, are closely applicable to the Balance Date Closure case.

B.7		SUMMARY OF ESTIMATE COSTS FOR PLANNED AND BALANCE DATE CLOSURE

		A summary of the estimated costs for the options considered are presented in Table B.7.1. Details of the various items are presented in Appendix IV for the Planned Closure scenarios and Balance Date Closure conditions, and in the 1999 CMCP for the 1999 case.

		future. To do so will require considerable leadership and planning but the opportunity exists.

		Part C of this closure plan assesses the likely impacts and costs of the various closure scenarios in terms of the following:

	•		the welfare of the Lihirian population;

	•		government infrastructure and services; and

	•		business and employment.

	•		Government (national, provincial, local)

	•		Special Mining Lease (SML) landowners (Lihir Management Area Landowners Association — LMALA)

	•		Non-SML landowners (other Lihirians)

	•		Civil Society Groups (women’s, youth and church groups)

	•		Mining and Non-Mining Businesses

	•		Mine Employees

		provides an opportunity to regularly capture changes which impact mine closure. More comprehensive five yearly updates will occur for the planned closure.

		Although closure is a progressive process, the Mine closure is scheduled to occur in two main stages as follows:

	•		Closure of pit operations in 2022; and

	•		Closure of milling and remaining operations in 2040.

		This time frame allows for continuous improvements to closure planning which will be reflected in the annual and five yearly closure plan updates.

		A number of action items, including on-going studies and further studies are identified in the following subsections, as a framework for assisting in closure plan updates.

D.3		CLOSURE PLAN REVIEW PROCESS

		The closure plan will undergo regular review throughout the project life. LMC propose to formally update the Mine Closure Plan (MCP) every five years, although the balance date closure plan will be updated on an annual basis. Moreover, LMC propose to conduct an annual review of the MCP with the annual review conducted as part of the site’s Environmental Management System. The review will involve key personnel associated with all aspects of mine closure and the results of the review will be formally documented. Further updates of the mine closure plan will take into account results of the formal annual reviews.
