             REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Participants and Administrator of
the Kennecott Corporation Savings Plan for Hourly Employees

In our opinion, the accompanying statements of assets available for benefits and
the related statements of changes in assets available for benefits present
fairly, in all material respects, the assets available for benefits of the
Kennecott Corporation Savings Plan for Hourly Employees (the "Plan") at December
31, 2003 and 2002, and the changes in assets available for benefits for the
years then ended in conformity with accounting principles generally accepted in
the United States of America. These financial statements are the responsibility
of the Plan's management; our responsibility is to express an opinion on these
financial statements based on our audits. We conducted our audits of these
statements in accordance with the standards of the Public Company Accounting
Oversight Board (United States). Those standards require that we plan and
perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements, assessing the accounting principles used and significant estimates
made by management, and evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

Our audits were conducted for the purpose of forming an opinion on the basic
financial statements taken as a whole. The supplemental schedule of Assets Held
for Investment Purposes at December 31, 2003 is presented for the purpose of
additional analysis and is not a required part of the basic financial statements
but is supplementary information required by the Department of Labor's Rules and
Regulations for Reporting and Disclosure under the Employee Retirement Income
Security Act of 1974. This supplemental schedule is the responsibility of the
Plan's management. The supplemental schedule has been subjected to the auditing
procedures applied in the audit of the 2003 basic financial statements and, in
our opinion, is fairly stated in all material respects in relation to the basic
financial statements taken as a whole.

             KENNECOTT CORPORATION SAVINGS PLAN FOR HOURLY EMPLOYEES
                          NOTES TO FINANCIAL STATEMENTS

1.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     The  financial  statements of the  Kennecott  Corporation  Savings Plan for
     Hourly  Employees  (the Plan) have been  prepared on the  accrual  basis of
     accounting.

     The Plan  presents in the  statements  of changes in assets  available  for
     benefits  the net  appreciation  (depreciation)  in the  fair  value of its
     investments   which  consists  of  the  realized  gains  (losses)  and  the
     unrealized appreciation (depreciation) on those investments.

     Use of Estimates - The  preparation of the Plan's  financial  statements in
     conformity  with  accounting  principles  generally  accepted in the United
     States of America  requires the Plan  Administrator  to make  estimates and
     assumptions  that  affect  the  reported  amounts of assets  available  for
     benefits  at the date of the  financial  statements,  the changes in assets
     available for benefits  during the reporting  period and, when  applicable,
     the  disclosures  of contingent  assets and  liabilities at the date of the
     financial statements. Actual results could differ from those estimates.

     Risks and Uncertainties - The Plan provides for various investment options,
     in any  combination  of stocks,  bonds,  mutual funds and other  investment
     securities as designated by the employee. Investment securities are exposed
     to various risks, such as interest rate and market  fluctuations and credit
     risk.  Due  to  the  level  of  risk  associated  with  certain  investment
     securities, changes in the values of investment securities may occur in the
     near term.  Such changes  could  materially  affect  participants'  account
     balances and the amounts reported in the statements of assets available for
     benefits.

     Payments of Benefits - Benefits are recorded when paid.

     Investment  Valuation and Income  Recognition - The Plan's  investments are
     stated at fair value except for its insurance  contracts,  which are valued
     at  contract  value  (Note  3).  Quoted  market  prices  are  used to value
     investments.  Shares of mutual  funds are valued at the net asset  value of
     shares held by the Plan at year end.  Participant loans are valued at their
     outstanding balances, which approximate fair value.

     Purchases  and sales of  securities  are  recorded on a  trade-date  basis.
     Dividends are recorded on the ex-dividend date.


2.   DESCRIPTION OF THE PLAN

     The  following  brief  description  of the  Plan is  provided  for  general
     information  purposes only.  Participants  should refer to the summary Plan
     description, "Savings Plan for Hourly Employees," which provides a detailed
     discussion of the Plan, benefits and vesting of participants.

                          NOTES TO FINANCIAL STATEMENTS

2.   DESCRIPTION OF THE PLAN, (continued)

     General - The Plan is a defined contribution plan covering eligible,  union
     represented  hourly  employees of  Kennecott  Utah Copper  Corporation  and
     Participating Companies (collectively the Company), as defined in the Plan.
     Kennecott Utah Copper Corporation is an indirect wholly-owned subsidiary of
     Rio Tinto America Inc., which is an indirect wholly-owned subsidiary of Rio
     Tinto plc.

     Rio Tinto plc and Rio Tinto  Limited  entered into a dual listed  companies
     merger  in 1995  with the  effect  that the two  companies  operate  as one
     business  organization.  All eligible union  represented  hourly  full-time
     employees  of the Company can  participate  in the Plan  immediately  after
     completing three months of continuous service.

     Contributions  - An eligible  participant  may make a contribution of 1% to
     19% of his/her salary on a before-tax  basis via payroll  deduction up to a
     maximum  of  $12,000  for 2003 and  $11,000  for  2002.  Contributions  are
     allocated  among 17  investments,  as  designated by the  participant.  The
     Company matches employee  contributions  $0.50 for every dollar contributed
     by the  participant,  up to 6% of base wages. The Company match is invested
     in the same manner as the employee's contributions.

     Participant  Accounts - Each  participant's  investment account is credited
     with the  participant's  contributions  and an  allocation of the Company's
     contributions  and Plan  earnings  and is  charged  with an  allocation  of
     investment  management fees.  Allocations are based on participant earnings
     or account balances.  The benefit to which a participant is entitled is the
     benefit that can be provided from the participant's vested account.

     Each  participant may cause some or all of his or her current or cumulative
     contributions,  including any amounts  contributed  by the Company as match
     contributions,  to be  invested  in one or  more  of the  investments  made
     available through the Plan.

     Vesting  -  Participants   are   immediately   vested  in  their  voluntary
     contributions  plus  actual  earnings  thereon.   Vesting  in  the  Company
     contribution  portion of their  account plus  earnings  thereon is based on
     years of service. As of January 1, 2002, a participant is 100% cliff vested
     after three years of credited  service.  In the event of death or permanent
     disability, a participant becomes fully vested in the Company contributions
     and earnings thereon.

     Payment of Benefits - On termination of service, a participant may elect to
     receive an amount equal to the value of the  participant's  vested interest
     in his or her account in a lump-sum amount.

                          NOTES TO FINANCIAL STATEMENTS

2.   DESCRIPTION OF THE PLAN, (continued)

     Account  Forfeitures  -  Forfeited  non-vested  amounts  are used to reduce
     Company  contributions.  Forfeitures  from the Plan were $20,631 and $9,018
     for the  years  ending  December  31,  2003 and  2002,  respectively.  On a
     periodic basis, the Plan Administrator directs that accumulated, multi-year
     forfeitures be used to offset  employer  contributions.  The last time this
     occurred was for the year ended December 31, 2003 in the amount of $52,266.
     There was no such offset  directed for the year ended December 31, 2002. As
     of December 31, 2003, the Plan had $41,944 of unused,  forfeited non-vested
     amounts.

     Administrative - The Administrative Committee,  consisting of three or more
     persons  appointed  by the Board of  Directors  of  Kennecott  Utah  Copper
     Corporation,  administers  the Plan. The  Administrative  Committee has the
     sole power and  responsibility  to interpret and construe the provisions of
     the  Plan and  decide  on any  disputes,  and in  general,  to  direct  the
     administration of the Plan.

     Expenses - Putnam  manages  all  investments  except for the Plan's  Dwight
     Stable Value Fund.  The Company pays all other costs and expenses  incurred
     in  administering  the Plan. A third party  investment  manager manages the
     Plan's  Dwight  Stable  Value  Fund.  The  investment  manager  receives an
     investment  management  fee at an annual rate of 0.9% of the Dwight  Stable
     Value Fund's fair value  calculated  based on the Fund's average  month-end
     balance  for each  calendar  quarter  and paid  quarterly.  The  investment
     management  fees totaling  $15,967 and $13,986 for the years ended December
     31, 2003 and 2002,  respectively,  were paid by  participants of the Dwight
     Stable Value Fund.  Transaction  costs associated with the purchase or sale
     of Rio Tinto plc ADRs are paid by the participant.

     Plan  Termination  - The  terms  of the Plan may be  amended,  modified  or
     discontinued  after the effective date of the Savings Plan Agreement.  Such
     amendment,   modification   or   discontinuance   may  occur   pursuant  to
     negotiations  for employees at Kennecott  Utah Copper  Corporation  who are
     represented by the labor  organizations that are jointly referred to as the
     Union, or as required by law or to gain Internal Revenue Service  approval.
     No change, however, shall make it possible for any part of the funds of the
     Plan to be used for or diverted to  purposes  other than for the  exclusive
     benefit of  participants  or their  beneficiaries.  In addition,  no change
     shall  adversely  affect  the  rights of any  participant  with  respect to
     contributions made prior to the date of the change.

     If the Plan is  terminated in  accordance  with the terms  described in the
     preceding paragraph,  each participant's  account shall become fully vested
     and  nonforfeitable  and  distribution  of  Plan  assets  shall  be made as
     directed by the Administrative Committee.

            KENNECOTT CORPORATION SAVINGS PLAN FOR HOURLY EMPLOYEES
                          NOTES TO FINANCIAL STATEMENTS

3.   INCOME TAX STATUS

     The Plan obtained its latest  determination  letter on December 9, 2002, in
     which the Internal  Revenue Service stated that the Plan, as then designed,
     was in compliance with the applicable  requirements of the Internal Revenue
     Code. The Plan has been amended since receiving the  determination  letter.
     However, the Plan Administrator and the Plan's tax counsel believe that the
     Plan is  currently  designed  and being  operated  in  compliance  with the
     applicable  requirements  of  the  Internal  Revenue  Code.  Therefore,  no
     provision  for  income  taxes has been  included  in the  Plan's  financial
     statements.


4.   PARTIES-IN-INTEREST TRANSACTIONS

     Certain  Plan  investments  are  managed  by  Putnam  Investments.   Putnam
     Investments  is the  trustee  as  defined  by the  Plan,  therefore,  these
     transactions qualify as party-in-interest transactions.

     Transactions   associated   with  Rio   Tinto   plc  ADRs  are   considered
     party-in-interest  transactions  since Rio  Tinto plc is the  parent of the
     Company.


5.   INVESTMENTS

     Investments in common collective trust funds are stated at fair value based
     upon the  market  value of the  underlying  securities,  as  determined  or
     provided by the Trustee.  Collective  trust funds represent  investments in
     pooled funds.  Investments  are purchased and sold at the fair value of the
     underlying securities and receive the interest and dividend earnings of the
     underlying securities.

     Shares of mutual  funds are valued at the net asset value of shares held by
     the Plan at year end.

     Investments in common stock are stated at fair value based on quoted market
     prices.

     The Plan invests in both group annuity  contracts and synthetic  investment
     contracts.  The Plan has entered  into  investment  contracts  with various
     insurance  companies.  The Plan  maintains  the  contributions  in a pooled
     account.   The  account  is  credited  with  earnings  on  the   underlying
     investments and charged for Plan  withdrawals and  administrative  expenses
     charged. The contracts are included in the financial statements at contract
     value,  (which  represents  contributions  made  under the  contract,  plus
     earnings, less withdrawals and administrative expenses) because it is fully
     benefit  responsive.  For example,  participants may ordinarily  direct the
     withdrawal or transfer of all or a portion of their  investment at contract
     value.  There are no reserves against contract value for credit risk of the
     contract issuer or otherwise.

                          NOTES TO FINANCIAL STATEMENTS

5.   INVESTMENTS, (continued)

     The  guaranteed  insurance  contracts held by the Plan are accounted for at
     their  contract  value   (representing   invested  principal  plus  accrued
     interest)  as  reported  by  the  contract  issuers.  Synthetic  investment
     contracts  have   crediting   rates  that  reset   quarterly   based  on  a
     pre-determined crediting rate formula. This formula factors in the contract
     value,  the market value,  the yield to maturity and the  underlying  fixed
     income  investments.  In all cases,  the contract  value is  determined  by
     increasing the principal  balance by accrued  interest that is based on the
     contract value crediting rate of each contract.

     Synthetic  investment  contracts  are  comprised  of  both  investment  and
     contractual components.  The investment component consists of securities or
     units of a commingled pooled fund of fixed-income  securities,  referred to
     as the underlying investments.  Underlying investments may include, but are
     not limited to:

          o    Units of collective investment trusts ("CITs"),  shares of mutual
               funds, or actively managed  accounts,  which may include CITs and
               mutual funds which provide for contract value  accounting as part
               of the CIT or  mutual  fund  structure.  Any CIT or  mutual  fund
               investment has a stated target  minimum  average credit rating of
               "AA".
          o    U.S. Treasuries and other securities backed by the full faith and
               credit of the U.S. Government.
          o    Securities  rated  "AAA" at time of  purchase  and issued by U.S.
               Government Sponsored Entities.
          o    Other   fixed   income   investments   such  as   mortgage-backed
               securities,  asset-backed  securities,   collateralized  mortgage
               obligations,  corporate debt obligations and structured notes, in
               each case rated "AAA" at the time of purchase.

     The underlying investments are "wrapped" by contracts issued by third-party
     financial  institutions.  These wrap contracts provide benefit  withdrawals
     and  investment  exchanges  at the full  contract  values of the  synthetic
     contracts (i.e. principal plus accrued interest) notwithstanding the actual
     market value of the  underlying  investments  (i.e.  fair value of security
     plus accrued  interest).  In this manner,  wrap  contracts  are designed to
     smooth out the impact of normal  market  fluctuations  associated  with the
     performance of the underlying investments.

     The difference  between the market value of the underlying  investments and
     the reported  value of the  synthetic  contract is  generally  the implicit
     value of the wrap contract. A positive value implies that the wrap contract
     issuer is  obligated to the Fund for the  indicated  amount in the event of
     benefit  withdrawals  and or  investment  exchanges  from the  contract.  A
     negative value for the wrap contract indicates that the market value of the
     underlying investment exceeds the contract value.

5.   INVESTMENTS, (continued)

     The crediting rate of a particular  synthetic  contract is reset on a fixed
     schedule  basis  and is thus  tied  to the  performance  of the  underlying
     investments.
