NOTE 1- DESCRIPTION OF BUSINESS AND SIGNIFICANT EVENTS:

The operating companies that comprise Minera Mexico, S.A. de C.V. ("MM") and
Subsidiaries (collectively, "the Company") are in the metallurgical mining
industry. They engage in the exploration, mining and processing of metallic and
nonmetallic minerals as well as the mining of coal and the refinement of copper,
gold and silver. The Company is a 98.91% owned indirect subsidiary of Grupo
Mexico, S.A. de C.V. ("GMEXICO") through its holding company Americas Mining
Corporation (AMC).

At General Ordinary Stockholders' Meeting held on May, 28, 2003, the stock-
holders agreed to merge Grupo Minero Mexico, S.A. de C.V. ("GMM") a wholly -
owned subsidiary into MM. The merger became effective as from May 31, 2003, as
a result of which, the MM acquired all the assets, liabilities and capital of
the merged company, which ceased to exist as a legal entity. This operation
generated a Ps50,847 decrease in stockholders' equity.

NOTE 2  BASIS OF PRESENTATION:

the financial statements of GMM (a 98.91% owned subsidiary of Minera Mexico,
S.A. de C.V.) and those of its subsidiaries that consolidate the financial

The consolidated financial statements include the accounts of the Company and
its subsidiaries, all under the same management. All significant intercompany
balances and transactions have been eliminated in consolidation.

MM is not a corporation separate from the Grupo Mexico, S.A. de C.V. (GMEX).
It is, however, an entity establishment, registered pursuant to Mexican Law,
through which the Company holds assets, incurs liabilities and conducts ope-
rations in Mexico. MM comprises substantially all the assets and liabilities
of the Company associated with its mining operations in Mexico.



Foreign exchange - The Company's functional currency is the U.S. dollar. MM
maintains its books in Mexican pesos. Foreign currency assets and liabilities
are remeasured into U.S. dollars at current exchange rates except for inven-
tory, property plant and equipment and other assets which are remeasured at
historical exchange rates. Revenues and expenses are generally translated at
average exchange rates in effect during the period, except for those expenses
related to balance sheet amounts that are remeasured at historical exchange
rates. Gains and losses from foreign currency remeasurement are included in
net earnings.

b. Reclassifications -

Certain amounts in the financial statements as of and for the quarter ended
March 31, 2004 and 2003 have been reclassified in order to conform to the
presentation of the consolidated financial statements as of and for the quarter
ended March 31, 2004.

NOTE 3 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

a. Cash and cash equivalents -

Cash and temporary investments are primarily short-term investment fund, varia-
ble income securities and bank deposits with original maturities of three
months or less, and are valued at market.

b. Impairment of long-lived assets -

The Company, periodically reviews the recoverable value of its long-lived
tangible and intangible assets, including the goodwill, based on estimated
gross future cash flow from its cash-generating units. If the book value of
the assets exceeds the discounted value it recognizes impairment. The procedure
and criteria used by the Company are in line with the provisions of Statement
of Financial Accounting Standards (SFAS) No. 144 "Impairment of the Value of
Long-Lived Assets and their Disposal". Management of the Company considers that
as result of the study made at December 31, 2003 no impairment losses need to
be recognized.

c. Deferred charges -

- - Stripping costs- Stripping costs are costs associated with the removal of
waste materials after production has commenced. Over the life of the mine,
stripping costs are deferred in periods when the actual ratio of waste mate-
rials to mineral ore extracted is above the life-of-mine stripping ratio, which
represents the Company's estimate of the total amount of waste to be incurred
divided by the estimated total proven and probable reserves. In periods when
the actual mine stripping ratio is below the life-of-mine stripping ratio, the
Company reduces the net capitalized mine stripping asset proportionally with a
charge to amortization expense. In addition, deferred mine stripping costs are
amortized using the units of production method based on proven and probable ore
reserves. Copper resources contained in piles of leachable materials that have
been extracted from the mines are not included in the determination of units of
production amortization.

The Company's policy results in the smoothing of stripping costs over the life
of the mine and, in the view of the Company, better facilitates the matching of
mine production costs over the life of the mine with the mine's revenues.


- - Leaching material - Mexcananea capitalizes the cost of materials with low
copper content, extracted during the mining process ("leaching material"),
which are accumulated in areas known as leach dumps. The amortization of the
capitalized costs is determined based on the individual depletion of the leach
dumps, which is approximately from 5 to 8 years.

- - Mine development costs- Exploration costs incurred before operation of a site
begins are expensed as incurred, except for expenditures on specific properties
where proven and probable mineral resources have been confirmed, in which case
the expenditures are capitalized as mine development cost. Capitalized mine
development cost are amortized on a straight-line basis over the estimated use-
ful  lives of the corresponding proven metal reserves.

- - Other deferred expenses- Other deferred expenses comprise mainly licenses,
expenses related to the development of software for internal use, and debt
restructuring expenses, which are capitalized and amortized on a straight-line
basis over an average period between three and ten years, beginning in 1999 and
2000.

d. Investment in shares of associated and other unconsolidated companies-

Accounted for using the equity method on the based on the financial statements
of associated and other unconsolidated companies and restated on the same basis
as of the Company.

e. Goodwill -

 Beginning in 1998 the woodwill from the acquisition of Mexcananea is being
amortized over 10 years, the terms over which the benefits from this invest-
ment is expected to be realized.

f. Employee benefit obligations -

The Company records the liabilities from seniority premiums, pensions and reti-
rement payments similar to pensions as accrued, using actuarial calculations
based on the projected unit credit method and real interest rates. Accordin-
gly, the liability is being accrued which at present value will cover the obli-
gation for benefits projected to the estimated retirement date of the Company's
employees. Indemnity payments are charged to results in the period in which
they become payable.

Mexcananea provides medical and hospital services to all active employees and
retired unionized employees and the members of their families through a
subsidiary (Hospital del Ronquillo, S. de R.L. de C.V.) and in accordance with
needs to be US GAAP - FAS 112-, Mexcananea records the liability for postre-
tirement medical benefits based on actuarial calculations under the projected
unit credit method and using real interest rates.

When there is a significant reduction in personnel due to the restructuring of
the labor force or the closing of a plant, the corresponding indemnity costs,
net of the corresponding reduction in the projected benefit obligation and the
related items to be amortized, are charged to results.

Accordingly, the Company is accruing that liability, which at present value
will cover the obligation from benefits projected to the estimated retirement
date of the Company's employees. Indemnity payments are charged to results in
the period in which they are made.
g. Income tax, asset tax and employee statutory profit-sharing -

Income tax and employee statutory profit-sharing are recorded in the results of
the year in which they are incurred. Deferred income tax assets and liabilities
are recognized for temporary differences resulting from comparing the book and
tax values of assets and liabilities plus any future benefits from tax loss
carryforwards. Deferred income tax assets are reduced by any benefits that, in
the opinion of management, are not likely of being realized. Deferred emplo-
yees' statutory profit-sharing is derived from temporary differences between
the accounting income and income for employees' statutory profit-sharing pur-
poses.

Asset tax paid that is expected to be recoverable is recorded as an advance
payment of income tax and is presented in the balance sheet together with defe-
rred income tax.

h. Foreign currency balances and transactions -

Monetary assets and liabilities denominated in foreign currency are translated
into US dollars at the applicable exchange rate in effect at the balance sheet
date  Foreign currency transactions are recorded at the applicable exchange
rate in effect at the transaction date. Exchange fluctuations are recorded as
a component of net comprehensive financing income (cost) in the consolidated
statements of operations.

i. Revenue recognition -

Most of the Company's copper is sold as refined metal under annual contracts or
 on a spot sale basis. The balance of the Company's copper production is sold
in the form of concentrate under contracts of one to three years duration.
Silver and gold are sold under monthly contracts or in spot sales. Revenues are
recorded primarily in the month the product is shipped to customers based on
prices established in sales contracts.

j. Hedging activities -

Derivate instruments may be used to manage exposure to market risk from changes
in comoodity prices (metal and energy products), interest rates or the value of
the Company's assets and liabilities. To qualify for hedge accounting deriva-
tive instruments must be designated as a hedge in writing at acquisition or
inception of the contract. In addition, such instruments must be periodically
evaluated and deemed to be "highly effective" at reducing the risk  associated
with the exposure being hedged. Any ineffectiveness of the hedge is reported in
current earnings. Derivative financial instruments that fail to qualify for
hedge accounting are carried at fair value and all unrealized gains or losses
are recognized in earnings.

The Company's derivative transactions during 2004 and 2003 were limited in
volume and restricted to risk management. The Company does not maintain or
issue financial instruments for speculative purposes. Decisions with respect
to each transaction and to the overall hedging policies are made by an Execu-
tive Risk Committee. The objective of the committee, which is currently com-
prised of the Chairman of the Board, the Chief Financial Officer and the
Assistant Director of Risk Management, is to ensure that the risks and benefits
have been appropriately assessed.



The Company enters into swap and option transactions or a combination of both
to reduce or  eliminate the risk of purchase or sales price fluctuations. For
instance, for the purpose of reducing the risk of fluctuations in metal prices,
the Company may purchase put options or create synthetic put options to reduce
or eliminate the risk of metal price declines below the option strike price on
a portion of its anticipated future sales. Options and futures contracts are
carried at fair value with unrealized gains or losses recognized in current
earnings. Realized gains or  losses from the sale or exercise of options and
from the settlement of futures contracts are recognized in the period in which
the underlying hedged production is sold.

k. Swap agreements -

Swap agreements limit the effect of changes in the price of the underlying
transactions. The Company's swap agreements generally do not meet hedge accoun-
ting criteria and are carried at fair value with unrealized gains or losses
recognized in current earnings. The Company enters into interest rate swap
agreements to limit the effect of increases in interest rates on floating rate
debt. The current differential to be paid or received as interest rates change
under any such  agreement is recorded in interest expense. Diesel fuel swap
agreements are entered into to limit the effect of increases in the price of
diesel fuel. The differential to be paid or received as diesel fuel prices
change is recorded as a component of cost of sales. Foreign currency swap
agreements are entered into to limit the effect of exchange rate changes on
future cash flow  obligations denominated in foreign currencies. The difference
to be paid or received as exchange rates change is included in the cost of the
input for which it was obtained.

l. Estimates
 The accounting policies followed by the Company require that management make
certain estimates and use certain assumptions that affect the amounts reported
in the consolidated financial statements and the accompanying notes. Although
these estimates are based on management's best knowledge of current circums-
tances, actual results may differ.

m. Impact of New Accounting Standards:

Effective January 1, 2003, the Company adopted Statement of Financial Accoun-
ting Standards (SFAS) No. 143, "Accounting for Asset Retirement Obligations".
This statement requires the fair value of a liability for an asset retirement
obligation be recognized in the period in which it is incurred. The liability
is measured at fair value and is adjusted to its present value in subsequent
periods as accretion expense is recorded. The corresponding asset retirement
costs are capitalized as part of the carrying value of the related long-lived
assets and depreciated over the asset's useful life. The adoption of SFAS No.
143 did not have a material effect on the Company's financial statements.

Effective January 1, 2003, the Company implemented SFAS No. 145, "Rescission of
SFAS Nos. 4,44 and 64, Amendment of SFAS 13, and Technical Corrections", under
which gains and losses from extinguishment of debt are classified as extraor-
dinary items only if they meet criteria outlined in Accounting Principles
Bulletin No. 30.

Effective January 1, 2003, the Company adopted SFAS No. 146, "Accounting for
Costs Associated with Exit or Disposal Activities" (SFAS 146), which addresses
financial accounting and reporting for costs associated with exit or disposal
activities and nullifies Emerging Issues Task Force (EITF) Issue No. 94-3,
"Liability Recognition for Certain Employees Termination Benefits and Other
Costs to Exit an Activity (including Certain Costs Incurred in a Restructu-
ring)". The adoption of SFAS No. 146 did not have a material effect on the
Company's financial statements.

Effective January 1, 2003, the Company adopted SFAS Interpretation No. 45,
"Guarantor's Accounting and Disclosure Requirements for Guarantees, Including
Indirect Guarantees of  Indebtedness of Others" ("FIN 45"). FIN 45 requires that
upon issuance of a guarantee, the Company must disclose and may be required to
recognize a liability for the fair value of the  obligation it assumes under
that guarantee. The initial recognition and measurement requirement of FIN 45
is effective for guarantees issued or modified after December 31, 2002. The
adoption of FIN 45 did not have a material effect on the Company's financial
statement.

Effective January 1, 2003, the Company adopted SFAS No. 148, "Accounting for
Stock-Based Compensation - Transition and Disclosure" (SFAS 148), SFAS No. 148
des not alter the provisions of SFAS No. 123, nor does it require stock-based
compensation to be measured under the fair-value approach under SFAS No. 123.
The Company uses the disclosure only provisions of SFAS No. 123. The adoption
of SFAS No. 148 did not have a material effect on the  Company's financial
statements.

Effective February 1, 2003, the Company adopted FASB Interpretation No. 46,
"Consolidation of Variable Interest Entities" ("FIN 46"). FIN 46 addresses
consolidation by business enterprises of variable interest entities. Under this
interpretation, certain entities known as Variable Interest Entities ("VIEs")
must be consolidated by the primary beneficiary of the entity. The primary
beneficiary is generally defined as having the majority of the risks and re-
wards arising from the VIE. For VIEs in which a significant (but not majority)
variable interest is held, certain disclosures are required. The Company has
not entered into any arrangements or made any investments which qualify as a
VIE in the period from January 31, 2003 to March 31, 2004 nor is it party
to any such arrangements. The adoption of FIN 46 did not have a material impact
on our consolidated financial position, results of operations or cash flows.

In April 2003, the FASB issued SFAS No. 149, "Amendment of Statement 133 on
Derivative Instruments and Hedging Activities". This Statement amends and
clarifies financial accounting and reporting for derivative instruments, inclu-
ding certain derivative instruments embedded in other contracts (collectively
referred to as derivatives) and for hedging activities under FASB Statement No.
133, Accounting for Derivative Instruments and Hedging Activities. The Company
adopted the provisions of SFAS No. 149 on July 1, 2003, which did not have a
material effect on the Company's financial statements.

In May 2003, the FASB issued SFAS No. 150, "Accounting for Certain Financial
Instruments with Characteristics of both Liabilities and Equity". This
State-ment  establishes standards of how an issuer classifies and measures
certain financial instruments with characteristics of both liabilities and
equity. It requires that an issuer classify a financial instrument that is
within its scope as a liability (or an asset in some circumstances). This
Statement is effective for financial  instruments entered into or modified
after May 31, 2003, and otherwise is effective July 1, 2003. The Company
adopted the provisions of SFAS No. 150 on July 1, 2003, which did not have
a material effect on the Company's financial statements. The Company has
no financial instruments during the period June 1 through June 30, 2003,
which would have required adoption of this SFAS prior to July 1, 2003.

NOTE 4 STOCKHOLDERS' EQUITY:

At March 31, 2004, the Company's capital stock amounted to $431,536 represented
by 769,604,346 shares, of which 630,000,000 Class I correspond to the fixed
portion and 139,604,346 Class II shares to the variable portion.

Dividends paid are not subject to income tax if paid from the Net Tax Profit
Account (CUFIN). Any excess over this account is subject to a tax equivalent
to 49.25% and 47.06% depending on whether paid in 2004 and 2005, respectively.
The tax is payable by the company and may be credited against its income tax
in the same year or the following two years. Dividends paid are not subject to
tax withholding. In the event of a capital reduction, any excess of stock-
holders' equity over capital contributions, the latter restated in accordance
with the provisions of the Income Tax Law, is accorded the same tax treatment
as dividends.

NOTE 5 - INCOME TAXES, ASSET TAX AND EMPLOYEE STATUTORY PROFIT SHARING:

In accordance with Mexican tax law, the Company is subject to asset tax and
income tax, which  take into consideration the taxable and deductible effects
of inflation. Through December 31, 2001, the Mexican income tax rate was 35%
with the obligation to pay 30% currently and the option of deferring the rema-
inning 5% until profits are distributed. The new tax law enacted January 1,
2002, eliminated the option to defer the portion of the income tax payment and
reduces the 35% tax rate by one percentage point each year until it reaches
32% in 2005. The deduction for employee statutory profit-sharing and the obli-
gation to withhold taxes on dividends paid to individuals and foreign residents
was also eliminated.

Asset tax is calculated by applying 1.8% to the Company's asset position, as
defined in the law, and is payable only to the extent that it exceeds the in-
come tax payable for the same period, If in  any year asset tax exceeds the
income tax payable, the asset tax payment for such excess may be reduced by
the amount by which the income tax exceeded asset tax in the three preceding
years and any required payment of asset tax is creditable against the excess
of the income tax over asset tax of the following ten years.

Taxable income- The principal items which affect the determination of taxable
income of  Mexican companies are the differences between purchases and cost of
sales, recognition of the effects of inflation on depreciation and on monetary
assets and liabilities through the inflationary component, which differ for
book and tax purposes.

MM and its subsidiaries obtained authorization to file a consolidated income
and asset tax return. The resulting benefit is recognized in MM.

The Company calculates employee statutory profit-sharing using the guidelines
established in the Income Tax Law.

NOTE 6 - FINANCIAL INSTRUMENTS:

a. Fair value of financial instruments -

For certain of the Company's financial instruments, including cash, accounts
receivable, accounts payable and accrued liabilities, the carrying amounts
approximate fair value due to their short maturities.


b. Concentration of risk -

Financial instruments, which potentially subject the Company to a concentration
of credit risk, consist primarily of cash and cash equivalents, short-term
investments and trade accounts receivable.

The Company invests or maintains available cash with various high quality banks
principally in Mexico and US or in commercial paper of highly-rated companies.
As part of its cash management process, the Company regularly monitors the
relative credit standing of these institutions and, by policy, limits the
amount of credit exposure to any one institution. In the normal course of its
activities, the Company grants credit to its customers. Although the accounts
receivable resulting from these transactions are not guaranteed, the Company
has not had any significant portfolio recovery problems.

NOTE 7 - CONTINGENCIES AND COMMITMENTS:

The Company is involved in various legal proceedings derived from its normal
operations. However, according to management, a reasonable amount has been
reserved to cover any individual or collective court decisions in connection
with these proceedings.

NOTE 8 - RELEVANT EVENT:

On February 3, 2004, GMEXICO, the largest stockholder of Southern Peru Copper
Corporation (SPCC), presented a proposal regarding the possible sale to SPCC
of all the shares of GMEXICO's subsidiary, MM, representing 99% of MM's
outstanding shares, in return for the issuance of additional shares of SPCC.
MM holds substantially all of GMEXICO's Mexican mining assets.

SPCC has formed a special committee of Disinterested Directors, comprising of
member of its Board, to evaluate whether the proposal is in the best interests
of the stockholders of the Company. GMEXICO notes that there can be no assu-
rance as to whether agreement can be reached with regard to this transaction.

If consummated, the transaction would result in the Company having a single
class of common stock, listed on the New York and Lima stock exchanges.
