COMPAÑIA DE MINAS BUENAVENTURA S.A.A. is a leading mining company producing precious metals and
holding mining rights in Peru.
Since its inception in 1953, Buenaventura has focused on exploration and exploitation activities on its
own and through joint ventures. Buenaventura is also an important shareholder of Minera Yanacocha
S.R.L., the leading gold producer in Latin America, and Sociedad Minera Cerro Verde S.A.A, an important
copper company in Perú, and ranks amongst the world’s top ten precious metals producers.
This document contains true and sufficient information regarding the business development of Compañia de Minas
Buenaventura S.A.A. during year 2005. Without detriment to the issuer’s liability, the undersigned assume full
responsibility for its content in conformity with the applicable legislation.

CHAIRMAN’S
LETTER
governance practices, which have maintained constant
contact with our shareholders, while carrying out
activities in the most open and transparent manners
possible. We also believe that the strategy of
standardizing the rights and obligations of the two
classes of shares that we had in 1996 by replacing them
with one, “common” class of shares has significantly
contributed to an increase in Buenaventura’s share
value and liquidity.
Dear Fellow Shareholders,
Nearly a decade ago, on May 15, 1996, to be precise,
Buenaventura listed its shares on the New York Stock
Exchange. As mentioned in our 1996 Annual Report,
May 15th was indeed a memorable day for all of us who
work at Buenaventura. After 43 years in the mining
industry, we became the first Latin American mining
company to trade on the New York Stock Exchange. Just
as significant as being listed on the prestigious NYSE,
or perhaps more important, was the favorable response
by investors who enthusiastically purchased the
Buenaventura’s American Depository Receipts (ADRs).
Results from operations have been good, not only as a
result of higher international precious metals prices for
the specific metals we produce, but also due to our
increased levels of production and the promising results
of our successful explorations campaigns. These have
resulted in the discovery of additional ore tonnages,
which are considerably greater than those extracted
during the year translating into higher reserves in three
of our mines: Julcani, Orcopampa and Uchucchacua.
Today, at the time of drafting this letter for the 2005
Annual Report, we can say with great satisfaction that
our shares have been widely accepted by the market
and the price of our shares has gained considerably.
On the occasion of our 10th anniversary on the NYSE,
we were invited for a second time– the first was in 2003
when Buenaventura S.A.A. celebrated its golden jubilee
– to ring the NYSE’s Closing Bell to mark the closing of
trading on March 6, 2006. We accepted the invitation
with great pride, and wish to express our gratitude to
the New York Stock Exchange’s Management for this
gesture of recognition.
Special mention should be made to the construction
of the hydro-metallurgical circuit for the
complementary treatment of ore from Uchucchacua,
the completion of which is scheduled for the first
quarter in 2006. In fact, we expect to have it fullyoperational by the time this Annual Report reaches our
shareholders.
At the beginning of 1996 the price of gold, our main
product, was already approaching the US$ 400 / oz
mark, which means that the increase we see today in
our share price cannot be attributed only to a rise in
the price of our products. In our opinion, the increase
in our stock price is mainly the result of two factors: First,
the prudent management of operations, discussed in
greater detail later on in this Annual Report, has resulted
in a progressive production increase, and secondly, it is
a reflection of the result of meticulous corporate
In connection with our search for technological
innovations for the complementary treatment of these
minerals, we have already had the opportunity to
experiment with the hydro-metallurgical process using
oxidized ores with promising results. We subsequently
proceeded to review the old mine workings where we
stopped exploitation work upon encountering oxides
that were not amenable for flotation. It would appear
that we have large reserves of these oxide types, which
can now be treated using this new circuit.

Buenaventura’s ADS Performance
We think that it is of interest to our shareholders to
know that throughout the course of the last five
years, our Chipmo mine in Orcopampa has reached
a cumulated production of over one million ounces
of gold – undoubtedly a milestone for any gold mine.
The additional discovery of new reserves in the
Chipmo mine, our main producer, apart from other
interesting projects in its surrounding areas, have
transformed this operation into an entire mining
district with enormous potential for the future. Of
immediate interest is the development of the
Poracota area, 20 kilometers west of Orcopampa. The
Explorations chapter offers a more detailed
description of our findings in Poracota. We shall only
venture to say in this letter that we expect to
commence exploitation activities in this deposit by
mid-2006, and this should contribute to further
increases in our production. Initially it will be a smallscale operation, designed to grow gradually in the
future.
us to test different alternatives to process the minerals
found in this area. As our shareholders are well-aware,
these minerals are complex and typically contain high
levels of arsenic, which need to be eliminated in an
environmentally-friendly manner.
The subsidiary companies through which
Buenaventura manages its production activities have
functioned according to the pre-established programs.
In this context, Sociedad Minera El Brocal’s
performance has been particularly successful:
production not only increased dramatically, but was
also boosted in value terms due to high silver, lead and
zinc prices. Thanks to profitable financial results, the
Company was able to complete the construction of a
800m ramp as part of the Marcapunta Oeste ore
deposit development program.
Minera Yanacocha, is of the belief that this
extraordinarily high output cannot and should not be
maintained – and we agree. We believe that production
levels should be reduced in Minera Yanacocha to target
an average of approximately 2.5 million oz of gold, while
focusing on the installation of a plant to treat sulfide
gold ores as soon as possible. Minera Yanacocha has
already approved the construction of this plant, and it
represents an important project insofar as it will extend
the life of the mine for many more years to come.
Minera Yanacocha S.R.L., (43.65% Buenaventura)
operated by Newmont Mining Co. (51.35%) produced
3,333,088 oz gold in 2005.
We are very pleased to inform our shareholders that our
auditors at Ernst & Young consider our condition as a
“parent company”, by virtue of our 18.3% interest in
Minera Cerro Verde, to be of “significant influence”. As a
consequence, as of fourth quarter 2005, Cerro Verde’s
financial results have been included in our Financial
Furthermore, the reporting period saw the completion
of a processing plant to treat copper ore with a 1000
tpd capacity at El Brocal. This should be in operation by
mid–2006, and allow us not only to capitalize on high
copper prices, but perhaps more important, will permit

is another heartening step forward. We hope that these
negotiations not only come to a happy end, but also
are concluded in the very short-term, hopefully before
the upcoming Presidential elections.
Apart from Buenaventura, Cerro Verde’s other
shareholders are: Phelps Dodge (53.6%), Sumitomo
(21%), and a number of local shareholders who hold
approximately a 7.2% interest.
As can be appreciated so far, the country’s economic
situation is highly satisfactory, and we expect that it will
continue to be so in the future. Notwithstanding all the
good news, the upcoming general elections scheduled
to take place in April of this year have brought a
temporary sense of uncertainty with respect to the
political future of the country. However, this is a
relatively normal occurrence in most pre-election
seasons. Nevertheless, we are confident that whatever
the outcome of these elections, the country’s economy
will continue its upward trend, and that it will at least
match, if not improve, the pace of growth experienced
over the course of the last five years.
The Peruvian economy grew at a rate of 6.7 % in 2005.
Perhaps, more important than the annual growth is the
fact that since 2001, the Peruvian economy has grown
at a constant rate of over 4% per year during the last
five years. 2005 inflation averaged 1.5% and foreign
currency reserves at the Banco Central de Reserva
reached a record high of 14,097 million U.S. Dollars. The
fiscal deficit is estimated to be in the order of 0.4% of
GDP, which signifies that in its totality, the economic
scenario is gratifying, and we hope that this trend will
continue into the future.
In closing, we would like to express our heartfelt thanks
to each and every one of our workers, engineers and all
of our collaborators for their dedication and enthusiasm
in their day-to-day work.
The construction of the Camisea gas pipeline,
transporting gas from the Peruvian jungle to the coast
has been completed. It is expected that final
completion and operation of this ambitious project will
have the effect of tilting the hydrocarbon balance which to date has been grossly deficient – by reversing
it until it shows a surplus.
We would also like to take this opportunity to express
our sincere gratitude to our shareholders for their
unfailing support and interest in our business
activities.
Xstrata’s involvement in the Las Bambas copper ore
deposit in southern Peru and CVRD’s participation in the
Bayovar phosphate deposit in the north of the country
is very encouraging. The participation of Río Tinto in the
copper ore deposit of La Granja is likewise very welcome.
On another note, the agreement reached with respect
to the Free Trade Agreement between Peru and U.S.A

ENVIRONMENT
Our contributions are channeled through agreements
with local and regional governments. With respect to
energy, we are supporting the execution of studies and
initiatives related to rural electrification to benefit towns
and settlements located in the areas surrounding our
mining operations and projects. This is done through
agreements with the communities themselves and the
respective local and regional governments.
During 2005, we continued to carry out our mining
activities in accordance with the Environmental
Management System (EMS) and ISO 14001 standards
in all of our operations. The EMS was revalidated in the
Uchucchacua mine and re-certified in Orcopampa,
through the active participation of Germanischer
Lloyd. At Julcani, with the support of Qualitas
Consultores, we are beginning to implement the EMS
as part of the site’s Closure Plan.
2 Water and Forestation
Company policy on the use of water enforces maximum
optimization in the productive process. Permanent
recirculation of water has made it possible for us to
reduce our water consumption in the productive process.
The company has also supported the surrounding
villages by helping them with infrastructure and by
installing potable water systems. With regard to
forestation, Buenaventura has established a number of
nurseries in conjunction with the communities,
authorities and local governments. The idea is to reach
mutually beneficial agreements designed to contribute
to the improvement of the people’s living conditions.
We have amended and drafted the Mine Closure Plans at
feasibility level for both the mining units and exploration
projects, respectively. To this end, the company has entered
into agreements with experienced specialist companies
that are duly authorized to undertake such work by
Peruvian mining authorities. Once completed, these Plans
will be submitted to the Ministry of Energy and Mines
during the second and third quarter 2006.
Environmental permits have been obtained or renewed
for a number of different exploration projects, some of
which are due to commence activities and others whose
permits had expired.
3 Agro-Industry and Tourism
COMMUNITY RELATIONS
We are fully aware that mining activity, typically located
in sites at over 3,500 m.a.s.l., will not meet the population’s
demand of job opportunities single-handedly. It is for
this reason that our efforts are focused on promoting and
improving activities related to farming, camelide-raising,
stockraising (for meat and dairy) and activities designed
to teach people to work with camelide fibers for the
textile industry. The important thing is to improve the
quality and design of the products they offer. Another
highly promising line of business is the ecological fur

In a concerted effort with the Ministry of Transport
(Provias), and other companies with operations in the
basin (Raura, Los Quenuales), we are supporting the
work to refurbish the Sayán–Oyón road. These projects
also include providing maintenance to the road that
connects Uchucchacua with Cerro de Pasco and other
rural roads.
Buenaventura also participates with the community via
supporting initiatives geared towards constructing and
improving rural schools. Another line of action is directed
towards improving the level of education, particularly in
mathematics, in various schools in Huancavelica. This also
entails organizing teacher–training courses to place more
emphasis on subjects related to environmental
protection and natural resources (especially in
connection with the mining industry). A number of
school grants have also been awarded.
Work is continuing at Orcopampa too, under the
framework of the agreement entered into with the
Peasant Community of Orcopampa. The company
provides support in the design of profiles for a series of
projects created to benefit the community annexes.
Agreements have been signed with the communities
of Chilcaymarca and Umachulco, linked to the
Orcopampa mine and the Poracota Project, respectively.
Nutrition is a particularly worrisome concern in high
altitude areas. Our intervention here is in concert with local
authorities, with courses on ways to optimize the use of
local foods, while encouraging the intake of dairy products.
As far as health is concerned, Buenaventura offers support
in the construction of medical posts together with the help
of community members themselves. The company also
works jointly with the medical posts and local authorities
to organize health campaigns in the surrounding
communities and villages. It is the State’s responsibility to
provide basic medical coverage for the Peruvian people.
Our role in this particular field is to aid the health sector in
reaching those who most need it, within our area of
influence and to the extent that it is reasonably possible.
In Huancavelica, specifically in the area of Julcani–
Recuperada, Buenaventura transferred the
Huancavelica Land Transport Terminal and the Lircay
Technological Institute to the local authorities.
In spite of restrictions that limit the activities of a number
of public institutions, we are continuing with the
agreement to improve the Chincha – Huancavelica road.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
As of December 31, 2003, 2004 and 2005
1. Business activity
Compañía de Minas Buenaventura S.A.A. (hereafter “Buenaventura”) is a public company incorporated in 1953. It is engaged in the
exploration (individually and in association with third parties), extraction, concentration and commercialization of polymetallic ores.
Buenaventura operates two mining units in Peru (Uchucchacua and Orcopampa) and has a controlling interest in three Peruvian
mining companies that own the Colquijirca, Antapite, Ishihuinca, Shila and Paula mines. In addition, the Company holds direct and
indirect interests in a number of other mining companies; the most important of such interests is in Minera Yanacocha S.R.L. (hereafter
“Yanacocha”) and Sociedad Minera Cerro Verde S.A.A. (hereafter, “Cerro Verde”), see note 12. Buenaventura also owns an electric
power distribution company and a mining engineering services consulting company.
In 1999 and 2001, Buenaventura decided to suspend exploitation activities in the Julcani and Recuperada mines, respectively, and
only continue to carry out exploration activities. Mineral found in Julcani during exploration activities is treated and sold. Due to
the increase in the market quotations of metals, Buenaventura’s management has decided to reinitiate its exploration activities in
Recuperada during the first quarter of 2006.
As of December 31, 2004 and 2005, the number of employees at Buenaventura and its subsidiaries (together “the Company”), is as

(i) Effective December 30, 2005 and January 2, 2006, Buenaventura acquired 50% and 25% of the capital stock of Minas Poracota
S.A. (Poracota), respectively, in exchange for a payment of US$4,501,000. According to the Shareholders´ agreement signed with
Teck Cominco Perú S.A. (hereafter “Teck Cominco”), if a preliminary study to be prepared by Teck Cominco and Buenaventura,
indicates that there is a probability of obtaining a production greater than 300,000 ounces of gold per year, Teck Cominco will
have the right to recover its position as the owner of the 50% of the capital stock of Poracota and to be the operator of the
project. To this effect, Teck Cominco will prepare a feasibility study with a production of 300,000 ounces of gold, assuming the
cost of this study. If the project were a smaller one, Buenaventura can opt for buying the remaining 25% of the capital stock of
Poracota for US$2,250,000.
2. Significant accounting principles and practices
The consolidated financial statements are prepared based on Accounting Principles Generally Accepted in Peru. Accounting
Principles substantially comprise International Financial Reporting Standards (IFRS), which include International Accounting
Standards (IAS) duly approved by the Peruvian Accounting Standards Board. To the date of the consolidated financial statements,
this Board has approved the use of IAS 1 to 41, and the Interpretations 1 to 33.
The main accounting principles and practices used in accounting for the transactions and in preparing the consolidated financial
statements are:
(a) Presentation Basis The accompanying consolidated financial statements have been prepared from the accounting records of the company, which are
stated in nominal monetary terms of the date of the transactions.
Until December 31, 2004, these consolidated financial statements were maintained in nominal Peruvian currency and adjusted to
reflect changes In the National Wholesale Price Level Index (IPM), according to the methodology approved by the Peruvian
Accounting Standards Board. This methodology required the adjustment of the non-monetary items in the consolidated financial
statements considering their origin date and applying the corresponding Wholesale Price Indexes. Monetary items and foreign
currency-denominated items were not restated because they are stated in currency of acquisition power at the consolidated
balance sheet dates.
Effective year 2005, through Resolution No.031-2004-EF/93.01 enacted on May 18, 2004, the Peruvian Accounting Standards Board
suspended the restatement of the financial statements to recognize the inflation effect. The restated balances as of December 31,
2004 have been considered as initial balances as of January 1, 2005. This accounting treatment has been also adopted by tax authorities
for calculating the income tax for the year 2005. Therefore, the Company has not recognized a result from exposure to inflation in
the income of 2005, while in 2003 and 2004, a gain of S/793,000 and a loss of S/9,847,000, respectively, were recorded.
(b) Use of estimates and assumptions The preparation of financial statements in conformity with generally accepted accounting principles in Peru requires Management
to make certain estimates and assumptions. These estimates and assumptions affect the reported amounts of assets and liabilities
and disclosure of contingent assets and liabilities at the date of the consolidated financial statements, as well as the reported
amounts of revenues and expenses for the years ended December 31, 2003, 2004 and 2005. Actual results could differ from those
estimates.
The most significant estimates in the accompanying consolidated financial statements are the obsolescence supplies reserves, the
useful lives and impairment of long-term assets, the determination of mineral reserves, the recoverability of deferred income tax
and workers’ profit sharing, the accrual for mine closing costs and the fair value of derivates instruments.
(c) Principles of consolidation The consolidated financial statements include the accounts of Buenaventura and the accounts of those subsidiaries in which possess more
than 50 percent equity participation and/or exercises control. All significant inter-company balances and transactions have been eliminated.
The minority interest is presented separately in the consolidated balance sheets and in the consolidated statements of income.
See companies included in the consolidated financial statements in Note 1.
(d) Cash and cash equivalents Cash and cash equivalents include all cash on hand and deposited in banks. For preparing the consolidated statements of cash flows,
cash a balances and cash equivalent includes cash on hand, time deposits and highly liquid investments with original maturities of
three months or less.
(e) Inventories Inventories are stated at the lower of average cost or net realizable value. Net realizable value is defined as the estimated sales price
obtainable in the ordinary course of business, less estimated costs of completion and estimated selling and distribution expenses.
Cost is determined using the average method.
The accrual for obsolescence is based on an item-by-item analysis completed by the Company’s management and related amounts
are charged to expense in the period in which the obsolescence is deemed to have occurred.
(f)) Investments in shares (f
Until December 31, 2002, investments in which the Company’s interest is lower than 20 percent or not exercise significant influence
were stated at cost, less any permanent value impairment. Effective January 1, 2003, the Company has adopted IAS 39, Financial
Instruments - Recognition and Measurement. Under the requirements of this standard, such investments must be recorded at fair
38
value and changes in such value must be separately presented in the consolidated statements of changes in shareholders’ equity.
The Company has recorded a charge to retained earnings by S/5,957,000, corresponding to the initial adoption of this standard. The
corresponding dividends are credited to income when declared.
Investments in entities in which the Company’s ownership is greater than 20 percent but less than 50 percent or exercise significant
influence are accounted for by the equity method, recognizing the Company’s proportionate share in the results of the affiliates in the
consolidated statements of income. The measurement and reporting currency of affiliates is the Peruvian Nuevo Sol, with the exception
of Yanacocha and Cerro Verde whose measurement and reporting currency is the U.S. dollar. The translation of the financial statements
of Yanacocha and Cerro Verde results in exchange differences arising from translating (a) income and expense items at the exchange
rates prevailing on the individual transaction dates, (b) assets and liabilities at the closing exchange rate, and (c) equity accounts at the
historical exchange rates. The net exchange difference is classified in equity until further disposal of the net investment.
The purchase method is used to record business acquisitions. Under this method, the assets and liabilities of acquired businesses are
recorded at fair value and any difference between the amount paid and the fair value of assets and liabilities acquired is recorded as
a mining concession in the caption “property, plant and equipment”(when the difference corresponds to mineral reserves) or goodwill.
For companies in which the Company’s ownership is between 20 and 50 percent, any amount paid in excess of book value of the
shares is reported in the Investment caption. The Company presents in this caption amounts paid over the book value of Yanacocha
and Cerro Verde shares, and amortizes this amount using the units-of-production method, see Note 12.

Property, plant and equipment are stated at cost, net of accumulated depreciation and impairment loss. Maintenance and minor
repairs are charged to expense as incurred. Expenditures that result in future economic benefits, beyond those originally
contemplated in standards of performance for the existing assets, are capitalized.
Depreciation is calculated under the straight-line method of accounting considering the lower of estimated useful lives of the asset
or estimated reserves of the mining unit. The useful lives are the following:
Years
Buildings, constructions and other
Machinery and equipment
Transportation units
Furniture and fixtures
Computer equipment
10 and 20
5 and10
5
8 and 10
4
The useful life assigned and the depreciation method chosen by the Company are reviewed periodically to ensure that the method and
the depreciation period are consistent with the economic benefit and life expectations for use of property, plant and equipment items.
(h) Exploration and mine development costs Exploration costs are charged to expense as incurred. When it is determined that a mineral property can be economically developed,
the costs incurred to develop it, including the costs to further delineate the ore body and remove overburden to initially expose
the ore body, are capitalized. In addition, expenditures that increase significantly the economic reserves in the mining units under
exploitation are capitalized. Mine development costs are amortized using the units-of-production method, based on proven and
probable reserves. On-going development expenditures to maintain production are charged to operations as incurred.
(i) Mining concessions The mining concessions balance corresponds to the amounts paid in excess of fair value of net assets acquired in the purchase of
Compañía de Exploraciones, Desarrollo e Inversiones Mineras S.A.C. - CEDIMIN (Cedimin), Inversiones Colquijirca S.A. (Colquijirca),
Sociedad Minera El Brocal S.A.A. (El Brocal), Minera Paula 49 S.A.C. (Paula) and Minas Poracota S.A.( Poracota). The mining concessions
are shown as a part of the property, plant and equipment caption and represent the ownership of the mining sites which contains
the mineral reserves acquired. The mining concessions are amortized using the units-of-production method, based on the proved
and probable reserves.
Annually, the Company reviews the carrying amounts of mining concessions and assesses whether any potential impairment issues
exist respective to recoverability. If it is evident that the mining concessions are impaired, the Company provides for the impairment
loss in the consolidated statements of income.
(j) Impairment of assets The Company reviews for and evaluates the potential impact of impairment on its assets when events or changes in circumstance
occur that indicate the book value may not be recoverable. An impairment loss is recognized for the amount by which the book
value of an asset exceeds the higher of its net selling price or value in use. The value in use of an asset is generally calculated as the
present value of the estimated future cash flows expected to be earned from continual use of the asset and from its disposal at the
end of its useful life. An impairment loss recognized in a previous year is reversed if events or changes occur that indicate the
estimates used when the impairment loss was recognized should be adjusted to reflect a more favorable cash flow scenario. The
future cash flow assumptions used include, among other items, estimates of recoverable ounces and metric tones, estimates of
realizable prices and costs, and estimates of production quantities. Assumptions in which estimated future cash flows are based are
subject to risk and uncertainty.
Differences between assumptions and market conditions and/or the Company’s development profile could have a material effect
on the financial situation and results of operations of the Company.
39
(k) Accruals An accrual is recognized only when the Company has a present obligation (legal or implicit) as a result of a past event, it is probable that
resources of the Company will be required to settle the obligation, and the related amount can be reasonably estimated. Accruals are
revised periodically and are adjusted to reflect the best available information at the date of the consolidated balance sheets.
(l) Accrual for mine closing costs See note 3(a) for further information about the accounting change.
(m) Deferred stripping costs See note 3(b) for further information about the accounting change.
(n) Recognition of revenues, costs and expenses Sales of concentrates are recorded at the time of shipment in the case of export sales or, when the concentrates physically pass to
the customer’s warehouse for domestic sales. Sales are recorded at estimated value according to preliminary billings. The sales
amount is then adjusted in the period in which final billings are released. When it is evident that the quotations to be used in the
final billings are lower than those used in preliminary billings, the excess is reversed in the period in which final prices are known.
Sales of ounces of gold are recorded at the time of the delivery and passage of the title rights of such ounces to the client.
Costs and expenses are recorded on an accrual basis.
(o) Foreign currency transactions Transactions occurring in a foreign currency are recorded in local Peruvian currency by applying to the foreign currency amount
the exchange rate at the transaction date. Exchange gains and losses resulting from differences between the closing exchange rate
and the exchange rate used to initially record transactions, are recognized in the consolidated statements of income in the period
in which they arise.
(p) Income tax and workers’ profit sharing The current income tax and workers’ profit sharing balances are calculated and recorded pursuant to current legal regulations
effective in Peru. Following the balance sheet liability method, the Company recognizes the effect of temporary differences between
book and tax basis of assets and liabilities to the extent that such differences result in a deferred tax liability. If a deferred asset arises,
it is not recognized unless it is more likely than not that it will be recoverable.
(q) Contingencies Loss contingencies are recorded in the financial statements when it is probable their occurrence and they can be fairly determined.
In other case, they are only disclosed in notes to the financial statements.
Contingent assets are not recognized in the financial statements; however, they are disclosed in notes to the financial statements
if it is probable that such contingent assets will be realized.
(r) Derivative instruments Until December 31, 2002, the Company used to disclose in notes to the consolidated financial statements the fair value of the
derivative instruments. Effective January 1, 2003, IAS 39, Financial Instruments - Recognition and Measurement, is in force. Following
the description of the changes resulting from the adoption of this standard:
-
The fair value of derivative contracts qualifying as cash flow hedges are reflected as assets or liabilities in the consolidated
balance sheets. To the extent these hedges are effective in offsetting forecasted cash flows from the sale of production, changes
in fair value are deferred in an equity account. Amounts deferred in such account are reclassified to Sales when the underlying
production is sold. The effect of the initial adoption of this standard by the subsidiary El Brocal resulted in a credit to the equity
account “unrealized loss on derivative instruments” of S/1,742,000.
- The fair value of derivative contracts not qualifying as cash flow hedges are reflected as assets or liabilities in the consolidated
balance sheets. Changes in fair values are recorded in the caption “gain (loss) from Change in the Fair Value of Derivative
Instruments” in the consolidated statements of income. The effect of the initial adoption of this standard resulted in a charge
to retained earnings of 2003 by S/458,189,000.
- Gain and losses on derivative contracts qualifying as normal sales are initially deferred in the consolidated balance sheets and
then recognized in income in the years in which the Company makes a physical delivery of the committed ounces of gold and
tones of minerals, see note 34(b).
(s) Treasury shares The Company has common and investment shares under treasury. The nominal values of these shares are presented net of the
capital stock and investment shares amounts.
The effect of the dividends income arising from the treasury shares held by a subsidiary are eliminated in the consolidated
financial statements.
(t) Basic and diluted earnings per share Basic and diluted earnings per share have been calculated based on the weighted average number of common and investment
shares outstanding at the date of the consolidated balance sheets; treasury shares have been excluded from the calculation.
(u) Comparative financial statements For improving the presentation of Consolidated Financial Statements, the company has made some reclassifications for the years 2003 and
2004.
40
-
The amortization of goodwill of S/910,000 in 2003 and S/994,000 in 2004, which used to be presented as other income (expenses)
net, is currently presented as operating expense.
-
The realized deferred income from sale of future production of S/68,837,000 in 2004, which used to be presented as other
income (expenses), is currently presented as an operating revenue.
-
The mining concessions of S/151,345,000 have been reclassified from the mining concessions and goodwill caption to the
property, plant and equipment caption of the consolidated balance sheet as of December 31, 2004.
-
The amortization of mining concessions of S/14,668,000 in 2003 and S/14,604,000 in 2004, have been reclassified from the
amortization of mining concessions and goodwill caption to the depreciation and amortization caption of the consolidated
statements of income.
(v) New accounting pronouncements Through Resolutions N° 034-2005-EF/93.01 and N° 036-2005-EF/93.01 dated March 2, 2005 and December 15, 2005, respectively,
the Peruvian Accounting Standards Board (CNC in Spanish), approved the International Accounting Standards (IAS) revised and the
International Financial Reporting Standards (IFRS) issued by the International Accounting Standards Committee. These standards
are in force in Peru effective January 1, 2006.
Through Resolution N° 038-2005-EF/93.01 of February 3, 2006, CNC approved to suspend until December 31, 2006, the mandatory
application of the IAS 21 “Effect of the Variations in the Exchange Rates of Foreign Currencies” (revised in 2003), related to the
identification and use of a functional currency. As well, CNC resolved to maintain the equity method in the preparation of the
individual financial statements.
The Company is evaluating the effects in its consolidated financial statements from the adoption of the revised IAS and the new IFRS issued.
3. Change in an accounting principle
(a) Effective January 1, 2003, the Company and its affiliated Yanacocha made an accounting change related to the provision for mine
closure. Following, we describe the accounting changes, and the cumulative effect as of January 1, 2003:
(i) Until December 31, 2002, the Company used to record the obligation for mine closure when the related amount could be
fairly estimated, which normally occurred at end of the life mine. Effective January 1, 2003, the Company records such
liability when a legally enforceable obligation arises for mine closing, independently of the full depletion of the reserves.
Once such obligation has been appropriately measured, it is recorded by creating a liability equal to the amount of the
obligation and recording a corresponding increase to the carrying amount of the related long-lived assets (development
costs and property, plant and equipment). As time passes, the amount of the obligation changes, recording an accretion
expense; additionally, the capitalized cost is depreciated and/or amortized based on the useful lives of the related asset.
Any difference in the settlement of the liability will be recorded in the results of the period in which such settlement
occurs. The changes in the fair value of the obligation or useful life of the related assets that occur from the revision of the
initial estimates should be recorded as an increase or decrease in the book value of the obligation and the related longlived asset.
The cumulative effect of this change in accounting principle, net of the workers’ profit sharing, income tax and minority
interest, was a loss of S/20,711,000; this amount is presented in the caption “cumulative effect of change accounting principle
due to mine closing” in the consolidated statements of income.
(ii) Until December 31, 2002, the affiliated Yanacocha used to accrue the mine closing costs and charge to income over the
expected operating lives of the mines using the unit-of-production method. Effective January 1, 2003, Yanacocha records
such obligation using an accounting treatment similar to the one used by Buenaventura and its subsidiaries.
The cumulative effect of the change in the accounting principle was a loss of S/51,584,000, which is presented as “cumulative
effect of change in accounting principle due to mine closing costs” in the consolidated statements of income.
(b) Until December 31, 2004, with the intent to reasonably match revenues and current production costs, El Brocal was deferring
certain costs incurred in the expansion of the Tajo Norte mining site. These costs are commonly referred as “deferred stripping
costs” and are incurred in mining activities that are associated with the removal of waste rock to access the ore body. Costs
related to additional quantities of waste that must be moved to obtain 1 MT of mineral were deferred when the actual waste
material extracted was higher than the estimate; likewise, these costs were amortized when actual waste mineral extraction
was lower than the estimate.
Effective January 1, 2005, El Brocal considers the deferred stripping costs incurred during the production stage as variable
production costs that should be included in the cost of the inventories produced. This accounting change allows El Brocal to
adopt international industry practices.
The cumulative effect of this accounting change, net of workers’ profit sharing, income tax and minority interest, was a loss
of S/10,416,000, which is separately presented in the caption “Cumulative effect of change in accounting principle due to
stripping costs” in the consolidated statements of income. This accounting change had no effect in the consolidated
financial statements of 2004 due to the fact that the stripping costs incurred in such period were treated as in the current
period.
In 2003, this change would have represented in the consolidated statements of income an increase in the operating costs from
S/456,764,000 to S/471,093,000 and a decrease in the net income from S/175,153,000 to S/172,490,000. In addition, the basic
and diluted earnings per share would have decreased from S/1.38 per share to S/1.36 per share.

4. Convenience Translation of Peruvian Nuevos Soles amounts into U.S. dollar amounts
The consolidated financial statements are stated in Peruvian Nuevos Soles. U.S. dollar amounts are included solely for the convenience
of the reader, and were obtained by dividing Peruvian Nuevos Soles amounts by the exchange rate for selling U.S. dollars at December
31, 2005 (S/3.431 to US$1), as published by the Superintendencia de Banca y Seguros (Superintendent of Bank and Insurance, or
“SBS”). The convenience translation should not be construed as a representation that the Peruvian Nuevos Soles amounts have
been, could have been or could be converted into U.S. dollars at the foregoing or any other rate of exchange.
5. Foreign currency transactions
Translations to foreign currency are completed using exchange rates published by the Superintendencia de Banca y Seguros y AFP.
As of December 31, 2005, the exchange rates published by this Institution were S/3.429 for buying and S/3.431 for selling (S/3.280
for buying and S/3.283 for selling as of December 31, 2004) and have been applied for the assets and liabilities accounts.
As of December 31, 2004 and 2005, the Company had the following assets and liabilities denominated in foreign currency:

Advance was considered unconstitutional; consequently, this advance is no longer in force effective such date. Buenaventura
has applied for its devolution in accordance with the regulations of the Peruvian Tax Code. In management’s opinion, this excess
payment with be recovered in the short-term.
(c) As of December 31, 2004 and 2005, it mainly includes the value added tax originated by the exploration activities of Minera La
Zanja S.R.L. In Management’s opinion, this credit will be offset with the future value added tax liability to be generated when
the exploitation activities begin.

investment in Yanacocha for reporting purposes. The Company increases the investment and recognizes a gain in the share
in affiliated companies as Yanacocha depreciates and amortizes the acquired assets.
The net increase in the participation in Yanacocha’s net income during 2005 compared to 2004 is mainly due to increased sales
of Yanacocha (price and volume), offset by a slight increase in the cash cost per ounce of gold sold. In addition, this participation
is reduced as a consequence of the exchange rate used to convert into Nuevos Soles the participation in Yanacocha’s results,
reported in U.S. Dollars (the exchange rates used for that translation were S/3.302 and S/3.407 per US$1 for as of December 31,
2004 and 2005, respectively). The information related to Yanacocha’s result is shown below:

(h) Legal processes of Yanacocha
Mercury spill in Choropampa In June 2000, a Yanacocha’s contractor spilled approximately 11 liters of mercury nearby Choropampa, located at 84.8 kilometers
from Yanacocha. As a result of the accident, 1,000 Peruvian citizens and the Municipality of Cajamarca sue Yanacocha and other
persons involved at the District Court of the state of Colorado, United States of America (hereinafter “the Court”). The plaintiffs
demand compensations by the damages originated by this spill. In February 2005, Yanacocha responded to this demand.
45
Likewise, approximately 900 Peruvian citizens sued Yanacocha and others evolved at the presence Cajamarca’s judicial authorities.
Those demands claim a financial compensation of US$229,420,000 and S/1,245,000. As of December 31, 2005, Yanacocha has
reached agreements with approximately 40% of the sewers for lower amounts from the initially demanded, reducing significantly
the contingencies originated by this legal process. Additionally, more than half of the remaining plaintiffs that still maintain
legal processes had reached compensations agreements with Yanacocha, before the demands begin. Yanacocha applied to the
Civil Court from the Cajamarca Superior Court the end of this process due to its previews agreements, having obtained favorable
sentences .The sewers have appealed those sentences before the Peru’s Supreme Court, where they remain pending.
Up to this date, Yanacocha considers that it is not possible to predict the final outcome of these demands; however, any effect
related to them will not be significant for that financial statements.
Tax processes Tax authorities have reviewed the income tax and value added tax returns for years 1998 to 2001. As a result of these reviews,
Yanacocha was notified with tax assessments of US$35.0 million, from which Yanacocha recorded an accrual of US$17.5 million
in 2004. With the purpose of eliminating some of these contingencies,Yanacocha filed for the “Sistema Especial de Actualización
y Pago de Deudas Tributarias - SEAP” which allows the payment of incorrectly declared taxes, eliminating fines and accrued
interest at preferential rates, resulting in a payment of US$ 11.5 million.
In the opinion of Yanacocha’s Management and its legal advisors, the accrual recorded is enough to cover the tax contingency.

(i) Economic activity Cerro Verde is engaged in the extraction, production and commercialization of copper in its mining concessions located in the
department of Arequipa, Peru. Currently, Cerro Verde is carrying out the construction of the primary sulfide plant. The investment
in this project is estimated in US$850 million and will allow its copper production increase from 90,000 MT to 300,000 MT.
(j) Acquisition of additional share The Shareholders´s meeting of Cerro Verde held on April 18, 2005 agreed to increase the capital stock by US$440 millions with the
purpose of financing the construction of the primary sulfide plant, which total investment is estimated at US$850 million. This capital
increase permitted Buenaventura to raise its share in Cerro Verde from 9.17% to 18.214%, by a payment of US$154.8 million.
Subsequently, through of additional acquisitions of Cerro Verde´s shares, Buenaventura has increased its total share to 18.299%.
The share increase in Cerro Verde allows Buenaventura to exercise significant influence (faculty to participate in the decisions
related to financial and operational policies), which is evidenced by its representation in the Board of Directors; the participation
in policy-making processes, including participation in decisions about dividends; participation as guarantor of Cerro Verde in
the loan agreements entered by this entity with several foreign banks in connection with the financing of the construction of
the primary sulfide plant; and unrestrictive access to the interim and annual financial information. As a consequence,
Buenaventura has decided to account for its investment in Cerro Verde using the equity method, since this investment no
longer meets the criteria to be recorded at its fair value. Following, we describe the main accounting effects:
-
-
-
The fair value of the investment in Cerro Verde as of January 1, 2005 of S/256,043,000 was reversed with a charge to the
account “Cumulative gain on investments at fair value” and a credit to the captions of investment by S/250,087,000 and
retained earnings by S/5,956,000.
The prior years effects, resulting from the application of the equity method since the date of the initial acquisition occurred
in 1996, are S/69,724,000. This amount is recorded by a charge to the investment caption and by a credit to the retained
earnings caption of 2005. For the years 2003 and 2004, the change would have represented an increase in the share in
affiliated companies in the consolidated statements of income from S/557,558,000 and S/575,858,000 to S/571,734,000
and S/603,453,000, respectively, and an increase in the net income from S/175,153,000 and S/685,650,000 to S/189,329,000
and S/713,245,000, respectively. In addition, the basic and diluted earnings per share would have increased from S/1.38 and
S/5.39 to S/1.49 and S/5.61, respectively.
Buenaventura has recognized an amount of S/197,754,000, as a result of comparing the acquisition cost with the share in
the fair values of the assets and liabilities of Cerro Verde. This amount is included in the investment caption and amortized
based on the proven and probable reserves of Cerro Verde

Guarantees granted On September 30, 2005, Cerro Verde signed some agreements with several export credit agencies and commercial banks in
connection with the financing of US$450 million for the expansion of its operations. The financing requires the granting of
mortgages and pledges over the Cerro Verde´s assets, and that Phelps Dodge, Sumitomo and Buenaventura comply with
maintaining a minimum shareholders’ equity (US$600 million for Buenaventura). The company that does not comply with this
requirements must grant a stand-by letter for the representative of the banks that participate in the financing. Additionally,
shares in Cerro Verde owned by Buenaventura are pledged in favor of such banks.

(b) Stock Appreciation Rights -
The Company has a program under which certain executives earn a cash bonus equal to that executive’s allotted number of
shares multiplied by the difference between the market value at a future date of the Company’s shares and the base price on
the executive’s share. This program remains in effect as long as the executive works for the Company at each program’s settlement
date. The measurement is made at the end of each reporting period based on the current market price of the shares. Compensation
expense is recognized ratably over the vesting period established in each program.
The number of shares units which will be granted to executives subject to the stock appreciation rights bonus in future years,
are as follows:

In 2005, the Company recorded an expense amounting to S/26,883,000 in connection with this program (S/49,594,000 and S/
2,135,000 in 2003 and 2004, respectively), which is recorded in the “general and administrative” caption in the consolidated
statements of income.

The increase in the accrual of 2005 is explained mainly by the new estimation of the closing costs for the Colquirrumi mining unit,
which has not being operating for more than 15 years.
The accrual for mine closing costs is based on studies completed by independent parties, in accordance with current environmental
protection regulations, see note 36(a). The accrual for mine closing costs corresponds mainly to activities that have to be completed
for the restoration of the mining units and affected areas as a consequence of the exploitation activities. The main works that have
to be completed are the land movements, reforestation labor and remove of the mining plants.

The income tax of Buenaventura for 2000 was reviewed by the Tax Administration. As a consequence, Buenaventura received
an assessment that reduced the tax loss carryforward in S/114,001,000. The main issue is that the Company considered certain
revenues (dividends and equity participation) as taxable for determining the tax loss carryforward. In opinion of the Company’s
legal advisors, the assessment does not have solid grounds. It is expected that the Company obtains a favorable opinion in the
administrative process initiated against the assessment.
The 2002 income tax of Cedimin was reviewed by the Tax Administration. As a consequence, Cedimin received an assessment
that modified the tax loss carryforward. The main issue is that Cedimin considered the loss from the sale of its shares in Minera
Huallanca S.A.C. and Minera Yanaquihua S.A by S/27,129,000 as deductible. In opinion of Cedimin´s legal advisors, such assessment
has no solid grounds and therefore, it is expected that Cedimin obtains a favorable opinion in the administrative process initiated
against the assessment.
Additionally, the 2000 and 2001 income tax of Condesa was reviewed by the Tax Administration. As a consequence, the
Company received tax assessments that reduced the tax loss carrryforward by S/1,360,000 in 2000 and by S/16,987,000 in
2001. In both periods, the main issue was that Condesa considered certain revenues - dividends and equity participation
- as taxable for determining the tax loss carryforward. In opinion of Condesa´s legal advisors, such assessment has no solid
grounds and therefore, it is expected that Condesa obtains a favorable opinion in the administrative process initiated
against the assessment.

Due to various possible interpretations of current legislation, it is not possible to determine whether or not future reviews will
result in tax liabilities for the Company. In the event that additional taxes payable, interest and surcharges result from tax
authority reviews, they will be charged to expense in the period assessed and paid. However, in Management’s and legal advisory
opinion, any additional tax assessment would not be significant to the consolidated financial statements as of December 31,
2004 and 2005.
(c) With the purpose of determining the income tax and the value added tax, the transfer prices among related parties and for
transactions with companies domiciled in countries considered tax havens, prices should be supported by documentation
containing information about the valuation methods applied and criteria used in its determination. Based on an analysis of the
Company’s operations, Management and its legal advisors do not believe that the new regulations will result in significant
contingencies for the Company as of December 31, 2004 and 2005.
(d) The Company has the benefit to recover the value added tax of the sales export. Therefore, the tax paid in the acquisitions can
be applied to the tax from its sales or other tax obligations, or request a refund. During the year 2005, Buenaventura has asked
for the refund of the valued added tax for S/39,570,000. On December 31, 2005, the amount pending at refund from the tax
authority of S/8,310,000 is included in the caption “other accounts receivable”.
22. Net sales by geographic region sales agreements
The Company’s revenues primarily result from the sale of precious metal concentrates, including silver-lead, silver-gold, zinc
and lead-gold-copper concentrates and ounces of gold. The following table shows net sales by geographic region:

In 2005, the Company’s three largest customers accounted for 18%, 17% and 13%, respectively, of total sales (20%, 16% and 13%
of total sales in 2004). As of December 31, 2005, 61% of the trade accounts receivable is related to these customers (48% as of
December 31, 2003). Some of these customers have sale contracts with the Company that guarantee them the production
output from specified Company mines at prices based on market quotations or previously agreed. Currently, the production of
the mining units of the Company is subject to such sale agreements; these agreements have various maturity dates but do not
extend beyond December 31, 2012.

The Company has not recorded a deferred income tax and workers’ profit sharing liability originated by the excess of the book
basis over the tax basis of the investments in shares due to the following:
- In the case of the affiliate Cerro Verde under any circumstance - dividend distribution or sale of the investment - the reversal
of the basis difference will not be taxable. Cerro Verde S.A. is a company that quotes its shares in the Lima Stock Exchange
and, in accordance with the Peruvian tax regulations, any gain or losses arising from the disposition of these shares are not
taxable. On the other hand dividends distributions are income tax exempt.
- In the case of the affiliate Yanacocha, Buenaventura’s management has the intention and ability of maintaining the investment
until the date of the depletion of its gold and silver reserves; in this sense, it considers that the temporary difference will
be reverted through future dividends, which are not taxable. On the other hand, Buenaventura’s management has the
ability of reversing the temporary difference, by other form different than dividends distributions, without any tax effects.

(i) According to current Peruvian tax regulations, the equity participation in affiliates, including dividends received, are not taxable.
(ii) According to current Peruvian tax regulations, the loss on derivative instruments is not deductible to the extent it is
generated abroad.
(iii) Effective January 1, 2003, the Company adopted IAS 39, recording the initial effect of the fair value of all derivative contracts in
the equity account: retained earnings (loss). In December 2003 and May 2005, the Company modified certain conditions of its
56
derivative contracts to qualify them as sales contracts; pursuant to this revision, the related loss (negative fair value) became a
temporary difference under current Peruvian tax regulations. The income tax effect has been recorded in each year because
the change of status of a permanent, to a temporary item occurred in December 2003 and May 2005.
(iv) Effective April 1, 2004, the statutory income tax rate in Peru is 30 percent. Until December 31, 2003, the income tax rate was 27
percent. In both periods the workers’ profit sharing rate was 8 percent.

33. Disclosure about information by segments
International Accounting Standard (IAS) 14, requires enterprises to disclose financial information by business and/or
geographical segment. Companies should consider their organizational and management structure and their internal financial
reporting system when identifying segments. Segments are generally defined by the manner in which the Company presents
data to high-level management for their use in evaluating each units past performance. The most important segment is Mining,
which activities are carried out through nine companies. Management considers that these mining companies can be combined
into one reportable mining segment because they show similar financial performance and similar characteristics related to the
nature of their products, the nature of their production process, their clients and legal environment. The electric, mining
consulting and insurance segments are not significant and, therefore, are not considered in the evaluation of business
development. Therefore, management considers that the Company’s only reportable segment is mining.
34. Derivative financial instruments
(a) Derivative contracts Buenaventura holds contracts of derivative instruments with the intention to hedge the fluctuations in metal prices; however,
the Company does not meet all the criteria stated in IAS 39 to account for the derivative instruments as cash flow hedges. The
table below presents a summary of the commodity derivative contracts outstanding as of December 31, 2005:

(ii) Guaranteed with a minimum price of US$6.00 per ounce (only and when silver price is above US$4.00 per ounce.
Related to the derivative instruments contracts maintained during 2003, 2004 and 2005, Buenaventura and El Brocal recorded
the following:
- In January 2003, Buenaventura charged S/458,189,000 to retained earnings and El Brocal credited S/1,742,000, net of
minority interest, to the equity account of “cumulative unrealized loss on derivative instruments” in connection with initial
adoption of IAS 39.
- In 2005, Buenaventura recognized a loss of S/87,872,000 (losses of S/21,937,000 and S/668,030,000 in 2004 and 2003,
respectively) due to the changes in fair value occurred during those periods, which are presented separately in the
consolidated statements of income. In addition, it recognized expenses of S/36,837,000 for the reduction of the Company’s
57
hedge book exposure in 120,000 ounces of gold during the first quarter of 2004. These amounts are presented separately
in the consolidated statements of income.
- In 2004, El Brocal credited S/4,621,000 (a charge of S/8,085,000 in 2003), net of minority interest, to the equity account
“Cumulative unrealized loss on derivative instruments”, due to the changes in fair value occurred during those periods. As
of December 31, 2005, El Brocal does not have derivative contracts to offset the risk of metal price fluctuations.
In addition, the liability presented in the consolidated balance sheets for S/59,138,000 and S/168,017,000 as current and noncurrent portions, respectively, corresponds to the fair value of derivative instruments of Buenaventura as of December 31, 2005
(S/70,927,000 and S/267,852,000 as current and non-current portions, respectively, as of December 31, 2004).
In 2006, Buenaventura’s management has decided to change the nature of the derivative contracts as of December 31, 2005 in
order to qualify them as normal sale contracts. The values of these contracts will be settled on the date that the modifications
are accepted by Buenaventura and the counterparty.
(b) Normal sale contracts of gold zinc and silver
During 2005 and 2003, Buenaventura modified the terms of certain derivative instruments contracts in order to qualify them
as normal sale contracts. Likewise, during 2004, El Brocal made similar changes to their derivative contracts in order to qualify
them as normal sale contracts. As of December 31, 2005, the settled values for these contracts amounting to S/107,079,000 and
S/613,791,000, as current and non-current liabilities, respectively are presented as “deferred income from sale of future
production” in the consolidated balance sheets (S/74,937,000 and S/568,772,000 like current and non-current liabilities as of
December 2004). Since this date, such amount will be credited to income as delivery of the committed ounces of gold occurs.
In 2005, Buenaventura delivered 282,000 ounces of gold as part of the sale contracts above mentioned (198,000 ounces in
2004). As a consequence, Buenaventura recognized revenues of S/92,753,000 in the caption “realized revenue from sale of
future production” in the consolidated statements of income (S/68,837,000 during 2004).
As of December 31, 2005 Buenaventura is committed to sell 1,981,000 ounces of gold at prices ranging up US$451 per ounce
until December 2012. During 2005, El Brocal has complied with all the settled deliveries of zinc and silver.

The information about fair value of the financial instruments, including derivatives, is presented below:
- Current assets and liabilities approximate their fair value due to the short-term maturities of these financial instruments.
- The estimated fair value of the long-term debt is similar to its book value, as the terms and interest rates are from the market.
- The estimated fair value of the derivative contracts is S/227,155,000 and is based on quotations received from the Company’s
counter- parties, see note 34.
36. Commitments and Contingencies
(a) Environmental matters The Company’s mining and exploration activities are subject to environmental protection standards. In order to comply with
these standards, the Company has presented preliminary studies covering of environmental and Environmental Adjustment
and Management Programs (PAMA) for each of the mining units. The Ministry of Energy and Mines has approved the PAMAs
related to Uchucchacua, Julcani, Orcopampa, Colquijirca, Ishihuinca, Huachocolpa, Shila and Paula, as well as the Environmental
Impact Study (EIA) of Antapite. As of December 31, 2005, the activities as defined in the PAMAs respective to the Uchucchacua,
Julcani, Orcopampa, Colquijirca and Ishihuinca mining units had been completed.
On October 14, 2003, the Congress issued the Law 28090 which regulates the procedures and commitments that the mining
activities must follow in order to elaborate, file and implement a mining site closing plan, as well as establishes the constitution
of a guarantee to assure the compliance of the committed plan in connection with protection, conservation and recuperation
of the environment standards.
On August 15, 2005 the corresponding ruling was approved. In accordance with the first regulation, the mining site closing
plans approved before the issuance of this ruling have to be adequate to the new disposals in a term no greater than nine
months since its publication.
During the year 2005 the Company made disbursements in connection with activities included in the mining site closing plans
by S/10,738,000 (S/5,691,000 and S/3,637,000 during the years 2004 and 2003). As of December 31, 2005, the Company has
recognized a liability of S/92,371,000 (S/67,521,000 as of December 31, 2004) related to its future obligations for the closing
of the mining units, see note 17(a).
On July 6, 2004, the Peruvian Congress enacted the Law N°28271 “Law that Regulates the Environmental Liabilities for the
Mining Activity”.This law has the purpose to regulate the identification of environmental liabilities of mining activities and the
financing to restore the affected areas. According to this law, an environmental liability corresponds to the impact caused to the
environment by mining activities, Buenaventura´s management is performing an inventory in areas currently abandoned or
inactive in which the company previously carried-out exploitation activities, in order to determine what activities are necessary.
In Buenaventura´s management opinion, the impact of these obligations is not significant for the 2005 financial statements.
(b) Land and mineral rights leases The Company has obtained the right to operate in certain areas through the execution of land lease contracts, as shown below:

Legal processes of Buenaventura Demand presented a the Federal Court at the United States of America –
Buenaventura and Condesa, together with Newmont Mining, Newmont Second and certain individual persons, were seeded in a legal
action in the Federal Court of the United Stated of America – Tenth Circuit (Colorado) with a French citizen that informed that he was
affected by the revocation of BRGM, Mine Or and their related entities (SCRCM) over preferential rights on the shares of CEDIMIN.
On March 16, 2005 all the involved parts reached to an extrajudicial agreement. As a consequence of this agreement, the
demand, pending of motion at the Federal Court of the United States of America - Tenth Circuit and subsequently dismissed by
the District Court, was filed definitively.
Other From time to time in the normal course of its activities, the Company is involved in various legal proceedings of a diverse nature.
Management believes that any possible loss, which may result from these lawsuits, will not have a materially adverse effect on
the Company’s financial position.
37. Transaction with affiliated companies
(a) The Company had the following transactions with its affiliated companies during the years ended December 31, 2003, 2004 and 2005:
S.M.R.L. Chaupiloma Dos de Cajamarca (“Chaupiloma”) Chaupiloma is the legal owner of the mineral rights on the mining concessions exploited by Yanacocha, and receives a 3 percent

the construction work finished in October 2001. Concurrently, Yanacocha and Conenhua signed a 10-year agreement covering
electric energy transmission and infrastructure operation beginning November 2001. In exchange for operating and managing
the transmission project, Yanacocha will pay an annual fee of US$3.7 million. During 2005, the revenues for these services
amounted to approximately S/12,813,000 in 2005 (S/14,282,000 and S/13,265,000 in 2003 and 2004, respectively).
The profit between Conenhua and Yanacocha is not significant and, therefore, has not been eliminated in the consolidated
financial statements.
