for the fourth quarter 2011. All figures have been prepared in

Mr. Roque Benavides, Buenaventura′s Chief Executive Officer, stated:
'Net income in the fourth quarter reached US$230.9 million, which was
similar to the figure reported in 4Q10 (US$228.1 million). EBITDA from
Buenaventura′s Direct Operations was US$198.3 million, 15% lower than

Yanacocha and Cerro Verde decreased 9%, from US$457.0 million in 4Q10 to
US$415.6 million in 4Q11.
The lower gold, zinc and copper volume sold were offset by the increase
in silver volume sold, as well as higher precious metal prices.?

During 4Q11, net sales were US$385.0 million, similar to the US$382.3
million reported in 4Q10. This was explained by an increase in silver
volume sold, as well as higher gold and silver realized prices, which
offset lower gold volume sold.
Royalty income increased 20% from US$14.4 million reported in 4Q10 to
US$17.4 million in 4Q11 due to higher revenues at Yanacocha.

(*) Buenaventura Direct Operations
Accumulated net sales in 2011 were US$1,493.9 million, a 43% increase
compared to the same period in 2010 (US$1,047.9 million), while royalty
income was US$62.7 million, a 12% increase when compared to the US$55.9
million reported in 2010.
Buenaventura′s equity production1 in 4Q11 was 124,504 ounces
of gold, 6% lower than the 132,437 ounces reported in 4Q10 mainly due a
decrease in Orcopampa and Poracota production. Silver production in 4Q11
was 4.0 million ounces, a 16% increase when compared to the figure
reported in 4Q10 (3.5 million oz) due to higher production from
Uchucchacua and El Brocal.
Equity production1 in 2011 was 475,770 ounces of gold and
15.3 million ounces of silver. This represented a 4% increase in gold
production (458,765 ounces in 2010), and a 14% increase in silver
production compared to 2010 (13.5 million ounces).

the Chipmo mine in 4Q11 was 65,788 ounces, 17% lower than the 79,408
ounces reported in 4Q10 due to lower ore grade and a decrease in the
recovery rate (See Appendix 2). The old tailings treatment produced
5,508 gold ounces (compared to 5,857 ounces in 4Q10). As a consequence,
total gold production in 4Q11 was 71,296 ounces, 16% lower than the
85,265 ounces reported in 4Q10. Accumulated total gold production in
2011 was 285,201 ounces, an 11% decrease when compared to 2010 (319,694
ounces).
Cash operating cost in 4Q11 was US$472/oz, 30% higher when compared to
4Q10 (US$363/oz). This was mainly explained by:
?
?
?
?
1.
?
The 17% decrease in gold ounces produced due to a 16% decline in ore
grade
2.
An increase in supply expenses: reagents (cyanide) and diesel fuel
3.
Contractor costs increased approximately 70% due to the increase of
drilling (8% higher 4Q11 vs. 4Q10) and drifting work (29% higher
4Q11 vs. 4Q10), as well as a 50% increase in contractor prices.
4.
These factors were partially offset by an increase in the by-product
credit contribution explained by higher silver production and prices.
?
Gold cash cost in 2011 was US$454/oz, 28% higher than 2010 (US$356/oz).
At Poracota, gold production in 4Q11 was 11,089 ounces, a 24% decrease
when compared to 4Q10 (14,676 ounces) due to lower ore grade and a
decrease in the recovery rate (See Appendix 2). Accumulated gold
production in 2011 was 49,201 ounces, 18% lower than the figure reported
in 2010 (59,803 ounces). Cash operating cost was US$1,218/oz, 24% higher
than the figure reported in 4Q10 (US$983/oz), mainly explained by the
24% decrease in gold ounces produced.
Gold cash cost in 2011 was US$1,048/oz, 14% higher than 2010 (US$923/oz).

?
At Uchucchacua(100% owned by Buenaventura), total silver
production in 4Q11 was 2.8 million ounces, a 16% increase when compared

silver grade (See Appendix). Zinc production in 4Q11 was 2,047 MT, 26%
higher than the figure reported in 4Q10 (1,620 MT), while lead
production increased 6% (2,051 MT in 4Q11 vs. 1,930 MT in 4Q10). In

was 6,668 MT and lead production was 7,546 MT vs. 9.3 million ounces,
6,988 MT and 7,881 MT, respectively, in 2010.
Cash operating cost in 4Q11 was US$16.35/oz, a 14% increase compared to
US$14.28/oz in 4Q10. This increase was primarily due to higher
contractor expenses explained by a 25% increase in diamond drilling, as
well as 17% increase in contractor prices.

(US$12.65/oz).
At Antapite (100% owned by Buenaventura), total production in
4Q11 was 6,118 ounces of gold, a decrease of 37% compared to 4Q10 (9,777

compared to 2010 (35,803 oz).
Gold cash operating cost in 4Q11 was US$1,472/oz, 77% higher than in
4Q10 (US$830/oz), mainly explained by the aforementioned decrease in

ounces in 2010). Cash operating cost in 4Q11 was US$463/oz, 27% higher
than 4Q10 (US$364/oz) due to higher contractor and labor expenses,
partially offset by higher silver by-product contribution. Gold cash
cost in 2011 was US$367/oz, 8% higher than in 2010 (US$339/oz).
was 29,895 ounces of gold (11,958 ounces attributable to Buenaventura).

owned by Buenaventura) was devoted to treat copper ore.
Copper production in 4Q11 was 7,852 MT, 22% lower than 4Q10 (10,108 MT).
Copper cash cost in 4Q11 was US$4,135/MT, 46% higher when compared to
the US$2,836/MT reported in 4Q10 due to higher commercial deductions and
lower copper content in ore. Accumulated copper production in 2011 was
23,796 MT, 40% higher than 2010 (16,971 MT).
For 2011, total zinc production was 23,675 MT, a 33% decrease when
compared to the 35,340 MT reported in 2010. In the case of silver, total
production increased 16%, from 2,509,536 ounces in 2010 to 2,917,624
ounces in 2011. Lead production in 2011 was 9,504 MT, 18% lower than
2010 (11,583 MT).
Zinc cash cost in 2011 was a negative US$322 vs. US$994/MT in 2010. This
was due to a higher silver by-product contribution due to an increase in
silver production and prices.
General and administrative expenses in 4Q11 were US$16.3 million, 43%
lower than the figure reported in 4Q10 (US$28.5 million) due to a
reduction in the long-term compensation provision (US$6.0 million). For
2011, general and administrative expenses were US$75.2 million versus
US$98.2 million in FY 2010 (23% decrease).
Exploration costs at non-operational mining sites, which include care

million) and Mallay (US$4.8 million) projects.
Exploration costs at non-operational mining sites in 2011 were US$49.6
million, 37% higher than 2010 (US$36.1 million).
Operating income in 4Q11 was US$170.7 million, an 18% decrease compared
to the US$208.5 million reported in 4Q10. This decrease was mainly due
to the 20% increase in cost of operations, while revenues increased 1%.
Accumulated 2011 operating income was US$705.2 million versus US$417.0
million in 2010 (increase of 69%).
During 4Q11, Buenaventura′s share in associated companies was US$125.6

gold production in 2011 was 1.3 million ounces, 12% lower than 2010 (1.5
million).
Costs applicable to sales (CAS) at Yanacocha in 4Q11 were US$533/oz, 8%
lower than the figure reported in 4Q10 (US$577/oz) due lower operating
costs and higher silver by-product credits. CAS for 2011 was US$581/oz,
30% higher than 2010 (US$448/oz).

in 2011 was US$642.4 million, 9% higher than 2010 (US$589.9 million).
During 4Q11, EBITDA totaled US$362.0 million, a 50% increase compared to
4Q10 (US$241.7 million). This increase was mainly due to a 26% increase
in revenues (US$577.4 million in 4Q11 vs. US$459.9 million in 4Q10).

During 4Q11, Cerro Verde reported net income of US$202.6 million, a 46%
decrease when compared to US$374.9 million in 4Q10. This was mainly due
to a 28% decrease in sales revenues (US$565.0 million in 4Q11 versus

million, 2% higher than US$1,054.4 million in 2010.
