Our Company

Antamina is a polymetallic mining complex that produces copper, zinc and

molybdenum concentrates, and silver and

lead concentrates as by products. The mine is located in the district of San

Marcos, Ancash Region, 200 km. from the city of Huaraz at an average altitude of

4,300 meters above sea level. The

company has its own port, called Punta Lobitos located in the coastal province of

Huarmey. Investment in Antamina (an initial

investment of approximately U.S. $ 2.3 billion, plus U.S. $ 1.2 billion of investment

in the expansion of its operations) is

considered the highest in the history of Peruvian mining. Today it is among the

largest Peruvian producers of copper and zinc concentrates and one of the ten largest

mines in the world in terms of operating

volume. Compania Minera Antamina SA is a

company incorporated under Peruvian law, the product of a joint venture between four

leading companies in the world mining

industry. Antamina's shareholders are:

• BHP Billiton (33.75%) • Xstrata (33.75%)

• Teck (22.5%) • Mitsubishi Corporation (10%)

Antamina has four areas of operations:

The Mine The mine is located in the Antamina Ravine,

in the district of San Marcos, at latitude 9 º

32’S and longitude 77 ° 03’W and has a current estimated useful life until 2029.

This is an open pit operation that works with a skarn type deposit.

A daily average of 430,000 tons of material

is extracted and with operating running 24

hours a day, 365 days a year, 12-hour shifts, making it one of the ten largest

mining operations in terms of volume. The mine pit currently measured 3.400 meters

long and 1.800 meters wide and has a

depth of 700 meters. The total proven and probable reserves amount to 745 million

metric tons.

Camp Yanacancha Located at this camp is the Concentrator

Plant, which may be considered one of the

most automated existing plants in the

world, equipped with a technology that can directly process the ore that is extracted

from the pit. The camp also has modern and comfortable lodging accommodations

for all personnel.

Punta Lobitos Port

The port is located in Huarmey, 290 kilometers north of Lima. This facility

receives the ore concentrates that are transported from the mine through a

modern steel ore pipeline, coated with

HDPE, over a distance of 302 kilometers. The concentrates, which come in the form

of a slurry pulp –containing 65% solids, are received, filtered, stored and loaded onto

ships for export. The surplus water from

this ore concentrate is treated and then used in the afforestation of a 170 hectare

wooded forest. The port has ISO 14001 and ISO 9001 Certification.

Tailings Dam

Located in the Huincush Ravine at 4,075

meters above sea level, this tailings dam is believed to be the highest in the world. Its

huge size, owing to its storage capacity of up to 550 million tons of tailings, and

structural leak-proof design, ensure strict

environmental care.

Antamina in history

The Quechua word "anta" means copper giving rise to "Antamina” or copper mine.

The ancient Peruvians knew the properties

of this mineral and extracted it just like other metals.

Around the year 1860, the Italian-Peruvian intellectual Antonio Raimondi travelled to

the province of Huari and visited the

Antamina mining site, documenting its properties in his masterpiece book "Peru."

The site was forgotten for decades, and it was not until 1952 that Antamina was

added to the mining project portfolio of the Cerro de Pasco Mining Company.

The military government of Peru in power

in 1970 took over the property. However, unstable political conditions the investment

became unfeasible. Starting in 1973, Minero Peru administered the Antamina

deposit and conducted joint studies with

the Romanian firm GEOMIN that explored it for 15 years, totaling only 12 km of

diamond drilling. Total reserves of 120 million metric tons were estimated for a

plant that could process 25,000 metric tons

per day. In 1996, after a privatization process, the

mine deposit was acquired by Canadian mining companies Rio Algom and Inmet,

who, following an intensive exploration period of only 11 months, accumulated a

total of 118 km of diamond drilling, this

time calculating its reserves at 500 million tons. Then they increased treatment

capacity to 70,000 metric tons per day. The investors who won the tender bid

formed Compañía Minera Antamina S.A.

After a two year process of exploration and three years to build its mining complex, the

company began trial operations on May 28, 2001. Five months later, on October 1st of

that year, Antamina began commercial operations in the production of copper and

zinc concentrates and other products.

The official inaugural ceremony was held on November 14th 2001, with the presence of

then President Alejandro Toledo Manrique.
