Resolution Copper (RCM) is a joint venture owned by Rio Tinto and BHP formed to develop and operate an underground copper mine near Superior, Arizona, U.S. The project targets a deep-seated porphyry copper deposit located under the now inactive Magma Mine. Rio Tinto has reported an inferred resource of 1.624 billion tonnes containing 1.47 percent copper and 0.037 percent molybdenum at depths exceeding 1,300 metres (0.81 mi). The proposed mine is one of the largest copper resources in North America. Following the passage of the 2015 National Defense Authorization Act, many Native American and conservation groups oppose the copper mine because it will destroy the area above Oak Flat and around the deposit.
Mount Toromocho is a mountain in the Junín Region, Peru that sits next to the long established mining camp of Morococha and hosts a large polymetallic metal deposit. Toromocho means in Spanish "a bull with no horns". It is now owned by the Aluminum Corporation of China (Chinalco), a parent company of Chinalco Mining Corporation International (CMC). Minera Chinalco Perú S.A., a subsidiary of CMC which operates the Toromocho mine, is boosting the mine's productivity with a new production line.
Southern Copper Corporation is a mining company that was founded in 1952. The current incarnation of Southern Copper can be traced to the 2005 acquisition of Southern Peru Copper Corporation by the Mexican copper producer Minera México.

The mineral industry of Peru has played an important role in the nation's history and been integral to the country's economic growth for several decades. The industry has also contributed to environmental degradation and environmental injustice; and is a source of environmental conflicts that shape public debate on good governance and development.
Mining in Ecuador was slow to develop in comparison to other Latin American countries, in spite of large mineral reserves. As late as 2012, according to the United Nations, Ecuador received less foreign direct investment per person than any other country in Latin America. During the 1980s, mining contributed only 0.7 percent to the Ecuadorian economy and employed around 7,000 people. Minerals were located in regions with little to no access, hindering exploration. Ecuador has reserves of gold, silver, copper, zinc, uranium, lead, sulfur, kaolin and limestone. The latter practically dominated the early industry as it was used in local cement plants.
Cerro Verde is a Peru-based mining company. Its activities include the extraction, exploitation and production of copper from the porphyry copper deposit located southeast of the city of Arequipa. In addition, the company holds a copper sale agreement with Sumitomo Metal Mining, as well as a molybdenum sale contract with Climax Molybdenum Company.
Minsur is a Peru-based mining company engaged in the extraction, foundation and refining of tin and copper. It is also involved in the exploration for new minerals deposits, with a focus on gold, silver, lead, and zinc ores.
The Toquepala mine is a large porphyry copper mine in the Tacna Province, Tacna Department, Peru. The mine is an open-pit mine producing copper, molybdenum, rhenium and silver with minor gold and zinc.
The Antamina mine in the Andes Mountains of Peru is one of the largest copper/zinc mines in the world. It is an open pit mine which had an estimated life of mine at 15 years. It also produced molybdenum. The mine is jointly owned by Teck Resources, BHP, Glencore, and Mitsubishi Corporation and independently operated by Compañía Minera Antamina S.A. It produced 390,800 tons of copper concentrate in 2006, 461,000 tons in 2013. The total capital expenditure of the mine by 2013 was US$2.3 billion. İt is located at an altitude of 4,300 meters above sea level.
The Olympic Dam mine is a large poly-metallic underground mine located in South Australia, 550 km (340 mi) NNW of Adelaide. It is the fourth largest copper deposit and the largest known single deposit of uranium in the world. Copper is the largest contributor to total revenue, accounting for approximately 70% of the mine's revenue, with the remaining 25% from uranium, and around 5% from silver and gold. BHP has owned and operated the mine since 2005. The mine was previously owned by Western Mining Corporation. Since the 1970s environmentalists, traditional owners and others have campaigned against the mine, largely on the basis of its contribution to the nuclear cycle and its use of underground water.
The Quellaveco mine is a large copper mine project located in the south of Peru in the Moquegua Region. It is undergoing government environment approvals for its Environmental Impact Assessment. The last EIA modification was submitted in 2014. The Quellaveco mining property is majority–owned by Anglo American. Quellaveco represents one of the largest copper reserves in Peru and in the world, having estimated reserves of 1.1 billion tonnes of ore grading 0.55% copper. The planned development of the mine estimates a processing capacity of 85000 metric tonnes per day. Fluor Corporation has been assigned as the EPCM contractor for this project.
The Cuajone mine is a large copper mine located in the south of Peru in Moquegua Region. Cuajone represents one of the largest copper reserve in Peru and in the world having estimated reserves of 1.6 billion tonnes of ore grading 0.57% copper.

Las Bambas copper mine is an open-pit copper mine in the Cotabambas province of Peru. With over a billion tons of copper ore, the deposit is one of the largest in the world and produces 2% of global copper. Las Bambas also produces molybdenum concentrates. Development began on the mine in August 2015 and production began in early 2016.
Tintaya is a Peruvian copper mine. It was owned by the Swiss corporation Xstrata. The mine is located in the Cusco Region, Espinar Province, Yauri District, southeast of Yauri. The ore processing rate is at 200,000 tonnes per year and the construction phase of the mine asked for US$1.5 billion investment. Bechtel was hired for feasibility and EPCM for the mine.
