Pascua-Lama is an open pit mining project of gold, silver, copper and other minerals. Pascua Lama is located in the Andes mountains, in the southern reaches of Atacama Desert, straddling the border between Chile and Argentina at an altitude of over 4,500 metres. Toronto-based Barrick Gold, the world's largest gold mining company, is developing the project. Due to its proximity to glaciers, Pascua-Lama has caused controversy and public protest in Chile, including demonstrations and petitions presented to the Chilean government. Chile has not approved the project.
Legal background 
There is a long-running Court action (Action No. C-1912-2001) in Chile found on the Court's website, initiated in 2001 by a professional mining agent, one Mr. Villar, regarding mining rights for a 3,100-hectare plot of land in Chile next to Barrick's Pascua Lama mine. The lone road to Barrick's Pascua Lama mine snakes through Mr. Villar's claim, however even if Barrick doesn't win the appeal against Mr. Villar, Barrick can still continue to use this road to as Mr. Villar would only control mining rights to the disputed territory, not surface rights. The Court case is now moving to a final conclusion at the Supreme Court level in Santiago's 14th District Court. [Chile is a "Napoleonic Code" jurisdiction, similar to France and Quebec, and its system of law varies from that in England, Canada and the United States ("Common law" jurisdictions). Accordingly, its Court procedure is considerably different than that of Common law jurisdictions.]
The project formerly became possible with the adoption by Chile and Argentina of the Mining Integration and Complementation Treaty, signed by the presidents of Chile and Argentina in 1997 and ratified by their legislatures in 2000. This treaty permits investors to explore and exploit mineral deposits that straddle the border between the two countries. In 2000, an appeal was filed with the Chilean Constitutional Court to rule the treaty unconstitutional. Alcayaga, Luna, and Padilla, analyzing the treaty, have concluded that, "both in terms of content and form, [it] contains provisions that violate Chile's constitution". Nevertheless, nothing came of the lawsuit, and Chile's National Environmental Commission (CONAMA) issued its final approval for the Pascua Lama project on 13 June 2006.
History of the project 
The mining project is organized by the Barrick Gold corporation, which planned in 2006 to invest US$1.5 billion over 20 years in it and projects an annual output of 750,000 ounces of gold and 30 million ounces of silver in the first five years.
Barrick has been planning the project for several years. It performed its first studies of the glaciers in 1991, purchased the Chañarcillo estate at the location via an affiliate (Empresa Nevada) in 1997, and published an environmental impact report in 2000, which was approved by COREMA, the regional environment authority, in 2001.
Barrick's plans for the project have changed over time. In June 2005, Barrick intended to commence building in January 2006, after responding to a questionnaire put to it by CONAMA, Chile's National Environmental Commission. In November 2005, however, the company published a report stating that it had scrapped its original plans, presented in December 2004, for "transplanting" three glaciers in order to gain access to the deposits beneath them, moving them to another glacier with which they were to bond. This change was publicly supported by Fernando González, the chairman of the council of Huasco Valley farmers.
In 2012, in the context of the costs of water usage in mining globally, Barrick's escalating costs for the Pascua Lama mine were reviewed. "As of November 1, 2012, Barrick had spent $3.7 billion on Pascua Lama. In all, it plans to invest between $8 and $8.5 billion to bring the project into production. But if the past is any guide, those costs could rise: the company's budget was just $3 billion in 2009".
Environmental consequences controversy 
Those protesting the project contend that it will involve the removal of 20 hectares of ice, a volume of 300,000 to 800,000 cubic metres, and that this will cause serious environmental harm. Nevertheless, the EIA and IIA approvals in both Chile and Argentina specifically preclude this from happening, and Barrick has confirmed it has no plans to move any ice or glaciers. To do so would be a violation of the permits granted by the relevant authorities. Opponents also contend that the project will affect the water supply of the 70,000 farmers in the Huasco valley, releasing cyanide, sulfuric acid (vitriol) and mercury into the valley's rivers, that the company has bought the support of the farmers with "social assistance" and promises of US$60 million for infrastructure work, and that the Mining Integration and Complementation Treaty was adopted under pressure from Barrick. In November 2005, a petition of 18,000 signatures was presented to the Chilean government by the Anti Pascua Lama Front, a coalition of environmentalist groups.
The original scope of the ore body lay partially under two small glaciers which eventually feed into the rivers of the Huasco Province. Environmental reviews took place over more than two years and government authorities imposed 400 conditions on the company in order to mine. As a consequence, more than one million ounces of gold at the site will not be mined. However controversy is still rampant as to the real environmental impact, as mine exploration has already been linked to a 56 to 70% depletion in the three glaciers nearest to the mine site.
Extensive water management infrastructure is incorporated into the mine design to mitigate the effects of surface and sub-surface water migration across the operation.
The historical record of these types of projects in Chile and the companies' real-world ability to meet legal environmental constraints makes the processing of residual-waste a point of contention. The inability or unwillingness of local authorities to stand up to spills and breaches of environmental requirements is well known and another key point of disagreement with opponents to the project.
The recent approval (as of 2000-2009, during the Lagos and Bachelet presidencies  ) of many controversial projects such as large mines, dams for power generation, huge salmon farms, forestry, etc. in spite of many legal and environmental concerns, again question the ability or willingness of the Chilean Government to address local communities concerns' when clashing with large corporations and perceived economic benefits.
These issues have recently even been criticized by the OECD as major impediments for Chile being able to join the 'elite club' of developed countries.
Barrick Gold contends that the project is environmentally friendly in terms of water treatment, and that the project will create 5,500 direct jobs during the mine's construction phase. It contends that underground mining methods are not economically feasible for the mine, only open pit methods. It states that its US$1.5 billion investment "would be directly invested in the Huasco province in Chile and San Juan province in Argentina", that it has "identified more than 600 potential suppliers from Chile’s Region III" in pursuance of its policy of sourcing local goods and services, and that "sustainable development projects have been and will continue to be a priority for funding to the tune of millions of dollars focused in the areas of education, health, infrastructure and agricultural improvement".
Electronic mail chain letter 
This project was in 2006 the subject of an online petition, circulating as a chain letter by electronic mail, imploring the Chilean government to prevent the project from obtaining authorization because of the environmental and social consequences of the mining operation. According to analysis by Snopes, the main point of the petition was valid, but it did contain some misleading passages. Barrick published a response countering many of the statements made in the chain letter.
