At least 800 members of Section 65 of the National Union of Mine and Metal Workers and the Like of the Mexican Republic (SNTMMSRM, "Los Mineros") began blocking the three main entrances to the giant Buenavista del Cobre copper mine in Cananea, near the US border in the northwestern state of Sonora, on Aug. 20 to protest environmental damage caused two weeks earlier when about 40,000 cubic meters of copper sulfate acid solution spilled from the mine into the Bacanuchi and Sonora rivers. Most of the unionists lost their jobs four years ago when the mine's owner, Grupo México S.A.B. de C.V., broke a 2007-2010 strike over health and safety issues. "During the strike we made several complaints about the improper and inadequate measures Grupo México implemented for preventing overflows from the dams" for chemicals and heavy metals, Section 65 director Sergio Tolano Lizárraga told the national daily La Jornada. He said the blockade would continue until the company recognized the workers' old contract. (LJ, Aug. 22)

Authorities on Aug. 10 imposed restrictions on the water supply to seven municipalities in northwest Mexico's Sonora state, after 40,000 cubic meters (10 million gallons) of toxic leached copper from the Buenavista del Cobre mine turned the Río Bacanuchi orange, killing fish and livestock. Among the towns cut off by order of the National Water Commission (Conagua) is the state capital, Hermosillo, home to nearly 800,000 people. The Bacanuchi is a tributary of the Río Sonora, the state's principal river. Sonora state civil defense director Carlos Arias accused mine owner Grupo México of not reporting the spill in a timely manner.

The Penal Court of Celendín, in Peru's Cajamarca region, sentenced three members of the Chaupe family—Jaime Chaupe, Máxima Acuña, Elías Chávez and Isidora Chaupe—to two years and eight months in prison for the crime of land usurpation against the Yanacocha mineral company. The contested land, in Sorochuco district, Celendín province, is located in the influence zone of the contested Conga mega-mine project. The sentence may be suspended, but the defendants were also fined 5,000 soles, approximately $2,000. Yanacocha's lawyers argued that the presence of a company road through the disputed 30-hectare plot indicated the company's prior ownership of it. Mirtha Vásquez, counsel for the Chaupe family, countered that the company had never legally registered its ownership of the plot since purportedly purchasing it in 1996.

At a July 25 meeting in Port-au-Prince, some 28 Haitian organizations expressed their interest in joining a movement to oppose plans under way for open-pit mining in the north of the country, with a focus on gold mining operations by the Vancouver-based Eurasian Minerals company. The meeting was organized by the Collective Against Mining, which was formed a year ago by Tèt Kole Ti Peyizan Ayisyen ("Small Haitian Peasants Unity"), the Defenders of the Oppressed (DOP), the Popular Democratic Movement (MODEP), the Haitian Platform of Human Rights Organizations (POHDH), the Haitian Platform Advocating an Alternative Development (PAPDA) and Batay Ouvriye ("Workers' Struggle").

Davi Kopenawa, traditional shaman and internationally renowned spokesman for the Yanomami people in Brazil's Amazon rainforest, has demanded urgent police protection following a series of death threats by armed thugs reportedly hired by gold-miners operating illegally on Yanomami land in Roraima state. In June, armed men on motorbikes raided the Boa Vista office of Brazil's non-governmental Socio-Environmental Institute (ISA), which works closely with the Yanomami, asking for Davi. The men threatened ISA staff with guns and stole computers and other equipment. After the assault, one of the men was arrested, and reportedly told police that he had been hired by gold-miners. In May, Yanomami Association Hutukara, headed by Davi, received a message from gold-miners saying that Davi would not be alive by the end of the year.

Some dozen National Police troops on July 9 attacked the community of El Lirio in Celendín province of Peru's Cajamarca region—the scene of ongoing protests over the pending Conga gold-mining project. The attack came after El Lirio's comuneros blocked vehicles from the Yanacocha mining company that attempted to enter their lands. Police troops used tear-gas to break up the blockades, and Milton Sánchez, leader of the Celendín Interinstitutional Platform, said the community's children were among those affected. One woman was seriously hurt in the attack, he said. The vehicles were reportedly attempting to bring "gifts" to the local communities, but were backed up by an escort of police troops. (Servindi, July 9)

Brazilian federal judge Claudio Henrique de Pina has revoked Toronto-based Belo Sun Mining Corp.'s environmental license for the construction of the $750 million Volta Grande open-pit gold mine near the Xingu river in the northern state of Pará, the federal Public Ministry office in the state announced June 25. Upholding a suspension ordered last November, the judge ruled that Belo Sun had failed to address "negative and irreversible" impacts the mine would have on three indigenous groups in the area, the Paquiçamba, Arara da Volta Grande and Ituna/Itatá. The communities are already under threat from the construction of the Belo Monte dam, which will cut water flows by 80% to 90% when it goes into operation, according to the government's National Indigenous Foundation (FUNAI).

Workers from the Sepecol private security firm blocked the rail line leading from the mammoth Cerrejón coal mine in northeastern Colombia's La Guajira region for seven days over a contract dispute, before the company agreed to enter a dialogue over their demands June 26. The workers, who are mainly from the indigenous Wayuu group, launched their protest after the termination of the contract between Sepecol and Colombia's largest coal mining company. According to a company statement, the blockade of the rail line linking the mine to Puerto Bolívar was putting export obligations at risk. In announcing the dialogue, the company agreed to maintain 80% of its 770-strong security force from Sepecol and local firm Vigilancia Guajira.
