The giant Buenavista del Cobre copper mine in Cananea, near the US border in the northwestern state of Sonora, is in full operation again, a little more than three years after a police assault ended a 2007-2010 strike over health and safety conditions by Section 65 of the National Union of Mine and Metal Workers and the Like of the Mexican Republic (SNTMMSRM, "Los Mineros"). The mine produced earnings of $288.69 million for its owner, Grupo México (GM), in the second quarter of this year, according to an article in the left-leaning Mexican daily La Jornada. But the town itself hasn't prospered. The article reports that the past 10 years have brought an increase in "organized crime, unemployment, shortages of drinkable water, a growing incidence of different types of cancer and acute respiratory diseases, ecological deterioration, alcoholism, and, because of a large transient population, problems with housing and urban infrastructure."

An in-depth Sept. 29 Reuters report on the multi-billion-dollar but very murky jade trade in Burma raises the specter of "blood jade"—without actually using the phrase. Almost half of all jade exports are "unofficial"—apparently spirited over the border into China with little or no formal taxation, representing billions of dollars in lost revenues. Official statistics are said to indicate that Burma produced more than 43 million kilograms of jade in fiscal year 2011-12, worth a low-balled $4.3 billion. Yet official exports of jade that year stood at only $34 million. (It isn't explained how all that "unofficial" jade made it into the production stats in the first place.) China doesn't publicly report how much jade it imports from Burma, but jade is included in official imports of precious stones and metals, which in 2012 were worth $293 million—a figure too small to account for billions of dollars in Burmese jade.

The wife and infant son of a local mining leader were assassinated last week in the community of Pamputa, Coyllurqui district, Cotabambas province, Apurímac region, Peru. The bodies were found Sept. 18 by ​Carmelo Hanco, president of the local Artisenal Miners Association of Los Apus de Chunta, when he returned home from a trip to Abancay, the regional capital, where he had been petitioning authorities for the "formalization" of mining claims. Authorities said the killings took place during a robbery, but Hanco said he suspected the involvement of the Xstrata mining company—which he charged has been pressing for the arrest of independent artisenal miners in the region with an eye towards establishing its own operations. The company has for 10 years operated a giant gold, silver and copper mine at nearby Las Bambas (Chahuahuacho district), above the opposition of both local artisenal miners and campesinos. (Con Nuestro Peru, Sept. 21)

On Sept. 20, a group of workers and security guards from the Yanacocha mining company attacked the protest encampment established by local  campesinos at the Conga site, where the company seeks to expand operations of Peru's biggest open-pit gold mine. The tents and bivouacs were torn down and burned, and the protesters evicted from the site. Three days later, protesters returned to re-establish the encampment—some 500 strong, and headed by the movement's most visible leaders, Jorge Rimarachín, Gregorio Santos and Marco Arana. But that night, a group of some 10 men, hidden by darkness on the hills overlooking the new camp, fired shots at the protesters. A detachment of DINOES, the special anti-riot force of the National Police, looked on and did not interfere.

Some 20,000 Romanians marched and formed a human chain around the parliament building in Bucharest Sept. 21 to protest plans by Canadian firm Gabriel Resources to establish Europe's biggest open-pit gold mine at Rosia Montana in the Apuseni Mountains of Transylvania. Bucharest has seen daily protests against the  project for two weeks, organized by the campaign Salvati Rosia Montana, with thousands more taking to the streets in other Romanian cities. The protests began after the government proposed a law Aug. 27 to give extraordinary powers to Gabriel Resources' local partner, Rosia Montana Gold Corporation, allowing the company to relocate people whose homes are on the perimeter of the mine site, and guaranteeing all necessary permits within set deadlines, regardless of court rulings or public participation requirements. The operation would involve the destruction of three villages and four mountains. (EuroNews, Sept. 22; MondoNews.ro, Sept. 21; The Guardian, Mining.com, Sept. 17; BBC News, Sept. 9)

National Police troops in Peru's northern Cajamarca province on Sept. 17 clashed with residents of Quishuar Corral hamlet who were conducting reconassiance of mountain trails on their communal lands, which they suspected the Yanacocha mining company of illegally closing to facilitate expansion of its operations. Four of the villagers were injured, and two hospitalized. Witnesses said the police troops opened fire without warning with rubber bullets and tear-gas cannisters. (RPP, Sept. 17)

The National Indigenous Organization of Colombia (ONIC) released findings Sept. 13 that 62.7% of Colombia's indigenous population—a total of some 890,00 people—is at risk of extinction. Of the 102 indigenous communities in Colombia, 66 are found to be under grave threat, from forces such as large-scale mining development and the country's ongoing armed conflict. The findings follow a ruling issued by Colombia's Constitutional Court three days earlier that the government has not done enough to protect its indigenous population, after a 2004 decision by the same body ordered that additional measures be taken. The court held that efforts made over the previous decade to improve security for indigenous peoples have been ineffective and insufficient. The ruling found that indigenous communities are continuously victimized by armed groups forcing them off of their land, and endemic health problems caused by resource exploitation on their traditional territories. However, in contrast to ONIC, the court identified 36 indigenous groups at risk of extinciton.

Colombian campesinos on Sept. 10 ended their national strike after more than two weeks, and lifted the road blockades they were still maintaining, chiefly in Cauca, Nariño, Putumayo and elsewhere in the south of the country. The organization coordinating the strike in this region, the National Agricultural and Popular Table of Dialogue and Accord (MIA), agreed to recognize a pact already won in talks between the government and campesino organizations in Boyacá, Cundinamarca and elsewhere in the central region of the country. United Nations observers who had been brought in for the dialogue process confirmed that all protest roadblocks had been dismantled. (EFE, Sept. 11; El Tiempo, Bogotá, Sept. 7)
