A New York Times reporter followed a a force of Peruvian marines and rangers in a raid against illegal gold-miners in the Tambopata Nature Reserve, in the country's southern Amazon. Upon finding mining camps along the Río Malinowski, troops slashed bags of rice and plastic barrels of drinking water before setting everything on fire. But, massively outnumbered by perhaps 10,000 illegal miners in the area, they seem to be fighting a losing battle. They soon ran out of dynamite and resorted to a less sophisticated tactic: using mallets to smash the truck engines that miners use to power their derricks.

Amid moves toward peace in Colombia, the goad of the war—the country's lucrative cocaine trade—clearly remains robust. In an international operation announced June 30, Colombian police joined with US and Italian authorities to confiscate a whopping 11 tons of cocaine in refrigerated containers ostensibly shipping tropical fruits to Europe. The stuff was mostly seized in Colombia, but was bound for the US and Europe. Of the 33 arrested in the operation, 22 were popped in Colombia and the rest in Italy. (El Tiempo, June 30)

Colombia's Constitutional Court on June 11 overturned a government decree from 2012 that would allow mining in nine areas of the country, together making up 20% of the national territory—a collective area approximately the size of Minnesota. The designated "Strategic Mining Areas" were decalred by the National Mining Agency in decrees 180241 and 0045 of February and June 2012, respectively, affecting lands in some 20 departments, from the Pacific coast to the interior Amazon. The challenge was brought by the NGO Tierra Digna on behalf of several indigenous and campesino groups within these areas, who said to the decrees violated their right to prior consultation. The ruling virtually ends the government's declared ambition to make mining the “motor” of the Colombian economy. (El Tiempo, June 13; Colombia Reports, June 12; El Espectador, June 11)

Peru's president-elect Pedro Pablo Kuczynski has unveiled a platform that calls for privatizing and "individualizing" communal lands to facilitate mineral and agribusiness development. On June 10, PPK's "virtual" minister for Economy and Finance, Alfredo Thorne, told Lima's Radio Capital: "A big part of the properties where the mines are located are today communal property. These properties must be individualized, to give the individual the power to use his land, or to sell it to a mining company or sell it for agriculture." He said he is already working on a map of Peru's properties, to begin "interchanging communal titles to individual titles."

Campesinos launched a strike across Colombia May 31, with some 100,000 blocking highways and effectively shutting down at least half of the country's 32 departments. One is reported dead from clashes at a roadblock outside the main Pacific port of Buenaventura, and four soliders were briefly detained by protesters on the Quibdó-Medellín highway. The "indefinite" strike, or National Agrarian Minga, was called to protest the economic policies of President Juan Manuel Santos, and especially to press him on promises made in 2013 to end a similar national strike that left dozens dead. "They have not complied with 30% of the accords," said Robert Daza of the Agrarian Summit. He charged Santos with drawing up a National Development Plan that corresponds to the needs of the Free Trade Agreement with Washington rather than Colombia's small producers. Daza said Santos is "putting the strategic resources of the nation up for sale [and] distributing the land in an unequal manner."

As Venezuela lurches deeper into political crisis, President Nicolas Maduro has announced a new phase in the government's controversial "Operation Liberate the People" security program, pledging to cleanse the country of gang-related crime. Thousands of elite military troops have been deployed across Caracas, with five new "permanent" bases and over 130 checkpoints established in the city. Perhaps not coincidentally, this comes as Maduro has declared a "state of emergency" throughout the country in response to a supposed US-backed conspiracy against him by the political opposition, earning rebukes from Amnesty International, which called the declaration "alarming."

On May 25, Argentina's Revolution Day, some 20 townspeople in Jáchal, San Juan province, held a "patriotic march" to oppose the local operations of Barrick Gold—only to be surrounded and arrested by the police. Organizers said the march was peaceful, but the town's mayor, Miguel Vega, said that he was illegally detained and assaulted by protesters. The town saw a recent controversy, when the municipal council, with Vega's support, voted down a measure to hold a popular consulta or referndum on the mine's operations. (InfoBae, Diario La Provincia, May 26; Diario de Cuyo, May 19) Meanwhile, operators of Argentina's biggest open-pit mine at Bajo de la Alumbrera, Catamarca province, also the site of repeated protest campaigns, announced that the facility will be closing next year, its lode of gold and copper nearly exhasuted.

Peru's President Ollanta Humala declared a 60-day state of emergency in the rainforest region of Madre de Dios in response to reports of mercury poisoning by outlaw gold-mining operations. According to country's Environment Ministry, as many as 50,000 people or 41% of the population of Madre de Dios, have been exposed to mercury contamination. The government plans to send hospital ships and loads of untainted fish to the area, where mercury has contaminated local waterways. Illegal gold production has increased five-fold in Peru since 2012, and it is estimated to provide 100,000 direct jobs in the country, 40% of which are in Madre de Dios. Peru is the world's sixth largest gold producer, but an estimated 20% of its annual output is of unknown origin. (Mining.com, La República, May 24)
