The Argentine branch of international environmental organization Greenpeace marked World Environment Day—a UN-sponsored event held each June 5—with a protest highlighting damage that the pro-mining policies of José Luis Gioja, governor of the northwestern province of San Juan, could have on Argentina's San Guillermo Biosphere Reserve. Eight Greenpeace activists climbed the Civic Center building in the city of San Juan and unfurled a 20-meter banner with a photograph of a puma and a caption reading: "Gioja: no mining in San Guillermo." The activists were arrested and taken to the central police station.

After more than  two weeks of tension, with a general strike by public-sector workers, roadblocks and episodes of violence, the Bolivian Workers' Central (COB) and the government of Evo Morales reached an accord May 21. Conflict around the strike, which began May 5, left at least 30 injured and more than 100 detained. COB demanded that the government double pensions, which currently range from $21 to $28 a month. COB called for reform of a pension law passed just three years ago, bringing pensions to the same level as monthly salaries, at least in the state mining sector. The government is now offering an 81% hike. The strike mostly affected the state-owned Huanuni tin mine in Oruro department—the country's largest, accounting for half the country's tin production—costing the government some $8 million. Mining is Bolivia's second foreign currency earner after natural gas. Silver is its largest metals export, followed by zinc and tin. (Mining Weekly, May 27; InfoBAE, May 22; AP, Reuters, May 17 May 16) 

National Police fired on protesters occupying the site of the Conga gold mining project in Peru's Cajamarca region on May 28, leaving one wounded in the leg and abdomen. Police, including elite troops from the Special Operations Divsion (DINOES), opened fire as some 1,500 campesinos were marching on El Perol laguna, to establish an encampement there. The Yanacocha mining company recently announced that it will begin pumping El Perol to divert the water into a reservoir and permit mining on the site—despite the fact that the project is officially suspended. A nearby reservoir dubbed Chaillhuagón has already been built, the company announced; the original laguna of that name is slated to become a pit-mine if the project moves ahead. The company says the new reservoirs will be made available for use by local residents, but Cajamarca's Unitary Struggle Command (CUL), which is coordinating the protests, pledges to resist any damage to the lagunas.

On May 24 Chile's environmental regulator, Juan Carlos Monckeberg, ordered a suspension of construction at the Toronto-based Barrick Gold Corporation's giant Pascua Lama mine because of violations of environmental laws. He also fined the company $16 million, the largest penalty Chile has ever imposed for an environmental violation. Monckeberg told the Reuters wire service on May 30 that the company would probably require one to two years to make the repairs that would allow it to resume construction.

Kyrgyzstan's President Almazbek Atambayev declared a state of emergency in Dzhety Ohuz district of the Issyk Kul region May 31, after hundreds of protesters at the town of Barskoon stormed the facilities of the Kumtor  gold mine, run by the Canadian-based Centerra Gold. Hundreds of villagers, some on horseback, blocked the road to the mine earlier in the week, to demand its nationalization, and more local social benefits. Villagers later seized a power substation and cut electricity to the mine. When security forces moved to clear the road, clashes erupted, with police using tear-gas and firearms; several protesters were injured and one reportedly killed. Some 80 have been arrested, and a curfew imposed across the district.

French Foreign Minister Laurent Fabius said May 28 during a stop in Niger that the attackers who carried out last week's double suicide bombings on a military camp and uranium mine likely came from southern Libya—indicating that jihadist forces driven from north Mali have taken refuge across borders in the lawless spaces of the Sahara. He also said they had inside help, saying: "The terrorist groups benefited from a certain level of complicity." Niger President Mahamadou Issoufou's also said the jihadists infiltrated from Libya. 

Just one week after imposing a 30-day state of siege on four municipalities in southeastern Guatemala that have been the site of violent confrontations over a Canadian-owned silver mine, President Otto Pérez Molina announced on May 9 that his government was lifting the measure and instead declaring a state of prevention in the area. Under the less severe state of prevention, "some rights remain limited," the president said, "such as the right to strike, and demonstrations when it's going to interfere with public services, [along with] the carrying of arms." Apparently, Pérez Molina had to back off from the May 2 state of siege because the National Congress had failed to approve it within three days, as required by law.

The Guatemalan government declared a state of emergency and banned public gatherings May 2 in four municipalities in the eastern highlands following clashes between police and anti-mining protesters.  The 30-day "state of siege" effects Jalapa and Mataquescuintla (Jalapa department), and Casillas and San Rafael las Flores (Santa Rosa department). (See map.) Constitutional guarantees are suspended, and the powers of local municipalities dissolved, placing them under the direct control of Pesident Otto Pérez Molina. Clashes between local residents and National Police and security guards this week left one officer dead, six residents wounded, and police cars burned near the Escobal silver mine at San Rafael las Flores. Protesters also briefly detained 23 police officers. The government says the protesters are armed with guns and explosives. The mine's owner, Vancouver-based Tahoe Resources Inc., said protesters armed with machetes "turned hostile" at the gate on on April 27, and security guards fired tear gas and rubber bullets, setting off days of angry protests.
