Some 30 protesters crashed the opening of the sixth Expominas trade fair at the Quito Exhibition Center April 3, where Ecuador's government sought to win new investors for the mineral and oil sectors. The protesters, mostly women, interrupted the event's inaugural speech with an alternative rendition of the song "Latinoamérica" by the Puerto Rican hip-hop outfit Calle 13, with lyrics referencing places in the country threatened by mining: "You cannot buy Intag, you cannot buy Mirador, you can't buy Kimsacocha, you can't buy my Ecuador." The activists wore t-shirts with the slogan: "Responsible mining, tall tale" (literally, cuento chino, Chinese tale). (Tegantai, April 3)

Authorities in northern China's Inner Mongolia Autonomous Region earlier this month blocked an attempted cross-country march by traditional Mongol herders, with police assaulting hundreds in two incidents. In the first incident, herders from Inner Mongolia’s Durbed (Chinese: Siziwang) banner (county) gathered at Hohhot train station on March 1, intending to march nearly 500 kilometers to Beijing. But police quickly arrived and broke up the gathering, according to the Southern Mongolian Human Rights Information Center (SMHRIC). The following day, troops in a dozen police vehicles descended on Halgait village in Zaruud (Zhalute) banner, breaking up another group that intended to march on Beijing. The herders hoped to arrive in Beijing for the meeting of the National People's Congress where Xi Jinping was installed as president, to protest confiscation of grazing lands.

Thousands of rescuers are struggling to reach 83 workers trapped by a landslide at a gold mine at Gyama, Maizhokunggar county, in China's Tibetan Autonomous Region March 29. The facility is operated by the Tibet Huatailong Mining Development Co, a subsidiary of the state-owned China National Gold Group Corp. Ironically, the Gyama mine was something of a showcase for Beijing's development of Tibet; the Huatailong company took it over in 2009 from some dozen small-scale private companies that operated on the margins of the law in what official news agency Xinhua called a "rat race for the rich ore supplies." The disaster prompted a flurry of criticisms on Chinese social media, but AP reports these were quickly "scrubbed off or blocked from public view by censors." 

Radio Espinar, the local transmitter in Espinar province of Peru's Cuzco region, issued a public protest charging that it was arbitrarily ordered closed by the Transport and Communications Ministry (MTC) March 18, charaterizing the move as "repression." The MTC said the decision not to renew the license was taken because the station had failed to pay an application fee and its equipment was found inadequate. But Matilde Taco Llave, daughter and legal representative of station owner Marcelino Taco Quispe, called the closure a disproportionate move, and said it was really motivated by the station's aggressive coverage of last year's local protests against the mineral operations of multinational Xstrata. "This is a consequence of having given information about what happened in the social conflict," she said. "We are sure that this is the cause."

Three campesino leaders from Tarqui village in Ecuador's southern highland province of Azuay began an eight-day jail term in the provincial capital Cuenca on March 21, convicted of having disrupted the local water supply during a May 2010 protest against the Quimsacocha mining project, run by Canadian multinational Iamgold. Residents say the Quimsacocha project (also rendered Kimsacocha) will degrade and deplete local water sources. Ironically, the jail term for the three leaders—Carlos Pérez Guartambel, Efraín Arpi and Federico Guzmán—began on the eve of World Water Day, March 22, when a march on Cuenca had already been planned to demand local water rights and oppose large-scale mining projects. The march, which brought out several hundred, began with a ceremony in support of the jailed leaders at Cuenca's judicial building. "This is called the criminalization of struggle," said Delfín Tenesaca, president of the highland indigenous alliance ECUARUNARI. (El Tiempo, Cuenca, Kaos en La Red, March 22; La Tarde, Cuenca, Ecuavisa, March 21)

Workers started a 72-hour strike at the Somina uranium mine in northern Niger March 20, demanding better wages and the release of unpaid bonuses. A spokesman for the Syntramines union told Reuters 680 workers have downed tools for the strike, which could be extended to an open-ended stoppage if demands were not met. Somina is run by the uranium unit of the China National Nuclear Corporation, Sino-U, in a partnership with Niger's government. The mine, in the remote Agadez region, was established in 2007, producing 700 tons annually. Niger is also top uranium supplier to France, which is expanding operations. Areva’s Imouraren mine is expected to more than double the French company's current production in Niger when it comes online in 2014, with expected output of 5,000 tons per year.

Authorities in Mexico's coal-producing northern state of Coahuila say that the notorious Zetas, bloodiest of the country's warring cartels, have taken over much of mining industry. Suspicions were first raised in October when top Zeta commander Heriberto Lazcano was found in a Coahuila coal mining town and killed in a shoot-out with Mexican marines. Coahuila produces some 95% of Mexico's coal at approximately 15 million tons a year, and current estimates place the Zetas' annual profits from their share of the industry at around $25 million. Former Coahuila governor Humberto Moreira said the Zetas are expanding their control over the state's mines, both legal and illegal. "They discover a mine, extract the coal, sell it at $30, pay the miners a miserable salary," he told Al Jazeera. "It's more lucrative than selling drugs."
