Marco Antonio Corrales has given up on the peanut and alfalfa crops he was growing this season along the banks of the Sonora River in northern Mexico. That’s because the waterway, polluted by a copper sulfate solution that spilled from Grupo Mexico SAB (GMEXICOB)’s Buenavista del Cobre mine last month, then overflowed after Hurricane Odile soaked the region, flooding Corrales’s fields. “We have to assume we’ve lost everything,” said the 46-year-old grower, sporting a cowboy hat and a chunky silver belt buckle. “The Sonora River was our livelihood.” The combination of Mexico’s largest mining spill and heavy rains swelling the chemical-tainted river are causing losses to almost all cattle ranchers and crop damage in an area the government says accounts for nearly 20 percent of the state economy. Sonora’s worst rainy season in 40 years also sparked officials, who shuttered one-fifth of the mine’s production, to reduce levels at all containment pools, deputy environmental prosecutor Arturo Rodriguez said.

Japanese trading house Mitsui & Co Ltd (8031.T) said it had sold its 25 percent stake in Silver Bell Mining to a unit of Grupo Mexico (GMEXICOB.MX) that already owns the remaining 75 percent in the operator of Silver Bell copper mine in Arizona. The sale comes as part of Mitsui’s three-year business plan, mapped out in May, to sell off 700-900 billion yen ($6.4-8.2 billion) of assets by March 2017 to fund investment plans and seek returns to shareholders. “After examining our global assets, we’ve decided to sell some assets which are not among our top priority list,” a Mitsui spokesman said on Thursday.

Mexican federal officials say Grupo Mexico, a mining conglomerate, will set up a $151 million trust to pay for damage caused when one of its mines spilled acid-laced copper sulfate and heavy metals into two rivers in northern Mexico on Aug. 7. The company blamed heavy rains for the overflow of containment ponds on Aug. 7. Officials say lax supervision at the mine appeared to have caused the accident.

“This is the worst natural disaster provoked by the mining industry in the modern history of Mexico,” said Mexican Environment Minister Juan José Guerra Abud on Tuesday.
