Some 29 miners were trapped on Thursday after heavy rains provoked a landslide at the mine in the Bonanza project, about 260 miles (420 km) northeast of Managua, which was closed about four years ago after being deemed unsafe. Rescue teams will continue search efforts, after freeing two miners on Thursday and another 20 on Friday, according to Rosario Murillo Ortega, government spokesman and wife of Nicaraguan President Daniel Ortega. Artisanal mining is legal in Nicaragua, the poorest country in Latin America, where it is used as a way for more people to profit from the industry.
