The Colombian Inspector General’s Office has called on President Juan Manuel Santos’ government to consider halting a Canadian firm’s open-pit mining project...[which] is unfeasible because it is located in the paramo – or Andean high-altitude – ecosystem of Santurban, Inspector General Alejandro Ordoñez said...The paramo areas “should be excluded” from Greystar Resources Ltd.’s mining project in keeping with legal requirements, Ordoñez said. The [firm] needs only to obtain an environmental license before it can begin developing the Angostura Mining Project...Environmentalists opposed to the mining project note that water sources in the Santurban supply Bucaramanga, Santander’s capital. The Committee for the Defense of Santurban’s Water Resources and Paramo have cited German Augusto Figueroa, former manager of the Metropolitan Aqueduct of Bucaramanga, as saying “the project represents a real threat to the city’s supply sources.”
