Protest Begins Against Billion-dollar Southern Copper Mining Project in Peru Reuters LIMA - Protesters blocked a portion of Peru's main coastal highway on Monday in the start of a new challenge to a billion-dollar copper mining project that has been a lightning rod for conflict. Protesters from the area bordering Southern Copper Corp.'s $1.4 billion Tia Maria copper mine project in the south of Peru carried signs and flags as they occupied a section of the highway, snarling traffic for cargo vehicles and others. The project has long been lamented by residents in the southern region of Arequipa where farmers say the mine will pollute their fields and affect water supplies. "We are not going to talk. We want the presence of President (Martin) Vizcarra with the cancellation of the project," Luis Cornejo, mayor of Cocachacra, told Reuters, referencing the construction permit granted by the government on July 9. .
