LIMA, Feb 16 (Reuters) - Peru's top copper mines are starting to see activity hit harder by protests and blockades in the country's southern Andes, power data reviewed by Reuters shows, with Chinese-owned Las Bambas and Glencore PLC's Antapaccay currently worst affected. Those are MMG's (1208.HK) Las Bambas, Peru's third largest copper mine, and Glencore's (GLEN.L) Antapaccay, which have both been hit by blockades on a key mining corridor highway. The data backs this up, suggesting that mines are at times getting some supplies through the blockades, with Las Bambas in recent days see-sawing between full and half power use. Reuters GraphicsRepresentatives from Las Bambas, Antapaccay and Constancia were not immediately available to comment on whether they were receiving inputs for their operations or sending their concentrates in the two-day window with the blockades eased. "Anecdotal reports and high frequency data suggest that ongoing civil unrest in Peru is beginning to choke off activity at key copper mines.
