LIMA, June 22 (Reuters) - A community in Peru's Andes mountains on Wednesday blocked a highway used by MMG Ltd's Las Bambas copper mine, demanding payment for use of the road, according to a source close to the company and a protest leader.

The new conflict comes just two weeks after the mining firm resumed operations following another protest that forced Las Bambas to shut down for more than 50 days, the longest in the mine's history.

Residents in the Mara district of the Apurimac region blocked the highway with sticks and rubber tires, according to photos published on Twitter and confirmed to Reuters by a community leader.

"We are blocking (the road) because the government is delaying land appraisals on properties through which the road passes. It is an indefinite protest," Alex Roque, one of the Mara district's leaders, told Reuters.

A source close to Las Bambas also confirmed the blockade, but said it was not immediately clear if the protest was affecting transportation of copper concentrate from the mine.

Following the previous hiatus in operations, MMG said it expected production at the site and material transportation to resume on June 11.

Peru is the world's No. 2 copper producer and Chinese-owned Las Bambas is one of the world's largest producers of the red metal.

The protest and shutdown have caused a major problem for the leftist administration of President Pedro Castillo, who came to office last year pledging to redistribute mining wealth but who is also under pressure to grow the economy.

Las Bambas alone accounts for 1% of Peru's gross domestic product. (Reporting by Marco Aquino; Writing by Anthony Esposito; Editing by Sandra Maler)
