for reference Cerro Matoso - Colombia

The Cerro Matoso deposit in Colombia is located some 20 km to the south-west of the town of Montelibano in the Department of Cordoba on the western side of the Andes, and approximately 400 km north of the capital Bogota. It takes the form of a blanket on a 2500 m long oval shaped hill that rises some 200 m above the surrounding countryside. The ore is capped by a layer of lateritic soil that is usually overlain by a variable layer of ferruginous canga. The ore comprises a zone of saprolite and saprolitised peridotite. The footwall is un-weathered peridotite. In 1999 proven+probable reserves were more than 35 million tonnes at 2.3% Ni using a 1.5% Ni cut-off, and up to 60 mt at a 1% Ni cutoff. As such it is one of the highest grade lateritic nickel deposits in the world. The mine and ferro-nickel plant are operated by Cerro Matoso S.A., a subsidiary of the Billiton group.

Dear XiaoRan... I think you should ask a Columbian (private message is an option) about the details of that specific address. I don't think this is a language question that is suitable for English-English or any other language pair.
