Otuzco Copper Mining Corporation S.A.C. Hey Guys, I tried to reach the Tax ID (TAX REGISTRATION) of Otuzco Copper Mining Corporation S.A.C. in the Peruvian Tax Entity (SUNAT) Web site with no results. It seems that this company is not duly registered, nor have a Tax ID, which is neccesary to operate or exist. Is this company duly incorporated and entitled to sign any agreement? I tried to find any info about this company on Google with no results...Make your research...
