Minera San Jorge and Cia. Minera Cinco Minas were in the past holders of mining concessions, now former employees fight the titles. One of them signed a rights assignment contract with Grupo Zafermex hoping that the trial will be resolved favorably, the trial is not over yet and Gogold promotes being the holder of the concessions and earns millions. The Public Mining Registry does not recognize Grupo Zafermex or Gogold as holders. IT'S A FRAUD.
