Con 290 votos a favor, 186 en contra y una abstención, Morena y sus aliados en la Camara de Diputados madrugaron a la oposición y aprobaron en el pleno una iniciativa alterna a la del presidente Andrés Manuel López Obrador que reforma la Ley Minera y otros ordenamientos.

La propuesta -votada apenas en lo general y que se discute aún n lo particular, reduce de 50 a 30 años la vigencia de las concesiones mineras, con la posibilidad de prorrogarlas 25 años más y al término de ese plazo, en caso de participar en la nueva licitación del mismo lote, el titular tendría preferencia para otros 25 años improrrogables.

Con el rechazo de la oposición, el Pleno de la Cámara de Diputados arrancó el debate que terminó en la aprobación, en “fast track”, una nueva Ley de Minería, a iniciativa del grupo parlamentario de Morena.

“Se le da certeza al pueblo de México, se protege el medio ambiente y se cuida el agua”, sostuvo el diputado Ignacio Mier Velazco, coordinador del Grupo Parlamentario de Morena al defender que con la aprobación de esta iniciativa “ahora las concesiones ya no serán producto de acuerdos o de compadrazgos, si no se darán a través de licitación pública”.
