MEXICO CITY, April 10 (Reuters) - Mexican President

Claudia Sheinbaum said on Thursday that her team was seeking to

resolve issues which had led to strikes at three mines,

including a large copper mine in the Cananea region in the

northern state of Sonora.

These strikes were long-running, Sheinbaum said in her

regular morning press conference, adding that the working

conditions of miners needed to be improved and the environment

protected.

The Buenavista del Cobre mine in Cananea is operated by

Grupo Mexico and has been closed for some time.

Sheinbaum did not name the other two mines.
