Mexican Network of People Affected by Mining (Spanish: Red Mexicana de Afectados por la Minería, REMA)[1] is a Mexican group that campaigns for political change and ecological conservation[2] and against open-pit mining.

The group is part of the Mesoamerican Movement Against the Mining Extractive Mode, known as M4.

[7] At the time, the group was protesting against Blackfire Exploration's work at its La Revancha mine.

[8] In 2022, the group was critical of the limitations of the nationalisation of Mexico's lithium, noting the reform did not take control of existing mines.

[9][10] The group predicted that Canadian and U.S. corporation would be the main beneficiaries of the reforms.
