  • The Centro de Minería Compatible is being built by the Zacatecas Mining Cluster. The facilities are under construction at the Parque Científico y Tecnológico Quantum in Zacatecas, a Complex that hosts enterprises and institutions focused in research and innovation.
  • The Mining Fund is to provide MX$41.96 M pesos (US$2 M) for 10 infrastructure projects in Minatitlan, Colima.
  • Government actions in Mexico generate uncertainty for mining enterprises. The elimination of the Mining Sub-Secretariat and the informal ban on the granting of mining concessions are the two more acute actions that send the wrong message to the mining industry. Another issue is constituted by the disputes between companies and the fiscal authority on taxation.

  • Graciela Marquez, Economy Secretary played down the high expectations for lithium production in Mexico. She pointed out that Mexico does not produce any lithium at all in the present, and that the strongly hyped Bacanora Lithium’s project in Sonora hosts a large deposit in clays, which makes its extraction expensive. Her comments were a response to the voices claiming for the nationalization of the lithium industry by a leftist congressional group.
