The Tizapa Mine is a volcanic massive sulfide (VMS) deposit located in State of Mexico, Mexico. Dowa has a 39% ownership of the mine.

Commercial production of the mine began in 1994. After several expansions, annual production capacity reached approximately 950,000 tonnes. In 2023, the 29th anniversary of the Tizapa Mine, ore production reached 19 million tonnes. The mine produces zinc, lead and copper concentrates, producing approximately 80,000 tonnes, 40,000 tonnes and 5,000 tonnes, respectively.

The zinc concentrate yielded from Tizapa Mine is shipped to Akita Zinc, Dowa’s zinc smelter located in Akita, Japan. Zinc concentrate is an important raw material in Dowa’s smelting operations.
