A limited number of residents (22) can sign up on the lobby clipboard for the free spring tour of ASARCO’s working open-pit Mission copper mine. The bus will depart from the clubhouse parking lot at 7:30 a.m. on April 30th. On your tour, you’ll see the tailing facilities adjacent to Rancho Resort as well as how copper ore is mined in the open-pit and then at the center you can see how it is processed in the mill to extract the copper minerals. The mine tour begins at the Mineral Discovery Center. There you can become familiar with the copper mining process in our exhibit center and video theater. Besides the free tour, there is no admission charge for the Mineral Discovery Center exhibits, Discovery Theater, or gift shop.
