COMMUNITY DISCOVERY CENTER VISION STATEMENT The ASARCO Mineral Discovery Center shall communicate the vital importance of the mining industry in our civilization, educate students and teachers in the earth sciences, and preserve part of the mining history of Arizona, and the Western United States.

ASARCO works side-by-side with hundreds of suppliers to meet the needs of the Mining Industry, and especially the needs of ASARCO customers. Now current and potential suppliers can get information on our purchasing policies and practices, learn how to increase their product portfolio within ASARCO, and can see first hand what is required to gain access to our mining sites. Our intention is for the Supplier Portal to evolve over time to be responsive to our Suppliers information needs.
