ASARCO: Ray Mine

Saturday, February 24, 2024 | 7:00 am – 3:30 pm | Ticketed Event

Transportation and lunch included. 

The site is not wheelchair accessible.

The Ray Mine ore body is a porphyry disseminated copper system, with secondary enrichment blanket and complex faulting geometries associated with region wide compressional and extensional tectonic environments. The Ray Operation consists of an open pit mine with concentrator, solvent extraction-electrowinning operation, maintenance, warehousing, and administrative facilities. The mine operates 24 hours per day/ 365 days per year, with an average daily production of 30,000 tons sulfide mill ore and 15,000 tons copper oxide leach. The copper concentrate and cathode products are shipped off-site to customers both domestic and international. Attendees of the field trip can expect to view diamond drill core at the core facility, see the mine site via the designated overlook area, engage in technical discussions with subject matter experts, collect representative ore samples if conditions permit, and gain a better geological understanding of the ASARCO Ray Mine.

The field trip is intended for geology, mining, metallurgy, and environmental professionals, who would like to see an operating copper mine in Arizona. ASARCO will provide subject matter experts to accompany the buses, to provide a geological overview, answer questions and be involved in technical discussions. The buses will visit the core shed and core storage facility, as well as the lookout area of the mine. Weather and mining permitting, the tour will extend to a copper sulfide or oxide outcrop area.

Freeport-McMoRan: Sierrita Mine – SOLD OUT

Thursday, February 29, 2024 | 7:30 am – 5:00 pm | Ticketed Event

Transportation, lunch, and guide pamphlet included. 

The Freeport-McMoRan Sierrita mine is an open-pit copper and molybdenum mining complex located about 20 miles southwest of Tucson. Originally developed as an underground copper mine in 1907, Sierrita converted to open-pit operations in 1959. The mine produces copper and molybdenum concentrate, cathode copper and rhenium, a rare and highly valued metal. The Sierrita operation includes a concentrator with a milling design capacity of 100,000 metric tons of ore per day, a run-of-mine oxide-leaching system and an electrowinning facility at Twin Buttes with a design capacity of 50 million pounds of copper per year. A hydrometallurgy process is used to upgrade, purify, and separate the ore into 99.99 percent pure copper. Sierrita also has molybdenum facilities consisting of a leaching circuit, two roasters and a packaging facility for processing concentrate.

Sierrita has one of the largest copper reserves in the U.S., and in the world, with estimated proven and probable reserves of 2,735 million tons as of December 31, 2022. The average ore grade is 0.22% copper and 0.02% molybdenum. Sierrita operations generated nearly $387 million in benefits for Arizona in 2021, including more than $250 million for Pima County.

On this field trip, you’ll spend time at the site overlook, the hydrometallurgy facility and the tailings facility.

What to Wear:
