Deposit Type

  • Porphyry


Summary:

The Miami-Globe mining district in eastern Arizona is known for economically large-scale porphyry Cu, Au, and Mo deposits, such as the Miami-Inspiration and the Cu Resolution.

The area is built of igneous, metamorphic and sedimentary rocks of various ages from the early Proterozoic to the Tertiary.

The Carlota deposit is formed by the surface mineralization of copper oxides in the proterozoic Pinal Schist. Chrysocolla is a dominant ore mineral and usually occurs as coatings, crusts and filling in fractures and heavily desintegrated rock masses.


Mining Methods

  • Truck & Shovel / Loader


Summary:

Copper ore extraction by the Carlota mine is by conventional methods typical for open-pit metals mines, i.e. the ore is mined by blasting and then is transported by haulage trucks. In 2014 mining operations from the open pit ceased in the Carlota-Cactus Pit. In 2018 mining re-commenced in the Eder South area.
