Snapshot	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 2023, access to the Cactus open pit - Phase III was launched, enabling the extension of the mine life to 2027. As part of the 2023 process, the disposal of the Carlota mine was not finalised. As at 31 December 2023, the Carlota mine remains in KGHM's portfolio, conducts regular operations and is currently not classified as an asset held for sale.

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.
