The Bingham Canyon Mine (image center) is one of the largest open-pit mines in the world, measuring over 4 kilometers wide and 1,200 meters deep. Located about 30 kilometers southwest of Salt Lake City, Utah, the mine exploits a porphyry copper deposit, a geological structure formed by crystal-rich magma moving upwards through pre-existing rock layers. As the magma cools and crystallizes, it forms an igneous rock with large crystals embedded in a fine-grained matrix, known as a porphyry. Hot fluids circulate through the magma and surrounding rocks via fractures, depositing copper-bearing and other minerals in spatial patterns that a geologist recognizes as a potential porphyry copper deposit.
