A former Cu-U occurrence/mine located in the NE¼ sec. 5, T30N, R4E, 0.8 km (0.5 mile) SSE of Horseshoe Mesa (coordinates of record) (Vishnu Temple 15 minute topo map), N of Grandview Point, South rim, Grand Canyon, on National Park Service land (Grand Canyon National Park). The Grand View Mine and (this) Last Chance Mine are the same (Mineralogy of Arizona, 3rd. ed.). Discovered 1890. First production was 1893 and the last was 1916.

The Grandview Mine officially closed in 1907 but went through a series of owners until William Randolph Hearst acquired the Grandview Mine. Hearst sold the property to the United States National Park Service in 1940 and it is now part of the Grand Canyon National Park. The Grandview Mine is now a roost for protected bat species including Townsend’s Big-eared Bat (Corynorthinus townsendii).

Mineralization is secondary Cu minerals with gangue species in a breccia zone along a monocline flexure in Shea basalt hosted in the Navajo sandstone. Redwall limestone is bleached, brecciated and marbleized. The Grandview monocline lies along the WNW-trending Cremation fault.

Serpukhovian - Early Cambrian
323.2 - 541 Ma

ID: 3026586
Mississippian, Devonian, and Cambrian sedimentary rocks

Age: Paleozoic (323.2 - 541 Ma)

Stratigraphic Name: Tapeats Sandstone; Bright Angel Shale; Muav Limestone; Temple Butte Formation; Redwall Limestone; Bolsa Quartzite; Abrigo Formation; Martin Formation; Escabrosa Limestone

Description: Brown to dark gray sandstone grades upward into green and gray shale, overlain by light to medium gray or tan limestone and dolostone. This unit includes the Tapeats Sandstone, Bright Angel Shale, Muav Limestone, Temple Butte Formation and Redwall Limestone in northern Arizona, and the Bolsa Quartzite, Abrigo Formation, Martin Formation, and Escabrosa Limestone in southern Arizona. These rocks record intermittent sea-level rise and inundation in early Paleozoic time. (330-540 Ma)

Lithology: Major:{sandstone,shale,limestone}, Minor:{dolostone,quartzite}
