- The Grandview Mine, also known as the Last Chance Mine, was operated by Pete Berry from 1892 until 1901 in what later became Grand Canyon National Park. The Grandview Mine Historic District includes what remains of the mine workings and machinery as well as the ruins of a stone house and sleeping shanty. Physical evidence, including low stone walls and construction debris, suggests that several wood structures were also originally present on the site. Pete Berry established Last Chance Mine on Horseshoe Mesa in 1892. He constructed the four-mile Grandview Trail down to the copper mine, and in 1893 began hauling ore out by mule. Although the ore was over 70% pure copper and won a prize at the Columbian Exposition in Chicago, the mine did not prove profitable, and in 1901 Berry and his partners sold it to the Canyon Copper Company, who operated it until 1907. The mine was then acquired by William Randolph Hearst, who sold it to the National Park Service in 1940. The mineralization at the mine is secondary copper minerals in a breccia zone along a monocline flexure in the Redwall Limestone, which is bleached, brecciated and marbleized below the overlying Supai Group. Grandview is the type locality for , a copper aluminium silicate. Grandview produced exceptionally fine mineral specimens of cyanotrichite, brochantite, , and many other copper and uranium minerals. These specimens are now rare, as mineral collecting is not permitted in the National Park. In 2009, the mines were gated to protect bat roosts, support on-going bat research, preserve historic mine resources, and promote visitor safety. The gating project was done by Mine Gates, Inc., with support from Grand Canyon National Park, Bat Conservational International, and Freeport-McMoRan. Details of the mine site, as well as manufacturing and installation of each bat gate are documented on the MineGates site. (en)

- Grandview Mine är en tidigare koppargruva på Horseshoe Mesa vid i det område som senare blev Grand Canyon National Park i Arizona i USA. Den drevs under namnet Last Chance Mine av Peter D. Berry (1858–1932) mellan 1892 och 1901. Han anlade den 6,5 kilometer långa leden Grandview Trail från kanten på kanjon ner till gruvan och började 1893 lasta ut malm med mulåsnor. Malmen var rik på koppar, men gruvan blev inte lönsam. Peter Berry och hans partners sålde därför gruvan 1901 till Canyon Copper Company, som drev gruvan till 1907. Den nedlagda gruvan köptes 1913, tillsammans av det av Peter Berry och hans partners anlagda Grandview Hotel, av William Randolph Hearst. Hotellet drevs till 1916. Hearst sålde området till National Park Service 1940. Gruvorterna stängdes av med grindar 2009 för att skydda fladdermushålor, underlätta pågående fladdermusforskning samt bevara gruvan som byggnadsminne. Byggnadsminnet Grandview Mine består av en ruin av ett stenhus och ett bostadsbarack och rester av brytningsställen och gruvutrustning. (sv)
