What does the Golden Giant Mine and the  Lost McLeod Mine have in common?
Golden Giant Mine The Golden Giant Mine is a closed underground gold mine in the Hemlo mining camp in Canada, located north of Lake Superior, midway between Sault Ste. Marie and Thunder Bay, Ontario near the town of Manitouwadge.
San José Mine The San José Mine (Spanish: "Mina San José" ) is a small copper-gold mine located near Copiapó, Atacama Region, Chile. The mine became known internationally for its collapse in 2010, which trapped 33 miners 700 m underground. Its workings are reached by a long sloping roadway with many spiral turns (a diagram shows ten turns), not by a vertical mineshaft.
