The present disclosure relates to a mining site comprising an extraction shaft passing through an ore body. Also included in the mining site are a lower shaft intersecting a path of the extraction shaft, a starting station extending from the lower shaft and from a bottom of the path of the extraction shaft, an arrival station overhanging above a top of the extraction shaft, and a upper shaft extending from the arrival station. In a particular aspect, the extraction shaft can be dug at a shallow angle between 10 and 45 degrees from horizontal. A shallow angle mining method for constructing the mining site is also provided. The present disclosure additionally introduces a hydro-electric site having a penstock dug at a shallow angle, and a method of digging a penstock.
