| Underground mining entails sinking shafts to reach the target resource and driving tunnels and adits, either inclined or horizontally. |
| Our first target was in the vicinity of the Pinto mine and the Buckhorn mine, where a cluster of adits was indicated. |
| The Jomac mine's three adits lie within the Glen Canyon National Recreation Area boundary. |
| Many adits, shafts and tunnels, some extending over 100 m, pursue these veins deep underground. |
| Pits that run horizontally into a hill slope or cliff following material into the slope are known as adits or drift mines. |
| The orebodies were accessed through several adits and a few shallow shafts. |
