thin deposit of minerals between definite boundaries; sometimes called “orebody”

Answer 3

Vein

Question 4

exposed part of the vein

Answer 4

Outcrop

Question 5

a horizontal or nearly horizontal passage driven from the surface for working or dewatering a mine

Answer 5

Adit

Question 6

the line of intersection between vein and the horizontal plane.

Answer 6

Question 7

angle of inclination of the vein from the horizontal plane

Answer 7

Dip

Question 8

a horizontal opening in or near a mineral deposit and parallel to the course of the vein or long dimension of the deposit

Answer 8

Drift

Question 9

underground “room” or working area from which ore is removed

Answer 9

Stope

Question 10

a vertical or inclined excavation in a mine extending downward from the surface or from some interior point as a principal opening

Answer 10

Shaft

Question 11

a horizontal opening/tunnel driven from the shaft to a vein

Winze

Question 16

the wall or rock under a vein or other steeply inclined mineral formation

Answer 16

Foot Wall

Question 17

the wall or rock on the upper side of steeply inclined deposits

Answer 17

Hanging Wall

Question 18

horizontal passage or drift which starts from shafts and are commonly spaced at regular intervals in depth; either numbered from the surface in regular order or are designated by their actual elevation below the top of the shaft; comprises lateral workings (stations, drifts and crosscuts)
