and expanding mining projects since the 1950s, including new access, conveyance of ore and waste, drainage, exploration and water diversion. The use of TBMs for mining projects has not been without its fair share of challenges. Any simplified perception that TBMs cannot be used for mining projects is false, as it is subject to geological risk.

Geology and Economics of Strategic and Critical Minerals
An ore deposit is a well-defined mineral deposit that has been tested and found to be of sufficient size, grade, and accessibility to be extracted (i.e. mined) and processed at a profit at a specific time. Thus, the size and grade of an ore deposit changes as the economic conditions change. Ore refers to industrial minerals as well as metals.
