the outer limit of the pit, extremities of the feasible mining operation
Explanation:
The pit shell is the defined area where the mining is to take place. Imagine an irregular shape, and put it into the earth crust. The inside is the mining area, the outline is the shell. They establish the quality, position etc of the ore, and decide, how far the operation should proceed in any direction to make it worthwhile.
Nowadays it is a very sophisticated excercise, and here is a website to explain a "pit shell optimisation" computer program.
