The absence of strategy in orepass planning, design, and management
prevalent geological structure, thus aggravating the situation.
Another example that demonstrates the costs of lack of
strategy is from a nickel mine, where the mine had no
alternative but to rehabilitate a critical orepass using a liner.
The actual costs of the rehabilitation orepass were close to
C$7 million.
