This is a mineral economics question: Please provide a professional answer at high level

Imagine that a mining company is in feasibility stage, and 2 specific risks that could be effectively addressed with risk mitigants are listed below

1- Delays in permissions (Authorizations from both level of government could take longer than)

2- Project not accepted as presented (Major modifications requested from one or both government levels.)

Now, for each briefly describe the risk mitigant and explain how you believe it would address the specific risk.
