Ask the proponent to: 1. Provide a list of all mining companies who performed any form of due diligence under Confidentiality Agreement or "informal" review/due diligence and why they terminated the Agreement/interest or showed no further interest in pursuing an Agreement/interest. They are a publically traded company.
2. Provide a statement that the existing "small" mine plan will and can produce proven/probable mineral "ore" reserves per a Feasibility Study.
3. Provide a statement that underground mining only is economically infeasible.
After 22-years and $1 billion spent with an existing mine plan this should not be an issue.
Easy.
