I have seen the report you refer to. That, has been "pumped" no end in an attempt to place "value" on the skull valley dirt. Please, for your edification I paste the Conclusion, to wit.
CONCLUSION
32 Lessees under state mineral leases have the right to mine
and extract valuable minerals from leased land during the term of
the lease. The relevant statutes and regulations, as well as the
Lease at issue, give Peeples this right. The criteria for approval
of general mining plans of operation do not give the Department
authority to reevaluate the mineral character of leases for
economic reasons. Accordingly, we reverse the judgment of the
superior court affirming the Department’s decision and remand this
case for entry of judgment in favor of Peeples.
Skull Valley has no Gold, or Platinum in amounts beyond "trace or crustial occurrences"
