Found the following from May 2008.
I like the line "The Crow Nation has very substantial undeveloped mineral resources"

United States Senate Committee on Indian Affairs
Oversight Hearing on Indian Energy Development
"Regaining Self-Determination Over Reservation Resources"
May 1, 2008

The Crow Nation has developed a limited amount of its resources, typically with royalty (and some tax) revenue received as the lessor. Even though we had some oil and gas development between the 1920s and 1950s, most of our governmental revenue is derived from our 35-year relationship with Westmoreland Resources, Inc. Over that period, the Apsaalooke mine has produced about 150 millions tons of coal and is the largest private employer within the Crow Reservation.
The Crow Nation has very substantial undeveloped mineral resources. It is estimated that we own 3% of the world’s coal resource, exceeding 10 billion tons. We have been exploring our oil and gas reserves, and preliminary estimates believe them to be significant. In addition, we have large deposits of industrial minerals, such as limestone and bentonite. Finally, preliminary data suggests that we have class 5 / 6 wind energy as well as other renewable resources.
