The Trust's coal, oil and gas resources are principally located in the Southcentral and Interior Alaska, with over 100,000 acres currently under oil and gas lease in the Cook Inlet and Nenana basin regions and over 2000 acres under coal lease in the Healy and Sutton areas. The TLO regularly offers Trust land for oil and gas leasing and encourages active development of lands leased under this program. While increased coal lease acreage is unlikely on Trust lands, the Trust is encouraged by the possibility of production from Trust land coal leases.
