A mineral survey of the Charles M. Russell Wildlife Refuge in Montana indicates that parts of the area have demonstrated resources of low-rank coal and bentonite in areas of substantiated potential and all of the area is assigned a probable resource potential for oil and gas because it is underlain by sedimentary strata known to contain hydrocarbons in other areas. Potential hydrocarbon accumulations, including both oil and gas, are difficult to delineate because of the absence of subsurface control points within the refuge. Geophysical surveys and directional drilling along the fringes of the wildlife refuge would aid in refining resource estimates for organic fuels. 1 ref.

A geologic, geochemical, and geophysical investigation and a survey of mines, prospects, and quarries were conducted to evaluate the mineral-resource potential of the Wild Rogue Wilderness, Oregon. Approximately 800 mining claims, one-third of which are placer gold locations, exist in or adjacent to the area. The Wild Rogue Wilderness has one area of probable resource for copper, lead, zinc, silver, and gold and two area of probable resource potential for gold.

Under the provisions of the Wilderness Act (Public Law 88-577, September 3, 1964) and the Joint conference Report on Senate Bill 4, 88th Congress, the U.S. Geological Survey and the U.S. Bureau of Mines have been conducting mineral surveys of wilderness and primitive areas. Areas officially designated as "wilderness," wild," or "canoe" when the act was passed were incorporated into the National Wilderness Preservation System, and some of them are presently being studied. The act provided that areas under consideration for wilderness designation should be studied for suitability for incorporation into the Wilderness System. The mineral surveys constitute one aspect of the suitability studies. The act directs that...
