Land ownership: BLM Administrative Area
Note: the land ownership field only identifies whether the area the mine is in is generally on public lands like Forest Service or BLM land, or if it is in an area that is generally private property. It does not definitively identify property status, nor does it indicate claim status or whether an area is open to prospecting. Always respect private property.

Comments

Comment (Identification): South Morton Mine indicated MSHA 4801117 as the same deposit. That is for the Golden Eagle Mine which is about 4 miles east of the North Morton Mine. The Golden Eagle is NOT part of the Morton Ranch property.

Comment (Identification): Identification and location are problematic. There are 2 old Morton Ranches on USGS maps of the area (see USGS Bull. 1147-d, Plate 1, south half), Morton Ranch (T72W, R33N, approx. Sec. 24-25) and Morton Ltd. (T71W, R36N, approx. Sec. 31). Very little is known about the original tiny prospects called Morton Ranch and their locations. Most information pertains to the much larger projects.

Comment (Identification): Morton Ranch is a huge uranium project. The northern parcel is 3500 acres, the southern parcel is 21,500 acres. In addition there are smaller scattered tracts of land. The northern parcel is mostly in T36N, R73W, Secs. 11 S2), 12, 13, 14, 23 (N2), 24 (N2). Southern parcel is mostly in T35N, R71W, Secs. 7 (S2), 18, 19, and 30; T35N, R72W, Secs. 1-16, 22-26, 35; T35N, R73W, Secs. 1, 2, 11, 12; T36N, R72W, Secs. 31-35, T36N, and R73W, Sec. 36.

Comment (Identification): A well-documented report on the Converse County Uranium Project (NI-43-101, prepared for New Horizon Uranium Corporoation on behalf of Crossroads Explorations Inc, May 23, 2006, revised Dec. 22, 2006 by RW Rozelle (Gustavson Associates) uses the name Morton Ranch as a precursor to "Scott Ranch". This is clearly not the same Morton Ranch. Scott Ranch area is in The SW part of T32N, R70W. This is well south of the T35N pf the southern/main parcel.

Comment (Location): ALONG HIGHLAND LOOP ROAP; LOCATION FROM GSW WYOMING MAP.

Comment (Production): PRODUCTION ESTIMATED AT 1 MILLION - 3 MILLION TONNES / YR.

Comment (Workings): PROPOSED MINE AND MILL, 2000 TPD (1979). CONVENTIONAL MINING TECHNIQUES EMPLOYED.

Comment (Development): MINE AND MILL PLANNED TO PRODUCE BUT SOLD TO T. V. A. IN 1979.
