At Lemhi Pass :: Thorium Deposits Country's Largest
The Lemhi Pass thorium and rare-earth deposits in Idaho and Montana are the largest known in the U.S. Entitled "Mineralogy of the Lemhi Pass Thorium" the report says 100,000 tons of thorium oxide are "reasonably assured"...

DETROIT (ResourceInvestor.com) -- It was announced yesterday, Tuesday, February 26, 2008, in Salt Lake City, Utah, at a special session of the Society for Mining, Metallurgy, and Exploration’s annual national meeting entitled “Industrial Minerals: Rare Earths-Mining, Geology, and Metals” that a historically known-since 1949-very significant major high-grade hard rock source of thorium, presenting as thorium oxide rich mineral veins in Idaho and Montana, at sites in the geographic region known as the Lemhi Pass, has been “re-explored,” validated and quantitatively confirmed by geologists.
The specifics of the announcement were made in a paper jointly presented by geologists Richard Reed, a consultant with Idaho Engineering & Geology, Inc, and Dr. Virginia Gillerman of The Idaho Geological Survey, a state agency located in Boise, Idaho, as part of the special session named above. The paper was entitled: “Thorium and Rare Earths in the Lemhi Pass Region.” It contained the statement: “The claim holdings [being resurveyed] include the Last Chance vein in Montana, reportedly the largest and richest known thorium and rare earth vein in the United States.”

Thorium mineralization in the Lemhi Pass area, Lemhi County, Idaho Alfred L. Anderson The thorium mineralization in the Lemhi Pass area of southeastern Lemhi County, Idaho, is directed along simple to complex shear and fracture zones, and reopened copper and gold-quartz veins and lodes, in impure quartzitic and phyllitic rocks of the Precambrian Belt series. Some of the shear and fracture zones are more than 40 feet across and comprise broad zones of irregularly mineralized rock reaching distances to 2,000 feet in length. These zones contain notable concentrations of thorium and rare-earth elements along with considerable amounts of barium, alkali metals, calcium, iron, phosphorus, sulfur, and silicon and meager amounts of columbium, uranium, and perhaps other related elements. Minerals identified so far include thorite, allanite, monazite, xenotime(?), euxenite(?), apatite, specularite, barite, alkali feldspar, calcite, biotite, phlogopite, sericite, chalcedony, and quartz. The most characteristic minerals are the thorite, specularite, barite, and quartz. The specularite and thorium-bearing minerals are intimately associated and were introduced into the deposits after the micas and in advance of the barite, feldspar, calcite, and quartz. Except for the specularite and quartz and in part the barite, feldspar, calcite, and thorite, the minerals are not distinguishable without the microscope.Some of the deposits contain several percent thoria and comparable amounts of rare-earth oxides, but the average is generally under 1 percent. The area has an appreciable reserve of lode thorium. Some of the deposits are in or are being brought into production.

This report summarizes thorium and rare earth vein deposits of unpatented mining claims of Thorium Energy, Inc. located in the Lemhi Pass Thorium District of Idaho and Montana. The report supersedes previous similar reports by Idaho Engineering & Geology, Inc. (IEG). It also provides an estimate of proven, indicated, and inferred reserves of thorium and total rare earth elements in the Lemhi Pass of Idaho and Montana of Thorium Energy Inc. unpatented mining claims based upon reported reserves as resources by the United State Geological Survey (USGS) and IERCO a former subsidiary company of Idaho Power Company. Thorium and rare earth deposits in the Lemhi Pass of Idaho and Montana are the largest known in the United States. The United State Geological Survey (USGS), the United States Atomic Energy Commission (AEC), the United States Defense Minerals Exploration Administration (DMEA), the United States Bureau of Mines (USBM), the Idaho Bureau of Mines & Geology (IBM&G) – Idaho Geological Survey (IGS), Montana Bureau of Mines & Geology (MBM&G) have performed a number of investigations throughout the years in greatly contributing to the current understanding of the thorium deposits in the Lemhi Pass. In addition many private individuals, and a number of companies, including Nuclear Fuels and Rare Metals Corporation, Sawyer Petroleum and Union Pacific Railroad, Dow Chemical, Tenneco Oil Company, and Idaho Power Company to name a few have also actively explored and evaluated the mineral deposits in the Pass over the years and also have greatly contributed to their understanding.

POCATELLO, Idaho -- It's just another day in the life for Terry Andersen, going to offices, meeting people and trying to find funding for a working nuclear reactor that would create energy for southeastern Idaho. Terry's meeting with the college of technology at ISU isn't that much of a long shot. The nuclear reactor he wants to build would create electricity fueled by Thorium deposits found near Salmon. A company out of Utah, U.S. Rare Earths, Inc., wants to mine those elements. And they can be used for a lot. "The aircraft industry, the military, I think the list is endless," said ISU nuclear engineering professor Jay Kunze, Ph.D. They can also be used in computers, cell phones and batteries. Terry is hoping southeastern Idaho can capitalize on them. If the university could even produce a "small" reactor, "that would be enough to power ISU!" Terry said. Thorium reactors or not, the issue of whether mining rare earths will create jobs isn't even a question, according to the Department of Labor's regional economist Dan Cravens. "This could be huge for Idaho. We could see the location of companies in the hi-tech industries related to these elements locating here," Cravens said. Andersen says the rare earths in Salmon are potentially worth over two trillion dollars. Both Boehing and the Japanese government are interested in the deposit.
