Two Uranium Exploration Firms Slug It Out In Utah’s Lisbon Valley, Half One
After interviewing SXR Uranium One Chief Government Neal Froneman, we realized it was important to cowl developments in Utah, particularly in the Lisbon Valley. Every time Mr. Froneman talked about Wyoming, he practically all the time included Utah in the identical breath. Vacuum/Atmospheric Distillation Unit Most of our focus for the primary half of 2006 had been on the In Situ Recovery (ISR) technique of uranium mining. Now, because the uranium spot price knocks on the $50/pound level, it seems conventional mining in the United States could return with a vengeance.
Utah is strictly excessive grade uranium underground mining, presumably providing some the consistently highest grades out there in the United States. Worldwide Uranium Company’s announcement to reopen the White Mesa uranium mill, some 50 miles away from the Lisbon Valley, was the first step geared to renew interest in southeastern Utah’s Paradox Basin. SXR’s curiosity in the realm was a major second step. There may be a number of extra causes if the early drilling results of two junior exploration companies show promise deep beneath this semi-arid floor lined with juniper, sage brush, and sprinklings of Ponderosa and Pinyon pines timber.
Utah is a state where underground uranium mining was profitable and continued until the spot price fully collapsed. Particularly, it was the Paradox Basin of the Colorado Plateau, which grew to become world well-known, partly due to a Hollywood movie about its most colorful pioneer, Charlie Steen. His dwelling in Moab, Utah grew to become the town of millionaires, a consequence of the uranium rush he launched with his discovery.
Lisbon Valley grew to become the most closely promoted uranium districts on the earth, due to a then-penniless Charlie Steen, the unemployed petroleum geologist who found the Mi Vida uranium deposit on the southwest aspect of the Lisbon Valley anticline. On July mexico oil fields map 6, 1952, Charlie Steen cored by way of 14 feet of grayish-black pitchblende – specimens of which he had solely seen in museums. Nobody had ever before discovered pitchblende on the Plateau. With uranium grades up to 0.Four %, this grew to become one of the richest ore bodies mined within the United States.
Our latest investigation and interviews with two geologists revealed there may very well be an space play again developing within the Lisbon Valley uranium district. It is also referred to as the massive Indian Uranium District, named after the ore belt, and is positioned 30 miles south of Moab, Utah – about halfway between Salt Lake Metropolis and Santa Fe, New Mexico. Excluding U.S. Energy, which holds potential uranium properties on the west mexico oil fields map side of the Lisbon Valley Fault, there are three junior uranium exploration corporations exploring or hoping to discover for uranium on the northeast facet of the Lisbon Valley Fault. They hope to continue where Rio Algom left off, throughout the nadir of the twenty-yr uranium depression.
Why are the Uranium Companies
Exploring the Northeast Flank of the Fault
While the west aspect of the fault has been essentially the most productive uranium mining floor, Rio Algom discovered a mineralized zone in 1972 on the “nose” of the northeast side of the fault. For the next sixteen years, the corporate’s Lisbon Mine produced about 24 million pounds of uranium from more than 5.6 million tons of ore at an average grade of zero.22 %. True, the grades have been greater on the western aspect of the fault – a mean grade of 0.35 % U3O8.
Rio Algom’s discovery and outstanding uranium manufacturing confirmed a bit publicized notation in an obscure chapter, of a geological textbook, entitled, “Geology and Exploitation of Uranium Deposits within the Lisbon Valley Area, Utah.” Hiram B. Wood of the American Institute of Mining, and on behalf of the U.S. Atomic Power Commission, wrote in 1968, “An Extension of the massive Indian Ore Belt, comparable in dimension and grade to the known ore belt, probably happens within the downthrown block north east of the Lisbon Valley Fault at depths of 2400-2700 ft beneath the Dakota-capped floor…leaving this space as essentially the most favorable unexplored area remaining on the Lisbon Valley Anticline.”
It ought to be noted that none of the major uranium ore bodies had outcrops. The entire discoveries have been made by exploration drilling. Because of the stratigraphy, the mineable deposits were discovered at depths of more than 2000 toes. “All of the anticlines in the Paradox Basin, of which Lisbon valley is one, are salt structures,” mentioned Richard Dorman, vice president of exploration for Universal Uranium, which is now drilling on the northeast side of the anticline. Dorman defined an anticline for the layman, “It’s where the earth will get bent up into a rounded dome.”
It may be fairly potential there may be more uranium, based on the 2 uranium exploration geologists we interviewed for this function. Both Universal Uranium and Mesa Uranium are drilling to establish and evaluate the Moss Bach sandstones in the Chinle formation. It was Charlie Steen’s uranium discovery overlying the Moss Bach member which began the massive prospecting rush into the district within the 1950s. The majority of the uranium manufacturing occurred along the northwest flank of the anticline. For forty years, more than eighty million pounds of uranium have been mined from the sixteen mile long by one-half mile large trend of the western flank.
Exploration drilling is underway on the northeastern facet of the anticline close to the previously producing Lisbon Mine. There are geological advantages in the exploration packages of each firms, Common Uranium and Mesa Uranium. Universal’s smaller property place is six miles lengthy and two miles wide, however nearer to the fault. Mesa’s bigger place is nearer to the former Lisbon Mine, however is an arc shaped land position further from the fault. International Uranium, which has not introduced a drill program, is reportedly sandwiched in the area between the 2. ALL RIGHTS RESERVED.
