10 Mile
Overview
10 Mile Property consisting of 521 unpatented lode claims totaling more than 10,400 acres encompassing four separate blocks, in Grand County, Utah through its wholly owned American subsidiary, Recoupment Exploration Company LLC.
Geology
10 Mile claims cover the eastern and western flanks and southern nose of the Ten Mile Anticline, in a geological setting Atomic’s management team believes is identical to the Lisbon Valley Anticline. Lisbon Valley encompasses the Big Indian mining district, which produced 77.9 million pounds of uranium oxide and 19 million pounds of vanadium from 16 large mines between 1952 and 1988 from the Triassic Chinle and Permian Cutler Formations from relatively shallow depths to in excess of 2,550 feet. This production represents more than 80 percent of the uranium ore mined in Utah during this time period. Ore grades averaged 0.34 percent U3O8, making it the highest grade of all the large uranium mining districts discovered in the United States.[i]
The 10 Mile claim blocks was staked based on the geological similarity to the prolific Big Indian District, the presence of significant uranium in the 7 Mile District of the Moab Anticline and the historic oil and gas gamma ray log anomalies at the 10 Mile Anticline.

Historic Work
Further supporting the uranium potential of 10 Mile are a series of historic oil and gas drill holes throughout the area. This drilling indicates the depth to the Moss Back is 1,400 feet on the southwestern flank and 2,390 to 2,500 on the northeast flank. Gamma Ray logs from several of these holes show spikes, indicative of uranium mineralization, within the basal section of the Chinle Formation. The basal Chinle beds are the primary location for uranium mineralization in the Formation throughout the area.
7 Mile District
Supporting the uranium potential of the 10 Mile property is the 7 Mile district, located 8 miles to the southeast. Seven Mile is located on the northwestern flank of northern nose of the Moab anticline and produced over 1,700,000 pounds of U3O8 and 890,000 pounds of vanadium from thicknesses ranging from 1 foot and 8 feet at an average grade of 0.26% U3O8 from the basal Moss Back Member of the Chinle Formation.[i]
Atomic Minerals 10 Mile claims lies approximately 95 miles by road north of Energy Fuel Inc.'s White Mesa Mill, the only fully licensed and operating conventional uranium mill in the United States.
