<br /> <br />Year 9 <br />• The last remaining ore will be extracted from the center portion of the pit <br />with reclamation expanding toward the center from north and south. <br />Complete reclamation of the dump will be possible at this time. <br />Year 10 <br />All ore will have been extracted by the tenth year and stockpiled, allowing <br />reclamation of the entire site. (Figure D.5-11 and Exhibit F) <br />D.6 Ore Deposit and Overburden Information <br />Uranium and vanadium mineralization occur as roll type, laminar, and <br />solution front deposits within the third rim of the Salt Wash Member of <br />the Morrison formation. <br />• <br />The ore horizon lies within the Third Rim Sandstone at depths ranging <br />from 50 to 360 feet. The ore body averages six feet in thickness. <br />The overburden to be removed consists of both the Brushy Basin and Salt <br />Wash Members of the Morrison Formation. The Brushy Basin, having been <br />either eroded or faulted away in the southwest portion of the property, <br />has left the Salt Wash exposed. Moving towards the northeast portion of <br />the property the Brushy Basin thickens to 300 feet. <br />The majority of overburden to be removed is Brushy Basin, which consists <br />mostly of mudstone and shale, with lesser amounts of interbedded sand- <br />stone. That part of the Salt Wash to be removed consists also of mudstone <br />• and shale but with greater amounts of sandstone. <br />D-7 <br />
