Prince Albert Mine Plan of Operations Site Description <br />It is considered relevant to the mine site hydrologic condition primarily due to its potential to limit <br />recharge to the Salt Wash Member up gradient of the mine site where it is still present under the <br />highly transmissive Dakota Sandstone Formation. The Salt Wash Member, in turn, overlays the <br />Wanakah (ex. Summerville) Formation, which is up to 90 feet thick in the Club Mesa area. The <br />Wanakah Formation consists of red shale alternating with mudstones in even, horizontal beds that <br />were deposited in a quiet transitional environment following the retreat of marine conditions at the <br />beginning of the Glen Canyon time. The lithology of the Wanakah and its stratigraphic geometry are <br />strong influences on its hydrologic properties. The Wanakah has a very low hydraulic conductivity <br />( <1.0x10E which makes it a very effective aquitard (or even an aquiclude) (UMETCO 1997). <br />3.9 Paleontological and Cultural Resources <br />The Morrison Formation is a dinosaur - fossil bearing formation in the United States. The San <br />Juan/San Miguel Resource Area Resource Management Plan (RMP) (1985) does not provide <br />specifics for paleontological resources, stating that this resource category needs further study. The <br />Grand Junction Resource Area RMP (BLM, 1987) classified all formations in this resource area as <br />having the likelihood of significant fossil occurrence (usually vertebrate fossils of scientific interest). <br />The BLM Grand Junction Field Office has classified the entire Morrison Formation as Class 4 -5 <br />paleontology category, which indicates the formation is known to, or is likely to, produce vertebrate <br />and/or scientifically important fossils. It is possible that dinosaur fossils may be encountered in the <br />Prince Albert underground mine workings or on the surface of the project area. Dinosaur fossils are <br />primarily contained in the shales and mudstones of the Brushy Basin Member of the Morrison <br />Formation in this part of the western United States, but these fossils have also been discovered in the <br />Salt Wash Member of the Morrison Formation. The likelihood of finding dinosaur fossils at the <br />Prince Albert mine is reduced somewhat by the fact that both the surface and underground portions of <br />the mining operation lie entirely in the Salt Wash Member since the Brushy Basin Member has been <br />weathered away at this location. <br />The USBLM Uncompahgre Field Office has conducted a cultural resources survey of the proposed <br />Prince Albert Mine site in 2010 and the results of that survey are incorporated by reference. No items <br />of concern were found. <br />3.10 Permanent Man -Made Structures and Owners <br />There are no permanent man -made structures or residences within, adjacent to, or in the nearby <br />vicinity of the proposed Prince Albert mine area. <br />Rimrock Exploration and Development Page 8 of 27 <br />
