<br />Description of the Environment <br />The Rimrock Mine permit area is situated on steep terrain dissected by numerous <br />drainages (EXHIBIT AA). The local topography is largely shaped by tributaries of the <br />Purgatoire River. <br />Elevation on the mine property ranges from about 6,500 feet in the valley where <br />Engleville Gulch flows out of the permit area to 6,900 feet in the eastern part of the <br />property. The climate is semi-arid with annual precipitation of 13" to 15". Prevailing <br />winds are from the southeast at an average speed of 8 miles per hour. <br />The permit area lies within the Engleville Gulch watershed, whose resident stream is an <br />ephemeral tributary of the Purgatoire River. Engleville Gulch headwaters are on the <br />northern flank of Fisher's Peak to the southeast of the mine permit area. The major <br />topographic feature in the area is Fishers Peak, a large, regional mesa. Geologically, <br />the mine is centrally located along the eastern edge of the Raton Basin which is an <br />asymmetrical syncline structure with a steep to overturned western limb and gentle <br />eastern limb. Structural dip of the sedimentary sequence in the permit area is <br />3 <br />
