2.2 FACILITY DESCRIPTION • The Climax Mine is an open pit and former underground mining operation that extracts molybdenite ore from the base of Bartlett Mountain and produces concentrates at the adjacent mill site. The fmal product is molybdenum disulfide (MoS2) concentrate that is transported out of the state for final processing. The Climax Mine and Mill and ancillary facilities are located neaz the summit of Fremont Pass (elevation 11,318 feet msl) where Colorado State Highway 91 crosses the Continental Divide. The mine is located 18 miles south of Frisco, Colorado, and 13 miles north of Leadville, Colorado. The site is located on both sides of the Continental Divide and encompasses portions of three major drainages: Ten Mile Creek (the most affected), Arkansas River, and East Fork of the Eagle River. All acreages affected by mine and mill operations lie completely within an approximate 14,000-acre land block owned by the Climax Molybdenum Company as shown in Figure 1. Climax Mine reached a production high of approximately 50,000 tons of ore per day in the 1970's; however, world mazkets for molybdenum radically declined in the mid-1980's and Climax curtailed production substantially until 1995. Although Climax resumed operations in 1995 due to increased demands for molybdenum, the mine is currently (May 2004) back on standby status. • 2.3 SITE SECURITY General Site Security Public entry to properties at Climax Mine can be gained by means of a number of locked gates. Many of the gates are secured by use of a conventional lock and key, while others are secured with an electronic key pad that permits entry only by inputting a 5 or 6-digit security code. The Climax industrial area is posted with numerous "Industrial Area -Authorized Personnel Only" or "No Trespassing" signs. Fencing, bemung, and barricading aze used by Climax to discourage public entry where appropriate. The main gate on Highway 91 at Fremont Pass is controlled electronically from the mine office at No. 3 Mill and the Guard House. Visitors are required to check in upon entry onto the property. It is possible for a legitimate visitor or an unauthorized person to gain entry without checking in; however, security patrols aze conducted by members of the Climax workforce (specifically the water operations staff) at various times during the day and night time hours. In addition, the Lake and Summit County sheriffs patrol the public access areas on an as-needed and random basis. The mine facility is well-lit during night time hours to discourage unauthorized entry. All essentiaUsensitive buildings aze locked during non-business hours. Many buildings are • locked even during business hours, due to the stand-by status of the mine. 4
