SUPPLEMENTARY INFORMATION:

Cortez Gold Mines (CGM) proposes to expand its current gold mining operations 30 miles southeast of Battle Mountain, Nevada. The proposed Pit Expansion Project would not result in an increase in surface disturbance beyond the 7,676 acres previously approved. Actions associated with the Project would consist of the following: Expand the South Pipeline open pit to the east, southeast, and southwest; increase the depth of the Pipeline/South Pipeline open pit; use resulting waste rock as backfill into portions of the Pipeline/South Pipeline open pit; increase the height of the approved South Area Heap Leach pad from a height of 250 feet to 300 feet above ground surface; increase the approved Area 28 tailings and heap leach facility height from 250 feet to 300 feet above ground surface; construct an additional waste rock dump on the backfilled portion of the open pit; construct the 125-acre Gap waste rock dump; increase the approved mining rate from an average 150,000 tons per day (tpd) with a maximum of 250,000 tpd to an average of 350,000 tpd with a maximum of 500,000 tpd; translocate waste rock within the Pipeline/South Pipeline open pit, including portions of the expanded open pit; conduct certain activities at the approved Cortez facility without modification to the facility; install ground water extraction wells (ground water extraction from the existing and planned wells would not exceed the approved annualized average rate of 34,500 gallons per minute); and continue management of mine dewatering as outlined in the Pipeline Infiltration Plan and South Pipeline EIS. The proposed additional development of the South Pipeline ore deposit would provide up to seven additional years of mining and processing. The combined life of the Pipeline Project, the South Pipeline Project and the Proposed Action would be up to 25 years.
