1 Alaska Resource Overview Kennicott Mine JOGMEC Presentation Tokyo, Japan November 7, 2006 Tom Crafford, Mining Coordinator Alaska Department of Natural Resources Office of Project Management and Permitting

2 Alaska has a long mining history HISTORICAL DATES Joe Juneau and Richard Harris discover gold at Juneau Treadwell Mines in Juneau are the largest underground gold mines in the world Klondike Gold Rush begins in Yukon Territory 1898 Gold discovered at Nome 1900 Copper discovered at Kennicott Kennicott copper mine in operation 1902 Gold discovered on Pedro Creek near Fairbanks

3 Alaska Mining Industry Defined by Three Major Periods 1. From late 1800s until 1940s - mining was the largest industry in Alaska and provided the most jobs. 2. From 1940s until effectively no hardrock mining in Alaska. 3. From 1989 to Present Red Dog & Greens Creek began operation in 1989 and there s been continued growth of minerals development ever since.

4 Historically, Gold has been focus of most mining in Alaska Much of recent gold emphasis has been on the Tintina Gold Belt But, as following map and placer districts show, gold occurs in many other areas in Alaska

19 Chuitna Coal Project (PacRim Coal)

20 Chuitna Coal Project A surface coal mining and export development located in the Beluga Coal Field, approximately 45 miles west of Anchorage. Ultra low sulfur, subbituminous coal resource, approximately 12 miles from the coast of Cook Inlet. Minimum 25-year mine life at approximately 12 million tonnes/year based on proven reserves in one (LMU-1) of three mining areas in 20,571 acre coal lease area. The proposed Project includes: a surface coal mine and support facilities. mine access road, coal transport conveyor, personnel housing; air strip; a logistic center, and coal export terminal (Ladd Landing Development). The coal export terminal would include a 10,000- foot trestle constructed into Cook Inlet for the purpose of loading ocean-going coal transport ships.

21 Chuitna Coal Project Project is currently in permitting Supplemental EIS is in preparation Permitting expected to be completed in 2008 Production anticipated in 2010

22 Western Arctic Coal Project Arctic Slope Regional Corporation and bhpbilliton billiton ASRC recently (Aug 06) announced 5 yr. exploration agreement with BHP-Billiton Underground test mine; circa 1994; coal tested in local villages

23 Western Arctic Coal Project Located in the Western Arctic Coalfield of northwestern Alaska, approximately 40 miles south of Point Lay. At Deadfall Syncline the Cretaceous-age age Nanushuk Group Contains four coal seams ranging from feet in thickness that dip at 14 to 30 degrees. The bituminous grade coal has a measured resource of 45 million tons and identified resource of 390 million tons that averages 12,900 BTUs.
