The Juneau Gold Belt

Click to Enlarge

The Juneau Gold Belt was one of the world’s largest gold producers at the turn of the 20th century with both the Treadwell and AJ (Alaska Juneau) mines in production. A total of 6 million ounces of gold were produced from these mines with 3.2 million ounces being produced from the Treadwell mine to a depth of 1,700 feet.

Century’s other properties in the Juneau Gold Belt include the Yakima Property, Eagle River Mine, Sweetheart Property, Patton Property, Peterson Property, Dream Property, and Bessie Property. Century plans to option, joint venture or place the Alaska properties in another company to finance the exploration.

Treadwell Mine

The Treadwell Mine is Century’s anchor project on the Juneau Gold Belt. In the early 1990s Echo Bay Mines drilled a long hole across Gastineau Channel to test the continuity of the mineralization to depth. At an elevation of 3,000 feet, which is 1,300 feet below the Treadwell workings, the hole intersected 187 feet of 0.101 opt Au, containing a section of 44 feet of 0.22 opt Au. This extremely wide intersection was typical of the width and grade originally mined from the Treadwell during the mine life.

Yakima Property

• The Yakima property is located 450m west of and parallel to the Treadwell mine. The properties are thought to be related due to their close proximity and similar geology to each other. Both properties contain long low grade gold intersections.

• Gold and base metal mineralization has been cut in 3 drill holes designed to test gold and base metal soil anomalies.

• DDH-1: 75 feet of 0.2% Cu; 7.5 feet of 0.027 opt Au.

• DDH-2: 166.5 feet at 0.03 opt Au, including 26 feet at 0.14 opt Au and 8 feet at 0.3 opt Au hosted by quartz diorite similar to the Treadwell diorite.

• DDH-3: 219 feet at 0.25% Zn, including 50 feet @0.5% Zn, 15 feet of 0.022 opt Au and 36 feet of 0.017 opt Au.

Eagle River Mine

• Past producer of 22,500 ounces of Au between 1904 and 1912.

• The “ Flume ” Tunnel encountered an ore shoot measuring 300 foot long, 36 foot wide stringer zone assaying 0.18 opt Au, which contained a 4.5 foot zone assaying 0.59 opt Au on the hanging wall.

Sweetheart Property

• Cu, Zn, Ag, & Au mineralization extends over 12,600 feet strike length.

• Tested by 16 shallow diamond drill holes which returned Cu to 1.4%, Zn to 3.2%, Ag to 1.3 opt, and Au to 0.27 opt. (see details in Technical Report, October 2004 available on www.sedar.com).

Patton Property

• Under-explored, high-grade Au veins in phyllites.

• Four small adits on property. Vein in 3 adits averages 1.3 feet wide over 100 feet.

• Sampling by United States Geologic Survey returned 2.2 and 1.9 opt Au over 0.7 feet and 0.7 feet respectively.

Peterson Property

• Historical prospecting identified gold mineralization within an arsenic soil anomaly which covers most of the property.

• Stream sediment sampling returned significant Au values in pan concentrates.

Dream Property

• Placer Dome discovered a high grade breccia pipe in an area of stratabound polymetallic mineralization.

• Selected grab samples returned grades up to 0.4 opt Au.

Bessie Property

• Under-explored, high-grade Au veins in phyllites.

• Four old adits on Bessie vein at north end of property; four adits and shaft on the Alaska Washington vein at southern end of property. Produced 300 oz. Au. Vein in adit #2 exposes a section 50 feet long by 18 inches wide that averages 0.431 opt Au.
