The Struggle to Reopen Alaska's Largest Gold Mine
The historical AJ mine, located east of Juneau, Alaska, was considered the largest gold mine in the state at one time. Joe Juneau and Richard Harris struck gold there in 1880, and it has been more recently known as a tourist destination.

The strike and the dip of the veins can be broken down into two categories: veins in the eastern area and along Lander Hill, and the veins in the southwestern portion of the district.

Gold Rush Continues in Africa
…some miners are doing exceptionally well… with a few obtaining amounts estimated in the millions of dollars.
