The Keystone Gold-Copper District, Medicine Bow Mountains, Southeastern Wyoming
May 2002
The Keystone district includes a group of mineralized shear zones and veins that are associated with the Keystone Quartz Diorite in the Medicine Bow Mountains of southwestern Wyoming. Gold production from this district is unknown, although some estimates suggest that 7,500 to more than 12,000 ounces were produced.

Gondwana Gold and Diamonds
October 2002
Some 250 million years ago, the Earth had just one supercontinent, known as “Pangaea.” For whatever reason, the supercontinent began to break apart. South America and Africa remained joined, as “Gondwana,” until 65 million years ago, when they split apart. The obvious “fit” of South America with Africa was noted by geologists back in the 19th century, but it was not until Alfred Wegener came out with his “continental drift” hypothesis in 1912 that people took note.
