From the Sutter website:

Sutter has two projects: the Lincoln Project located in Amador County, on the California Mother Lode Gold Belt, and the Santa Theresa Project located in the Northern Baja region of Mexico. Currently, the Company is completing the mill construction and underground development of the Lincoln Mine Project, beginning with the shallow portion of the Lincoln-Comet ore zone. The Lincoln-Comet and Keystone zones have a NI 43-101 compliant Indicated Resource estimate (completed in February 2008). Sutter currently controls approximately 3.6 miles of the Mother Lode of Amador County, with 90% of the property still unexplored.

In Mexico, Sutter holds the rights to the geologically similar, high-grade El Alamo district of northern Baja.
