This study describes the geological characteristics of gold mineralization along the Cape Ray Fault Zone, which hosts one of the most important vein-type gold deposits in the Appalachians. The study focuses on the lithological and structural control of the mineralization and its relationship with the structural evolution of the fault zone. It is based on detailed lithological and structural analyses and radiometric dating along a 60-kilometre segment of the Zone as well as on a detailed mineral deposit study of the gold mineralization within the Zone. The study documents a continuum of deformation from the Late Silurian to Early Devonian and demonstrates the origin of the mineralization as well as the controls on the development and geometry of the auriferous zones.

This bulletin proposes a geological classification of lode gold deposits based largely on the nature of the ore and on the geological settings of the deposits. Sixteen common types of bedrock gold deposits are distinguished and their main geological attributes are summarized. These do not correspond to an equal number of genetic types; many of these deposit types represent different components of larger hydrothermal systems and are genetically related. Most of the deposit types identified are represented by at least one large example (containing over 100 tonnes of gold). Descriptions are provided of Canadian gold deposits, including Archean & Proterozoic deposits in the Canadian Shield, Late Proterozoic to Palaeozoic deposits in the Appalachian Orogen, and Mesozoic to Cenozoic deposits in the Cordilleran Orogen. The final section discusses the application of gold deposit models.
