Book Description
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.

Book Description
Papers of a symposium held at Val d'Or, Quebec featuring gold deposits of the Abitibi Greenstone Belt from Val d'Or to Timmins and including some other gold deposits in Canada. Current descriptions of the deposits with thoughts on their genesis and techniques used in exploration are presented.

Book Description
Gold is recognized globally as a symbol of wealth, success and fortune. It plays an important role in Canada's economy. In 2011, gold production ranked fourth for the total value of mined metals in Canada and first in the number of operating mines in the country. 1 Despite recent increases in exploration, Canadian gold reserves have significantly declined in the last two decades. The Gold Ore Systems Project will collect data about the nature, location and depth of gold deposits. The project will study three main gold deposit types: banded-iron formation-hosted deposits; intrusion-related deposits; large, fault-related Archean gold districts.
