This area is the source of more than 75 percent of Canada's gold production, which topped about $8.7 billion in 2017 alone. Other gold-bearing ores are present in Canada's westernmost province of British Columbia, as well as in its northern territories. Rocks from these regions have been found throughout the northern U.S.

Gold-rich volcanogenic massive sulfide (VMS) deposits are a subgroup of lode gold deposits, as defined by Poulsen et al. (2000). They are commonly defined by an average gold grade in grams per tonne greater than that of the combined base metals in weight percent (Au g/t > Cu + Zn + Pb wt percent: Poulsen et al., 2000).
Massive sulfide deposits of Zn–Pb–Cu–Ag type in the Bathurst Mining Camp, New Brunswick, are hosted within a Middle Ordovician bimodal volcanic and sedimentary sequence that has undergone complex polyphase deformation and associated regional metamorphism to the lower- to upper-greenschist grade.

The Bogosu-Prestea mining district of southwestern Ghana is a 33 km section of the Early Proterozoic Ashanti Gold Belt. Greenschist facies carbonaceous and carbonate-bearing turbidites and greywackes, and mafic dikes host numerous economic mesothermal gold deposits. Structurally higher ores in the Bogosu concession have brittle deformation and …
The 2698 Ma LaRonde Penna deposit, with over 71 Mt of ore at 3.9 g/t Au (280 t Au or ~9 Moz Au), is the second largest Au-rich volcanogenic massive sulfide (VMS) deposit in the world.

The three main deposit types found in the AGB are: 1. Volcanic hosted massive sulfide (VHMS) deposits, such as the rich Rouyn-Noranda district in Quebec, and at Kidd Creek, north of Timmins, Ontario. 2. Gold-rich VHMS deposits, such as the LaRonde Penna mines in Quebec 3. …
The gold is particulate within arsenopyrite grains. The RGO ore is a complex refractory gold ore. Whilst flotation and concentrate roasting, pressure oxidation (POX), and bacterial leaching (BIOX) were all studied the environmental regulators would not agree to chemically changing the arsenopyrite containing the gold.
