TGDG Presents: Geology of the Barkerville Deposit
Since 1858, the Cariboo Gold Belt of south-central British Columbia has produced approximately 3.2 million ounces of gold from alluvial production and 1.3 million ounces from lode gold mines and remains today, one of Canada’s last great underexplored gold districts. Barkerville Gold Mines’ properties encompass 182,222 hectares of mineral rights in the Cariboo Gold Belt across an area that is 67 kilometres long and 25 kilometres wide.
New mapping of the Cariboo Gold Belt conducted by BGM has defined a systematic marine transgressive sequence from fine carbonaceous mudstones --> sandstone --> calcareous sandstone --> calcareous siltstone --> limestone separated by clear transition zones. Identification of these facies is key to understanding the mineralization on a local and district scale and unravel the complex folding and faulting history. Detailed structural mapping on surface, underground and utilizing systematically oriented core has helped BGM to identify evidence a previously unrecognized late deformation and clearly define kinematic controls on vein mineralization.
