The register’s text, word for word

Description

Dredge No. 4 is a preserved bucketline sluice dredge used to mine placer gold. Located at its last place of operation on Bonanza Creek in the Klondike goldfields just outside of Dawson City, Yukon, it is now preserved and operated as a historic site.

Heritage value

Dredge No. 4 was declared a National Historic Site of Canada as symbolic of:

  • the importance of dredging operations in the Yukon (1899-1966), and
  • aspects of the evolution of gold mining in the Klondike from early labour-intensive to later corporate industrial phases of gold extraction.

Dredge No. 4 was constructed in 1912-13 by the Canadian Klondike Mining Co. to mine the gravels of the Klondike River Valley. It was dismantled when paying gravels ran out in 1940. All of its major mechanical components were refurbished by the Yukon Consolidated Gold Corporation and encased in a new wooden hull and superstructure built on Bonanza Creek. From September 1941 to the fall of 1958 it mined Bonanza Creek. There, it sank on its present site in 1959. It has since been preserved as a National Historic Site.

The heritage value of Dredge No. 4 lies in its association with Klondike gold mining and in its illustration of the process of bucketline sluice dredging used by corporations to mine placer gold in the Klondike Gold Fields in the 1899-1966 period.
