APEGBC Sea To Sky Branch Dinner & Technical Presentation: "Britannia Mine Remediation Project".

The Britannia Mine is located at Britannia Beach on the east shore of Howe Sound, approximately 45 Km north of Vancouver, BC. The mine site covers an extensive area, with mineral tenure associated with the mine extending over some 36.5 km2. The mine was operated from 1905 to 1963 by smelting and mining companies. At its peak, the mine was the largest producer of copper in the British Empire. The mine was closed in 1974 and since that time has remained largely derelict. 

Approximately 80 km of underground workings, numerous slopes and four open pits were developed to extract the ore. Since the mine ceased operations, surface water continues to enter the mine workings. Until the completion of the new outfall at the mine in 2005, the untreated drainage was directed to a discharge pipe into Howe Sound at a depth of approximately 26 m below sea level.

In this presentation the speakers will cover the following  topics:
• Mine history;
• Geological and geotechnical aspects of the mine;
• Techniques and processes implemented during mining operation;
• Environmental consequences and issues related to mine operation;
• Province’s remedial concept;
• Acid rock drainage (ARD), contaminated land and groundwater;
• Offshore sediments impacts;
• Remedial works planning and implementation;
• Water treatment plant and processes;
• Groundwater management system;
• Surface water diversions; and,
• Contaminated soils management.
