LaRonde gold mine

LaRonde Underground Mine is located 44 km W from Rouyn-Noranda, Quebec, Canada.

LaRonde is Canada’s fourth largest gold mine.

LaRonde has produced almost 6 million ounces of gold since it opened in 1988. LaRonde’s 2.2-km deep Penna Shaft is now the deepest single-lift shaft in the Western Hemisphere. LaRonde achieved commercial production of its deep extension (that is, below level 245) in November 2011, where approximately 94% of its ore is now mined. Gold production is expected to be 340,000 ounces in 2019 and 345,000 ounces in 2020, reflecting the higher gold grades expected at depth. LaRonde currently has a mine life lasting through to 2025.

Mine Type‎: ‎


Deposit Type:

Gold-rich volcanogenic massive sulphide deposit


100% – Agnico Eagle

Mining Method(s)‎:

Longitudinal retreat with cemented rock or paste backfill, and transverse open stoping with cemented rock backfill, paste or unconsolidated backfill.

Processing Method(s):

LaRonde mineral processing complex, which includes copper and zinc flotation as well as precious metals recovery and refining. The processing plant produces doré bars containing gold and silver, as well as zinc and copper concentrates that also carry valuable gold and silver credits.

The plant has a daily capacity of 7,000 tonnes of ore, and has been expanded four times since it opened in 1988. In addition, a dedicated 2,000-tonne/day carbon-in-leach processing facility treats ore trucked from the adjacent LaRonde Zone 5 mine and refines its concentrates into doré bars. This plant formerly treated ore from the now-depleted Lapa mine.

The LaRonde plant also treats concentrate pulp trucked from the Goldex mill. The material is sent to the LaRonde leaching/carbon-in-pulp circuit for gold recovery along with LaRonde residual pulp.
