Mine Life2026
The Meadowbank Complex refers to the processing facilities and infrastructure at the Meadowbank mine, combined with the mining and infrastructure at the Amaruq mine site.

The Meadowbank gold mine achieved commercial production in March 2010. The final year of production at the Meadowbank mine was 2019, with mining operations at the Complex gradually transitioning to Amaruq, which today provides the sole source of mill feed. The Company declared commercial production at the Whale Tail pit at Amaruq mine on September 30, 2019.

The Amaruq mining operation uses the existing infrastructure at the Meadowbank mine, including mining equipment, mill, tailings facilities, camp and airstrip.

Mining concluded at the Meadowbank site in 2019.

Deposit Type

  • Iron formation hosted
  • Mesothermal
  • Vein / narrow vein

Summary:

The Meadowbank property comprises a number of Archean-age gold deposits hosted within polydeformed volcanic and sedimentary rocks of the Woodburn Lake Group, part of the Western Churchill supergroup in northern Canada.

Three mineable gold deposits, Goose, Portage and Vault (all now mined out), have been discovered along the 25-kilometre long Meadowbank gold trend, and the PDF deposit (a fourth deposit) has been outlined on the northeast gold trend. These known gold resources were within 225 metres of the surface, making the deposits amenable to open pit mining. In addition, two mineable deposits have been discovered at the Amaruq satellite deposit, the Whale Tail and V Zone, which come together at depth northeast of Whale Tail Lake. Both extend from surface, making them amenable to open pit mining. A ramp is being driven between the two deposits and is currently 350 metres below surface, in the footwall of Whale Tail deposit.

The main mineralized occurrences at Amaruq are hosted within a northeast-trending sequence of mafic and ultramafic sub-volcanic to volcanic rocks interlayered with various combinations of fine-grained clastic rocks, chert, graphitic iron-rich mudstone and iron formation. They correspond to mesothermal-type lode-gold mineralization, including (but not restricted to) hybrid, stratiform and vein-type iron-formation-hosted gold deposits.

Mining Methods

  • Longhole open stoping
  • Cemented backfill

Summary:

All ore at the Meadowbank Complex is now sourced from the Amaruq satellite deposit at Meadowbank. Mining at the Amaruq satellite deposit has historically been done by open pit methods using excavators and trucks. The ore is extracted conventionally using drilling and blasting, then hauled by a long haul off-road truck fleet to the mill at the Meadowbank facilities for processing. Commercial production at the Whale Tail pit was achieved on September 30, 2019. The V Zone (IVR pit) began pre stripping activities in the third quarter of 2020 and achieved commercial production on December 31, 2020.

Mining activities at the Amaruq satellite deposit have transitioned to underground mining, with commercial production achieved as of August 1, 2022. A surface portal and ramp are being used to support development and operations at the underground site. The ramp is currently at a depth of approximately 380 metres below surface and in 2022 approximately 3,800 metres of underground development was completed. Approximately 5,500 metres of underground development is planned for 2023. The mining method used at the Amaruq underground deposit is long-hole open stoping and primary stopes are being backfilled using cemented rockfill.

A traditional truck and scoop tram approach is being used for underground mucking and hauling. Once at surface, ore is hauled by a long haul off-road truck fleet to the mill at the Meadowbank facilities for processing. Ore from the underground m ........
