Open-pit gold mine operated by Agnico Eagle Mines Limited; it has a 8-year life expectancy (2010 – 2017). Mining is from the "Portage open pit."

Gold deposits are found along two main structural features – the Meadowbank Trend and the Pipedream Lake (Northeast) Trend. The Meadowbank Trend hosts the Goose, Portage and Vault deposits, which are the sites of initial mining. These shallow deposits lie within 7 kilometres of each other. In all deposits, gold mineralization is commonly associated with intense quartz flooding, and the presence of sulphide minerals (pyrite and/or pyrrhotite). [From Agnico website.]

Located 86 km (53 mi) north of Baker Lake (110 kilometres by road) and 300 kilometres west of Hudson Bay.
