The Red Lake operation is an underground mine, operating in three different historical mining complexes (Red Lake, Campbell and Cochenour) and the recently acquired Bateman Gold Project.

The Campbell-Red Lake and Bateman gold deposits are located within the Red Lake greenstone belt of the Superior Tectonic Province. This belt is host to one of Canada’s largest and richest Archean gold deposits producing more than 26 million ounces of gold since the 1930s. The Red Lake Greenstone Belt is subdivided into several rock assemblages recording magmatic and sedimentary activities that occurred from 3.0 to 2.7 billion years before the present. The tholeiitic and komatiitic metabasalts of the Balmer Assemblage are the oldest volcanic rocks in the belt and are host to the major gold deposits in the Red Lake district, including the Campbell-Red Lake and Bateman deposits.

Gold mineralisation is mainly associated with silicification and sulphide minerals that replace carbonate veins, breccias and wall rock selvages. The carbonate veins and breccias, which are composed of ankerite ± quartz, were formed before and/or in the early stage of penetrative ductile deformation, whereas silicification, sulphide replacement and gold mineralisation were coeval with deformation.

The Cochenour Complex covers mineralization discovered at the Western Discovery Zone deposit and the former Cochenour–Willans mine. It also includes the former Gold Eagle Mines Joint Venture pr ........

The Red Lake Operation operates three different historical underground mines (Red Lake, Campbell and Cochenour) and two processing facilities (Red Lake and Campbell Mills). The recently acquired Bateman Gold Project has added a fourth orebody and a third processing plant, resulting in a consolidated mining region with numerous opportunities to maximise production and margins. Data integration and re-modelling of the Bateman orebody is underway and will enable optimisation of the consolidated assets to deliver on our strategic vision for the region.

Red Lake, Campbell and Cochenour Ore is currently hoisted to surface through two production shafts - Cochenour and Campbell ore via the Reid Shaft and Red Lake via the #3 Shaft. The Campbell Young Dickenson (CYD) surface decline commenced in July 2021 and will provide access to the historic Upper Campbell resource - a key driver in the production ramp up over the coming years. Ventilation is a push-pull system consisting of 4 intake and 5 exhaust fans and 15 underground booster fans.

Mining dates back as far as 1939 at the Cochenour deposit, and the current Red Lake Gold Mines organisation dates to the 2006 acquisition of the Campbell mine by Goldcorp.

Mining is carried out with a company-owned fleet of mining equipment, supplemented by contractor production drills.
