Red Lake is one of the largest, highest grade gold camps in North America.
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.
The original project focused on restarting and grading the Bateman mill, but during the FY23 Life of Mine plan work, a decision has been taken to defer this work and instead look at a whole of operation processing optimization project. This project will also take into consideration the improved performance at the Campbell mill which has been approved to trial unconstrained processing rates in the second half of FY22. The optimization project will continue into FY23. |

Summary:
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.
Red Lake mineralisation is hosted in the Red Lake greenstone belt. Mineralisation is associated with multiple episodes of volcanism, sedimentation, plutonism and deformation and is hosted in a variety of rock types within the Red Lake Greenstone belt. Economic zones of mineralisation are characterised by vein hosted gold systems accompanying sulphide replacement within sheared mafic to komatiitic basalts.
The Red Lake/Campbell, Cochenour, HG Young and McFinley deposits are hosted within significantly folded and sheared portions of the Balmer Assemblage dominated by tholeiitic basalt and komatiitic basalt intruded by felsic, mafic and lamprophyric intrusive rocks. Shear zones act as primary hydrothermal fluid corridors and host significant portions of the gold mineralisation in the area. Other significant mineralised structures occur within lower-strain areas of the stratigraphy.
Orebodies are generally steep dipping -50 to -60 degrees; lode geometry varies with relative position within the folded stratigraphy. Individual lenses of mineralisation vary considerably in thickness being mostly very narrow 0.3 – 1.0m but locally can contain multiple stacked lenses and stockworks and disseminations in excess of 10m in width. Gold appears as free milling gold, gold ........

Summary:
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.
During 2023, the first stope ore was mined from the new Upper Campbell mine at Red Lake.
Red Lake, Campbell and Cochenour Ore is 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.

Reserves at December 31, 2022:
Red Lake Mineral Resource cut-off varies from 2.5g/t Au to 3.3g/t Au and are dependent on deposit and location from surface and processing plant.
Red Lake Ore Reserve cut-off is 4.0g/t Au except for HG Young (3.0g/t Au) and Upper Campbell (2.5g/t Au).
Mineral Resources are reported inclusive of Mineral Reserves.
