Exploration History

1926: claims containing the Campbell Mine were staked during the original Red Lake gold rush. Claims lapsed and were restaked several times before the mine went into production in 1949. 1944: George and Colin Campbell staked 12 claims which would become Campbell Red Lake Mines. Campbell Red Lake Gold Mines was incorporated, and property was optioned to Brewis and White Ltd. Brewis and White optioned property to Dome Exploration Canada Ltd, who now control the company through the parent Dome Mines Ltd. pre1946: 10980 m of drilling completed. 1946: Shaft sunk to 180 m and lateral work completed on four levels. 1948: Shaft deepened to 350.75 m. 1949: 300 tpd mill started. 1979: extremely high grade gold was encountered in 1221 West A Stope in the F-Zone, including “The Whopper”, which was a sample collected and estimated to contain 431 troy ounces Au. By 1980: Shaft deepened to 1316.38 m. 1981: Mill capacity increase to 1070 tpd. MINE INCLUDES 10 ZONES: G, L, K, F, A, S, O, F2, NORTH L, SILICEOUS, PRODUCTION TO 90/01/01: 6,948,736 OZ AU, RESERVES 1989: PROVEN AND PROBABLE: 6,700,000 T @ 0.634 OPT AU. 1987: Campbell Red Lake Mines amalgamates with Dome Mines Ltd. and Placer Development Ltd. to form Placer Dome Inc. 1999: Operation of the Reid Shaft commenced. 2000: Discovery on the DC Zone. Campbell Mine pours its 10 millionth ounce. 2006: Barrick Gold Corp. took over Placer Dome and sold all of Placer Dome’s central Canadian properties. On May 12, 2006, Goldcorp Inc. acquired all of the issued and outstanding shares of Placer Dome (CLA) Limited, then a wholly owned subsidiary of Barrick Gold Corporation and operator of the Campbell Mine. The Campbell Mine was integrated with Goldcorp Inc.'s Red Lake Mine, now the Red Lake Complex, to form one mining operation thereafter known as the Red Lake Gold Mines (RLGM). The Campbell Mine is now referred to as the Campbell Complex of RLGM. Production statistics subsequent to May 12, 2006, reflect a combined total production from the 2 complexes. Please refer to MDI52N04SE00012, Goldcorp Inc. Red Lake Gold Mines for data of the combined operations. 2012: Produced 507 700 ounces of gold from both the Campbell and Red Lake Complexes. Rehab work on the Cochenour Willians shaft for underground exploration of the Bruce Channel deposit occurred. Construction of a haulage drift from the Campbell Complex to the Bruce Channel deposit ongoing. 2020: Evolution Mining Ltd. acquired the mine and is part of the Red Lake Operations including Campbell, Balmer Complex, Cochenour. McFinely included in the operations in 2021. 2022: Evolution Mining developed the CYD (Campbell Young Dickenson) decline to access Upper Campbell stopes, The first Upper Campbell stope was mined in September and reconciled at 5400 tonnes grading 7.91 g/t Au. ~26 000 m of exploration drilling was conducted across Evolution's Red Lake properties.

Geology Comments

Dec 07, 2005 (K R Kettles) - The orebodies at the Campbell and Dickenson Mines are located along the eastern border of a large volcanic complex. The volcanic complex is comprised mainly of mafic flows with subordinate amounts of intercalated intermediate and felsic volcanic rocks, and chemical and clastic sedimentary rocks. Several large, sill-like intrusions, ultramafic to intermediate in composition, are present in the sequence. Several generations of mafic to felsic dikes are also present in the vicinity of the mines. The F and A Zones are classisifed as a foliation-parallel, fissure filling vein systems which are localized in a 1 to 3 m fault zone which has a sinistral displacement of about 5 m. They are situated in altered basalts, and the F Zone is south of the Campbell Rhyolite, and north of an ultramafic sill; while the A Zone is north of the Campbell Diorite, and at the southeastern end of the Campbell property. The F2 Zone is composed of quartz-arsenopyrite veins which transgresses the foliation-parallel veins of the F Zone and are commonly located along the contact between the F Zone and the adjacent wall rocks. The K Zone lies within basaltic rocks adjacent to the F Zone on the 7th level. The zone pinches out between the 7th and the 8th level against the altered rock contact. The S zone, which is located in the southern part of the Campbell property, is situated in a structure which cuts across mainly mafic volcanic rocks. The O Zone, which is located in the northeastern portion of the Campbell property, is hosted by basaltic rocks, close to two large altered rock units.

Lithology

Lithology Comments

Dec 07, 2005 (K R Kettles) - The main orebody at Campbell Mines is located near a large volcanic complex comprised mainly of mafic flows, often pillowed, with subordinate amounts of intercalated intermediate and felsic volcanics, and chemical and clastic sedimentary rocks. The complex is intruded by sills and mafic to felsic dikes.

Mineralization

Mineralization Comments

Dec 07, 2005 (K R Kettles) - The K Zone is a strongly folded foliation-oblique vein. It consists of an auriferous, layered carb-chert vein, up to 25 cm wide, which strikes NE and dips steeply to the SE. 40 m to the NW, a similar vein has been discovered. The different veins may represent an en echelon structure. The K Zone lies adjacent to a roll in the altered ultramafic sill,-mafic volc contact. The F Zone strikes W-NW, the A Zone strikes NW, and both dip 65 to 70 degs SW. They are both localized within a 1 to 3 m wide fault zone. The F Zone is at the western end of a vein system , and the A Zone is at the centre of the vein system which also includes the South C Zone (Dickenson Mines). The system has been traced along strike for over 1 km. The F, A, S, and O Zones are classified as foliaton-parallel, fissure-filling veins. The F and A zones consist of bilaterally symmetrical zones of banded carbonate along the vein walls, and a central chert-rich zone. The carb to chert ratio is higher in the F zone than in the system farther to the E, while in the A Zone the chert to carb ratio increases. Normally, 1 to 2 en echelon veins make up the F zone. The A Zone is composed of the A and A1 en echelon veins ranging from 15 to 100 cm wide and 10 to 200 m long. The S Zone is a system consisting of 4 separate structures. The Western structure has been traced for 500 m, whereas the 3 eastern structures are about 150 to 250 m in length. The Zone has an average thickness of about 0.3 to 0.5 m. The carb to chert ratio in the vein increases to the W. The S Zone is parallel to the F and A Zone structures. The mineralogy of the S and O Zones are very similar to the F-A Zones. The O Zone is a chert-carb vein which strikes almost E-W, and has been traced for about 450 m. The O Zone veins have more sulphides than in other zones. The F2 Zone is comprised of massive veins containing 70% qtz and 30% ferrodolomitic carbonate. The veins contain erratic concentrations of asp and variable gold.

Alteration Comments

Dec 07, 2005 (K R Kettles) - The Country rocks near the ore zone have been carbonatized, silicified, and have been depleted in Na20 and enriched in SiO2, K2O, and As. Basalts are comprised of quartz, chlorite, amphibole, sericite, carbonate, and locally biotite.
