Geological Background Piché Group – Cadillac-Larder Lake Fault Zone The Piché Group, a volcanic and ultramafic sequence in the Abitibi Greenstone Belt, is one of the most important host rock groups along the Cadillac-Larder Lake Fault Zone – also known as the Cadillac Break. Several famous gold mines along this break are either hosted in or structurally controlled by the Piché Group. These mines are concentrated in the Val-d’Or to Rouyn-Noranda corridor in Québec. Famous mines along the Cadillac Break hosted in the Piché Group: 1. LaRonde Mine – Agnico Eagle P&P=2.74Moz, MI&I=2.76Moz, >3.0km mining depth Ore: Gold, silver, zinc, copper, lead Geology: Hosted in volcanic and volcaniclastic rocks of the Piché Group and adjacent units. Gold is associated with massive sulphide lenses and vein systems, often within or near sheared ultramafics.

Lapa Mine (now closed) – Agnico Eagle P&P=0.04Moz, MI&I=0.26Moz, ~1.4km mining depth Ore: High-grade gold Geology: Located directly on the Cadillac Break. Hosted in sericitized ultramafics and volcanics of the Piché Group. Gold occurs in quartz-carbonate veins within tight shear zones.

Bousquet Mine Complex (includes Bousquet 1, 2 & 3, and LaRonde Zone 5) – Agnico Eagle 3.87Moz Historical Production, 1.25km depth Ore: Gold with polymetallic components Geology: Hosted in Piché Group mafic to ultramafic volcanics and tuffs. Gold associated with pyrite and chalcopyrite in altered volcanic host rocks. Source: https://www.mindat.org/loc-206837.html 4. Doyon-Westwood Complex – IAMGOLD P&P=1.04Moz, MI&I=3.51Moz, 2.2km mining depth Ore: High-grade gold Geology: Partly hosted in rocks of the Piché Group, particularly altered ultramafics along the Cadillac Break. Structurally controlled quartz veining in sheared volcanics. Source: https://www.iamgold.com/English/operations/westwood/default.aspx 5. Augmitto-Astoria (Rouyn Gold Project) – Lac Gold MI&I=1.66Moz, drilled to 400-600m depth Ore: Gold Geology: Hosted in ultramafic flows and tuffs of the Piché Group. Alteration includes carbonate, sericite, fuchsite, and quartz veins along shears. 1 & 4 2 3 5 21 1.
