The Lac Anuc area (NTS 34O) was mapped at the1:250,000 scale in the summer of 2001, within the context of the Far North Project. The area lies 150 km east of Puvirnituq, between latitudes 59° 00' and 60° 00'N and longitudes 74° 00' and 76° 00'W. The rocks of the Lac Anuc area were classified into four lithodemic complexes, eight intrusive suites and four lithodemes. They underwent three episodes of ductile deformation (D1 to D3) and three episodes of brittle-ductile deformation (D4 to D6). Phase of deformation D1 is coeval with the emplacement of volcano-sedimentary units (grouped into three complexes of less than 30 km by less than 150 km in size and dated at ca. 2851 to less than 2729 Ma), as well as tonalite-trondhjemite units (ca. 2848 to less than 2740 Ma). Phase of deformation D2 is also synplutonic and synvolcanic, but it controls the emplacement of granite-granodiorite units (ca. 2732 to 2723 Ma), mafic to ultramafic rocks (MU) and enderbite-opdalite-charnockite-diatexite units (ca. 2729 to 2682 Ma). Phase of deformation D3 is late (2693 to 2675 Ma) and is responsible for the formation of NW-SE to NNW-SSE-trending shear zones. Brittle-ductile deformation events (D4 to D6) control the emplacement of a late Archean syenite (ca. 2643 Ma) and three sets of Paleoproterozoic dykes (less than ca. 2209 Ma). The economic potential of the Lac Anuc area is outlined by the presence of volcanogenic Zn + Cu occurrences, Cu + Au ± Ag occurrences in synvolcanic glomeroporphyritic anorthosites, gold-bearing iron formations, and Au + Ag + Cu occurrences in shear zones. These occurrences form 18 showings, all hosted in volcano-sedimentary units.
