Figure 2. Location of gold showings in and around the Lac Fagnant Property (blue outline). The northern trend of occurrences has been referred to as the Esker Zone whereas the southern one corresponds to the Cuesta Zone. Figure modified from Virginia Gold Mines (Girard, 1999).

  • 74 claims (36.5 km2) held in a joint venture between Harfang (50%) and Kenorland (50%) (33N02); no NSR;
  • Property located in Nunavik (Québec) some 55 km east of Kuujjuarapik and 160 km north of Radisson; majority of claims inside Category II Lands;
  • Accessible by air transportation (helicopter or floatplane);
  • Property located in the northwestern portion of the Great Whale Archean greenstone belt (Bienville Subprovince, Superior Province); belt mainly composed of basalts and clastic and orthochemical (banded iron formation) sedimentary rocks (Fagnant Group); minor peridotite, gabbro and felsic volcanic and intrusive rocks; surrounded by Kouri granitoids; greenschist to amphibolite facies; Great Whale iron deposit (538 Mt @ 36.7% Fe) in the southern part of the belt (outside the property);
  • Belt divided into two branches made up of abundant basaltic rocks; the eastern volcanic band appears relatively fresh and undeformed whereas the western one is variably affected by regional deformation ranging from slightly schistosed to highly sheared; structural pattern suggests polyphased deformation of the belt; known gold occurrences are more dominant in the western band;
  • More than 30 gold showings are reported; best samples returned between 1.07 and 47.03 g/t Au over submetric widths except for an interval grading 3.66 g/t Au over 8.8 m (Esker A showing); most occurrences classified as mesothermal alteration zones, other mineralization styles include quartz-sulphide and polymetallic veins;
  • Gold occurrences are mainly aligned along 2 NW-SE corridors (Esker and Cuesta) extending at least 1 km in length and up to 100 m in thickness each; Esker corridor corresponds to a base metal trend (strong Au-Pb correlation, ±Ag-As-Cu-Zn-Sb-Cd); Cuesta corridor corresponds to a Au-As and a Au only dominated trend; a Au-Cu association exists for samples collected west of these corridors;
  • Host rock commonly corresponds to schistosed basalts with alteration minerals such as biotite, sericite, muscovite, quartz, amphibole, chlorite, garnet and rare andalusite; sulphides include disseminated pyrite and/or arsenopyrite with minor pyrrhotite and chalcopyrite;
  • Historical exploration work was limited to prospecting, geological mapping, an airborne Mag-EM survey and a localized IP-resistivity survey; no drilling has ever been done;
  • Both geophysical surveys detected anomalies that need a follow-up either by mechanical trenching or drilling; an extensive sand plain masks a large portion of the volcano-sedimentary belt east of the Cuesta and Esker corridors;
  • Complex folding and structural lineaments mapped on the field and interpreted from the magnetic signature together with Fe-rich rocks such as iron formations and basalts represent, respectively, physical and chemical traps for gold precipitation.
