- 68 claims (33.5 km2) held in a joint venture between Harfang (40%), Kenorland (40%), and UrbanGold (20%) (33N02); five claims subjected to a 1% NSR shared between Geotest Corporation and Wayne Holmstead; no NSR for other claims;
- 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.
