1907: Miller reported that gold could be panned from pyritic and chalcopyrite-bearing dikes containing quartz veins and quartz vein breccias. 1909: Baker further described the veins. 1918: Hopkins reported that low gold tenors are associated with altered volcanic rocks and narrow and banded pyritic interflow flint, chalcedony, quartz, jasper, and banded iron formation. 1919: Knight et al. reported that on the south shore of Lake Abitibi near the mouth of the Mattawasagi (sic) River, gold could be panned from pyritic and variably chalcopyrite bearing dike material and/or sericitic schist which hosts quartz veins and quartz vein breccias. 1978: Jensen (1978, p. 61) reported that a vein grab sample obtained from the shear-hosted carbonate veins previously described by Miller (1907), Baker (1909), and Knight et al. (1919) assayed 0.01 ounce of gold per ton. 1981-1982: Nufort Resources Inc. completed VLF and HL electromagnetic, magnetic, and geological surveys and diamond drilled 6 holes totalling 2,813 feet. 1987: Nufort Resources completed VLF-EM and magnetic surveys.

Dec 07, 2005 (R Degagne) - Sampling of trenches and diamond drill core has detected anomalously elevated gold tenors (greater than 0.01 ounce of gold per ton and as high as 0.45 ounce of gold per ton) associated with narrow pyritic and variably cherty and graphitic interflow horizons which are hosted mainly by weakly metamorphosed (greenschist or lower metamorphic facies) felsic to ultramafic volcanic rocks of the (Archean) Stoughton-Roquemaure Group (Jensen 1978, Jensen and Langford 1985).

Dec 07, 2005 (R Degagne) - In one case, diamond drilling intersected a 3 foot section of jaspilitic chert containing magnetite, pyrite, and visible gold which averaged 0.45 ounce of gold per ton (assessment files, Resident Geologist's Office, Kirkland Lake). Miller (1907), Hopkins (1918), and Knight et al. (1919) indicated that anomalously elevated gold assays are also associated with pyritic and chalcopyrite bearing quartz veins and quartz vein breccias which are hosted by felsic dikes and/or sericite schists.
