Sep 15, 2020 (Therese Pettigrew) - The property is underlain by intensely foliated mafic to felsic metavolcanic rocks which have been intruded by quartz porphyry masses and sills of metadiabase. Conglomerate and arenite of the Seine Group underlies the southeastern part of the property. Foliation strikes 265 degrees and dips 75 degrees N. Foliated rocks commonly contain abundant ankerite and rhyolitic rocks exposed in the northern part of the property are very sericitic (Poulsen, 1984). The B Zone consists of a relatively narrow (up to 15 m) mafic unit intercalated with rhyolite flows. The mafic unit has been strongly folded. This deformation has been accompanied by strong iron carbonate alteration and veins and pods of quartz, primarily in the noses of parasitic folds (Assessment report 52C15SE8115).

Sep 15, 2020 (Therese Pettigrew) - Chalcopyrite and pyrite are common constituents as disseminations in foliated metavolcanics and metadiabase. Minor quartz-ankerite veins also contain sulphides. Diamond drill holes testing geochemical anomalies in the north-central part of the property encountered minor sulphides associated with silicification. Assays of 0.12 percent Cu and 0.03 percent Zn over 1.7 m were reported from a single intersection (Poulsen, 1984). The Turtle Tank B Zone consists of quartz and quartz-carbonate veinlets filling strongly fractured to brecciated rock, apparently localized at a fold nose or along a fold crest. Pyrite and chalcopyrite occur within the veinlets as disseminations, fracture fillings, and as small pods up to about 10 cm by 30 cm. Gold values up to 24 07 g/t Au have been reported from grab sampling, and values of 13.2 g/t and 11.6 g/t Au have come from chip samples over 2.5 and 2.0 metres respectively, both containing about 2% chalcopyrite. The highest value returned by the 1991 channel sampling was 4.32 g/t Au over 1.5 m from the B Zone. DDH NTT96-07 returned up to 2830 ppb Au over 0.06 m. DDH NTT96-08 returned 2480 ppb Au over 0.22 m, 1765 ppb Au over 0.32 m, and 0.6% Cu, 900 ppb Au and 11.6 g/t Ag over 0.26 m. DDH NTT96-01 returned 374 ppb Au and 1.19% Cu over 0.98 m. DDH NTT96-05 returned 0.1% to 0.53% Cu over lengths up to 1.0 m (Assessment report 52C15SE0029).
