Geology Comments

Aug 01, 2014 (G Seim) - The discovery reverse circulation drill hole penetrated through 11 m of overburden and 11.5 m of Paleozoic limestone before cutting 8 m into schistose intermediate to mafic metavolcanic rock. The metavolcanic rock is variably replaced by sulphide mineralization that includes pyrrhotite and chalcopyrite. Diamond-drilling in the winter of 2003 totaled 1314.5 m in six holes. This drilling intersected to zones of semi-massive sulphide in intermediate to mafic metavolcanic rock. The zones are separated by what is described as a magnetite iron formation. The upper zone is chalcopyrite rich and the lower zone is sphalerite rich. The drilling suggests that the zones strikes northeast southwest (065) and dips 78 to the northwest. The zones plunge steeply to the northeast.


Mar 07, 2007 (A Wilson) - The stratigraphic section consists of Archean-aged, steeply dipping, mafic to felsic volcanic rocks with minor amounts of interflow sediments intruded by sills and small stocks of gabbro and granite. The volcanic units have been isoclinally folded to produce a weak to very strong foliation.

Lithology Comments

Oct 05, 2009 (A Wilson) - Elevated copper values were recovered from a strongly chloritized and carbonatized rhyolite/dacite interbedded with tuff. Ash tuffs envelope the mineralized horizon. Vugs infilled with py-cp-carb were noted in the clay regolith above the volcanics. The Archean rocks are overlain by approximately 20 m of sandstone and fossiliferous limestone.

Mineralization Comments

Mar 07, 2007 (G Seim) - Discovery reverse circulation drill hole 8 m intersection averaging 1.61% Cu, 0.34% Zn, 0.13 %Pb, 9.9 g/t Ag and 0.13 g/t Au First diamond drill hole returned 1.43% Cu over 8.9 m and 1.79% Zn over 4.7 m. Hole 2 drilled underneath the 1st hole returned 0.53% Cu over 12 m and 5.45% Zn over 5.35 m. Hole 6 drilled underneath hole 2 returned 2.9% Cu and 0.45% Zn over 5.6 m, and 5.4% Zn and 0.3% Cu over 9.65 m. Holes 3, 4 and 5 drilled progressively deeper on a section 100 m to the NE of holes 1,2 and 6 returned Hole 3 - 5.25% Zn and 0.58% Cu over 3.95 m. Hole 4 - 2.41% Zn and 0.496% Cu over 8.7 m including a 6.2 m interval that returned 3.3% Zn and 0.57% Cu. Hole 5 - Not available as of 2003-04-28.


Mar 07, 2007 (A Wilson) - A 6.5 m section of drill core returned an assay range of 0.18% Cu over 0.5 m and 7.09% Cu over 0.5 m.. Average assay was 1.75% Cu over 6.8 m. Mineralization is hosted in narrow quartz-carbonate veinlets. Disseminated py-cpy-po observed in quartz flooded zones adjacent to fractures and as massive replacement mineralization in carbonate filled vugs. Assays from vuggy material returned up to 1.76% Cu and >1% Pb. The highest assay reported was 7.09% Cu 4.67% Zn, 2.68% Pb, 150.6 g/t Ag and 0.76 g/t Au over 0.5 m. The mineralized horizon consists of massive and semi-massive sulphides, plus massive and semi-massive magnetite, plus minor felsic volcanic intervals.



Alteration Comments

Mar 07, 2007 (A Wilson) - Alteration ranges from talc-chlorite (most intense) to serpentine (least intense). Chlorite extends from and decreases in intensity away from the mineralized zone both above and below the zone. Sercite and carbonate alteration have also been observed. Copper bloom was observed on core cuttings.
