5.0 MINERALIZATION<br />

5.1 Regional Mineralization<br />

Base metal mineralization at the Normetal mine is in a lenticular<br />

body of<br />

massive sulphides comprising mostly pyrite, chalcopyrite<br />

and sphalerite. The deposit is in a shear zone striking N 65 W<br />

and dipping 80 NW in felsic tuffs and agglomerates. It is cut by<br />

the north trending diabase dike. The Normetal Mine produced 12<br />

million tons<br />

grading 2.20 % Cu and 5.20 * Zn with 1.4 OPT Ag and<br />

0.02 OPT Au. The mine is now shut down (NM 1989).<br />

Gold mineralization in the Casa Berardi area is stratabound<br />

associated with pyrite, arsenopyrite, quartz veining and<br />

sericite-carbonate alteration in a volcano-sedimentary<br />

environment (Descarreaux 1984).<br />

Gold mineralization in the Ligneris area is stratabound<br />

associated with disseminated pyrite in a felsic volcanic<br />

environment.<br />

5.2 Property Mineralization<br />

Quartz veins have been observed in the tholeiitic volcanics and<br />

the clastic metasediments adjacent to the contact at sample<br />

location No. l fi<br />

2 but the gold values were low.
