-165- the grains in the granite, carries feldspar, or is lined with it on the outer edges of the veins, It shows crystal texture, grades to the granite in places, and contains vugs which in places are lined with molybdenite. These molybdenite-quartz OO omen cee ar Oetig ee a deposits were clearly derived from the granite and formed during a late stage in the cooling in a manner similar to pegmatites. Pyrite and hematite occur very sparsely in a very fow places in the deposits. There is nothing except possibly some fine- grained sections in the granite to suggest proximity to a contact. The general distribution of the molybdenite deposits scattered here and there in the granite and not near known contacts suggests they may have been formed well within the granite. The general geological conditions here are favourable for the occurrence of an important deposit. The ~*~ —‘ings, however, suggest that the veins are too scattered and the intervening rock for the most part too lean for large sections of the rock to yield a good molybdenite content.

This quartz is crystalline and contains vugs; it grades to the granite and is closely related to it and the lenses are believed to be in the nature of pegmatites. Some of the vugs are lined with galena. Some pyrite also occurs. The rocks are cut by two or more types of Tertiary dykes (andesite and hornblende andesite) which in places carry considerable pyrite and weather rusty. The pyrite and rustiness are, of course, in no way related to the quartz veins. The deposits have been worked beeause of the galena content which carries some silver, but it is most unlikely that deposits of this character will have any economic value so far as lead or silver are concerned .
