and magnetite in irregular, drusy quartz carbonate veins and as
scattered impregnations. The mineralized zones are narrow and
very limited in length. They occur mainly along fractures cr
shear zones which continue in both volcanics and greuodiorite
and show considerabie alteration along their walis. There are
some impregnations of sulphides along the edges of granodiorite,
but the roeks now exposed probably represent approximately the
top of the granodiorite-granite batholith. However, the
intrusive history may be complex and more favouraole aspects
may occur elsewhere.
Fraser Lake Section

Throughout a large area around Endako and Fraser lake
the Mesozoic rocks are mainly intrusive. Around Encako,
especially to the south, there are extensive areas of ccarse,

red granite.

may owe their prominence in part to the greater resistance to
erosion of the mineral deposits. ‘hey are made up of granite,
partly unweathered and partly decomposed and rotten,

which with soil and drift constitutes a thin covering over
everything. Scattered in this debris along each ridge for 500
