St. Paul and adjacent properties lies on the relatively flat top of
Thornhill mountain. A white albitite dyke with a width up to 20
feet extends for about a half mile across the top of tho mountain,
with a southeast strike swinging to easterly and spe Ageene
easterly toward the east, and continues down both the east and west
sides of the mountain. On the mountain top, 400 fect from the
northern edge, a shear zone and fault striking northeast, cross

the dyke and extend down the west slope where they are prominent

on the A and B group. Northwest of the shear zone the white
albitite dyke branches. The branch, kmown as the Sadic dyke,
follows a more easterly course than the main dyke and continues

to the shear zone where it apparently narrows and ends. The main
dyke, knovm as the St. Paul, continues across the shear zone,
though probably offset a little.

The rocks bordering the Sadie and St. Paul dykes exhibit
considerable shearing and shattering and the dykes in places are
also affected. In places in this sheared and shattered rock, on
one side or the other of the dyke or in the marginal part of the
dyke, there is mineralization and the rocks are silicified and
changed to white mica. In places the mineralization widens to
3 feet of solid vein-quartz. One lens with this width is 60 feet
long. In the main, however, the mineralized zone is narrow or
intermixed with the country rock and there are long stretches
where little if any mineralization occurs. It consists of quartz
and albite with galona, sphalerite, chalcopyrite, pyrite, and, it
is reported, free gold. Values in places are said to run as high
as 1.5 ounces in gold and the dyke is also said to carry 0.02

ounce of gold to the ton.
