The Prince George group of claims is in Magee pass on the south fork
of Marmot river. A quartz vein up to 4 feet wide in granite contains
pyrite, chalcopyrite, galena, and sphalerite.

Figure 12. Plan and vertical section, Prince John group.

The country rock is volcanic in origin, but has been sheared to a
chlorite schist. The planes of schistosity strike north along the hillside
and dip westward into the hill at moderate angles. The schist has been
partly replaced by chalcopyrite and pyrite across a width of 40 feet.
The length of the mineralized zone is not known. The sulphides occur
in small particles through the mineral zone and also in small, lenticular
veinlets and gashes paralleling the schistosity.

The mineralized zone is revealed in an open-cut at an elevation of
2.235 feet. An adit commences 15 feet below and a short distance east of
the open-cut. The adit is about 180 feet long and was driven westerly.
