Feb 26, 2018 (Therese Pettigrew) - At the extremity of McKellar Point, there is a large development of the red syenitic rock in connection with trap dykes of the usual basic nature and dark appearance. The syenitic rock varies in different places from a highly crystallized rather coarse-grained red rock, showing distinctly to the eye the red feldspar associated with the green, apparently hornblendic, mineral, whereas in other places, whilst presenting the same general colour and appearance as the typical syenite, it is much finer grained, and has more the appearance of a clastic rock which has been somewhat metamorphosed. Here also nothing can be definitely said of the origin of these rocks without further work being done. This syenitic rock has a distinctly bedded appearance at this point, showing a dip to the east at about 15 degrees. Another curious feature here presented consists in the occurrence of inclusions, which have the appearance of bent and twisted pieces of argillite which have been metamorphosed (Tanton, 1931).

Feb 26, 2018 (Therese Pettigrew) - Numerous veins of the usual nature cross the point in a more or less northwesterly direction. They carry a little of the ordinary metallic minerals of the district in a gangue of barite and calcite, with some colourless and amethystine quartz. A little work has been done on some of them, notably on one on the north side of the point, on which an 80-foot tunnel has been run in and a shaft about 30 feet deep sunk (Tanton, 1931).
