Dec 07, 2005 (G Seim) - From report by B.S.W. Buffam (1937) in T-585 On claim 11256 3 narrow altered basic syenite dikes outcroup and associate with them are numerous white quartz veins. The dikes strike northeast and dip northwest. The dyke rocks are frequently well mineralized with disseminated pyrite and a grab sample from this was reported to carry values of from $11.00 to 14.00. Some surface sampling and 5 diamond drill holes were put down across all three dykes, No values were obtained from either the surface sampling or from the drill cores. It must therefore be assumed that the values obtained from the grab samples were erratic.

Notes: The Dayton Porcupine No. 3 zone was visited by Glenn Seim and Nicholas Campbell on July 30, 2003. A overgrown (alders) bush trail least east off of Pine Street south. The bush trail leads to within 20 m of the area of trenching. The trenches are located in an outcrop of pillowed mafic volcanics that are cut by mafic syenite dikes and quartz veins. The quartz veins are hosted by the syenite dikes. Trenches on white quartz-sulphide veins are at UTMs 4762189E/5358498N and at 476212E/5358466. The vein at the former is 25 cm wide for most of its length but splits at its northern end into a structure up to 1 m in width. The vein at the 2nd location is up to 1.5 m in width. Both veins strike 220/80NW. The veins are mineralizes with blebby to euhedral pyrite and some chalcopyrite. Sulphide content is highly variable, comprising up to 10% of the vein. Disseminated euhedral pyrite also occurs in the syenite (up to 5 %) and in the mafic volcanig 1-3 %.
