The Galore Creek region is mainly underlain by Upper Triassic volcanics and sediments of the Stuhini Group. This area is flanked to the west by Juro-Cretaceous quartz diorite to granodiorite of the Coast Plutonic Complex. Middle Triassic sediments with Permian sedimentary and metamorphic rocks are at the northern and eastern limit of the area. Permian limestone is the dominant rock. North trending faults define boundaries between Upper and Middle Triassic rocks and between Paleozoic and Triassic rocks. Strata is folded into a linked series of anticlines and synclines with west or northwest trending axes. Younger folds with north-northwest trending axes transect the earlier formed structure. Syenite (orthoclase porphyry) intrusions of Juro-Triassic Age disrupt the stratigraphy and structural trends. These intrusions form a series of dykes, sheets and stocks. Eocene Age intrusions of quartz monzonite have formed several stocks and are the youngest rocks in the area.

The OP claim area, located southwest of the Galore Creek-Scud River junction, has been mapped by Souther (Geological Survey of Canada Map 11-1971) as consisting of Middle to Upper Permian limestone with minor sediments. These sediments are bounded to the south by a strong northwest trending fault, south of which exist Stuhini Group volcanics. Thin bands of hornfels, along with some highly weathered volcanics, occur intermittently along the fault.

Old trenches and pits revealed pyrite and pyrrhotite mineralization occurs in gossanous and weathered volcanics. Some minor chalcopyrite is associated with the iron sulphide mineralization.

The location of the original OP (from Assessment Report 682) is vague and may be in the vicinity of the new Malachite Pup and Pickston showings. The Pup claims (1989-1991) covered the plotted area of the OP showing and the reader is referred to the new Saddle Grid showing for details.
