Geology Comments

Dec 07, 2005 (S Fumerton) - The main shear zone consists of a series of weak shear zones / faults which form a network of intersecting shears outlined by iron carbonate alteration. There are abundant parallel fractures in the host rock adjacent to the main fault / shear zone.

Lithology

Lithology Comments

Dec 07, 2005 (S Fumerton) - The host is a fine to medium grained, siliceous granodiorite with blue quartz grains. Mafic minerals form up to 5% of the rock which is generally massive. Weak though pervasive carbonate alteration is associated with the shearing.

Mineralization

Mineralization Comments

Dec 07, 2005 (S Fumerton) - The quartz veining pinches and swells between 10cm and 50cm. Within the veins concentrated along the contact of the veins and in bands, less than 1cm thick, are disseminated grains or diffuse aggregates of fine to medium pyrite and chalcopyrite. Pyrite and chalcopyrite also occur is a similar mode in the granodiorite adjacent to the quartz veins. Within the granodiorite there are two types of pyrite mineralization. The more common disseminated subhedral grains and a less common variety where tarnished needles of pyrite occur as radiating needles (identification confirmed by XRD work). Sulphides with grains up to 5mm also occur in seams and thin veins within the braided shear zone. These veins locally have some sphalerite in addition to the pyrite and chalcopyrite. Along strike to the east the quartz veining narrows to a discontinuous seam with scattered quartz knots in the shear zone.

Date: Jul 28, 1954

Geologist: W Savage

Notes: Geo Moody, field geologist for N.A. Timmins Explorations placed a prospector and helper, W. Hyland and R. Auberton, in Chester township early in June 1954 and paid them a visit on July 27th. The writer flew in from Gogama by Department of Lands and Forests plane and joined Moody and his party. The original discovery (No. 1 Vein) on the Three Ducks Syndicate claim group was made by Alfred Gosselin in 1930. It can be seen in the east wall of a water filled pit located on claim S-20095(P) on the east shore of the north lake of the Three Ducks Lakes, about 300 feet north of the old Gosselin camps. The country rock is blocky jointed grey granite in which the strongest set of joints strike S80E and dip 75 to the north. Slight schisting on these joints was followed by the introduction of quartz stringers and sulphides to form the 'vein' which extends over widths of from 3 to 5 feet, and at one time was traced for 100 feet to the east.

Date: Aug 13, 1993

Geologist: S Fumerton

Notes: The original pit which is partially obscured by trees is 3 x 4m across and about 5m deep. Water fills the pit for about 2m. There is no sign of fencing around the pit or signs. Some flagging was put up on the blind side of the pit, loose blocks of ground surrounding the pit were scaled, and a rotten ladder in the pit was destroyed. The more recent trenching by Young Shannon is located to the east of the original pit.
