Point Location Description: Head frame on shaft.

Location Method: Field Visit with GPS

Access Description: Access to the shaft is easy from Highway 144 by taking the Mesomikenda Lake Road to the lake of the same name then an old mine access road leads from the lake to the mine around the Three Duck Lakes. Alternative access is possible from the Sultan Industrial Road in the south via the Chester Twp logging road. From this road tertiary logging roads connect with the old mine road west of the shaft.

Geology Comments

Dec 07, 2005 (S Fumerton) - The mineralization is hosted within a northeast trending shear zone. Within this shear there are a complex set of quartz sulphide veins - veinlets which have reportedly been deformed. The sulphide veins and quartz-sulphide veins also contain rounded fragments (milled) of quartz set in a fine to medium grained matrix. The matrix may be secondary quartz or massive sulphides. All quartz veins are fragmented.

Lithology

Lithology Comments

Dec 07, 2005 (S Fumerton) - Massive medium grained granodiorite to leuco granodiorite is the main lithological unit in the area. Other phases present are dioritic xenoliths, altered shear zones and quartz, carbonate, sulphide veins. Chlorite alteration is the most widespread within the shear zones and is more strongly developed where the shear zones cut through dioritic phases. Other alteration minerals include disseminated biotite, disseminated pyrite and veins of hornblende. Sericite and carbonate alteration has also been reported. The biotite occurs in both the dioritic and granodioritic phases as well as in quartz veins. Hornblende alteration - recrystalization occurs in small veinlets (<5mm) where the chlorite alteration is strong. Pyrite alteration is disseminated and variable in intensity though generally declining away from the shear zone axis.

Mineralization

Mineralization Comments

Dec 07, 2005 (S Fumerton) - Some very fine grained quartz veins as well as very coarse quartz veins occur in swarms within the shears. Individual veins are up to 20cm thick. Typical these quartz and associated sulphide veins and veinlets occur discontinuously along shears. In addition there is a 5m wide zone of sparsely disseminated sulphides within granodiorite adjacent to the mineralized veins. Molybdenite typically occurs in the sheared wall rock adjacent to the veins as relatively large flakes in the plane of the foliation. Visible gold has been reported in 'blebs' within the veins but gold mineralization is also associated with the disseminated sulphides in the shear zones adjacent to the veins. The mode of occurrence for the other minerals reported present in the deposit is unknown though the scheelite and tourmaline have only been found in trace amounts. N.B. The reported grade was derived from a selectively mined underground bulk sample whereas the strike length quoted refers more to the length of the shear zone which contains discontinuous mineralization. There is also some reference to three hanging wall and one footwall zones associated with the main mineralized zone.

Dec 07, 2005 (A Wilson) - At the time of discovery assays up to 85 g/t Au and 20 g/t Ag were obtained. One sample collected from the #20 Vein by the Martin Syndicate returned a value of 570 g/t Au. A 7 kg bulk sample with visible gold, collected by Young Shannon Gold Mines returned a value of 30 g/t au, 1.7 g/t Ag. An average grade of 12 g/t Au across 1.2 m was obtained during diamond drilling conducted by Young Shannon in 1937. Grab samples collected in 1978 returned values of 1.7 g/t au; 0.34 g/t Au; 6.17 g/t Au; 2.06 g/t Au.

Oct 20, 2022 (Sheree Hinz) - The Gosselin deposit is located approximately 1.5km northeast from the Côté deposit. Mineralization lies within the hydrothermal breccia, diorite breccia, and tonalite units. Both the Gosselin deposit and the Côté deposit are classified as intrusion related disseminated gold deposits.

Date: Jul 28, 1954

Geologist: W Savage

Notes: Geo Moody, field geologist for N.A. Timmins Explorations Ltd 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 on July 28th. The N.A. Timmins camp was located on the south shore of the southeast bay of the north lake of the Three Ducks Lakes. The shaft is located near the shore of the south bay of the west arm of the north lake, about 600 feet southeast of the outlet from Cote Lake, on claim S-19971. The three foot wide quartz vein on which the shaft was sunk can be seen in old trenches east and west of the shaft. (The Three Ducks Syndicate's No.4 showing, not included in Laird's reports). In the west trench the vein strikes N70E and dips 60 to 70 to the south. It occurs on the contact between white to grey weathering granite (alaskite?) to the north and biotite schist to the south. The shaft was sunk on the vein and is inclined 70 to the south. It appears to have run out of the vein since the dump is predominantly rock. The hanging wall rock is coarse crystalline hornblendite.

Date: Dec 07, 1977

Geologist: L Tihor

Notes: A one day visit was made to the Erana Mines Limited gold prospect in west-central Chester Township. The writer was accompanied by Paavo Kivsto, District Mining Engineer, and Clarence Frost, Mine Safety Inspector. The property is owned by Ed. Blanchard of Sudbury. But, at the time Blanchard was not available and we were given permission to examine the property by Ron Dillabough, general foreman. We found one shaft with levels at 100 and 200 feet. The 200 foot level was inaccessible due to flooding. It appears that the 'Keewatin volcanics' are hydrothermally altered portions of the granodiorite flanking the shear zone. The mineralization zone itself, averaging about 2m in width is a complex zone of shearing and brecciation with myriad small veinlets of calcite, quartz and sulfides. There are occasionally distinct veins up to 50cm wide consisting of quartz or calcite or a combination of these with or without sulfides. These veins parallel the plane of shearing and strike N80E and dip 50S. The sulphides are predominantly pyrrhotite, with minor amounts of chalcopyrite and pyrite. Although the assessment files are generously sprinkled with reports of very high gold assays and visible gold, no v.g. was found during this visit. [ PRECIS ]

Date: Jun 30, 1980

Geologist: L Lutha

Notes: The principal American financiers for Canadian Crest Gold Mines have suspended operations in June at their property in Chester Township pending an investigation. The Resident Geologist accompanied Walter Hayduk and Stan Barron from New Jersey and recommended that they do a complete re-evaluation of the property (sampling, new ore reserve calculations and feasibility studies). In the residents geologist's opinion previous work and interpretations may not be reliable. Since the visit new staff have been hired and work is to start soon. [ PRECIS ]

Date: Jul 27, 1993

Geologist: S Fumerton

Notes: A brief visit was made to the site. The buildings, a cabin, a bunkhouse, a garage, a core shack, and a hoist house are in a moderate state of repair. The steel headframe is still intact with skip plus wire rope attached, though the siding around the headframe has been removed. The single compartment shaft is covered with 2x6' lumber weighted down with the skip and steel railings. However, a manway equipped with a sturdy ladder is only covered with loose plywood though the shaft is flooded to within 3m of the collar. This loose access was mentioned to an affiliate of the owner who gave assurances that the access would be secured right away. The single drum compressed air hoist is intact and last licensed in 1978 but no air compressor is on site. The mill has been demolished. Recent drill core is stored outside on steel racks and is generally in good order. An attempt was made to locate the original Three Ducks Syndicate #2 vein south of the Young Shannon headframe. Though there is now a system of drill roads, washed outcrops etc in the expected area, no sign of any old trenching or quartz veining was found. Laird's (1932) description of a north dipping vein system to original discovery is at odds with the south dip of the Young Shannon deposit suggesting that they are distinct prospects. As no one has relocated the original workings they has been a tendency to regard the Three Ducks #2 vein as the same as the Young Shannon deposit.
