Point Location Description: Mineshafts, stripped areas, trenches, diamond drill sites.

Location Method: Conversion from MDI

Access Description: The property (site of the original workings) is situated 3.2 km east-northeast of the town of Beardmore, near the southeastern boundary of Summers Township. The Canadian National Railway line bounds the claim group on the north, and the Pancontinental property immediately adjoins the Spooner-Norex ground to the west. The main showing on TB4815 is reached by following Highway 11 to a point just north of the Beardmore townsite and travelling east along a gravel road for 1.6 km to the Pancontinental GOMILL site. By following the railway tracks eastwards on foot for 1.3 km, the shaft area is easily accessible to the south.

Exploration History

1925: F. Spooner staked a group of 9 claims approximately 3 km east-northeast of the Beardmore townsite. 1927-34: Considerable stripping and trenching was conducted over 3 vein systems--the Power vein, the Contact vein and the 'A' vein. The Power vein is a continuation of the main production vein at the Northern Empire Mine to the west. 1935: Spooner Gold Mines Ltd. was incorporated in Toronto with H.T. Leslie as President and F. Spooner as director. A 3-compartment shaft was sunk on the Power vein near the centre of the property. It was abandoned at 12.2 m when no vein material was encountered. 1936: A second 2-compartment shaft was sunk on the Power vein at an incline of 80 degrees south. Drifting and cross-cutting were carried out. The Northern Miner (Oct. 1936) reported that an 18.3 m oreshoot was exposed on the first level. 1937: Underground development continued. 1,669 m was diamond drilled. Claims totalled 15. 1939: Norex Mines Ltd. was incorporated in Toronto and took over the property and the assets of Spooner Gold Mine Ltd. An agreement was reached with the Northern Empire Mine to extend their drift on the 525.8 m level into the Spooner property. 1940-41: Encouraging values across narrow widths were encountered but no oreshoots were found. Operations ceased by mid-year. 1947-1978: Leases renewed; claims transferred; leases expired; ground restaked. 1979-80: A Hopkins performed power stripping, geochem sampling and diamond drilling. 1981-83: Pancontinental Mining Ltd. did linecutting, EM, mag and VLF. 1987: Parklane Technologies Inc. conducted magnetometer and EM-16 geophysical surveys, trenching, and drilled 10 DDH totalling 1251.81 m. 1988: Parklane Technologies Inc. drilled 6 DDH totalling 505.66 m. 1997: Goldmint Exploration Ltd. drilled 2 DDH totalling 1105.2 m.

Geology Comments

Nov 04, 2019 (B Nelson) - The property lies entirely within the most southerly unit of the Wabigoon Sub-province near its boundary with the Quetico Sub-province. This intermediate to mafic metavolcanic sequence (southerly unit), which forms an east-trending lenticular belt up to 3 km wide, consists of massive, pillowed and amygdaloidal flows (clhlorite schists), mafic tuffs, felsic to mafic intrusions, and/or coarse flow rocks. Paralleling the metavolcanics, both to the north and south, are Archean metasediments, consisting predominantly of greywacke, with siltstone and argillite. Pillow structures suggest younging to the north.

Lithology

Mineralization

Mineralization Comments

Nov 04, 2019 (B Nelson) - Three main vein structures are known to exist in the area. The Contact vein strikes 070-080 degrees, is generally conformable to the surrounding highly schistose bedrock, and averages up to 1.5 m in width. It has been traced for over 450 m. The Contact vein is characterized by well defined stringers of pyrite and chalcopyrite parallel to the siliceous banding in the vein, with lesser amounts of arsenopyrite, chalcopyrite and tourmaline. A few channel samples of the decomposed surface of the Contact vein gave low values, with the exception of one sample, taken at 836 feet, which gave $4.40 (Au @ $20/oz) over 1 foot of quartz. The Power vein is conformable to the enclosing metavolcanic host rocks and strikes N69 degrees 55 minutes E, with an average dip of 80 degrees S. Over the greater part of its length the vein is highly weathered and decomposed, with the surrounding host rocks exhibiting a highly schistose nature. In places the overall width reaches 9.1 m. The vein is not as lenticular as on the Northern Empire ground but has greater continuity and width on the Spooner property. H.T. Leslie believed the Power vein to be a remnant of a siliceous phase of a banded iron formation. Mineralization in the Power vein is primarily pyrite and pyrrhotite with lesser amounts of chalcopyrite and arsenopyrite. In places along the vein, pyrite and pyrrhotite are massive, especially near the wall rock contact. Occasionally, minor galena and rare coarse visible gold were encountered in some pits. H.T. Leslie (1935) reported that the Power vein, other than providing many showings of visible gold, had erratic values up to $5 and $6 per ton on the old $20 gold basis. A vein exposed underground (presumably the Power) is reported to contain 0.42 oz/ton Au across 0.51 m. The A vein is located 281.6 m south of the Power vein and has the same strike and dip. The quartz and mineralized schist associated with it make up a width of 1.07 m to 1.52 m. It is badly weathered and in place heavily stained by red iron oxides to a depth of 0.20 m on the edges of the vein. No sampling was done over the A vein, which was found to be very similar to the Contact vein in character. Four other veins or vein systems are known to exist on the property. Although underground development was conducted both on the property and from the 525.8 m level of the Northern Empire shaft, no production was ever recorded from the Spooner-Norex property (Mason and White, 1986).

Nov 04, 2019 (Therese Pettigrew) - Sample 83-MSN-2 collected by OGS staff returned 0.18 oz/t Au (6.17 g/t Au) from a sugary to vitreous quartz-carbonate vein in sheared, green andesitic to basaltic metavolcanics with chlorite-sericite alteration (Mason and White, 1986). DDH SP88-1 returned up to 1.45 g/t Au over 0.8 ft and 1.46 g/t Au over 2.0 feet. DDH SP88-5 returned up to 1.44 g/t Au over 1.1 feet. DDH SP88-6 returned up to 0.63 g/t Au over 1.7 feet (Assessment report 42E13SW0001). DDH SP-2 returned up to 4.15 g/t Au over 0.5 m (Assessment report 42E12SW2001).
