Point Location Description: Veins
Location Method: Conversion from MDI
Access Description: The northeast corner of North Bay may be accessed by suitably equiped light aircraft in summer and winter. Boat access to Sturgeon Lake is easiest from Hwy. 599 at Trappers Point approximately 4 km south of the CNR mainline at Savant Lake station. The Number 1 Vein is located approximately 1 km east from the junction of two trails shown on OGS Map 2431, Beckington Lake. The area can be reached from the Beckington or Camp 700 road located 1.5 km south of the railway tracks at Savant Lake village. The road trends east for 1 km and then turns south for 3 km. At the first fork in the road continue south by a large sand pit and gravel airstrip to the intersection with a west trending trail. Depending on the weather, the type of vehicle and time of year it may be possible to drive or walk 2.5 km southeast to the area where the North Bay occurrence is located on the east side of the trail. A marker may be located to indicate the trail to the site.
This area was first prospected and explored between 1900-1910 when construction of rail lines allowed easy access to Sturgeon Lake. The earliest mention of exploration around North Bay of Sturgeon Lake is included in the Report of the Bureau of Mines, 1901. T.W. Gibson reported on exploration in the Sturgeon Lake area (T.W. Gibson, 1901). Mr. Gibson included a report by developer H.D. Symmes which discussed the geology of the BG 155 to BG 158 claim group. Moore (1911) briefly mentioned a shaft east of Claim HW 691 near the north end of North Bay of Sturgeon Lake. A 53 foot deep shaft had been sunk on an irregular quartz vein in greenstone. South of the shaft a large pit had been excavated in an irregular mass of quartz. Moore (1911) had not visited the area and his location was uncertain. From 1910 to 1935 little if any exploration activity was carried out in the North Bay area. Most of the exploration activity was centred at the St. Anthony Mine, the King Bay area and the North- east Arm of Sturgeon Lake. Between 1938 to 1939 Classic Sturgeon Gold Mines Ltd. staked a block of claims on the northeast shore of North Bay. From 1940 to 1942 Classic Sturgeon Gold Mines Ltd. staked and examined a claim block to the west of the Ouillette Lake and Thomas Lake area. This new block covered the east shore of North Bay south to claim BG 159 and extended approximately 2 km to the east.
Dec 07, 2005 (R Tuomi) - The North Bay occurrence is located approximately 150 m to the east of the trail on a 2 to 4 m 160 degrees trending rise. The area has been cleared of trees to a diameter of 10 to 15 m. A shaft approximately 4 m by 3 m is lined with split logs to below the water level which is 2 to 3 m from surface. The appearence of the log lining suggests it has been replaced at least once in the last 90 years. Several lengths of rusty 1 inch metal piping found on the shaft site suggest that the area has been examined, and probably upgraded, between 1935 and 1940. The shaft seems to have been sunk, lined by wood and then been supported by backfill gravel, most of which may have been obtained from the shaft. The exposed rock is a fine grained meta-basalt with quartz partings and thin veinlets dipping shallowly to the east. One sample of the more quartz flooded material returned an assay of 0.03 ounce gold per tonne. This sample may not have been in place. One other sample from the shaft area assayed a trace of gold. Approximately 200 m southeast of the North Bay shaft a short trench 10 m long by 5 m wide was found and sampled. The trench long axis is 070 degrees and cuts through mafic metasediments or fine grained meta-basalt. The rocks dip 50 degrees to 60 degrees to the northeast and up to 10 % of quartz veins replace the mafic rocks parallel to the dip. 1 to 2 % of pyrite and chalcopyrite are present in the quartz veins. Two samples were assayed for gold. One of the samples assayed trace gold (DAJ95-NBS-S).
