Point Location Description: General

Location Method: Based on Assessment

Access Description: The mine is located 47 km south of Dryden, 400 m east of Carleton Lake, on the south side of a broad swamp. The property is accessible from Manitou Straits. The Queen Alexandra mine consists of one shaft and one exploration pit, 65 metres apart, and seven trenches (figure 13). The occurrence exposes two conjugate quartz veins. (OFR 5731, p. 105; 1989)



Exploration History

1904: An English syndicate sunk a shaft 85 feet, and milled 18 tons of ore, producing gold valued at $16 to the ton (16.6 ounces of gold)

Mineralization Comments

Feb 22, 2010 (C Ravnaas) - Sample near the shaft returned up to 28.8 grams per ton Au are reported in Bond Gold assessment file 52F07SW FF2. The mine is underlain by mafic volcanic rocks of the Blanchard Lake group (Blackburn 1976, 1982). Shearing at the shaft strikes 080°, whereas shearing at the exploration pit strikes 030°. Both shears contain a quartz vein. The sheared rocks are weakly schistose and altered to chlorite-carbonate schists. Both shears are of unknown width, and dip vertically. Kinematic indicators, such as the Z-shape of the vein 2, suggests a dextral strike-slip component of movement on the shear at the exploration pit. The differing strike of the two shears suggests conjugate shearing (Figure 13). The quartz carbonate vein (vein 1) at the shaft is 10 cm wide and exposed over a 2 m length, is pale to dark grey, opaque, and contains ribbons of pyrite and chlorite. Patches of pink calcite and chlorite occur in the vein material. 2-5%, very fine to coarse grained pyrite is present in the vein. The amount of quartz material in the dump suggests that the quartz vein is probably wider at depth in the shaft. The quartz vein (vein 2) at the exploration pit pinches and swells, but averages 45 cm in width and can be traced over 23 m in length. The quartz is white to pale grey, is opaque, and fractures are filled with calcite. The vein has a laminated and wispy texture due to ribbons of pyrite and chlorite. One per cent medium grained pyrite is present in the vein. Nine grab samples were taken by the author (Table 16). Gold occurs in the quartz vein, but appears to be low in the schist. Analytical results indicate a correlation between amount of gold and copper and zinc. (OFR 5731, p. 105-109; 1989)
