Point Location Description: Trenches
Location Method: Data Compilation
Access Description: A point 3.54 km south and 7.16 km east of the northeast corner of Michaud Twp. Access to the quartz veins may be made to within a few hundred metres via sand roads accessible from Highway 101; the remaining distance must be traveled by foot through open bush.
1937- 1938: A geophysical survey was completed and 11 holes totalling 4,838 feet were diamond drilled in central Michaud Township (Satterly 1949). 1939: Michaud Porcupine Gold Mines Ltd. was incorporated and eventually acquired a contiguous block of 67 patented claims in central Michaud Township (Satterly 1949). 1946: By this time, quartz veins hosted by felsic intrusive rocks had been trenched and pitted (Satterly 1949), diamond drilling by Michaud Porcupine Gold Mines and Anglo-Huronian Ltd. had been completed, but '...no gold values of economic importance [had] yet been found...' (Satterly 1949, p.23). 1996: Battle Mountain Canada Inc. completed 2 diamond drill holes totaling 340 m in claim L.803909, SW 1/2 of S 1/2 of Lot 9 Concession 5. The best assays in hole PL96-1 were 690 ppb gold over 1.50 m and 670 ppb gold over 1.50 m. The first intersection was in silicified pillowed flows and the second was in breciated syenite.
Dec 07, 2005 (C Salo) - Geological mapping (Satterly 1949; Baker et al. 1980; Jensen 1989, 1985; Jensen and Langford 1985; Jensen and Baker 1986; Johnstone and Steele 1989; Troop 1989) indicates that felsic rocks which host the quartz veins are part of a large, largely glacial drift covered (Baker et al. 1980; McClenaghan et al. 1988, 1987; Steele 1988) irregularly shaped stock which intrudes weakly metamorphosed (greenschist or lower metamorphic facies except marginal to intrusive felsic rocks where narrow contact metamorphic aureoles of amphibolite grade are developed) ultramafic to felsic subaqueously deposited volcanic rocks of the (Archean) Stoughton-Roquemaure Group. The felsic stock is several hundred metres north of the east to east northeast striking Main (or Southern) Branch of the Porcupine- Destor Fault Zone (locally termed the Munro Fault Zone). Volcanic rocks intruded by the felsic stock strike west northwest to east northeast, dip steeply, and face north. Intrusive rocks in addition to the felsic stock which occur in the area include narrow (generally tens of metres in width) north striking diabase dikes of the (Proterozoic) Matachewan swarm (Heaman 1989) and narrow (metres in width) lamprophyre dikes. A recent geophysical survey of Michaud Township (OGS 1984) failed to detect any anomalous bedrock conductors near the quartz veins.

Dec 07, 2005 (C Salo) - Mineralization observed by Bath (1990) at the Michaud Porcupine occurrence consists of quartz-pyrite-(tourmaline)- (molybdenite(?))-(galena(?)) veins hosted by magnetic pink syenite. Anomalous gold tenors (assays from the area obtained by the present writer ranged from nil to 4,200 ppb of gold) occur in the area. The highest gold tenors are associated with quartz-tourmaline-sulfide veins. The lack of significant identifiable alteration associated with these quartz veins and their small size suggest that the occurrence has limited potential to host economic gold mineralization. Such vein systems, however, if developed in a larger and more continuous form, could host potentially interesting gold tenorsAnalyses*: AB-86-194 nil Au ppb, 14 Cu ppm, 14 Pb ppm, 23 Zn ppm, 3 Mo ppm; AB-86-195 3,770 Au ppb, -- Cu ppm, -- Pb ppm, -- Zn ppm, --- Mo ppm; 4,660 Au ppb, -- Cu ppm, -- Pb ppm, -- Zn ppm, --- Mo ppm; AB-86-196 30 Au ppb, 19 Cu ppm, 34 Pb ppm, 24 Zn ppm, 13 Mo ppm; AB-86-197 1,070 Au ppb, 19 Cu ppm, 61 Pb ppm, 71 Zn ppm, 152 Mo ppm; AB-86-200 10 Au ppb, -- Cu ppm, -- Pb ppm, -- Zn ppm, --- Mo ppm; AB-86-201 3 Au ppb, -- Cu ppm, -- Pb ppm, -- Zn ppm, 269 Mo ppm; AB-86-202 340 Au ppb, -- Cu ppm, -- Pb ppm, -- Zn ppm, 85 Mo ppm; 340 Au ppb, -- Cu ppm, -- Pb ppm, -- Zn ppm, --- Mo ppm; AB-86-203 30 Au ppb, 23 Cu ppm, 9 Pb ppm, 3 Zn ppm, 2 Mo ppm; AB-86-204 70 Au ppb, 27 Cu ppm, 85 Pb ppm, 21 Zn ppm, 84 Mo ppm; AB-86-205 40 Au ppb, 26 Cu ppm, 137 Pb ppm, 47 Zn ppm, --- Mo ppm *All assays performed by Swastika
