Point Location Description: Folded quartz albite vein near the north end of the stripped area.

Location Method: Field Visit with GPS

Access Description: Access is relatively easy as a 3 km long secondary drill road branching off the Kenogaming Main Haul Road passes close to the trenches and stripped area. However, a beaver pond covers the secondary road about half way down and an old culvert under the road bed in the beaver pond has been damaged.

Exploration History

1957: Canadian Johns-Manville Co. Ltd. – GL.1972: J. Johnson and A. Wright carried out magnetic and electromagnetic surveys which covered the area. 1982: Gold Field Resources carried out magnetic and VLF-EM surveys over the showing. 1984: R. Tremblay carried out a trenching program over two years to expose bedrock in the area of the showing. 1987: Glen Auden entered into a joint venture with Goldrock Resources to undertake a large exploration program. Initial work consisted of a lithogeochemical survey and a reconnaissance mapping program on ground peripheral to that mapped in 1986 which lies to the southwest of the showing. In the following year the property was covered by a number of magnetic surveys. In addition to this, samples collected in 1987 while mapping were analysed for their whole rock and trace element composition and the results were reported in 1988. Stripping was carried out in this year (Trench 18) in order to open up the ground previously trenched. Samples collected from a pyritic vein ran as high as 0.2 g/t Au. 1989: American Barrick Resources optioned the property and carried out a sampling program centred on this showing which returned values up to 3.14 g/t Au. This was followed with three drill holes (192m) which failed to duplicate the surface results. 1996-1997: Sewell Mining Corp. – IP, Mag. 2011: Benton Resources Corp. – Assays, DD – 8 – 1477m, GL, Lc, Pr, IP, Mag.

Geology Comments

Dec 07, 2005 (S Fumerton) - The mineralization occurs in a banded zone oblique to the foliation / schistosity. This schistosity has numerous small to moderate sized 'Z' folds, centimetre to metre scale, which are locally highlighted by discontinuous quartz veinlets. The banded mineralized zone also has 'Z' folds and the axial planar cleavage to these folds is 295/70 and the folds in the mineralized zone plunge at 55 towards 307.

Lithology

Lithology Comments

Dec 07, 2005 (S Fumerton) - The host rock is a chlorite, carbonate schist which locally has undergone recrystallization and the grown of hornblende porphyroblasts which has obliterated the schistosity. This recrystalization has taken place in bands parallel to the schistosity. The showing is cut by numerous mafic dykes up to 1m in thickness which are lamprophyric. There are also two larger granitic dykes up to 5m thick. One is coarse grained with small feldspar megacrysts, opalescent quartz grains, together with sericite and some hornblende needles. The other granitic dyke has blue quartz and pink feldspar megacrysts (<5mm) and contains hornblende as the mafic mineral. The alteration in the outcrop is strong and pervasive though intense alteration does occur in patches.

Mineralization

Mineralization Comments

Dec 07, 2005 (S Fumerton) - Mineralization occurs in a banded altered zone together with an axial quartz vein. The banding occurs on a millimetre to centimetre scale and consists of iron carbonate, tourmaline, sericite, and chlorite rich bands over a thickness of 1 to 2m. The axial vein has a highly irregular shape is discontinuous and varies between 10 and 20cm thick. The vein is composed of quartz, albite, and tourmaline, with the tourmaline crudely concentrated along the margins. Both the axial vein and the banded alteration zone are cut by small secondary quartz veins. Other smaller quartz albite veins occur in the vicinity of the main vein described above. Pyrite is the principle mineral and occurs as fine to medium grains partially concentrated in the chloritic bands. Pyrite also occurs together with some arsenopyrite in larger grains within the axial vein.

Dec 07, 2005 (A Wilson) - Samples collected from a pyritic vein by Glen Auden Resources in 1987 returned assays of 0.2 g/t Au. American Barrick (1989) obtained values up to 3.14 g/t Au from this occurrence. Grab samples collected by the OGS in 1992 returned 0.13 g/t Au, 0.31 g/t Au, 0.07 g/t Au.

Mar 15, 2016 (P Bousquet) - In 2011, Benton Resources Corp. collected 38 samples from various locations on the shear zone. 16 samples returned values between 0.15 and 0.92 g/t gold and 10 samples returned values between 1.39 and 5.09 g/t gold (T-6394). The company also drilled eight holes in the vicinity. The best intersection returned an assay of 94.02 g/t gold over 1.1 m (Hole SW11-03, T-6394). The sample was composed of an albite and sericite altered mafic volcanic with 5% fine pyrite.
