Exploration History

1910 Powell Company sunk 2 shaft, test pits etc. (2nd shaft located 2600 ft. to east of this location.). 1919 to 1925 prospected by John A. Mcpherson. 1938 property exam by Erie Canadian Gold Mines Ltd. 1939 Irvin Porcupine Gold Mines Ltd. drilled 4 ddh in the vicinity of the No. 1 shaft. 1967 Property held by R.E. Allerston. 1984 Puissance Mining Corp. completed Mag and VLF surveys over a large group of patented claims, stripped, washed, mapped and sampled a 2000' long trench and drilled 10 diamond drill holes, 2 of the drill holes tested in the vicinity of the No. 1 shaft. 1985 Puissance Mining Corp excavated 8 bulk samples totaling 161 tonnes. Seven of the samples were of the carbonate zone while 1 bulk sample was extracted from the iron formation. Two adjacent samples of the 7 bulk samples on the carbonate zone returned 5.1 g/t Au and 2.1 g/t Au respectively. The remaining 5 samples returned less than 1 g/t Au. The iron fromation sample returned 2.2 g/t Au. The average of all samples was 1.9 g/t Au. Further bulk sampling was planned for 1986 and there is field evidence for this sampling having taken place, but no record of the results were released.

Geology Comments

Dec 07, 2005 (G Seim) - This occurrence is situated within Deloro assemblage rocks about 2300 m SE of the Destor-Porcupine Fault Zone. The no. 1 shaft is located near the western end of a 1200 m long by 15 m wide carbonate-quartz-mariposite (fuchsite) alteration zone, hosted by mafic metavolcanic rocks (flows and fragmetals) with thin interlayered iron formation. The alteration zone strikes 270/60. From Burrows 1911: The claims of the Powell group are in the northeast part of Deloro township. A band of rusty weathering carbonate with much serpentine occurs on M.E. 22, M.E. 21 and adjoining claims. This band has a strike somewhat south of west, varies in width from 35 up to 75 ft. and dips to the north at about 60. In parts of this band there are veinlets of quartz and dolomite in which visible gold has been found. The veinlets of quartz have a general strike of northeast and southwest. In one part argentite occurs in association with the gold. Two 50 foot shafts one-half mile apart have been sunk in the hanging wall of the carbonate band at points where the rock is much intersected by quartz veins.

Mineralization Comments

Dec 07, 2005 (G Seim) - 1939 Diamond Drilling by Irvin Porcupine Mines Ltd. intersected values up to $16.80 per ton over 2 ft. in mineralized iron formation and $1.40 over 1 ft. from a quartz vein in the carbonate zone. Gold was $35.00 per ounce. 1985 Puissance Mining Corp excavated 8 bulk samples totalling 161 tonnes. Seven of the samples were of the carbonate zone while 1 bulk sample was extracted from the iron formation. Two adjacent samples of the 7 bulk samples on the carbonate zone returned 5.1 g/t Au and 2.1 g/t Au respectively. The remaining 5 samples returned less than 1g/t Au. The iron fromation sample returned 2.2 g/t Au. The average of all samples was 1.9 g/t Au.



Alteration Comments

Dec 07, 2005 (G Seim) - Ankerite-quartz-fuchsite forms the main alteration zone while sulphidation is present in the iron formation.

Notes: This prospect was examined on October 18th 2002. The carbonate zone is exposed in a series of trenches/stripped areas for a length greater than 1000 m. The carbonate zone trends 270 through amygaloidal mafic metavolcanic flows and related breccias, some felsic volcaniclastic rock, and iron formation. The carbonate zone appears to cross cut local stratigraphy. This is especially apparent where the zone perpendicularly cuts an iron formation about 300 m east ot the No. 1 shaft. Diamond drilling of the carbonate zone suggests that it dips about 60 to the north. Several sets of quartz veins cut the carbonate zone, some extending into the adjacent wall rock. The dominant set of quartz veins fill tension fractures perpendicular to the strike of the zone. These fractures are typically steeply dipping. Other quartz veins fill fractures at various orientations with dips typically 60 degrees or shallower. There is also a flat vein set. Sulphide mineralization consist of pyrite and chalcopyrite, but galena has also been reported. About 300 m east of the no. 1 shaft a north striking band of jasperoidal iron formation is cut be the carbonate zone. The iron formation is highly fractured near to the carbonate zone, the fractures filled with several generations of quartz. The iron fromation is sulphidized where it is cut by quartz veining. The intrensity of the sulphidization rapidly decreases away from the veins. The carbonate zone is predominantly ankerite or ferroan-dolomite with minor quartz and fuchsite, the latter suggesting that the protolith might have been ultramafic. The mafic metavolcanic rocks adjacent to the carbonate zone locally are pervasively altered by an iron carbonate. The no. 1 shaft, was located using a gps to withing 5 m accuracy.
