Primary Commodities: Iron
Secondary Commodities: Gold
Township or Area: Heenan
Latitude: 47° 46' 5.93" Longitude: -82° 22' 37.39"
UTM Zone: 17 Easting: 396820 Northing: 5291468 UTM Datum: NAD83
Resident Geologist District: Timmins
NTS Grid: 41O16SW
Point Location Description: Precise, drillhole collar transferred to Dwg 108, T-2311
Location Method: Data Compilation
Access Description: Easy access to the area is now possible via a secondary forestry road that extends east from the Heenan Township road. This access road in turn connects with the Dore road just north of the Wakami River.
1906-07: Messrs. Leith and Van Hise staked the property, carried out a dip needle survey then performed extensive prospecting, trenching and sampling. The majority of trenching was carried out on patented claim W.S. 8. In the same year a survey was made of water falls on the Woman River as possible power sources. Algoma Ore also sampled and evaluated the iron formation. (GR 38, p. 46, T-4274). 1946: Fummerton Mining and Development completed ground geophysics and geological mapping on claims north and NE of Claim W.S. 8. (T-2106). 1959: W.G. Wahl acquired the ground from an estate but no exploration was carried out. 1961: A. M. Goodwin (ODM): sampling, concentration tests (GR 38, pp. 50-51). 1965-66: W.G. Wahl carried out mapping and a ground magnetic survey over the iron formation then extracted a bulk sample from several test pits. Beneficiation tests indicated that an acceptable concentrate could be produced from the -325 mesh (T-2311). 1975-1976: U.S. Steel International / W.G. Wahl / Essex Minerals: ground geophysics, geological mapping, sampling, geochemistry (in SW and SE corners of WS8; work was reported but not all results are on file); 2 drill holes collared east of Anomaly 7. Due to the fine-grained habit of the magnetite, it was determined that extraction of an acceptable concentrate would require a fine grinding circuit so the project was abandoned (T-2311). 1991: G.M. Archibald carried out reconnaissance mapping (T-3661). 2005-2006: VenCan Gold Corporation carried out ground and airborne geophysical surveys (T-5328, T-5418); reconnaissance sampling on WS 8 (T-5561).

Feb 10, 2010 (S Fumerton) - Northwest trending faults have separated the iron formation into a number of distinct zones.

Dec 07, 2005 (S Fumerton) - The iron formation is composed of chert, jasper and magnetite with siderite and pyrite locally. The horizon is underlain by felsic volcanics and overlain by mafic volcanics. The iron content is notably higher at the base of the iron formation in contact with the felsic volcanics.
Feb 10, 2010 (D Draper) - Intense folding in the area has drag-folded and shortened the formation with the magnetite bands becoming schistose and the chert layers brecciated. (AR Vol 41-3, p. 48)

Feb 10, 2010 (D Draper) - The iron formation in Leith Zone 2 is composed of chert, jasper and siliceous magnetite with minor siderite and pyrite locally. Zone 2 is approximately 400 feet wide and 1500ft long, averaging 26.3% Fe, 0.013% P, and 1.18% S, with local areas up to 43% Fe. (GR 38, pp. 49-51) Wahl sample #419 (banded chert with magnetite IF, taken near Anomaly 7 in the SW corner of Patent WS 8) returned 38.8% Fe. Drillhole WR-2-76 was collared 150m east of the sample location, bearing az310 deg. The average head analysis for this hole was 27% total Fe. (T-2311) [Note: locations of the original trenching by Leith are not on file. However, a circa-1907 map of WS 8 indicating Leith's Main Ore Bearing Zone shows Wahl's later drilling to be within its vicinity. (T-4274)] Vencan grab sample 7748, taken approx 215m north of Wahl's drillhole location, returned 446ppb Au; no description of sample given. (T-5561; sample coord - 396791E, 5291681N)
