Resident Geologist District: Thunder Bay North
NTS Grid: 42E10NE
Point Location Description: Trenches and diamond-drill holes.
Location Method: Conversion from MDI
Access Description: The property is located in the McBean Lake area, 2 km east of Long Lake, or 3.4 km to the northwest of McBean Lake. The property is accessible by travelling highway 11 for 9.5 km east of the turn-off to Geraldton (Hwy 584) and then travelling southeast on Eldee Lake Road to Long Lake. Continue northeast of Long Lake for approximately 8.5 km to Birch Bay, and east to the shore of the lake. From this point, proceed eastward on foot for approximately 2 km.
1936: Surface exploration conducted on claims staked by M. Simmons and Lorne Hawke. 1938-40: 146 assessment days credited to each claim, now in the control of Alexander Longwell. 1944: Claims surveyed and patented by Coniagas Mines Ltd. Patents later revoked. 1970: Some of the claims restaked and transferred to Canadian Nickel Co Ltd. 1971: 2 holes drilled (90.8 m) south of the original-seven claim block. 1979: Claims restaked as part of a much larger claim block. Claims were then transferred to Shell Canada Resources Ltd, which conducted an airborne mag survey. 1982: Claims cancelled, then restaked by Mike Malouf. Coniagas trenches were sampled by Eldorado Nuclear Ltd. 1984: A grid was cut over the Malouf property, and mag and EM surveys were conducted. Power stripping was also performed elsewhere on the claim block. Michael F. Cowan conducted mag and geological surveys on his claims. 1986: As of 1986, the majority of the original claims are held by Michael Malouf and are part of a 36 claim block held by a newly formed public company called Ferau Resources Inc. The remainder of the original claims are held by Michael F. Cowan.

Dec 07, 2005 (B Nelson) - The showing consists of an altered greywacke band 10 to 15 m wide enclosed by coarse hornblende schist and gneiss. The host unit has been described as a medium to coarse-grained, moderately deformed quartz hornblende schist. The southern portions of trenches 3 and 4 appear to be metavolcanics as opposed to metamorphosed pelitic sediments, i.e. the QHS unit. The sediments exposed on these properties tend to be finer-grained than those seen in the Geraldton camp i.e. a dominance of metapelites and the fine-grained mafic sediment precursor to the QHS, as opposed to wackes and arkoses. This may reflect upon original sedimentary facies--possibly a more distal depository. The grade of metamorphism is markedly higher than that found in the sedimentary package 8 km to the west, where upper greenschist facies prevails. On these properties, the lithologies have undergone amphibolite facies grade metamorphism, possibly resulting from the proximity of a large felsic intrusion.

Dec 07, 2005 (B Nelson) - Irregular and possibly discontinuous sulfide, quartz, and carbonate lenses, 1-2 m wide, which cross-cut foliation and hence, are later than the major phase of deformation, form the dominant style of mineralization in the Coniagas trenches. Well formed acicular laths and coarse prisms of arsenopyrite are the outstanding mineralogical feature in these trenches. Arsenopyrite is found as vein selvages and disseminated throughout the iron-stained quartz hornblende schist. Sulfide content in the sediment, of both arsenopyrite and pyrrhotite, may approach 3% in some lenses. Coniagas Mines trenched and sampled the showing for some 61 m. Gold values were reported as 'fair but erratic.' A sample from #4 trench yielded a value of 0.106 oz/ton Au over a width of 0.91 m.
