Point Location Description: Transfer
Location Method: Conversion from MDI
Access Description: The claims are situated in the Manitou Lakes area, Kenora Mining Division, Ontario, and occupy portions of claim map area G-2683 (Lower Manitou Lake), G-2572 (80yer Lake), and G-2584 (Harper Lake) in N.T.S. map area 52-F-7. Winter access into the area from Highway 502 is via a 5km long skidoo trail into the settlement of Gold Rock. The trail leaves Highway #502 approximately 50km south of Dryden, Ontario. Summer access is via float plane or by boat from Cedar Narrows, approximately 80km to the south. The skidoo trail into Gold Rock is passable using ATC's but is not suitable for hauling boats.

Nov 23, 2009 (D Scholtz) - The geology of the Manitou Lakes Property has been described in detail by the writer in an earlier report dated November, 1985. The "E" and "F" zones are located on a 1 km wide peninsula which separates Manitou Straits from the main body of Upper Manitou Lake. The peninsula is underlain by a northeasterly striking, southeasterly dipping sequence of interbedded mafic and intermediate flows and tuffs. These rocks lie in the southeasterly limb of the Manitou anticline and trend directly into correlative and equivalent lithologies in the Gold Rock camp, two kilometres to the north, which host the Big Master and Laurentian mines, two of the Kenora Mining Division's three former producing gold mines.
Feb 24, 2010 (C Ravnaas) - Archean volcanic and sedimentary stratigraphy in the Manitou Lakes area is typical of the greenstone belts of Wabigoon Subprovince. In broad terms, a lower mafic volcanic unit is succeeded by a sequence of intermediate to felsic flows and related tuffs, which is in turn overlain by a package of clastic and chemical metasediments consisting of conglomerate, sandstone, siltstone-argillite, chert, and derived schists. In some areas there is evidence of a younger mafic volcanic unit capping the metasediments. These 'upper' mafic volcanics are probably related to numerous late stage gabbroic intrusions which occur as small stocks and elongated dykes or sills. These rocks have been folded, faulted, and metamorphosed to green schist facies metamorphic grade, and are preserved in a northwesterly to easterly trending synclinorium herein referred to as the Manitou Lakes Synclinorium. This volcanic ' trough' is bounded on the southeast by the Irene-Eltrut Lakes batholithic complex and on the northwest by the Atikwa batholitic complex. Felsic metavolcanics and metasediments occur along the core of the synclinorium and are flanked by broad belts of mafic volcanics. Major schist zones related to folding and faulting parallel the trend of the synclinorium. These zones of weakness have been the focus of late stage (Kenoran) felsic dyking, further transcurrent faulting, and have acted as conduits for hydrothermal fluids which have produced intense hydrothermal alteration. Gold deposits in the Manitou Lakes area are closely related to these major structures. The schist zones may be the result of penetrative deformation fabrics along major isoclinal (?) fold axes and/or may have been produced by transcurrent and vertical movements along a "mobile" zone separating the major crystal blocks represented by the Atikwa and Irene-Eltrut Lakes batholithic complexes.

Feb 24, 2010 (C Ravnaas) - Previous work consisted of a trenching and blasting program carried out by CanAmerica prior to the herein described drilling program. Assays from this work ranged up to 0.437 oz/ton and indicated potentially economic grades of 4.1g (0.132 oz)/tonne over widths of up to 7.5m at the "E" zone, providing sufficient encouragement for the ensuing drill program. During February and March, 1987, CanAmerica Precious Metals Inc. conducted a shallow, first tier 15 hole - 2,513' (766 metres) drilling program to investigate promising structures and surface assays at the "E" and "F" zones at the company's Manitou Lakes gold property in Kenora Mining Division, northwestern Ontario. Drilling at the "E" zone has delineated a 5m to 8m thick quartz-pyrite stringer stockwork/breccia zone over a strike length of approximately 350 m, containing potentially economic grades over potentially mineable widths. Utilizing different variables, drill indicated and inferred tonnages and grades at the "E" zone range from 143,685 tonnes grading 5.21 g (0.167 oz) per tonne to 529,650 tonnes grading 3.20g (.103 oz) per tonne, indicating between 25,000 and 50,000 ounces of contained gold in a wide zone at shallow depth.

Jul 07, 2022 (D Scholtz) - "E" Zone - First pass mapping and sampling of the "E" zone in 1985 returned assays of up to 4.1g (0.132 oz)/tonne from a silicified quartz-pyrite stringer stockwork zone. Subsequent trenching, blasting, and bulk sampling returned weighted average assays of approximately 4 g (0.13 oz)/tonne over a width of 7.47m (24.5') from three trenches spaced over a 50 m strike length along the zone. These very encouraging results provided justification for the ensuing 766m (2,513') first tier diamond drilling program of 15 shallow holes (Figure 4) carried out during February and March, 1987. The "E" zone is a 5m to 8m wide, northeasterly striking, steeply southeasterly dipping (approximate attitude 045°/70SE) intensely silicified stringer stockwork zone developed subconcordantly in a dacitic lapilli tuff to tuff breccia unit. An early generation of silicification has obliterated the fragmental volcanic textures and the resulting altered rock is an aphanitic to fine-grained, dark to light grey or buff colored completely recrystallized zone. The silicified zone exhibits relatively sharp contacts with an outer envelope of chloritic alteration and shearing which varies from a few metres to tens of metres in thickness, and is characterized by intense foliation, the development of chlorite, recrystallization, and obliteration of the original fragmental volcanic textures. The effects of chloritization are apparent for several tens of metres from the walls of the silicified stockwork zone but the boundaries of the chloritic envelope are arbitrarily placed at the point where original volcanic textures are first discernible. The earlier generation of silicification is accompanied by an early set of dark grey or black to light grey narrow quartz stringers or veinlets varying from 0.1mm to 1 or 2cm in width, which dip steeply and strike obliquely across the trend of the main silicified zone. Their approximate attitude is 016°-020°Az/75°-85°SE, in contrast to the 045°Az/70°SE trend of the silicified envelope and enclosing volcanic rocks. The stringers contain variable amounts of fine-grained pyrite and are accompanied by weak pyritic haloes, giving the earlier silicified stringer zone an overall pyrite content of 0.5% to 3% or 4%.
