Feb 09, 2011 (Peter Hinz) - The area is underlain by the High Lake porphyritic granodiorite stock, which intrudes Archean mafic metavolcanic rocks. The stock has been interpreted to be two intrusive phases (Davies 1965, Colvine 1979). 'South and west of Electrum Lake a sequence of massive and pillowed basaltic flows, essentially devoid of interlayered pyroclastics or sediments, is cut by porphyritic granodiorite of the High Lake stock. The porphyry occurs as dike-like bodies trending approximately east, on the margins of the main body of granodiorite. The porphyry and basalt are unconformably overlain by sediments of the Crowduck Lake Group. This unconformity extends south-southeast through Electrum Lake and has been mapped about 100m north of the A-D occurrence (Davies 1965). Here, the sediments are cherty and argillaceous and the contact with the porphyry is not convincingly an unconformity. The contact between the basalt and the porphyry is irregular in the vicinity of the A-D trenches; the main contact is an open, curving Z-shape, and quartz appears to occu in gas fractures which mimic this curve. There area has been subjected to two periods of folding and subsequent modification along east-southeast-striking fault zones, and the gash fractures may be related to the late-stage dextral faulting.' (Davies and Smith, 1988)'. High Lake Property lies in the Lake of the Woods greenstone belt. This greenstone belt is located near the western end of the western Wabigoon region of the Wabigoon Subprovince. The Eastern end of property is underlain dominantly by mafic to intermediate metavolcanic rocks, metasedimentary rocks (argillite, shale) and approximately 10 to 20% felsic dykes and sills. The centre of the claim group contains intercalated zones of felsic intrusive rocks and mafic to intermediate metavolcanic rock (approximately 50/50). Systems of east-northeast and east-west trending faults cut all rock types Reference Sears, S. Technical Report on Alcock and High Lake Property for International Millennium Corp. June 2006.

Feb 09, 2011 (C Ravnaas) - The mineralization on the High Lake property occurs in alteration zones (silica-sericitesulphide) associated with structural features (shear zones and wall rock xenoliths) within an Archean-aged volcanic and quartz porphyry intrusive environment. The four prospects have only been explored to shallow depths and the remainder of the property has excellent geological potential for hosting other similar deposits Reference Sears, S. Technical Report on Alcock and High Lake Property for International Millennium Corp. June 2006.

Feb 09, 2011 (Peter Hinz) - In the main zone, 'a complex of quartz veins, most of which trend within 20 degrees of N75W, includes numerous lenses of altered quartz porphyry and volcanic material. Much of the quartz contains tourmaline. Pyrite, ankerite, pyrrhotite and chalcopyrite are commonly associated with tourmaline. Gold occurs with the sulphides, and also in fine to coarse, visible grains' (Davies 1965, p.36). Lytle (1959) concluded that 'Quartz showings are numerous and are located in both the greenstone and porphyry, which show considerable alteration. The zones of quartz follow the general structure and when located off the nose of dragfolds, or at least certain ones, contain varying gold values and some fine visible gold. The mineralization associated with the quartz consists of pyrite, pyrrhotite, chalcopyrite and gold.' (Davies and Smith, 1988)'. Several different types of mineralization occur on the High Lake Property. The most important of the known styles of mineralization consist of Au associated with quartz veining and silicified zones that are spatially related to the contact between a quartz feldspar porphyry (QFP) sill or dyke and a mafic to intermediate volcanic unit. The High Lake Property contains several known gold and gold-copper-molybdenum prospects that warrant an aggressive exploration program. The best known targets consist of Au mineralization hosted within quartz veining and silicified shear zones that have developed proximal to contacts between quartz-feldspar porphyry sills and mafic to intermediate metavolcanic rocks. Purdex Zone: In 1989, G.M. Leary, MSc, P.Eng. estimated, on behalf of Consolidated Jalna Resources Limited, approximately 250,000 tons of material grading from 0.25 to 0.30 ounces gold per ton (226,800 tonnes grading between 8.57 and 10.28 g/t Au). Reference Sears, S. Technical Report on Alcock and High Lake Property for International Millennium Corp. June 2006.
Oct 30, 2015 (Therese Pettigrew) - Four grab samples from the Purdex trench collected in 2006 ranged from 6.46 to 17.7 g/t Au and had an average grade of 9.84 g/t Au over a width of 10.0 m (Sears, 2006). DDH MLHL-23-43 returned 21.1 g/t Au over 0.33 m from 248.67 m depth and 8.27 g/t Au over 3.95 m from 251.35 m depth (McFarlane Lake Mining news release April 11, 2023).
