Point Location Description: Shafts, diamond drill holes, trenches, stripped area.

Location Method: Conversion from MDI

Access Description: The property is located about 400 m west of Big Duck Creek between Hollinger Lake and the Schreiber Pyramid showings, approximately 5 km northeast of Schreiber in Priske Township. (claim TB 28130, claim map G 631, Priske Twp). Access may be gained using a 4x4 road that extends north and east of Schreiber to the old workings. Branches of this road lead to the southeast 2.5 km from north of Cook Lake. Secondary access is achieved by foot from Highway 17 following the existing trail that passes just west of the Gold Range property to the southeast end of Von Lake.

Exploration History

1921: Rich veins were first reported southeast of Cook Lake. 1934: Claims were staked by F.A. McKenna, D.T. McCann, and H. O'Brien. A discovery was made by McKenna and McCann in the northeast corner of TB12881. 1935: Trenching and stripping conducted. Property was optioned to Dumond Mining and Exploration Company Ltd. who then initiated a third party option with T.A. Johnson. T.A. Johnson drilled several holes under the main showing. 1937: Cook Lake Gold Mines acquired the property. Bulk sampling was performed; Harcourt of the Ontario Department of Mines identified 4 parallel veins; 2 compartment shaft initiated at main showing. 1938: Main vein length established at 183 m; Inspector of Mines shut down the shaft because of contraventions of the Mining Act. Cook Lake Gold Mines discontinued operations due to lack of funds. 1940: 17 claims cancelled. 1941-1972: Claim TB28130 was patented in 1941, then changed hands several times. 1946: J.D. Grant purchased the Cook Lake Mine property and formed the Antelope Syndicate. During winter mining operations, C. Martin shot J.D. Grant and A. Duchesneau at the Antelope Mine (McKenna-McCann). It came open in 1961, and was staked. 1972-77: Extensive mechanical work undertaken by W. Acker; shaft was dewatered and sampled. 1983: Morgain Minerals acquired the property and carried out line cutting and geological mapping. 1984: Channel sampling conducted for Morgain Minerals. 1985: RTC Precious Metals Inc. carried out stripping, trenching, road dev't, and minor property dev't. Minor tonnage was reportedly removed. 1986: Jim Kraehling bought the property from W. Acker. 50 tons of ore was bulk sampled. 1987: R. Otto bought the property. 1988: R. Otto drilled 1 DDH totalling 31.7 m. 1989: Acker and Otto stripped, trenched and sampled SE of the McKenna-McCann property; extensive carbonate alteration discovered and named the Cabin Carbonate Zone. 1990: The W3 vein system was discovered. 1991: W3 veins were stripped and trenched; McKenna-McCann shaft was dewatered. 1992: Acker and Otto died of CO poisoning while dewatering the shaft. 1993: McKenna-McCann property held by the estate of R. Otto. The W3, W3 Extension and Cabin Carbonate Zone held by the estate of W. Acker. 1995: Property optioned to RJK Explorations Ltd. 1998: The property was staked by A. Wing. 1999: A. Wing contracted C. Larouche to carry out a small mapping and sampling program. 2002: S. Kravchik carried out prospecting and sampling. 2007 & 2009: O. Kravchik contracted G. Daniels to do prospecting and sampling. 2010: O. Kravchik contracted Fladgate Exploration to do a soil sampling program. 2017: First Minerals Exploration Ltd. carried out channel sampling.

Geology Comments

Dec 07, 2005 (B Schnieders) - (See Nelson).

Dec 07, 2005 (B Nelson) - The general geology consists of predominantly mafic, spherulitic pillowed metavolcanic flow rocks, and minor iron formation which have been intruded by metagabbro and metadiorite dykes, lamprophyre dykes and small quartz feldspar porphyry stocks or dykes. Pillow cusps indicate tops to the northeast. Air photo interpretation and field evidence suggest several major northwest trending lineaments, including a Big Duck Creek Hays Lake lineament, Hollinger Lake lineament and a Craft Lake Lamont Lake lineament. A secondary or minor fault set trending southwest northeast, and occasionally north south is present within this area. This conjugate fault set appears common in areas of gold mineralization. The northwest trending shear zones are sub parallel to the long axis of the stretched pillows. An approximate 5 by 3 km rectangular parcel of land in this area, bounded by the Croft Lake lineaments discussed is highly recommended for prospecting and exploration. The quartz vein system at the McKenna McCann property displays many similarities in style and appearance to quartz veins at the Johnston McKenna, Schreiber Pyramid, W3 and W3 Extension properties. Gold bearing quartz veins occupy shear zones or shear dilatant zones within metavolcanic rocks. The host metavolcanic rocks are predominantly mafic pillow flows, however minor massive flows are present. The metavolcanic rocks commonly display carbonatization in the vicinity of gold mineralization. A parallel set of 4 en echelon quartz veins (Nos. 8 through 11) strike to the northwest, varying from 180 degrees to 330 degrees and dip 55 degrees to 70 degrees SW. The zone containing the veins is approximately 25 m wide. The zones vary from composite veins to individual veins which are lenticular and average 33 cm in width and have been traced along strike for up to 225 m. The veins commonly display a crack seal or ribbon texture, and occasionally a brecciated texture.

Mineralization

Mineralization Comments

Dec 07, 2005 (B Nelson) - Visible gold was observed by Ekstrom (1983) in up to 6 locations. However, the gold mineralization is both erratic and sporadic. The veins have been designated from southwest to northeast as Nos. 8, 9, 10, and 11. They are arranged en echelon and tend to pinch and swell along the strike, alternately appearing as stringers in a narrow shear zone and then swelling to 2 and 3 feet for short distances. The quartz is milky and very brittle with a scattered mineralization of pyrite, chalcopyrite, galena and a considerable amount of fine native gold. The gold is most prominent along minute fractures in the quartz, appearing as a film on the fracture faces. (Gold at $34.98 per ounce, 1937 price). No. 10 vein average $18.88 (0.54 ounce per ton Au) over an average width of 1.13 feet for a length of 130 feet. No. 9 vein includes a 100 foot section which averaged $8.96 (0.26 ounce per ton Au) over 1.17 ft. and a second section 70 feet in length which showed negligible values. No. 8 vein averaged $5.34 (0.15 ounce per ton Au) over 1.47 feet over a length of 110 feet. (Resident Geologist's Files, Schreiber Hemlo District, Thunder Bay) In 1973, a one ton bulk sample of quartz was collected from the shaft dump and milled by W. Acker at the Hays Lake Mine. The sample was reported to indicate 0.50 ounce per ton Au.

Alteration Comments

Dec 07, 2005 (B Nelson) - Resident Geologist personnel obtained an assay result of 0.90 oz/ton Au from a sample containing visible gold along sericite seams (No. 10 Vein).
