Point Location Description: Small scale gold mill; misc. buildings; stripped and trenched areas.

Location Method: Conversion from MDI

Access Description: The prospect is located in Priske Township, about 8 km east of Schreiber, approximately 2.8 km north of Highway 17, and 1.5 km northeast from the northeast shore of Hays Lake (claims TB221713, 221714, claim map G-631, Priske Township). Hays Lake is accessible via the Hays Lake gravel road from Highway 17. A boat is required to cross Hays Lake (approximately 5 km across), at which point a truck road on the northeastern shore can be followed to the gold mill on claim TB 221713. A longer route, suitable for tractor haulage, follows the Ontario Hydro roads from Schreiber, past Cook Lake and east and south to the gold mill road.

Exploration History

1934-35: The area was staked by J.E. Derraugh and preliminary exploration and dev't work was carried out on the main (discovery) quartz vein. 1937: Jedder Gold Mines Ltd.'s surface sampling reportedly indicated a 152.4 m section averaging 0.23 oz/ton Au over an average width of 0.46 m--an unreported amount of diamond drilling did not substantiate this. Work ceased. 1963: Claim block was staked by R.V. Hannam. 1964: Unspecified work carried out. 1969: W. Acker staked a 4-claim group. 1970-74: Manual and mechanical stripping and bulk sampling was carried out on claims TB221713 and 221714. 1972: W. Acker constructed a small-scale gold mill on site and bulk sampled (500 lbs/hr). 1975: 21 year leases were granted for TB221713 and 221714. 1984: W. Acker located another showing (G Vein or J, K, L Veins?) 220 m north of the original showings. Morgain Minerals Inc. optioned 6 claims (Hays Lake group). A mag survey was conducted in Nov. 1985: Phantom Expl'n Services channel sampled for Morgain Inc. Property reverted to W. Acker. 1986: A pilot gold mill was tested. 1987: Beardmore Resources Ltd. optioned the property and carried out minimal soil and lithogeochemical sampling. A video was filmed of the operation of the Hays Lake Mill for small scale mining purposes. 1988: Beardmore Resources drilled 2 holes totalling 394.5 feet. 1989: Corona Corp. carried out mapping and sampling. 1990: Property was optioned by Bond Gold Canada Ltd. which carried out geological mapping, HL-EM and mag surveys, humus and lithogeochemical sampling, prospecting and stripping. 1995: The property is currently held by the estate of the late Walter Acker. The property was optioned to RJK Explorations Ltd. Stripping and sampling was conducted.

Geology Comments

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

Dec 07, 2005 (B Nelson) - The general geology consists of metavolcanic and metasedimentary rocks which have been intruded by granitic rocks at the Terrace Bay Batholith. The metavolcanic rocks include pillowed and massive mafic to intermediate flows, with minor intercalated felsic flows. The metasedimentary rocks are predominately composed of wacke, siltstones and slate of turbiditic origin. Iron formation, consisting of chert, massive pyrite sections and graphitic pyritic slate is also present. The rocks in the Harkness Hays Gold Range are have been intensely faulted and fractured. This is evident on top of the Gold Range Ridge. Air photo interpretation indicates a conjugate set of faults striking northeast and northwest. The northwest striking fault set has apparently offset the Gold Range Ridge, in a dextral sense, up to 0.5 km. In excess of 25 small scale lineaments were observed. Field evidence indicates that many of these lineaments represent faults. The vein systems occupying these faults are often brecciated. Marmont and Colvine (1981) visited the property and noted that it consists of: ...a quartz vein hosted by pyritic, basaltic flows which are intruded by a pink, fine grained to aphanitic quartz feldspar dike. The vein strikes 60 degrees and dips 85 degreesN. The average width of the vein is about 50 cm and it has been exposed over a length of approximately 150 m. The vein occupies a shear zone and consists of white, glassy quartz which in places is highly brecciated and carries pyrite, chalcopyrite, galena, gold and silver.

Lithology

Lithology Comments

Dec 07, 2005 (B Nelson) - The veins are hosted by amphibole rich or amphibolitized mafic metavolcanic rocks, consisting of excellent exposures of pillowed flows and hyaloclastite. Previous workers indicated the presence of mafic to ultramafic intrusive rocks. The coarse grained amphibolitized mafic metavolcanic rocks could be interpreted as such. The flow rocks can display a porphritic texture with phenocrysts of hornblende. Intruding the metavolcanic rocks are granitic dikes of at least two ages or generations. The older granite dikes appears to be a white to pink aplite, commonly subparallel and in contact with the veins. In addition a grey, quartz porphyry unit appears on the north or hanging wall of the Mill vein. The younger granite dikes are represented by reddish biotite granite. These dikes crosscut the quartz veins and appear to have no preferred orientation. In several exposures the quartz vein observed appears transitional in texture and composition into the aplite dikes. A genetic relationship between the white to pink aplite dike and mineralized quartz veins exists. The gabbro in the north eastern area of the group are altered in appearance and may be metavolcanics. The gabbros in the central area and south of the main showing are fresh and unaltered in appearance, exhibit increase in grain size towards the centre of the mass, appear to have sharper contacts with the enclosing volcanics and have shapes non conformable to the general rock trend. These gabbros may therefore be intrusive.

Mineralization

Mineralization Comments

Dec 07, 2005 (B Nelson) - Ekstrom (1983) noted that: Gold has been recovered from the deep trenches at the main showing and the trench on the base line at 100E. The quantities of gold produced have not been reported. During the.1983 survey, pyrite, chalcopyrite and galena were seen in the trenches at the main zone in fragments of quartz vein and altered volcanic material. Pyrite was observed at the pit associated with a quartz vein (up to 10 inches wide) in sheared and bleached altered volcanics. Disseminated and fracture filling pyrite were found over the whole property. Minor quartz lenses, veins and stockworks were seen at many unrelated locations but often at scarp faces. Specks of chalcopyrite and copper stain are common. Thirteen channel samples were taken in November 1984 by Phantom Exploration Services Ltd. for Morgain Minerals Incorporated, form an approximate 87 m section of the Mill vein. The southwest section of the Mill vein was sampled. Values of up to 1.152 ounces gold per ton and 2.134 ounces silver per ton over 1.5 feet (0.5 m). All results are within Resident Geologist's Files. Samples collected by Bond Gold Canada Ltd. in 1990 returned the following assays (best results shown): J Vein: 9.26 g/t Au over 0.30 m. K Vein: 7.89 g/t Au over 0.30 m. L Vein: 5.14 g/t Au over 1.0 m.

Alteration Comments

Dec 07, 2005 (B Nelson) - The sheared metavolcanic rocks commonly in contact with the quartz vein display sericitization, carbonatization, silicification and pyritization similar to the alteration present at both the Harkness Hays and Gold Range properties.
