Point Location Description: Point located is at the western end of a 10 to 15m long trench trending west northwest.
Location Method: Field Visit with GPS
Access Description: The prospect is 69km west southwest of Timmins and access is via Highway 101 to the Kukatush road. Eight kilometres down the Kukatush road is a turn off onto an old logging road leading to the prospect, however, the last kilometre has been washed out.
1946 Gold mineralization was reportedly discovered by J.C. Bromley and optioned to Kalbrook Mining Company Limited in the same year. Kalbrook carried out an exploration program which consisted mapping, trenching, and limited drilling. The only record of this work is a geological sketch map. 1967 Radio Hill Mines resumed exploration with an airborne EM survey followed with a mapping, trenching, and diamond drill program over the next two years. During this program samples from the #1 trench typically were low but assayed as high as 13 g/t (0.4 oz/ton) gold and 85 g/t (2.5 oz/ton) silver. 1986 BHP-Utah optioned the property and carried out an integrated exploration program over the next two years which consisted of geological mapping, lithogeochemical and humus sampling, together with IP, magnetic, Max-Min, Pulse EM, and VLF geophysical surveys. 1994: Noranda Exploration Company, Limited – Assays, GC, GL, Samp. 2005: Golden Chalice Resources Inc. – AEM, AMag. 2008: Golden Chalice Resources Inc. – AEM, AMag.

Metamorphism Type: Regional
Metamorphism Grade: Greenschist
Dec 07, 2005 (S Fumerton) - The mineralization is located in a fault zone trending roughly 110 within a zone of sheared metavolcanics. Minor westerly plunging drag folds occur adjacent to the vein. The regional MacKeith or Keith - Penhorwood shear zone, an east west trending structure occurs in the immediate area and the shearing in the outcrop may be part of this shear zone.
Dec 07, 2005 (A Wilson) - A number of mineralized quartz veins and stockworks were outlined in pervasively carbonatized and sheared mafic volcanic rocks cut by tonalite dikes.

Dec 07, 2005 (S Fumerton) - The mineralization in the southern or No 1 vein is hosted in an attenuated quartz vein which occurs in a sheared and altered Fe Tholeiitic basalt. North of the showing is a saussuritized, medium grained tonalite sheet trending subparallel to the mineralization. In adjacent outcrops this basalt locally has a fine compositional banding which is laterally extensive and may be a tuff, but this texture is commonly obliterated by shearing and alteration. In addition there are possible relict pillows. The alteration is commonly a pervasive though moderate iron carbonate alteration though further afield this alteration is characterised by patchy bleaching of the metavolcanics and is not associated with shearing. North of the No 1 vein is a leucocratic, pervasively saussuritized, medium grained tonalite. Locally this tonalite contains a quartz carbonate stockwork with has been called the No 2 zone and is 180m north of the No 1 zone. To the northwest this tonalite is finer, strongly foliated and altered with hematite.

Dec 07, 2005 (S Fumerton) - Quartz veins, lenses, and stringers pinch and swell along the zone achieving a maximum width of 1.2m and extends 120m. Pyrite occurs throughout the veining constituting less than 5% though is richer at the western end and associated with mafic inclusions in the veins and along the southern contact of the veins. Chalcopyrite occurs in lower concentrations throughout the veins though tends to be concentrated in a zone 5 to 15cm from the southern contact. Sphalerite and locally arsenopyrite are associated with the chalcopyrite. From the work of Radio Hill Mines sixteen samples were collected from the trench and assayed for gold and silver. The highest gold assay was 0.4 oz/ton and the rest were below 0.07 oz/ton. Two samples returned 2.5 and 2.08 oz/ton silver while the rest were below 0.28 oz/ton.
Feb 08, 2016 (A Wilson) - Grab samples from the vein taken by the OGS in 1985 returned the following values: 2.4 g/t Au, 3.0 g/t Ag; 17.00 g/t Au, 68.00 g/t Ag, 14.10 g/t Au, 66.22 g/t Ag, 26.1 g/t Au, 141.2 g/t Ag. Chip samples taken from a pit in 1992 returned values of 0.12 g/t Au and 3.0 g/t Ag.

Geologist: J Ireland
Notes: The writer carried out a program of diamond drill core recovery at the camp of Kukatush Mining Corp. in Penhorwood Twp. The major focus of the core recovery program was a stock of core from the Bromley - Bragagnola - Dunlop property at Primer Lake. Drilling was carried out in 1967 to test zones of gold silver base metal mineralization as well as geophysical targets. The property was under option to Radio Hill Mines and all core was brought out to the Kukatush camp. [ PRECIS ]

Geologist: S Fumerton
Notes: Recent logging activity has greatly disturbed the ground and a 10m trench was all that was found in the stated position of the No 1 zone. This trench is in low ground and surrounded by skidder trails which may have obliterated the rest of the trench. Similarly in the vicinity of the No 2 or X Zone. Here, the ground is high with small scattered outcrops. The only evidence found was some possible small pits near several large boulders containing a quartz vein stockwork. Otherwise the logging activity has destroyed the fabric which may have marked the trenches.
