Primary Commodities: Asbestos
Secondary Commodities: Nickel
Township or Area: Kenogaming
Latitude: 48° 8' 47.69" Longitude: -82° 0' 7.71"
UTM Zone: 17 Easting: 425457.09 Northing: 5333077.8 UTM Datum: NAD83
Resident Geologist District: Timmins
NTS Grid: 42B01NE
Point Location Description: Mineralized outcrop on the shore of Hanrahan Lake.
Location Method: Data Compilation
Access Description: The easiest access is via the Kenogaming and Penhorwood main haul roads. From these roads the best access is via boat down Hanrahan Lake. Alternatively an old trail from the Penhorwood road comes to within a kilometre of the outcrop.
1956: Dunvegan Mines started an exploration program for asbestos and nickel in the area. Though a number of trenches were excavated southeast of Crawford Lake there are no reports of any asbestos mineralization being found. 1957: Canadian Johns Manville carried out a ground magnetic survey over the area in conjunction with geological mapping. Only restricted occurrences of asbestos were found. 1965: Canadian Johns Manville carried out an airborne magnetic survey over the area which was followed by ground magnetic and electromagnetic surveying. Based on this work eleven shallow holes were drilled to the east of the original mineralized outcrop but no mineralization was intersected. 1972: While mapping the area for the Ontario Division of Mines, Vic Milne observed a number of other asbestos occurrences between Hanrahan and Crawford Lakes. 1973: Hanna Mining carried out a reconnaissance nickel exploration program in the area during which the Johns Manville core was assayed for nickel. The best assay was 900ppm Ni in sulphides. 1983: R.J. Sheppard as part of the HWS syndicate recompiled the regional geology based on previous work and a detailed airborne magnetic and EM survey. 2005: Golden Chalice Resources Inc.- AEM, AMag.

Dec 07, 2005 (S Fumerton) - The host serpentinized peridotite is coarse grained, granular and olive green. In places the rock is considerably altered to talc and or carbonate especially where the ultramafic is cut by a northwest trending fault.
Dec 07, 2005 (A Wilson) - The occurrence consists of three separate asbestos showings on the east shore of Hanrahan Lake.

Dec 07, 2005 (S Fumerton) - Fibre showing in the serpentinite are meagre in the extreme. They are confined to two outcrops. Here the altered ultrabasic carries thread veins and occasional 1/32 inch veins.
