Point Location Description: Point located from 1972 Selco Mining Corp assessment file.
Location Method: Conversion from MDI
Access Description: Approximately 315 km NE of Pickle Lake, 65 NNW of Webequie and 1.5 km north of Sourdough Rapids on the Ashweig River. Access is by float plane from Pickle Lake, landing on Sourdough Lake on the Ashweig River and then canoeing 3.2 km downstream; or alternatively by helicopter from the airport at Kasabonika to a helicopter landing zone located apprx. 100 m NW of the showing at 446670E 5967725N.
Government airborne geophysical surveys were done on a reconnaissance scale over the area from 1965-1968. 1970 – Mr. Solomon Suganaqueb of Webequie discovered Ni and Cu mineralization beside a small tributary stream that enters the Asheweig River from the west roughly 4 km downstream from Sourdough Rapids and staked the area. 1972 – Selco Mining Corporation optioned the property and carried out a trenching (4) and blasting program. Selco dropped the option. No work was done for years. Mr. Suganaqueb maintained control by successively restaking the property. 1978 – magnetometer, radiometric, and geologic surveys were commissioned by the Indian Minerals Division of the Department of Indian and Northern Affairs. 1979 – government mapping was done on a reconnaissance scale over the area. 2005 – geological mapping and geochemical sampling was conducted by Kasabonika First Nation and D’Silva Parker Associates.

Jul 17, 2014 (N Bennett) - Gabbro is interpreted to be a local remnant feature within the felsic intrusives and the higher grade mineralization is due to contact metasomatic processes rather than orgininally in situ (Anderson, 1972 – AFRI 43E13SW0002).
Jul 17, 2014 (Therese Pettigrew) - A 200’ inclusion of mineralized gabbro constitutes the Ni-Cu showing that caused the claims to be staked. All included rocks are highly altered. It is possibly proximal to a contact with a basic rock to the east. The profusion of inclusions suggests that it is near the top of the intrusive and these are roof pendants (Seeber, 1978 – AFRI 43E13SW0001). The area is located within the Kasabonika-Shibogama Greenstone Belt and along the western extension of the North Kenyon Fault (Anderson and Parker, 2005 – AFRI 20001745)

Oct 29, 2010 (N Bennett) - Cu assay values from trenches range from 0.02% to 0.77%. Ni assay values from trenches range from 0.03% to 0.73%. These samples were taken over 10 foot intervals.
Jul 17, 2014 (Therese Pettigrew) - The sulphide mineralization appears to be scattered at random through the gabbro and/or quartz diorite; no precise structural control was noted for localization of he sulphide concentrations. It is suspected that the sulphides are pre-granite in age (Seeber, 1978 – AFRI 43E13SW0001).
