Point Location Description: West of Big Whopper

Location Method: Data Compilation

Access Description: The property is accessed by travelling north from Kenora along Highway 658 to the English River Road turnoff, approximately 2 km south of the town of Redditt on the CNR mainline railway, then north on the English River Road to a boat landing and campground at Separation Rapids. From the Separation Rapids campground, the property can be reached by boat, 8 km west along the English River. Alternatively, the property can be accessed by logging roads off the English River Road, namely the Sand Lake Road and the Snook Lake Road, which terminates immediately west of the property. A 2 km bush road cleared in September 1997 for drill access from the termination of the Snook Lake Road can be travelled in the winter months by four-wheel drive and in the spring and summer months by ATV.



Exploration History

1996: Avalon Ventures Ltd. acquired the property. 1997: Avalon conducted linecutting, and a ground magnetometer survey.
