Point Location Description: Point located is the drill set-up for a diamond drill hole BR 75
Location Method: Field Visit with GPS
Access Description: The prospect is located some 70km west-southwest of Timmins and easy access is possible via Highway 101 to the Reeves Mine turn-off. From the highway the road goes 2km south to the old mill at the Reeves Mine. The prospect is located southeast of the mill.
1951: Asbestos was discovered in the area to the north by J.C. Bromley while prospecting. 1951:The property was acquired by Johns Manville who started an exploration program in the following year. This exploration program continued for over twenty years consisted of geological mapping, magnetic, electromagnetic surveys and diamond drilling. Though this program was centred on the Reeves Mine outlying areas were also covered. This occurrence is blind and was found by drilling geological and geophysical targets.

Dec 07, 2005 (S Fumerton) - The prospect is located in compositionally layered ultramafic rocks which may be part of an intrusive plug or a thickened sequence of komatiitic flows in the nose of a fold. Else where these flows or lenses are conformable with Mg tholeiitic and calc-alkaline flows. Originally these ultramafics were divided into early and late ultramafic intrusives by Milne 1972 but the occurrence of compositionally controlled spinifex texture was noted in settings now regarded as characteristic of layered komatiitic flows.
