Point Location Description: Clearing on east shore of Lee Lake.
Location Method: Field Visit with GPS
Access Description: Road access may be accomplished by taking Highway 677 off of Highway 129 south of Chapleau as far as Kormak station. A road leads north from Kormak about 20 km where it will take you where the Sylvanite Creek crosses the road in northwest Greenlaw Twp. A canoe trek up the Sylvanite Creek into lower Lee Lake makes for easy access to the occurrence.

Dec 07, 2005 (K Houle) - Hole SW-49 intersects a series of alternating sections of rhyolitic breccia, graphitic argillite and sericite schist. The cherty rhyolite breccia is described as being highly foliated, with poorly sorted irregular rhyolitic fragments in a dark weakly graphitic matrix. This breccia is seen to be commonly interbedded with a graphitic argillite. Hole SW-49 was drilled to the south at an initial inclination of 45 degrees to a final depth of 753' (330 m).

Dec 07, 2005 (K Houle) - Pyrite appears to be the predominant sulphide mineral present throughout the hole and appears as disseminates as well as massive to semi massive sections in core. Near massive sections range in width up to 1' (30.5 cm) with disseminates and stringers of pyrite ranging from 3-20%.
Dec 07, 2005 (A Wilson) - A gold value of 0.95 g/t Au over 1.4 feet was obtained from core drilled by Granges Exploration. The highest assay obtained by Collingwood Energy was from a grab sample that returned a value of 0.157 g/t au. Diamond drilling completed by Collingwood Energy in 1984 returned a value of 0.137 g/t Au over 10 feet from a sludge sample.
Aug 12, 2013 (P Bousquet) - Drillhole SW-49 also returned an assay of 0.64% Zn over 10ft (T-1774). This intersection was in a graphitic argillite.

Notes: An attempt was made to locate the collar of hole SW-49 but no sign of previous drilling was found except for a small clearing on the east shore of the lake that coincided to the approximate location.
