Point Location Description: Drill collar ddh F-82-3 located in NW corner of claim P626290 100'S and 80'E of #4 post.

Location Method: Data Compilation

Access Description: Access is via the turn off from Highway 101 onto the Dore or Foleyet Lumber Road, 100 km to the west of Timmins and 10 km east of Foleyet. From the highway follow the road south approximately 7 km. The showing is about 100 m west of road.

Exploration History

1966 Canadian Johns Manville Co. Ltd. conducted a ground magnetic survey which covered the area of the showing. 1980-83 Hudbay Mining Co. Ltd. conducted an airborne magnetic survey over an area of the southeastern corner of Foleyet Township into the northwestern corner of Keith Township. The geophysics was followed up by an 8 hole diamond drill program on their claim groups in the northwestern corner of Keith Township. One hole returned anomalous values of zinc and gold (showing in hole F-82-3) in a unit described as a graphitic pelite and a rhyodacite tuff respectively. 1991: Falconbridge Ltd. – EM, Mag.

Geology Comments

Dec 07, 2005 (K Houle) - Pelite/psammite unit is bedded and shows some graded bedding with fining downhole. Possible cross bedding observed indicating curvilinear bedding surface. Bedding occurs at approximately 50 degrees to core axis.

Lithology

Lithology Comments

Dec 07, 2005 (K Houle) - The zinc anomaly occurs in a drill log at a vertical depth of 28m and is reported as a graphitic pelite/psammite. This unit is described as being grey, conductive and consists of silicified graphite beds alternating with pelite/psammite beds. Occasional 2-3mm quartz clasts are reported in psammite beds. Upper portions of some beds are reported as being sericitized while the lower portions are silicified. Unit becomes heterogeneous beyond the psammite beds. Graphitic beds of several cm's to 60cm in width become dirty and non-conductive and appear fragmentary containing 3-5% sulphides. Unit is described as chloritized and contains 5-10% carbonate. Lower contact is gradational. Gold anomaly is treated here as only a minor showing and occurs in a rhyodacite lapilli tuff unit at a vertical depth of 67.5m. Unit is described as being light grey green and fine grained with occasional 1cm lapilli. Unit is very siliceous and contains 20-25% matrix and stringer carbonate. Sulphides, pyrite and pyrrhotite, are located in the more felsic portions of unit and occur up to 10% disseminates and wisps.

Mineralization

Mineralization Comments

Dec 07, 2005 (K Houle) - Zinc anomaly is associated with a 60cm graphitic bed containing 3-5% pyrrhotite and pyrite in stringers and disseminated along bedding planes. Approximately 1% chalcopyrite in lower 20cm of bed. 3-5% finely disseminated pyrrhotite and pyrite are also associated with silicified zones and 3-5% pyrrhotite, pyrite and trace chalcopyrite occurring as stringers and disseminates have been noted as occurring in some dirty graphitic beds.

Apr 02, 2015 (A Wilson) - The best zinc assay for the occurrence is 0.47% Zn over 60 cm. The best gold assay is 0.016 oz/t Au (0.55 g/t Au) over 1.0 m. The gold anomaly is presumed to be minor and is related to a rhyodacite tuff at 67.5 m in drill core (T-2430).
