Point Location Description: Precise
Location Method: Conversion from MDI
Access Description: The Petrie occurrence is located 54 km south-southwest of Dryden. Access to the property is via the Cedar Narrow Road off Hwy 502. At a point 77 km from Hwy 502, a road to the right, in the vicinity of Price Lake, brings one within 100 m of the occurrence. The occurrence consists of a shaft. (OFR 5731, p. 103)
1899: D.C. Petrie sunk a shaft. He took 13 samples from the shaft. Resultant assay values ranged between 0.096 and 0.33 ounce of gold per ton (Thomson 1934). 1987: Black Cliff Mines conducted ground magnetic and geological surveys over a claim group including the occurrence.. The best of 24 chip samples came from the quartz vein, northeast of the shaft, which returned 1,141 ppb gold over l m (Assessment Files, Resident Geologist N s Office, Kenora). The rocks in the vicinity of the shaft are north striking felsic tuffs interbedded with amphibolitic mafic metavolcanic rocks. A felsic dike intrudes the volcanic rocks. The metamorphic derivates of the altered volcanic rocks are hornblende-plagioclase schists. The shaft is sunk in a 25 m wide intensely protomylonitic shear zone which strikes about 175° and dips 80° to the west. A 50 to 100 cm wide quartz vein parallel to the shear zone, can be traced 80 m along the strike. At the shaft, the vein is 5.8 m wide and is enclosed in chlorite-sericite schist. Internal fabric in the shear zone ranges from N160° to N180°. Minor Z-shaped drag folds occur in the vicinity of the shaft. A shallow lineation, plunging at 30° towards 160°, occurs in the hornblende schists. This lineation, the right-steeping contact between felsic and mafic rocks, and the rotation of xenoliths in the felsic dike, suggest a dextral oblique-slip component of movement in the shear zone. The quartz vein is pale grey, opaque, and stained brown due to hematite. No mineralization was noted. One chip sample was taken by the author, on the east side of the shaft, across a 6 m width in the schist. It returned <2 ppb gold on analysis. (OFR 5731, p. 103, 104)
