Location Method: Data Compilation
1946: The property was held by Grompo Red Lake Mines Ltd. The area was prospected and one diamond drill hole was completed. A magnetometer survey was also completed. 1959: The property was included in a group held by Paul C. Reidy. One drill hole completed to the north of the property. 1981: Goldfields Resources Canada Ltd. held the property in a large claim block. Airborne magnetometer, ground magnetometer and ground EM surveys were completed over the property.

Dec 07, 2005 (K R Kettles) - GEOLOGICAL DESCRIPTION: The area in the vicinity of the occurrence is underlain by mafic pillowed and variolitic flows. The flows generally strike northeast-southwest, and dip subvertically. Foliation is parallel to subparallel to the bedding. Stratigraphic tops are to the northwest. To the southeast of the occurrence, thin units of greywackes, arkoses and iron formation are present in the stratigraphic sequence. DEPOSIT DESCRIPTION: Drill hole number 1 intersected two quartz carbonate veins, 0.75 m and 0.67 m in thickness. Both of these veins assayed 0.02 oz/ton (0.686 g/tonne) Au. GEOPHYSICL DATA: A weak EM anomaly with poor magnetic correlation has been delineated to the northwest of the occurrrence.
