NATIVE COPPER

Cu
Elemental Copper


Cap D'or (Hanway Shaft), Cumberland County
UTM (NAD27)
Zone 20
 Northing 5019010
 Easting 363785
Details:
 Drive south from the community of East Advocate along the road leading to the Cap d'Or lighthouse (now also a restaurant) for 2.1 km to an old woods road (now a trail) leading east from the road. The entrance to the trail is found immediately past (south) of a sharp left-hand turn in the road shortly after cresting the hill. The trail is only passable by 4-wheel drive. Proceed east along the trail for 1.43 km to a junction with another trail leading to the south. Take this south trail and walk for 217 m to the old mine workings. Along the way you will start to notice evidence of the past mining within about 100 m of taking this south trail. This location essentially brings you to the intersection of the old mines road and a narrow guage rail line that serviced the workings. The rail line continued toward the west. The main workings (Hanway Shaft) are found southeast of this rail/road intersection. Notice a trench along the east side of the road and leading to the south. This trench essentially follows the mineralized fault structure and if you follow it south you will come upon the Hanway Shaft. BE CAREFUL the shaft, although fenced (1996), is heavily wooded, still completely open and is free of water to a depth of many tens of metres. A short distance siuth along the trenched fault structure from the shaft one encounters the cliff face. Although tempting, it is not possible to reach the beach by clambering down the cliff face along the fault.

 GEOLOGICAL DESCRIPTION
Structure: Cliff exposures indicate that the basalts dip gently to the south. The mineralization appears to be related to northerly sriking, vertically dipping breccia zone over 450m long, up to 30m deep and 245m wide. Mineralization: The breccia zone is not only cemented by carbonate, but is also occupied on the east side by a large carbonate vein which is mineralized with irregular flakes of native copper. The mineralization is reported to be 1.2m wide at the 30m level, 8.5m wide at the 60m level and 3m at the 90m level. Stopes between the 30m and 60m levels are reported to have yielded 2.5% copper (Douglas, 1943).
PREVIOUS WORK
The Colonial Copper Company worked three principal areas between 1901-1907 (Messervey, 1929). The three areas are: the Hanway, Number 1, and Bennet Brook workings (Messervey, 1929). The principal workings were developed on the Hanway lode. This lode followed a near vertical quartz vein which averaged 25.4 cm, and was located on the east side of an irregular vein of volcanic breccia (Bancroft, 1953). The majority of the ore was found in the Spencer flow which is lowest flow in the volcanic pile. At least two references note that gold was found in the Cape d'Or area. The Industrial Advocate (1906) states: "It is reported on what appears to be good authority that the ore that has recently been mined at the Colonial Copper Mines, has considerable quantities of gold mixed with the copper." The mineralized zones and workings are summarized in the report by Douglas (1942) and in the assessment reports listed in the references.
