The possible extension of the Hammerdown gold deposit has always been limited by the Captain Nemo Fault which removed the lower extension of the vein system in an unknown direction. The veins are terminated between 150 metres and 250 metres depth by this very sharp fault. Fragments of the ore grade veins were actually encountered in the fault during mining operations by Richmont Mines. However, they only drilled two deep holes in search for continuation of the veins.
The direction and distance of the fault offset has never been resolved, however geological and magnetic mapping of the property indicates it has not been moved more than several 100's of metres. In late 2010, Maritime completed a deep searching geophysical survey to the south of the Captain Nemo fault and located a target at depth. There has been preliminary testing of this target and it remains available for further work.
