It cannot be entered, and there is little to mark it out from the surrounding trees. Yet its presence is a quiet reminder that the landscape now associated almost entirely with Killarney's scenic lakeland once had an industrial dimension, one measured in copper ore rather than tourism.

The shaft most likely dates to the second half of the eighteenth century or the early nineteenth century, a period when copper mining was actively pursued across parts of Kerry and Cork. Vertical shafts of this kind were sunk to reach ore-bearing seams below ground, with miners working downward and outward from a single access point. This particular shaft appears to have been a modest operation, or at least a discreet one, in contrast to the more substantial mining complex recorded approximately two hundred metres to the west, which encompassed a much broader range of workings. Whether the shaft on the peninsula was connected to that wider effort or represented a separate, smaller venture is not recorded.
