"People come down here and drop their jaws," said its owner, Sean Jacob, as he stood in the centre of the rock chamber. The cave is 106 metres long and up to five metres high. Part way in, the tunnel, which was formed when Mount Eden erupted 28,000 years ago, narrows and then opens into what Jacob calls "the ballroom" - a lofty area shimmering with golden minerals.
Beyond is a 10-metre crawl space that leads to another chamber. Jacob has attempted to enter it just once. "You draw blood," he said. "It is like going through a cheese-grater."
