The Golden Cross Mine site is situated eight kilometres northwest of Waihi in the Waitekauri Valley at the base of the Coromandel Peninsula. After producing 20.5 tonnes of gold and 52 tonnes of silver between 1991 and 1998 (worth $NZD430m at 2001 prices) the operation became the first modern mine in New Zealand to successfully move into planned closure and final rehabilitation.

It first operated as an underground gold mine from 1895 to 1920 and had produced two and half tons of gold in this time.
