Dolphin Orebody; King Island Scheelite Mine
The King Island Scheelite mining lease area extends to Yarra Creek north of Bold Head, west to almost Lymwood and south to Colliers Beach. The lease area also extends out to sea.
Operated (2024) by Group 6 Metals Ltd (formerly King Island Scheelite Ltd until November 2021).
A group of skarn-type scheelite deposits.
Originally operated as an underground mechanised drift mine. Open cut began in the 1960s and once owned by Peko-Wallsend, Ltd. Underground mining resumed from 1973 to 1990. The mine was then rehabilitated due to low tungsten prices.
In 2015 the mine was dewatered and mining recommenced in 2023 and first tungsten concentrates produced in May 2023.
