outright by Rio Tinto Ltd (CRA) in 1984 who completed

the open-pit mining. Underground operations

commenced in 1986 and the project was sold to

Denehurst Ltd in 1987 who continued underground

mining up until 1998. The mineral rights to the project

were then acquired by TriAusMin Ltd in 1999 who

conducted studies on a tailings re-treatment process and further underground operations. Heron took 100% ownership of the project in August 2014 following the merger of the two companies. Some 980 surface and underground drill holes have been completed on the project to date and various studies undertaken.
