Warning: Unstable cliffs, underwater obstacles and poor water quality represent significant safety risks.
The historical abandoned mine site Black Diamond is located within the Allanson townsite boundary in the Shire of Collie, approximately 5km west of Collie.
Black Diamond was mined between the late 1940s and early 1950s by Amalgamated Collieries Pty Ltd. The now abandoned mine void has filled with water creating a pit lake of around 700 metres in length.
The community have raised a number of serious safety concerns regarding Black Diamond, which has become a popular unmanaged recreation area. A number of environmental issues also exist, including rubbish dumping and degraded water quality.
The Department of Mines, Industry Regulation and Safety (DMIRS) is planning to reduce the safety risks associated with the southern side of the Black Diamond mine pit wall as part of the Abandoned Mines Program.
The Abandoned Mines Team have created a publication describing the Black Diamond rehabilitation project called “Improving Community Safety at the Black Diamond Pit Lake”.
The focus of the project is to address the safety risks associated with the steep slope on the southern side of the pit. Other works to make the site safe and stable may be undertaken and will be based on the outcomes of the site assessment, current works underway and stakeholder consultation.
DMIRS will release further status updates on Black Diamond through the Environment eNewsletter.
