Our plans

Tahmoor Coking Coal is seeking approval for the Tahmoor South Project. The project involves the extension of underground coal mining at Tahmoor Mine, to the south of Tahmoor Coal’s existing Surface Facilities Area.

The proposed development would continue to be accessed via the surface facilities at Tahmoor Mine and would utilise the existing surface infrastructure at the Tahmoor Mine Surface Facilities Area.

The current mining operations, in the Tahmoor North lease area, are forecast to be completed by 2022.

Tahmoor South proposal - summary

Tahmoor Coking Coal Mine is owned and operated by SIMEC Mining, a member of the GFG Alliance. The mine has been in operation since 1979 and employs around 400 people, almost half of whom live in the local area of the Wollondilly LGA.

Currently the existing mining operation is due to cease in 2022, however, we have made an application to extend the life of the mine by a further 10 years, up until 2032. This extension will ensure the mine continues to provide employment for the community and produce coking coal for the domestic and international steel industry.

The area proposed to be mined beyond 2022 is within an existing mining lease that has been held for the last 30 years. The proposed extension would see operations extend south towards Bargo. The project application to government is therefore referred to as Tahmoor South.

If approved, there would be no significant changes to how the mine currently works. Employees and contractors would continue to work at the existing facility on Remembrance Driveway, Tahmoor, and the coal would continue to be processed using existing facilities and transported to Port Kembla Coal Terminal mainly by rail.

If approved, there will be significant benefits for the local community and broader region.

A total of $664.9 million will be injected into the region and state economies. In the Wollondilly region, this will include benefits of $137.5 million to employees; $32.5 million to local businesses; and $4.7 million to Wollondilly Shire Council in payment of rates.

Tahmoor South proposal - detail

Tahmoor Coking Coal Mine is an existing mine approximately 80 kilometres south-west of Sydney in the Southern Coalfields of New South Wales, within the Wollondilly Shire Council.

Tahmoor Coal is seeking approval for the Tahmoor South Project, an extension of underground mining at Tahmoor, to the south of existing surface facilities. The project seeks to extend the life of mining at the Tahmoor Mine until approximately 2032, extending employment for close to 400 people for a further 10 years.

Coal extraction of up to 4 million tonnes of Run of Mine (ROM) coal per annum is proposed with up to 33 million tonnes of ROM coal proposed over the life of the Project through Longwall mining. This technique for coal extraction has been used by Tahmoor Mine for over 30 years.

Once the coal has been extracted and brought to the surface, it would be processed at Tahmoor Mine’s existing facilities, before being transported primarily on rail to domestic and international customers.

Tahmoor Coal has undertaken extensive stakeholder and community consultation regarding the proposed development since 2012, and takes its role seriously to inform, support and respond to issues that are raised.

The project design has undergone numerous revisions to avoid longwall mining directly under sensitive features such as the Metropolitan Special Area, bedrock rivers with standing pools, items of Aboriginal heritage and significant landscape features such as river gorges.

An Environmental Impact Statement (EIS) was prepared and placed on public exhibition from 23 January 2019 to 5 March 2019, to allow Government agencies, local councils, organisations and community members the opportunity to provide feedback on the project.

Key points raised during this period included concerns relating to the proposed extent of longwall mining, the associated subsidence impacts, greenhouse gas emissions and the extent of vegetation clearing required for the extension of the reject’s emplacement area.

In response to the feedback received, Tahmoor Coal made the decision to revise the proposed extension to reduce the environmental impact of the project while improving the local and regional economic benefits.

Full details of the project are outlined the Tahmoor South Project Environmental Impact Statement (EIS) published on the NSW Department of Planning and Environment website.
