Rehabilitation of former Kangaroo Flat, New Moon, Eaglehawk mining and Woodvale Evaporation Ponds sites
Kralcopic Pty Ltd (Kralcopic), a wholly owned subsidiary of GBM Gold Ltd, previously held mining licences around Bendigo, including the Woodvale Evaporation Ponds Complex and sites in Kangaroo Flat, New Moon and Eaglehawk.
In August 2019, Earth Resources Regulation decided not to renew Kralcopic’s three mining licences, due to the company’s inability to provide surety that it could finance its mining activities and site rehabilitation obligations.
In October 2020, the company filed legal proceedings in the Supreme Court challenging the decision not to renew these licences. The Supreme Court later upheld the regulator’s decision not to renew the licences.
On 23 April 2021, the Federal Court of Australia appointed KPMG as Kralcopic’s liquidators.
On 14 May 2021, the liquidator’s lodged papers with ASIC to disclaim Kralcopic’s freehold land at Woodvale Ponds and parcels of land around the company’s former Bendigo mine sites, with the land reverting to Crown land.
Earth Resources Regulation has put a statutory exemption in place to preclude new mining licence applications on the sites while we rehabilitate the sites. The exemption also provides an opportunity for government to consider future uses of the sites in consultation with the City of Greater Bendigo and the local community.
Earth Resources Regulation holds rehabilitation bonds totalling $5.9 million, which it will use to rehabilitate the former mine sites.
In February 2022, Earth Resources Regulation appointed independent environmental auditors to review the rehabilitation requirements for the Kangaroo Flat and Woodvale sites.
The EPA accredited environmental auditors Niboi Consulting and CDM Smith will review the rehabilitation plans for the Kangaroo Flat and Woodvale sites respectively and provide advice on the work required to return the sites to safe, stable, and sustainable landforms. The auditors’ reports are expected to be received in mid-2022.
Site monitoring and maintenance
Monitoring and maintenance activities are continuing at the former mining sites pending the completion of site rehabilitation.
In September and December 2021, a polymer was applied to the tailings dam at Kangaroo Flat to reduce dust from the site over the warmer months. The area covered is shown in the images below.
The rest of the tailings dam will be covered progressively with rock as part of the site’s rehabilitation works, in accordance with the Kangaroo Flat Mine Closure Plan.
Videos show the application of polymer and no dust movement onsite during windy conditions, demonstrating that the polymer is working effectively.

Dust at the Woodvale Evaporation Ponds Complex is managed through a combination of vegetation, mulch and water cover.
Earth Resources Regulation met with community representatives, the Woodvale Progress Association, onsite in November 2021 to discuss and tour the site.

Specialist environmental firms have been engaged to conduct depositional dust monitoring to ensure that any potential dust issues are being minimised and managed effectively.
The monitoring also gathers baseline data to identify if and where further monitoring and investigation might be required ahead of rehabilitation works.
Samples are taken from multiple locations across the sites, to ensure the data is representative of the conditions of the site. To date, monitoring results show that the data at the sites is comparable with background levels recorded in the Bendigo area.
The dust monitoring reports are available to download for both Kangaroo Flat and Woodvale Ponds.
The former mine sites have been secured with regular patrols, and local service providers are being sought for site clean-up and rehabilitation activities.
Earth Resources Regulation will continue to keep nearby residents and the wider Bendigo community updated about the rehabilitation of the former mining sites.
