The Red River – A mining legacy

The Queen River runs through the historic mining town of Queenstown on the scenic West Coast of Tasmania and is a wild fast moving river that winds through the mountains joining the King River and flows into Macquarie Harbour.

The town is home to the longest running Copper Mine in the world and improvements to the smelting process also were made here.

Unfortunately, however, it became one of the most dangerous mines … being in a temperate zone that receives 3 meters of rainfall every year … and being on a seismic fault line. There have been tragic accidents where too many lives have been lost. The mining and smelting degraded the environment so much Queenstown became famed for the denuded landscapes … and its Red River. The Queen River turns red from the iron oxide that leaches from the mine along with other metal sulphides and most of the creeks around the town are subject to the acid mine drainage and can be consider contaminated.

Acid Mine Drainage is a continuous problem

Historically Queenstown, Zeehan, and Gormanston were bustling mining towns where some 10,000 residents lived. Now with mine closures the town supports just under a couple of thousand residents and Gormanston is almost a ghost town now compared to its prosperous years when several thousand residents lived there when mining was at it peak. Queenstown, the hub of the West Coast, was a mining town … but is now a town with a mine it. There is astounding natural heritage around Queenstown and the mine is an eyesore that decreases property value.

Scenic Queenstown, a from mining town to a town with a mine in it

The mine has been in care and maintenance for several years now; the future is uncertain and contractors and miners have sought work elsewhere. Queenstown is not just a mining town now, it is also a popular fishing destination (Lake Burbury), a growing Arts community with several galleries and studios, and popular tourist destination … and for retirees. There is pristine rainforests such as on the Bird River, wild rivers, lakes and mountains to see and visit and in my book is one of the most scenic areas of Tasmania. The town is nestled in the mountains and is an atmospheric and scenic place. A great place to write a book, take art classes, pottery at the studio, carpentry with the men’s shed, thai chi class, bushwalking groups, fishing trips, craft markets and the like. The historical train gives a sense of history of our cultural heritage and it winds through the remote wilderness mountains to Macquarie Harbour.

Who will pay for the environmental degradation caused by a century of mining history given the company has changed hands so many times? Given the landscape was denuded by acid rain from smelters in the past, it has eroded the topsoil down to the igneous pyrite bedrocks which are high in sulphur and oxidise and leach out metal sulphides when it rains. This is an ongoing disturbance in the Queen and King Rivers, Comstock and Linda Creeks.

The degradation of the landscape from the denuding from acid rain in the past and the ongoing Acid Mine Drainage contaminating natural water courses is significant and ought to be considered a public health risk and addressed accordingly.

Mt Lyle Mine – a century of mining history left a scar on the land

People have come and gone for over a century and certainly left a big imprint on the land. Queenstown environs is regenerating naturally and the Gondwana Pines and rainforest will probably take another 150 years to regenerate. The mine and environs is regenerating slowly. However from a satellite it is easy to see the degradation caused to the region. From Lake Burbury, to the Airfield, to Macquarie Harbour the impact of the acid mine drainage and the acid rain in the past denuding the landscape is profound.

This includes the Queen and the Kind Rivers, and Macquarie Harbour where the tailings were – up until thirty years ago – dumped directly into the river. It also includes the swamplands near the airfield where the tailings are now deposited, as well as contamination of Glover Creek, Comstock Creek, Linda Creek, Lake Burbury and Macquarie Harbour. There was some $9 million allocated for stopping the acid drainage, however, after council did not spend the money the (Rudd) government withdrew the money and apparently it went to the Fox Abatement program (which is another shambles) in Tasmania.

The tailings used to be dumped directly into the river and ultimately ends up in the ocean and the food chain

If the mine ever were to become operational again then there is much opportunity for shallow cut mining from the open cut. Given the fatalities, the seismic and water intrusion it can be considered too dangerous to underground mine. The underground has always been problematic due to the high rainfall, the open cut over the underground concentrating the rainfall runoff … such that it continually has to be pumped out.

The Mt Lyle Underground Mine is Dangerous

Ecologically Sustainable Development is legislated and should be considered at the highest level. This originally included the key principle of internalisation of environmental costs: the polluter pays principle.

The acid drainage can be prevented and treated with cocomatting, cascading detention ponds, seepage beds and restoration of local province plants. The River corridor can be restored with a buffer from the public and the river can be slowed down and various sedimentation points. If funding were available the Macquarie Harbour mouth can be built up and restored. Priority to protecting public health by controlling the acid mine drainage such that it is a no-waste system and only slow groundwater releases to the natural water courses.

Open cut mining offers a sustainable industry whereby the impacts are contained within the local environs. There is a lot of copper and some gold and silver that can be further processed including processing out the gold and silver in the tailings dam. Connecting up the light rail and considering blasting a road through the open cut will help drain out the open cut and reduce water intrusion underground. These solutions are all practical and achievable to control acid mine drainage and mine safely in future.

A Coordinated and Cooperative Approach of managing the whole region where different stakeholders exist is a sensible way to addressing the problems. This is whereby a work party consisting of all the stakeholders can find common goals and begin to address the environmental degradation in the region and get the mine going safely again.

This lessens the ownership of each stakeholder and shares responsibility … given it is a century old legacy.

    I’ve thought about the topic, and the situation with the Devils only on the West Coast now …

    If we can allocate $10 M for rehabilitation. I suggest move the river, remove fences, make a nature corridor and bike path through town, and pipe treated acid mine drainage below the town.

    This way campers can swim and fish along the river, and have it well signed about risks below the mine’s discharge point.

      This sounds like a lot to achieve with $10mill. Is this including the AMD treatment ?

        One would have to do a costings proposal, however $15m would go a long way to treating the AMD and fixing the river.

        Cascading seepage beds, limestone, cocomatting, soil restoration, and bush would all help treat the excess runoff prior discharge to water courses. Moving the river and creating a nature corridor and bike path through town, and piping the mine discharge below the town, will eliminate the public health risks through the town.

    Although giving a generally fair summation of the situation at Queenstown and the mining activities there, this article unfortunately has a few inaccuracies and – the writer hasn’t even managed to spell the name Mt Lyell correctly!

    In compliance with the Environment Protection Act, 1973(Tasmania) and Water Management Act, 1999 (Tasmania) a voluntary non legally binding Environmental Management Plan was devised offering mitigation measures. There has been warning and recommendation about treating the acid drainage since the 1990’s. There is no legal obligation for remediation while the mine operates under care and maintenance.

    The acid drainage contaminates all the waterways around Queenstown affecting fisheries. At Linda Creek a 10 day trout in a cage test showed they died in four days at Linda Creek. That was 1992. Linda and Comstock Creeks were contaminated then and they are now. The other sites around Lake Burbury are apparently alright and they survived the 10 days. http://www.ifs.tas.gov.au/about-us/publications/newsletter-archive/inland-fisheries-commission-newsletter-vol21-no.2-oct-1992

    Dear MJF, in response to your question i don’t know the fine details as i have been wanting a meeting with the mine manager and encouraging community engagement but to no avail. The mine has been in care and maintenance since 2014 following 3 deaths. There is only a legal obligation for remediation once the mine is in closure and whence nothing has been done to address the serious public health and ecological health issues associated with acid mine drainage contaminating all the water courses. Vedanta is a subsidiary of Copper Mines of Tasmania based in London and India and may not have the same sensitivity, care and concern for the environment and the workers as an Australian company. The contamination is a regional issue, community engagement is important and a coordinated and cooperative approach is required. Ideally money could be allocated to control acid drainage and the mine could become operational again shallow mining that which is safer than the underground.

    Rumour has it that the Tasmanian Government is prepared to allocate money to the mine.

    Interesting article Michael.

    What’s the story with rehab bond monies held, bank guarantees, rehab plans, etc presumably administered (or to be administered) by MRT which is the expected process for Tas miners ?

    Is there anything in place or does nothing currently exist/carry over after all this time and various ownership changes ?

    #3. john do you descend from this part of Tasmania or are you just playing real-estate man.

    At differing times Queenstown has had the distinction of a town offering their older era houses at rock-bottom prices both now and before this latest shutdown of Queenstown mine.
    Not withstanding some of these houses were in a bad state of decay when listed for sale.

    What a stupid statement to make, that the environmental degradation reduces property prices. The town would never have existed without the mining and if the mine reopens property prices will rise.

    An excellent summary of the facts by you Peter Galvin, a man of your background and the success you have achieved in your long and successful chosen careers is sorely needed in Tasmania.
    I note you were careful not to point the finger as to the reason this aforementioned river system has been determinedly overlooked and allowed its ongoing environmental degradation.
    My desire to express the unpopular truth will do that for you in my saying that the cause of Tasmania’s West Coast degraded river system lays at the feet of this State’s succession of Liberal/Labor State Premiers and government ministers.
    These gentry prefer to devote their time to perpetuate the trashing of Tasmania’s forested environment via the aegis of a wholly unsustainable broad-scale logging program to the benefit of a chosen small group of twisters, all of whom are destined to achieve the ultimate wipe-out of Tasmania’s once prolific Old Growth Gondwanna-Land forests.
    Currently one of its chief beneficiaries are Ta Ann based in Sarawak

    https://www.globalwitness.org/en/archive/hsbc-rakes-us130-million-bankrolling-rainforest-destruction-and-human-rights-abuses-malaysia/

    Given that the State government do not bother representing the people of Tasmania except for those high-tower elites and big business interests, this grubby group of environment destructors would care little of your suggested environmental repatriation program instead preferring to avoid this matter ever being shown the light of day.

    You are to be commended for your professional approach with you providing your qualified overview necessary to clean up and restore a semblance of our days of yore, this had Tasmania known as a World respected clean green State of excellence.
