More on Acid Mine Drainage

I've been reading more on Acid Mine Drainage... relevant to the sort we can expect of the Prosperity Mine goes ahead.


Need to know more about AMD? just look on the internet.

EARTHWORKS
Denver-based Newmont Mining Co. fined millions for cyanide spill at Ghanaian mine
Panel faults company for failing to prevent accident, delays in notifying authorities
Joint release: EARTHWORKS * WACAM
Accra and Washington, 01/21: Ghanaian authorities are fining Denver-based Newmont Mining millions of dollars for negligently spilling cyanide at its Ahafo gold mine in October 2009, resulting in water contamination and fish kills. A Ghanaian Ministerial Panel that evaluated the spill and its aftermath recommended that the company be fined US$ 4.9 million for failing to prevent the spill or to properly report on and investigate the spill. 
Newmont Mining has been around a long time, they aren't a relative newbie like Taseko Mines, and still they show complete disregard for the environment. Should it matter that they are in a country without adequate environmental protection?

That must depend on the attitude of the mining company. BHP Billiton, for example, is working to extend the same level of environmental practices to all of its operations worldwide, kind like an ISO exersize.  Taseko? Mines? they have certainly never shown this sort regard for the environment at its Gibraltar operation.

The most recent additions to that mine have seen their waste management grandfathered into the old permit, rather than raise the bar to modern standards. Farmers below the mine have spoken for years about hush money paid to those whose cattle drink downstream.

A report on AMD from Alaska states that:
Logarithmic increases in metal levels in waters from sulfide-rich mining environments are common where surface or groundwater pH is depressed by acid generation from sulfide minerals.Acid Mine Drainage and Effects on Fish Health and Ecology: A Review
A logarithmic increase is the sort I showed in a graph the other day. In that case we were looking at surface area as a rock is broken into smaller and smaller pieces. The result of all that extra surface area is skyrocketing levels of metals reaching the groundwater.

Will Taseko build the 1 Billion dollar "pond" liner that the federal review panel suggests it will need to prevent groundwater?

How should we know, they won't say... the company line is, "let us build this mine and THEN we'll plan our mitigation strategy".

Meanwhile, publishers like the Williams Lake Tribune suggest that the mine is being held up by "professional environmentalists" and "obstructionist aboriginal groups", as if these two had nothing better to do than prevent "progress".

I see Taseko Mines is advertising in the Tribune, no doubt to ensure favourable coverage!

Tom Fletcher of BC Local News disses Federal Review Panel












Tom Fletcher writes for Black Publishing, and he recently wrote an article dissing the Federal Review Panel as simply keeping people in Ottawa in business:


...they rearrange the same scientific data into nice big binders in French and English, taking an Ottawa amount of time to do so... B.C. VIEWS: Ottawa make-work costs real jobs
According to Mr. Fletcher, "obstructionist aboriginals" and "professional environmentalists" simply don't want any more mines, pipelines or power projects. Funny, since the TNG is at work on a bioenergy project for the Chilcotin. As Fletcher says,


 They apparently want B.C.’s vast hinterland to depend entirely on taxpayer-funded welfare, supplemented with politically correct public works like hiking trails, all paid for with money borrowed against those of us still lucky enough to work in the private sector, our children and grandchildren.
I despise this sort of  special interest rhetoric, it's simply sycophantic, brown-nosing partisanship, it's Tom Fletcher employed by Black Publishing to dispense nonsense to the masses.






And it works: if you read the comments after his articles, his writings lead to frequent discussions demeaning aboriginal people and their beliefs and values.  Commentors are quick to criticize anyone in opposition to the mine as being anti-free enterprise and pro-welfare bum. Racism lies close to the surface in these discussions, and commentors use stereotypes to paint First Nations people as hypocritical and adverse to modernization.

Gold and Copper Mines in B.C.

Gold and Copper Mines in B.C.

Summary of the Event

Taseko Mines Ltd.’s $800-million copper-gold Prosperity project was environmentally approved of by the British Columbia provincial government during the week prior to January 15, 2010. The Prosperity project, which pumps out copper and gold from the earth, is scheduled for construction this summer as it joins Copper Mountain Mining Corp.’s similar $440-million project. The demand for mining industries has increased recently, as there is more money to be made now than before. Copper is a metal highly demanded by China because it used widely in manufacturing. Back in the 1990s, the price of copper was less than $1 (U.S.) per pound; now, copper is around $3.40 a pound. While environmental controversy and poor relations with first nations communities have slowed development in the past, companies like Taseko Mines Ltd., who now have environmental approval by the provincial government, will be able to carry out their mining activities as demanded. The price of gold is also looking strong, according to the Energy and Mining Minister, breaking $1100 (U.S. per ounce). Now, all there is left to wait for is the approval of the federal government in the next several months.

I added the following comment to her blog:

Hello Alisha,

I appreciate your economic viewpoint on minerals and strategic choices, but where do you account for the environmental impacts of mines like "Prosperity", and the effects they will have on those who live (and have lived) next to them?

I have been following this mine for some time, and created a simple blog to follow the issue: http://prosperity-mine-vs-fish-lake.blogspot.com/

I am amazed at how little the "outside world" cares about what this mine will do to the land, the lakes it is set to destroy, and the aboriginal people who have made use of both for at least 7500 years. It's all stock promotion and strategy, and the "indians" can go to hell because they are hypocritical anyways.

Any thoughts? and when Taseko has not had to make any accounting for how it will care for and repair the land, and ensure the toxic acid mine waste does not reach groundwater or streams, after the mine is finished, who accounts for those costs? What's a hundred million dollars when your tailings pond leaks, the dam breaks, and your downstream fisheries are "impacted"? Who accounts for the cumulative impact on an already threatened salmon population? Who accounts for the risk? And what about already-established rights and title of aboriginal people, especially here where the Xeni Gwet'in people have shown in court they hold title to this land?

A Brief Explanation of Acid Mine Drainage

I've been reading up on acid mine drainage, the thing that will pose the greatest danger to the environment, should Prosperity go ahead.

The rocks that contain the metals Taseko wants also contain chemicals called sulphides. The  plan is to pile waste rock in the tailings pond... you know, where Teztan Biny or Fish Lake is today. The problem with waste rock is that you are taking a massive chunk of bedrock and breaking it into little pieces and bringing it to the surface. Now, instead of having a little bit of rock exposed you have a massive amount of surface, all of which is exposed to air, water and microbes.

I made a little graph of how surface increases as you break something down into smaller pieces...

To quote the Wikipedia entry:
After being exposed to air and water, oxidation of metal sulfides (often pyrite, which is iron-sulfide) within the surrounding rock and overburden generates acidity. Colonies of bacteria and archaea greatly accelerate the decomposition of metal ions, although the reactions also occur in an abiotic environment. 

These microbes, called extremophiles for their ability to survive in harsh conditions, occur naturally in the rock, but limited water and oxygen supplies usually keep their numbers low. Special extremophiles known as acidophiles especially favor the low pH levels of abandoned mines. In particular, Acidithiobacillus ferrooxidans is a key contributor to pyrite oxidation.

In other words, mine tailings are a Pandora's box full of toxic chemical stew. Like nuclear waste (though not radioactive), they will create this toxic stew for centuries. So when critics complain that the environmental effects of a mine last well past the mine's life, this is why.

Mining companies like Taseko don't really address this issue because it would suggest they aren't actually in complete control of the environment they propose to create. And they aren't...

How can the Toxic Stew leave the tailings pond? Easy, it can:
  • leak through the dam holding it back
  • the dam can break (see this link for a list of dam breaks List of Tailings Dam Breaks)
  • enter the groundwater through cracks in the rock

Mine tailings are forever, and turning Teztan Biny into a tailings pond means perching a toxic stew directly 
above what is for all intents and purposes a pristine watershed critical to a broad spectrum of people, animals and ecosystems.

Campbells Rubber Stamp Decision On Fish Lake Denounced By Whites And Natives Alike

Campbells Rubber Stamp Decision On Fish Lake Denounced By Whites And Natives Alike

Tsilhqot'in National Government denounces "rubber stamp" of approval from BCEAO for Taseko Mines project

Monday Jan 18, 2010
 
January 18, 2010, Williams Lake -- The Tsilhqot'in National Government denouced the BC Environmental Assessment Office (BCEAO) decision to grant an evnironmental assessment certificate (EA) to Taseko Mines Ltd. for a proposed massive mine at Teztan Biny (Fish Lake), an area where the Tsilhqot'in Nation holds proven Aboriginal hunting and trapping rights.

http://howbadtherecord.blogspot.com/2010/01/campbells-rubber-stamp-decision-on-fish.html

“I find it ironic that the province claims it has done „due diligence‟ in terms of consulting with First Nations,” stated Chief Ivor Myers, Yunesit‟in (Stone) First Nation. “The Province rejected all of our efforts to meet with them to set up a consultation process that would work for our people and our communities. Despite government and company efforts to put a positive spin on this, we do not agree with the proposal. Investors should be aware that this project is not a done deal.”

The above blog entry has a good article on how Campbell's government has never listened to the concerns of the Xeni Gwet'in or other neighbouring bands about Taseko Mines' Prosperity Mine proposal.
