Groups opposed to a big new mine in central New Brunswick are demanding that the provincial government scrutinize the project’s latest plans, including changes to a tailings pond and massive earthen dam that would hold back toxic wastewater.
Northcliff Resources, a firm in Vancouver, recently published a summary of a new feasibility study that showed the $1.5-billion Sisson mine would be a big money maker.
The open-pit mine, which would dig up the critical metals tungsten and molybdenum, is supposed to create 500 jobs during construction and 300 jobs when it’s up and running in 2030.
Over the span of 27 years, the mine about 60 kilometres north of Fredericton, would generate taxes and royalties of just under $14.5 billion, the study suggests. For investors, there’s the lure of payback within less than two years.
“I don’t consider this much more than marketing material,” said Tom Cheney, the executive director of the Atlantic Salmon Federation, in an interview last Friday.
“The government should be asking bigger questions about the trade-off. Even if we do take some of this feasibility study at face value, these claims about jobs and royalties, etc., is this worth it? I mean, it is an insane risk.”
Cheney said it wouldn’t be just a few thousand people in the Nashwaak Valley who would be affected if the tailings pond failed. The Nashwaak River drains into the St. John River, home to the cities of Fredericton and Saint John.
“Do you know how many property values would be damaged? It’s a whole third of the province that lives downstream of this mine,” Cheney said.
Advantages of location
Northcliff’s CEO Andrew Ing has promoted the project for a similar reason – proximity. With Fredericton and other nearby communities, such as Juniper, Napadogan and Stanley, within easy driving distance, there would be no need to build a work camp, and it would be easier to lure workers and executives to the area.
The updated feasibility study, which will be released in full on October 15th, also states that a special fund would be created – a bond – that would be worth $210 million by the time the mine closes in 2057 that would pay for ongoing water treatment and other reclamation in perpetuity.
“With the positive results released, I think that de-risks this project even more, which should increase the appetite for investors to participate in the building of this mine,” Ing told Brunswick News last week.
An opponent had a more skeptical view.
“Essentially, the document that Northcliff Resources released is a tool for the company to get it what it desperately needs – investors,” said Allyson Huestis, the executive director of the Nashwaak Watershed Association, in an interview on Thursday. “It highlights the positive aspects to drum up investment for them.”

Huestis and Cheney are part of the Coalition Against the Sisson Mine, which includes several organizations and individuals.
They have an uphill battle: both Prime Minister Carney and Premier Holt have thrown their support behind the project. The premier plans on pushing Sisson to private investors at a Toronto summit this week as one of eight major New Brunswick projects they should back.
Still, the mine’s opponents say the provincial government has a responsibility to scrutinize Sisson. They want it to conduct an independent, third-party study of the updated feasibility study, the same way it examined Northcliff’s first feasibility study in 2013.
That culminated in a report in April 2015 by the consulting firm Amec Foster Wheeler, which concluded that Northcliff had badly underestimated the cost of building a wastewater treatment plant – by 50 per cent.
The old report also said the firm had low-balled the cost of maintaining the site once the mine closed, when the open pit is supposed to slowly fill with water.
An updated review, Huestis said, would likely cost hundreds of thousands of dollars, money a nonprofit like hers just doesn’t have.
“We need the province to hire independent experts who can really look at it in depth,” she said.
Provincial response
Brunswick News asked the provincial government whether it would conduct such a study. A spokesperson for the Department of Natural Resources wrote in an e-mail on Monday that a review would be undertaken, without saying if it would be done by civil servants or outside experts.
“The feasibility study is a business document prepared by the company for its shareholders and potential investors,” Nick Brown said. “As part of the mining lease application process, departmental staff will conduct a thorough review of the study to assess it against the requirements set out in the Mining Act and its general regulation.”
David Sweeney, the mayor of Nashwaak Rural Community, said his council would reserve comment until the full report is released. However, he told Brunswick News they still expected Northcliff and the provincial government to prove the mine wouldn’t pollute the Nashwaak and Tay rivers.
“We welcome jobs but not at any cost,” he said.
The Atlantic Salmon Federation, meanwhile, has embarked on a study of its own, an economic one for the Nashwaak Valley. The organization is paying $20,000 to the Pond-Deshpande Institute at the University of New Brunswick, which should deliver the research by late fall or early winter.
It will examine some of the economic consequences of the mine, including “local people whose businesses could be ruined if there’s a catastrophic breach, such as people working in the outdoors industry,” Cheney said.
The study will also include an inventory of economic assets in the region and the drivers of prosperity.
“And then finally, the study will chart a path for alternatives that work with the ecology rather than against it.”
Cheney doubted Sisson would create anywhere near 300 jobs.
The first version of the feasibility study from 13 years ago also said the mine would need 300 employees, a figure that hasn’t changed.
The updated version mentions the company would optimize operations by using autonomous haul trucks and electric shovels in the open pit.
“We have to keep in mind that these are highly mechanized, highly automated processes,” Cheney said. “It just doesn’t require that much human labour.”

Commentary: No Madam Mayor, we’re not dead yet
by Logan Atkinson, Seniors for Climate Tantramar
Tantramar Mayor Debbie Wiggins-Colwell wearing her chain of office
Whatever you may think about municipal politics and local politicians, it’s hard to argue that Tantramar’s new mayor and council have been sitting on their hands.
Finally, it seems, we’re working towards a solution to the problems that have plagued Sackville Fire & Rescue. At long last, the province has promised to replace the Peck’s Cove Bridge in Rockport, and it appears as though a citizen’s committee will soon be struck to recommend what to do about the Wheaton Covered Bridge.
And while the premier was invited to visit Tantramar for months and months, it took our new mayor and council to get her here to listen to their, and our, concerns. Great!
But, oh, now this!
Mayor Wiggins-Colwell’s Facebook post just a couple of hours after the province announced its approval of the Centre Village Gas Plant has raised urgent questions about how committed this council is to the well-being of our community.
To say her post was disappointing is a gross understatement.
It was uncaring, dismissive and patronizing, and may finally demonstrate what many of us have believed all along – that our municipal politicians simply do not understand the perils posed by the NB Power/ PROENERGY gas plant.
In a nutshell, Mayor Wiggins-Colwell said that we must now roll over, accept the gas plant, believe blindly that the province had our best interests at heart by approving it with certain conditions and that besides, such matters fall outside the town’s jurisdiction.
So in response, let me say this loud and clear: No, Madam Mayor. We’re not about to roll over and we’re not dead yet. Not even close.
Let’s go through her post point by point.
First: “On behalf of Council…” she begins. What does that mean really? Where does the mayor get the authority to make public pronouncements on behalf of council? Any deliberative body requires a resolution to authorize the senior officer to speak on behalf of it.
So, where is the resolution? And when was the public meeting that passed it?
We’d like to see a poll. How many members of council agree with the mayor’s statement?
Second: the mayor’s statement says: “…we recognize the significant public interest” in the gas plant project.
No kidding.
Of course there is significant public interest in this brainless project. The Centre Village gas plant is the most consequential proposal to come forward to this community in generations. If built, it would change just about everything about life on the Chignecto Isthmus, for many generations and maybe irrevocably, for humans, for plant life, for birds and animals.
Significant public interest?” We’re not talking about a dog park here.
Third: “…our residents hold a range of perspectives on the project.”
Huh?
Why is this relevant? Is this mentioned as justification for not doing anything? Is the mayor saying, “Our residents hold a range of perspectives, so therefore council can’t take a stand?”
But the council has already taken a stand by passing resolutions opposing the gas plant not once, but twice. Residents held a range of perspectives then, just as they do now.
Besides, there’s “a range of perspectives” on every issue that comes before council. A bylaw on open fires? A new dog park? A slaughterhouse in the industrial park? What about changing the Mixed Use Zone to allow seven stories in our downtown? Didn’t take long for that change to get approved, despite a demonstrated “range of perspectives.”
Every issue generates debate.
We elect our mayor and council to consider all viewpoints, determine the best interests of the community, and act accordingly. Their job is to show leadership.
Fourth: “…we must move forward with the expectation that all public concerns are reflected in the conditions” attached to the environmental approval.
Madam Mayor, have you read the conditions? Do you realize that many of them are mere window dressing, requiring PROENERGY to follow the law, for example, when of course, it’s required to follow the law in any case, whether it’s spelled out in a fancy list of conditions or not?
In the last 14 months, the arguments in favour of the gas plant have been thoroughly debunked by those of us resisting it.
We’ve enlisted economics experts, climate change experts, energy experts, ecologists, medical doctors, environmental scientists, lawyers. We’ve submitted bundles of documents to provincial officials refuting the proponents’ arguments, and in virtually every case we have received bland non-responses or none at all. Instead, NB Power, PROENERGY and provincial politicians continue to trot out the same tired arguments, over and over, as if our arguments were never made or held no weight at all.
Have you read the list of conditions Madam Mayor? Have you considered how embarrassingly vague they are? How ambiguous? How jam-packed with the apparently unfettered discretion of bureaucrats in Fredericton who, so far at least, seem impervious to anything like logic, caring, or concern for our shared future?
I ask again: Have you really read them?
Fifth: “As the development moves forward, Council’s role is to consider matters that fall within municipal jurisdiction.”
This sounds so much like former Mayor Black’s position, publicly stated more than once, when he said words like “We have no levers to pull,” or just as limply, “We must stay in our lane.”
“As the development moves forward…?” No Madam Mayor, we’re not dead yet.
Councillor Butcher famously suggested at a council meeting that we can’t tell the province what do do, akin to a child telling a parent what to do or an employee telling the boss how to run the company.
Well, let’s get this on the table in the hope that any uncertainty about this subject can be removed: We know that the town is not in a position to veto the Centre Village gas plant. No one has asked council to do this. No one expects such a miracle.
But what do we expect? What is within council’s jurisdiction?
Section 5 of the Local Governance Act sets out the purposes of the municipality. Pretty basic stuff. The fundamentals. The genesis, really, of everything that’s done at our town hall. What does section 5 say?
It says that one purpose of the municipality is to foster the social and environmental well-being of its community. Notice use of the word “foster.” This is an active verb, it requires action, it suggests that the council must identify what is consistent with social and environmental well-being, and then take steps to achieve it.
This is not about passivity, it’s not about staying silent so as not to offend the boss. It’s about having a vision for the future, about the environmental and social well-being of the community, and then about developing a plan to actively foster that well-being.
But what to do if social and environmental well-being is jeopardized? What if the very purpose of the municipality is threatened by an outside force?
Don’t you fight with everything you have?
Don’t you pound your fist on the table and on the doors to the legislature?
Don’t you find every possible forum to advocate for the well-being of your constituents?
Don’t you demonstrate, over and over and over again, in solidarity with your constituents, that you recognize the threat, that you understand your responsibilities, that you will insist time after time that the well-being of your community must be protected and advanced?
Sixth: In her post, the mayor “…encourages residents to rely on official sources of information for updates regarding the process.” At every meeting of council, and in keeping with the meeting protocols set out in the Meeting Procedures By-Law, we sit on our hands, we leave our signs and banners at home, we keep our mouths shut. We are very patient, respectful of those who appear before council, deferential to the rulings of our municipal leadership.
But relying on official pronouncements for information on this debacle? Really? When all we’ve received so far through official channels is bafflegab, doublespeak and mumbofudge? Non-answers to our questions. Deflection. Disingenuous clap-trap.
Are we being encouraged to abandon the organizations we have consulted and recruited across the country on this crazy project? Many of Canada’s (and the world’s) leading thinkers on environmental health and climate change? Some of the top experts on energy economics? Many physicians and ecologists and environmental scientists? In favour of what? Are we being asked to trust the very authorities whose schemes would destroy the Chignecto Isthmus and the futures of our families along with it?
Did you really think this through Madam Mayor? Do you realize what you’re asking us to do?
No, Madam Mayor, we’re not dead yet.
The very essence of life in Tantramar is at stake here, to say nothing of the wider implications for the environment and climate change. The very essence of our community is in jeopardy.
If you don’t think this is something worth fighting for, something sufficiently important for each and every one of us to continue to raise our voices in opposition together, insistently and continuously, then I’m afraid we’ll understand why our municipal leaders avert their eyes when we meet them on the street.
