When Premier Tim Houston recently raised the idea of reconsidering the province’s ban on uranium exploration, the suggestion could have left some individuals scratching their heads.
In any case, it is virtually historic historical past. Nova Scotia has had a moratorium on exploration for almost 45 years, and an outright ban for greater than 15 years. Some youthful residents could not know a factor concerning the subject.
So what’s all of the fuss about? How did we get thus far, and what might come subsequent?
What led to the ban
Though uranium-bearing minerals have been recognized in Nova Scotia way back to the early twentieth century, there have been solely sporadic exploration efforts made earlier than 1976.
However when the Geological Survey of Canada launched a examine that 12 months displaying promise for exploration, firms rushed to stake their claims. The quantity of land lined by uranium exploration licences greater than doubled by the next 12 months to cowl greater than 800,000 hectares in Nova Scotia.
The frenzy was exacerbated by Europe’s curiosity in new vitality sources. Uranium is used within the nuclear vitality trade, in addition to for nuclear weapons and in drugs.
Marilyn Manzer was residing on a farm in Decrease Burlington, N.S., when she heard {that a} French firm wished to mine uranium on the headwaters of the close by Avon River in Hants County.
“We did not know something about uranium on the time. We determined to start out investigating it.”
Native residents fashioned a gaggle known as Citizen Motion to Shield the Atmosphere. Members networked with scientists, medical doctors and activists, with some spending hours in college libraries poring over scientific periodicals to know the newest developments.
Public concern led the province to launch an inquiry into the trade.
Forty-four public meetings have been held all through the province, and the overwhelming majority of audio system voiced opposition to uranium exploration and mining.
Residents and organizations raised issues concerning the potential for damaging well being results resulting from radioactivity, the affect on miners’ well being, contamination of water and air, the potential for a tailings pond or dam leak, and the impact on agriculture and wildlife, amongst different points.
“It was fairly intense,” Manzer says. “The individuals who got here to the conferences have been very critically involved concerning the well being and environmental risks to Nova Scotia from this follow. And lots of people got here as a result of they wished to study it. After which once they did study it, they bought energetic, and began agitating to attempt to get it stopped.”
In 1981, public strain prompted the provincial authorities to declare a moratorium on uranium exploration and mining, and in 2009 the NDP authorities legislated a full ban.
Each have been seen as victories by those that had pushed for a halt to actions.
However one other camp says it is time for the ban to finish.
Trade assist
The Mining Association of Nova Scotia says many individuals have misconceptions about uranium.
“Their understanding of uranium comes from motion films the place uranium is painted as a villain for the sake of Hollywood storytelling,” says Sean Kirby, the chief director. “The fact is it is a necessary materials that all of us profit from, and that mining it and dealing with it’s a completely secure and environmentally accountable exercise.”
There have been “enormous leaps” within the science and expertise of uranium mining in latest a long time, Kirby says.
He says most uranium as we speak is mined in such a means that there are not any tailings ponds — areas the place waste materials is saved, normally in above-ground pits. Some operations now are largely mechanized, and the equipment that extracts the uranium is operated remotely by staff who will not be instantly uncovered to the fabric.
Erin Adlakha, an affiliate professor of geology at Saint Mary’s College, says uranium mining is the most secure mining follow in Canada as a result of stringent environmental laws enforced by the Canadian Nuclear Security Fee. The CNSC publishes reports on the protection of Canadian uranium mines and mills.
“They guarantee that all environmental dangers are thought of, monitored and controlled and so they additionally guarantee employee security and likewise the remediation of mine websites,” says Adlakha, who collaborates with the federal and different provincial governments to analysis uranium deposits.
Adlakha, too, wish to see the ban lifted. She says leaving uranium within the floor can result in it leaching into groundwater, together with consuming water.
She stated the ban additionally stifles exploration of different vital minerals, since they’re usually discovered alongside uranium deposits. Beneath the ban, if uranium is present in portions larger than 100 elements per million, exploration should cease, even when the corporate wasn’t really looking for uranium.
“That 100 ppm cutoff is extraordinarily low,” Adlakha says. “It is unreasonable — barely above background ranges — and there is no science based mostly in that quantity. It is simply an arbitrary cutoff.”
How a lot uranium is in Nova Scotia?
Simply how a lot uranium Nova Scotians are sitting on is unknown.
“We actually had our efforts at uranium exploration nipped within the bud again in 1981,” says Kirby. “So we will not say definitively whether or not Nova Scotia really has any economically viable deposits.”
However based mostly on Adlakha’s examine of historic exploration and knowledge, in addition to Nova Scotia’s geology, she believes the prospects are promising.
“The place we’ve got this granite that’s of the correct kind to supply uranium deposits overlain by this sandstone that might have marine waters which can be nice for dissolving and reprecipitating uranium, it is the right geological surroundings to kind giant uranium deposits.”
She likens Nova Scotia’s geological setting to that of the Athabasca Basin in northern Saskatchewan and the Olympic Dam deposit in Australia, that are two of the world’s high producers of uranium.
Some identified hotspots in Nova Scotia embody a swath stretching from the Annapolis Valley via the inside of the province towards Halifax County, in addition to the Pugwash space.
The Saskatchewan expertise
Nova Scotia will not be the one province to ban uranium exploration or mining. British Columbia and Quebec even have bans, in addition to different jurisdictions internationally.
However one other provincial authorities in Canada has embraced the trade. Saskatchewan has been residence to uranium mines for the reason that Nineteen Fifties, and the present mines operated by Cameco and Orano produce about 20 per cent of the world’s uranium supply, and embody the world’s highest-grade uranium mines.
The mines generated $1.6 billion in gross sales in 2023, and contributed greater than half a billion {dollars} to the provincial GDP in 2022.
The trade will not be, nevertheless, with out its critics.
Ann Coxworth is a nuclear chemist by coaching and has been concerned with vitality and environmental organizations in Saskatchewan for many years.
She says a few years in the past, the hazards weren’t properly understood, and “actually dangerous errors have been made,” similar to dumping tailings instantly into lakes. These practices led to contamination in watersheds that exists to at the present time.
Coxworth says newer mines are extra cautious, and expertise has superior through the years. Some proposed mines in Saskatchewan would see tailings blended with cement and saved underground within the mine, whereas others would see solely the uranium dropped at the floor, leaving the whole lot else beneath floor.
However she and others nonetheless fear concerning the long-term potential for contaminants to flee containment.
“We preserve worrying about what the scenario goes to be 500 years from now, and that is one thing that the regulators merely can not deal with, as a result of there are simply too many unknowns.”
Coxworth gives this recommendation as Nova Scotia faces a possible future in uranium: “I might say be very cautious. Do not enable issues to be rushed. Be ready to take the time to do all the obligatory session.”
What’s subsequent?
Manzer says she feels betrayed by the potential of uranium exploration returning to the province, including that Houston’s assertion that he wants to “take the ‘no’ out of Nova Scotia” by pushing for extra pure useful resource improvement casts her earlier efforts in a damaging mild.
“We have been working our butts off, actually, to be constructive and to guard this province,” she says. “I am shocked to see this factor rearing up once more.”
Even when the federal government decides to open the province to uranium mining tomorrow, “there’s no person beating down our door,” says the Mining Affiliation of Nova Scotia’s Sean Kirby.
“What it’s a must to do is raise the ban and hope that lifting the ban helps appeal to curiosity in our uranium. Definitely there’s curiosity globally to find extra uranium deposits,” he says.
When requested lately if a change to the ban was coming, Atmosphere Minister Tim Halman told reporters to “stay tuned.”
The spring sitting of the legislature — and the primary sitting of Tim Houston’s Progressive Conservative supermajority — started Friday.
