Kristen Villebrun and Wendy Bush hoped they wouldn't have to pray for Chedoke Creek, but four years after they first raised alarm about the water's condition, they were part of an Indigenous full moon ceremony to do just that. About 50 people showed up near Princess Point on the dark and frigid Monday evening for the monthly ceremony, which was particularly special as it focused on Chedoke Creek. The body of water that runs into Cootes Paradise had about 24 billion litres of sewage and storm water runoff leak into it due to a gate being left open.
An Australian coal company is withdrawing its plan for a mine in the Crowsnest Pass region of the eastern slopes of Alberta's Rocky Mountains. "The coal mine, in our minds, is a no-go," said Peter Doyle, CEO of Montem Resources, which had proposed to redevelop the Tent Mountain site to produce steelmaking coal. In a letter filed Tuesday, Montem Resources asked the Alberta Energy Regulator to end the environmental impact assessment for the proposal.
Environmentalists are raising concerns about the future of Nova Scotia's only operating gold mine. Gold from the open pit at the Touquoy mine in Moose River, N.S., has already been exhausted, so active mining stopped at the end of January. The mine's owners, Australian company St Barbara, say they are now turning their attention to processing stockpiles, which are lower grade ore and less profitable.
Tuesday’s announcement marks only the 14th time in the roughly 50-year history of the federal Clean Water Act that the EPA has flexed its powers to bar or restrict activities over potential impacts to waters, including fisheries. EPA Administrator Michael Regan said his agency’s use of its so-called veto authority in this case “underscores the true irreplaceable and invaluable natural wonder that is Bristol Bay.”
In the 279 page assessment, the authors outlined a number of concerns including, “Effects on fish and fish habitat resulting from the harmful alteration, disruption or destruction of habitat, particularly due to the gradual drying up of Kapisikama Lake, hydrological changes to the watercourses and changes in water quality,” the assessment said and added, “Effects on the wetlands due to their destruction or disturbance, caused by the development of mine infrastructure and the drawdown of the water table.”
The New Brunswick government could face an annual bill of around $1 million to keep water treatment going if a buyer doesn't scoop up Caribou zinc mine near Bathurst. Tom MacFarlane, the deputy minister at the Department of Natural Resources and Energy Development, offered the estimate to MLAs during a committee meeting recently in Fredericton.
Debby Rideout had her whole future ahead of her. In August 1987, Rideout had just gotten married, and was already hatching plans to open her own hair salon. Just two days after her wedding, which crammed a hundred revellers into a nearby Lions Club hall, she moved from her hometown of Twillingate to picturesque Moreton’s Harbour, into a cozy wood-panelled home she built from the ground up with her husband, Chris.
The U.S. Environmental Protection Agency on Thursday proposed restrictions that would block plans for a copper and gold mine in Alaska's Bristol Bay region that is home to the world's largest sockeye salmon run. A statement from the regional EPA office said discharges of dredged or fill material into the waters of the U.S. within the proposed Pebble Mine footprint in southwest Alaska would "result in unacceptable adverse effects on salmon fishery areas."
In an expansive open-air pit 550 kilometres northwest of Montreal, 100-tonne trucks criss-cross the climbing roads, preparing for the mine to open. The chalk-white veins of those rocks have metals inside, including one of the most sought-after minerals in the world: lithium, a key component of electric car batteries. When production restarts at the La Corne, Que., lithium mine early next year, it is set to be one of the only functional lithium concentrate mines in North America and position Quebec as a Canadian lithium leader.
Water licences are required for most mining operations and typically come with a number of conditions, which may include a requirement to provide a security cash deposit so funds are available for clean-up and remediation efforts should anything go wrong. Every two years, mining companies are required to submit reclamation and closure plans, to ensure sufficient security. Buchan said Victoria Gold hasn't been in compliance with that process, pointing to a lack of information on adjustments to its heap leach pad involving certain recontouring work, and apparent snow removal obligations from that site.
Towedo, along with other First Nation chiefs at the ceremony, made reference to the mine being a steward of the land, ensuring it protects water and other natural resources. The mine will relocate tailings from a former tailings site for the McLeod-Mosher and Hardrock Mine. The movement of the tailings is slated to actually improve water quality in neighbouring Kenogamisis Lake, and reduce the amount of arsenic in Barton Bay and the Central Basin.
Findings from a study describing the arsenic legacy left in lake-bottom sediments near an abandoned Halifax gold mine are setting off alarm bells for a senior cancer researcher. A paper published Monday in the journal Science of the Total Environment says a dated core sample taken from the bottom of Lake Charles discovered arsenic at 4,960 milligrams per kilogram, more than 280 times higher than levels "where biological harm is expected."
When Barbara Sherwood Lollar sent water samples to a colleague at the University of Oxford for testing, she knew this was no ordinary water. The geochemist had spent much of her career wandering around some of the deepest mines in the world, finding and extracting water that was millions of years old. She waited and waited for results that should’ve come back promptly. So she dialled up the U.K. researcher in charge of the test. “I said, ‘Hey, what’s going on with the samples?’ ” she recalls. “He said, ‘Our mass spectrometer is broken. This can’t be right.’ ” The tests pegged the mean age of the samples, extracted from a mine north of Timmins, Ont., in 2009, at 1.6 billion years old—the oldest ever found on Earth.
Life found in ancient water flowing through a northern Ontario mine could eventually help scientists unlock the mystery about whether there was ever life on Mars, according to a scientist at the University of Toronto. Barbara Sherwood Lollar, a professor of geochemistry, led a team of researchers at the Kidd Creek mine north of Timmins, Ont. that extracted the oldest sample of water ever found – almost 2 billion years old – from 2.4 kilometres underground.
