Little Salmon Carmacks First Nation takes mine remediation complaints to water board

Little Salmon Carmacks First Nation takes mine remediation complaints to water board

The Little Salmon Carmacks First Nation (LSCFN) claims that remediation work at an abandoned mine site in its traditional territory is only making things worse and so they are asking the Yukon Water Board to step in and change things. The subject of LSCFN’s complaint is the Mount Nansen mine site, a former gold and silver project located west of Carmacks that was heralded as an environmental disaster and an embarrassment to Canada, the Yukon and the mining firm involved when it was abandoned in 1999.

Miners Find 2 Billion-Year-Old Water Reserve and There Is Something Living in It

Miners Find 2 Billion-Year-Old Water Reserve and There Is Something Living in It

Water is regarded as the second most important source of life, behind air, which most organic life requires constantly. The oldest water in the world is found in Canada, specifically the Kidd Creek mine in northern Ontario. In 2016, researchers discovered what is thought to be the oldest water, estimated to be at least 2 billion years old, but more likely 2.7 billion. The circumstances at the mine's bottom have been ideal for preserving the water. This ancient water was discovered at a depth of 2.5 kilometers (1.5 miles) because the Kidd Creek mine is the world's deepest basal metal mine, holding numerous metal minerals such as copper, zinc, and silver.

New Brunswick takes control of Caribou mine as owner goes into receivership

"Private contractors will be hired to maintain essential site operations with the majority of their work being water treatment and ongoing monitoring." Chaleur Shotcrete Inc. and Stantec are the primary contractors, the province said Thursday. Brown said ongoing water treatment is required at the Caribou and Restigouche mine sites because water that contacts rock at the locations becomes acidic, something that poses environmental risks if untreated.

Former mine site at Pine Point, N.W.T., 1 step closer to seeing new mine open

Former mine site at Pine Point, N.W.T., 1 step closer to seeing new mine open

Pine Point, N.W.T., could have a fully operational lead and zinc mine within the next five years — nearly four decades after the old mine closed down and the nearby community was abandoned. In 2022, Pine Point Mining Limited received its Type A water licence, allowing it to withdraw water to be used for mineral exploration drilling, camp use, dust suppression and testing, among other things. 

Teck Doubles Water Treatment Capacity at Elkview Operations

Teck Doubles Water Treatment Capacity at Elkview Operations

Teck Resources Limited (TSX: TECK.A and TECK.B, NYSE: TECK) (“Teck”) Teck announced today that commissioning is now underway at its Elkview Saturated Rock Fill (Elkview SRF) expansion, which doubles the water treatment facility’s capacity to 20 million litres of water per day. The Elkview SRF has been achieving near complete removal of selenium and nitrate from up to 10 million litres of water per day since 2018 and is part of Teck’s ongoing work to implement the Elk Valley Water Quality Plan (EVWQP). The goal of the EVWQP is to maintain the health of the watershed in the area of Teck’s B.C. steelmaking coal operations.

A TALE OF THREE WATERSHEDS: WHAT WE KNOW — AND DON’T KNOW — ABOUT THE HEALTH OF CANADA’S FRESHWATER

A TALE OF THREE WATERSHEDS: WHAT WE KNOW — AND DON’T KNOW — ABOUT THE HEALTH OF CANADA’S FRESHWATER

Canada is famously home to 20 percent of the world’s freshwater — but how well are we stewarding this supply? WWF-Canada recently reassessed the health of our country’s 25 watersheds to better understand how they’re responding to threats from pollution, habitat loss and climate change. Our 2020 Watershed Reports found that 26 per cent of Canadas’s 167 sub-watersheds received a score of Good or Very Good, which is good or very good news! But what’s bad, or possibly very bad, is that nearly 60 per cent of these sub-watersheds received no score at all because they remain Data Deficient. In other words, we just don’t know. This lack of data is concerning as we need a complete picture to determine which areas need dedicated efforts to protect our freshwater ecosystems.
