Started draining the water December 2025 apparently
Also promising drill results on how much copper is in the ground still.
It will take two to three years to drain the 35 million cubic meters of water that have accumulated in the Copper Pit in preparation for the restart of the Murdochville copper mine, according to Osisko Metals.
To prevent contamination of the York River and ensure effective dilution, the mining company must adhere to a slow water flow rate of one cubic meter per second as part of its protocol.
The goal is to preserve the habitat and spawning grounds of the Atlantic salmon, for which this river is renowned.
The water from the mine will first be treated and then channeled into three different sedimentation basins before being discharged into the river five kilometers downstream.
The Murdochville subsoil may contain more copper than expected, according to the latest data from Osisko Metals.
The mining company reports a 120% increase in potential copper reserves compared to the previous estimate. This reassessment would make it possible to consider mining 70 million metric tons of copper ore per year over a period of 35 to 40 years.
“That’s why we’re considering a high production rate. We’re talking about 160,000 metric tons per day to make such an operation profitable,” explains Robert Wares, President and CEO of Osisko Metals.
New exploratory drilling is set to begin by early May in order to extend the deposit to the south and southwest. “We plan to continue drilling this summer to fully develop the deposit,” adds Mr. Wares.
The quality is very good and relatively stable. That’s good news.
