Vault Minerals submits closure-plan amendment for Sugar Zone permit as it targets October 2027 tailings dam completion

Vault Minerals has submitted an amendment to the Sugar Zone mine’s closure plan to Ontario’s Energy and Mines ministry, a key step in restarting the White River-area underground gold operation centered on building a new tailings storage facility. The company is aiming for approval this month so it can begin underground development next month, with the new tailings dam expected to be completed by October 2027 and gold production starting in November 2027. The restart plan calls for annual output of 50,000 ounces over a seven-year mine life, and drilling has lifted ore reserves to 2.3 million tonnes at 5.4 g/t for 389,000 ounces. The mine sits 30 kilometres north of White River and was originally developed by Harte Gold before being acquired in 2022 through Silver Lake Resources, a predecessor company to Vault Minerals.
