It’s a long way from the Strait of Hormuz to the bush roads and headframes of Northern Ontario, but in mining, the world has a way of collapsing distance fast. A conflict choking sulphur shipments through one of the world’s most critical maritime chokepoints is now being felt in the margins of mining operations across Canada — and the North is no exception. Wood Mackenzie’s latest warning makes plain what veteran miners already know in their bones: this industry doesn’t operate in isolation, and when global supply chains seize up, the pain lands locally.
Sulphur is the feedstock for sulphuric acid, and sulphuric acid is the lifeblood of hydrometallurgical processing — the chemistry behind extracting nickel, copper, cobalt, and other critical minerals that Northern Ontario sits on in abundance. When sulphur shipments tighten and acid prices climb, the cost side of the ledger gets uglier fast. Add aluminium price pressure into the mix and you have a compounding squeeze on margins that was already thin for many operators navigating a complex permitting and financing environment. For projects in the Ring of Fire corridor or along the Highway 11 and 17 mineral belts, these aren’t abstract numbers — they’re decisions about whether a project advances or stalls.
2026 was already shaping up to be a pivotal year for Northern Ontario mining, with critical minerals demand rising and new project timelines coming into focus. A geopolitical conflict half a world away doesn’t have to derail that momentum — but it does demand that operators, investors, and policymakers pay closer attention to supply chain resilience than ever before. The North has always found a way to adapt. But adaptation starts with clear eyes about what’s actually happening. Click here to read the full story.
