Canada’s Arctic Infrastructure Bet and a Second CIRO Probe: Highland Critical Minerals Enters Summer Under a Cloud

Junior explorer Highland Critical Minerals sees 80% stock plunge, two CIRO inquiries, while federal Arctic funding for Grays Bay road and port may benefit its Nunavut property.

While Ottawa funnels tens of millions into Arctic infrastructure to spur critical-mineral development, Highland Critical Minerals finds itself mired in regulatory uncertainty and a volatile stock that has shed the bulk of its value. The junior explorer is set to launch a summer field program on its Church lithium property in northern Ontario at the end of May, but the stock’s recent gyrations have raised eyebrows at Canada’s investment regulator.

The share price currently sits at C$0.22, a level that is roughly 80% below its 200-day moving average. That bleak technical picture stands in stark contrast to the bullish backdrop: the federal budget includes a multi-billion-dollar Critical Minerals Sovereign Fund, and a First and Last Mile Fund with up to C$1.5 billion. On May 22, the government also announced more than C$55 million for two major Arctic infrastructure projects in Nunavut, including up to C$50 million for the Grays Bay road and port – a development that could directly lower logistics costs for Highland’s Sy property in the same territory.

Yet the company’s equity has been hammered by two distinct episodes of extreme volatility that each drew attention from the Canadian Investment Regulatory Organization (CIRO). The first occurred in early May, when the stock rocketed 355% over five trading sessions to C$0.61. CIRO demanded an explanation for the surge, asking whether the company had failed to disclose a material business development. Highland denied any such event. The next trading day, the shares plummeted roughly 47% to C$0.31, and that triggered a second CIRO inquiry – an unusual occurrence for a junior explorer without operating revenue.

That was not the end of the turbulence. A later rally pushed the stock to a historical high of C$1.02 before a sharp reversal on May 21 wiped out 38.3% of the value in a single session. The combined damage from the two crashes has left the market deeply skeptical of the company’s near-term prospects.

Highland’s financials offer little reassurance. The company posted a net loss of approximately C$559,000 for fiscal 2025, and it has yet to produce a National Instrument 43-101 compliant resource estimate. Management has set a target of late 2026 for that milestone.

The operational focus this summer is the Church property in northern Ontario. Starting in late May, the company will conduct radiometric surveys, LiDAR mapping, and a sampling program designed to identify lithium-rich zones. The exploration push is financed by a non-brokered flow-through private placement that raised C$400,000 through the issuance of 1.6 million shares at C$0.25 each. The decision to use airborne geophysics reflects a strategic shift: a previous mobile-metal-ion soil test failed to detect significant lithium anomalies.

Beyond Church, Highland holds the 3,345-hectare Sy property in Nunavut’s Yathkyed Lake Greenstone Belt, and a 3,366-hectare property at Red Lake in Ontario. The gold interests at Red Lake were spun out into a separate entity in December 2025, with Highland shareholders receiving 15.6 million shares of the new company.

The regulatory spotlight is likely to remain intense. A report published on May 21 titled “The Data Deficit” criticised Canada’s approach to critical minerals and called for greater transparency in supply-chain data – a development that could stiffen the scrutiny applied to projects such as Highland’s. Meanwhile, chart watchers note that the stock has fallen below its 50-day exponential moving average, with support near C$0.18 and a resistance band between C$0.44 and C$0.47, a level where the shares had consolidated in mid-May.

With fieldwork about to begin, the next few weeks will be critical. For a company that has delivered little in the way of concrete exploration results and is now fielding two regulatory inquiries in six months, the summer data will need to provide a strong narrative – or the stock will remain at the mercy of momentum and technicals.
