Highland Critical Minerals: CIRO Steps In Again After 355% Rally Reverses With 30% Plunge

Junior miner Highland Critical Minerals sees wild stock swings, prompting second regulatory probe in six months amid geopolitical and policy-driven critical minerals demand.

Junior miner Highland Critical Minerals has delivered a textbook example of speculative excess, with its stock first rocketing 355% in five sessions only to crash 30% the following Monday. The violent reversal has drawn a second regulatory inquiry in six months from the Canadian Investment Regulatory Organization (CIRO).

On Friday, May 8, the stock closed at C$1.00 on a 64% single-day gain, after swinging between C$0.49 and C$0.74 during the session. By Monday on Tradegate, the shares had collapsed 30% to €0.4480, trimming the company’s market capitalization to roughly €11 million. The three-month run had previously more than quadrupled the stock’s value — a move management itself could not explain.

CIRO formally requested an explanation from Highland after the May 8 spike. The company responded that it was “not aware of any material change in the company’s activities that would account for the recent market movement.” It was the same statement Highland issued in November, when an earlier surge prompted the regulator’s first inquiry. Two such requests in half a year are unusual for a junior explorer with no operating revenue.

Why the frenzy? Two macro currents are feeding the speculative fire. The escalating conflict in the Middle East and crude oil above US$104 per barrel are accelerating the push for secure supply chains of critical minerals. Highland’s projects sit in geopolitically stable Canada — a fact that has drawn investor interest. At the same time, Canada’s federal budget unveiled a “First and Last Mile Fund” of up to C$1.5 billion and a multibillion-dollar sovereign fund dedicated to critical minerals. Exploration spending in the country for these resources rose 4% in 2024 to C$2.1 billion, accounting for more than half of all domestic mineral exploration outlays.

The company itself has streamlined its portfolio. It distributed to shareholders 0.5 shares and 0.5 warrants of Highland Red Lake Gold, a spinout entity. This reduced Highland’s stake in Red Lake from roughly 73% to 17%. What remains are two core projects: a lithium-focused property in northern Ontario and a gold-focused one in Nunavut.

Funding the field work In March, Highland closed a private placement of 1.6 million flow-through shares at C$0.25 each, grossing C$400,000. The proceeds are earmarked for exploration spending on critical minerals, with tax renunciation required by the end of 2026 and expenditure obligations by the end of 2027. The company has said the funds will directly support its upcoming summer exploration program, a key technical milestone.

The weekly volatility of the stock has jumped from 31% to 41% over the past year. Highland plans to start its field season around the end of May. Until first results emerge — or fail to materialize — the share price will remain hostage to external factors. Geopolitical shifts and raw-material sector swings look set to dictate the valuation rhythm for now.
