Highland Critical Minerals’ Stock Rout Won’t Stop—Now It Must Prove Its Lithium Story in the Field

After a 355% surge and subsequent crash, Highland Critical Minerals begins a geophysical survey on its Church lithium property to validate targets amid regulatory scrutiny.

After a dizzying 355% surge in five sessions that prompted a second regulatory inquiry in as many weeks, Highland Critical Minerals is finally turning the page from pure speculation to scientific reality. The Canadian junior is poised to launch its maiden modern geophysical survey on the Church property in Northern Ontario, a campaign that will determine whether the lithium pegmatite targets have legitimate geological heft—or whether the recent price action was built on air.

The fieldwork, scheduled to begin in late May pending weather, covers 5,526 hectares across 261 claims. A radiometric airborne survey, LiDAR geophysics, and additional soil sampling will mark the first time the company applies modern exploration tools to the project. Previous rock-chip assays failed to produce significant lithium anomalies, raising the stakes for the coming data release.

A cliff dive for the stock

The share price has been anything but stable in recent weeks. After rocketing to an intraday high of 0.74 CAD on May 8, the stock reversed sharply. On May 12 it crashed to an intraday low of 0.29 CAD before closing at 0.33 CAD. A brief bounce to 0.44 CAD two days later proved fleeting, and by May 22 the stock had slumped to 0.22 CAD—roughly 80% below its 200-day moving average and about half its year-to-date value.

That brutal re-rating followed a staggering collapse from the all-time high of 5.82 CAD set on November 12, 2025. The record low of 0.13 CAD was touched just a few weeks ago on April 28, 2026. The volatility drew the attention of the Canadian Investment Regulatory Organization (CIRO), which asked the company to explain the sudden rally. Management stated it was unaware of any operational changes that would justify the move—the second such request in a short period.

A funded program, but geological risk remains

To finance the summer work, Highland raised 400,000 CAD through a non-brokered flow-through private placement. A total of 1.6 million shares were issued at 0.25 CAD per unit. The proceeds are earmarked for eligible Canadian exploration spending, with tax benefits flowing to investors through the end of 2026 and the spending deadline running to end-2027.

The Church property is targeting lithium-cesium-tantalum mineralization hosted in Archean metasediments, granites, and pegmatites. The company also holds the Sy property in Nunavut’s Yathkyed Lake greenstone belt—four claims covering 3,345 hectares where historical work has identified more than 40 high-grade gold occurrences along a 30-kilometer trend, with surface samples grading up to 38.8 grams of gold per tonne.

Political tailwinds and a sector in motion

Highland is not operating in a vacuum. The Canadian federal government has launched a “First and Last Mile Fund” worth up to 1.5 billion CAD, complemented by a larger sovereign wealth fund dedicated to critical minerals. Domestic exploration spending in the critical minerals space rose 4% in 2024 to 2.1 billion CAD, accounting for more than half of all Canadian mineral exploration.

The broader mining industry is also seeing a pickup in M&A activity, particularly around battery metals and rare earths, as governments worldwide push to secure supply chains.

What comes next

The next few weeks will be decisive. Highland must deliver initial geophysical results that can be translated into drill targets if the stock is to find a floor above its recent lows. If the data confirm lithium potential, the speculative energy that drove the May spike could return in a more sustainable form. If not, the stock may continue to drift toward its all-time low.

For now, the 0.22 CAD level represents a critical support. Whether it holds depends entirely on what the LiDAR and radiometric surveys reveal about what lies beneath the bush in Northern Ontario.
