Antimony is an essential but overlooked critical mineral used in defense systems, battery technologies, semiconductors, and fire-resistant materials with no effective substitutes.
‍
Over 80% of the global antimony supply is controlled by China and Russia, creating urgent supply chain and geopolitical risks.
‍
Since 2015, antimony prices have surged over 550%, and supply constraints continue to mount.

Critical One Energy offers rare access to this strategic metal through Howells Lake, one of the largest undeveloped antimony-gold systems in Canada, with scale, grade, and expansion potential.
‍
For investors looking for exposure to critical minerals and battery metals, this project offers direct leverage to a material increasingly prioritized for clean energy and national security.

Located in Ontario, Canada, Howells Lake contains a historical resource of 48 million lbs of antimony at a strong 1.4% grade, with additional high-grade gold intercepts.

The deposit remains open for expansion both at depth and along strike.

It is one of the largest undeveloped antimony assets in a Tier-1 jurisdiction, offering investors a unique combination of scale, geological potential, and permitting simplicity.

With infrastructure access and alignment with the Ring of Fire corridor, this project stands out in the global landscape of junior mining companies and critical resource stocks.

Over $4 million in historical exploration in 1979 including drilling, trenching, and geophysical work (equivalent to $15M+ in today’s terms), has already been invested in the Howells Lake Project.

Historic drill intercepts include values as high as 75% antimony and 2.31 oz/ton gold.

While the current resource predates NI 43-101 standards, modern assay confirmation and oversight from industry leaders including Bruce Durham (P.Geo) and original discoverer Chet Idziszek, reinforce the project’s credibility.

The company is actively pursuing permitting and additional drilling to upgrade the resource to NI 43-101 compliance.

The project’s geology suggests room for multiple additional deposits along the 26 km² trend, not just an expansion of the known resource.

Estimates suggest potential for over 300 million lbs of antimony.

A preliminary production scenario envisions 20,000 tonnes of concentrate annually, which could represent US$1 billion+ in potential revenue.

With gold as a secondary resource and rising prices for both metals, Critical One Energy offers investors leverage to a high-demand, underdeveloped market for those seeking early-stage mining investment opportunities.

The company is fully funded for near-term exploration and maintains a clean cap table, free from debt or toxic instruments.

Insiders and management hold roughly 35% of the outstanding shares, reflecting strong alignment with shareholder interests.

With only ~51M fully diluted shares, Critical One has a tight structure. The company’s funding plan includes flow-through financing at a 150% premium, access to government grants, and critical mineral assistance programs.

Led by CEO Duane Parnham, the leadership team has overseen over $5 billion in shareholder value creation, and believe the company is strategically positioned among emerging junior mining stocks in Canada and the U.S..

As with any early-stage resource exploration stock, the main risks include permitting delays, exploration outcomes, commodity price volatility, and market fluctuations.
‍
Critical One Energy tries to actively mitigates these risks through:

→ Strong support from Canadian and U.S. critical mineral strategies
→ Secure Ontario location with ESG-forward policies and First Nations engagement
→ Exposure to a strategic metal with no substitutes and rising global demand
→ Historic datasets and proven geological models reducing technical uncertainty

This balanced risk profile makes the company an alternative choice for investors exploring battery metals, rare earth alternatives, or critical mineral ETFs and stocks.

This is a rare ground-floor investment opportunity in the critical minerals sector:

→ Surging antimony prices driven by Chinese export controls and defense stockpiling
→ A historically known project finally seeing development in a constrained global market
→ Upcoming drill permits and NI 43-101 resource update
→ A management team with billion-dollar exits and strong insider ownership
→ A market cap of ~$15M vs. a multi-billion-dollar addressable market

For investors seeking undervalued mining stocks, exposure to strategic metals, and long-term growth strategy, Critical One Energy offers one of the few publicly accessible antimony investment plays in North America.
