Why U.S. antimony import reliance matters

91% import reliant.

That is how much of the antimony the U.S. consumed in 2025 came from imports. Two years earlier it was 81%.

→ China supplied 55% of U.S. antimony imports, then banned exports to the U.S. in December 2024
→ Prices more than doubled in a year, to ~$25 per pound
→ U.S. mine production only restarted in late 2025. Canada has none.

About 40% of U.S. antimony goes into ammunition and antimonial lead. Defense demand does not wait for supply chains to catch up.

That is where Howells Lake fits.

Holes 6, 7 and 16 have now traced continuous near-surface stibnite at direct-ship grades in northwestern Ontario, and the zone remains open. With 10,000 m of drilling scheduled for 2026, an initial resource estimate is targeted for Q1 2027.

North America needs an antimony source at home. Critical One is drilling to prove how much Howells Lake can supply.
