NEWS → One flagship. A separate path for non-core assets.

Critical One is proposing to spin out its Kenora Uranium Property and its Khan copper and uranium mining-licensed projects in Namibia into a new company, "Critical Two".

→ Howells Lake remains the flagship
→ The funded 2026–2027 exploration program continues, with its budget unaffected
→ Kenora and the Khan copper and uranium projects in Namibia would move into a separate vehicle with their own path forward
→ Critical Two shares are intended to be distributed pro rata to eligible Critical One shareholders
→ Critical Two is expected to seek a separate stock exchange listing

Micon has also been engaged to complete an independent technical review of Kenora as that asset is prepared for its next stage.

For Critical One, the priority remains clear: keep building Howells Lake.

NEWS → Howells Lake’s unique antimony-gold system continues to grow.

Antimony mineralization extended 30 m northeast. Gold continues beneath the East Zone and in the West Zone. And there is still a lot more drilling and data to come.

→ Hole 17: extended antimony mineralization northeast
→ Hole 14: further defined gold beneath the East Zone
→ Hole 9: added near-surface antimony and gold
→ Hole 13: added more gold in the West Zone

Howells Lake has advanced quickly for such an early-stage drill program.

The growing dataset continues to refine the geological model and build toward a potential mineral resource estimate, while also helping define the next steps needed to position Howells Lake for future development.

How big is the East Zone so far? Big enough to measure in football fields.

That is the drilled antimony footprint at Howells Lake's East Zone, as reviewed in the Micon NI 43-101 report released Tuesday. One zone.

Inside it:
→ Holes 6 and 7: peaks of 70.2% and 70.3% Sb
→ Hole 16: 31.5 m at 4.9% Sb, extending the system ~70 m northeast
→ Open to the northeast and at depth

The ongoing 20,000 m program is filling in the rest of this footprint and pushing its edges out.

Next milestone: Howells Lake's first NI 43-101 mineral resource estimate, targeted as early as Q1 2027.

NEWS → Exceptional grade. Expanding footprint. Processing potential. Howells Lake is moving quickly beyond its historical footprint.

Critical One has built a materially larger modern antimony dataset, now independently reviewed by Micon under NI 43-101.

The takeaway:

→ Antimony intersected across 300m+ of strike, from near surface to >200m depth

→ Hole 16 extended the high-grade system ~70m northeast and returned longer mineralized intervals at depth

→ Based on current drilling, Micon supports continuation of the C$9.4M program expanding drilling for an additional 20,000m

As the technical work advances, Critical One can evaluate future processing routes and potential offtake opportunities.

North America needs antimony it does not have to import. Critical One is working to show what Howells Lake could contribute.

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 am******on 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.

NEWS → More near-surface continuity. Longer intervals at depth. New gold.

Hole 16 extended high-grade antimony 70 m northeast and returned:

→ 31.5 m at 4.9% Sb, including 4.0 m at 21.2% Sb
→ 17.0 m at 1.3 g/t Gold, including 3.0 m at 2.0 g/t Gold

Near surface, the high-grade antimony continues. At depth, Hole 16 returned longer mineralized intervals.

Gold was also intersected more than 200 m west in Hole 11, showing it is emerging across more than one part of the system.

Gold adds another potential source of value, while each new result builds the modern drill data moving Howells Lake closer to a current mineral resource.

NEWS → Howells Lake is entering its next technical phase.

With over 7,000 metres completed and the 2026–2027 campaign funded, Critical One is focused on converting exploration success into the data needed to support a potential future mineral resource estimate.

Micon International has been engaged to independently review the technical data, geological interpretations, compliance and resource-definition workflow.

The goal:
→ identify data gaps early
→ support efficient drilling
→ focus exploration capital on defining scale and continuity

Independent oversight strengthens the path toward future resource work.

07/27/2026

NEWS → Howells Lake is moving from high-grade drilling toward a potential processing path.

Drilling showed what is in the ground.

Preliminary metallurgical work is now beginning to show how the antimony may be separated and concentrated.

Four selected Hole 6 samples were tested:
→ antimony is hosted mainly in stibnite
→ 92.8%–99.1% stibnite liberation after grinding
→ no arsenic or mercury-bearing minerals were identified

Recovery and concentrate-quality testing come next, helping determine whether the high-grade mineralization can support a practical path to market.

07/24/2026

NEWS → Critical One Energy announced $6.875 million in additional exploration capital as Howells Lake moves into its next stage of work.

Only halfway through the $9 million 2026 exploration program, strong institutional support now provides runway to keep drilling and advancing Howells Lake to the end of 2027.

That creates a clear pipeline:
→ follow up the strong Phase I results
→ verify more of the historical system with modern drilling
→ expand the mineralized footprint
→ test continuity and scale
→ advance mineralogy, metallurgy and the recovery strategy
→ build toward future resource work

Phase I delivered repeated near-pure stibnite and revealed a broader antimony-gold-zinc system.

Now the company has the financial strength to keep building a more complete picture of Howells Lake.

Most investors still do not know antimony.
But governments and defense supply chains do.

That's why Perpetua attracted billions in financing.
Government-backed capital is now moving into North American antimony supply.

Critical One is not Perpetua today.
But Howells Lake is not starting from zero.
→ High-grade antimony confirmed with modern drilling
→ Multi-element signature including gold and zinc
→ More than 30 km of antimony-gold targets
→ First Nations agreement, 4-star General (Ret.) as strategic advisor, and infrastructure MOU

Perpetua showed what an advanced North American antimony project can become.
Critical One is trying to prove the earlier-stage version.

How large can Howells Lake become?
That is what the 2026 drill program is built to test.
