The Pentagon Has Spent Nearly $5 Billion Trying to Secure This Metal. A Quebec Explorer Just Drilled the First Hole in 47 Years.

North American Niobium and Critical Minerals Corp. (CSE: NIOB | OTCQB: NIOMF) holds nearly 37,000 hectares in Quebec's Grenville Province and has drilled two holes at its Seigneurie property. The first returned 211 metres of pegmatite. Both assay sets are at the lab.

Breaking

Nobody drilled Seigneurie for 47 years. NIOB went back in April and hit pegmatite in both holes.

The first hole returned 211 metres of pegmatite, the rock that carries niobium and rare earth elements, including a continuous 105-metre central interval. That width ranks 4th among all publicly disclosed intersections of this rock type in the world.

A second hole, put in 50 metres east of the first, returned 108 metres of the same brown mineral assemblage. On-site instruments read niobium, yttrium, and phosphorus. The gamma-ray signal at 162 metres was the strongest recorded anywhere on the property.

Both sets of assays are now at SGS Canada. The company has been trading since November 2025 and the market cap is under $25 million.

GET INVESTOR DECK

North American Niobium and Critical Minerals Corp. (CSE: NIOB | OTCQB: NIOMF)

Most investors have never heard of this company.

You Have Probably Never Heard of Niobium

That is not unusual. Most people have not.

It goes into the steel inside fighter jets, bridges, pipelines, and electric vehicles. Adding a fraction of a percent to ordinary steel turns it into something the aerospace and defense industries cannot build without, and there is no viable substitute.

92% of the world's supply comes from one company, CBMM, operating in a single region of Brazil. The United States stopped producing the metal domestically in 1959 and holds no strategic reserve.

When the Trump administration imposed sweeping tariffs in 2025, niobium was explicitly carved out. A president running the most aggressive trade campaign in modern history decided this metal was too important to include in the tariff list.

In November 2025, the U.S. Geological Survey ranked niobium in the top 10 critical minerals by economic risk to the United States. Two months later, a bipartisan group of lawmakers proposed a new $2.5 billion agency with one purpose: secure America's critical minerals supply chain. The Pentagon had already committed nearly $5 billion the year before trying to solve the same problem.

Finding a North American source for this metal moved from a policy priority to an emergency spending problem.

The One Geological Address Where North America Can Solve This

Quebec's Grenville Province leads every other geological province for critical mineral occurrences and deposits: 1,623, more than any other in the country. CSE: NIOB | OTCQB: NIOMF's five properties sit inside it.

The Grenville Province in Quebec is the only region on the continent that has already proven it can host a world-class niobium deposit.

North America's only producing niobium operation, the Niobec Mine, sits inside it. The Grenville Province carries the specific rock types, structural settings, and mineralizing systems that produce economic niobium at a scale no other part of the continent matches. If more North American niobium gets produced, it will almost certainly come from here.

One Company Holds Nearly 37,000 Hectares Inside It

North American Niobium and Critical Minerals Corp. assembled a district-scale land package of nearly 37,000 hectares across five 100%-owned properties in Quebec's Grenville Province.

CSE: NIOB | OTCQB: NIOMF's five properties (Seigneurie, Seagull, Sabot, Bardy, Blanchette) ring the Niobec Mine, North America's only producing niobium operation, across the same Grenville geology.

The company listed in November 2025. It has been public five months, with no institutional position built and no analyst coverage. The story has not reached most investors.

The market has not done the math yet.

The Drills Are Already in the Ground

C$4.82 million is in the bank. Three properties carry drill permits simultaneously: Seigneurie, Bardy, and Blanchette. The company has planned 10,000 metres across the portfolio before year end.

Seigneurie was drilled once before, in 1978, by a Quebec government exploration crew running a regional program for uranium and thorium. They punched holes, logged the results, and moved on to the next site on their list.

The cores were not tested for niobium or rare earth elements. Those metals were not part of the mandate. The records went into a government archive and sat untouched for the next 47 years.

When NIOB's geological team located those original drill collars in late 2025 and mapped them against modern geophysical data, the mineralized system appeared much larger than the 1978 crew had reason to know. Open in all directions. Never tested for the metals the Western world is now urgently trying to find.

April 2, 2026. First drill into Seigneurie in 47 years.

The hole returned 211 metres of pegmatite, including a continuous 105-metre central interval. That width ranks 4th among the widest intersections of this rock type ever publicly disclosed, anywhere in the world.

A second hole went in 50 metres to the east. It returned 108 metres of cumulative pegmatite with the same brown mineral assemblage linked to magnetite that appeared in the first hole. On-site instruments read niobium, yttrium, and phosphorus. At 162 metres depth, the gamma-ray reading was the strongest recorded anywhere on Seigneurie.

Two holes, 50 metres apart, same mineral fingerprint.

The geometry is also turning out differently than originally mapped. The pegmatite appears to be trending northwest rather than east-west, which changes how the system gets modeled and where the next holes will go.

Assays are at the lab for both holes. Bardy and Blanchette have not been drilled yet. The picture is still expanding.

Low Share Count. Very Few Warrants.

Junior exploration companies often reach the drill stage carrying significant share dilution from their earlier financing rounds. Paper from seed investors and private placements can weigh on the stock for years, absorbing buying pressure before price can move.

CSE: NIOB | OTCQB: NIOMF does not have that overhang problem.

23,580,599
shares outstanding
235,704
warrants
2,350,000
options

That is the full count.

For a company at this stage, that share structure is uncommon. It means the float is clean going into a period when significant news is expected.

The Board Has Done This Before

The people who agreed to put their names on a company say something real about where they think it is going.

Joseph Carrabba sits on the board. His career includes more than two decades at Rio Tinto, followed by the top executive role at Cliffs Natural Resources, one of the largest mining operations in North America. He then joined the board of NioCorp Developments, the best-known publicly traded niobium company on the continent. He came to this company after all of that.

The Honourable Kerry-Lynne Findlay is also on the board. She served as Canada's Associate Minister of National Defence and worked directly on the government's response to the critical minerals supply problem during the period it became a formal national security issue.

Both of those people had other options. They chose to be part of this one.

What the Next Twelve Months Look Like

Junior mining stocks move on news, and NIOB has a clear schedule of near-term catalysts.

Now
Assay results from both Seigneurie holes, confirming grades for the system both holes have now identified.
Q2-Q3 2026
Bardy and Blanchette drill programs begin. Blanchette carries the highest surface grades in the portfolio.
Q2-Q3 2026
Assay results from all three properties, released on a rolling basis as they arrive from the lab.
2026-2027
Maiden NI 43-101 resource estimate, which shifts the story from pure exploration to a quantified deposit. This is typically one of the strongest re-rating events in a junior company's lifecycle.
CSE: NIOB | OTCQB: NIOMF's published Q4-2025 to Q2-2026 schedule. Three properties (Seigneurie, Blanchette, Bardy) are now in the drill-test phase, on plan.

Bardy and Blanchette have not been drilled yet. The resource estimate has not started. Each milestone is a distinct reason for the market to revalue this company.

Where Things Stand Now

Seigneurie assay results have not posted yet. Bardy and Blanchette have not been drilled. No institution has taken a position and no analyst has published coverage.

Nearly 37,000 hectares of Grenville Province ground. Two holes with the same mineral fingerprint, 50 metres apart. A market cap under $25 million. That is the current situation.

8 Things Worth Knowing About This Story

  1. Reason 1: Steel, Aerospace, and Defense All Need Niobium. No Country Has Found a Way Around That.

    A fraction of a percent of niobium added to ordinary steel produces material strong enough for jet frames, bridge cables, pipelines, and EV battery housings. Engineers have looked for substitutes and have not found one that works at scale. One company in Brazil, CBMM, supplies roughly 92% of global demand. The U.S. Geological Survey placed niobium in its top 10 critical minerals by economic risk in November 2025. That same month, the Trump administration exempted niobium from its sweeping 2025 tariffs.

  2. Reason 2: The Grenville Province in Quebec Is the Only Place on the Continent That Has Already Done This.

    Producing a world-scale niobium deposit requires a specific combination of geology that does not appear everywhere. The Grenville Province in Quebec has it. The Niobec Mine, the only niobium mine in production on the continent, sits in the Grenville. Geologists working on new North American supply keep arriving at the same conclusion: if more is going to come from this side of the Atlantic, it comes from here.

  3. Reason 3: Nearly 37,000 Hectares, Five Properties, All Fully Owned.

    North American Niobium and Critical Minerals Corp. built a land position covering nearly 37,000 hectares across five 100%-owned properties in the Grenville Province. Rock samples collected at surface have already returned niobium and magnet rare earth elements including neodymium, praseodymium, dysprosium, and terbium. Both the U.S. and Canadian governments are actively spending to bring these specific materials home. The company went public in November 2025 and has not yet reached a broad audience.

  4. Reason 4: C$4.82 Million in the Bank. Three Properties Permitted. Drilling Has Already Started.

    Capital is funded and three drill permits are active at the same time across Seigneurie, Bardy, and Blanchette. The program targets 10,000 metres across the portfolio before the end of 2026. Seigneurie drew attention first: government records from 1978 showed wide mineralized intervals, but the crews at the time were not testing for niobium or rare earths. NIOB drilled the property for the first time in 47 years on April 2, 2026. The first hole came back at 211 metres of pegmatite, ranking 4th widest for this rock type in any public disclosure globally. The second hole, placed 50 metres away, returned 108 metres with identical mineralogy and the strongest gamma-ray reading on record for the property. Lab assays are in progress. Bardy and Blanchette have not yet been drilled.

  5. Reason 5: 23.5 Million Shares Out. Very Little Overhead Paper.

    23,580,599 shares outstanding. 235,704 warrants. 2,350,000 options. For a company at the active drill stage, that is an unusually tight float. Companies that went through multiple private placements to get this far often end up with two or three times that share count, plus layers of warrants priced at various levels that create selling pressure every time the stock tries to move. That selling pressure is absent here.

  6. Reason 6: The Board Includes People Who Have Run Major Mining Companies and Shaped Defence Policy.

    Joseph Carrabba spent more than 20 years at Rio Tinto, led Cliffs Natural Resources as Chairman, President, and CEO, and then joined the board of NioCorp, the best-known publicly traded niobium company in North America. He added NIOB to that list. The Honourable Kerry-Lynne Findlay served as Canada's Associate Minister of National Defence during the period when critical minerals first became a national security priority. She was helping write the policy, not watching it from the sidelines.

  7. Reason 7: Assays First. Then Two More Drill Programs. Then a Resource Estimate That Changes the Category.

    The immediate catalyst is lab results from the two Seigneurie holes. After that, Bardy and Blanchette both get drilled in Q2-Q3 2026. Blanchette carries the best surface grades in the portfolio. Assay results from all three properties will come in on a rolling schedule through the rest of the year. The target for 2026-2027 is a maiden NI 43-101 resource estimate, which converts the project from exploration-stage to a quantified mineral resource. That transition typically draws a different class of investor and analyst attention.

  8. Reason 8: Assays Still Pending. Most Investors Have Not Looked at This Yet.

    No institutional position has been built. Analyst coverage has not started. The lab results that will confirm or quantify what both drill holes identified have not posted. Nearly 37,000 hectares in the Grenville Province, two holes with the same mineralogy, and a market cap under $25 million. That is where things stand today.
