Tamarack’s Vault Zone: A World-Class Nickel-Copper Discovery Rivaling the Legendary Deposits
Talon Metals Reports Drill Results That Place Minnesota Project Among Global Elite
We previously wrote on July 30 about Talon being a Voisey’s Bay and maybe better.:
“Why this Tesla-backed U.S. nickel project might be the next Voisey’s Bay
Then management said in November 2025 stated ““Geophysically speaking, the initial borehole electromagnetic (BHEM) results from the Vault Zone appear analogous to the geometry of the Reid Brook Zone at Voisey’s Bay, where I worked for over five years,” said Brian Bengert, Talon’s VP Geophysics”
In an era where the United States is scrambling to secure domestic sources of critical minerals, Talon Metals Corp. (TSX: TLO) has delivered drill results from its Tamarack Nickel-Copper-Cobalt Project in Minnesota that can only be described as exceptional. The latest assays from the newly discovered “Vault Zone” place this deposit in rarified air—comparable to the world’s most legendary nickel-copper sulphide discoveries.
The Numbers That Matter
Drill hole 25TK0563B intercepted 8.85 meters grading 9.60% Ni, 12.65% Cu, 0.09% Co, 11.44 g/t Pd+Pt, and 11.12 g/t Au (20.96% NiEq or 41.43% CuEq) starting at 774.40 meters depth.

Drill hole 25TK0563B Intercepted 8.85 Meters of Mineralization Starting at 774.40 meters, Grading 9.60% Ni, 12.65% Cu, 0.09% Co, 11.44g/t Pd+Pt and 11.12 g/t Au (20.96% NiEq or 41.43% CuEq)
Within this intersection, a 6.33-meter core section assayed even higher: 27.28% NiEq or 54.56% CuEq.
This latest hole was drilled just 16 meters northwest of the June 2025 discovery hole (25TK0563), which intercepted 34.9 meters grading 28.88% NiEq and 57.76% CuEq—one of the highest-grade nickel-copper massive sulphide intercepts ever reported globally.
Talon has now delivered multiple high-grade intercepts in the Vault Zone, demonstrating both lateral and vertical continuity of mineralization.
Global Benchmarking: How Tamarack Compares
Voisey’s Bay, Canada
The legendary 1993 discovery hole at Voisey’s Bay intercepted 29.2 meters grading 2.85% Ni and 1.68% Cu.
Tamarack’s 25TK0563: 34.9 meters at 14.86% Ni and 15.37% Cu.
As outlined in the Company's June 5, 2025 press release, drill hole 25TK0563 intercepted a combined 34.9 meters of Massive Sulphide Unit ("MSU") mineralization grading 28.88% NiEq and 57.76% CuEq starting at 762.34 meters. Talon is pleased to report that drill hole 25TK0563B, drilled 16 meters to the northwest of drill hole 25TK0563, intercepted 8.85 meters of MSU starting at 774.40 meters, which assayed 9.60% Ni, 12.65% Cu, 0.09% Co, 11.44g/t Pd+Pt and 11.12 g/t Au (20.96% NiEq or 41.43% CuEq) with full results as follows in Table 1.
Tamarack’s grades are 5x higher in nickel and 9x higher in copper.
Norilsk, Russia
The world’s largest nickel producer, with typical massive sulphide zones grading 8-15% nickel. Talon’s Chief Exploration Officer, Brian Goldner, has explicitly drawn comparisons between Tamarack’s geological model and Norilsk’s “pooling” style of mineralization.
Tamarack’s best intercepts match or exceed Norilsk’s typical grades, with significantly higher copper and precious metal credits.
The Verdict
These drill results place the Tamarack Vault Zone in the top 1-2% of all nickel-copper-PGE sulphide intercepts ever reported globally.
Why the Copper and Precious Metals Matter
At current metals prices (January 30, 2026: $8.39/lb Ni, $5.92/lb Cu, $4,893/oz Au, ~$1,000/oz Pt+Pd), the copper, gold, platinum, palladium, and silver credits significantly enhance project economics. At Tamarack, copper grades of 12-15% make it nearly a co-product, not just a byproduct.
Gold grades of 9-11 g/t and combined platinum-palladium grades exceeding 20 g/t are extraordinary for a base metals deposit. These credits dramatically improve economic robustness and provide a hedge against nickel price volatility.
Each vertical meter of drill core in hole 25TK0563B contains an estimated $85,000-$90,000 USD in gross in-situ metal value at current prices. The full 8.85-meter intercept represents roughly $750,000-$800,000 per drill hole meter.
Market Context: Metals Volatility and Project Resilience
The precious and base metals markets experienced extraordinary volatility in late January 2026. Gold surged to $5,602/oz before crashing 11% to $4,745/oz on January 30. Silver plummeted 31% in its worst day since 1980. Copper hit record highs of $6.58/lb before pulling back to $5.92/lb.
Nickel spiked to $19,000/tonne throughout January on Indonesia’s announced production cuts before settling around $18,500/tonne—still 23% above 2025 averages.
Despite this volatility, Tamarack’s investment thesis strengthens:
1. Nickel Prices Remain Structurally Elevated
Indonesia—which produces two-thirds of global nickel—cut 2026 ore production quotas from 379 million tonnes to 250-260 million tonnes. This represents a structural shift from volume-maximization to price discipline, with Indonesia effectively acting as “ONEC” (OPEC for nickel).
2. Copper Fundamentals Remain Strong
Data center demand alone is expected to surge from 110,000 tonnes in 2025 to 475,000 tonnes in 2026. The market is entering a deficit after two years of surplus.
3. Project Economics Resilient Across Price Scenarios
Tamarack’s ultra-high grades (20-28% NiEq) provide enormous cushion. At current prices, in-situ value is $85,000-$90,000 per meter. Even at conservative long-term prices (Ni: $15,000/t, Cu: $10,000/t), in-situ value remains ~$65,000-$70,000 per meter.
4. Strategic Premium Intact
The $135M in committed government funding reflects national security imperatives that transcend commodity cycles.
5. Nickel Price
The nickel price has broken out on a long-term basis, and we are still well below the all-time high in nickel
6. Talon Share Price
Share price remains in an upward channel. Buy on dips
Continuity: The Critical Factor
Talon has systematically demonstrated that the Vault Zone is a robust, continuous mineralized system:
Lateral Continuity:
25TK0563B (16m northwest): 8.85m @ 20.96% NiEq
25TK0563C (16m southwest): 8.26m of mineralization (assays pending)
Open in all directions with drilling planned north and east
Vertical Continuity:
25TK0565: 19.11m @ 6.39% NiEq, 103m below existing resource
25TK0567: 35m of massive sulphide stringers, 79m below resource
43 meters of vertical mineralization continuity
The Vault Zone sits 79-150 meters below the existing resource, opening an entirely new mineralized horizon.
The Borehole Electromagnetic Advantage
Talon’s systematic BHEM surveying has achieved a near-perfect hit rate when drilling conductor plates. Critically, multiple BHEM anomalies remain untested. The exploration pipeline is robust with numerous high-priority targets awaiting drill testing.
Brian Goldner: “Our methodical approach of focusing on Borehole Electromagnetic anomalies coupled with precision drilling has continued to deliver success within the Vault Zone.”
The Strategic U.S. Angle
Talon recently acquired 100% ownership of the Eagle Mine in Michigan—the only primary nickel mine operating in the United States. The Tamarack Project would become the second domestic primary nickel source.
Government commitment:
$114.8 million DOE grant for Beulah Battery Minerals Processing Facility
$20.6 million DOD grant for exploration
Executive Order (March 20, 2025): “Immediate Measures to Increase American Mineral Production”
Over $135 million in committed federal funding backs this world-class discovery.
The recent closure of the Lundin Mining transaction adds operational expertise and financial strength from a proven global base metals operator.
Resource Potential and Economics
Conservative Scenario (January 30, 2026 Pricing):
3 million tonnes @ 15% NiEq
450,000 tonnes nickel equivalent
At $18,500/tonne Ni: ~$8.3 billion gross in-situ value
At 20% of in-situ value: ~$1.66 billion
Blue Sky Scenario: With 18km of strike length mostly underexplored and mineralization open in all directions, 10-20 million tonnes is plausible.
Key Points:
At 15-28% NiEq, even modest tonnage is highly economic
Copper-to-nickel ratio approaching 1:1 plus precious metals de-risk single-commodity exposure
Depth of 650-800m is standard for high-grade magmatic sulphide deposits
Massive sulphide with ~90% sulphide content should exhibit excellent recoveries

2. Step-Out Drilling (Ongoing)
Three in-house drill rigs actively drilling north and east of discovery. Every successful step-out adds tonnes and extends the footprint.
3. BHEM Follow-Up
Multiple untested electromagnetic anomalies with near-100% historical success rate.
4. Resource Estimate Update
Formal NI 43-101 resource incorporating Vault Zone likely 6-12 months away—a major de-risking milestone.
5. Feasibility Study Progress
Advancing feasibility work supporting the Environmental Impact Statement process.
6. Eagle Mine Performance
Operating cash flow provides financial flexibility that most junior explorers lack.
Quality Assurance
Talon employs industry-leading QA/QC protocols with systematic insertion of certified reference materials, blanks, and duplicates. All samples analyzed by ALS Minerals, a globally recognized independent laboratory. Chain-of-custody procedures are rigorous with tamper-evident security.
Translation: these grades are real. When a company reports 27.28% NiEq over 6.33 meters, those numbers have been verified through multiple checks designed to catch any analytical errors.
Risk Assessment
Operational Risks:
Depth: 650-800m requires underground mining (higher capex/opex but standard for high-grade deposits)
Permitting: Minnesota EIS process will take years; risk of delays
Resource Definition: Early-stage delineation; substantial drilling needed
Capital: Development will require several hundred million dollars
Market Risks:
Nickel Volatility: Currently elevated at $18,500/t but could decline
Copper Risk: Recent prices may be elevated; analysts forecast ~$5.20/lb average 2026
EV Demand: Battery chemistry shifts could pressure nickel long-term
Risk Mitigation:
Government Support: $135M federal funding de-risks early phases
Partnership: Lundin transaction provides expertise and capital access
Grade: 15-28% NiEq provides massive margin cushion
Cash Flow: Eagle Mine operations provide financial flexibility
Investment Thesis: Three Pillars
1. World-Class Asset Quality
Vault Zone results rank among the best Ni-Cu-PGE intercepts globally. Economic across wide range of price scenarios.
2. Strategic Value
Domestic U.S. nickel carries valuation premium in era of supply chain nationalism. $135M government backing validates strategic importance.
3. Exploration Upside
Early-stage delineation with multiple untested targets. 18km strike length mostly underexplored. Discovery growing with each drill campaign.
Conclusion
The junior mining sector is littered with promotional stories. Talon’s Tamarack Vault Zone is different.
These drill results would generate excitement anywhere on the planet. When a company reports intercepts that rival Voisey’s Bay and match Norilsk while backed by $135M in U.S. government funding, the market should pay attention.
The late January 2026 metals volatility—gold crashing $857/oz peak-to-trough, silver down 31% in one day—underscores the value of high-grade deposits that work across wide price scenarios. Tamarack’s economics are robust at $15,000/t nickel and excellent at $18,500/t nickel.
For investors with patience to navigate permitting timelines and conviction to back world-class geology in a strategic jurisdiction, Talon Metals represents a compelling opportunity.
The Vault Zone isn’t just another nickel discovery. It’s a reminder that generational deposits can still be found—if you know where to look.
