Viking Mines Delivers Exceptional Tungsten Results from Nevada Project
Viking Mines Ltd (ASX: VKA) has reported impressive tungsten oxide (WO3) assay results from its Linka Project in Nevada, USA, with the standout 58kg metallurgical sample returning 1.3% WO3. The Viking Mines Linka Project results validate the high-grade potential of this strategic US tungsten asset during a period of unprecedented market strength.
The company collected four metallurgical samples totalling 295kg from various locations across the Linka Project, with results ranging from 0.8% to 1.3% WO3 and achieving a weighted average grade of 1.0% WO3 across all samples. These Viking Mines Linka Project results confirm the exceptional quality of scheelite mineralisation at Linka, one of six US-based tungsten projects Viking is currently acquiring.
The timing could not be better, with global scheelite concentrate prices at all-time highs of US$937 per metric tonne unit (mtu) for 25%-30% grade material. Furthermore, this makes high-grade tungsten projects increasingly valuable in today's market.

Outstanding Metallurgical Sample Results Validate Historical Data
The four metallurgical samples collected during Viking's due diligence site visit have delivered compelling results that align with historical production data from the 1950s:
| Sample Location | Weight (kg) | WO3 Grade (%) |
|---|---|---|
| Linka Open Pit | 58.3 | 1.3 |
| Conquest Open Pit | 85.7 | 1.0 |
| Hillside Shaft | 53.8 | 0.9 |
| Linka Stockpile | 97.4 | 0.8 |
| Total/Average | 295.2 | 1.0 |
The 1.3% WO3 result from the Linka Open Pit is particularly significant, representing a head-grade that far exceeds many operating tungsten mines globally. In contrast, grades as low as 0.2% WO3 are considered economic elsewhere.
"To attain a head-grade of 1.3% WO3 is a significant outcome and provides strong encouragement for the Linka Project. This is especially relevant when mines are operating globally with grades as low as 0.2% WO3," said Julian Woodcock, Managing Director.
The samples were processed at Base Met Labs in Tucson, Arizona, using industry-standard lithium metaborate/lithium tetraborate fusion followed by ICP OES/MS analysis. Moreover, this technique is considered to provide total tungsten recovery measurements.
Understanding Scheelite and Tungsten Market Dynamics
What is Scheelite?
Scheelite (CaWO4) is the primary mineral source of tungsten, a calcium tungstate mineral that can be easily identified under ultraviolet light. When exposed to UV light, it fluoresces bright white-blue, making identification straightforward for geologists.
Tungsten is a critical metal used in cutting tools, aerospace applications, military hardware, and emerging clean energy technologies. The metal's exceptional hardness and high melting point make it indispensable for industrial applications.
Why These Grades Matter
The Viking Mines Linka Project results demonstrate grades that significantly exceed typical industry benchmarks. Consider the following comparisons:
- Current global tungsten concentrate prices: US$937/mtu
- Many operating mines work grades of 0.2-0.4% WO3
- Viking's 1.0% average grade represents 2.5-5x typical operating grades
- The 1.3% peak result positions Linka among high-grade global tungsten deposits
The tungsten market has experienced significant price appreciation, with scheelite concentrates reaching all-time highs. This increase stems from supply constraints and growing industrial demand across multiple sectors.
Strategic US Location Provides Jurisdictional Advantage
The Linka Project's location in Nevada provides several competitive advantages for Viking Mines. Additionally, the state offers established mining infrastructure and regulatory frameworks.
Tier 1 Jurisdiction Benefits
The project benefits from multiple jurisdictional advantages:
- Established mining regulatory framework
- Reliable infrastructure and power supply
- Skilled mining workforce availability
- Political stability and mining-friendly policies
- Proximity to US defence and industrial customers
Historical Production Validation
The Linka Mine has a proven production history that validates the Viking Mines Linka Project results. Historical production records show:
- 2,420 tons averaging 0.69% WO3 (1943-44)
- 4,000 tons averaging 0.98% WO3 (1951-56)
- 60,000 tons averaging 0.40% WO3 (1955-56)
This historical production totalling approximately 25,670 units of WO3 demonstrates the deposit's commercial viability. Furthermore, it provides a foundation for future development planning based on proven geological understanding.
Process Development and Metallurgical Testing
Viking has commenced sighter metallurgical testwork on the high-grade samples to establish a process flowsheet for scheelite concentrate production. The company is working with Base Met Labs to develop an optimal processing route.
The metallurgical approach focuses on conventional gravity concentration methods, which are typically well-suited to scheelite mineralisation. For instance, this process development work will inform future plant design considerations and operating cost estimates.
Testwork Objectives
The comprehensive testwork programme aims to achieve several key objectives:
- Determine optimal crushing and grinding parameters
- Establish gravity separation efficiency
- Define concentrate grade and recovery targets
- Assess potential for secondary processing stages
Development Pipeline Through 2026
Viking has outlined a systematic approach to advancing the Linka Project through the remainder of 2026. However, this timeline depends on regulatory approvals and market conditions.
Immediate Next Steps
The company has prioritised several immediate activities:
- Complete metallurgical testwork flowsheet development
- Conduct high-resolution aerial surveys
- Execute gravity and magnetics geophysical surveys
- Compile and evaluate historical data archives
Medium-Term Milestones
Looking ahead, Viking has established several critical milestones:
- Process assays from additional due diligence sampling
- Complete drill hole planning and permitting applications
- File Notice of Intent with Federal Agencies for drilling permits
- Commence resource definition drilling programmes
The company is simultaneously advancing assessment work on the five additional tungsten projects being acquired. This creates a portfolio approach to US tungsten development with diversified risk profiles.
Investment Thesis: Positioning for the Tungsten Supercycle
Viking Mines is strategically positioning itself in the tungsten sector at an opportune time. Several factors are aligning to support the investment case across multiple fronts.
Market Fundamentals
Current market conditions favour tungsten developers:
- Record tungsten prices driven by supply-demand imbalance
- Growing demand from clean energy and defence sectors
- Limited new supply sources globally
- US strategic mineral designation for tungsten
Project Quality Indicators
The Viking Mines Linka Project results demonstrate several competitive advantages that distinguish it from other tungsten assets:
- High-grade mineralisation validated by recent assays
- Proven historical production from multiple mine sites
- Tier 1 Nevada jurisdiction with established mining infrastructure
- Six-project portfolio providing diversification and scale potential
Financial Considerations
The acquisition structure allows Viking to secure these assets through staged payments totalling US$2.88M over seven years. Additionally, the company has the option to buy down a portion of the 2% NSR royalty for US$2M, providing operational flexibility as projects advance.
Critical Minerals and Strategic Importance
Tungsten's classification as a critical mineral by the US Government adds strategic importance to Viking's Nevada-based projects. The metal's essential role in defence applications creates strong fundamental demand drivers.
Strategic Applications
Tungsten serves multiple strategic applications across various industries:
- Military and aerospace components
- Industrial cutting and drilling tools
- High-temperature applications
- Clean energy technology components
The US seeks to reduce dependence on foreign tungsten sources, potentially creating preferential treatment for domestic production. Consequently, this policy environment could benefit projects like Linka that advance towards production.
