Resolution Minerals Unlocks High-Grade Tungsten from Historical Stockpiles
Resolution Minerals (ASX: RML, OTCQB: RLMLF) has delivered exceptional results from its preliminary sampling of historical tungsten stockpiles at the recently acquired Johnson Creek Mill. The 1.85% WO₃ grade from a 93.6kg composite sample confirms the high-grade nature of material sourced from the Golden Gate Tungsten Mine, positioning the company to fast-track potential tungsten production in a critical minerals market experiencing unprecedented price growth.
The sampling programme revealed low impurity levels including arsenic at just 97 ppm, with molybdenum and phosphorus below detection limits. Independent mineralogy studies identified scheelite as the predominant tungsten mineral with quartz comprising over 90% of gangue material—a combination that typically supports simpler, lower-cost processing pathways.
"Confirming a high-grade 1.85% WO₃ result from the Golden Gate stockpile is a significant milestone for Resolution Minerals. The combination of strong grade, scheelite-dominant mineralisation and low impurity levels highlights the potential for a simple, low-cost processing pathway," commented Executive Director Aharon Zaetz.

Stockpile Sampling Delivers Consistent High-Grade Results
The comprehensive mapping and sampling programme involved six samples collected from different locations across two adjacent stockpiles using both random selection and blue-light selective methods. All samples displayed characteristic granodiorite host rock with visible scheelite mineralisation occurring as veins and disseminations.
The comprehensive Resolution Minerals tungsten stockpile assessment demonstrates remarkable consistency across multiple sampling locations. Furthermore, the results validate the high-grade potential that has attracted significant market attention.
Key Sampling Results
| Parameter | Result | Significance |
|---|---|---|
| WO₃ Grade | 1.85% | Consistent with historical production grades |
| Gold Content | 0.11 g/t | Additional value potential |
| Arsenic | 97 ppm | Low impurity levels |
| Molybdenum | Below detection | Simplified processing requirements |
| Phosphorus | Below detection | High-grade concentrate capability |
| Sample Weight | 93.6 kg | Representative composite from 6 locations |
The 1.85% WO₃ result aligns closely with historical production data. In addition to the current results, historical records show:
- 1,814 tons averaged 1.5% WO₃ (1950s)
- 227 tons averaged 2.03% WO₃ (1973)
- 456.6 tons averaged 1.8% WO₃ (1977)
Understanding Tungsten: A Critical Mineral Primer
Tungsten trioxide (WO₃) represents the industry standard for measuring tungsten content in ore. This hard, dense metal possesses unique properties that make it essential for industrial applications including high-temperature alloys, cutting tools, and defence applications.
The Resolution Minerals tungsten stockpile grade of 1.85% WO₃ is exceptionally high compared to global benchmarks. However, most underground tungsten mines typically yield 0.15-0.20% WO₃ globally.
Moreover, Resolution's stockpiles contain 1.85% WO₃, which represents 9-12 times the typical global grade. This processing advantage means higher grades reduce processing costs per unit of tungsten produced.
Scheelite (CaWO₄) is the calcium tungstate mineral containing 80.52% WO₃ by molecular weight. Its presence as the dominant tungsten mineral, combined with high quartz content, suggests favourable metallurgical characteristics including easier grinding and tungsten liberation at coarser sizes.
Strategic Positioning in Critical Minerals Market
Resolution Minerals has positioned itself advantageously in the tungsten market during a period of significant price appreciation and supply chain focus. Tungsten prices have surged from under US$400 to US$2,200 per metric ton due to ongoing global conflicts and tight supply conditions.
Market Context
The current market environment presents exceptional opportunities for tungsten producers. For instance, the US government is actively working to rebuild domestic tungsten supply chains as part of a US$12 billion policy initiative to stockpile critical minerals.
Furthermore, there is growing focus on reducing offshore supply dependency. Additionally, the Golden Gate mine has historical significance, having previously supplied the US Government with critical metals during multiple 20th century war efforts.
The estimated 2,000 tonnes of stockpiled material represents immediate production potential without the time and capital requirements typically associated with new mine development. The Resolution Minerals tungsten stockpile has remained undisturbed since the 1980s, as evidenced by vegetation regrowth.
Fast-Track Development Strategy
Resolution's acquisition of the Johnson Creek Mill provides both the stockpiled ore and processing infrastructure to potentially accelerate tungsten production. The 15-acre facility includes processing mill infrastructure, direct access to historical tungsten stockpiles, and proximity to the Golden Gate mine site.
Immediate Next Steps
The company has outlined a comprehensive development pathway. In addition to current activities, Resolution plans to execute the following initiatives:
-
Detailed Stockpile Sampling Programme
- Sub-surface sampling to assess grade continuity
- Volumetric survey for precise tonnage calculations
- Specific gravity analysis for tonnage conversions
-
JORC-Code Upgrade Process
- Systematic sampling to achieve compliance standards
- Resource estimation and classification
- Metallurgical test work optimisation
-
Processing Pathway Development
- Leverage existing mill infrastructure
- Optimise flowsheet for scheelite concentration
- Direct offtake opportunities during development
What Makes This Tungsten Project Special?
The metallurgical characteristics of the Resolution Minerals tungsten stockpile suggest several processing advantages. Moreover, these characteristics typically support the production of high-grade tungsten concentrates meeting ammonium para-tungstate (APT) refinery specifications.
The key metallurgical findings include scheelite-dominant primary tungsten mineral that is well-understood metallurgically. Furthermore, high quartz content supports easier grinding and mineral liberation. Additionally, low impurities mean arsenic, molybdenum, and phosphorus are at minimal levels.
The absence of significant deleterious elements simplifies concentrate specifications and potentially commands premium pricing. However, further metallurgical testing will confirm optimal processing parameters for the Resolution Minerals tungsten stockpile.
Investment Thesis: Critical Minerals with Processing Advantage
Resolution Minerals offers investors exposure to the critical minerals theme through a unique combination of high-grade stockpiled ore, existing processing infrastructure, and strategic US location. The tungsten opportunity complements the company's broader portfolio focused on antimony, tungsten, and gold production capabilities.
Key Investment Highlights
| Advantage | Details |
|---|---|
| High-Grade Material | 1.85% WO₃ vs. 0.15-0.20% global average |
| Low Impurities | Simplified processing and higher concentrate grades |
| Existing Infrastructure | Processing mill reduces capital requirements |
| Strategic Location | US-based asset aligned with supply chain policies |
| Fast-Track Potential | Stockpiled ore eliminates mining development timeline |
The scheelite-dominant mineralogy and high quartz content suggest favourable metallurgical characteristics. In addition, low arsenic, molybdenum, and phosphorus levels support production of high-grade concentrates meeting ammonium para-tungstate (APT) refinery specifications.
Market Timing and Policy Alignment
The successful stockpile sampling represents significant validation of Resolution's strategy during optimal market conditions. With tungsten prices at US$2,200 per metric ton compared to historical levels below US$400, the timing for advancing the Golden Gate stockpiles aligns with both market conditions and US critical minerals policy initiatives.
The combination of high-grade material, existing infrastructure, and strategic location positions Resolution to potentially capture significant value from the tungsten opportunity. Furthermore, the company continues developing broader critical minerals capabilities across its portfolio.
