Resolution: ‘Exceptional’ tungsten grades in historical stockpiles at newly-acquired Johnson Creek mill

Resolution Minerals Ltd (ASX:RML) has announced promising results from its recently acquired Johnson Creek tungsten and antimony mill, revealing high-grade tungsten from historical stockpiles. The company reported a grade of 1.85% WO₃ from early sampling, which aligns with historical production data from the Golden Gate Tungsten Mine. This discovery is particularly noteworthy as it significantly exceeds the typical global underground mining grades of 0.15% to 0.20% WO₃, as reported by the U.S. Geological Survey. The fieldwork, completed in late calendar year 2025, involved mapping and collecting representative samples from stockpiles that have remained untouched since the 1980s. Among these was a 93.6-kilogram mini-bulk composite sample, which underwent multi-element geochemical analysis and mineralogical assessment by Independent Metallurgical Operations.

The timing of this announcement is critical, as tungsten prices have surged due to recent global supply constraints, reaching approximately US$2,200 per metric ton. This price increase is compounded by U.S. government initiatives aimed at rebuilding critical mineral supply chains, including a substantial US$12 billion program to reduce reliance on offshore sources. Resolution's executive director, Aharon Zaetz, emphasized the significance of confirming such high-grade tungsten from the Golden Gate stockpile, suggesting that it presents a compelling opportunity to fast-track these stockpiles for potential near-term offtake options, should further work yield positive results.

From a financial perspective, Resolution Minerals has a market capitalization of AUD 106.9 million. The company is now focused on a detailed sub-surface sampling program, volumetric surveys to quantify tonnage, and specific gravity analysis. These steps are essential for upgrading the historical and foreign estimates to JORC-2012 compliance, which is a prerequisite for potential future offtake agreements. However, the company must also consider its funding position. While the announcement does not disclose specific cash balances or recent capital raises, the need for additional funding to support the upcoming work programs could pose a dilution risk to existing shareholders.

In terms of valuation, it is essential to compare Resolution Minerals with its peers in the tungsten sector. Given its market capitalization, the company is positioned within the micro-cap tier. Direct peers include companies such as Tungsten Mining NL (ASX:TGN) and King Island Scheelite Ltd (ASX:KIS), both of which are also engaged in tungsten exploration and development. Tungsten Mining NL has a market capitalization of approximately AUD 80 million, while King Island Scheelite Ltd is valued at around AUD 150 million. This comparison highlights that Resolution Minerals is competitively positioned within the micro-cap tier, with its high-grade findings potentially enhancing its valuation relative to peers.

The execution track record of Resolution Minerals will be crucial as it moves forward. The company has historically focused on acquiring and developing mineral assets, but it remains to be seen whether it can consistently meet its timelines and deliver on its strategic objectives. The announcement of high-grade tungsten is a positive step, but investors will be watching closely for the results of the upcoming sampling and surveys. Specific risks include the potential for funding gaps if the company cannot secure sufficient capital for its planned work programs, as well as technical uncertainties related to the processing of the tungsten and antimony ores.

Looking ahead, the next measurable catalyst for Resolution Minerals will be the results from the detailed sub-surface sampling program and volumetric survey, which are expected to provide clarity on the tonnage and quality of the resource. These results are anticipated in the near term, although specific timing has not been disclosed. Overall, the announcement regarding the exceptional tungsten grades at the Johnson Creek mill is classified as significant, given its potential to materially impact the company's valuation and operational strategy. The high-grade findings, coupled with favorable market conditions for tungsten, position Resolution Minerals favorably within the sector, although the company must navigate funding and execution risks as it advances its projects.
