Resolution Minerals (ASX:RML) says it’s on the fast track to JORC-code compliance after uncovering “exceptional” high-grade tungsten from early sampling at its recently acquired Johnson Creek tungsten and antimony mill.

The results, derived from historical stockpiles untouched since the 1980s, showed a 1.85% WO₃ grade that aligns with older, historical production data.
The fieldwork, completed in late CY25, involved mapping and collecting representative samples from stockpiles from the historical Golden Gate Tungsten Mine. Among the pile was a 93.6-kilogram mini-bulk composite sample made up of six individual samples that underwent multi-element geochemical analysis and mineralogical assessment by Independent Metallurgical Operations.
Key technical findings included grades at 1.85% WO₃ and 0.11g/t gold. Scheelite (CaWO4) was identified as the predominant tungsten ore mineral, and analysis showed minimal levels of deleterious elements, with arsenic at 97ppm, and both molybdenum and phosphorus falling below detection levels.
The overall haul “significantly exceeds” the typical global underground mining grades of 0.15% to 0.20% WO₃ reported by the U.S. Geological Survey.
“Confirming a high-grade [like this] from the Golden Gate stockpile is a significant milestone,” executive director Aharon Zaetz declared.
The Resolution chief explained that the standout combination of strong grade, scheelite-dominant mineralisation, and lower impurity levels highlights the potential for a simple and low-cost processing pathway.
“Furthermore, given Golden Gate has previously been mined for tungsten, and has supplied the U.S. Government with critical metals for several war efforts during the 20th Century, this presents a compelling opportunity to fast-track the stockpiles should further planned work prove positive,” Mr Zaetz said.
These finds come right when tungsten is surging price-wise; recent global supply constraints have left the metal at up to ~US$2,200 per metric ton.
Resolution is also rubbing its hands at the timing with recent U.S. government policy initiatives, most importantly, including a US$12B program to rebuild critical mineral supply chains and reduce offshore dependency.
Next steps for Resolution include a detailed sub-surface sampling program, a volumetric survey to quantify tonnage, and specific gravity analysis. These works will help the company upgrade the historical and foreign estimates to JORC-2012 compliance on the road to possible near-term offtake options.
RML shares are +6.2% up to lunchtime Thursday.
