- Historical hole NM-13 returned 7.00 metres grading 1.28% WO₃ and 0.01% molybdenum.
- Blue Moon has relogged 11,670 metres, about 64% of the 18,000 metres of historical core available at Springer.
- BLM approval covers 13 drill pads on public land and supports the company’s planned 67,000-metre exploration program.
Historical core is delivering new high-grade tungsten data
Blue Moon Metals’ September 22 update adds fresh assay information to the Springer Tungsten Project in Nevada from an 18,000-metre historical-core relogging and re-assay campaign. The strongest highlighted surface interval came from hole NM-13, which returned 7.00 metres grading 1.28% tungsten trioxide and 0.01% molybdenum from 160 metres.
Another surface hole, NM-44, returned 24.25 metres grading 0.22% WO₃ and 0.03% molybdenum, including 9.55 metres at 0.53% WO₃ and 0.12% molybdenum. Underground hole SU-27 returned 8.24 metres at 0.64% WO₃ and 0.01% molybdenum, including 3.09 metres at 1.19% WO₃.
The program is giving Blue Moon modern analytical information from core originally drilled during earlier operating periods, including sections that were not comprehensively assayed under current protocols.

Nearly two-thirds of the available historical core has now been relogged
Blue Moon says 11,670 metres of the roughly 18,000 metres of available historical diamond core has now been relogged, representing about 64% of the archive. Final assay results have been received for 18% of the historical meterage.
The current program expands sampling beyond the selectively tested high-grade intervals used by earlier operators. Blue Moon is adding buffers around higher-grade mineralization and testing lower-grade and previously untested material to build a more complete geological dataset.
That work is intended to strengthen the geological model before new drilling begins, while also providing modern multi-element assays for tungsten and associated metals.
BLM approval clears 13 new drill pads on public land
The U.S. Bureau of Land Management fully approved Blue Moon’s exploration notice on September 10 after the associated reclamation bond was posted. The approval allows five acres of disturbance and includes 13 diamond-drill pads on public land around the Springer project area.
The notice also permits mechanized auger sampling of existing tailings material. Blue Moon says the approval supports its broader 67,000-metre exploration drilling campaign announced earlier in the year.
With the regulatory step completed, the company can pair its reinterpretation of historical core with new drilling designed to test the mineralized system using the updated geological model.

Stockpile sampling adds a near-term operating workstream
Blue Moon has also completed a program covering 28 existing stockpiles at Springer, collecting 499 grab samples plus 79 quality-control samples. A LiDAR survey was completed to estimate the volume of each stockpile and provide a basis for tonnage calculations.
The company says the stockpiled material is expected to form initial mill feed in 2027, tying the sampling program to Springer’s existing 1,200-tonne-per-day flotation plant and processing infrastructure.
The combination of modern core assays, approved drill pads and stockpile characterization gives Blue Moon several parallel workstreams at Springer: validate historical geology, expand the drill dataset and prepare existing surface material for potential processing.
