TORONTO , Sept. 22, 2026 /PRNewswire/ -- Blue Moon Metals Inc. (" Blue Moon " or the " Company ") (TSXV: MOON) (NASDAQ: BMM), is pleased to provide new assay results from its ongoing 18,000 m relogging campaign at the Springer Tungsten Project in Pershing County, Nevada (" Springer ") as well as other updates to the exploration program. Springer is a facility with a 1,200 tpd flotation plant, oversized ammonium paratungstate (" APT ") circuit, along with ancillary facilities, utilities and a large unutilized conventional tailings dam. This program is validating extensive historical datasets, including assaying of untested mineralized core, enhancing the geological model and unlocking the broader scale potential of the mineralized system.

HIGHLIGHTS

1) HISTORICAL CORE RE-ASSAY PROGRAM The Company has undertaken a thorough re-examination and re-assay campaign of previously drilled core located on the property. To date, approximately 64% of the 18,000 meters of historical core has been relogged, including 18% of the historical meterage received as final assay results. Some of the best results include:

Surface drillhole NM-13 confirmed a 7.00 m interval grading 1.28% WO₃ and 0.01% Mo from 160 m;

Surface drillhole NM-44 confirmed a 24.25 m (13.72 m true width) interval grading 0.22% WO₃ and 0.03% Mo from 249 m, including 9.55 m (5.40 m true width) grading 0.53% WO₃ and 0.12% Mo; and

Underground drillhole SU-27 confirmed an 8.24 m (6.34 m true width) interval grading 0.64% WO₃ and 0.01% Mo from 59 m, including 3.09 m grading 1.19% WO₃ and 0.02% Mo.

2) STOCKPILE SAMPLING UPDATE The Company has completed a field program to sample and assay previously defined stockpiles on the property, resulting in 499 unique samples. These samples will be used to ascertain the grade and determine viability for processing the stockpiles through the Springer mill. This sampling is being combined with a LiDAR survey completed in August to estimate the tonnage of material available.

3) BLM APPROVAL OF EXPLORATION NOTICE The Bureau of Land Management has approved the submitted Exploration Notice to perform selected works on public land. Five acres of disturbance is included in the notice, including drilling and drill roads in the southwest quadrant of the near mine area, access to private land in the northwest quadrant, and auger tailings sampling to the southeast of the main gate.

Theodore Veligrakis, VP Exploration, stated, ''The results from the historical core re-assay program are very encouraging and continue to validate the quality and scale of the mineralized system at Springer. In particular, the higher-grade intervals demonstrate the potential for meaningful grade continuity within the broader tungsten system. Combined with the ongoing geological relogging, stockpile sampling and our expanding exploration program, we are building a much stronger understanding of Springer's overall resource potential and how we can best advance and expand it.''
