Key Terms

ammonium paratungstate, lidar, xrf analysis, qa/qc

4 terms

ammonium paratungstate technical

"oversized ammonium paratungstate ("APT") circuit"

Ammonium paratungstate (APT) is a dense, white powder that serves as the concentrated chemical feedstock used to produce tungsten metal and tungsten-based products. Think of it as a syrup concentrate that manufacturers refine into final goods like heavy-duty metal parts, lightbulb filaments, and specialty coatings. Investors watch APT because its production volumes, quality and price act as an early signal of tungsten supply, manufacturing costs and margin pressure across mining, industrial and defense-related companies.

lidar technical

"a LiDAR survey completed in August"

Lidar, which stands for Light Detection and Ranging, is a technology that uses laser beams to create detailed, three-dimensional maps of the environment. It works like a sophisticated eye that measures distances by bouncing light off objects, helping machines see and understand their surroundings. For investors, lidar is important because it enables advancements in autonomous vehicles, robotics, and mapping, which can drive innovation and growth in related industries.

xrf analysis technical

"include XRF analysis for WO₃"

XRF analysis is a laboratory technique that identifies the elemental makeup of a sample by shining X‑rays on it and measuring the characteristic secondary rays each element emits — like using a fingerprint scanner to tell which metals or elements are present. Investors care because XRF gives quick, non‑destructive confirmation of raw material quality, mineral grades, product composition or contamination, which can affect production costs, regulatory compliance and the value of assets.

qa/qc technical

"Comprehensive QA/QC protocols have been implemented"

QA/QC stands for Quality Assurance and Quality Control, processes used to ensure products or services meet certain standards. Think of it as a way to check that a product is safe and works properly before reaching consumers, similar to how a chef tastes food before serving it. For investors, strong QA/QC practices indicate a company's commitment to delivering reliable, high-quality offerings, reducing risks and building trust.

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.''

1) HISTORICAL DRILLING ASSAY HIGHLIGHTS

The Company has access to approximately 18,000 meters of historical diamond drill core for re-logging. The archive includes SU underground drillholes and NM surface drillholes completed by General Electric in the late 1970s and early 1980s. It also includes select holes from the 2007 campaign by Golden Predator before RC drilling was introduced. To date, 11,670 meters of historical core have been re-logged as part of the Company's ongoing validation and geological reinterpretation program. Historical sampling covered only ~5% of the available core, was limited to tungsten assays, and had no documented QA/QC procedures, despite pXRF and visual confirmation of other economic mineralization, including but not limited to copper, molybdenum, and silver.

The current sampling program shown in Figure 1 includes quarter-core sampling of previously assayed intervals as well as substantial volumes of previously untested mineralized rock. Historical mining and tungsten pricing led to selective "high-grading" of the drill core, focused mainly on the richest portions of the scheelite-bearing units, instead of a true statistical representation of the geological host of the mineralization. The expanded assay program now includes buffers around high-grade mineralization, lower-grade material, and mineralization outside the main skarn lenses, including the Granodiorite Springer Stock, a significant secondary target not previously evaluated. The historical drillhole NM-49 reaches a true depth of 880 m below surface- twice the depth of other drilling on the property.  It was originally drilled as an investigatory hole before sinking the Sutton 3 Shaft and returned favorable grades in the granodiorite. This intrusive hosts extensive quartz veining, variable molybdenite, chalcopyrite, and tungsten mineralization, along with evidence of elevated bismuth-bearing minerals. This deep hole offers a glimpse into the potential of a larger driving system at depth, warranting further follow-up and interpretation.

The following 2 tables outline the initial results of the re-assaying program and Figure 2 is a section of re-assayed results at Sutton 2.

2) STOCKPILE SAMPLING

The grab sampling program of pre-existing stockpiles was completed on September 6, 2026 (Figure 3). The purpose of this sampling is to test for grade distribution and material characteristics for all previously mined material that remains stockpiled on surface, to assess the viability of processing this previously mined material through the Springer mill. Samples were taken at approximately ten-meter intervals around the base of defined stockpiles, containing representative lithologies of the material. In total, twenty-eight stockpiles were sampled, with 499 grab samples and 79 Quality Control samples shipped to ALS Labs in Reno, NV. Assays for this resampling program remain pending.

In August, a LiDAR survey was also completed to generate accurate volume estimates for each stockpile, providing the basis for estimating tonnage. This stockpiled material is expected to form the initial mill feed in 2027.

3) BLM EXPLORATION NOTICE APPROVAL

Blue Moon's application to the United States Bureau of Land Management (BLM Exploration Notice NVNV106841534) in support of exploration activities on public lands was conditionally accepted on August 26, 2026, and fully approved on September 10, 2026, following payment of the associated reclamation bond. The approval of this application grants Blue Moon permission to conduct new exploration diamond drilling on 13 pads on public lands in support of the 67,000 m drilling campaign (Figure 4). The application also provided Blue Moon approval to conduct mechanized auger sampling of existing tailings material (see Blue Moon news release, July 7, 2026).

PRICING AND ISSUANCE OF THE ELMET GROUP CO. WARRANTS TO BLUE MOON

On September 21, 2026, as required by the binding letter agreement entered into between The Elmet Group Co. ("Elmet") and Blue Moon announced on September 14, 2026 regarding a series of strategic transactions intended to unlock the value of Blue Moon's Springer Tungsten Complex, Elmet issued to Blue Moon warrants to purchase 1,166,970 shares of Elmet common stock at an exercise price of US$21.423 per share.

SAMPLING AND QA/QC

The Springer Mine hosts historical drill core from multiple previous owners of the property, in core diameters of BQ, NQ, and HQ sizes.

The ongoing re-logging and sampling program has increased sampling coverage to approximately 44% of the available core. Final assay results from ALS Labs in Reno, Nevada, have been received for 18% of the historical core. Samples are being analyzed by ALS Geochemistry using analytical packages that include XRF analysis for WO₃, a 48-element multi-element suite, and selective fire assay for gold. Comprehensive QA/QC protocols have been implemented in accordance with CIM Best Practice Guidelines, with QA/QC samples representing approximately 12.5% of all assays, or a 1:8 ratio. These protocols support a robust dataset for future exploration targeting and resource evaluation.

The current sampling program includes quartering of previously assayed material and a large volume of previously untested, but mineralized rock. Due to the historical mining methods and tungsten prices, the drill core was "high-graded", with focus only on skarn hosted scheelite rich zones. New assaying includes buffers to high grade mineralization, lower grade material, ore hosted outside the main skarn lenses including a major secondary source not considered previously – the Granodiorite Springer Stock. This intrusive hosts significant quartz veining, variable molybdenite, chalcopyrite, and tungsten mineralization and evidence of elevated bismuth bearing minerals.
