TORONTO, Aug. 11, 2026 /PRNewswire/ -- Blue Moon Metals Inc. ("Blue Moon" or the "Company") (TSXV: MOON) $(BMM)$, is pleased to announce the acquisition of a portfolio of 33 tungsten and antimony projects in the western United States (collectively, the "Projects" and each, a "Project"), all of which are proximal to the Company's Springer complex. The Projects are generally located in the most prolific tungsten and antimony producing districts in the United States, with historical production on or adjacent to almost all Projects (see Figure 1). These projects are complementary to the Company's Springer tungsten complex in Nevada and Apex germanium-gallium-copper mine in Utah. The Projects are being acquired on a 100% ownership basis from a private owner on an arms-length basis and consist of BLM and USFS lands (the "Transaction"). Holding costs for the portfolio are approximately US$162,000/yr.

Jason Dunning, Head of U.S. Special Projects for Blue Moon, stated, "This acquisition marks a meaningful step in Blue Moon's strategy to build a leading US-focused critical metals platform. The portfolio represents a compelling collection of tungsten and antimony projects in the United States at a time when domestic sources are increasingly important. Many of these Projects historically produced high-grade antimony and tungsten, including reported tungsten grades of up to 14% WO(3) , during periods of major strategic demand, including WWI, WWII, the Korean War and the Vietnam War. Since that time, the Projects have seen very limited modern work, creating what we believe is a significant opportunity for Blue Moon to apply a disciplined, modern approach across a historically important package of assets. While tungsten was the focus of the historical work, it should be noted that tungsten mineralization may also provide important indications for copper and gold exploration potential. We intend to methodically advance several of these Projects, with a focus on leveraging the Company's Springer complex in Nevada for potential processing, while seeking to unlock value from the broader portfolio through future monetization opportunities."

TRANSACTION

Consideration for the Projects consists of the following:

   -- 2.8 million common shares of the Company, subject to a 4-month holding

          -- The Development Payments will be paid either in cash or split 50% 
             cash and 50% in Blue Moon common shares, at Blue Moon's election; 
             and 
 
          -- Each Development Payment will be capped at a maximum aggregate 
             payment of US$8.5 million per Project. 
 
   -- A monetization incentive based on consideration received by Blue Moon 
      from the disposal of any Project: 
 
          -- A payment of 10% of the consideration received by Blue Moon, 
             payable in cash or shares at Blue Moon's discretion; and 
 
          -- An inferred resource development milestone payment on tungsten 
             projects advanced by the then owner of each Project within 15 
             years of the Closing Date, totaling US$1.50/MTU WO3. 

KEY PROJECTS IN PORTFOLIO

Blue Moon considers four of the Projects to be high priority for direct shipping high-grade tungsten ores to its Springer Complex (the "Key Projects"):

Oregon Mine, Colorado

The Boulder County Tungsten District forms a south-west to north-east belt about 9.7 km long (about 6.0 miles) and 1.6 to 4.8 km wide (about 1.0 to 3.0 miles) on the east flank of the Front Range, in Precambrian-aged metamorphic and intrusive terrain near the Colorado mineral belt. The dominant rocks are Precambrian Boulder Creek granite and younger Silver Plume granite that are cut by early Tertiary biotite latite dikes and intrusions, locally overlain by Quaternary deposits. The tungsten-bearing veins are Tertiary in age, interpreted by Lovering (USGS Professional Paper 245, 1953) as related to the biotite latite intrusion.

Mineralization is ferberite (with secondary scheelite) in chalcedonic quartz fissure veins (the Oregon, Quaker City and Hildegarde veins) in the Boulder Creek granite. Historically, there is documented production in the USGS Professional Paper 245 of approximately 5,000 short tons with an average grade of about 14.51% WO(3) between 1907 and 1929, noting that it is from hand-sorted vein ore that a qualified person has not verified and that must not be relied upon for the mineralization associated with this important target. The veins are narrow and typically high-grade in the district. No modern exploration, no drilling under a documented program, no QA/QC-controlled sampling, and no metallurgical test work has been carried out.

Wildhorse Canyon, Idaho

Tungsten was discovered at Wildhorse Canyon in August 1953 and mined by Cordero Mining Co. between 1954 and 1958. Recorded historical production between 1954 and 1957 was approximately 12,000 tons of ore mined from Steep Climb, Hard to Find and Beaver, yielding 7,461 short ton units (149,220 lb) of WO(3) (Mitchell, 1999) or a grade of 0.62% WO(3) . Historical exploration drilling totaled eleven holes (4,724 feet) on Steep Climb (1982) and two holes (205 feet) on Hard to Find (1985); collars and assays are not in the public record and are unverified.

The deposits are reduced / calcic scheelite skarns (tactite) developed where leucogranodiorite to "alaskite" dikes intruded and metasomatically replaced impure, micaceous marble bands enclosed in biotite gneiss, migmatite and quartzite. Mineralization is structurally controlled along the crest of a north-northwest trending (N15 to N20 W) asymmetric anticline and is restricted to tactite in impure marble adjacent to the dikes; pure marble is barren. Ore minerals are scheelite with molybdenite in epidote and chlorite-garnet tactite; trace beryllium is reported. Bodies are tabular lenses and pods, generally 5 feet or less thick, over a mineralized horizon traced and projected for about 5.7 km (about 3.5 miles).

Williams, Arizona

The Williams Project is hosted in a light-colored, coarse-grained granite, locally banded or gneissoid, and it is cut by irregular aplite and pegmatite dykes. Tungsten mineralization occurs as huebnerite (MnWO(4) ), the manganese-rich end of the wolframite series, as bladed crystals (to about 7.5 cm) enclosed in quartz and along mica seams within gently north-dipping quartz veins associated with an aplite dyke. Two vein sets are documented in the district: a gently north-dipping set (about 18 to 30 degrees north) striking approximately east-west (N70 to N80 W underground), which hosts the productive Williams vein; and a steeply north-dipping set of broadly parallel strike, which appears less productive. The principal vein was explored over approximately 195 metres (about 640 feet) of strike and about 97.5 metres (about 320 feet) down-dip.

Documented exploration and development on the Project was carried out by historical operators between 1902 and 1955 and consisted of hand and conventional underground development: three upper adit levels (the 200-, 260- and 280-feet levels), a lower haulage adit (the "0" level), an inclined winze and connecting raises, totaling about 1,200 m (about 4,000 feet) of underground workings on as many as seven levels, together with numerous surface cuts and pits. A total of approximately 88,000 t of ore was historically mined over the mine life at a grade of 0.75% WO(3) . No systematic modern exploration (geochemistry, geophysics, modern drilling) has been documented since the 1961 United States Bureau of Mines (USBM) circular.

Hub Mines, Nevada

The Hub Mines deposit is a tungsten-bearing quartz-vein system hosted in a Jurassic quartz monzonite intrusion within the Basin and Range Province. Mineralization occurs in at least six narrow quartz veins arranged in a north-east-trending, en-echelon array, dipping approximately 55 to 75 degrees to the west; the principal vein, the Hub Vein, has a documented strike length of more than 400 metres (about 1,300 feet). Vein widths range from a few centimeters to about 1.5 metres (a few inches to 5 feet). The dominant ore mineral is huebnerite (MnWO(4) ), with subordinate wolframite and scheelite, and minor to trace lead, silver, gold, copper, fluorite, and locally antimony. The recorded average mill-feed grade for historical production was approximately 1.4% WO(3) , and one shipment of hand-sorted ore is recorded at about 20% WO(3) that a QP qualified person has not verified and that must not be relied upon for the mineralization associated with this important target. The 1983 USBM survey records that no workings have explored the depth of the mineralized veins, so the veins are interpreted to remain open at depth.
