Blue Moon Metals Inc.  (TSX-V: MOON) (NASDAQ: BMM), is pleased to announce new drilling results from its ongoing surface infill program at the Company’s Nussir Project, currently under construction in Finnmark, Norway. The infill program, initiated in March, aims to increase confidence in the Project’s reserves, and particularly the proven category. The program is ongoing, having originally started closest to initial planned mining locations, and progressing westwards. Also included in this release are further results from the 1.2 km deep exploration campaign.

INFILL DRILLING ASSAY HIGHLIGHTS

This news release includes assays from 12 surface infill holes. The HQ diamond drill holes total 2,628.6 m with starting depths ranging from 146.8 m to 459.8 m.

The 12 holes listed below test a strike length of over 700 m of the current Indicated Resource nearest the initial planned production areas, confirming mineralization continuity in areas with previously sparse intersections and with structural complexity. The intersections aim to upgrade the area to a Measured Resource while providing structural and geotechnical data that strengthen the understanding of structural controls on mineralization and the mine design.

The complete list of assay results, including true thickness estimates, are presented in Table 1. In addition to the grades listed below, NUS-DD-26-08 intersected 0.6 m at 0.69 g/t Pt and 0.42 g/t Pd. This provides additional insight to previous showings of palladium and platinum previously encountered in hole NUS-DD-14-001.

The sections and plan view shown in Figures 2, 3 and 4 provide a reference to the current Measured and Indicated Resource. Section A-A’ shows a fan patterned that was aimed at a previous corridor of sparse drilling close to the area of earliest planned mine development and production. Holes such as GT-DD-26-05 were extended to assess ground conditions in areas of planned underground infrastructure. The fan confirms the presence of thicker mineralization in this area of the mineralized horizon, with intersects of up to 3.16 m in hole NUS-DD-26-04 returning copper grades above the cut-off grade of 0.3%.

The infill drilling seen in Sections B-B’, C-C’, E-E’ and F-F’ targeted shallow areas that were not tested in previous drilling, leaving this mineralized horizon unsampled and poorly defined, particularly the diabase intrusive that runs parallel to the mineralization. Holes such as NUS-DD-26-01 and NUS-DD-26-02 alleviate such issues and have subsequently yielded strong results.

Section D-D’ shows a portion of the mineralized horizon that is affected by the presence of a large fault. Consequently, previous Mineral Resource Estimates have been very conservative in this area which resulted in a break in the existing mine design. The analysis of these results constrains the fault boundaries and indicates additional tonnages extending from the known Measured Resource. Based on these findings, the Mineral Resource Estimate (MRE) will be updated, leading to an optimized mine design.

DEEP EXPLORATION DRILLING PROGRAM

Blue Moon continues to expand the high-grade, deep mineralization in the western limb of the Nussir project, following up on the recommendations outlined in the NI 43-101 Technical Report by Adam Wheeler where a high-grade intercept of 9.7 meters at 1.22% CuEq in hole NUS-DD-14-001 was identified at a depth of 1.2 km.

The Company previously announced results from this zone in its April 15, 2026 news release, showcasing 2 successful intercepts of this high-grade zone returning 1.75% Cu, 0.16 g/t Au and 27.91 g/t Ag (2.08% CuEq) over 6.7 meters (NUS-DD-1401-02 at 1,166.5 meters) and 0.86% Cu, 0.16 g/t Au and 27.75 g/t Ag (1.19% CuEq) over 3.0 meters (NUS-DD-1401-03A at 1,120.7 meters).

This additional intersection is not only encouraging for the continuity of mineralization but also its thickness between the deeper intersections from April’s press release and the existing resource defined in the 2025 Mineral Resource Estimate. Observations such as those shown in Figure 4 and the section in Figure 5, as well as those from beyond the mineralized horizon, are key to understanding the mineralization variability and zonation within the deposit. Hypotheses generated during continued studies of vein paragenesis and structural mapping strengthen the geological model and will guide further exploration programs.

SAMPLING AND QA/QC

Drill core currently produced at Nussir are in both NQ and HQ diameters; the 2026 winter-spring infill program was drilled in HQ for greater sample yield for ongoing metallurgical test work. This HQ drill core was sampled with half sawn core for metallurgical test work and quarter core for multi-element analysis. The NQ drill core, produced from all other programs, will use half core samples for multi-element analysis. The remaining half and quarter core will be retained by Blue Moon for future reference.

Starting in March 2026, Blue Moon’s samples from Q1 drilling have been shipped and delivered to ALS Piteå in Sweden. Such material has also been complemented by previously unsampled, mineralized material, from historical drill cores stored at The Geological Survey of Norway’s drill core archive at Løkken. Samples are prepared at ALS Piteå before being shipped to ALS’s facility in Ireland where they are subjected to fire assay and multi-element analysis (currently ME-ICP61 & PGM-ICP24). The ALS laboratory in Piteå maintains ISO 17025 accreditation via SWEDAC.

Sample size is stipulated to be 1 meter, while acknowledging boundaries such as lithological contacts. The current procedure is to sample 15 meters to either side of known and visual mineralization. QA/QC samples, in the form of sample blanks, duplicates and certified reference materials are currently inserted every 8^th sample, equating to an insertion rate of 12.5%. Duplicates are quarter core whilst CRM material, closely matched to the Nussir mineralization, is supplied from OREAS.
