Blue Moon Metals Inc. ("Blue Moon" or the "Company") (TSXV:MOON) (NASDAQ:BMM) is pleased to provide assay results from its maiden bulk sample at the past-producing Apex germanium-gallium-copper mine located in Utah ("Apex" or the "Project").

This initial sampling program represents the first results following the closing of the acquisition of Apex from a subsidiary of Teck Resources Limited on March16, 2026. A 100kg sample was obtained from Apex and sent to the laboratory for analysis ahead of metallurgical testing. The sample was crushed and blended, with assay results highlighting 0.180% germanium, 0.0273% gallium and 1.96% copper. With assay results in hand, Blue Moon will continue with its planned metallurgical program to determine its own flowsheet options and also explore near term commercialization options.

Prices of germanium and gallium have seen material increases in recent months, with Fastmarkets estimating (as of June26, 2026) current spot prices for Rotterdam delivery of germanium and gallium metal of $10,500/kgGe and $2,650/kgGa. See Blue Moon's press release from February27, 2026 for disclosure on historical production and historical reserve estimates from Apex.

In parallel with site activities, Blue Moon is exploring the potential to sell direct shipping ore ("DSO") from Apex. This possibility of selling DSO owes to the high-grade nature of the primary germanium-gallium mineralization mined historically at the Project, and the constrained germanium market ex-China. The Company has received unsolicited interest from several major users and producers of germanium and gallium products. Permitting activities are ongoing, targeting a Q2-2027 completion of mine permitting following the relevant government permitting processes. Discussions on contract mining have also begun, with the view of potentially starting DSO from Apex as soon as Q3-2027. At a mining rate of 150 tpd, Apex could potentially supply nearly 100% of the domestic U.S. germanium demand from one U.S. supply source.

Sampling and Analytical Method

The samples reported in this news release are samples collected from exposed mineralization at Apex. These samples are selective in nature and are not necessarily representative of the average grade or size of the mineralized zone. All samples were stored and shipped using industry best practices and were delivered to Blue Coast Research Ltd. ("Blue Coast"), Parksville, British Columbia, for sample preparation and analyses using Peroxide Fusion. Blue Coast is an independent commercial laboratory.
