Germanium Mining Corp. Options Pluto Property to XXIX Metal Corp., Focuses on Germanium Assets

VANCOUVER, BRITISH COLUMBIA — June 23, 2026 — Leads & Copy — GERMANIUM MINING CORP. (CSE: GMC; OTCQB: EMSKF; FSE: YW0) has optioned its Pluto Property to XXIX Metal Corp. in a deal that could see XXIX Metal Corp. incur significant exploration expenditures and grant Germanium Mining Corp. a net smelter returns royalty. This strategic move allows Germanium Mining Corp. to concentrate on its core business of advancing germanium assets.

Under the terms of the Option Agreement, XXIX Metal Corp. will pay $50,000 in cash upon execution and an additional $50,000 in shares near December 18, 2026. The number of shares will be based on the 20-day volume-weighted average price. Furthermore, XXIX Metal Corp. is committed to spending at least $250,000 on exploration expenditures on the Pluto Property by December 2028.

Should XXIX Metal Corp. exercise its option, it will grant Germanium Mining Corp. a 2% net smelter returns royalty (NSR). XXIX Metal Corp. retains the right to reduce this NSR to 1% by making a cash payment of $750,000 to Germanium Mining Corp.

The Pluto Property, situated approximately 10 kilometres west of Chapais in Québec's Nord-du-Québec region, comprises 10 mineral claims covering 555.8 hectares. This option agreement aligns with Germanium Mining Corp.'s objective to unlock strategic resources in stable jurisdictions and contribute to a more secure North American supply chain.

Germanium, a critical metal essential for electronics, solar, fiber optics, and infrared optics, is in high demand. Its importance is underscored by its inclusion on the critical metals lists of Canada, the United States, and the European Union. Notably, China, the leading producer of refined germanium, has restricted exports to the United States since December 3, 2024. Current spot prices for germanium exceed US$5,000 per kilogram.

Mario Pezzente, Chief Executive Officer of Germanium Mining Corp., stated that the company will now focus its efforts on developing germanium assets. Benoit Moreau, P.Eng., vice-president of exploration for Germanium Mining Corp. and a qualified person under National Instrument 43-101, has overseen the technical information in this release.

Germanium Mining Corp. is a publicly traded mineral exploration company focused on advancing discovery-stage mineral properties in North America. The company is listed on the Canadian Securities Exchange under the ticker GMC, on OTCQB as EMSKF, and on the Frankfurt Stock Exchange as YW0.
