Germanium Mining Corp. Completes TDEM Survey, Awaiting Report on Potential Mineralization

VANCOUVER, BRITISH COLUMBIA — July 3, 2026 — Leads & Copy — GERMANIUM MINING CORP. (CSE: GMC; OTCQB: EMSKF; FSE: YW0) has completed a Time Domain Electro Magnetic (TDEM) survey on its 100% owned Lac du Km 35 Germanium property in Quebec. The final report, expected in the coming days, will detail potential anomalies within a 1,400-metre by 1,400-metre area that includes historical input anomalies and the Laganière showing. The company aims to identify existing and new conductors that could indicate the presence of Germanium-Silver and Zinc mineralization.

In parallel, an airborne magnetic survey covering the entire property has begun, with results anticipated by mid-July 2026. Potential magnetic anomalies identified by this survey will be investigated during an upcoming outcrop mapping and sampling program. The Lac du Km 35 Germanium Property is situated approximately 40 km east of Chibougamau, Quebec, accessible via Highway 167 and a logging road.

Mario Pezzente, Chief Executive Officer, stated that the property was strategically expanded to facilitate potential discoveries north of the Laganière showing, which holds the highest-grade Germanium sample in Quebec at 186 parts per million (ppm). Germanium Mining Corp. is focused on developing prospective mineral properties in Canada, aiming to contribute to a more secure North American supply chain for critical metals. Germanium is listed as a critical metal by Canada, the United States, and the European Union, with applications in electronics, solar technology, fiber optics, and infrared optics.

The exploration program is designed to locate additional shear zones and electromagnetic anomalies for subsequent mapping and sampling, scheduled to commence in mid-July 2026. The Laganière showing area will undergo further exploration and sampling, with assay results expected to guide the selection of diamond drill targets for early 2027. The initial diamond drilling phase, planned for early 2027, will involve 6 to 10 holes totaling approximately 2,500 metres, contingent on the depth of electromagnetic anomalies confirmed by the new surveys and outcrop mapping.

Current sample results from the Laganière showing have yielded approximately 0.02% (186 ppm) Germanium, representing the highest-grade Germanium sample from an outcrop in Quebec to date. This showing is located within the Laganière gneissic Complex, adjacent to the main lumber road and a cluster of untested electromagnetic anomalies measuring roughly 400 m x 400 m. The Laganière Germanium showing is also positioned 450 m northeast of the Faribault Shear Zone (FSZ), 800 m from the southern margin of the Duberger felsic pluton, and approximately 2 km west of the Grenville Front. The area between the FSZ and the Laganière Germanium showing, including the untested electromagnetic anomalies, will be a primary focus for the Company.

Germanium, a hard, greyish, and brittle metalloid, has growing uses in various technological sectors. China, the largest producer of refined germanium, implemented export bans to the United States in December 2024. Germanium is not an openly traded commodity, with recent spot prices exceeding US$5,000 per kilogram.

Benoit Moreau, P.Eng., vice-president of exploration for Germanium Mining Corp., has prepared and is responsible for the technical information in this news release. The company is focused on the development of discovery-stage mineral properties in prominent Canadian mining jurisdictions.
