Germanium Mining completes summer field work at Lac du Km 35

Germanium Mining Corp. Completes Summer Field Work and Awaits Assay Results at its 100% Owned Lac du Km 35 Germanium Property in Québec

(TheNewswire)

V ANCOUVER, BRITISH COLUMBIA – TheNewswire - SEPTEMBER 23, 2026 – GERMANIUM MINING CORP. (“GERMANIUM MINING” OR THE “COMPANY”) (CSE: GMC; OTCQB: EMSKF; FSE: YW0) is pleased to announce that Summer Field Work, consisting of systematic and detailed mapping and sampling with an emphasis on the Laganière showing area, was completed. A total of 192 outcrops were mapped and sent to the laboratory a total of 115 rock samples that will be assayed for, among others, germanium, copper, zinc and gold. Another 5 samples were also included for quality control purposes for a total of 120 samples. The Company expects to get assay results by mid-October 2026.

Mario Pezzente, Chief Executive Officer, commented: “We have strategically expanded our 100% owned Lac du Km 35 Germanium property ahead of the active 2026 exploration season to allow for potential additional discoveries contiguous to the north of the Laganière showing that hosts the highest-grade Germanium sample in the Province of Quebec at 186 ppm . We are excited to receive shortly TDEM survey results with a goal of outlining new conductors in the vicinity of the Laganière Germanium showing on this highly prospective critical metal project. Germanium Mining Corp. is focused on unlocking strategic resources in stable jurisdictions, to potentially contribute to a more secure and resilient North American supply chain.”

Magnetic Airborne Survey Results

The survey covered the whole Property at a line spacing of 50 metres which allowed a clear and accurate outline of the Faribault Shear zone, particularly near the Laganière showing area. Towards the southern boundary of the property, an East-Northeast structure was also outlined transecting mafic and ultramafic intrusives, consisting of an assemblage of gabbro and pyroxenites. Both these areas, the Laganière Germanium showing and that East-Northeast structure were prospected in details.

The survey also highlighted a new East-West corridor that is approximately 3 kilometres long by 1 kilometre wide near the western edge of the property. This corridor within a low magnetic area represents a new sector prospective for gold. A short mapping and sampling program along this new corridor is expected to begin soon this Fall.

Electromagnetic Ground Survey Results

The immediate area of 1.4 kilometres by 1.4 kilometres surrounding the Laganière showing was surveyed at a line spacing of 100 metres and stations at every 25 metres. Strong conductors were outlined underneath the Laganière Germanium showing at depth. Modelling and interpretation of these conductors will determine their approximate depth and allow diamond drill targeting.

In addition, new and strong conductors were also defined on the southwestern portion of the electromagnetic survey grid. These conductors will be modelled and interpreted as well and represent potential drill targets. Surface expressions of these conductors were prospected during Summer Exploration Program.

Upcoming Diamond Drilling Program

Upon receiving assay results and interpretation of the ground electromagnetic survey, Germanium Mining will begin drill targeting and apply for drill permits. The first phase of diamond drilling will aim to reach the “discovery hole” stage. The campaign is planned to consist of 6 to 10 holes for a total of approximately 2,500 metres that is planned to be drilled early in 2027.

Current sample results returned approximately 0.02% (186 ppm) Germanium at the Laganière showing, currently the highest-grade Germanium sample in the Province of Quebec to date.

Lac du Km 35 Property

The 100% owned Lac du Km 35 Germanium Property is approximately 40 km east of the mining town of Chibougamau in the Nord-du-Québec region of Québec and offers excellent access via Highway 167 and a main logging road that intersects the Property.

The Property comprises the prominent Faribault Shear Zone (“FSZ”), oriented east-southeast, and located towards the eastern part of the Property. The FSZ dips to the south-southwest and ends to the Grenville Front which extends southwest-northeast for several hundreds of kilometres. The FSZ is a key structural feature that may connect with other permeable zones at depth, acting as a preferential conduit for hydrothermal fluids.

Discovered by government geologists in 1998 and never followed up, the Laganière Germanium showing consists of a peridotite outcrop within the Laganière gneissic Complex that comprises amphibolites and hornblende and biotite gneisses. The Laganière showing returned a value of 0.02% (186 ppm) germanium and is currently the highest germanium value ever reported from an outcrop in the province of Québec.

The Laganière germanium showing is also 450 m northeast of the FSZ, 800 m from the southern margin of the Duberger felsic pluton and approximately 2 km to the west of the Grenville Front. The area between the FSZ and the Laganière Germanium showing, including electromagnetic anomalies, was never drill-tested and will be the main focus of GMC.

About Germanium

Germanium is a hard, greyish and brittle metalloid. Germanium has many growing applications in electronics and solar, in fiber optics, and Infrared optics for civil and military uses. Germanium is in the list of critical metals in Canada, the United States and the European Union.

Since December 3, 2024, China, the largest producer of refined germanium, has banned germanium exports to the United States. Germanium is not an openly traded commodity and recent spot prices have germanium over US$5,000 per kilogram.
