Germanium Mining Corp. Joins Critical Minerals Institute

GERMANIUM MINING CORP. (“GMC” or the “Company”) has joined the Critical Minerals Institute (“CMI”), an international organization focused on the critical minerals economy. The Company says the move is intended to strengthen its engagement with institutional investors, government decision-makers, and industry leaders involved in critical mineral supply chains.

CMI membership and upcoming summit

CMI membership provides access to monthly CMI Masterclasses, the weekly Critical Minerals Report, bespoke research, and board-level advisory services covering exploration, finance, supply chain strategy, and geopolitics. CMI also organizes its flagship Annual Critical Minerals Institute Summit.

The upcoming CMI Summit V, themed “The New Critical Minerals Economy,” is scheduled for May 13–14, 2026 in Toronto, Canada. The Company said the summit will bring together government leaders, institutional investors, and industry executives.

Lac du Km 35 Germanium Project: funding close and 2026 exploration planning

Germanium Mining previously announced on April 2, 2026 the closing of the first tranche of funding for its 2026 exploration programs at its 100%-owned Lac Du Km 35 Germanium Project. The project hosts the Laganière showing, which returned 0.02% germanium (186 ppm) and is described as the highest germanium value ever reported from an outcrop in Québec.

Planning for drill permit applications and a 2026 property-wide airborne magnetic and electromagnetic survey is underway. The Company said the survey will help identify high-priority exploration targets for the upcoming field season by mapping electromagnetic and magnetic conducting anomalies and structural features.

The airborne survey data will be integrated with recent remote sensing results, which have outlined new structural corridors and circular features interpreted to be potentially prospective for germanium mineralization. The Company said the combined datasets are expected to refine and prioritize areas for outcrop sampling ahead of a first phase drilling program.

Laganière showing and nearby structural targets

At the Laganière Germanium showing, remote sensing identified a prominent circular feature approximately 300 metres in diameter, with the nature of the feature described as unknown. The Company said the target is further enhanced by three northeast-trending structural corridors intersecting the showing area, which may suggest pathways for mineralizing fluids.

In addition, the Faribault Shear Zone (“FSZ”), located approximately 450 metres southwest of the Laganière showing, has been clearly defined through imagery and is described as a regionally significant structural control that may be linked to mineralization.

Geophysical data compilation and mapping

All newly acquired airborne geophysical data, together with remote sensing interpretations, will be compiled into a GIS platform to generate detailed 1:5,000 scale maps. The Company said these outputs will be used to optimize fieldwork, logistics, and final drill collar locations as it moves toward initial drilling.

Regional setting of the Lac du Km 35 Property

The Lac du Km 35 Property is located 40 kilometres east of Chibougamau in Quebec’s Nord du Québec region. The Company said the area has road access via Highway 167 and a network of forestry roads.

The project covers volcano-sedimentary rocks of the Roy Group and the Laganière Gneissic Complex within the northeastern Abitibi greenstone belt near the Grenville Front, described as a major structural boundary.

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

The Laganière germanium showing was discovered by government geologists in 1998 and has not been followed up. The Company said the showing consists of a peridotite outcrop within the Laganière gneissic Complex comprising amphibolites and hornblende and biotite gneisses. It reported 0.02% (186 ppm) germanium and described it as the highest germanium value ever reported from an outcrop in Québec.

The Company said the Laganière showing lies beside the main lumber road and is immediately adjacent to a cluster of electromagnetic anomalies roughly 400 m x 400 m in size that were never tested. It also said the showing is 450 m northeast of the 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 showing, including the untested electromagnetic anomaly cluster, is described as the main focus of GMC.

New airborne magnetic and electromagnetic survey

Magnetic and electromagnetic data are available from Quebec government sources near the main Laganière Germanium showing. The Company said the existing data were acquired in 1978, nearly 50 years ago, with line spacing of 200 metres and elevation from the surface of 120 metres.

GMC intends to conduct a new, modern, detailed airborne magnetic and electromagnetic survey covering the entire Lac Du Km 35 property. The Company said the survey is expected to be flown as weather allows in April 2026, with planned line spacing not exceeding 75 metres and elevation from the surface below 30 metres.

The Company said the updated data will be used to confirm existing anomalies and potentially outline new ones to be verified during the upcoming summer field season.

Germanium context and market notes

The Company described germanium as a hard, greyish and brittle metalloid used in electronics and solar applications, as well as fiber optics and infrared optics for civil and military uses. It said germanium is listed as a critical metal in Canada, the United States, and the European Union.

GMC also noted that since December 3, 2024, China—the largest producer of refined germanium—has banned germanium exports to the United States. The Company said germanium is not an openly traded commodity and that recent spot prices have been above US$5,000 per kilogram.

The Company cautioned that the geological information provided in the release is historical and that mineralization may not be representative of mineralization on the Lac du Km 35 Property.
