Germanium Mining Corp. Completes Remote Sensing Work on Lac Du Km 35 Property

VANCOUVER, BRITISH COLUMBIA — March 12, 2026 — Leads & Copy — GERMANIUM MINING CORP. has completed remote sensing work on its Lac Du Km 35 Property, located in the Chibougamau area, Quebec.

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 lies beside the main lumber road and immediately adjacent to the south to a cluster of electromagnetic anomalies of roughly 400 m x 400 m in size that were never tested. 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 the never tested cluster of electromagnetic anomalies, will be the main focus of GMC.

The remote sensing work allowed the identification of new structural and circular features that may be associated to germanium mineralization.

The satellite imagery study used ESA (European Space Agency) PNEO satellites constellation with panchromatic data of 30 cm in resolution, acquired in September 2023. A pan sharpened image was acquired with visible and infrared bands.

Image has been acquired in September 2023 and is of high quality. Algorithms were applied on these images in order to pinpoint relevant structural bodies, including potential intrusions, variably dipping dykes and lenticular-shaped elements as well as outlining potential outcrops.

Major structures and circular features have been identified on property with main trends being NE, EW, NNE, and NW. Many structures coincide with the Ministry Québec government structural maps and new major structures have also been identified.

The Laganière germanium showing area is correlated with a circular feature having a diameter of approximately 300 metres; the exact nature of this circular feature is still unknown and will be investigated. The Laganière showing area is also crosscut by a set of 3 major NE structures. Finally, the important Faribeault Shear Zone, roughly 450 metres southwest of the Laganière germanium showing, has been clearly mapped from the image.

In addition, the remote sensing work allowed the outline of several outcropping areas nearby the Laganière germanium showing. It is expected that between 15 to 20 potential outcrops per line-kilometre would be mapped and sampled in the upcoming program in the summer of 2026.

The information will be transferred to a GIS system and a series of maps at scale 1:5,000 will be generated. Precise satellite image interpreted structural features will help optimizing the field campaign and logistics.

Germanium is a hard, greyish and brittle metalloid with 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.
