(via TheNewswire)

VANCOUVER, BRITISH COLUMBIA – TheNewswire - JUNE 2, 2026 – GERMANIUM MINING CORP. (“GERMANIUM MINING”, “GMC” OR THE “COMPANY”) (CSE: GMC; OTCQB: EMSKF; FSE: YW0) is pleased to announce that the 100% owned Lac du Km 35 Germanium Property was strategically expanded by staking 18 mineral claims, representing an additional 995 hectares (9.95 km2 ).  The expanded Property now consists of 99 contiguous mineral claims covering an area of 54.8 km2 , encompassing the most promising areas for Germanium exploration. These newly acquired claims are immediately north of the Laganière Germanium showing area, thus providing an important and strategic expansion zone should a discovery be made throughout the upcoming 2026 exploration season.  

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 commence this multi-stage exploration program with a goal of making new Germanium discoveries on this highly prospective critical metral 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.”

Exploration Program

Upcoming 2026 exploration will include a highly sensitive magnetic airborne survey as well as a ground electromagnetic survey to potentially identify Germanium that could be associated with lower conductivity silver-zinc mineralization.

These surveys will aim to identify possible additional shear zones and electromagnetic anomalies for the upcoming sampling and assaying program.  Most, if not all features of interest such as shear zones, magnetic and electromagnetic anomalies, will be verified on the field, early in the planned 2026 exploration program. The immediate area of the Laganière showing will be further explored and sampled and assayed allowing GMC to deliver diamond drill targets that could be tested in the Fall of 2026.

The first phase of diamond drilling will be directed 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 Winter 2026.

The exact drilling length will be dictated by the depth of the electromagnetic anomalies that will be accurately outlined by the new survey and backed up by outcrop mapping and sampling.  The outcrop mapping will provide valuable insights into what direction and dip that germanium mineralization may extend.

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. The Company aims to increase Germanium grades at least to 0.04% (350 – 400 ppm) with an average intersection at least 10 metres wide.

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 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.

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.

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