GERMANIUM MINING CORP. ADVANCES FUNDS FOR THE LARGEST MODERN EXPLORATION PROGRAM TO DATE ON ITS 100% OWNED LAC DU KM 35 GERMANIUM PROJECT

Germanium Mining Corp. has advanced funds and secured its exploration team for the phase one work program at its 100-per-cent-owned Lac du Km 35 germanium project located in the Chibougamau region of Quebec, Canada.

This upcoming 2026 work season will be the largest financed modern exploration on the property, providing opportunities for additional discoveries. An expanded sampling program will focus on outcrops and high-priority targets with assay results anticipated to follow, with the company's application for drilling permits quickly thereafter. The first drilling campaign is anticipated follow in the early wintertime.

Mario Pezzente, chief executive officer, commented: "Our 100-per-cent-owned Lac Du Km 35 germanium property currently hosts the highest-grade germanium samples in the province of Quebec of 186 ppm from the Laganiere showing. We are excited to commence this multistage 2026 exploration program with a goal of making new germanium discoveries on this highly prospective critical mineral 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."

About the 2026 exploration program

The first phase of diamond drilling will be directed to reach the discovery hole stage. The campaign is planned to consist of six to 10 holes for a total of approximately 2,500 metres that is planned to be drilled late 2026/early 2027.

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 per cent (186 ppm) germanium at the Laganiere 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 per cent (350 to 400 ppm) with an average intersection at least 10 metres wide.

Anticipated 2026 to 2027 exploration timetable

May, 2026 -- airborne survey results, including interpretation

June/July, 2026 -- outcrop mapping and sampling program -- (as soon as the snow melts)

September, 2026 -- outcrop sampling assay results

October/December, 2026 -- drill permitting

Description of the Lac du Km 35 property regional setting

The property comprises the prominent 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 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 Laganiere germanium showing consists of a peridotite outcrop within the Laganiere gneissic complex that comprises amphibolites and hornblende and biotite gneisses. The Laganiere showing returned a value of 0.02 per cent (186 ppm) germanium and is currently the highest germanium value ever reported from an outcrop in the province of Quebec.

The Laganiere germanium showing lies beside the main lumber road and immediately adjacent to the south to a cluster of electromagnetic anomalies of roughly 400 metres by 400 metres in size that were never tested. The Laganiere germanium showing is also 450 m northeast of the FSZ, 800 m from the southern margin of the Duberger felsic pluton and approximately two km to the west of the Grenville Front. The area between the FSZ and the Laganiere germanium showing, including the never tested cluster of electromagnetic anomalies, will be the main focus of GMC.

New airborne magnetic and electromagnetic survey

Magnetic and electromagnetic data are currently available from Quebec government sources where a cluster of electromagnetic anomalies are present in the vicinity of the main Laganiere germanium showing. However, all these magnetic and electromagnetic data were acquired nearly 50 years ago in 1978. At the time, line spacing and elevation from the surface were respectively 200 and 120 metres.

The company intends to carry out a new, modern, detailed and more accurate airborne survey that will cover the whole Lac Du Km 35 property. It is expected that the survey will be flown as weather allows in April, 2026. For this airborne survey, line spacing not exceeding 75 metres and elevation from surface below 30 metres are planned. These modern data will help to confirm existing anomalies and, possibly, outline new ones that will be verified on the ground in the upcoming summer field season.

2026 germanium price and performance

Germanium prices are increasingly influenced by the tension between rising strategic demand and a market constrained by export controls and tight global supply. At today's price of $8,597.50 (U.S.) per kilogram, Germanium prices are up 47.88 per cent year to date (2026), up 108.64 per cent since the start of 2025, up 202.79 per cent since the start of 2024 and up 320.40 per cent since the start of 2020, when the germanium price stood at $2,045.09 per kg. This reflects germanium's importance in fibre optics, infrared technology, semiconductors and defence-related applications, combined with a market where supply remains concentrated and access outside China can tighten quickly.

Key price drivers for germanium

Expanding applications:  growing use in fibre optics, infrared systems and advanced semiconductor applications

Supply concentration:  China controls 93 per cent of global production with increasing export restrictions

Strategic designation:  classification as "critical metal" by major economies driving stockpiling

Irreplaceability:  few viable substitutes exist for germanium's unique properties in key applications

About germanium

Germanium is a hard, greyish and brittle metalloid. Germanium has many growing applications in electronics and solar, in fibre 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 Dec. 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 at approximately $8,600.00 (U.S.) per kilogram.

Non-brokered private placement

Furthermore, the company is pleased to announce it has closed the non-flow-through (NFT) portion of its previously announced non-brokered private placement (see news release March 20, 2026, and April 2, 2026) totalling 3,477,750 million units at 24 cents per unit for gross proceeds of $834,660. Each unit consists of one common share and one transferable common share purchase warrant. Each warrant entitles the holder to purchase one additional share of the company at 32 cents per share for a period of 24 months from the date of issuance.

The net proceeds from the NFT placement will be allocated for general corporate purposes including arm's-length payables. No finder's fee was payable on this tranche of the financing. All securities issued pursuant to the private placement will be subject to a hold period of four months and one day as required under applicable securities legislation.
