Titan and Teck Target Germanium Recovery from Empire State Mine Waste Streams

Titan Mining has opened a technically significant critical minerals pathway at Empire State Mines in New York, signing a cooperation agreement with Teck to evaluate the recovery of germanium from material currently reporting to waste streams.

The attraction is clear: the proposed recovery route would not require a new mine, a new pit or an expanded mining footprint. It would attempt to extract a high-value critical mineral from material already moving through an existing zinc operation. 

The agreement focuses on Empire State Mines’ existing process streams, particularly the large-volume scavenger tails circuit and smaller pre-float tailings stream. Titan estimates those streams could contain about 13,000 kg a year of germanium, based on annual scavenger tailings mass of about 600,000 short tons grading 23 g/t germanium and pre-float tailings mass of about 5,400 short tons grading 69 g/t germanium. Those figures remain evaluation-stage assumptions, but they define a measurable metallurgical target rather than a broad critical minerals concept. 

The technical point is that germanium at Empire State Mines does not appear to sit with the primary zinc sulphide mineralisation. Titan’s current interpretation places it in material associated with mica and other gangue minerals, which is why it reports to processing waste rather than the payable zinc concentrate stream. That makes the recovery problem a mineral processing challenge: upgrade the right stream, meet downstream feed specifications and establish whether the material can be treated commercially through an existing germanium recovery circuit. 

Teck’s role gives the work industrial weight. Trail Operations in British Columbia is the only commercial-scale facility in North America recovering germanium from primary sources, giving the cooperation agreement a direct link between an operating US mine and an established North American critical minerals processing platform. The parties will evaluate upgraded Empire State Mines process streams as a potential feedstock for Trail, define minimum feed specifications and assess commercial terms that could support long-term offtake.

The story sits at the intersection of three trends: critical mineral recovery from non-traditional streams, higher-value use of tailings and the push to extract more value from existing operating footprints. If successful, the project would not change the fundamental mining method at Empire State Mines. Its impact would come from circuit intelligence, mineralogical understanding and the ability to identify a recoverable critical mineral stream inside material previously treated as waste.

The timing is commercially sharp. Germanium is used in infrared optics, semiconductor and chip manufacturing, fibre optics and communications infrastructure. North America has limited domestic supply and processing capacity, while germanium pricing cited by Titan for US warehouses was US$5,800 to US$8,600/kg as of April 30, 2026. Those price levels explain why a relatively small contained mass can attract serious attention when the recovery path uses existing mine and plant infrastructure. 

The agreement also fits Titan’s wider shift from a single-commodity zinc profile toward a multi-critical-minerals platform. In Q1 2026, Titan produced 14.2 million payable pounds of zinc, began initial shipments of natural flake graphite concentrate from its Kilbourne Graphite Project and continued evaluation work on germanium recovery from existing process streams. That gives the company exposure to zinc, graphite and germanium from the same upstate New York operating base. 

The next test is technical, not promotional. Titan and Teck need to establish whether the germanium-bearing streams can be upgraded consistently, whether impurity levels fit the Trail circuit and whether payability supports a commercial offtake structure.

If those conditions are met, Empire State Mines could become a case study in how mature base-metals operations can generate new critical minerals output without waiting for greenfield development.
