Seeking to turn mine waste into a new source of critical minerals, Titan Mining Corp. announced that it has entered into an agreement with Teck Resources Ltd. to evaluate the recovery of germanium from existing processing streams at its Empire State Mines in upstate New York.

Located in St. Lawrence County in northern New York, about 30 miles south of the Canadian border, Empire State Mines is home to one of the Northeast’s longest-running zinc districts, where several mines have operated intermittently for more than a century and hoisted mineralized material containing roughly 8.7 billion pounds of zinc.
Long produced as a base-metal district, Empire State is now being evaluated for a critical mineral that typically follows zinc through the mining and processing chain rather than being mined on its own.
A little-known semiconductor metal, germanium is used in infrared optics for defense systems, fiber optic and communications infrastructure, solar cells, light-emitting diodes, semiconductors, and advanced chip manufacturing.
Like many critical minerals, germanium is generally not mined as a primary metal. Instead, it is typically recovered as a byproduct of zinc processing, making supply dependent on the mines, smelters, and refineries capable of separating it from larger base-metal streams.
Within Titan’s Empire State project, however, the germanium is not tied to the primary zinc sulfide mineralization, causing it to bypass the main zinc concentrate and report instead to processing waste streams.
According to the company, about 28,660 pounds (13,000 kilograms) of germanium could be flowing into those waste streams each year, based on roughly 600,000 short tons (544,000 metric tons) of annual scavenger tailings grading 23 grams per metric ton germanium and 5,400 short tons (4,900 metric tons) of pre-float tailings grading 69 g/t germanium.
To determine whether that material can be processed through an established germanium recovery circuit, Titan Mining has entered into a cooperation agreement with Teck to evaluate whether germanium-bearing material at Empire State Mines, particularly from the large-volume scavenger tails circuit, can be upgraded into feedstock suitable for Teck’s Trail Operations in southern British Columbia.
“This is a clear example of our focus on extracting maximum value from our existing operations. Germanium at Empire State Mines sits in material that is currently treated as waste,” said Titan Mining CEO Rita Adiani. “By working with a credible processing partner that operates an established large-scale metallurgical facility, we have the potential to generate incremental cash flow without additional mining.”
Located in southern British Columbia, Teck’s Trail Operations is a zinc and lead smelting and refining complex that also recovers precious metals such as silver and gold, as well as critical metals including germanium, indium, and cadmium from concentrates shipped from the Red Dog Mine in Alaska and elsewhere.
As operator of both Red Dog and Trail Operations, Teck has long been one of North America’s most important sources of germanium, producing high-quality material used in fiber optic cables, high-speed computer chips, quantum computer transistors, solar cells, LEDs, and night vision goggles.
Trail is also the only commercial-scale facility in North America recovering germanium from primary sources, giving Titan a potential processing pathway if the Empire State material meets technical and economic requirements.
Under the agreement, Titan and Teck will evaluate upgraded Empire State process streams as a potential germanium-bearing feedstock for Trail, define the minimum feed specifications required by the Trail circuit, and assess commercial parameters including potential volumes and payability with a view toward long-term offtake arrangements.
“This agreement with Titan underscores Teck’s commitment to strengthening North America’s supply of critical minerals essential to defense, semiconductor production, and advanced chip manufacturing,” said Teck Chief Commercial Officer Ian Anderson. “Teck is one of the world’s largest global producers of germanium, a key supplier of germanium to the U.S., and this partnership builds on our long-standing leadership in critical-mineral production.”
The companies said the work is intended to support a possible transition into a commercial agreement, subject to technical and economic results.
“Working with Teck allows us to evaluate this opportunity alongside a partner with proven recovery capabilities, while supporting the development of a more secure domestic supply of a critical mineral,” Adiani said.
With germanium pricing in U.S. warehouses ranging from $5,800 to $8,600 per kilogram as of April 30, Titan said the initiative could create a meaningful new revenue opportunity while supporting domestic supply of a material essential to defense, semiconductor, and communications applications.
If successful, the cooperation agreement would add germanium to Titan’s growing list of critical minerals opportunities at Empire State Mines, where existing zinc operations, graphite development, and now waste-stream recovery are being positioned around a broader effort to rebuild domestic supply chains for materials used across defense and advanced technology manufacturing.
