TITAN MINING ENTERS INTO COOPERATION AGREEMENT WITH TECK'S TRAIL OPERATIONS TO EVALUATE GERMANIUM RECOVERY FROM EXISTING MINE WASTE STREAMS

Titan Mining Corp. has entered into a co-operation agreement with Teck Resources Ltd. to evaluate the recovery of germanium (Ge) from existing processing streams at its Empire State Mines (ESM), representing a potentially new significant revenue opportunity and supporting domestic supply of materials essential for defence, semi-conductors and chip manufacturing. Teck's Trail operations is the only commercial-scale facility in North America recovering germanium from primary sources.

Highlights

• Unlocking value from waste streams: The co-operation agreement contemplates evaluation of the potential for approximately 13,000 kilograms/year of contained germanium within existing ESM process streams.
• Substantial cash flow potential: Initial review indicates strong economics, creating the opportunity to generate potential additional cash flow from material already being processed.
• No additional mining required: Germanium is hosted in material currently reporting to waste streams, offering a pathway to recovery from existing operations.
• Capital-efficient strategy: Leverages existing mining and processing infrastructure without expanding mining footprint.
• Strategic partnership with established processor: Collaboration with Teck, which has an established North American germanium recovery platform at Trail.
• Aligned with United States critical minerals strategy: Supports domestic supply of germanium, a material essential to defence, semiconductors and communications applications.

Strategic overview

Germanium is a critical mineral used in:

• Defence applications, including infrared optics;
• Semiconductor and chip manufacturing;
• Fibre optic and communications infrastructure.

The United States currently has limited domestic supply and processing capacity, increasing the importance of new, secure sources.

At ESM, germanium occurs within material not associated with the primary zinc sulphide mineralization. As a result, it currently reports to processing waste streams rather than being recovered.

These waste streams, particularly the large-volume scavenger tails circuit, represent a potentially meaningful and currently unmonetized source of contained germanium.

This initiative is designed to evaluate a capital-efficient pathway to unlock a critical mineral from material that is already mined and processed, without requiring additional mining activity.

Rita Adiani, chief executive officer of Titan Mining, commented:

"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. 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.

"With strong pricing in U.S. warehouses ranging from $5,800 to $8,600/kg and limited domestic supply, this initiative positions Titan to potentially become a meaningful supply chain partner for domestically sourced germanium into U.S. defence and advanced technology supply chains in a capital-efficient and timely manner.

"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."

Ian Anderson, Teck executive vice-president and chief commercial officer, commented:

"This agreement with Titan underscores Teck's commitment to strengthening North America's supply of critical minerals essential to defence, semiconductor production and advanced chip manufacturing. 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."

Co-operation agreement scope

Under the agreement, Titan and Teck will:

• Evaluate upgraded ESM process streams as a potential germanium-bearing feedstock for Trail operations;
• Define minimum feed specifications required by the Trail circuit;
• Assess commercial parameters, including potential volumes and payability with a view toward entering into long-term offtake arrangements.

The parties will work collaboratively with a view toward transitioning to a commercial agreement, subject to technical and economic results
