Inside Information: Endomines and Wolfram Bergbau und Huetten AG signed non-binding Letter of Intent (LOI) regarding tungsten collaboration

Endomines Finland Plc has signed a non-binding Letter of Intent (LOI) with Wolfram Bergbau und Huetten AG (Wolfram) to investigate possibilities to cooperate in the field of tungsten.

The purpose of the LOI is to establish a framework for collaboration between the parties in areas including, but not limited to:

• Technical cooperation in research, development, and innovation related to tungsten mining and beneficiation, with the objective of producing a concentrate suitable for Wolfram’s refinery in Austria.
• Exchange of expertise and best practices in processing, quality control, and sustainability.
• Evaluation of a potential commercial offtake agreement, balancing quality, recovery, and processing costs.

“Tungsten is one of the 14 critical minerals defined by the European Union. Endomines submitted an EU Strategic Project application for its Southern Gold Line tungsten, molybdenum and gold project in January. We are excited to work together with Wolfram to assess possibilities for long-term cooperation. Technical cooperation during the permitting and engineering phases also supports the design of production facilities capable of delivering marketable products. Tungsten supply is highly concentrated, making the material strategically important for critical industrial value chains and for Endomines,” says Kari Vyhtinen, CEO of Endomines Finland Plc.

“We welcome the opportunity to explore potential cooperation with Endomines, aligned with our shared focus on responsible and resilient tungsten supply," says David Goulbourne, President of Wolfram Bergbau und Huetten AG.
