First Tin Makes New Critical Mineral Discovery in German Mine Project

UK-based junior mining company First Tin (LSE:1SN) has confirmed the widespread presence of various critical mineral resources, including gallium and indium, within its Auersberg and Gottesberg exploration license areas in Germany.

Additionally, First Tin has compiled sampling results from exploration work conducted from 2024 to 2025, along with historical data from the former German Democratic Republic. The findings indicate that, in addition to tin, gallium, and indium, the company has also discovered significant quantities of other critical raw materials, such as lithium, cesium, and rubidium.

The company stated that, given that the EU has classified gallium and lithium as critical raw materials, these discoveries will further enhance the strategic importance of the project within the EU.

Within a three-kilometer radius, First Tin has mapped and sampled several tin-quartz veins (Greisen), revealing the potential presence of a large mineralized system that may contain tin with grades ranging from 0.2% to 0.6%, along with associated critical mineral by-products. Furthermore, the presence of silver and bismuth has also been identified in some of the tin mineralized zones.

Bill Scotting, CEO of First Tin, commented, "Our company holds a series of exploration licenses in the 'Tin Triangle' region (which is adjacent to the known Tellerhauser and Gottesberg deposits). Preliminary exploration results indicate significant development potential within the areas covered by these licenses."

"Moreover, the substantial potential of these areas in terms of other critical minerals holds particular significance for Europe's current efforts to establish a secure supply chain for critical minerals."

In its 2025 fieldwork plan, the company expects to conduct further work to assess the value of these newly discovered mineral resources.
