First Tin PLC

("First Tin" or "the Company")

Letter of Interest from Export-Import Bank of the United States

First Tin PLC, a tin development company with advanced, low-capex projects in Australia and Germany, announces that it has received a non-binding Letter of Interest ("LI") from the Export-Import Bank of the United States ("EXIM"), outlining potential financing support for the Company's Taronga Tin Project ("Taronga") in New South Wales, Australia.

The LI indicates EXIM's capacity to consider up to US$120 million in financing for a maximum repayment term of 12 years. The potential facility would support development of Taronga, linked to the supply of tin concentrate to the U.S., which currently has no domestic tin mine production.

Taronga is among the world's most advanced undeveloped tin assets, with a large and growing reserve and resource base. Its location in a stable, transparent jurisdiction with strong ESG standards offers clear advantages for offtake partners seeking responsible, traceable, and conflict-free supply chains. The project may qualify for special consideration under EXIM's China and Transformational Exports Program (CTEP), aimed at strengthening U.S. supply chain resilience in critical minerals.

Upon formal application, EXIM will undertake its standard due diligence prior to issuing any final commitment, which must meet all program, legal, and eligibility requirements.

First Tin CEO, Bill Scotting, commented:

"This Letter of Interest from EXIM is a strong endorsement of Taronga's strategic importance and the growing recognition of tin as a critical mineral, essential for modern technology.

"The U.S. is reliant on imported tin, yet global supply remains tight and vulnerable to disruption. Australia is the only OECD tin-concentrate supplier, and with the largest undeveloped tin resource base in the OECD, First Tin is well placed to deliver secure and sustainable supply to major Western economies.

"With a completed Definitive Feasibility Study and permitting well advanced, Taronga is ready to become a significant, responsible supplier of this critical mineral. This indicative support from EXIM marks an important milestone as we progress funding discussions to bring this project into production."

Notes to Editors

First Tin PLC is an ethical, reliable, and sustainable tin production company led by a team of renowned tin specialists. The Company is focused on becoming a tin supplier in conflict-free, low political risk jurisdictions through the rapid development of high value, low capex tin assets in Germany and Australia, which have been de-risked significantly, with extensive work undertaken to date.

Tin is a critical metal, vital in any plan to decarbonise and electrify the world, yet Europe and North America have very little supply. Rising demand, together with shortages, is expected to lead tin to experience sustained deficit markets for the foreseeable future.

First Tin's goal is to use best-in-class environmental standards to bring two tin mines into production in three years, providing provenance of supply to support the current global clean energy and technological revolution.
