4 June 2025 – London, UK – Western Tethyan Resources Ltd. (“WTR” or “the Company”), a UK-based mineral exploration company, is pleased to announce several key developments in its ongoing regional growth strategy. These include the application for an extension of its exploration license over the Hertica Porphyry Project, submission of a new license application over the Slivova Gold Project in Kosovo, and continued evaluation of multiple new exploration opportunities in North Macedonia and Bulgaria.

Hertica License Extension – Focused Advancement of a Key Porphyry System

WTR has submitted an application for a new exploration license covering 29.99 km², extending its work over the Hertica Porphyry Project in eastern Kosovo. The Hertica license is set to expire on 14 July 2025. This application follows the expiration of the current 59.99 km² license, under which WTR has conducted extensive geological mapping, geochemical sampling, geophysical surveys, and drilling across a large porphyry system. The reduced area reflects a focused and strategic narrowing to the most prospective zones identified during early exploration. To date, the work on Hertica has been funded primarily through the Exploration Alliance Agreement with Newmont Corporation. (More on Hertica)

Slivova Gold Project – License Application to Secure Strategic Position Amid Regulatory Transition

WTR through the AVU Kosova (a Kosovan registered company owned 51% by WTR and 49% by Avrupa Minerals – TSX-V AVU) has also submitted a new exploration license application over the Slivova Gold Project area, covering 30.5 km², matching the surface area of the previously held license. This step follows delays in formal approval by the Independent Commission for Mines and Minerals (ICMM) regarding the transfer of control, reflecting WTR’s recently earned 51% interest in the project. The new application ensures continuity of tenure and provides a framework for resuming field activities once regulatory confirmation is complete. To date, the work on Slivova has been funded primarily via Ariana Resources Ltd. (More on Slivova)

Regional Expansion – Evaluating New Projects Across the Western Balkans

In line with its broader strategic vision, WTR is actively assessing multiple new exploration opportunities across the Western Balkans. The Company has submitted several license applications in North Macedonia and Bulgaria, targeting underexplored districts with strong geological potential for copper-gold and polymetallic mineralization. WTR expects that certain projects, if granted or acquired, may form part of the Exploration Alliance Agreement with Newmont Corporation.

Mentor Demi, Managing Director of Western Tethyan Resources stated that: “Extending our tenure at Hertica is a key step in our exploration strategy, and the Hertica Project remains a high-priority target in our portfolio. This license extension ensures we can continue building on our substantial exploration progress and begin targeting drill-ready zones within a refined project footprint.”

“The Slivova project is an exciting near-term opportunity for WTR. While we await regrant of our license, this application safeguards our interest and enables us to remain on track for exploration and potential development.”

“We are leveraging our deep regional expertise and a strong technical foundation to expand our footprint. Our goal is to establish a pipeline of high-quality projects across the Western Tethyan Belt, a region we believe holds tremendous long-term value.”
