TINKA ANNOUNCES COMMENCEMENT OF A STRATEGIC REVIEW

Further to the news release on Jan. 2, 2025, Tinka Resources Ltd. will not proceed with additional closings of its previously announced non-brokered private placement.

The company also announces that it has initiated a strategic review process with the assistance of a financial adviser to identify, assess and evaluate a broad range of potential strategic alternatives for the company with the view of maximizing shareholder value. A range of strategic and financing alternatives will be reviewed and considered.

Dr. Graham Carman, Tinka's president and chief executive officer, stated: "The company has deferred its planned drilling activities at Ayawilca whilst we carry out this important strategic review. Ayawilca is an attractive project considering the grade and scale of the mineral resource and its strong economics based on the 2024 Ayawilca preliminary economic assessment. We believe that the strategic review process will ultimately lead to a favourable outcome for all shareholders and stakeholders."

The company has not set a timetable for this process, nor has it made any decisions related to strategic alternatives at this time, and there can be no assurance that the exploration of strategic alternatives will result in any transaction. The company does not plan to provide updates on the status of the strategic review process until it determines that further disclosure is necessary or appropriate.
