Tinka Signs Agreement with Key Community at Ayawilca

• Tinka Resources Limited has executed a three-year agreement with the San Pedro de Pillao community covering 170 hectares overlying the Colquipucro deposit, a high-grade near-surface silver zone within the Ayawilca project in Peru.
• The agreement establishes a framework for collaborative exploration, technical studies, and local employment, with provisions for potential community investment opportunities.
• Management confirmed the Preliminary Economic Assessment (PEA) update is progressing on schedule. The study evaluates a staged development strategy starting with an open-pit operation at Colquipucro, followed by an underground mine at Ayawilca. Results are expected by early Q1 2027.
• This follows the October 2026 announcement where the company initiated the PEA update and a 5,000-metre drilling program, noting that community agreements were in final stages with expectations to close by Q3 2026.

• The community agreement removes a critical social license prerequisite for the Colquipucro deposit, which is now the proposed first phase of the staged development strategy. Execution aligns with management's prior guidance, demonstrating operational discipline and de-risking the PEA timeline.
• The news does not introduce new economic parameters, price assumptions, or resource estimates. It is a necessary administrative and social milestone rather than a valuation catalyst.
• Given the market's prior awareness of the PEA update and drilling plans, this execution is incremental. It supports the thesis but does not materially alter the risk/reward profile ahead of the actual PEA results.

• Tinka Resources Limited (TSXV: TK, OTCQX: TKRFF) is an exploration-stage mining company focused on critical metals in Peru and Saudi Arabia.
• Flagship Project: Ayawilca (Peru) is an undeveloped zinc-silver-tin deposit. Indicated resources total 28.3 Mt at 5.8% Zn and 16 g/t Ag. The project also hosts a separate tin zone and a high-grade silver zone.
• Colquipucro (Peru): A near-surface silver oxide deposit located ~2 km north of Ayawilca. Historical resources indicate 14.3 Moz Ag (Indicated) at 60 g/t Ag. The deposit is amenable to open-pit leaching.
• Silvia NW (Peru): A copper-gold skarn and porphyry target. Maiden drilling in 2025 intersected narrow Cu-Au zones, with geophysical surveys identifying deeper conductive anomalies.
• Huwaymidan (Saudi Arabia): A district-scale orogenic gold target. Tinka holds a 5% carried interest, fully funded by a local partner through mid-2027.
