² The preliminary economic assessment (“PEA”) is preliminary in nature. It includes Inferred Mineral Resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as Mineral Reserves, and there is no certainty that the PEA will be realized. Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability. The PEA is based upon the Mineral Resource estimates for the Miraflores and Tesorito deposits with an effective date of July 31, 2025, and upon the assumptions, parameters and qualifications set out in the Technical Report. The Company has not completed a current pre-feasibility study or feasibility study on the project; studies completed by prior operators are treated as historical and not as current. Accordingly, the PEA does not affect the results of any current pre-feasibility or feasibility study.
³ Historical Inferred Mineral Resource: 20.2 Mt at 0.71 g/t Au (459,000 oz Au), reported at a 0.5 g/t Au cut-off grade.Source and date: Prepared by Resource Development Associates Inc. with an effective date of February 25, 2020, in accordance with the JORC Code (2012), and reported by Los Cerros Limited, a prior operator of the property; Relevance and reliability: The Company considers the historical estimate relevant because it indicates the potential presence and scale of mineralization at Dos Quebradas. While reportedly prepared in accordance with the JORC Code (2012), consistency with current standards is not assured. Tiger has not independently verified the underlying data and the estimate should not be relied upon; Key assumptions: parameters and methods. Based upon 19 historical diamond drillholes totalling 8,824 m at approximately 25 m section spacing, defining mineralization over approximately 400 m by 300 m from surface to approximately 550 m depth, hosted in diorite porphyry and intrusive breccias. A cut-off grade of 0.5 g/t Au was applied; Categories: The estimate uses the Inferred Mineral Resource category under the JORC Code (2012), substantively equivalent to the Inferred category in the CIM Definition Standards incorporated by reference into NI 43-101; More recent information: Tiger completed an initial three-hole diamond drill program at Dos Quebradas in 2026 totalling 1,274.65 m, disclosed in the Company’s news releases. No current Mineral Resource estimate has been prepared for Dos Quebradas; Work required to upgrade or verify: Relogging and resampling of historical core, database validation, check surveys, additional infill and confirmation drilling, and updated geological modelling and resource estimation in accordance with NI 43-101 and CIM guidelines; A qualified person has not done sufficient work to classify the historical estimate as current Mineral Resources or Mineral Reserves, and the Company is not treating the historical estimate as current Mineral Resources or Mineral Reserves.
⁴ Mineral Resource estimates have an effective date of July 31, 2025 and are reported in the Technical Report. Mineral Resources are reported by category. Inferred Mineral Resources are not added to Measured and Indicated Mineral Resources. Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability. There is no certainty that any part of an Inferred Mineral Resource will be converted to an Indicated or Measured Mineral Resource. No Mineral Reserves have been estimated on the Quinchía Gold Projectt
* Readers are cautioned that this assessment is preliminary in nature. It includes Inferred Mineral Resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as Mineral Reserves, and there is no certainty that this preliminary economic assessment will be realized. Life of mine (LOM) cash costs consists of mining costs, processing costs, mine site G&A, refining charges, and royalties. AISC includes cash costs plus sustaining capital, closure cost, and salvage value . See cautionary note on non-IFRS measures. Silver price fixed at US$29.51/oz Ag in both cases.
