Tonnages have been rounded to the nearest 1,000 tons. Average grades may not sum due to rounding. 2. Base case 42° average pit wall slope angle for open pit resources. 3. Open pit sulphide resources are reported at a 13.20 USD NSR cut-off. Open pit oxide resources are reported at a 23.10 USD revenue/ton cut-off 4. Underground resources are reported at a 58USDNSR cut-off below 4,159 m ASL 5. Metal prices used were 25.00 USD/Oz silver, 0.89USD/lb lead, and 1.00 USD/lb zinc. Lead and zinc do not contribute to revenue in the oxide zone. 6. Contributing 1 m assay composites were capped at 1,500 g/t Ag, 15% Pb, and 15% Zn. 7. Specific gravity is based on an interpolated inverse distance squared model. 8. Mineral resources that are not mineral reserves do not have demonstrated economic viability. The estimate of mineral resources may be materially affected by environmental permitting, legal, title, taxation, sociopolitical, marketing, or other relevant issues. TWP Sudamérica S.A. Av.
