- Estimates by First Majestic reviewed by PAH. Estimates based on Minimum Mining Width >2.00m. No mine recovery included.
- Silver equivalent based on sales. Prices used for evaluation: Ag - $12/oz; Au - $708/oz; Pb - $0.75/lb; Zn - $0.75/lb.
- Oxides Ag equivalent includes gold credit based on sales. Au Credit = 6 g/tonne Ag.
- Sulphides Ag equivalent includes Pb credit = 47 g/tonne Ag. Zinc is considered at 70% met. Recovery = 30 g/tonne Ag.
- Cut-off grade estimated as 184 g/tonne Ag net of Au credit in oxide ores; and 246 g/tonne Ag net of Pb credit in sulphide ores. Zinc not considered in COG estimates.
- Rounded figures.

- Cut Off Grade (COG) estimated as 250 g/tonne Ag only; and 228g/tonne Ag eqv net of Pb credit.
- Estimated Reserves are exclusive of Resources.
- Silver equivalent includes Pb credit, at prices US$12.00/oz-Ag, US$0.75/lb-Pb. Pb credit=22 g/tonne-Ag.
- Mining dilution is included at over 2.00m width. Estimates do not include mining recovery.
- Zinc is not recovered.
- Dump stockpile is considered as Measured Resource because the average grade is below COG -- 203 g/tonne Ag only and 186 g/tonne Ag eqv however with pre-screening may be processed.
- La Morena sulphide deposit requires additional metallurgical test work to prove its economic recovery. La Encantada mill does not have an operating zinc circuit at this time.
- Tailings are included within the Indicated Resources due to required additional test work and grade below Cut-off grade - 111 g/tonne Ag.
- Rounded figures
