Notes: All numbers are rounded
- Conforms to NI 43-101, Companion Policy 43-101CP, and the Canadian Institution of Mining, Metallurgy and Petroleum (“CIM”) Definition Standards on Mineral Resources and Mineral Reserves. Inferred Resources have been estimated from geological evidence and limited sampling and must be treated with a lower level of confidence than Measured and Indicated Resources.
- AgEq based on 75 (Ag):1 (Au), calculated using long-term silver and gold prices of U.S.$17 per ounce silver and U.S.$1,225 per ounce gold with average metallurgical recoveries of 90% silver and 95% gold.
- Bulk density has been applied to all materials as 2.55 tonnes per cubic metres.
- Vein resource is reported using a 150 gpt AgEq cut-off grade and minimum 0.5 m true width, Babicanora Norte, Babicanora Sur, Babicanora FW and Babicanora HW veins have been modelled to a minimum undiluted thickness of 0.5 m, Babicanora Main has been modelled to a minimum undiluted thickness of 1.5m, and surface stockpile (historic dumps) resource is reported using a 100 gpt AgEq cut-off.
- Babicanora Area includes the Babicanora, Babicanora Footwall, Babicanora Hangingwall, Babicanora Norte, Babi Sur and Granaditas veins.
- Las Chispas Area includes the Las Chispas, Giovanni (including La Blanquita), William Tell, Luigi, Giovanni Mini Veins and Historical Dumps. Inferred Resources for the Las Chispas Area remains unchanged from September 2018.
- There are no known legal, political, environmental, or other risks that could materially affect the potential development of the mineral resources.
