Endeavour Silver Corp. reported continued high-grade drill results from its 2021 exploration program at the Guanacevi Mine in Durango State, Mexico and the Bola?itos Mine in Guanajuato State, Mexico. Exploration drilling is ongoing at both operations and will continue in 2022. Abbreviations include: gpt: grams per tonne; Au: gold; Ag: silver; ETW: estimated true width; m: metre; HW: hanging wall. Silver equivalents are calculated at a ratio of 80:1 silver:gold. A quality control sampling program of reference standards, blanks and duplicates has been instituted to monitor the integrity of all assay results. All samples are split at the local field office and shipped to SGS Labs, where they are dried, crushed, split and 250 gram pulp samples are prepared for analysis. Gold is determined by fire assay with an atomic absorption finish and silver by aqua regia digestion with ICP finish, over-limits by fire assay and gravimetric finish.
