VANCOUVER, BC / ACCESSWIRE / May 12, 2022 / Sierra Madre Gold and Silver Ltd. (TSXV:SM)(OTCQB:SMDRF) ("Sierra Madre" or the "Company") is pleased to provide an update on its La Tigra Gold/Silver Project (La Tigra") located in the State of Nayarit, Mexico. La Tigra is located approximately 148 km north of Sierra Madre's Tepic Project.

Assays have been received for 154 channel samples taken from Level 200 of the historic El Tigre mine. The samples ranged between of 0.011 grams per tonne gold ("g/t Au") and 239.0 g/t Au. Sample channel widths varied between 0.35 meters and 1.70 meters, averaging 0.92 meters. All samples contained detectable gold. The average grade of all the samples is 3.14 g/t Au with 65 samples greater than 0.5 g/t Au and 39 samples greater than 1.0 g/t Au. Silver values range from below the 0.5 g/t Ag detection limit to 76.0 g/t Ag.

Drilling:

Two drill rigs have been moved from the Company's Tepic Project to La Tigra. A third rig with greater depth capacity has been brought to site and will replace one of the smaller rigs. Geologic and surveying activities have focused on mapping and sampling the underground workings in the 200 level of the El Tigre mine, as well as opening and securing the 300 level for additional channel sampling to further enhance drill target definition.
