Sierra Madre Reports 9.2 metres Grading 543 g/t AgEq & 10.1 metres Grading 119 g/t AgEq at the Tepic Project, Nayarit, Mexico
VANCOUVER, October 19, 2021 - Sierra Madre Gold and Silver Ltd. (TSXV:SM) ("Sierra Madre" or the "Company") is pleased to announce the results of the first 11 trenches at its Tepic Silver Gold project located in the State of Nayarit, Mexico. The first phase of the trenching program has been increased to 5,000 meters, from 2,700 metres which was announced on June, 18 2021. Press Release Highlights of the results received thus far include TZ005 with 10.5 meters grading 91 g/t AgEq, TZ011 with 10.1 meters grading 119 g/t AgEq and TZ011A with 9.2 meters grading 543 g/t AgEq. Sierra Madre is currently sampling trench 33 and the following tabulates the results of the first 11 trenches.

Notes:
- Bolded rows indicate the trench starts and/or ends in mineralization
- Intervals reported are Trench lengths with true width estimated to be 70 - 90%
- Length-weighted averages from uncut assays
- Intervals reported at a 30 g/t AgEq * cutoff
- *Gold silver ratio used to calculate AgEq is 75 g/t Ag to 1 g/t Au
Luis Saenz Sierra Madres Director of Exploration and Development observes, "The widths of some of the mineralized trench intervals highlight the potential to develop bulk tonnage type deposits which may be amenable to near surface open cut mining. The fact that the trenches are returning silver and gold values outside of the previously mapped vein and breccia structures and revealing the presence of multiple secondary mineralized structures, gives us new targets and increases the potential of the Tepic project".
Trenches are excavated by hand or use road cut exposures where possible. Portable rock saws are used to cut continuous channels in order to produce a sample comparable to that obtained by core or reverse circulation drilling. Individual sample lengths range from 0.5 to 2.6 meters and are generally between 1 and 1.5 meters in length. The head of the trenches are either located with precision GPS equipment or surveyed from a previously establish control point. The azimuth and inclination of the trenches are then surveyed using compass and chain methods.
