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, British Columbia – 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:
1. Highlighted rows indicate the trench starts and/or ends in mineralization
2. Intervals reported are Trench lengths with true width estimated to be 70 - 90%
3. Length-weighted averages from uncut assays
4. Intervals reported at a 30 g/t AgEq * cutoff
5. *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.
Sierra Madre Gold and Silver Best Practice
Sierra Madre is committed to best practice standards for all exploration and sampling activities.
The Company’s exploration programs have been conducted following CIM Exploration Best
Practice Guidelines which are incorporated by reference in NI 43 -101. A nalytical quality
assurance and quality control procedures include the systematic insertion of blanks, standards
and duplicates into the sample strings. Samples are placed in sealed bags and shipped directly to
Bureau Veritas Lab located in Durango, Mexico for 30 gram gold fire assay and multi -element
analyses by acid digestion.
