Vancouver, British Columbia – March 29, 2022 – Sierra Madre Gold and Silver Ltd. (TSXV: SM,
OTCQB: SMDRF) ("Sierra Madre" or the "Company") is pleased to announce additional results in
its ongoing trenching program at the La Tigra project, located in northern Nayarit, Mexico.
Highlights include 4.7 meters grading 5.64 g/t AuEq in LTZ010 and 4.73 g/t AuEq over 4.1
meters in LTZ011. The results for trenches 9, 10 and 11 are tabulated below.

or 15.3 19.4 4.1 4.69 3 4.73
Notes:
1. Intervals reported are Trench lengths with true width estimated to be 90% or greater
2. Length-weighted averages from uncut assays
3. *Gold silver ratio used to calculate AgEq is 75 g/t Ag to 1 g/t Au
Greg Liller, Chief Operating Officer states, “The trenches continue to deliver strong gold results
in the main structures and the broad zones of more moderate gold grades are very encouraging
for the development of a larger project.”
In addition, LTZ02 was extended to the east as previous sampling began in gold mineralization.
Additional moderate gold grades are present in the trench extension resulting in a combined
length of 37.7 meters grading 0.37 gold, 3 g/t silver for a AuEq grade of 0.38 g/t.
The following map shows the location of the trenches.
