SIERRA MADRE DRILLING INTERSECTS 3.05 METRES GRADING 743 G/T AGEQ & 4.5 METRES

GRADING 402 G/T AGEQ AT THE TEPIC PROJECT, NARARIT, MEXICO

Vancouver, British Columbia – April 27, 2022 – Sierra Madre Gold and Silver Ltd. (TSXV: SM,

OTCQB: SMDRF) ("Sierra Madre" or the "Company") is pleased to announce the results of

additional drill holes from the Phase 2 drilling program at its Tepic Silver/Gold Project in the

State of Nayarit, Mexico. The results for holes TDH008 through TDH012 are tabulated below:

Area Hole From (m) To (m) Int(m) Ag g/t Au g/t AgEq g/t

Veta Tomas TDH008 112.5 119.15 6.65 210.5 1.06 290

Includes 114.0 115.5 1.5 524.0 2.47 709

Dos Hornos 2 TDH009 8.0 12.5 4.5 263.8 1.85 402

Includes 9.5 11.0 1.5 740.0 2.37 918

Veta Tomas TDH010 78.15 81.2 3.05 625.4 1.60 743

Astasis 2 TDH011 27.0 28.5 1.5 185.5 0.26 205

TDH012 33.0 34.5 1.5 110.0 0.23 127

1. Length-weighted averages from uncut assays

2. Intervals reported are hole lengths with true width estimated to be 90% or greater

3. *Gold silver ratio used to calculate AgEq is 75 g/t Ag to 1 g/t Au

4. 75 g/t AgEq external cut Off

To date all 12 holes for which assays have been received have intersected silver and gold

mineralization using a +75 g/t AgEq external cutoff. Ten of the twelve holes were designed to

test up dip or strike extensions of known structures outside of the volumes used in the

historical resource estimations. Two holes have tested new targets over 2 kilometers away

from the historic resource area.

Gregory K. Liller, Executive Chairman and Chief Operating Officer commented, “I am very

pleased that all of the holes drilled to date have returned positive results. I find Holes TDH010

and TDH011 to be very important. The Astasis structures are essentially blind targets covered

by very young basalts. A very small erosional window in a gully is the only natural exposure. I

find the fact that the first two holes hit +75 g/t AgEq intercepts to be highly encouraging.

Additional drilling at Astasis is currently being planned”

The maps below show the locations of the drill holes:

The Phase 2 drill program has been designed to test extensions of the previously defined

breccia/vein structures, test newly defined targets and infill the existing drill pattern in order to

facilitate the estimation of an updated NI43-101 compliant resource. The Tepic project is a

+2,600 hectare project where the previous operator completed 149 core holes totaling more

than 31,000 meters.
