SIERRA MADRE DRILLING INTERSECTS 6.35 METRES GRADING 424 G/T AGEQ & 6.05 METRES

GRADING 470 G/T AGEQ IN DRILL HOLE 14 AT TEPIC PROJECT, NAYARIT, MEXICO

VANCOUVER, BC / ACCESSWIRE / May 5, 2022 / Sierra Madre Gold and Silver Ltd. (TSX-

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

of the last four drill holes from the first round of exploration drilling at its Tepic Silver/Gold

Project in the State of Nayarit, Mexico.

Highlights include 3.85 meters grading 656 g/t AgEq and 2.30 meters grading 1,070 g/t AgEq,

both in hole TDH014.

The results for holes TDH013 to TDH016 are tabulated below:

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

Gregory K. Liller, Executive Chairman and Chief Operating Officer commented, “I continue to be

very pleased with the results of the first exploration holes we have completed at Tepic. These

holes were designed to test areas adjacent to and outside of the areas that were volumetrically

included in historic resource estimations. Two things stand out to me; 1) all holes drilled thus

far had +75 g/t silver intersections and 2) the weighted average grade of these intersections is

301 g/t AgEq. This average grade is better than previous drilling in the same structures and

may reflect improved core recovery. All this bodes well for the project’s expansion potential

and I am excited to start the next go around of drilling at Tepic.”

As planned, both drill rigs have now been moved to the company’s La Tigra gold silver project,

also located in Nayarit, where the maiden drilling program is underway. The data from the

Tepic drill holes is being incorporated into the project’s 3-D database and model to plan the

continuation of the Phase 2 drilling at Tepic. Drill pads have already been constructed on the

Taunas targets to drill the first test holes within the newly discovered area on the eastern

portion of the project.

The following tabulates the drilling completed thus far in the Phase 2 drilling program at Tepic:

The weighted average grade of the above intercepts, excluding the “Includes” intervals, is 215.0

g/t Ag, 1.14 g/t Au and 301 g/t AgEq. The average width is 3.66 meters. Excluding intercepts

less than 1.8 meters the weighted average is 222.3 g/t Ag, 1.14 g/t Au and 307 g/t AgEq. The

average width increases to 4.80 meters.

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.
