SIERRA MADRE REPORTS 12 METRES GRADING 2.91 G/T AUEQ; INCLUDING 4.5 METRES GRADING 7.05 G/T
AUEQ AT LA TIGRA PROJECT, NAYARIT, MEXICO
Vancouver, British Columbia – February 15, 2022 – Sierra Madre Gold and Silver Ltd. (TSXV: SM, OTCQB:
SMDRF) ("Sierra Madre" or the "Company") is pleased to announce additional results from trenching and a
project update at its La Tigra project located in the State of Nayarit, Mexico. Trench intercepts are located
northwest of the previous announced trenches (see News Release dated Nov. 16, 2021) and are summarized
in the table below.
La Tigra Trench Intervals
Structure Trench From To Int (m) Au g/t Ag g/t AuEq g/t
Zapolito LTZ06 9 13.9 4.9 0.46 3 0.49
El Verde LTZ07 3.8 14.8 11.0 1.03 1 1.05
includes 9.8 11.8 2.0 4.13 2 4.15
El Verde LTZ08 4.5 16.5 12.0 2.85 5 2.91
Includes 12 16.5 4.5 6.94 8 7.05
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
Gregory K Liller, Sierra Madre’s COO states, “I am very pleased to see the continued success of the La Tigra
trenching program. These three trenches, together with the previously released trenching results, confirm our
view that the Districo del Tigre has significant gold and silver potential.”
The trench locations are shown in the following map.
Trenching was conducted using picks and shovels to expose bedrock with continuous channels then cut with a
portable rock saw and samples removed using hammers and chisels.
La Tigra Project Update
Luis Saenz, Director of Exploration & Development states “We have gained safe access to the 100 and 200
levels of the historic El Tigre mine. Initial underground mapping indicates the structural fabric of the area is
more complex, containing both primary and antithetic structures which host quartz veins and breccias along
with a surrounding quartz stockworks. It has been my experience in other gold silver districts in Mexico that
this type of structural pattern has the potential to be economically very significant “
Continued district-wide surface mapping, sampling and trenching has delineated a northwest trending
structural corridor 3 km in length hosting multiple northwest striking veins and breccia zones along with
crosscutting northeast structures
The underground workings of the historic El Tigre mine have now been secured and access has been gained to
the 100 and 200 levels. Mapping and surveying are underway and will be used to update and improve the 3D
model for the mineralized structures in the El Tigre South Area shown in the map and cross section below.
Work thus far indicates historic mining focused on ore found between surface and the upper 100 level.
Mapping on the 200 level has shown workings were driven on both the main El Tigre vein and north trending
antithetic structures. These antithetic veins consist of a second set of mineralized structures which crosscut
the main mineralized trends. Antithetic structures have been found to be important hosts for ore mined at
Ocampo, El Cubo, La Guitarra and other mines in Mexico.
All of this valuable information is going into 3-D modeling and the planning of the upcoming drilling campaign
at La Tigra.
