Exploration Programs

SIERRA MADRE PROVIDES EXPLORATION UPDATE

Vancouver, British Columbia – April 21, 2021 – Sierra Madre Gold and Silver Ltd. (“ Sierra Madre” or

the “Company”) (TSXV:SM) is pleased to announce an update on its 100% owned Tepic Silver-Gold

Project (the “Project”) . The Tepic Silver Gold Project hosts low-sulfidation epithermal silver and gold

mineralization lying within the Sierra Madre Geologic Province. Significant expenditures in exploration

and engineering were completed by previous operators.

Tepic Gold-Silver Project

Sierra Madre’s Tepic Silver -Gold Project lies 22 kilometres southeast of the city of Tepic, Nayarit State,

Mexico. The Project has seen a significant amount o f previous exploration and drilling which is detailed

in a Technical Report titled Technical Report on the Tepic Property, dated March 29, 2021 and available

on SEDAR. The Company initiated exploration activities in late 2020.

Exploration and Property Development Team

Sierra Madre has hired Luis Saenz as Director of Exploration and Development. Luiz has 31 years of

experience and worked closely with the company’s COO Greg Liller on the exploration and development

of the Magistral Mine (part of McEwin Gold’s El Gallo Mine Complex), the exploration, development,

construction, and early production phases of both the open pit and underground mines at Ocampo (sold

to Frisco for $750 million) and the expansion project for the La Guitarra mine (sold to First Maje stic for

$125 million). Luis has extensive contacts throughout the Mexican mining industry and more recently was

Subdirector of Exploration and Special Projects for Minera Frisco.

Luis has put together a team of senior geologists for the Company with +90 years of exploration and

project development experience. They are backed up by a support group of computer literate junior

geologists with excellent field skills, along with field technicians and administrative personnel.

Comprehensive Project Mapping

The senior geologists have begun a phased project wide mapping program. This program began with

the core area which was the focus of previous drilling, as well as small scale historical mining activity.

Field work has now expanded to include mapping to the west and north and additionally on the

eastside of the Project. Preliminary indications are the hydrothermal system responsible for the silver

and gold mineralization is more extensive than previously known.

Topographic Map and Satellite Imagery

Real time Satellite Imagery was captured in the final weeks of November 2020 following the placement of

survey control points on the ground. The Orthophoto imagery and topography map s, which include

topographic contour lines with ± 30-centimeter accuracy, were delivered the end of December. These

detailed maps provide an invaluable toll for accurately locating and plotting previous drill holes, historical

mining works, and outcropping veins and mineralized structures which has already led to updated

interpretations and the identification of previously undocumented zones and targets.

Historic Data Compilation

Incorporation of historic data, including the majority of the 31,000 metres of drill core, into S ierra

Madre’s GIS data base began in January 2021. An inventory of the historic core has been completed

and a photographic library of all core is underway.

The core photos will be valuable in planning and executing the upcoming reverse circulation drilling

program.
