Sierra Madre Gold and Silver Ltd. (TSXV: SM, OTCQX: SMDRF) ("Sierra Madre" or the "Company") - https://www.commodity-tv.com/ondemand/companies/profil/sierra-madre-gold-silver/ - is pleased to provide an update on its exploration activities at the 100% owned past-producing La Guitarra Silver-Gold Mine Complex (“La Guitarra”) in Estado de Mexico, Mexico, 130 km southwest of Mexico City.
Beginning in February of this year, the company started a 2,000-scale geologic mapping program, first in the eastern portion of the Temascaltepec mining district and then progressing to the west side. This mapping program is the first-ever project-wide undertaking. It provides additional data for understanding the structural controls on the vein-hosted silver and gold mineralization.
Gregory K. Liller, Executive Chairman and Chief Operating Officer commented, “Since acquiring the La Guitarra property in March 2023, we have completed the first-ever district-wide mapping exercise of the Temascaltepec mining district. The data will provide valuable information as we work on interpreting the controls on mineralization, advance our understanding of project-scale systems and plan future drill programs in the Eastern and Western districts.”
The company's mining concessions cover the entire Temascaltepec mining district and contain numerous Spanish Colonial, 19th, and early 20th-century mines.
District-Scale Mapping by Sierra Madre
To date, surface mapping has delineated nearly 53 km of mineralized quartz veins, breccias, and stockwork zones.Mapping in the Eastern district has delineated over 37.9 km of veining. The dominant strike direction of veining is to the northwest, accompanied by a second set of veins, known as antithetic structures, striking more easterly. Both groups of veins host gold and silver mineralization, with hundreds of old shafts, cross cuts, adits, and prospect pits having been located. Host rocks for the veins are metasediments and andesites. Approximately one-half of the area mapped thus far is covered by recent basalt flows, with the veins exposed in erosional windows (see Figure 1 below).
Mapping has been completed over a significant portion of the West district. Thus far, over 15 km of veins have been located at the surface. While the principal vein systems, Guitarra, Coloso, and Nazareno, have been exploited, the vein swarm north of Guitarra has yet to be drill tested despite having numerous old shafts, adits, and prospect pits (see Figure 2 below).
History of Temascaltepec District
The Temascaltepec district was one of the six most important silver districts in Mexico (New Spain) during the 1600s and 1700s, as evidenced by the Spanish crown appointing a special overseer to monitor activities in the district.
Mines, backed by European and American capital, were in operation during the late 1800's and early 1900's. Allan Nordstrom, in 1938, reported that the Rincon mine, in the easternmost part of the district, produced 281,642 tonnes at an average grade of 6.7 g/t gold and 860 g/t silver between 1926 and 1937. Vein width was between 2 to 5 meters.
Production between 1993 and 2018 came from the Guitarra, Coloso, and Nazareno mines, the focus of the company's production restart activities, with only limited exploration work completed outside of these areas. Previous operators LuisMin and Genco Resources drilled 76 drill holes in the East district, focusing primarily on the Santa Ana vein system. Drill results sufficiently encouraged Genco to start a production ramp in the Mina de Agua area. While First Majestic did no drilling, they followed up activities in the area, securing surface rights, completing an Environmental Impact Statement (MIA), and permitting a production center on the Santa Ana, Cascaras, and associated veins.
Next Steps
A surface and underground sampling program will commence as soon as the rainy season is over. The results of this program will provide information on the most favorable structural settings for silver and gold deposition. Results from this work will be used to plan exploration drilling programs in the East and West districts.
Extension of Subscription Receipts
Sierra Madre announces that, further to the Company’s news release dated May 31, 2023 (the “May 31 News Release”), the Company has amended the terms of all 5,123,092 subscription receipts (each, a “Subscription Receipt”) in order to extend the Escrow Release Conditions and Termination (as both terms are defined in the May 31 News Release) for an additional 30-day period.

About Sierra Madre
Sierra Madre Gold & Silver (TSX.V: SM, OTCQX: SMDRF) is a precious metals development and exploration company, focused on evaluating the potential of restarting the La Guitarra Mine in the Temascaltepec mining district, Mexico, and the exploration and development of its Tepic and La Tigra properties in Nayarit, Mexico. The La Guitarra Mine is a permitted, past-producing underground mine which includes a 500 t/d processing facility that operated until mid-2018.
The +2,600 ha Tepic Project hosts low-sulphidation epithermal gold and silver mineralization with an existing historic resource. La Tigra, located 148 km north of Tepic, has been mined historically; Sierra Madre´s maiden 2022 drill program at the site intercepted shallow mineralization.
Sierra Madre´s management has played key roles for managing exploration and development of more than 22Moz gold and 600Moz silver in combined reserves and resources. Sierra Madre´s team of professionals has collectively raised over $1B for mining companies.
