VANCOUVER, BC / ACCESSWIRE / June 18, 2021 / Sierra Madre Gold and Silver Ltd. ("Sierra Madre" or the "Company") (TSXV:SM) Sierra Madre Gold and Silver Ltd. is pleased to provide an update on activities at its Tepic Silver Gold project located in the State of Nayarit, Mexico.

Drilling Update
The Phase 1 reverse circulation drilling commenced on April 15th. The program is budgeted for 2,000 meters in 20 drill holes. Over 80% of the meterage has been drilled and the program should be completed next week. All results from the Phase 1 drill program will be released when assaying is completed.

A new drilling permit is being prepared for the upcoming Phase 2 drill program for an additional 100-200 holes.

Trenching Update
The previously announced 2,700 m Phase 1 trenching program has begun. 2,000 meters are budgeted for the central project area and the location of the first trenches are shown below.

The program has been designed to provide surface data on previously drilled vein and breccia structures for resource modelling purposes and to evaluate newly found structures for inclusion in the planned Phase 2 drilling campaign. In order to use the trench data in future resource estimations, portable rock saws are being used to cut the channel samples. This will ensure that the size and regularity of the samples is comparable to drill hole samples.

All trenches are being photo-documented.

New Vein Discovery - Eastern Area
In the eastern project area mapping and sampling in the area around the Taunas target continues. This work has defined a secondary antithetic vein structure, Taunas II, shown below, striking to the northeast.

The area has a great deal of colluvial and vegetative cover and a 400 meter trenching program has been budgeted for the eastern project area. Trenching will aid in planning a drilling program and allow the true widths of both Taunas structures to be assessed.

North Area
Mapping and sampling continue in the northern project area with an emphasis on prospecting arroyos and creek beds for signs of mineralization. The arroyo which contains the Anastis II showing is currently being trench as part of the initial 300 meter north area trenching program.
