VANCOUVER, BC / ACCESSWIRE / April 12, 2022 / Sierra Madre Gold and Silver Ltd. (TSXV:SM) (OTCQB:SMDRF) ("Sierra Madre" or the "Company") is pleased to announce the results from the first seven drill holes from the Phase 2 drilling program at its Tepic Silver/Gold Project in the State of Nayarit, Mexico.

Four of the holes are up-dip extensions from the previously defined historic resource area while three are strike extensions. All seven holes intersected a minimum of three metres of 100 g/t AgEq (silver equivalent grams per tonne) and will significantly add to the potential size of the upcoming NI 43:101 resource report. Hole TDH006 also intersected mineralization from a known vein that was drilled past a perceived fault that was incorrectly identified by a previous operator. This continuous mineralization increases the strike-length potential by multiple kilometres for the Dos Hornos 2 Vein. Dos Hornos 2 was a substantial vein system in the historic resource area.

Gregory K. Liller, Executive Chairman and Chief Operating Officer commented, "We are delighted with the results from the first seven diamond drill holes from our Phase 2 exploration program at our Tepic Silver/Gold Project. Having all drill holes intersect relatively shallow mineralization is a real plus for the project. This bodes extremely well for the upcoming NI 43:101 resource report. Holes 8-15 have now been completed and results will be released as assay results are received."

The results of the first seven holes are tabulated below:

1. Length-weighted averages from uncut assays
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/tAgEq cut Off

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.
