VANCOUVER, BC / ACCESSWIRE / April 4, 2022 / Sierra Madre Gold and Silver Ltd. (TSXV:SM)(OTCQB:SMDRF) ("Sierra Madre" or the "Company") is pleased to announce commencement of its maiden drilling program at its La Tigra Gold Silver project, located in Nayarit, Mexico. The La Tigra project consists of seven Mining Concessions, totaling 357 hectares, covering the historical high-grade mines in the Districto Minero Del Tigre. Servico Geológico Mexicano (SGM), a department of the Mexican Federal Secretaria de Economia, reports the historic grade of material derived from the La Tigra mine between 1983 and 1991 was 10 g/t gold and 358 g/t silver. This is the first ever drill program undertaken within the district.

La Tigra drilling will focus primarily on areas defined by the ongoing trenching program.

Results of the trenching program previously released are tabulated below:

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 AuEq is 75 g/t Ag to 1 g/t Au

Greg Liller, Executive Chairman and COO of Sierra Madre states, "Drilling is underway on the first hole. The Phase I drilling program at La Tigra has been designed using the data we acquired from our extensive surface mapping, sampling and trenching programs. This work has defined a 3.5 km long structural corridor with stacked northwest striking structures. These stacked veins and breccias will allow some holes to test multiple targets giving us more value for our exploration expenditures. Drill targets will be methodically tested and, as new assay data is acquired and incorporated into the project database, additional drilling will be undertaken. Maiden drilling programs are always exciting, and this one even more so, as these will be the first ever holes drilled in the district".

The drilling contractor, Tecindyser S.A. de C.V., has mobilized one core rig to the project site. The core rig was moved from the Company's Tepic project; located 140kms away also in Nayarit, Mexico. The plan is to move the drilling equipment back and forth between the Tepic and La Tigra projects so as to ensure assay results are available before off set or step out drilling is begun. The company currently has 2 drill rigs in operation; one each at Tepic and La TIgra.

The Mexican federal environmental permitting agency, SEMARNAT; authorized the use of 30 drill pads within the La Tigra Project. Multiple exploration holes can be drilled and offset from each permitted pad. In addition, the Company entered into formal surface rights exploration agreements with Ejidal Santa Maria Picachos in January of 2022.
