VANCOUVER, BC / ACCESSWIRE / May 11, 2021 / Sierra Madre Gold and Silver Ltd. ("Sierra Madre" or the "Company") (TSXV:SM) is pleased to announce drilling has begun at its 2,600 hectare Tepic Silver Gold project located in the State of Nayarit, Mexico. The drilling contractor is Tornado Drilling S.A. de C.V with main offices in Hermosillo, Sonora. The Phase 1 drilling program is scheduled for 21 holes. The Company is currently permitted for a total of 67 drill holes.

Reverse circulation drilling methods are being employed as the previous operator experienced poor core recovery, especially within the mineralized zones of interest. Samples will be collected at 5-foot intervals for the entire hole. The contractor will use face sampling air hammers throughout the drill hole. The air pressure caused by the reverse circulation hammer bit face and center passage tube, create a vacuuming effect, forcing sample cuttings into the center passage of the dual walled pipe. This method of drilling can achieve near 100 % sample recovery with very little risk of contamination.

The targets for this drilling are mineralized structures located in the Central Area of the Tepic project. See the Sierra Madre press release dated May 4, 2021 for the location of the various project areas at Tepic:
