[{"type":"text","content":"Sierra Madre Samples 18.2 g/t Gold and 65.2 g/t Silver at Newly Acquired La Tigra, in Nayarit, MexicoVANCOUVER, BC / ACCESSWIRE / October 28, 2021 / Sierra Madre Gold and Silver Ltd. (TSXV:SM) (\"Sierra Madre\" or the \"Company\") is pleased to provide an update on its La Tigra Gold and Silver project located in the State of Nayarit, Mexico. La Tigra is located approximately 148 km north of Sierra Madre's Tepic project.Assays have been received for 319 reconnaissance samples with values ranging from <0.005 to 18.2 grams per tonne gold (\"g/t Au\"). The average gold grade of all samples received to date is 0.48 g/t Au with 32 samples greater than 1.0 g/t Au and 10 samples greater than 3.0 g/t Au. Silver values range from <0.5 to 65.2 g/t silver (\"Ag\") and average 3.99 g/t. Ag with 30 samples greater than 10 g/t Ag and 4 samples greater than 30 g/t Ag.Two structural systems have been identified that host gold and/or silver mineralization. A gold rich quartz-barite-hematite system which strikes to the northwest and dips 35 to 45 degrees to the southwest. The stacked nature of these structures is shown in the section below.AuEq is calculated using a 75:1 silver gold ratio.The second system is silver dominant with base metals which strikes to the northeast and dips 55 to 70 degrees to the southeast.Gregory K. Liller, Sierra Madre's Executive Chairman and COO commented, \"The recognition of stacked veins within this gold rich structural system adds to the properties potential. This means that the upcoming Phase 1 drillholes will have multiple targets in each hole, increasing the efficiency of every drilling dollar spent.\"Based on the results obtained thus far a trenching program is underway along with continuous channel sampling of road cuts where veining, stockworking and alteration is exposed. Data from the trenching program will be used to refine the Phase 1 drilling program which will start upon receipt of permits.Geo Digital Imagen de México SA de CV was contracted to provide satellite imagery, digital terrain models, and topographic maps. The project area was then divided into 27 blocks for detailed geologic mapping at a 1:2,000 scale. Mapping of the area is approximately 80% completed.Sierra Madre Gold and Silver Best PracticeSierra Madre is committed to best practice standards for all exploration and sampling act...
