Sierra Madre Samples 18.2 G/T GOLD and 65.2 G/T Silver at Newly Acquired LA Tigra, IN Nayarit, Mexico
SIERRA MADRE SAMPLES 18.2 G/T GOLD AND 65.2 G/T SILVER AT NEWLY ACQUIRED LA
TIGRA, IN NAYARIT, MEXICO
Vancouver, British Columbia – 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.
