Sierra Madre Drilling Intersects 32 Metres of 1.05 G/T AuEq During Maiden Drilling Program at the La Tigra Project, Nayarit, Mexico
VANCOUVER, May 24, 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 three holes of its maiden drilling program at the La Tigra Gold/Silver Project in the State of Nayarit, Mexico.
The drill intersections are tabulated below:
| Target | Hole | From (m) | To (m) | Length (m) | Au g/t | Ag g/t | AuEq g/t* |
| El Camino | LTDH001 | 0.00 | 9.00 | 9.00 | 0.46 | 9.2 | 0.58 |
| Includes | 0.00 | 4.50 | 4.50 | 0.68 | 18.3 | 0.92 | |
| and | 44.40 | 51.00 | 6.60 | 0.49 | 6.1 | 0.58 | |
| El Tigre North | LTDH002 | 25.40 | 30.50 | 5.10 | 2.21 | 23.7 | 2.52 |
| Includes | 28.20 | 30.50 | 2.30 | 3.52 | 34.7 | 3.99 | |
| El Tigre Mine | LTDH003 | 10.00 | 42.00 | 32.00 | 1.00 | 3.8 | 1.05 |
| Includes | 11.00 | 15.00 | 4.00 | 3.03 | 1.0 | 3.04 | |
| and | 27.35 | 31.80 | 4.45 | 2.72 | 7.2 | 2.82 | |
| or | 29.05 | 31.30 | 2.25 | 4.17 | 10.0 | 4.30 |
- Length-weighted averages from uncut assays
- *Gold silver ratio used to calculate AuEq is 1 g/t Au to 75 g/t Ag
- Length is calculated using a 0.15 AuEq external cut off
Greg Liller, the Company's COO observes "These are the first holes drilled in the Districo del Tigre and thus far we have hit encouraging shallow mineralization in all of them. I am particularly impressed with Hole 3, intersecting 32 metres of 1.0 g/t gold, as we had estimated the overall El Tigre mine zone to be somewhat narrower, in the range 10 to 12 metres. Holes 4 and 5 are currently away for assay and holes 6 and 7 are currently being drilled."
The Phase I drilling program at La Tigra has been designed using the data acquired from 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. Drill targets will be methodically tested and, as new assay data is acquired and incorporated into the Project database, additional drilling will be undertaken
The structures at La Tigra dip at 40? to 45? and holes 1 and 2 were drilled at -45? and hole 3, -53?. As such the true width of the intersections are approximately +90% of the intersected length.
The following map shows the location of the holes.
Sabra Concession
Due to the positive results of exploration activities, the Company is pleased to announce that it has filed for an additional mining concession covering 1,653 hectares. The area covered by the Sabra concession application lies to the west of the current La Tigra Project area as shown in the adjacent map.
This application significantly expands the footprint of the La Tigra Gold/Silver Project. A district-scale mapping and sampling program will be undertaken to locate prospective mineralized outcrops. Upon issuance of the concession title a trenching program followed by drilling will be initiated on any targets defined by this exploration work.
