Silver Tiger Intersects 1.0 Metre of 12,851.5 G/T Silver Equivalent Within 16.0 Metres of 875.6 G/T Silver Equivalent in the Tigre Vein and Keel Zone
HALIFAX, NS / ACCESSWIRE / May 22, 2024 / Silver Tiger Metals Inc. (TSXV:SLVR)(OTCQX:SLVTF) ("Silver Tiger" or the "Company") is pleased to provide an update on the first 95 drill holes for the Company's ongoing Pre-Feasibility Study ("PFS") drilling program on the Stockwork deposit on its El Tigre Project in Sonora, Mexico. These new results are highlighting the high-grade mineralization beneath the floor of the 2023 PEA Open Pit in the Keel Zone and expansion of the PEA Starter Pit to the north.
Drill hole ET-24-568 cut 16.0 metres grading 875.6 g/t silver equivalent or 11.67 g/t gold equivalent from 155.0 to 171.0 metres, consisting of 409.9 g/t silver and 6.21 g/t gold and INCLUDING 1.0 metres grading 12,851.5 g/t silver equivalent or 171.35 g/t gold equivalent from 161.0 to 162.0 metres consisting of 6,034.0 g/t silver and 90.90 g/t gold and in the Keel Zone (Figures 1 & 2). The hole passed through the El Tigre vein located some 15m beneath the floor of the PEA Open Pit and is referred to as the Keel Zone.

New intersections through the Stockwork deposit, comprised of the Footwall, Hanging Wall and high-grade Keel Zones, are highlighted below, shown on Figure 3 and listed in Table 1.
- Drill hole ET-24-570: 59.3 metres grading 1.92 g/t gold equivalent or 144.1 g/t silver equivalent from 100.3 to 159.6 metres, consisting of 1.63 g/t gold and 21.8 g/t silver AND 9.5 metres grading 1.32 g/t gold equivalent or 99.2 g/t silver equivalent from 173.5 to 183.0 metres consisting of 1.32 g/t gold and 0.5 g/t silver. These intersections are located approximately 150 metres past the northern end of the 2023 PEA Starter Pit as shown in Figure 3.
- Drill hole ET-23-563: 45.0 metres grading 1.17 g/t gold equivalent or 87.6 g/t silver equivalent from 4.0 to 49.0 metres, consisting of 0.70 g/t gold and 35.0 g/t silver INCLUDING 15.0 metres grading 2.20 g/t gold equivalent or 164.7 g/t silver equivalent from 11.0 to 26.0 metres consisting of 1.01 g/t gold and 89.0 g/t silver gold in both the Hanging Wall and Footwall Zones.
- Drill hole ET-23-552: 35.5 metres grading 0.92 g/t gold equivalent or 68.7 g/t silver equivalent from 107.0 to 142.5 metres, consisting of 0.83 g/t gold and 6.2 g/t silver INCLUDING 7.0 metres grading 1.68 g/t gold equivalent or 126.3 g/t silver equivalent from 135.5 to 142.5 metres consisting of 1.66 g/t gold and 1.9 g/t silver in the Hanging Wall Zone.
Silver Tiger's CEO, Glenn Jessome, stated, "As we continue receiving promising assay results, it is apparent that the developing "Starter Pit" and "Keel Zone" show excellent grade and continuity." Mr. Jessome further stated, "The results may increase the updated MRE associated with the PFS-level study which we expect to deliver by September 2024, which will also further de-risk the project." Mr. Jessome continued, "We contemplate being able to make a build decision based on our upcoming PFS."
Silver Tiger has completed 24,500 metres of a 25,000 metre drilling program focused on expanding the Mineral Resource, up-grading the classification, completing metallurgical testwork and geotechnical studies as it progresses from an exploration to a development project. The value-added PFS progress is on schedule for publication in H2-2024.

Highlights from the on-going Pre-Feasibility Study Drilling Program include the following:
- Expanding known mineralization by 10 to 15%, to the footwall and hanging wall zones, as well as the higher-grade ‘Keel' at PEA pit bottom associated with the El Tigre and SK Veins;
- Converting first two to three years of mineralized material in the potential ‘Starter Stockwork Zone' from Indicated Mineral Resource to Measured;
- Converting a significant portion of the 2 km strike length ‘ultimate' PEA pit-constrained Inferred Mineral Resource to Indicated;
- Completion of enhanced PFS Metallurgical Drilling, with samples underway comminution and leach testing; and
- Completion of enhanced PFS Geotechnical Drilling, with samples undergoing testing.
Mineral Resource Drilling
P&E Mining Consultants Inc. ("P&E") of Brampton, Ontario completed the initial MRE in 2017. On Oct 27, 2023, P&E released an updated El Tigre Project NI 43-101 and NI 43-01 F1 compliant MRE technical report titled "Technical Report and Updated Mineral Resource Estimate of the El Tigre Silver-Gold Project, Sonora, Mexico" authored by William Stone, Ph.D., P.Geo.,Yungang Wu, P.Geo., Fred H. Brown, P.Geo., Jarita Barry, P.Geo., David Burga, P.Geo., D. Grant Feasby, P.Eng., Eugene Puritch, P.Eng., FEC, CET and David Salari, P.Eng. The MRE has a pit-constrained Indicated Mineral Resource totaling 43.0 million tonnes containing 818 thousand ounces AuEq grading 0.59 g/t AuEq; and a pit-constrained Inferred Mineral Resource of 11.5 million tonnes containing 267 thousand ounces AuEq grading 0.72 g/t AuEq (see update MRE press release dated September 12th 2023).
PEA-level bench optimization of the pit-constrained Mineral Resource highlighted the higher-grade (~0.80 gpt AuEq), low strip ratio (~0.3) potential Starter Stockwork Zone which contains 5.7 million tonnes of mineralized material (see PEA press release dated November 1st, 2023). Recommendations of the PEA-level study included increasing Mineral Resource confidence in potential ‘Starter Stockwork Zone' and additional exploratory drilling to target the 1) Footwall, 2) Hanging Wall and 3) ‘Keel' areas of the Stockwork Zone. P&E were again retained to lead the current El Tigre PFS-level study with 24,500 metres of the program completed as of May 15, 2024 . Complete and final assay results are listed in Table 1.
Below, highlighted intersections are enumerated with reference to the three (3) zones targeted (Figure 2):
- Drill hole ET-23-563: Confirms location and grade of the Hanging Wall Zone, and downhole, the Footwall Zone, and high-grade SK vein;
- Drill hole ET-23-552: Confirms location and grade of the Hanging Wall Zone, and downhole, expands the Footwall Zone 25m to the east over 2023 MRE;
- Drill hole ET-24-568: Expands depth and strike of Keel Zone over the 2023 MRE; and
- Drill hole ET-24-570: Confirms location and grade of the Hanging Wall Zone associated with El Tigre Vein.
