Silver Tiger Metals Inc. has reported exploration results from the Northern Area of its 100% owned El Tigre Project in Sonora, Mexico. The results include high-grade intersections from the Caleigh and Protectora veins, as well as mineralisation linked to a newly identified Northern Stockwork Zone.
#High-grade Caleigh vein intersection
Drill hole ET-24-649 intersected 2.1 metres grading 7,715.1 g/t silver equivalent, or 102.87 g/t gold equivalent, between 39.9 and 42.0 metres. The interval contained 35.39 g/t gold and 5,061.1 g/t silver.
Within that interval, 0.53 metres graded 29,620.0 g/t silver equivalent, or 394.93 g/t gold equivalent, between 40.4 and 40.9 metres. This section contained 136.20 g/t gold and 19,405.0 g/t silver.
Silver Tiger said the result supports the presence of high-grade, near-surface mineralisation on the Caleigh vein.
#Protectora and Northern Stockwork results
Drill hole ET-24-643 returned 93 metres grading 70.1 g/t silver equivalent, or 0.93 g/t gold equivalent, from 16.9 to 109.9 metres. The interval consisted of 0.38 g/t gold and 41.2 g/t silver.
The hole included 0.60 metres grading 2,292.2 g/t silver equivalent, or 30.56 g/t gold equivalent, from 44.2 to 44.8 metres. That section contained 7.40 g/t gold and 1,737.0 g/t silver.
The company said the drilling confirmed high-grade mineralisation along the Protectora vein and a large, near-surface Stockwork Zone. The Northern Stockwork Zone is described as similar to the Stockwork Zone associated with the El Tigre heap leach project being built to the south.
A third hole, ET-24-638, returned 15.5 metres grading 101.9 g/t silver equivalent, or 1.36 g/t gold equivalent, from 20.7 to 37.8 metres. The interval contained 0.62 g/t gold and 55.2 g/t silver.
That result included 0.65 metres grading 1,457.0 g/t silver equivalent, or 19.4 g/t gold equivalent, from 22.5 to 23.15 metres. The included section contained 10.40 g/t gold and 667 g/t silver.
#Project location and exploration plans
The Northern Veins are located approximately 700 metres north of the area where Silver Tiger is building its heap leach mine. The company describes the Caleigh and Protectora veins as part of a broader northern vein system that also includes the Fundadora, Aguila, Benjamin and Benjamin Shale veins.
Silver Tiger said the Northern Veins remain open along strike and down dip. It also said additional drilling will be undertaken to infill the northern Resource area.
As part of its preparation for the 2026 drilling season, the company mapped and sampled historical workings in the Northern Area. Once sampling was completed, nearly every working was LiDAR scanned. The company said more than 400 drill-core samples were taken during this work, while 70% of the northern vein prospect area had been mapped by its geologists.
#El Tigre construction and geotechnical results
The announcement also included assay results from the 2025 geotechnical drilling campaign conducted inside the proposed El Tigre heap leach mine. One reported interval measured 1.0 metre grading 1,137.5 g/t silver equivalent, or 15.17 g/t gold equivalent, from 20.5 to 21.5 metres. It consisted of 15.10 g/t gold and 5 g/t silver.
President and Chief Executive Officer Glenn Jessome said the company remained focused on construction of the El Tigre heap leach mine and stated that it was on schedule for a first doré bar in December, 2027. Silver Tiger separately states that commissioning and first pour are targeted for December, 2027.
The company has entered into an Engineering Procurement and Construction Management Contract with Kappes, Cassidy & Associates and Kappes, Cassiday del Norte S de RL de CV. The Board of Directors has approved the construction decision for El Tigre.
#Reporting basis and risk disclosures
Silver equivalent ratios in the announcement are based on a silver to gold price ratio of 75:1 (Au:Ag). The company states that the reported widths are not true width.
Silver Tiger said the assay results passed its quality assurance and quality control protocols. Its cautionary statement notes that forward-looking information covers matters including future operating margins, production, processing and project plans. The company identifies risks related to exploration and development, mineral resource and reserve estimates, commodity price volatility, recovery rates and global economic conditions.
#Key Takeaways
