Tier One Silver (TSXV:TSLV) - Extreme Silver Grades Drive Discovery Story

Interview with Peter Dembicki, President & CEO of Tier One Silver

Recording date: 23rd March 2026

Tier One Silver (TSXV:TSLV) is advancing an early-stage precious metals discovery in southern Peru that has delivered some of the highest-grade rock sampling results seen in the region. The company's 100%-owned Curibaya project has returned silver grades up to 300,000 grams per ton and gold grades approaching one kilogram, with over 80 samples exceeding one kilogram per ton silver distributed across a five-square-kilometer footprint.

Led by President and CEO Peter Dembicki, a former Canaccord Genuity investment adviser, the company benefits from world-class technical expertise. Christian Rios, formerly with Bear Creek Mining and integral to the Santana Corani discovery, serves as Senior Vice President of Exploration, while Antonio Arribas, former global head of geosciences for BHP and Newmont, provides additional technical guidance.

The property emerged from the 2021 spin-out of Auryn Resources and was consolidated through opportunistic acquisitions when base metal prices declined. Located in southern Peru's copper belt near the city of Tacna, the approximately 14,000-hectare property had never been systematically explored despite being surrounded by major global copper-silver producers.

Following an initial 5,000-meter reconnaissance drilling program, the company engaged independent consultants who identified a key insight: higher-elevation areas within the property should preserve a more intact precious metals system due to less erosion over geological time. The current 1,200-meter drilling program is testing this thesis in the Cambaya corridor, where rock samples have returned eight kilograms per ton silver and four grams per ton gold.

An unexpected discovery during initial drilling revealed indicators of a potential large porphyry copper system at depth, attracting attention from major mining companies seeking the next significant discovery in Peru's porphyry belt.

After operating through five years of challenging silver prices ranging from $17-22 per ounce, the company raised approximately $6.5 million in late 2025 as silver strengthened above $70. Management estimates requiring another 10,000 meters of drilling before resource definition, with six kilometers of identified vein corridors providing multiple targets. The company's strategy focuses entirely on discovery and resource definition rather than development, positioning for an eventual strategic transaction.
