Canadian Silver Hunter Announces Assay Results

Executive Summary

• Canadian Silver Hunter released assay results from a trench‑sampling program on three polymetallic stockpile sites (ES1, EC1, BM1) in Michoacán, Mexico.
• Multiple samples showed significant grades of gold, silver, copper, lead and zinc, indicating the potential to unlock substantial metal value through re‑processing of historic waste rock.
• The company will conduct a volumetric survey, additional systematic sampling, and metallurgical testing to develop a NI 43‑101 compliant resource estimate and a preliminary economic assessment for stockpile re‑processing.

Key Details

• Sampling Program: Conducted 6–11 Dec 2025; 23 trench samples collected across ES1 (14 samples), EC1 (3 samples) and BM1 (6 samples).
• Assay Highlights (selected):
• BM1‑002: Au 7.33 g/t, Ag 17.30 g/t, Cu 0.503 %, Pb 0.172 %, Zn 0.058 %
• EC1‑001: Ag 718 g/t, Au 0.11 g/t, Cu 1.281 %, Pb 0.056 %, Zn 0.261 %
• ES1‑014 (duplicate): Au 0.40 g/t, Ag 270.15 g/t, Cu 1.274 %, Pb 0.094 %, Zn 0.076 %
• ES1‑009: Au 0.11 g/t, Ag 234.38 g/t, Cu 0.326 %, Pb 0.038 %, Zn 0.245 %
• Analytical Lab: Servicio Geologico Mexicano (SGM), accredited Q‑0401‑066/12; fire assay for Au, aqua regia digestion with ICP‑OES for Ag, Cu, Pb, Zn.
• QA/QC: Two duplicate samples included; all results within acceptable QA/QC limits.
• Historical Context: Stockpiles consist of waste rock from historic high‑grade hand‑cobbed mining (Spanish era) and modern underground/open‑pit operations; previously unprocessed material now targeted for re‑processing.
• Next Steps:
• Volumetric survey to estimate tonnage at each stockpile.
• Additional systematic sampling to refine average polymetallic grades.
• Composite sample collection for metallurgical testing.
• Development of NI 43‑101 compliant mineral resource estimate and preliminary economic assessment (PEA) on re‑processing viability.
• Management Quote: Jeff Hunter, President & CEO – “This initial phase… will continue to be the focus as we work towards defining a preliminary process flow sheet for the treatment of this material through a process plant.”

Notable Quotes

“This initial phase of the exploration, sampling, mineral characterization and metallurgical test‑work of the ES1, EC1 and BM1 stockpile material will continue to be the focus as we work towards defining a preliminary process flow sheet for the treatment of this material through a process plant.” – Jeff Hunter, President & CEO

Materiality Assessment: Material – Positive (the assay results provide materially positive information about the potential value of existing stockpiles and outline concrete next steps toward resource definition and economic assessment).
