Nord Precious plans fall drilling program at Castle

Executive Summary

• Independent geoscience firm Ronacher McKenzie Geoscience completed a comprehensive 3‑D model of the Castle East property, identifying 29 mineralized veins (up from five previously known).
• The new model reveals a stockwork vein system with multiple fault bends and dilational zones that explain historic high‑grade silver intercepts.
• Nord Precious Metals will commence a fall drilling program to test the newly modeled targets and advance toward an updated resource estimate.

Key Details

• Data Reviewed: >75,000 m of drill core, orientation, assay, alteration, lithology, structural data, ground/airborne geophysics, downhole EM, plus regional public datasets.
• Vein Inventory: 21 veins modeled in high‑density Area A; 8 veins in Area B – total 29 veins with varied orientations (N‑S, E‑W, NW‑SE).
• Grade Shells: Constructed using only assays >50 g/t Ag to focus on highest‑grade zones.
• Structural Insights: Multiple fault bends and jogs create dilational zones favorable for high‑grade mineralization; these structures underpin the exceptional grades previously reported (e.g., 6,476 g/t Ag over 3.09 m).
• Modeling Criteria: Utilized oriented core measurements, detailed vein descriptions/classifications, inter‑hole vein spacing, and assay values.
• Priority Drill Targets:
• Exploration of the underexplored lower contact of the Nipissing diabase (≈215 ha) with veins projected to extend 50–80 m beyond existing drill intercepts.
• Additional targets derived from the newly identified stockwork network and structural dilational zones.
• Future Work: Fall drilling campaign planned to test modeled veins/targets, refine structural model, and generate data for an updated resource estimate (building on the prior 30,000 m drill program).
• Qualified Person: Frank J. Basa, P.Eng., director and qualified person under NI 43‑101, approved all technical information.

Notable Quotes

“The identification of a stockwork vein system… fundamentally changes our understanding of the potential scale for Nord's Castle East property.” – Frank J. Basa, President & CEO

Materiality Assessment: Material – Positive (the discovery of a substantially larger vein network and planned drilling to substantiate resources represent material, forward‑looking information likely to influence investor perception).
