Executive Summary

Northisle Copper and Gold announced significant drilling results from its Red Dog deposit at the North Island Project on June 10, 2026.
The company identified a new, high-grade eastern mineralized trend extending beyond the 2025 PEA pit shell.
Key intercepts include 216.0m at 0.67% Cu Eq. (including 64.1m at 1.10% Cu Eq.), 163.4m at 0.86% Cu Eq., and 126.0m at 0.89% Cu Eq.
The results demonstrate broad, continuous mineralization at depth and validate the potential for resource expansion.
A total of 8,112 metres were completed across 31 holes in the 2025–early 2026 program, covering infill, metallurgical, geotechnical, and exploration drilling.
Management plans to drill an additional ~14,500 metres in the remainder of 2026 to further delineate the eastern trend and support the ongoing Pre-Feasibility Study (PFS).
The results will be incorporated into the integrated resource estimate and the PFS, which is targeted for completion in Q4 2026.

Material Impact

The drill results are consistent with the company's stated exploration strategy and PFS preparation timeline. They are not unexpected but rather a planned continuation of the district-scale exploration program.
The identification of a new high-grade eastern trend is geologically significant and reduces exploration risk, but it does not immediately alter the financial model or valuation until the PFS is completed and the resource is upgraded.
The news is incremental to the broader project narrative. It confirms the continuity of mineralization and supports the company's claim of a district-scale porphyry system, but it does not constitute a fundamental change to the project's economics or development timeline.
Given the company's recent $115 million financing and strong balance sheet, the market likely views this as expected progress rather than a surprise catalyst.

Company Overview

Northisle Copper and Gold is advancing the North Island Project, a >34,000-hectare copper-gold porphyry land package in northern Vancouver Island, British Columbia.
The project features multiple targets, including Red Dog, Northwest Expo, West Goodspeed, and Cougar.
The 2025 Preliminary Economic Assessment (PEA) outlined a staged development strategy with a $2.0 billion after-tax NPV (7% discount) and a 29% after-tax IRR.
The project is designed for low capital intensity, with Phase 1 targeting a payback period of approximately 1.9 years and a mine life of ~29 years.
Management is targeting a Pre-Feasibility Study (PFS) completion by late 2026, followed by an Integrated Project Delivery (IPD) filing.
