1844 Resources Launches 2026 Exploration

Program at the SV2 Copper System, Gaspé

Peninsula, Québec

Saskatoon, Saskatchewan--(Newsfile Corp. - May 21, 2026) -

1844 Resources Inc. (TSXV: EFF)

("1844" or the "Company") is pleased to outline its 2026 summer exploration strategy for the Company's

flagship SV2 Copper Project located in the Gaspé Peninsula, Québec, highlighting a targeted drill

program designed to validate known mineralization while advancing the Company's evolving district-

scale copper exploration model.

The 2026 program represents a significant evolution in the Company's technical approach, integrating

historical drilling data, geological reinterpretation, and recent geophysical work to refine priority

exploration targets across the SV2 project area.

2026 Summer Strategy

Technical Basis

The Company's exploration framework is built on a disciplined technical foundation, including:

Validation of historical exploration results and mineralized intercepts

Integration of historical drilling data with recent airborne geophysical datasets

Systematic reinterpretation of historical core logs and geological models

Development of conceptual deep exploration targets associated with intrusive-related copper

mineralization

Detailed Geological Mapping

As part of the 2026 program, the Company will undertake detailed geological mapping of the "De la

Colline" and "Sullipek-East" metasomatic hydrothermal systems to better define the spatial distribution,

nature, and intensity of alteration facies associated with copper mineralization.

The work will also include detailed lithological mapping of sedimentary units and intrusive bodies.

Among the six igneous lithologies recognized in the area, the N340-oriented porphyritic dacite dykes are

interpreted as the intrusive bodies most closely associated with hydrothermal alteration and

mineralization.

Drilling Program

The initial drilling campaign will target the eastern extension of the Sullipek-East alteration system.

Inclined and subvertical drill holes are designed to establish a stratigraphic section to evaluate the

spatial distribution of alteration facies, sedimentary host units, and intrusive bodies. The target area also

coincides with a broad conductive anomaly identified through the Company's airborne electromagnetic

survey, suggesting a potentially favorable extension of the known hydrothermal system.

This drilling program is intended to validate geological continuity while refining the Company's broader

understanding of the SV2 copper system.

Management Commentary

Sylvain Laberge, President and Chief Executive Officer of 1844 Resources, commented:

"The launch of our 2026 exploration program marks an important step forward for 1844 as we advance

the SV2 copper system with a more integrated technical approach. By combining historical drilling

data, geological reinterpretation, modern geophysics, and detailed field mapping, we are moving

beyond simple target testing toward a broader understanding of the controls on mineralization. Our

objective this summer is to validate extensions of known mineralization while strengthening the

geological model that will guide future exploration across the district."
