Etruscus Reviews Rock & Roll Porphyry Potential Following Seabridge’s Snip North Resource

Press Release

Vancouver, BC – June 4, 2026 – Etruscus Resources Corp. (CSE: ETR) (OTC: ETRUF) (FSE: ERR) (“Etruscus” or the “Company”) is pleased to provide an exploration update regarding its 100%-owned Rock & Roll Property (“Rock & Roll” or the “Property”) located in the Golden Triangle region of northwestern British Columbia.

The update follows the recent maiden mineral resource estimate announced by neighbouring operator Seabridge Gold Inc. for its Snip North deposit, part of the Bronson Corridor Project located immediately southeast of Rock & Roll.

Seabridge reported an inferred mineral resource at Snip North totaling 9.2 million ounces of gold, 28.3 million ounces of silver, and 923 million pounds of copper hosted within altered sedimentary and volcaniclastic rocks of the Triassic Stuhini Group and interpreted as part of a bulk-tonnage magmatic-hydrothermal copper-gold porphyry system (See news release dated April 15, 2026).

The Bronson Corridor has been recognized for more than a decade as a significant structurally controlled and mineralized belt within the Iskut region (see BCGS Geofile 2015-4), historically interpreted to terminate south of the Iskut River at the past-producing Snip and Johnny Mountain gold mines. The discovery and subsequent delineation of the Snip North deposit north of the Iskut River, suggests the mineralized corridor may extend farther northwest than previously recognized. Rock & Roll is situated along the interpreted northwest continuation of this trend and shares the same Stuhini Group volcano-sedimentary host rocks associated with mineralization at Snip North. The Company believes the evolving geological interpretation at Snip North has important implications for exploration across Rock & Roll. Despite extensive historical exploration in the region, Snip North was not initially recognized as a significant porphyry-related system, highlighting the potential for significant mineralized systems to remain concealed beneath subtle or distal surface expressions.

Rock & Roll Property Targets

Several targets at Rock & Roll exhibit characteristics consistent with intrusive-related hydrothermal systems and may represent distal or upper-level expressions of porphyry mineralization, including:

• Blackdog Deposit – hosts stratabound sulphide mineralization historically interpreted as VMS-style mineralization, but which may share similarities with stratabound mineralization associated with the Snip North hydrothermal system;
• Kashmir – exhibits porphyry-style alteration and a broad footprint of anomalous copper, gold, and molybdenum mineralization, including rock samples grading up to 5,970 ppm Cu, 51.3 g/t Au, and 0.86% Mo;
• Heather – hosts a 1.0 km by 0.6 km Au-Cu-Mo soil anomaly and gold-silver epithermal veins associated with two induced polarization (“IP”) chargeability anomalies exceeding 25 mV/V;
• Stardust – characterized by an extensive quartz-sericite-pyrite (“QSP”) alteration system coincident with magnetic, resistivity, and chargeability anomalies;
• Zappa – exhibits porphyry-style alteration and mineralization identified through drilling, including a 600 m by 300 m chargeability anomaly extending to surface beneath a 1.1 km long and 250 m wide QSP alteration footprint;
• North Gossan – characterized by two 400 m long and 5 m wide QSP alteration zones associated with anomalous gold geochemistry; and
• Hammer – hosts magnetite-chalcopyrite skarn mineralization, including rock samples grading up to 8.3% Cu, and is associated with a 300 m-wide magnetic-high anomaly that may indicate proximity to an intrusive source.

Collectively, these targets represent a broad spectrum of mineralization styles and alteration systems commonly associated with porphyry environments, including epithermal veining, skarn mineralization, stratabound sulphide replacement, extensive QSP alteration, and porphyry-style geochemical and geophysical signatures. While each target remains at a different stage of exploration, their distribution along the interpreted northwest continuation of the Bronson Corridor warrants systematic re-evaluation within the context of the evolving geological model emerging from Snip North.

The recognition of Snip North as a large, concealed porphyry-related system demonstrates that significant mineralized centres can remain undiscovered despite extensive historical exploration. This supports the application of modern geological interpretation and deep-penetrating geophysical techniques to evaluate the potential for additional porphyry-related systems across the Rock & Roll Property.

Fiore Aliperti, President and CEO of Etruscus, commented:

“The maiden resource at Snip North is a significant development for the region and further supports the interpretation that the Bronson Corridor mineralized belt extends farther northwest than previously recognized. The proximity of the discovery to our property, combined with shared host geology and multiple intrusive-related targets identified across Rock & Roll, reinforces our belief that the property remains highly prospective for additional discoveries. We are particularly encouraged by the evolving understanding of Snip North as a concealed porphyry-related system, as several targets on our property display geological, alteration, and geophysical characteristics that warrant further evaluation under a similar exploration model.”

Planned 2026 Exploration Strategy

The advancement of the Snip North deposit provides an important geological framework for evaluating the exploration potential of the Rock & Roll Property. In particular, the recognition of Snip North as a large porphyry-related system with relatively subtle surface expression highlights the importance of reassessing historical datasets for indicators of concealed mineralization.

As a first step, Etruscus has initiated a comprehensive compilation and review of historical geological, geochemical, geophysical, and drilling data across the Property. The objective of this work is to evaluate existing targets within a district-scale geological framework and identify characteristics that may indicate the presence of concealed intrusive centres and associated hydrothermal systems.

Following completion of the review, the Company expects to prioritize target areas for additional geophysical investigation. Airborne and ground-based surveys, including ZTEM and Magnetotelluric (“MT”) methods, are being evaluated to identify resistivity, conductivity, and magnetic signatures that may be associated with concealed porphyry systems. Attention will be directed toward areas with limited historical deep-penetrating geophysical coverage, including portions of the Property adjacent to the interpreted northwest continuation of the Bronson Corridor.

Targets including Zappa, Blackdog, Heather, Stardust, Hammer, Kashmir, and North Gossan will be assessed as part of this process. These targets exhibit varying combinations of porphyry-style alteration, sulphide mineralization, geochemical anomalies, skarn development, and geophysical responses that may represent vectors toward larger intrusive-related systems at depth.

Results from the compilation and geophysical programs will be used to refine exploration priorities and guide future field programs, including geological mapping, geochemical surveys, and drilling. The Company believes this systematic approach will strengthen its evaluation of the broader porphyry potential of the Rock & Roll Property and its position along the interpreted northwest continuation of the Bronson Corridor mineralized belt.
