ERANOVA CONFIRMS CLASSIC COPPER-GOLD PORPHYRY SYSTEM AT RUFFNER TARGET, RUBY CREEK PROJECT, BC

Detailed petrographic analysis and whole-rock geochemical results support the presence of a classic porphyry-style copper-gold system at the Ruffner target, located on Eranova Metals Inc.'s 100-per-cent-owned Ruby Creek project near Atlin, B.C.

These results follow up on the company's Nov. 4, 2025, news release, which first identified high-grade copper-gold mineralization associated with a feldspar-phyric porphyry intrusion, including grab samples returning up to 8.1 per cent copper, 13.0 grams per tonne gold from outcrop, and 36.8 g/t Au from a talus float. Petrographic and geochemical work announced today provides strong confirmation of the underlying porphyry system.

"These results support that the Ruffner target hosts a classic porphyry copper-gold system and provide important geological context for the high-grade surface values we reported previously," said Meredith Eades, president and chief executive officer of Eranova. "The alteration assemblages, sulphide mineralization and host rock chemistry all point to a fertile system with scale potential, and we are now advancing toward drill testing to evaluate that potential. Importantly, Ruffner is located just 3.6 kilometres from the Adanac molybdenum deposit, which is advancing toward a NI 43-101-compliant PEA. Together, these assets highlight the broader district-scale opportunity at Ruby Creek, where our objective is to advance both development and discovery in parallel."

Highlights:

• Petrography confirms classic porphyry alteration assemblages, including phyllic (sericite), propylitic (chlorite-epidote) and argillic alteration;
• Disseminated chalcopyrite and pyrite mineralization observed within altered intrusive host rocks;
• Whole-rock geochemistry classifies host intrusion as diorite to granodiorite;
• Evidence of multiphase intrusive and hydrothermal activity, including crosscutting granitoid phases;
• Surface mineralization includes copper values up to 8 per cent copper and gold values up to 5.6 g/t Au;
• Ruffner target located approximately 3.6 kilometres from the Adanac molybdenum deposit.

Ruffner -- confirmed porphyry copper-gold system

Petrographic analysis of mineralized outcrop samples confirms that the Ruffner target hosts a well-developed porphyry-style hydrothermal system. The host rocks are interpreted as intermediate intrusive compositions (monzodiorite to granodiorite), with alteration and mineralization consistent with productive copper-gold porphyry environments.

Intense alteration has partially to completely overprinted primary textures, with pervasive sericitic (phyllic) alteration of feldspars and widespread propylitic alteration, including chlorite and epidote replacing primary mafic minerals. Disseminated chalcopyrite and pyrite mineralization is spatially associated with these altered zones.

Supergene modification is evident, with malachite mineralization and hematite-limonite staining, supporting the presence of underlying sulphide mineralization. A younger, crosscutting quartz-phyric intrusive phase indicates multiple pulses of magmatism and fluid flow, a key characteristic of fertile porphyry systems.

Whole-rock geochemical data further support this interpretation, classifying the host intrusion as diorite to granodiorite, and distinguishing it from surrounding intrusive phases within the broader Ruby Creek system.

Whole-rock geochemical analysis of representative samples, including immobile element classification (Winchester and Floyd, 1977), indicates the host intrusion is diorite to granodiorite in composition. The porphyry unit is geochemically distinct from surrounding intrusive phases, and field relationships suggest it is younger than the 4th of July batholith, the predominant granitoid mapped at surface in the area.

These geological characteristics are consistent with the previously reported (Nov. 4, 2025, new release) high-grade surface results, including copper values up to 8 per cent Cu (with 1.2 g/t Au) and gold values up to 5.6 g/t Au (with 0.9 per cent Cu) from outcrop and subcrop of the altered feldspar-phyric porphyry.

Next steps

The Ruffner target will be a priority focus for continuing exploration as the company advances work toward drill readiness. Planned activities include:

• Detailed geological mapping and structural interpretation;
• Additional geophysical surveys to define subsurface extent;
• Advancement of drill targeting, subject to permitting and financing.

These activities form part of the company's broader strategy to advance multiple high-impact targets across the Ruby Creek property, with the objective of generating drill-ready targets and future discovery catalysts.

Quality assurance/quality control

Rock samples were analyzed at Bureau Veritas laboratories in Whitehorse, Yukon, and Vancouver, B.C., using industry standard analytical methods. Samples were analyzed using modified aqua regia digestion with ICP-MS for multielement analysis and fire assay for gold, including metallic screen analysis where appropriate. Overlimit base metal samples were reanalyzed using multiacid digestion and ICP-ES. Whole-rock characterization was conducted by ithium borate fusion coupled with ICP-ES/MS analysis. All results passed internal laboratory QA/QC procedures. Petrography was conducted by qualified personnel at Vancouver Petrographics.
