EraNova Confirms Classic Copper-Gold Porphyry System at Ruffner Target, Ruby Creek Project, BC
EraNova Confirms Classic Copper-Gold
Porphyry System at Ruffner Target, Ruby
Creek Project, BC
Vancouver, British Columbia--(Newsfile Corp. - March 25, 2026) - EraNova Metals Inc. (TSXV: NOVA)
(OTCQB: STXPF) ("EraNova" or the "Company") is pleased to announce that 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 its 100%-owned Ruby Creek Project near Atlin, British
Columbia.
These results follow up on the Company's
November 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% Cu
,
13.0 g/t Au from outcrop
, and
36.8 g/t Au from 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 CEO of EraNova
. "The alteration assemblages, sulfide 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 multi-phase intrusive and hydrothermal activity, including cross-cutting granitoid
phases
Surface mineralization includes copper values up to 8% Cu and gold values up to 5.6 g/t Au

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
are spatially
associated with these altered zones.
Supergene modification is evident, with
malachite mineralization and hematite-limonite staining
,
supporting the presence of underlying sulfide mineralization. A younger, cross-cutting quartz-phyric
intrusive phase indicates
multiple pulses of magmatism and fluid flow
, a key characteristic of fertile
porphyry systems.
Whole-rock geochemical data further supports 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 & 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 (November 4, 2025 new
release) high-grade surface results, including copper values up to 8% Cu (with 1.2 g/t Au) and gold
values up to 5.6 g/t Au (with 0.9% Cu) from outcrop and subcrop of the altered feldspar-phyric porphyry.

Next Steps
The Ruffner target will be a priority focus for ongoing 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.

Qualified Person
Mr. Nicholas Clive Aspinall, M.Sc., P.Eng., is a consulting geologist to EraNova and is a "qualified
person" as defined by National Instrument 43-101. Mr. Aspinall has reviewed and approved the technical
information contained in this news release.
QA/QC
Rock samples were analyzed at Bureau Veritas laboratories in Whitehorse, Yukon and Vancouver,
British Columbia, using industry-standard analytical methods. Samples were analyzed using modified
aqua regia digestion with ICP-MS for multi-element analysis and fire assay for gold, including metallic
screen analysis where appropriate. Over-limit base metal samples were re-analyzed using multi-acid
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.
