ETRUSCUS ADVANCES TOWARD PORPHYRY DISCOVERY AT ZAPPA TARGET, GOLDEN TRIANGLE, B.C.

ETRUSCUS ADVANCES TOWARD PORPHYRY DISCOVERY AT ZAPPA TARGET, GOLDEN TRIANGLE, B.C.

VANCOUVER, BC, Nov. 25, 2025 /CNW/ - Etruscus Resources Corp. (CSE: ETR) (OTC: ETRUF) (FSE: ERR") (the "Company" or "Etruscus") is pleased to report results from its 2025 diamond drill program at the Zappa Porphyry Target, a high-priority copper-gold porphyry prospect located on the Company's 100%-owned Rock & Roll Property (the "Property") in British Columbia's prolific Golden Triangle. The inaugural program totalled 1,311 metres ("m") across three drill holes (See Map 1) and was successful in advancing the Company's understanding of the system, vectoring closer to a potential mineralized porphyry intrusion.

Drilling focused on a large surface alteration and chargeability anomaly, intersecting intensely altered volcanic and sedimentary rocks with zones of potassic alteration. Geochemical and alteration patterns indicate that hole RR25-03 was nearest to the heat source, suggesting that the porphyry intrusion may lie to the northeast, beneath the Twin Glacier where further drilling is warranted. The discovery of this alteration extends the Bronson Porphyry Trend onto the Property and greatly increases its prospectivity (See Map 2).

Fiore Aliperti, President and CEO of Etruscus commented, "Each step in a porphyry exploration program provides critical data to refine our understanding of the mineralized system. The identification of potassic and QSP alteration is a strong indicator that we're close to the heart of the system, a significant advancement in our exploration. Several nearby discoveries in the Golden Triangle required multiple programs to vector in and locate mineralized zones, and our first-ever drill results at Zappa clearly show we're on the right path."

Highlights:

• Hole 3 returned the strongest porphyry indicators with elevated molybdenum assays and identification of potassic feldspar alteration associated to sericite veining.
• Intense quartz-sericite-pyrite (QSP) alteration was encountered in every hole, highlighting the strength and size of the hydrothermal system.
• North Gossan mapping, located 1 km north of Zappa, suggests the same hydrothermal system extends over a much larger footprint; and
• Newly identified quartz-sulphide veins near North Gossan (See Map 1) returned up to 20.1% Pb,13.9% Zn, and 0.6% Cu.

Drill Hole Summary:

RR25-01

Hole 1 was designed to test a high chargeability anomaly on the western edge of the Zappa target. The hole was drilled steeply to the north and encountered mixed sediments and volcanic units including black shales, andesites and volcanic tuffs. Porphyry alteration predominantly as quartz-sericite-pyrite was prevalent from top of hole to 151 m with total replacement of primary textures (See Graphic 1). This alteration contained up to 5% pyrite as disseminations, stringers and geochemical data confirmed strong hydrothermal alteration. Below this, the hole continued into black shales and lapilli tuffs to end at 344 m. The chargeability anomaly that was being targeted was likely correlated to sulphide-rich hydrothermal alteration and graphitic black shales.

RR25-02

Hole 2 was drilled from the north to the south, targeting strong alteration mapped at surface. Drilling encountered sporadic QSP alteration from 0 to 32 m, 50 to 62 m, 210 to 228 m, and from 258 to 274 m. Intense zones up to 5% pyrite were encountered with multiphase quartz veining and total replacement of host lithology. At 310 m, multiple potassically altered lithic clasts up to 15 cm in size were identified in the lapilli tuff, pointing towards the existence of a nearby porphyry core (See Graphic 2).  Petrographic work on these clasts is underway.

RR25-03

Hole 3 was collared at the eastern edge of the exposed surface anomaly and drilled north underneath the Twin Glacier. Hydrothermal alteration was identified from 42 to 56 m, 136 to 188 m, and from 276 to 368 m. Most significantly, hole 3 demonstrated the strongest geochemical and lithological correlation to a probable porphyry intrusion that may lie to the northeast, underneath the Twin Glacier.

A unique unit appearing to either be a crystal tuff or a faintly porphyritic intrusion (thin section work pending) was intercepted from 276 to 368 m and contained weak to moderate potassium feldspar alteration adjacent to sericite veinlets. This alteration is confirmed with elevated potassium geochemistry and rare grains of chalcopyrite, both exemplifying high temperature alteration. Molybdenum, a strong indicator of a porphyry halos, was elevated in a QSP stockworked quartz zone from 136 to 188 m and in another heavily altered andesite breccia zone from 390 to 484 m (See Graphic 3).

From 0 to 40 m, a quartz feldspar porphyry dike that is likely related to young Hoodoo volcanism returned surprisingly elevated rare earth element (REE) values. Elevated cerium, lanthanum, niobium and yttrium all suggest a highly evolved magma and demonstrated values near those encountered at the Pheno Claims to the north where a 5 km REE target is being also being advanced.

North Gossan

The North Gossan represents argillic/clay altered felsic volcanics in multiple outcrops across an area of 900 m strike length located 1 km to the north of the Zappa target.  Elevated pathfinder elements such as arsenic and silver and weakly anomalous gold suggest the gossans are related to the same system as the Zappa target, possibly demonstrating a much larger footprint than previously identified. The gossans have selectively altered felsic volcanics between lenses of non-receptive black shales.

In completing geological mapping in this area, we encountered a 10-30 cm wide quartz sulphide vein striking approximately 30 m in length that returned 0.3% and 0.6% copper along with lead and zinc values up to 20.1% and 13.9% respectively. These samples could represent distal polymetallic and base metal veins related to a porphyry intrusion and further reinforce this area as a porphyry center. Identification of propylitic alteration between the North Gossan and the Zappa further backs up this hypothesis.

Next Steps:

Etruscus plans to expand drilling north-eastward beneath the Twin Glacier, where geochemical and alteration vectors point to a concealed porphyry intrusion. Follow-up mapping and geophysics will also continue at North Gossan to define additional drill targets.

QA/QC Statement

The Company has adopted a rigorous quality assurance and quality control ("QA/QC") program to ensure best practices in sampling of all rock, soil and silt material.  The Company's samples are assayed by ALS Geochemistry Labs which has facilities in Terrace and North Vancouver, BC. All rock samples were crushed to 70% pass 2mm fraction, and then a 250g split was pulverized to better than 85% passed a 75-micron screen.  Multi-element analysis for gold copper exploration was performed by ALS using four acid digestion ICP-MS package (ME-MS61). Gold grades were returned by fire assay (Au-ICP21). Samples that returned above detection limits in silver, copper, lead and zinc were reanalyzed with appropriate ore grade analysis to determine absolute values. For REE samples, a lithium borate fusion analysis was performed using ALS package ME-MS81 for full digestion of REE minerals.

Etruscus undertook an internal QA/QC procedure that involved systematically inserting standard samples at an interval of 1 out of 10 samples. These included certified reference material as well as blank samples and duplicates.

ALS is an independent provider of geochemical laboratory services for the exploration and mining industries and is an ISO 17025 (Testing and Calibration) and ISO 9001 (Quality Management System) accredited laboratory.
