Enduro Metals Geophysics Defines 4 Km Andrei Target at Newmont Lake
ENDURO METALS GEOPHYSICS DEFINES 4 KM ANDREI TARGET AT NEWMONT LAKE
October 6, 2025, Vancouver, British Columbia – Enduro Metals Corporation (TSXV: ENDR) (“Enduro”, “Enduro
Metals” or the “Company”) reports 2025 geophysical results that confirm the prospectivity of the Andrei
porphyry copper‑gold (Cu‑Au) target at its 100%-owned 688 km² Newmont Lake Project in the Golden Triangle
of British Columbia (Figure 1). The program comprised a 2,000 line-kilometer high-resolution airborne magnetic
survey over the Andrei and Twin targets and 20 line-kilometers of ground induced polarization (“IP”) over the
Andrei target.
Highlights:
• Andrei prospectivity confirmed: high-resolution magnetics and IP define a large, coherent, coincident
geophysical footprint consistent with a porphyry system at Andrei; results will be used to select and
prioritize 2026 drill targets.
• Airborne magnetics: 2,000 line-kilometres of magnetic surveying at 100 metre line spacing completed
in over the Andrei and Twin targets using SHA Geophysics’ Heli-GT system. Large magnetic anomalies
have been outlined.
• Ground IP: 20 line-kilometers of ground IP surveying completed at the Andrei porphyry target (12 lines
at 400 metre spacing plus 1 longitudinal lin e) has delineated a 4 km by 1.2 zone of elevated
chargeability. T wo internal zones exceed 15 mv/v , broadly coincident with high resistivity and
magnetic highs.
• Geological mapping at Andrei shows a large mineralized system characterized by low ‑sulfur,
magnetite‑rich alteration (replacement masses, breccia infill, stockworks and sheeted veins) with
lesser pyrite and local chalcopyrite‑bornite. A late iron carbonate vein system with associated barite
and minor quartz is copper bearing with large masses of chalcopyrite and local bornite. Older Enduro
sampling at North T oe indicates these veins can be gold bearing. All geochemical sampling results
from 2025 remain outstanding.
Robert Cameron, CEO states: “ Newmont Lake continues to exceed our expectations for delivering large and
meaningful exploration targets. The magnetic and IP surveys along with surface mapping and sampling
completed this season at Andrei have defined a large copper-gold porphyry system. We now have a coherent set
of coincident geophysical targets in an area with supportive geology and widespread surface copper and gold
occurrences. Andrei is our number one target on the Newmont Lake Property, and the results of our work this
summer will be used to plan a focused inaugural drill program at Andrei in 2026.”

The Andrei Target
Andrei is a large, low-elevation, and easily accessed, porphyry Cu-Au target located in the northern half of the
Newmont Lake Property. It comprises exposures of potassic altered monzonite and diorite intrusions, along with
altered and hydrothermally altered volcanic wall rock, both, characterised by localised micro -vein stockworks,
copper mineral- bearing veins and extensive magnetite alteration on the north and south side a prominent
forested and till covered ridge, a classic porphyry Cu-Au signature.
Extensive mapping and prospecting at Andrei has characterized a large mineralized system dominated by low -
sulfur assemblages giving rise to dominant magnetite alteration as replacement masses, breccia infilling,
stockworks and sheeted veining with associated lessor pyrite and local copper as chalcopyrite and bornite.
These copper bearing showings are exposed on the flanks of the main IP target, which is in most part not
exposed. A late iron carbonate vein system with associated barite and minor quartz is copper bearing with large
masses of chalcopyrite and local bornite. Older Enduro sampling at N orth Toe (the northern side of Andrei)
indicates these veins can be gold bearing

The IP and magnetic survey results (Figures 2 and 3) have mapped a a 4 km by 1.2 km zone of elevated
chargeability with two large internal elevated zones exceeding 15 mv/v coinciding with high resistivity and high
magnetic values centered on the central ridge. The anomaly is open off grid and at depth. Interestingly the
noted copper occurrences are located on the flanks of the main anomaly which is not exposed.

The Twin Target
The Twin target, located at the southwest corner of the property in an area of limited historical exploration and
previously without any airborne magnetic surveys, is a potential 7 km extension of the “Bronson Trend”, a 14 -
kilometre linear alignment of porphyry and porphyry-related deposits that extends from the Quartz Rise deposit
northwest to the new Snip North deposit discovered in 2024 by Seabridge Gold. The Snip North deposit is a
5
large gold and copper rich system hosted by potassic altered tuffs that is interpreted by Seabridge to be a zone
peripheral to an intrusive hosted porphyry Cu-Au deposit (see Seabridge news releases dated October 9, 2024,
January 21, 2025, and June 3, 2025).
The high-resolution magnetic survey ( Figure 5) completed over this target indicates clusters of discreet and
linear magnetic highs suggesting the presence intrusive bodies which will be followed up in future exploration
campaigns. Limited rock and soil and silt sampling was completed in the area in 2025 with all results still pending.
