Enduro Metals Completes Inaugural Drill Program at Andrei; Identifies Porphyry
and Epithermal-Style Systems
August 24, 2026, Vancouver, British Columbia - Enduro Metals Corporation (TSXV: ENDR) (“Enduro”, “Enduro
Metals” or the “Company”) is pleased to announce the completion of its 2026 inaugural drill program at the
Andrei copper -gold porphyry target, located within the Company’s 100% -owned Newmont Lake Project in
British Columbia’s Golden Triangle.
Seven diamond drill holes totaling 2,700 metres tested the two principal chargeability anomalies within an open-
ended, greater than four-kilometre combined chargeability and magnetic anomaly at Andrei.
Initial geological observations from the program include:
• Hole AD -03 intersected porphyry style alteration and quartz -sulphide veining that increased in
abundance downhole. The mineralization and alteration encountered towards the end of the hole are
interpreted to represent a peripheral portion of a porphyry system that remains open to the northeast
and southeast.
• Hole AD-04 intersected alteration and veining characteristic of a low -sulphidation epithermal system,
including an interval of intense vuggy and banded quartz- carbonate-pyrite veining, stockworks and
breccias between 63 m and 92 m downhole.
• Hole AD-06 intersected a further interval of low -sulphidation-style quartz-carbonate-sulphide veining
and breccias between 436 m and 444 m downhole.
• Phase 2 e xploration is underway across the Newmont Lake Project, including a planned 20 line -
kilometre IP survey to extend geophysical coverage northeast of the Andrei drilling, together with
target-definition work at FK, Southmore, Camp Zone, Burgundy and the 72 Zone.
• All drill core assays are pending and are expected to be received later in the year.
Robert Cameron, Chief Executive Officer of Enduro, commented:
“Completion of our inaugural drill program at Andrei has provided the first subsurface geological information
across both of the principal chargeability targets within this extensive geological system. Initial observations
indicate that the northeast anomaly is the more prospective. Of particular interest, AD-03 encountered porphyry-
style alteration and quartz -sulphide veining that increases in abundance downhole, while AD -04 and AD -06
identified low-sulphidation epithermal-style veining and brecciation in the northeast target area. Our ongoing
geological work and upcoming IP survey will provide additional information that, together with the pending
assay results, will help us refine our geological model and prioritise the next phase of exploration at Andrei.”
Andrei 2026 Drill Program
Enduro’s 2026 inaugural drill program at Andrei, as set out in the Company’s press release dated June 22, 2026,
tested targets within an open-ended 4-kilometre combined chargeability and magnetic anomaly, part of a larger
14 kilometre magnetic-high trend that outlines the larger Andrei trend.
The drill target comprises two principal areas of elevated chargeability. Holes AD-01, AD-02, AD-05 and AD-07
tested the southwest anomaly and holes AD-03, AD-04 and AD-06 tested the northeast anomaly (Figure 2 and
Table 1).

The program completed 2,700 m of drilling in seven holes. Fewer metres were completed than initially planned
due to locally challenging drilling conditions and limited availability of drill-contractor personnel, which reduced
drill productivity during the contracted period. Drill hole summaries are provided below. Intervals reported are
core intervals and true widths or dimensions are unknown.
Figure 1: Location Map
Northeast Anomaly
AD-03 – This drill hole targeted a coincident magnetic high and chargeability high in an area with limited outcrop
and was drilled to a depth of 491 m.
The hole intersected a series of fine- grained feldspar porphyry monzonite dykes that cut epidote -chlorite-
magnetite altered basalts. The feldspar porphyry monzonite dykes typically contain weakly developed
stockwork chlorite -pyrite+/-magnetite veins and quartz -pyrite+/-chalcopyrite+/-molybdenite veins that
increase in abundance downhole. The quartz-sulphide veins are commonly haloed by k -feldspar alteration
below 183 m down hole.
The porphyry -style mineralization and alteration encountered toward the end of AD -03 are interpreted to
represent a peripheral portion of a porphyry system, with alteration and veining increasing at depth. The hole
was terminated at 491 m due to drilling conditions.
AD-04 – This hole was collared 335 m north -northwest of AD-03 and 135 m lower in elevation. The hole was
designed to test the continuation of a large chargeability high that was also tested by AD -03. It intersected a
zone of alteration and veining typical of a low-sulphidation epithermal system within basalts and feldspar
porphyry monzonites.
Between 63m and 92m downhole, the hole intersected a zone of intense vuggy and banded quartz-carbonate-
pyrite stockworks and breccias with minor chalcopyrite+/ -molybdenite veining. The orientation of this zone is
currently unknown.
Below 92 m the hole intersected a series of faults and feldspar porphyry monzonite units before faulting
ultimately closed the hole off at 192 m.

1391-3053-7247, v. 1
AD-06 – Hole AD-06 was drilled northward from the same drill pad as hole AD-03 toward hole AD-04, with the
objective of avoiding the north-dipping faults encountered in AD-04.
The hole encountered fewer faults and stayed within epidote-chlorite altered basalt with minor monzonite units
similar to those observed in hole AD-03.
Between 436 m and 444 m downhole it intersected low-sulphidation style epithermal quartz-carbonate-
sulphide veining and brecciation. The hole was lost due to drilling difficulties at a final depth of 507 m.
Southwest Anomaly
AD-01 – The first hole of the 2026 program, AD -01, tested to depth a series of scattered outcrops containing
magnetite or hematite veining and stockworks with disseminated chalcopyrite.
The hole intersected feldspar porphyry monzonite units with magnetite veining and trace chalcopyrite in the
upper 57 m with alteration and mineralization weakening downhole. It was terminated early at 142 m.
AD-02 – This hole e ncountered various phases and varieties of monzonite with less er intervals of basalt. It
encountered pervasive moderate chlorite alteration with minor pyrite throughout , as well as local zones of
intense potassic alteration characterised by stockwork potassium feldspar veining. The hole ended at its planned
depth of 505 m.
AD-05 - AD-05 targeted a large chargeability anomaly. It cored a sequence of basalts and sediments with minor
monzonite dykes to 301 m where it cored a large granodiorite body and monzonite dykes. The granodiorite is
interpreted to be an older Paleozoic intrusion. The hole was terminated at 505 m.
AD-07 – AD-07 targeted a zone of pyrite stockwork veining and potassic altered monzonite identified on surface.
The upper 75 m of this hole intersected chlorite-pyrite-magnetite altered basalt and monzonite with traces of
chalcopyrite and molybdenite . Following the intersection of several faults, alteration weakened to the south
and at depth. This is interpreted as indicating that either this hole was drilling away from a hydrothermal source
or that the mineralized system has been structurally displaced . Hole AD-07 was completed to a final dept h of
358 m.

Ongoing Exploration
Enduro’s 2026 exploration program at Newmont Lake continues including a planned 20 line-kilometre induced
polarization survey to extend the existing IP coverage at Andrei to the northeast and extensive mapping and
sampling at the Southmore target and the recently acquired FK target northeast of Andrei.
The planned IP survey will extend existing coverage at Andrei northeast of the 2026 drilling, where the
encouraging geological observations from AD-03, AD-04 and AD-06 occur near the limit of the 2025 survey. The
5
1391-3053-7247, v. 1
objective is to better define the extent and geometry of the chargeability response and provide additional
vectors for follow up exploration.
Mapping and sampling at Southmore and the recently acquired FK targets will focus on defining the geology,
alteration and mineralisation of these targets and identify ing priority areas for further geophysical work and
potential future drill testing.
Detailed geological work at the historical Camp Zone, located south of McLymont, will follow up the encouraging
results from prospecting in 2025 , where sampling returned high -grade gold values from narrow sub -metre
quartz pyrite veins within shear zones of up to 113 g/t Au with 142 g/t Ag (see news release dated January 8,
2026 for detailed QA/QC). The Camp Zone was the original discovery at Newmont Lake and has not been subject
to significant exploration since 1987.
At the Burgundy and 72 Zone copper -gold porphyry system, surface geological work and re -examination of
historical drill core will be used to refine Enduro’s geological model, improve its understanding of the controls
on mineralisation and identify priority areas for future exploration.
