Auriginal Returns Wide Gold and Copper Intersections at Roger Project in Chibougamau, Expands Mineralization 125 meters at Depth
Auriginal Returns Wide Gold and Copper
Intersections at Roger Project in
Chibougamau, Expands Mineralization 125
meters at Depth
Highlights:
125.3 m grading 0.67 g/t Au, including 20.0 m at 1.94 g/t Au, returned in hole AUR-26-07, the
widest intercept of the program to date, extending the Roger zone by at least 125 metres at depth
Near-surface copper-gold confirmed: 34.5 m of 0.69 g/t Au and 0.14% Cu from just 70.5 m
downhole in AUR-26-06
High-grade gold at depth: 50.4 g/t Au over 0.5 m at 572.7 m and 9.1 g/t Au over 2.5 m at 596.0 m
in AUR-26-06 and 12.2 g/t Au over 1.1 m in AUR-26-05, demonstrating the high-grade endowment
persists throughout the system
Phase 1 drilling complete: 10 holes totaling 7,325 m have expanded the Roger mineralized
footprint approximately 700 m southwest, 400 m northeast, and more than 100 m at depth, growth
that will be captured in the revised Mineral Resource Estimate now underway
The Roger is characterized as wide anomalous copper- and gold-bearing sulphide intervals over
hole lengths of 200-250 m in all holes, commencing near surface.
Phase 2 drilling is now on the fourth hole of a 12-hole, 6,400 m drill program
Toronto, Ontario--(Newsfile Corp. - September 1, 2026) -
Auriginal Mining Corp. (TSXV:
AUME)
("
Auriginal
" or the "
Company
") is pleased to report that encouraging results continue to be
returned from Phase 1 Roger diamond drilling. The new results, in combination with our Phase 2
definition drilling, will supplement an expanded Mineral Resource for the historical Roger Zone being
undertaken.
The new assays continue to demonstrate the two features that define Roger's investment case,
exceptional width and consistent grade near surface, punctuated by high-grade gold. Hole AUR-26-07
returned the standout intercept of the program to date, 125.3 m grading 0.67 g/t Au from 346.0 m,
including 20.0 m at 1.94 g/t Au, this single intersection extends the Roger zone by at least 125 metres at
depth.
Higher in the system, AUR-26-06 cut 34.5 m of 0.69 g/t Au and 0.14% Cu beginning just 70.5 m
downhole, including 6.0 m at 1.85 g/t Au and 0.34% Cu, confirming that meaningful copper-gold
mineralization starts near surface. AUR-26-05 added 23.5 m of 1.12 g/t Au, including a high-grade
interval of 12.2 g/t Au over 1.1 m, while late intercepts of 50.4 g/t Au over 0.5 m at 572.7 m and 9.1 g/t Au
over 2.5 m at 596.0 m
depth in AUR-26-06 demonstrates that the high-grade gold endowment persists
well below the historical resource.
Each hole reported intersected mineralization over broad intervals, the system remains open in all
directions, and each of these intercepts falls above the 0.2 g/t Au cut-off being applied to the revised
Mineral Resource Estimate, meaning this drilling is not just extending the geology, it is directly adding to
the resource base currently being calculated.
"Drilling continues to support our view of a significantly expanded porphyry Cu-Au resource at Roger
below and along strike from historical drilling on the property and has confirmed the presence of an
overlying gold-rich VMS horizon," said Peter Cashin, Auriginal Mining Corp's CEO. "We are seeing
strong mineralization in all holes, which remains open below and to the southwest and northeast of the
previous limits of Roger zone. Phase 2 drilling is well underway and is showing some of the strongest
sulphide mineralization observed to date."

Phase 1 Drilling Expands Roger Mineralized Footprint
Auriginal's Phase 1 drilling program was designed to test extensions of the historical Roger copper-gold
mineralization and further evaluate the Company's geological interpretation of the broader mineralized
system. Drilling to date has extended the known porphyry-style mineralization approximately 700 metres
southwest and 400 metres northeast of the historical drilling limits, while also extending the depth limits
of mineralization by more than 100 metres. The Roger mineralized system remains open in all directions.
A total of ten drillholes for 7,325 m were completed in this Phase of the Roger program.
Assays for the holes AUR-26-05 to -07 are herein reported (

Roger: At the Centre of a Major Mining Resurgence*
Auriginal Mining's Roger Project is surrounded by a growing concentration of large, advanced mineral
resources in the Chibougamau-Chapais district (
see
Figure 1). The historic mining camp has produced
more than 6.5 Moz of gold and 1.6 billion lbs of copper and is attracting renewed investment from major
international mining companies.
Nearby projects include:
Nelligan Mining Complex - IAMGOLD: 4.3 Moz Indicated + 7.5 Moz Inferred gold
Croteau East Project - IAMGOLD: 640,000 oz. Inferred gold
Chibougamau Project - Central Asia Metals: 14.9 Mt @ 3.3% Cu
Eq
Windfall - Gold Fields: 7.4 Moz gold resources, including 4.1 Moz M&I
Opemiska - XXIX Metals Corp.: 2.4 billion lbs. @ 0.74 % Cu

This concentration of substantial gold and copper resources underscores the scale and strategic
importance of the mineral district surrounding Roger, providing Auriginal with exposure to a rapidly re-
emerging Québec mining camp.
$2.0 Million Phase 2 Definition Drill Program Underway
Following the expansion demonstrated during Phase 1, Auriginal has allocated an additional $2.0 million
to Phase 2 definition drilling at Roger. The program is designed to provide sufficient drill density across
the newly identified extensions of the Roger mineralized system to support their potential inclusion in a
future MRE. Based on PLR's initial review, drilling at approximately 125-metre spacing has been
recommended across portions of the newly defined mineralized extensions to support evaluation for
potential classification within an Inferred Mineral Resource.
The Company expects the broader resource work incorporating the expanded drilling footprint to follow
the October update, with additional resource work tentatively targeted for later in 2026 or early 2027. All
currently planned Phase 2 drilling and associated technical work is fully funded.
The Phase 2 drilling is currently of the fourth hole of a twelve-hole, 6,250 m program (
see
Figure 2). The
drilling is planned to intersect the Roger porphyry zone above the Phase 1 drilling at the 375 m and 150
m vertical level (
see
Figure 3
)
. Some of the strongest pyrite-chalcopyrite mineralization was intersected
(
see
Plates 1 & 2, Hole AUR-26-12 from 170.0 to 224.0 m) . This new drill core will be sent to our lab for
analysis soon.
