Auriginal Mining Corp. Commences Trading as

AUME, Advances Roger Drilling Plans

Highlights:

Auriginal first day of trading as AUME on the Toronto Venture Exchange.

Drill planning to test the off-hole VMS conductors detected by downhole geophysical surveys on

the Roger property has been completed.

Phase I drilling includes about 5,000 metres and will intersect the favourable gold-rich base metal

sulphide horizon at the 500 m vertical level.

Toronto, Ontario--(Newsfile Corp. - December 4, 2025) - We are pleased to announce that Kintavar

Exploration Inc. has officially been renamed Auriginal Mining Corp.

(TSXV: AUME)

("

Auriginal

" or the

"

Company

") and commenced trading on the TSX Venture Exchange as AUME.

In addition, the Company reports that drill planning for the winter 2026 Phase I program at the Roger

project in the Chibougamau region has been completed for a February startup.

Drill Program Rational

The Roger deposit has long been viewed as a porphyry-style Au-Cu system. Auriginal's recent

reinterpretation, based on relogging, resampling, geochemistry, and age dating, now suggests that the

historical gold-copper deposit may sit below a deeper gold-rich VMS system up stratigraphy.

A continuous, sulphide-bearing marker horizon has been traced for at least 1.5 km, hosted in altered

felsic to intermediate volcanic rocks typical of VMS environments. Geochemical and geological

signatures show strong similarities to Agnico Eagle's LaRonde 20N massive sulphide deposit,

reinforcing the potential for a second, high-grade base-metal deposit at depth.

Downhole EM surveys in nine historical holes have identified multiple strong off-hole conductors directly

beneath and adjacent to the deepest drilling at Roger.

NE Target Area

Multiple moderate to strong conductors occur about 100 m below earlier drilling.

An especially strong 500-siemens plate lies 250-300 m NE of previous holes, aligned with

historical Cu-Zn-Ag-Au intercepts.

This forms the top-priority drill target for potential massive sulphides.

SW Target Area

Off-hole formational conductors strengthen southwestward, coincident with historical high-grade

base-metal intervals.

This trend suggests a second potential massive sulphide center.

Auriginal has completed its diamond drill planning to intersect the gold-rich massive sulphide horizon,

targeting these newly defined conductor plates with the explicit objective of making a new VMS

discovery below the existing gold system.

The 2026 program includes:

Minimum 4,675 m of diamond drilling (

see

Table 1,

Figure 1

) of the Roger mineralized system.

Testing conductive plates at the 500 m vertical level across 1.5 km of strike (

see

Figure 2

).

Downhole EM in every new hole to tighten vectoring toward the core of the VMS system.

This is the first focused drill campaign designed specifically to test this new VMS interpretation and the

high-priority targets defined by borehole electromagnetic surveys (BHEM). Drilling will also test the deep

continuation of the historical porphyry-style or intrusion-related Au-Cu deposit on the property, which is

still open at depth.
