AuMEGA Metals Completes Initial Drilling at

Isle aux Morts Granite and Cape Ray West

Initial diamond drilling program at Isle aux Morts Granite and

Cape Ray West was completed with assays pending. Current

drilling focus shifts to Bunker Hill with drilling planned across

multiple targets.

Toronto, Ontario--(Newsfile Corp. - September 23, 2026) -

AuMEGA Metals Ltd

(ASX: AAM) (TSXV:

AUM) (OTCQB: AUMMF)

("AuMEGA" or "the Company") is pleased to announce the completion of its

initial diamond drilling program at the Isle aux Morts Granite ("IAMG") and adjoining Cape Ray West

target area along the Cape Ray Shear Zone ("CRSZ") in Newfoundland and Labrador, Canada (Figure

1).

The initial program represents the first drill test of any kind into the IAMG. The program provided initial

drill testing of several geological concepts, including structurally controlled gold mineralisation and the

potential for an intrusion-related magmatic-hydrothermal system (Figure 2)

1

.

The Company is now awaiting laboratory assay results, which are expected to be received progressively

over the coming weeks.

Highlights

Initial diamond drilling at the IAMG and Cape Ray West is complete, with 9 holes totaling

approximately 2,087 metres drilled.

The program included an extensional drill hole at Window Glass Hill and the first hole into the Early

Bird target, a new structurally controlled gold target

2

.

The drill rig has been mobilised to Bunker Hill, where drilling has already commenced and will

continue for as long as weather conditions permit.

The Company expects to return to drilling Cape Ray in mid-Q4 2026 to undertake follow-up drilling,

including the potential deeper testing of targets within and adjacent to the IAMG.

Isle aux Morts Granite

The IAMG was identified as a priority drill target following the integration of geological mapping,

geophysics and surficial geochemistry. This work defined a demagnetised central domain associated

with anomalous bismuth, molybdenum and copper (till sampling), interpreted as a potentially fertile

magmatic-hydrothermal system (Figure 3)

.

The Company completed seven drill holes within the IAMG, testing targets within the intrusive core, along

its western flank and across the interpreted contact between the granite and surrounding sedimentary

rocks. While most holes were designed to approximately 200 metres depth, two holes targeting the core

of the intrusion were extended to 351 metres and 372 metres to provide deeper geological coverage of

the interpreted magmatic-hydrothermal system.

Three holes tested the western flank of the IAMG, targeting a cluster of anomalous gold-in-till results

spatially associated with a north-trending structure. A further hole was completed in the southwestern

portion of the granite to test the intrusive-sedimentary contact adjacent to a separate gold-in-till trend.

Assay results are expected progressively over the coming weeks. The Company plans to return to the

area in mid-Q4 2026 for follow-up drilling, which may include deeper testing of priority targets within and

adjacent to the IAMG.

Window Glass Hill and Early Bird

The program included a single drill hole at

Window Glass Hill

, testing extensions of the Mineral

Resource to the northeast and for a possible repeat of an ore shoot at depth

4

.

AuMEGA also completed the first hole at

Early Bird

, which is located 1.2 kilometres to the west of the

Company's BP deposit. Early Bird is a new gold target identified from last year's surficial geochemical

survey that delivered the highest gold-in-till result of the survey. The Early Bird target is defined by an

interpreted north-east plunging antiform hinge intersected by subparallel north-east striking shear zones,

with coincident zones of magnetic destruction, anomalous gold and base metals in till, and mapped

chalcopyrite-bearing quartz veins at surface.

Assays from Window Glass Hill and Early Bird are pending.

Bunker Hill

The drill rig has been mobilised to Bunker Hill, where the Company will test a pipeline of high-priority

gold and polymetallic targets across this expansive and underexplored project area

5

.

Drilling will focus on three priority target areas (Figure 4):

Southeast Base Metals Target:

A previously undrilled polymetallic target defined by an east-

north-east striking high-tenor lead anomaly coincident with silver, copper and zinc till anomalism.

Branch Fault Corridor:

A structurally controlled gold target associated with a prominent second-

order fault corridor containing demagnetised fault jogs and splays. The target is supported by

coherent gold-in-till anomalism with coincident silver, lead and antimony.

Bunker Hill West:

A gold target located where several secondary structures intersect the

principal CRSZ. The target is characterised by prominent structural disruption, demagnetisation

and fault splays associated with the northwest-southeast structural corridor.

The program is designed to test a range of geological concepts, from structurally controlled orogenic

gold mineralisation to a potential polymetallic copper-lead-zinc-silver system. Drill sequencing will

remain flexible, allowing the Company to respond to geological observations as drilling progresses.

Drilling at Bunker Hill will continue for as long as seasonal weather and operating conditions permit.

Sam Pazuki, Managing Director and CEO of AuMEGA, commented:

"Completing the first-ever drilling at the Isle aux Morts Granite is an important milestone for AuMEGA.

This program tested multiple geological concepts across the intrusive core, its margins and the

surrounding structural setting, while also advancing the new Early Bird gold target and extending our

work at Window Glass Hill.

We now look forward to receiving the assay results and integrating them with our geological,

geophysical and geochemical datasets to refine the next phase of drilling. In the meantime, the rig

has moved to Bunker Hill, where we are testing a pipeline of high-priority gold and polymetallic targets

across another underexplored part of our extensive land package. Following this drilling, we expect to

return to Cape Ray for additional drilling with the potential of drilling a much deeper hole into the Isle

aux Morts Granite."
