AuMEGA High Resolution Magnetics Reveals Significant Geological Structures at Bunker Hill
AuMEGA High Resolution Magnetics Reveals
Significant Geological Structures at Bunker
Hill
Key Highlights
High-resolution airborne magnetic and Very Low Frequency Electromagnetic ("VLF") geophysical
survey completed over Bunker Hill, covering an area of approximately 170 km
2
consisting of 3,140
line-kilometres.
Preliminary magnetic data received with finalisation underway and expected before the end of the
year.
The survey reveals significant geological complexity across the entire 25-kilometre strike length of
Bunker Hill with data materially changing the Company's understanding of the prospective area.
Geological structures align with the recent and historic significant geochemical and prospecting
samples that contained very high-grade copper, gold and silver samples

Edmonton, Alberta--(Newsfile Corp. - October 15, 2024) -
AuMEGA Metals Ltd (ASX: AAM) (TSXV:
AUM) (OTCQB: AUMMF)
(formerly Matador Mining Ltd) ("AuMEGA" or "the Company") is pleased to
report the preliminary results of the recently completed high-resolution, airborne magnetic and VLF
survey over the entire Bunker Hill Project, located along the Cape Ray Shear Zone ("CRSZ") in
Newfoundland and Labrador, Canada.
AuMEGA Metal's Managing Director and CEO, Sam Pazuki commented:
"We are encouraged by the preliminary results received from the high-resolution airborne magnetic
survey that we have recently completed over our highly prospective, vastly underexplored Bunker Hill
Project. Initial survey results have revealed significant structural complexity highlighting the CRSZ while
also exposing major second and third order faults throughout the entire property.
"Our Bunker Hill Project represents 25 kilometres of continuous strike of a localised unique east-west
orientation directly adjacent to the east of our Malachite Project. Much of the area is covered with
overburden with very little surface bedrock exposure. What is striking about the Bunker Hill area is that
sampling to-date from limited outcrop has delivered some of the highest-grade copper, silver, and gold
samples anywhere within our portfolio. These high-grade samples are hosted within the Billiards Brook
Group sediments, and Cape Ray Fault Gabbro and within dominantly vein-hosted mineralisation. This
includes outcropping copper samples grading up to 25%, copper float samples grading up to 57%,
outcropping silver samples grading up to 44.5 g/t, silver float samples grading up to 407.5 g/t and gold
outcropping
samples grading up to 17.0 g/t.
"Overlaying the airborne magnetic survey results to these high-grade samples further supports our belief
that the Bunker Hill mineralisation is associated with intrusive-style mineralisation and the project
appears to be similarly structured to Calibre Mining's Valentine Project, which currently hosts a five
million ounce gold resource. The magnetics have also shown several jogs along the main CRSZ. This is
an important feature when comparing it to the Valentine Project, where each of the deposits in that
project are located specifically in the similarly structured jogs.
"We will continue to finalise the geophysical data received from the airborne survey and we are in the
process of defining our 2025 exploration plans, including our specific plans to further define the
significant potential that we see at Bunker Hill.
Assay results are also still pending from the Bunker Hill
and Intersection summer till survey programs, which we expect in the near-term along with assays from
the second phase of diamond drilling at Malachite that are expected in November 2024."

Airborne Magnetic Survey Overview
In 2021, the Company completed a high-resolution, airborne magnetic survey over a 44 kilometre stretch
from the Cape Ray and Isle Aux Morts Projects to the boundary limit of the Malachite Project
2
. This year,
the Company continued the high-resolution airborne geophysical survey from Malachite over the Bunker
Hill area, collecting a dataset of magnetic, VLF-EM and radiometric data.
This survey consisted of 3,142 line-kilometres over 25 kilometres of strike flown across Bunker Hill for a
total of approximately 170 km
2
of coverage. Data was acquired at 60-metre line spacing with a sensor
height of 30 metres.

Preliminary Airborne Survey Results
The preliminary data from the airborne geophysical survey has revealed significant structural complexity
and further confirms Bunker Hill as a high-priority Greenfields target for the Company. The entire project
area is structurally unique in the CRSZ corridor anomaly, given its east-west orientation and the
geophysical data demonstrates that the Bunker Hill structural domain is favourable to host large dilation
zones permissive for the ingress of mineralising fluids.
This is observed through the preservation of the thickened Billiards Brook Formation (type equivalent of
the Windsor Point Group - host to Central Zone, Isle aux Morts and Big Pond Deposits
3
) and intrusive
units such as the Nitty Gritty Granite that have intruded within the sedimentary package and become
entrained within the CRSZ. Recent outcropping results grading up to 17% copper and 19.1 g/t silver from
the Nitty Gritty Granite area further demonstrates the prospectivity of the target. These intrusive units that
have become entrained within the shear zone act as a brittle host, breaking apart and allowing the influx
of mineralising fluids. The area has striking similarities to Calibre's Valentine Project deposits, which are
located on the same structure 80 kilometres away to the northeast.
Large zones of a complex fault mosaic are also observed. These zones consist of major second and
third order splays that are discordant to the regional geology and are observed cutting through
historically mapped units favourable for gold mineralisation such as the iron-rich Cape Ray Fault Gabbro
and the Nitty Gritty Granite. An example of this is the Bunker Hill West Target (see Figure 2) where
previous prospecting and mapping results have identified the presence of a mafic unit that is cut by a
major second order structure with the spatial correlation to gold mineralisation with samples upwards of
18.9 g/t gold
4
.
Furthermore, the Billiards Brook Formation, which appears similar to the Windsor Point Group (current
host of the Company's gold mineral resource), is observed to be upwards of two kilometres thick,
representing the thickest occurrence outside of the Company's Central Zone, nearly 50 kilometres away
to the southwest.
Next Steps
The Company is expecting the final high-resolution magnetic survey results before the end of the year.
The Company will complete a detailed structural analysis and magnetic inversion with the recently
received data and will include all data collected to update its targeting matrix to re-rank its several dozen
exploration targets within the portfolio.
The Company is awaiting assay results from the Bunker Hill and Intersection till survey program as well
as diamond drill results from the second phase at Malachite. This data will help inform the Company as
to the next steps of its exploration program.

AuMEGA Metals Ltd
(ASX: AAM) (TSXV: AUM) (OTCQB: AUMMF)
is utilising best-in-class
exploration to explore on its district scale land package that spans 110 kilometers along the Cape Ray
Shear Zone, a significant under-explored geological feature recognised as Newfoundland, Canada's
largest identified gold structure. This zone currently hosts Calibre Mining's Valentine Gold Project, which
is the region's largest gold deposit (+5 million ounces), along with AuMEGA's expanding Mineral
Resource.
The Company is supported by a diverse shareholder registry of prominent global institutional investors,
and strategic investment from B2Gold Corp, a leading, multi-million-ounce a year gold producer.
Additionally, AuMEGA holds a 27-kilometer stretch of the highly prospective Hermitage Flexure and has
also secured an Option Agreement for the Blue Cove Copper Project in southeastern Newfoundland,
which exhibits strong potential for copper and other base metals.
AuMEGA's Cape Ray Shear Zone hosts several dozen high potential targets along with its existing
defined gold Mineral Resource of 6.1 million tonnes of ore grading an average of 2.25 g/t, totaling
450,000 ounces of Indicated Resources, and 3.4 million tonnes of ore grading an average of 1.44 g/t,
totaling 160,000 ounces in Inferred Resources
