Edmonton, Alberta--(Newsfile Corp. - September 23, 2024) -
AuMEGA Metals Ltd
(formerly Matador
Mining Ltd)
(ASX: AAM) (TSXV: AUM) (OTCQB: AUMMF)
("AuMEGA" or "the Company") is pleased
to report initial high-grade assay results from prospecting from the Company's 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:
"Aligned with our strategy to define and advance Greenfield exploration targets along the highly
prospective, multi-million-ounce Cape Ray-Valentine Lake Shear Zone, we are highly encouraged by
initial assays from our recent limited prospecting activities at Bunker Hill.
"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. Previous historic prospecting and sampling,
supported by recent programs conducted by the Company, has revealed the highest-grade gold, copper
and silver samples anywhere within our portfolio. This summer, we have carried out a limited prospecting
program in an area identified as being highly prospective during the Company's July 2024 Technical
Workshop.
"Initial results received from the prospecting program have revealed significant high-grade copper from
two outcropping vein samples in the prospective area of interest. These results align well with the historic
samples collected, which included significant copper samples with grades ranging from 40% to 57%
copper (float) and several high-grade gold and silver samples with peak samples of 17.05 g/t gold (float)
and 407.5 g/t silver (float), respectively.
"In addition to this limited prospecting program at Bunker Hill, the Company has completed a till
geochemistry survey in the same area as the prospecting with assays pending. We have also just
completed a till program over the western portion of Bunker Hill and have completed a high-resolution
airborne magnetic survey over the entire Bunker Hill area, to fill in a critical gap in the detailed magnetic
data over our CRSZ tenement package, which is now being processed.
"As additional results are received, we will analyse the data and establish next steps for a more
comprehensive exploration program at Bunker Hill with a high likelihood of future RC and diamond
drilling."

Prospecting Program and Results
During the Company's 2024 Technical Workshop
1
completed in early July 2024, the Bunker Hill Project
was identified as a priority area based on highly prospective geological features, a unique geological
setting along the CRSZ, and prominence of historic high-grade gold, silver and copper samples,
including the highest grade samples ever collected from the Company's portfolio of tenements
2
.
A limited initial prospecting and sampling campaign over the eastern portion of Bunker Hill conducted
this summer aimed to identify outcropping geology and confirm historically documented showings and
high-grade mineralisation. The Company also collected litho-geochemical samples and gathered
preliminary structural information to build a mineralisation, geological and structural framework of the
area.
The Bunker Hill Project area is located along a unique east-west portion of the CRSZ (Figure 2). This
structural orientation is anomalous to the main northeast-southwest trend of most geological structures in
Newfoundland. This structurally oblique zone is considered potentially favourable for the creation of
dilation zones, which allow for the ingress of mineralising fluids and deposit formation. The Company
also confirmed the presence of two large scale intrusive units being the Cape Ray Fault Gabbro and the
Nitty Gritty Granite.
The Nitty Gritty Granite offers important rheological conditions permissive for economic gold
mineralisation. Rigid granite blocks of this nature can often provide for a stark competency contrast
when intruding ductile rocks such as the sedimentary lithologies observed adjacent in the Bunker Hill
area, with intense fracturing during structural deformation allowing the significant ingress of mineralising
fluids. A local example of a gold deposit of this style is Calibre Mining's Valentine Project (five million
plus ounces of gold) along strike to the north-east.
First pass prospecting of the Nitty Gritty Granite confirmed positive indications of potentially economic
mineralisation with highlights including:
Sample MR002477 (outcrop) contained 17.2% copper, 16.9 g/t silver, 0.41 g/t gold, 167 ppm
bismuth and 5.37 ppm tellurium; and
Sample MR002478 (outcrop) contained 12.4% copper, 19.1 g/t silver, 0.56 g/t gold, 1119 ppm
bismuth and 9.98 ppm tellurium.
Many of the historic high-grade copper samples collected at Bunker Hill along with these recently
collected high-grade copper samples, fall within or adjacent to the Nitty Gritty Granite. The chalcocite-
malachite (MR002477) and chalcopyrite-bornite (MR002478) bearing samples are also associated with
gold, silver, tellurium and bismuth (Figure 3).
Other minerals observed during the recent prospecting campaign include fluorite and iron oxides
(hematite), both indicative of either potential intrusive or porphyry-related mineralisation. From review of
the historical data and recent prospecting results, the Company has identified an area of anomalous
copper-gold-silver mineralisation to be nearly one kilometre across strike (Figure 4). The Company is
currently assessing the potential for a porphyry-related mineralised system.

Historic Overview
The first significant discovery of mineralisation at Bunker Hill was by RIOCANEX in 1980 which
discovered an outcropping set of sulphide-bearing quartz veins containing up to 0.5 g/t gold, 20.6 g/t
silver, and 17.9% copper. Approximately 500 metres from the original RIOCANEX showing, Noranda
and Andina (Mercator) sampled multi-gram gold-bearing float samples containing up to 17.05 g/t gold
which have not yet been sourced (Figure 4). Silver is equally anomalous in the vicinity with assays up to
407.5 g/t in float (Figure 4).
Supplementary geochemical surveys identified large anomalous pathfinder trends in soils, highlighted by
a strong silver, copper, lead and zinc association. These pathfinder elements have known gold
associations along the CRSZ, however, this historical sampling was never assayed for gold due to the
primary focus on base metal sulphide mineralisation at that time by Noranda.
In the early 2000's, Cornerstone followed up with some anomalous grab samples collected at the eastern
edge of Bunker Hill recording up to 18.67 g/t gold with corresponding pathfinder elements up to 35.3 g/t
silver and 1.6% copper (Figure 2). In the 2010's, Benton Resources followed up on this work, further
confirming the presence of anomalous gold at the western portion of the Bunker Hill project area.
AuMEGA confirmed the historical outcrops by resampling during its 2022 prospecting campaign

.
In 2011, Marathon Gold also completed a prospecting program at the eastern edge of Bunker Hill which
was complemented by a VTEM survey in 2012. Marathon Gold sampled outcropping geology containing
gold, silver, and copper up to 0.898 g/t gold, 34.1 g/t silver, and 57% copper respectively (Figure 2 and
Figure 4). For comprehensive summary of historical information, refer to "Balanced Reporting' in
Appendix 2.

Next Steps
The Company is awaiting assays from its ongoing till program on the western portion of Bunker Hill. The
airborne magnetic survey is expected to be completed soon with preliminary data to follow shortly
thereafter.
The Company will analyse all data received from its 2024 program and based on these results and the
analysis, will develop future work plans that could involve RC winter drilling.
