HM Exploration Acquires High Grade Copper VMS Project in
Newfoundland
Vancouver, September 29, 2025 – HM Exploration Corp. (“HM Exploration” or “HM” or the “Company”)
(CSE:HM) is pleased to announce that it has entered into an option agreement (the “Agreement”) dated
September 25, 2025 with Great Atlantic Resources Corp. (TSX-V:GR) (the “Optionor”) to acquire a 100%
interest in the the Pilley’s Island Copper Project (the “ Project”), located in Newfoundland, Canada (the
“Acquisition”).
Highlights:
• Multiple VMS-style targets identified, including the Clifford Jones / Fragmental Zones , which
returned channel sample grades up to 15.40% Zn, 6.60% Pb, 4.66% Cu, and 111.5 0 g/t Ag over
1.05m and grab samples up to 40.8% Zn, 20.0% Pb, 8.36% Cu, 148.1 g/t Ag and 2.28 g/t Au.
• Historic drill intercepts include:
o 82.47 - 85.21m: 2.74m of 6.40% Cu, 0.46% Zn, 11.28 g/t Ag, 0.85 g/t Au (PI-89-05)
▪ Including: 82.47 - 84.54m: 2.07m of 7.79% Cu, 13.40 g/t Ag, 1.05 g/t Au
o 50.75 – 53.12m: 2.40 m of 0.94% Cu, 12.45% Zn, 3.17 g/t Au, 5.51% Pb (Hole 42)
o 5.49m of 1.40% Cu, 0.76% Pb, 7.32% Zn, 20.53 g/t Ag (BBF-54)
o 5.33m of 1.03% Cu, 0.19% Pb, 1.79% Zn, 6.84 g/t Ag, 0.31 g/t Au (BBF-22)
• Excellent infrastructure and access: Project is road-accessible located ~25 km east of Springdale,
within an established mining friendly district that also hosts the Buchans, Ming, and Rambler past
producing mines. The Project is situated ~150 kilometers from the Pine Cove Mill and Port by way
of major roads.
• The Project hosts the historic Pilley’s Island Mine, which produced ~450,000 tonnes of ore in the
late 1800s, and carries reported (non -NI 43-101 compliant) reserves of 1.16 Mt of 1.23% Cu*
(Grimley, 1968).
• Historic work mainly targeted shallow showings, with deeper and along -strike potential left
largely untested. Geophysical anomalies were recognized but never systematically explored with
modern methods.
• HM plans to continue to compile the over 100 years of inherited geological data to establish a
systematic exploration program to begin late 2025.
* The reported reserves are historical in nature and are not considered current mineral resources or mineral reserves as defined by NI 43-101. The
Company has not done sufficient work to classify these estimates as current, and a qualified person has not verified them.
Nicholas Rodway, P .Geo., President & CEO of HM Exploration, commented:
"With the Pilley’s Island Project now in hand, we are stepping into a high -grade VMS copper camp with
exceptional upside potential. The Project benefits from a strong mining history, multimillion dollars of
exploration work inherited, excellent infrastructure, and nearby producing operations —factors that
position HM Exploration to unlock meaningful value for shareholders."

About the Project
The Project consists of eight (8) mineral licenses encompassing a total land area of 12.25km2 and is located
in Notre Dame Bay, Newfoundland – Canada. The Project has a long history of mining and exploration
dating back to the late 1800’s when the Pilley’s Island Pyrite Company Ltd. produced approximately
450,000 tonnes of massive pyritic ore from the Pilley’s Island Mine – Old Mines (after Kerr, 1996).
The Project is road accessible and situated ~25 kilometers east of the town of Springdale , approximately
210 kilometers from the town of Gander and ~150 kilometers from the Pine Cove Mill and Port by way of
major roads.
The Pilley’s Island Project hosts a cluster of Volcanogenic Massive Sulfide (VMS) systems and prospects
with demonstrated high -grade Zn -Pb-Cu-Ag intersections. Mineralization is typical bimodal -felsic VMS,
with both massive sulfide and sulfide-clast breccias (Thurlow, 2001). The geological setting is directly
analogous to the Buchans camp (Thurlow, 1996), and the presence of sulfide -clast breccias is a strong
vector toward proximal massive sulfide lenses. Deep drilling has confirmed a large hydrothermal system
with significant sulfide development. Further systematic exploration, particularly at depth and along strike
of the Clifford Jones/Fragmental Zones is currently being planned.
Many historic programs focused on shallow high -grade showings; deeper targets were only sporadically
tested (Brinex, 1967). The Bull Road and Fragmental Zones were not systematically drilled along strike or
down plunge (Hum, 1983). Geophysical anomalies adjacent to known zones were not followed up with
drilling (Altius, 2001). Jasper Zone intersections (deep sulfides) were recognized but not fully explored with
modern vectoring techniques (Altius/Inmet, 2003).

Geology & Mineralization
The Project is located within the Notre Dame Subzone of the Dunnage Tectonostratigraphic Zone. Of note,
most of the Project is underlain by Ordovician submarine volcanic rocks of the Roberts Arm Group which
is regionally identified as part of a mature arc sequence referred to as the Buchans-Roberts Arm Belt that
also hosts the historic Buchan’s mine (after Dunning et. Al., 1987 ). Mineralization occurs as low grade
(Spencer’s Dock); medium grade (Old Mines); and high grade (3B-Zone/Clifford Jones) deposits that are of
both sub -seafloor replacement and exhalative varieties. The deposits are often flanked by extensive
chlorite, sericite, silica, K-feldspar and epidote alteration often observed in bimodal-felsic VMS systems.
The Spencer's Dock area displays sericite/silica alteration that generally increases in intensity near
mineralized zones, while the 3B/ Old Mine areas display sericite/silica alteration that is abundant but less
widespread and is more intense when proximal to mineralized zones (after Kerr, 1996).
Volcanogenic Massive Sulfide deposits are a globally significant source of copper, zinc, lead, silver, and
gold. The Project’s geology shares key characteristics with known VMS districts in Newfoundland, including
the past producing Buchans, Ming and Rambler Mines supporting the explo ration potential of the
property.
From north to south the Project is underlain by:

Roberts Arm Group – Middle Ordovician
The Roberts Arm Group, which hosts known mineralization, is complexly faulted and consist of an older
tholeiitic terrane overlain by more calc-alkaline thrust slices. It is suggested that it represents an evolution
from tholeiitic, back arc basalts to calc-alkaline intermediate to felsic volcanics deposited at about the time
of continental collision in a neritic to littoral environment (after Bostock – 1988).

CSE: HM
The Bull Road – Clifford Jones Zone / Fragmental showings are a re -sedimented, polylithic breccia
containing abundant high -grade Zn -Pb-Cu sulfide clasts similar to the breccia ores at Buchan’s. The
showings, are significant and suggests the potential for an ore -grade deposit source (after Consolidated
Morrison Ltd., 1979).

*The Project hosts the historic Pilley’s Island Mine, which operated during the 1890s and early 1900s. The Newfoundland and
Labrador Department of Natural Resources reports historic estimated proven reserves of 1.159 million tonnes grading 1.23% Cu
(referencing Grimley, 1968 as the source) in their Mineral Occurrence Database. These historical estimates of reserves are not
reliable. The historical estimates are only relevant to the extent of identifying an area on the Project for research and pos sible
future exploration. The key assumptions, parameters, and methods used to prepare the historical estimates are not known. A
qualified person has not done sufficient work to classify the historical estimates as current resources or current reserves. A
qualified person would need to complete sufficient work following CIM Best Practice Guidelines to upgrade or verify the historical
estimates as current mineral resources or mineral reserves. This would almost certainly require additional exploration in the way
of diamond drilling, trenching and / or underground work and corresponding sampling all of which must follow CIM Exploration
Best Practice Guidelines. HM Exploration does not treat the historical estimates for the historic Pilley’s Island Mine as current
mineral resources or mineral reserves. The historical ‘proven reserves’ reported by Grimley (1968) do not conform to the current
CIM Definition Standards for a ‘Proven Mineral Reserve,’ and should not be treated as such.
