Gladiator Completes Gravity Survey and
Identifies Multiple Large-Scale, Untested
Copper Skarn Targets at Little Chief
Vancouver, British Columbia--(Newsfile Corp. - July 2, 2025) -
Gladiator Metals Corp (TSXV: GLAD)
(OTCQB: GDTRF) (FSE: ZX7)
("
Gladiator
" or the "
Company
") is pleased to provide compelling
results from gravimetric geophysical fieldwork resulting in the identification of multiple, undrilled gravity
anomalies at the previously mined Little Chief Trend, Whitehorse Copper Project.
Multiple high-density anomalies have been identified potentially relating to untested copper-
gold skarn mineralization, including:
Valerie:
Prominent
2km long high-density, gravity anomaly
correlated with both a high
magnetic response from drone-borne aeromagnetics and coincident with mapped copper-gold
skarn mineralization on surface.
LC Footwall:
A
900m long untested, coincident gravity and magnetic high
with copper-gold
skarn mineralization observed on surface.
LC Gravity Offset:
An untested
400m long high-density, gravity anomaly
to the East of the
historical Little Chief pit.
Additional gravity anomalies detected in previously unexplored areas
proximal to the historic
Little Chief copper mine that produced >8.5Mt at 1.5% Cu and 0.75g/t Au

.
Shallow exploration drilling is planned to test these anomalies with
two diamond drill rigs to be
mobilized to the prospect areas
in the coming weeks
in conjunction with ongoing resource drilling
at the company's flagship Cowley Park prospect area.

Gladiator CEO Jason Bontempo commented:
"We are excited by the untested copper-gold skarn
exploration potential indicated by the recently completed gravity survey at Little Chief. This supports
Gladiator's belief that the Whitehorse Copper belt is a target-rich environment that is significantly
underexplored, away from areas of outcropping mineralization which were the focus of historical
exploration efforts.
Two diamond drill rigs will be mobilized in the coming weeks to focus on the discovery of new zones of
mineralization at the Little Chief trend as part of Gladiator's fully funded 2025 exploration program.
This forms part of Gladiator's overall strategy of extensive regional drilling to explore the full potential
of the 35km long, underexplored, Whitehorse Copper Belt whilst at the same time advancing Cowley
Park to maiden resource."
Little Chief Gravity Targets
Gladiator has received results for a recently completed gravimetric survey at the Little Chief Trend that
has highlighted multiple, high-density bodies potentially representing extensive bodies of untested and
previously unrecognized Copper-Gold skarn mineralization under thin cover (refer
to Figure 1 below).

The results of the gravity survey have been compiled with existing datasets and have identified
compelling, near-term drill targets which include:
Valerie:
A prominent 2km long gravity anomaly correlated with mapped copper-gold skarn
mineralization mapped on surface at the Valerie prospect. The target is mostly under thin till cover
and is easily accessible from the Copper Haul Road.
LC Footwall:
A distinct 900m long untested coincident gravity and magnetic high with copper-
gold skarn mineralization mapped on surface. Remarkably this target remains untested by
previous exploration efforts, despite being located proximal to historical mining operations in the
area (refer to Figure 2 below).

LC Gravity Offset:
A 400m high-density, sub-surface, untested anomaly to the East of the
historical Little Chief pit. Mineralized copper-gold skarn has been drilled to the north of this
anomaly, providing further encouragement.
As well as these identified high-density gravity anomalies, multiple further discrete additional anomalies
have been detected in previously unexplored areas proximal to the historic Little Chief copper mine that
produced >8.5Mt at 1.5% Cu and 0.75g/t Au (
Watson P.H., 1984 - The Whitehorse Copper Belt - A
Compilation. Yukon Geological Survey, Open File 1984-1
) These will also be subjected to further
surface exploration ahead of first pass drill planning.
Particularly encouraging is the observable coincidence between high-density gravity anomalies and
known mineralization at the Middle Chief and Big Chief targets, where near-surface magnetite-copper-
gold skarn mineralization has been defined over more than 600 metres of strike north of the historical
mining operations at Little Chief with historical results including (refer to the Company's
news release
dated January 18, 2024
, for details):
LCU-003:
53.56m @ 1.23% Cu from 88.54m
LCU-009:
49.83m @ 3.06% Cu from 70.26m
LCU-013
23.01m @ 2.07% Cu from 87.78m
LCU-017:
54.10m @ 2.05% Cu from 77.42m
LCU-023:
33.99m @ 2.10% Cu from 148.89m, Incl. 15.24m @ 3.26%Cu from 167.64m
LCU-151:
32.92m @ 2.08% Cu from 86.87m
This provides support for further exploration targeting undrilled high-density gravity anomalies in the
area.
Two diamond rigs will be mobilised to the Little Chief trend in the coming weeks with a focus on first
pass exploration of priority target areas.
FURTHER INFORMATION
In May 2025, Aurora Geosciences completed ground-based gravity surveys on behalf of Gladiator,
covering the Little Chief target area. The program was designed to assist in target definition and support
drill hole planning, particularly in areas of shallow till cover. The survey was conducted on 100m x 20m
survey spacings with areas of early interest closed to 50m x 20m spacing. Data was interpreted and
inverted by Southern Geosciences Ltd (Perth, Australia).
The gravity survey measures variations in the Earth's gravitational field to identify subsurface variations
in density. Copper skarn mineralization in the Whitehorse district has a significantly higher density than
surrounding country rock and so sub-surface anomalism provides information for first pass drilling to
define if high-density bodies that may represent areas of prospective mineralization.
Instrumentation used in the survey consists of two Scintrex gravimeters and two Leica RTK GPS
receivers.
EXPLORATION STRATEGY
The ongoing drilling at Cowley Park is part of a planned 29,000m drill program targeting high-grade
copper skarns throughout the Whitehorse Copper Belt before the end of Q4 2025. Drilling is designed
with the following objectives:
1 - Advancing Cowley Park to resource definition and expansion:
Cowley Resource Target:
Establish initial drilling framework for an inferred resource at Cowley
Park.
Cowley Exploration:
Targeting upside potential for further copper-skarn mineralization at Cowley
Park.
2 - Exploration drilling at:
Chiefs Trend:
Highlight further high-grade, near-term copper resource potential by testing near
historic mine exploration upside.
Best Chance:
Drill test of outcropping high-grade, magnetite-copper skarn mineralization and
broader widths of copper-silicate skarn and test continuity of mineralization between the Best
Chance and Arctic Chief prospects.
Arctic Chief:
Highlight continuity of high-grade near surface copper and gold mineralization for
future resource drilling.
Cub Trend Exploration:
Highlight continuity of high-grade, near surface, copper and gold
mineralization for future resource drilling.
Drilling will be supported by planned geophysical programs including Induced Polarization (ongoing),
Electromagnetic and Gravity surveys to help refine drill targeting in the prospect areas and highlight
undiscovered areas of exploration potential.
THE WHITEHORSE COPPER PROJECT
The Whitehorse Copper Project is an advanced-stage high grade copper (Cu), molybdenum (Mo), silver
(Ag) and gold (Au) skarn exploration project in the Yukon Territory, Canada.
Copper mineralization was first discovered in 1897 on the Whitehorse Copper Belt and comprises over
30 copper-related, primarily skarn occurrences covering an area of 35km long by 5 km wide on the
western margin of Whitehorse City, Yukon.
Exploration and mining development have been carried out intermittently since 1897 with the main
production era lasting between 1967and 1982 where production from primarily the Little Chief deposit
totalled 267,500,000 pounds copper, 225,000 ounces of gold and 2,838,000 ounces of silver from 11.1
million tons of mineralized material milled (Watson, 1984). The Whitehorse Copper Project is accessible
by numerous access roads and trails located within 2 km of the South Klondike Highway and the Alaska
Highway. An extensive network of historical gravel exploration and haul roads exists throughout the
project area, providing excellent access to the claim package. Access to existing electric power facilities
is available through the main Yukon power grid.
