Anteros Identifies High-Grade Copper-Gold Targets at the
Strickland VMS Property, Newfoundland
St. John’s, Newfoundland and Labrador, May 21, 2025 – Anteros Metals Inc. (CSE:ANT) (“Anteros” or
the “Company”) is pleased to report results from recent assessment work at its 100% owned Strickland
VMS Property (“Strickland” or the “Property”) in southwestern Newfoundland. The work focused on
the digitization and interpretation of multi-element geochemical data from historic trenching,
advancing drill targeting efforts on this underexplored polymetallic volcanogenic massive sulphide
(“VMS”) system.
Prior to its public listing, Anteros commissioned the compilation, digitization, and 3D geological
modelling of the Strickland VMS system in 2023 and 2024. This foundational work established a strong
understanding of Property’s geology, alteration, and structure, and enhanced the understanding of
multiple mineralized zones along a 1.4 kilometre trend (Figure 1). Since going public, Anteros has
advanced the project through targeted follow-up, focusing on geochemical vectoring and priority zone
refinement. The 2025 program confirmed compelling indicators of feeder-style alteration and
mineralization in underexplored zones and highlighted several new high-priority exploration targets.
Mineralization Highlights:
• Feeder-style alteration and mineralization confirmed: Compilation of 95 multi-element assays
from 2012 trenching, integrated with historical drill data in 3D models, is helping to vector
toward the potential VMS core and optimize future drill targeting.
• Copper Zone: Now a high-priority target, with historical trench sampling returning up to 3.7%
Cu and 3.25 g/t Au over 1 metre (Cu-C1, Table 1), alongside elevated cobalt and intense
alteration – features consistent with VMS feeder conduits.
• Gold Zone: Historical trenching returned 1-metre intervals up to 3.2% Cu and 1.32 g/t Au (Au-
C1, Table 1), with alteration and elemental ratios indicating proximity to a hydrothermal center.
This zone has never been drill-tested.
• Main Zone and Main Extension: Historical trench samples demonstrate elevated Pb-Zn-Ag over
extended strike lengths, consistent with stratiform VMS-style mineralization.

“The presence of multiple, mineralized zones along an over 1 kilometre trend indicates a significant
VMS system,” said Trumbull Fisher, Anteros CEO. “Specifically, the underexplored feeder-style alteration
and high-grade gold-copper intervals of the Copper and Gold Zones have emerged as immediate
exploration priorities.”
Next Steps
Building on the promising results to date, Anteros is planning a focused exploration program that
includes:
• Field verification of historical trench and drill collar locations to validate spatial accuracy
• Integration of additional multi-element geochemistry into 3D models to refine and prioritize
drill targets
• Hyperspectral and induced polarization (“IP”) surveying to image alteration halos and sulphide
concentrations at depth
• Diamond drilling of the Copper and Gold Zones, which remain largely untested despite
returning high-grade trench results
About The Property
Strickland is held 100% by Anteros and is located approximately 85 kilometres south of Stephenville,
within the Exploits Subzone of the prolific Dunnage Zone in central Newfoundland – an area renowned
for hosting world-class VMS deposits. The Property hosts seven documented zones of copper (“Cu”),
lead (“Pb”), zinc (“Zn”), silver (“Ag”), gold (“Au”) mineralization along a 1.4 kilometre trend.
Mineralization at Strickland is interpreted to represent a bimodal-felsic (Kuroko-type) VMS system.
Documented sulphide mineralization includes sphalerite, chalcopyrite, galena, and pyrite in high-grade
polymetallic horizons—positioning the Property within the scope of Canada’s Critical Minerals Strategy.
In 1981, D.R. Prince of Falconbridge Nickel Mines Ltd. reported the following historical mineral
inventories:
• 260,000 tonnes at 195 g/t Ag and 5.25% combined Pb and Zn at the Main Zone,
• 15,000 tonnes at 480 g/t Ag and 2% combined Pb+Zn at the Silver Hill Zone, and
• 750,000 tonnes at 2% combined Pb+Zn at the Main Extension Zone

These estimates are considered historical in nature and were not prepared using current Canadian
Institute of Mining, Metallurgy and Petroleum (“CIM”) Definition Standards. A Qualified Person has not
completed sufficient work to classify the historical estimates as current mineral resources, and Anteros
is not treating them as current mineral resources. The Company considers these estimates relevant to
the extent that they indicate the presence of significant mineralization and support continued
exploration.

The reliability of the estimates is uncertain due to the age of the data, incomplete documentation of
estimation methods, and the lack of modern QA/QC protocols. The original report does not provide
specific cut-off grades, metal price assumptions, or a description of the estimation methodology. To
verify or upgrade these estimates to current standards, Anteros would need to complete field
validation of historic trench and drill collar locations, resample archived or in situ material using
modern analytical methods, apply current QA/QC protocols, and complete a compliant geological
model that supports estimation in accordance with CIM Definition Standards.
Since acquiring the Property in March 2022, Anteros has completed comprehensive digital compilation
and geological modelling of historical data including airborne and ground geophysics, geological
mapping, geochemistry, and over 7,000 metres of historical drilling and trenching.
