Anteros Identifies a Near-Surface High-Grade Critical Mineral Target at the
Havens Steady VMS Deposit, Newfoundland
St. John’s, Newfoundland and Labrador, May 1, 2025 – Anteros Metals Inc. (CSE:ANT) (“Anteros” or
the “Company”) is pleased to announce the identification of a near-surface, high-grade, critical-metal-
bearing zone at its 100% owned, road-accessible Havens Steady VMS Property (“Havens Steady” or the
“Property”) in central Newfoundland. AI-assisted 3D modelling of historical drill data has highlighted
stacked lenses of zinc-lead-silver-copper mineralization near surface. This newly interpreted target
area, termed the NHC Zone, remains largely untested by historical drilling and will be a key focus of
upcoming exploration activities. Field validation and further targeting work are planned to support an
inaugural mineral resource estimate for the Property.
Located approximately 40 kilometres southeast of Buchans and 17 kilometres from the past-producing
Duck Pond Mine, Havens Steady hosts a laterally extensive polymetallic volcanogenic massive sulphide
(“VMS”) system. The latest modelling confirms a steeply southeast-dipping main mineralized zone
(“MMZ”) trending 057°, with over 700 metres of drilled strike and multiple open vectors along strike
and at depth. Within the MMZ, a shallow, relatively high-grade zone is modelled to exist (Figure 1).
NHC TARGET HIGHLIGHTS:
• Shallow High-Grade Zone – A near-surface, high-grade target interpreted from historical data
with limited prior drill testing (Table 1).
• Copper-Rich Feeder Zone – Historic drill intercepts, elevated Cu:Pb+Zn ratios, and silica-chlorite
alteration suggest a potential vent-proximal feeder.
• Shallow Infill Potential – Gaps in historical drill coverage within the MMZ, particularly in areas
with thin overburden, present cost-effective opportunities for delineating additional
mineralization and supporting future resource evaluation.
• Improved Surface Access – Recent timber harvesting has improved access to multiple target
areas, enabling inaugural trenching and low-cost grade verification in underexplored areas.
• Scalable System in a Proven Critical Mineral District – Havens Steady is situated within a
critical mineral belt with strong regional analogues, including past-producing VMS mines.

Anteros CEO Trumbull Fisher comments, “The identification of this shallow, high-grade zone adds
meaningful scale and near-term potential to the Havens Steady Property. With surface access recently
improved and multiple untested vectors emerging, we are well-positioned to advance this system
toward resource definition.”
NEXT STEPS
Anteros plans to undertake field validation and surface mapping in Q2 2025, followed by refinement of
drill targets for Phase I drilling, planned for Q3 2025. Priority targets include the NHC Zone and
northeast extensions of the MMZ. The Property is fully permitted for diamond drilling, and the
Company intends to leverage provincial critical mineral exploration grants to support 2025 work.
ELECTION OF DIRECTOR
In addition, the Company is pleased to announce that at its annual and special shareholder meeting
held on April 30, 2025 (the "Meeting"), Ms. Emily Halle was elected as a new director of the Company.
Ms. Halle is the Co-founder, Geologist, and Managing Director at Halle Geological Services Ltd, a
comprehensive exploration management and consulting company since 2008.
Mr. Wesley Keats did not stand for re-election at the Meeting, however, Mr. Keats will remain an
advisor to the Company. The Company would like to thank Mr. Keats for his contributions to the
Company and wishes him success in his future endeavour.
In connection with the election of Ms. Halle as a director of the Company, Ms. Halle was granted
300,000 stock options to purchase common shares of the Company exercisable at a price of $0.10 per
common share for a period of five (5) years. The common shares issuable upon exercise of the options
are subject to a four month hold period from the original date of grant.
ABOUT THE PROPERTY
Havens Steady lies within the Storm Brook Formation of the Red Cross Group in the Exploits Subzone of
the Dunnage Zone – a prolific metallogenic belt in central Newfoundland. The Property benefits from
existing road infrastructure and proximity to hydroelectric power. The region hosts world class VMS
deposits such as the past-producing Duck Pond Mine. The Company cautions that mineralization
hosted on adjacent and/or nearby properties is not necessarily indicative of mineralization on the
Property.
Since acquiring the Property in January 2024, Anteros has completed a comprehensive compilation of
historical data, which includes airborne EM, geochemical surveys, and over 15,000 metres of historical
drilling. Documented mineralization includes sphalerite, galena, chalcopyrite, and bornite in high-grade
polymetallic zones. The known system has a strike length of over a kilometre and remains open at
depth.
