Geologically consistent mineral deposit with a 1,000-meter strike length of Pb-Zn-Ag (±Cu-Au) mineralization
Road accessible and proximal to past-producing VMS mine-sites and infrastructure
Approximately 8,150 metres of historical drilling since 1986
Fully permitted for exploration diamond drilling from the Mineral Lands Division of Newfoundland and Labrador

ABOUT THE PROPERTY

The Property hosts a road-accessible Volcanogenic Massive Sulphide ("VMS") lead-zinc-silver ±copper-gold deposit located within the Central Mobile Belt of the Dunnage Zone, an established mining district in south-central Newfoundland, that is close to hydroelectric power (Figure 1). The region is underlain by sequences of Cambrian to Silurian volcanic and sedimentary rocks and related intrusive rocks.

The Property borders the Victoria Lake Supergroup, a complex assortment of several distinct volcanic sequences, some of which host world class VMS deposits. Notably, the past-producing Duck Pond VMS Mine, which had reserves of 4.078 million tonnes grading 3.29% Cu, 5.68% Zn, 59.3g/t Ag and 0.86g/t Au as well as additional inferred and measured 1.073 million tonnes of 3.04% Cu, 7.05% Zn, 71.2g/t Ag and 0.8g/t Au prior to mining in 2006 (Canadian Mining Journal, Aug 1, 2006). The Company cautions that mineralization hosted on adjacent and/or nearby properties is not necessarily indicative of mineralization that may be hosted on the Property.

Since acquiring the Property in January 2024, Anteros has performed comprehensive digital compilation of historical exploration data. Compilation confirmed that previous geophysical work, including airborne electromagnetics, identified multiple conductive anomalies consistent with the presence of sulfide mineralization. Additionally, historic drill programs have outlined multiple zones of high-grade lead, zinc, silver, and copper mineralization demonstrated by the presence of sphalerite and galena with bornite and chalcopyrite in copper-rich zones. The known deposit area has a strike length of at least 1,000 metres and historic drilling shows mineralization extending to over 800 metres below surface.

Anteros Metals Initiates Channel Sampling at Havens Steady Following Grant Confirmation and Exploration Permit Approval

Anteros Metals Inc. (CSE: ANT) ("Anteros" or the "Company") is pleased to announce the commencement of a trenching and channel sampling program at its wholly-owned, road-accessible Havens Steady VMS Property ("Havens Steady" or the "Property") in central Newfoundland. This milestone follows confirmation of a Junior Exploration Assistance ("JEA") grant, and receipt of a provincial permit authorizing ten mechanical trenches and four ground supported drill holes.

Work is now underway at the Main Mineralized Zone ("MMZ"), where recent grab sampling confirmed high-grade lead-zinc-silver mineralization. Channel sampling of existing outcrop exposure will generate inaugural grade over width data for the MMZ zone, and will be followed by mechanized trenching to expose bedrock across key areas of the MMZ in addition to the highly-prospective northeastern extension area. The channel and trenching program will result in high-confidence targets slated to be drilled in 2025.

Anteros Identifies High-Grade Copper-Gold Targets at the Strickland VMS Property, Newfoundland

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.

Anteros Identifies a Near-Surface High-Grade Critical Mineral Target at the Havens Steady VMS Deposit, Newfoundland

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).
