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

St. John's, Newfoundland and Labrador--(Newsfile Corp. - 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.
