Anteros Metals Reports Exploration and Drilling Results At Seagull, Havens Steady, Knob Lake and Strickland Properties Anteros Metals Inc. has completed diamond drilling at the Seagull Critical Minerals Project, with interpretation and target refinement underway. New PGE assay results have been received from selected deeper drill core intervals. Physical rock property measurements are being incorporated into a constrained geophysical inversion model. Monitoring continues for pressure recharge and gas accumulation on WM00-05EXT and RM26-01. Trenching and channel sampling are underway to test the interpreted bedrock source of high-grade copper-gold-silver float at the Havens Steady VMS property. Ongoing evaluation of advancement opportunities is taking place at the Strickland VMS property. At the Seagull Project, the diamond drill rig has been demobilized with the completion of drill hole WM00-05EXT to a final depth of 1,449m. The recent drill program has confirmed platinum group element mineralization within the Seagull intrusive complex, in addition to previously reported anomalous hydrogen, nitrogen and carbon dioxide gases. Assay results from selected drill core intervals in WM08-27EXT have been received from ALS Global with sample preparation completed in Thunder Bay and sample analyses in Vancouver. Drill hole WM08-27EXT located at 356994mE and 5432455mN (NAD83Z16) was drilled at a dip of minus 90 degrees with an azimuth of 180 degrees. The drill hole was a continuation of a historical hole that had been stopped at 600m. Drill hole was deepened to 1,200m with basal intrusive contact intersected at 692.9m. The drill hole intersected orthomagmatic sulphide mineralization in the basal cumulate sequence of the Seagull intrusion, returning up to 0.558 g/t combined platinum and palladium (0.254 ppm Pt and 0.304 ppm Pd) over 1.0 metre from 643.0 to 644.0 metres, including 290 ppm copper and 1,655 ppm nickel. The mineralized intersection is true width. Analysis for platinum group elements was completed by ALS Global using PGM-ICP24 (50-gram fire assay with ICP-AES finish) method, and base metals using ME-ICP61 (four-acid digestion with ICP-AES finish). Quality assurance/quality control included inserted standards and blanks, which performed within acceptable limits. The Company is continuing the collection of physical rock property measurements comprising magnetic susceptibility, density and seismic wave velocities from core obtained in Phase 1 and Phase 2 drilling programs. This data will be incorporated into the geophysical inversion workflow to generate a constrained inversion model. This work is expected to improve the resolution and reliability of subsurface interpretations and provide a more robust understanding of the geological controls associated with critical mineral potential and previously reported gas observations at Seagull. The updated model will integrate drilling, geophysical data and rock property measurements collected during the Company's exploration activities and is expected to assist in refining exploration targets within the Project area. The Company continues to monitor drill holes WM00-05EXT and RM26-01 for evidence of pressure recharge and gas accumulation while evaluating future exploration opportunities. The integration of measured rock properties into the inversion process represents a significant technical advancement and is expected to further constrain the Company's geological model. Trenching and channel sampling activities are now underway at its 100%-owned Havens Steady Polymetallic VMS property located in central Newfoundland. Havens Steady covers a laterally extensive polymetallic zinc-lead-copper-silver-gold volcanogenic massive sulphide system within the Storm Brook Formation of the Red Cross Group in the Exploits Subzone. Havens Steady is located approximately 40 kilometres southeast of Buchans and benefits from road infrastructure and nearby hydropower. The current program is focused on a high-priority copper-gold-silver target identified during the Company’s 2025 field program, where prospecting returned grab sample grades of up to 2.17% copper, 21.3 g/t silver and 0.22 g/t gold from angular mineralized float located approximately 200 metres northeast of the Main Mineralized Zone. Grab samples are selective by nature and may not be representative of mineralization at Havens Steady. The angular nature of the mineralized float suggests a nearby bedrock source and supports the Company’s interpretation that additional mineralized zones may exist outside the currently defined Main Mineralized Zone. The target area occurs within a prospective corridor identified by historical copper-in-soil anomalies and coincident geophysical features that have received limited modern follow-up exploration. Since acquiring Havens Steady in January 2024, Anteros has compiled and digitized extensive historical exploration datasets, including drilling, geophysical surveys and geochemical surveys completed by previous operators. Historical exploration identified multiple zones of polymetallic mineralization and demonstrated the presence of a large hydrothermal system. In 2025, the Company completed geological modelling, field validation and prospecting programs that confirmed historical exploration data and led to the discovery of high-grade copper-gold-silver mineralization in a previously untested area northeast of the Main Mineralized Zone. More recently, the Company completed preliminary trenching and channel sampling at the Main Mineralized Zone that confirmed mineralization at surface and expanded the Company’s understanding of exploration potential at Havens Steady. The current trenching and channel sampling program is designed to expose bedrock beneath shallow overburden, identify the potential bedrock source of the angular mineralized float, collect representative channel samples where mineralization is exposed, and refine targets for future drilling. Historical drilling and recent geological modelling indicate a mineralized corridor extending approximately 700 metres along strike, with exploration potential remaining both along strike and at depth. The Company believes that the combination of a historically defined VMS system, recent surface discoveries and multiple untested exploration targets supports the continued advancement of Havens Steady. Results from the current program will be incorporated into the Company’s evolving geological model and used to guide future exploration and drill targeting. The Company continues to evaluate opportunities to advance its 100%-owned Strickland property in southwestern Newfoundland. Announcement • Jun 17
Anteros Metals Inc Announces Trenching and Channel Sampling Program At Havens Steady VMS Property in Newfoundland Anteros Metals Inc. announced plans to commence a strategic trenching and channel sampling program at its 100%-owned Havens Steady Polymetallic VMS Project located in central Newfoundland. The trenching and channel sampling program will focus on a high-priority copper-gold-silver target identified during the Company's 2025 field program where prospecting uncovered angular float returning grab sample grades up to 2.17% copper, 21.3 g/t silver and 0.22 g/t gold from a previously untested area located approximately 200 metres northeast of the Main Mineralized Zone. The target area occurs within a prospective corridor identified by historical copper-in-soil anomalies and coincident geophysical features that have received limited modern follow-up exploration. The upcoming program is designed to expose and evaluate the potential bedrock source of the angular mineralized float and assess its relationship to the Main Mineralized Zone and the broader Havens Steady volcanogenic massive sulphide system. The program is fully funded and permitted, scheduled to commence early summer 2026, and is designed to expose and sample a potential bedrock source of previously reported copper-gold-silver mineralization discovered northeast of the Main Mineralized Zone. Recent field programs confirmed historical mineralization at surface and identified a new copper-rich target area outside the historically drilled footprint. Approximately 8,000 metres of historical drilling completed by previous operators outlined a significant polymetallic VMS system on the property including historical drill hole intercepts of broad zones of polymetallic mineralization, including 7.0 metres grading 0.5% Cu, 1.26% Pb, 4.36% Zn, 29 g/t Ag, and 1.0 g/t Au from drill hole HS-88-3 drilled in 1988, and historical drill hole intercepts of higher-grade mineralization, including 2.72 metres grading 2.1% Cu, 3.6% Pb, 6.2% Zn, 56 g/t Ag, and 1.8 g/t Au from drill hole HS09-18 drilled in 2009. Results are expected to refine future drill targeting and advance evaluation of the broader Havens Steady mineralized corridor. Announcement • May 25
