Anteros Metals Reports Assay Results from RM26-01 and Provides Exploration Update at the Seagull Critical Minerals Project, Ontario

Executive Summary
- Assay results from drill hole RM26‑01 at the Seagull Critical Minerals Project show multiple intervals with ≥1.5 g/t combined Pt+Pd, confirming PGE mineralization in the basal contact zone.
- Pressurized gas occurrences were observed in three holes (including historical WM01‑08), indicating a potential gas‑bearing system beneath the intrusion.
- The company plans to resume drilling on selected historic holes in late April–early May 2026 to further test PGE zones and evaluate the identified gas structures.
Key Details
- Hole RM26‑01 location: 35°67′46″ E, 54°32′23″ N (NAD83Z16), dip −87°, azimuth 180°.
- Weighted average results (0.5 g/t Pt+Pd cutoff):
- 7.25 m @ 587‑594.25 m – 1.58 g/t Pt+Pd (0.72 ppm Pt, 0.86 ppm Pd), 294 ppm Cu, 2,168 ppm Ni.
- 1.00 m @ 606.25‑607.25 m – 2.27 g/t Pt+Pd (1.02 ppm Pt, 1.25 ppm Pd), 1,660 ppm Cu, 2,080 ppm Ni.
- Higher‑grade subsets (1.0 g/t Pt+Pd cutoff):
- 3.00 m @ 591.25‑594.25 m – 2.26 g/t Pt+Pd.
-
1.00 m interval at 606.25‑607.25 m – 2.27 g/t Pt+Pd (same as above).
-
Gas observations:
- Historical hole WM01‑08 (2001) – sustained pressurized gas flow during drilling.
- RM26‑01 (2026) – pressurized gas at ~877 m (initial 37 kPa, 500 ppm CO₂); pressure declined to negligible before sampling. Hole sealed for monitoring.
-
Extension of WM00‑05 to 900 m – minor anomalous CO detected at ~882 m in Quetico metasedimentary rocks; non‑sustained, no measurable pressure.
-
Future drilling plan: Resume work on selected historic holes (late April–early May 2026) using existing infrastructure to target basal PGE zones and gas‑bearing structures cost‑effectively.
Notable Quotes
“The RM26-01 assays confirm PGE mineralization in the basal contact and support continuity with historical intersections, strengthening the critical minerals potential at Seagull,” said Trumbull Fisher, CEO of Anteros Metals Inc.
“The observation of gas indications in three holes to date… is encouraging and highlights the presence of a gas system that merits continued investigation.”
