MTB Metals continues exploration at Southmore

Executive Summary

• MTB Metals announced the commencement of its 2025 fall exploration program on the Southmore property, highlighting several high‑grade historic intercepts and newly identified targets.
• Notable assay results include up to 13.6 % Cu, 6.2 g/t Au, 91 g/t Ag from the Mega Gossan zone and 82.3 g/t Ag, 0.4 g/t Au, 1.7 % Cu from the Magnetic Attraction skarn.
• The upcoming fieldwork will focus on the Horizon skarn and surrounding alteration zones, employing additional geological mapping, prospecting, and a 3‑D induced polarization (IP) survey.

Key Details

• Property Context: Southmore sits in BC’s Golden Triangle, within 8 km of the Galore Creek access road and near historic mines such as Eskay Creek, Galore Creek, and Shaft Creek.
• Historical Background: Acquired in 2019; prior work included mapping, soil/rock geochemistry, SkyTEM airborne survey, and 3‑D interpretation.
• Identified Targets & Assays:
• Mega Gossan zone – up to 13.6 % Cu, 6.2 g/t Au, 91 g/t Ag, 0.77 % Pb, 9.7 % Zn over a 1,300‑m surface trace.
• Magnetic Attraction skarn – magnetic/conductivity anomaly; assays up to 82.3 g/t Ag, 0.4 g/t Au, 1.7 % Cu, 6.0 % Zn over ≥100 m.
• Horizon skarn – historic sample: 106.9 g/t Au, 59 g/t Ag, 2.2 % Cu; trench/channel work returned 18.69 g/t Au, 15.3 g/t Ag, 0.52 % Cu over 3 m.
• Dundee skarns – assays up to 3.6 g/t Au, 10.8 % Cu, 4.5 % Zn.
• Additional alteration zones with up to 2,920 ppb Au mapped in the northern claim area.
• 2025 Fall Exploration Focus:
• Target: Horizon skarn and adjacent structures.
• Activities: Continued geological mapping, systematic prospecting, and a new 3‑D induced polarization (IP) survey to refine target definition.
• Qualified Person: Andrew Wilkins, P.Geo., project geologist (Lithos Geological Inc.) – NI 43‑101 qualified person for technical information.
