Metalsource Mining identifies high-priority drill targets across 2.4 km at Silver Hill

Newly identified targets exhibit geophysical characteristics analogous to the Company's successful drilling, supporting accelerated exploration of a growing polymetallic system that remains open along strike, down dip and beyond the historic mine footprint. Vancouver, British Columbia--(Newsfile Corp. - July 16, 2026) - Metalsource Mining Inc. (CSE: MSM) (OTCQB: MSMMF) (FSE: E9Z) ("Metalsource" or the "Company") is pleased to announce the results of a recently completed induced polarization ("IP") survey designed to identify drill targets on strike from the historic Silver Hill mine. The survey identified approximately 2.4 kilometres of prospective strike length across two primary target areas, including a continuous 1.8 kilometre anomaly in the southern portion of the project area, in the immediate vicinity of Silver Hill, and an additional 600 metre IP anomaly in the northeast corner of the property.

These IP data and recent drilling results continue to validate Metalsource's exploration thesis that mineralization remains open in all directions, and there are significant opportunities to add scale to the mineralization discovered thus far through on strike and down dip exploration drilling. Key Highlights Phase 2 IP survey identifies approximately 2.4 kilometres of prospective target areas across the Silver Hill district. High priority drill targets display geophysical characteristics analogous to the mineralized corridor defined by recent drilling.

Targets remain open north and south of the historic mine , significantly expanding the Company's exploration pipeline. Results strengthen management's evolving geological model that Silver Hill may comprise multiple mineralized occurrences rather than a single historic deposit. Company advancing plans to increase drilling capacity to simultaneously expand known mineralization and systema
