Silverco Mining Commences 30,000-Meter
2026 Drill Program at Cusi, Targeting Massive
Step-Out Potential and Regional Blue-Sky
Prospects
Vancouver, British Columbia--(Newsfile Corp. - March 17, 2026) - Silverco Mining Ltd. (TSXV:
SICO) ("Silverco" or the "Company") is pleased to announce the commencement of its fully funded,
30,000-meter 2026 exploration program at its 100% owned Cusi Mine in Mexico. While a portion of the
program will support operational restart preparation, a major focus of the campaign is aimed at
aggressive resource expansion and testing high potential exploration targets across the property. The
program will utilize both surface and underground rigs, split approximately evenly between the two.
2026 Exploration Program Highlights – Focus on Upside Potential:
San Juan Connectivity and Major Cusi Fault Extension:
Surface drilling is targeting a
massive, near 600-meter step-out to connect highly successful 2025 intercepts with historical
drilling. This targets a newly identified downthrown mineralized block representing the eastern
continuation of the San Juan vein across the Cusi fault.
San Miguel Blue-Sky Expansion:
Surface drilling is designed to aggressively test the lateral
and vertical limits of Cusi's cornerstone deposit, pushing beyond the known mineralization
footprint.
Regional Exploration Prospects:
Dedicated meterage is allocated to test additional high-
priority, unexplored regional targets across the property, alongside potential unlocked through
claim consolidation.
Near-Term Resource Growth at Promontorio:
Underground drilling will target near-term vein
extensions for resource expansion while simultaneously optimizing mine planning to reduce initial
development requirements.
Mark Ayranto, CEO of Silverco, commented
:
"This fully funded exploration program drives a core dual strategy. We remain very focused on
restarting operations at Cusi in the second half of 2026 while simultaneously exploring highly
prospective, near mine, targets that have the potential for game changing upside at Cusi."
San Juan – Unlocking a Massive Extension Across the Cusi Fault
The most significant blue-sky potential in the 2026 program lies in exploring a major extension across
the Cusi fault. During the 2025 campaign, Silverco successfully intercepted 6.8 metres grading 255 g/t
AgEq in drillhole CU-25-59 (
released in February 26 2026 news release
), which followed up on an
historical intercept of 4.3 metres grading 472 g/t AgEq in drillhole DC21B955.
These results represent a near 600-meter step-out from the main San Juan ore body, an area that
remains largely outside the recent Mineral Resource Estimate update. Geologically interpreted as the
continuation of the San Juan vein to the east of the Cusi fault, the 2026 program aims to test this newly
identified downthrown mineralized block to prove out a potentially massive continuation of the main
resource body and infill the step out drilling.

San Miguel – Pushing the Limits of the Resource
San Miguel has become a cornerstone resource for the Cusi Project, boasting Indicated resources of
1.3 million tonnes at 258 g/t AgEq and Inferred resources of 2.03 million tonnes at 249 g/t AgEq. The
2026 surface drilling campaign will look beyond the current resource boundaries, aggressively testing
both the lateral and vertical extents of the deposit. This aims to unlock significant upside, as historical
drilling on the western edges failed to properly intersect the vein due to being drilled at too steep of a dip
or without sufficient step-backs.

Promontorio Underground – Connecting Step outs
With dewatering completed and rehabilitation efforts now well underway, Silverco is initiating targeted
underground drilling at Promontorio. This campaign primarily focuses on validating and increasing the
definition of initial mining areas to effectively derisk upcoming restart activities.
Initial mining is envisioned to begin on the Promontorio East veins, which boast exceptional undiluted
high-grade material with Measured and Indicated grades of 295 g/t AgEq and Inferred grades of 301 g/t
AgEq. Current drilling is specifically aimed at optimizing mine planning and targeting near-term resource
expansion that can be integrated into the short-term mine plan to reduce initial development
requirements.
