Summary:Silver Storm secures full official drill permits for its La Parrilla silver mine in Durango, clearing the path for a 6,000m underground drilling program to expand silver mineral resources....
Silver Storm Mining (TSX.V: SVRS) has officially secured all required local, environmental and mining permits to launch its large-scale underground drill campaign at the wholly-owned La Parrilla silver mine in Durango, Mexico. After multi-month regulatory review with Mexican state mining authorities, the full set of drill permits removes the biggest operational barrier to executing the planned 6,000m La Parrilla mine drilling program, targeting high-grade silver-lead-zinc vein systems across Quebradillas, San Marcos and Rosarios mine zones. Located within Mexico’s prolific Silver Belt, La Parrilla previously produced 34.3M silver-equivalent ounces between 2005–2019; the permitted drilling aims to expand indicated mineral resources and accelerate the mine’s full operational restart roadmap amid sustained tight global silver supply for electronics and renewable energy.
Project & Permit Approval Overview
La Parrilla spans 38,128 hectares via 40 contiguous mining concessions, equipped with an idle 2,000 tpd processing plant and five underground mine portals, positioned 76km southeast of Durango city with full highway and power infrastructure access. Before receiving formal drill permits, Silver Storm submitted comprehensive environmental impact assessments, community consultation records and underground safety engineering documents to Mexico’s Secretaría de Economía and local municipal regulators.

The secured permits authorize continuous underground drill mobilization, underground core sample storage, temporary drill waste stockpiles and full geochemical sampling operations within existing underground workings, eliminating restrictions that previously delayed rig deployment. All compliance clauses cover water management, waste rock handling and local indigenous community environmental monitoring requirements mandated by Durango mining regulations.
Geological Value of Permitted Drilling Targets
The La Parrilla mine drilling campaign focuses on structurally controlled mesothermal silver vein systems formed along Eocene intrusive contact zones, a deposit model responsible for most high-grade silver assets across central Mexico’s Silver Belt.
Quebradillas Zone (3,500m): Prior drill intercepts hit intervals of 473 g/t AgEq over 3.6m in the San Nicolas sub-zone; drilling will extend strike and depth of C460/C550 sulphide replacement bodies.
Rosarios Zone (1,500m): 1.75km-long mineralised fault vein with thickness up to 14m, with untested western extensions below historic stoping levels.
San Marcos Zone (1,000m): Shallow breccia-hosted silver mineralisation ready for resource upgrade from inferred to indicated category.
Diamond core drilling will capture intact vein samples to map grade continuity, vein thickness and pathfinder element distribution, delivering critical geological data to expand the project’s existing mineral resource inventory.
Strategic Significance of Secured Drill Permits
Obtaining full permits for La Parrilla mine drilling marks a critical de-risking milestone for Silver Storm’s restart strategy. Without regulatory clearance, underground drill rig mobilization and resource expansion work could not proceed, delaying the timeline to restart the 2,000 tpd mill.
From a market perspective, validated permit approval signals to investors the project’s operational readiness at a time silver prices remain supported by industrial demand from solar panels, EV wiring and electronic soldering. The expanded resource base unlocked by drilling will also strengthen offtake negotiation leverage with global precious metal smelters in North America.
Operationally, the 12-month valid permit window provides flexible scheduling for drill crews, allowing phased mobilization without rushed timelines and reducing third-party contractor downtime costs.

Silver Storm’s successful acquisition of complete drill permits clears all regulatory hurdles to launch the landmark 6,000m La Parrilla mine drilling program. This critical regulatory milestone unlocks systematic underground exploration across three high-potential silver mine zones, designed to expand mineral resources and advance the restart of one of Mexico’s most prolific historic silver producers. As drill rigs mobilize and core assay data rolls out through late 2026, the market will closely track resource growth results that will define La Parrilla’s long-term production capacity amid robust global industrial silver demand.
