Silver Storm Mining has received approvals from the Mexican authorities to construct 62 drill pads and 27 access roads at its wholly owned La Parrilla Silver Mine Complex in Durango State.
The federal agency Secretaria de Medio Ambiente y Recursos Naturales (SEMARNAT) issued the permits, which are valid for four years.

The new permits allow Silver Storm to proceed with surface drilling across 24 sites at the La Ilusion-Argenis target, and 32 sites at the 14 Marcos and Rosarios-C340 West Extension sites.
These developments form part of an initial exploration plan for the C340 and 14 Marcos targets.
At the C340 area, Silver Storm’s objectives include upgrading inferred resources from the previous Rosarios mine to the indicated classification and expanding resource potential by targeting areas to the west of known mineralisation.
The company’s plan covers around 3,600m of surface drilling in this location.
Additional work also includes testing zones of higher-grade mineralisation at the upper levels of the C193 zone.
Exploration at the 14 Marcos target will involve approximately 3,000m of drilling to a depth of 300m.
Historical artisanal mining at this site extended to approximately 100m deep, and the company aims to examine the projected continuation of the mined vein, located to the south of existing developments at the Rosarios mine.
Silver Storm Mining president and CEO Greg McKenzie said: “Securing the permits to conduct surface drilling is an important milestone for our 2026 exploration programme at La Parrilla.
“With multiple promising surface exploration targets on the La Parrilla land package, we are excited about the potential to grow the resource footprint on the property.”
In addition to the exploration permits, SEMARNAT has authorised the continued operation of La Parrilla’s tailings storage facility for an additional ten years.
The previous environmental operating licence was due to expire in the third quarter of 2026.
Last month, the company announced the mobilisation of contractors for underground development at its fully owned past producing La Parrilla Silver Mine Complex.
